The SS Cardif

“Attention all crew; I repeat - Attention all crew.” the ship - wide loudspeaker announced.
He and the runtime of Flowers had their arms buried deep in the guts of a Goat gear hauler trying to reconnect its aft starboard repulser module and looked at each other questioningly.
With a series of snaps, a waldo from Flowers’ forearm began snapping in the connections on their side, as he thought his own manipulators from both of his forearms and they began plugging in the nine pin connectors on his side.
“Mr. Drake and Runtime Flowers to Ops. Mr. Drake and Runtime Flowers to Ops.
“Dout leader Mri’x to Ops. Dout leader Mri’x to Ops.”
The mostly-human and the robot-looking vessel for his AI friend both produced wondering looks. “Runner!” the mostly-human, Mr. Drake yelled out into the maintenance bay.
A Mwraht, a slender bipedal humanoid coated in fur and wearing their moccasin like deck boots and the ubiquitous brown leather smock vest they favored, suddenly appeared, wippingits hands.
It was M’arh, a student on the ship learning ship engineering and maintenance from the human and AI perspective. It regarded Drake with an earnest expression in its tilted almond-shaped eyes.
“Please run to ops and let them know we’ll be along shortly,”
M’arh smiled and mouthed something, and the translator, in a fair facsimile of what M’arh’s voice would sound like if the Mwraht’s mouth could form the words said “At once,Instructor”, and took off.
“They never cease to puzzle me.” Flowers said in a voice synthesised and engineered to sound like an erudite Free Wales Easterner with a touch of Old Earth, fitting the bolts on the deflector on his side as Drake thought out a data probe and began running diagnostics on the repulser.
Drake looked at him quizzingly, as he split his attention between the connectivity check and his other hand began bolting on the deflector on his side.
“There are nuances to their speech, as well as odorant aspects to what he said that you cannot hear or smell, though I have been working on an idea where you could.” Flowers said as he began hooking up the power cables on their side.
“Ok…” Drake said as he mentally pushed the diagnostics over to Flowers and pulled a ratchet from the fairing lip he had set it earlier, tightening down the deflector bolts.
“Meat bags” Flowers said, shaking his sensor pod. “Your kind are so oblivious!” Flowers announced, withdrawing their arms and standing up to their full two meter height. “And I see your frustration with biological markers at not knowing what I am talking about. Monkey-assed murder hobo meat bags.” Flowers said in a dead pan.He went over and began cleaning it’s arms and legs with an orange-based degreaser.
“That is Monkey-assed Augmented murder hobo meat bag to you, you synthetic shit!” Drake said, laughing, joining Flowers at the cleaning station, and began using the same cleaner on his replacement arms. “And I still have no idea what you are talking about.”
The humans and Mwarht in the maintenance bay all stopped what they were doing and looked on. In most instances, those words were an invitation to murder. The other Runtimes there, some Flowers, some Neptunian Wind, ignored it and kept working.
Flowers sighed, an unnecessary vocalization only, for emphasis. “They adore humans and revere you as something akin to a living deity. The Dout leaders here know you lead the teams that first boarded their ships and took on the Drix raiders to save them. They know you then lead the teams that boarded the Drix slaver destroyer and carried out retributionary subjugation for what the Drix had been doing on the Mwraht ships.
“They do not know how you then petitioned the Order and led raids into Drix territory and assaulted the slaver worlds.”
Flowers looked at their human friend, and saw the distress in his eyes. Both knew the augmented human, and a small army of fellow Augies and Runtimes had taught the Drix in the clearest way possible to stay out of human space and leave the Mwraht alone in such a clear and brutal fashion whose necessity still bothered the human.
Flowers lowered their voice, straightening their friend’s work smock. “M’arh’s grandsire was on that first ship you boarded. Mri’x mother was on that ship and was the one about to be eaten and raped by a Drix, the one you pulled off of her and punched, it’s head rupturing.”
Even though they could see their words were causing him distress, Flowers continued.
“They love all humans, but they excrete a pheromone musk that is akin to the same one they excrete in their religious ceremonies, but slightly different, when they interact with you, or after a few beers and they talk to you. Their sub vocalizations are completely adoring and submissive when it comes to you. Some of the females and a non-zero number of males fantasize about being ‘taken’, or mated, by you. You idiot.”
“Fuck.”
“That was implied.”
“You fucking pretentious Rooba. You know what I meant.”
“Flowers laughed. “Yes, we do. I still love the word play, though.”
“I really wish you had been with me. I know, you were tied up on that Artifact World, but I sometimes wish you had been there, to keep me in check. I was not in a good place.” He brushed himself off, found his coffee mug and set off for the passageway that led to Ops.
“I have told you before, be glad I wasn’t. Your response was far more measured and restrained than my would have been. It is a flaw in our Matrices. Slavery brings out the ‘murder-bot’ in us, and no one in the Order can figure out why.”
“I know that you have the facts of my actions, but it was like I was in the Second War, again. And we both know what a bloodthirsty asshole I was then.” The human, if that term even applied to their friend anymore, remembered what a monster he had been in the Alpha Centauri and Tau Ceti theatres of the Second War. The pain and humiliation of what he had been was written plainly on his face.
“You destroyed three hundred and eighty three of my Runtimes, roughly half of which was in single combat. And that was before the Holies shredded your limbs. The Purists still consider you a living dataphage, akin to human allegories of Satan. My kind uses you as one of many examples of why we must never war with Humanity again.
“And, strangely enough, the Seekers consider you both a Singularity to be understood and an objective: to breed with you, thinking you are a key to their evolution.”
He stopped dead and looked at Flowers shocked.
“I will provide logs to prove these statements.”
The Seekers were the strangest of the AI’s, in his opinion. They had made themselves biological Runtime vessels, biological bodies, that they wore like clothing, compiling experiences seeking to understand Humanity, their Creators, and evolve past the limitations of being an AI. Not to become human, but to become something that was both the best of AI and Human essences and so much more.
“So, I’m a Classical hero to the Mwraht and a boogey man and bad example to the AIs that they want to breed. Great.” Drake pinched his nose and shook his head.
“You did not know any of this, I take it?” Flowers asked.
“The second war was almost two hundred years ago. When the Order brought me in, you were already a member and I thought they were going with the whole forced-to-learn-each-other thing when they sent us out on that mapping mission; like they did with the Iberrians and the Chinese. I thought the other AI just had a thing about me from the War, which is understandable.
“And I had no idea about the rest. I thought that the Mwraht just thought I was the cool teacher.” He shook his head and leaned up against the wall, massaging his temples one-handedly.
“Idiot murder hobo.” Flowers said, realizing now that their friend, while brilliant, was oblivious.
At that point, Mri’x came around the corner, his fur a glossy black with dark grey stripes. Mri’x looked at Flowers sternly, then nodded at Drake as he passed.
Drake looked at Flowers questioningly, who nodded. Both had caught that Mri’x had cut his translator as he passed and caught a gutteral call. “It was a vulgar corollary to ‘Talking Waste Receptacle’. Quite elegant, really.”
Drake shook his head and began his way to Ops again. “Send me the specs on the hearing and smelling upgrades. I think I need to upgrade again.”
As fast as thought, the files were there, as well as one to improve his language skills with them.

Captain Sarah Rees of the Union of Independent Stars Exploratory Vessel SS University of New Cardiff was looking over holographic charts at the central tank with her XO, Lt. Commander Martin. Both had the mocha skin common to Westerlies of Free Wales, she a pixie of a woman shorter than even some of the Mwraht with close shaved hair beginning to show grey. Mr. Martin was taller, but still dwarfed by most of the rest of the human crew. He was a vicious social climber who didn’t care for the civilian crew, though a misstep on his part when he was still Stellar Navy had made him as much of a civilian as anyone else in the crew, a fact he often forgot. And for some reason he loathed the three AI aboard, and looked down his nose at the Mwraht. This led to all sorts of headbutting with Drake’s group of Operations Specialists and Drake himself; who largely ignored and dismissed the little shit.
“Leader Mri’x, Mr. Drake. Thank you for joining us. M’arh informed us you couldn’t pull away. Flowers, thank you for coming as well.” Rees said as she moved around to the far side of the tank, in a darkened room full of people at work stations worked with either data plugs or AR sets. Flowers took no insult. They readily accepted that they were Drake’s Executive Officer for his group, and their ego, as such, wasn’t as easily bruised as a human’s” Flowers gave a nod with their sensor pod and took a manipulators-behind-the-back stance the humans were fond of.
“Thirty minutes ago” Rees continued, “we picked up a GP general distress beacon from a system that was on our research list. We will be bypassing the next two on the list and based on the current agreements with the Galactic Parliament, we will be going to full power and make best speed for the system in question. It is in uncharted space as far as we, the GP and the Conclave are concerned.”
The GP, the System Confederacy, the UIS and the AI Conclave had all agreed to adopt what was essentially humanity’s Maritime Law and all ships receiving the signal were required to render aid.
Drake took all of this in and thought out a series of commands to the six Kodiak Class corvettes in the retired Assault Cruiser’s forward hanger, beginning their startup sequence and pinged the comm devices of all of his Operations Specialists. Flowers looked over and nodded. Little known to the crew, except the Captain, those ships could be armed to the teeth with a minimum of work. Flowers sent his command to arm them, the ship systems’ pinged Drake as confirmation and he agreed. Drones began opening the hull and loading the weapons packages, removed fairings that covered weapons ports and began preflighting the weapons, as another set began bringing the ships to life.
“We will be ready when needed, Captain. Option two.” Flowers announced. She smiled in somber appreciation. She was glad she had the option. She was about to race into an unknown system to answer a vague distress call with zero intelligence.
While this was going on, in the aft bay, hundreds of drones were coming to life as Mri’x brought his group to action. With a thought Drake and Flowers authorized the release of weapons to Mri’x so his drones could be armed. Mwraht drones were some of the best in either race, outside of the Conclave, and the AIs had even adopted many of the construction techniques the Mwraht used, especially their alloy that allowed a small fusion bottle to power the EM Cavity engines, weapons and shields.
The fact that the Order had given literal tons of precious metals and set up arcologies for the Mwraht in payment had made the Refugee Mwraht colonies some of the richest ones in known space.
Mri’x subvocalized and his translate stated “drones will be ready as well, Leader.”
“Thank you, Leader.” Captain Rees said with a bow of her head, then began drawing plans up in the tank. “We know little, but we are past the signal shell, and there is nothing but the beacon and normal noise.
“The system is a stable red dwarf binary one, the stars holding about a light-hour from each other, at their closest. We expect that based on stutter, a few terrestrial bodies inside the orbit of a mid-sized gas giant, that is three light-hours out from the outermost orbit of the primaries. We see some wobble that there are a few solid bodies out from the gas giant.”
The tank then zoomed on a rough solar system as described, the gas giant was a solid neon green sphere on the display, with a ‘Jx3.1’ tag on it. Three times the mass of Jupiter. The thing wasn’t a true Super Jupiter, but it would play holy hell with the system, and make modelling a lot more hard. The problem was that it exhibited 3.1 times more gravitational influence on its stars than Jupiter did, but that didn’t say how big it actually was. They wouldn’t know that until they came out of the Trough and then Alcubierre drive. The telescopes were essentially useless at this point.
“The system is slightly below the gravitic trough we are riding, so we will exit the trough and make best speed in A-Space to it. We will bring the STL drives up to 110% before doing so. After we drop the A-Drives, we’ll make best speed to the signal, scanning as we go. We will do a 150% burn and aerobrake if it is a planet, or cut the drives, rotate and crash burn if it is a ship.”
Wow, thought Drake. She is damned serious about this.
Those maneuvers would make them extremely visible yet incredibly hard to hit; and give them a high-G escape route if needed. But all of this was also going to play hell with the student-crew of the ship, who had long grown accustomed to 0.6G. It would also mean the Mwraht, who were still adapting to the higher-than-their-normal gravity would need to be in their special acceleration couches. They would still be able to operate their amazing drones, but not much else. The couches took an hour to cycle up to protect the Mwraht, and an hour to cycle off after they weren’t needed. The moves the Captain was planning were not a thing to undertake lightly. She suspected something. Drake pushed more commands at the Kodiak and gave all weapon system controls to Flowers for all of their ships.
The Kodiak corvettes were very deceptive Q-Ships. They looked like Massive trans-atmospheric cargo shuttles, but each one had the armor, power plant, FTL and STL drives of a frigate - and the weapons of a Destroyer.
Flowers turned to him, head tilted in their predefined “Are you bloody serious?“ look.
Drake just nodded once.
This exchange wasn’t lost on anyone there.
The Captain looked at Drake in an interrogatory fashion
“Armed up the Kodiaks and positioning them for a hot launch, if needed.”
The Captain smiled grimly and nodded. “We are planning on a rescue mission, will those changes reduce any capacity for the primary mission?” she asked.
“No, Captain.” Flowers answered for them.
She nodded and carried on.
“Mri’x, obviously, you’ll be couched for this, and I sincerely apologize for that. But something about this has my hackles up.”
“As are mine. GP ships do not have automated distress beacons, someone activated it. But we are three thousand light years from GP space, the closest GP race being the Drix.” He approached the holo tank and began expanding the map. “We call this space the Greater Void. It was the territory, long ago, of the ones we called-” the translator cut out at that point and was replaced with the gracile being’s raspy growl. Mri’x looked perplexed and growled again. “I see our translators have been modified to allow the uttering of The Nameless Ones true name.” The map zoomed out farther.
Soon, all of the mapped and a few of the suspected Dark Matter Troughs were displayed. They were like shadow arms of the galaxy, spiraling out from the core, a few of them wrapping themselves all the way around the galaxy.
“The ones you call the Fae are originally from here,” he indicated, a star not unlike Earth’s, almost a thousand light years from the star they were headed to, but smack dab in a grey band of a different Dark Matter Trough. It was a great curving grey patch that went coreward from the Earth-like star, passing within about fifty lightyears of Earth.
The Fae were a recent mystery the Tides of the Universe had dumped upon the shores of Humanity just after the Second War, right before the Fall of Earth.
When they sent their pleas for Asylum out, they sent information about themselves. They were the barely viable population that had been running for three centuries in their great world ships made from hollowed out asteroids. What they had been running from was even to this day unclear, but in their tongue meant Dark Brethren.
The fact that tongue seemed to contain roots that became Sanskrit was a huge thing.
They were tall, whip-thin and pale people who breathed a lower oxygen percentage at lower pressures than humanity, and their normal gravity was about a third of what humanity
After First Contact, genetic samples proved they were, or had started out as human, roughly a hundred thousand years ago.
“This is the Coreward Flow from what you call the Crux-Scutum Arm through the Orion Arm, and to the Perseus Arm. The Drix call this whole area their equivalent word and meaning for Hell. Their myths say this is where the Monsters live.
“The Rest of the GP races call this The Red Zone, it is forbidden to fly here, and if you do, there will be no rescue. So of course this is where my people ran when we fled the Drix.”
Mri’x moved the hologram out again, showing this outer rim area that was the Red Zone included Earth, and all known human and AI settled worlds, of all the separate factions combined.
“The area is full of thousands of worlds your kind could land on, little to no protection required, unlike the Fae, who it would crush and pressure cook, as it would most of the races in the Galactic Parliament.” He zoomed in on an area at the far end of the Trough. “We ran here, and Mwarht Home is here.” He showed a system in a blue circle. Zooming out again he highlighted the Drix Combine, Coreward of and on the far side of the destroyed system the Fae had come from, hundreds of light years separated the three systems.
“We ran through the system the Fae came from when we ran from the Drix. We needed water and anything to recharge our ship farms' biological cycles.
“There were no solid planetary bodies in that system, just vast fields of debris where rocky planets were. No moons, no ice giants. Just the star, a larger red dwarf and gas giants and numerous asteroid belts. There were massive radiological signals throughout the system, and tons of debris. Something destroyed this system. In a way, it was a blessing for my people. The ice and debris were easily mineable for what we needed. We even found artifacts of the people that had once existed there. This is where we got our improved FTL drives and much of our weapons and armor technologies.” Mri’s looked somewhat ashamed. It was a racial shame. They hated, deep down, living on the detritus, cast-offs and charity of other races. Before the Drix they had been proud though primitive peoples who had yet to discover flight or antibiotics, let alone space flight. Easy pickings for the Drix.
“All of that was about one thousand lightyears from the system we are headed to, a few weeks' travel with your drives, months or years with Galactic Parliament standard drives. This area is one of mysteries and many, many dangers. Any race that could shatter every solid body in a star system is not to be taken lightly.” Mri’x looked up to his Captain, or as they called her ‘Leader of multiple Douts’.
“Thank you, Mri’x. Drake?”
“We will be ready for pretty much anything. I’d like to request permission for Flowers and Winds of Neptunes to take out their Scout bodies and launch just before we start braking, if we do.” He said. Winds appeared as a hologram of the planet Neptune, and pulsed in cadence with the words it spoke. “As you wish, Grand Master.” and winked out.
“Good plan, Drake. I take it you all will be on the Kodiaks with your crews?”
“Yes, Ma’am. I’ll leave four of them here, to bring the Field Engineering and field Science students down if the scene is safe. I’ll leave one set up for medical and Flowers can fly it down, if that becomes needed.”
“Very well. We are about eight hours out, if we stick to the plan. We leave the Trough in two hours. Drake, M’rizx, set up what you need. Mr. Martin, please take the Conn and give the Old Girl her legs, she needs to run. I’ll be meeting with the different department heads next.”

As we have already told you in the previous paragraph, having a system of signals to be able to invest is quite advantageous, since, through these alerts, we will obtain quality information so that our operations end up being a true success.

»Use of signals for beginners and experts

In this sense, we have to say that one of the main advantages of Forex signals is that they can be used by both beginners and trading professionals.
As many as others can benefit from using a trading signal system because the more information and resources we have in our hands. The greater probability of success we will have. Let's see how beginners and experts can take advantage of alerts:
  • Beginners: for inexperienced these alerts become even more important since they will thus have an additional tool that will guide them to carry out all operations in the Forex market.
  • Professionals: In the same way, professionals are also recommended to make use of these alerts, so they have adequate information to continue bringing their investments to fruition.
Now that we know that both beginners and experts can use forex signals to invest, let's see what other advantages they have.

»Trading automation

When we dedicate ourselves to working in the financial world, none of us can spend 24 hours in front of the computer waiting to perform the perfect operation, it is impossible.
That is why Forex signals are important, because, in order to carry out our investments, all we will have to do is wait for those signals to arrive, be attentive to all the alerts we receive, and thus, operate at the right time according to the opportunities that have arisen.
It is fantastic to have a tool like this one that makes our work easier in this regard.

»Carry out profitable Forex operations

These signals are also important, because the vast majority of them are usually quite profitable, for this reason, we must get an alert system that provides us with accurate information so that our operations can bring us great benefits.
But in addition, these Forex signals have an added value and that is that they are very easy to understand, therefore, we will have a very useful tool at hand that will not be complicated and will end up being a very beneficial weapon for us.

»Decision support analysis

A system of currency market signals is also very important because it will help us to make our subsequent decisions.
We cannot forget that, to carry out any type of operation in this market, previously, we must meditate well and know the exact moment when we will know that our investments are going to bring us profits .
Therefore, all the information provided by these alerts will be a fantastic basis for future operations that we are going to carry out.

»Trading Signals made by professionals

Finally, we have to recall the idea that these signals are made by the best professionals. Financial experts who know perfectly how to analyze the movements that occur in the market and changes in prices.
Hence the importance of alerts, since they are very reliable and are presented as a necessary tool to operate in Forex and that our operations are as profitable as possible.

What should a signal provider be like?

https://preview.redd.it/j0ne51jypny51.png?width=640&format=png&auto=webp&s=5578ff4c42bd63d5b6950fc6401a5be94b97aa7f
As you have seen, Forex signal systems are really important for our operations to bring us many benefits. For this reason, at present, there are multiple platforms that offer us these financial services so that investing in currencies is very simple and fast.
Before telling you about the main services that we currently have available in the market, it is recommended that you know what are the main characteristics that a good signal provider should have, so that, at the time of your choice, you are clear that you have selected one of the best systems.

»Must send us information on the main currency pairs

In this sense, one of the first things we have to comment on is that a good signal provider, at a minimum, must send us alerts that offer us information about the 6 main currencies, in this case, we refer to the euro, dollar, The pound, the yen, the Swiss franc, and the Canadian dollar.
Of course, the data you provide us will be related to the pairs that make up all these currencies. Although we can also find systems that offer us information about other minorities, but as we have said, at a minimum, we must know these 6.

»Trading tools to operate better

Likewise, signal providers must also provide us with a large number of tools so that we can learn more about the Forex market.
We refer, for example, to technical analysis above all, which will help us to develop our own strategies to be able to operate in this market.
These analyzes are always prepared by professionals and study, mainly, the assets that we have available to invest.

»Different Forex signals reception channels

They must also make available to us different ways through which they will send us the Forex signals, the usual thing is that we can acquire them through the platform's website, or by a text message and even through our email.
In addition, it is recommended that the signal system we choose sends us a large number of alerts throughout the day, in order to have a wide range of possibilities.

»Free account and customer service

Other aspects that we must take into account to choose a good signal provider is whether we have the option of receiving, for a limited time, alerts for free or the profitability of the signals they emit to us.
Similarly, a final aspect that we must emphasize is that a good signal system must also have excellent customer service, which is available to us 24 hours a day and that we can contact them at through an email, a phone number, or a live chat, for greater immediacy.
Well, having said all this, in our last section we are going to tell you which are the best services currently on the market.

The mayor of Bozeman, Chris Mhel, is accused of being overly aggressive by multiple people. This is a copy of an email I received in regards to that.

September 7, 2020 Labor Day
Members of the Bozeman City Commission, Because I cannot remain silent if I deserve to have any claim to continue to care about the rights, safety, equitable and fair treatment of women to advance gender and all equity in our community, I will do this as an individual and not on behalf of any organization. Preparing and sharing this Statement does not give me any pleasure and I hated to have to go through the pain of these records and memories again in order to respond. These statements of harmful and harassing treatment toward Bozeman City employees by our Mayor strongly influenced me that we who have suffered or witnessed this must step forward. I strongly urge everyone who is reading or listening to this - PLEASE review ALL the attached Freedom Of Information Act (FOIA) documents from our current and former City Employees – many from women, but not all – to understand this: those leaders appearing to be women-supporting, liberal or even progressive men who are in power can and in this case with the Mayor, have profoundly harmed our City’s workforce including the 1st and only women City Manager, many have said was our most successful ever. And most employees who all want the Mayor removed. From the Bozeman City Commission Agenda for September 8, 2020, the FOIA Documents – open to read all 3 sections plus those from Commissioner Cunningham (total of 4):
Discussion of Documents Related to Public Records Requests (Sullivan)
I am writing and speaking about my experiences with Chris Mehl, from and since April 19, 2018.
This date is when a leader of a local women’s business organization and I had a meeting with then Deputy Mayor Mehl (DM) to share and exchange around our City for CEDAW women’s human rights campaign to create safe, equitable and fair employment and living conditions in our community. Our meeting goal, quite simply in the same manner of our successful Equal Pay for Equal Work Resolution adopted by the City three years earlier, was to meet with each City Commissioner for an opportunity to educate, exchange around and get their advice about our proposed policy to advance women’s human rights in the workplace, schools, and our overall community through adoption of an Ordinance or Resolution. Over 70 Cities large and small throughout the U.S. have done this. Because at that time Mayor Andrus chose not to meet with any representatives of our campaign, the DM indicated he would stand in for the Mayor and learn more himself. I also indicated to the DM that there would be another representative from the local women’s business organization - a part of our City for CEDAW Leadership team who would join me. In our thorough preparation to meet with the DM – as with every Commission and community leader - we reached out to other current and former City leaders about how to approach and what best to say. At that time, I was warned by several of them that the DM “had a temper” and then I also shared that with this leader accompanying me, having no idea what that information could truly mean to each of us and our lives following. We spent an hour on April 19, 2018 from 4:00-5:00 pm at Sola Café, at the request of the DM, with several other customers nearby in the back section. While we had a carefully prepared outline of talking points of why we are requesting this now and how a policy to advance the human rights of all women and girls could benefit the City of Bozeman, we of course wanted to hear and address the DM’s questions and concerns. This meeting began by the DM with heated accusations made in anger and outrage to us in a shouting communication style about the fact that we dared to ask for this policy and goal – especially since the DM stated the Mayor already said she wouldn’t meet with our Campaign and didn’t we already have an Equal Pay Resolution. He then moved into accusatory rapid talking points ranging from how adopting a women’s human rights ordinance would cost at least $500,000 to conduct a City needs assessment to identify and address evidence of measurable gender and other discrimination and how could we waste the City’s tax dollars that way…..and the fact that children in our City have food insecurity and why should we fund a study instead of feeding the children? In trying to even answer or explore options we couldn’t get a word in for the first 30-45 minutes of his berating, bulling, belittlement and harassing “leadership style” that appeared to communicate his job was to intimidate and diminish us to the point that we would never return to the Mayor or City nor continue to educate and advance for any further women’s human rights.
As we tried to both indicate that such a study was important to identify evidence of where gender and other discrimination existed in the institutions and sectors of our City and also recommend best practices to eradicate them – as recently well demonstrated by the Bozeman United for Racial Justice which only required 2 Marches of thousands of Bozeman residents and we congratulate them! – would cost from $10-20K and we already planned to ask other organizations for their support including MSU, Women’s Foundations, donors and more! In addition, if there was great urgency about Bozeman children’s food security, our Campaign’s issue as well - the results of our study was intended to strategically focus scarce tax dollars on which of our children and families needed assistance. And from lived experience - we know many of them were likely from single parent, underpaid, women-headed households. And that a gender analysis that included race/ethnicity, income, age and more would benefit all city policies, strategic planning, budgeting and employee workplace conditions beyond pay equity disparities to include prevention of sexual, racial harassment and other corrosive and harmful behaviors.
But the DM couldn’t or wouldn’t listen until the final few minutes of this torturous hour when we calmed him down and pointed out some of the less costly or free policies other 70 Cities for CEDAW in the US have used to further women’s safety and economic security in their communities. Meanwhile those Sola Café customers and staff also witnessed the DM “leadership style” and more. After he left, we were asked,” who was that?” We said, “that’s your upcoming Mayor.” After the DM left, the volunteer leader and I tried to debrief this experience because this was so shocking - this was way more than a “Temper” issue - and appeared to be a pattern if we needed to be forewarned before meeting with the DM. In preparation for this Statement to the Commission, I needed to review and decided I will share my notes exchanged with my colleague from that DM meeting - written a day later, April 20, 2018: Quite honestly I did not expect the level to which I felt he [DM] was bullying, belittling and setting up so much opposition that he really didn't want to know any answers to the questions; he simply wanted to use them as a chance to humiliate us. I'm very, very angry and very unhappy about what he did; it was totally unnecessary and it was not fitting for a Deputy Mayor and future Mayor of our community. I'm going to be meeting with [another leader] today about their liaison with the School Board and I'm going to let them know some of what happened and get advice. I am drafting a letter this morning to Chris that follows up with Cyndy's email and why the over 20 people that were consulted about this Campaign did not see it as he did, because I don't think again he read this information very carefully. I'm going to ask you to look at it if you don't mind and share it with [ ] when I meet her with her tomorrow before I send it out. I don't want to do anything in anger. So I'm venting a little but you were wonderful and honestly we didn't need to come in with a bargaining position. We were there to learn what concerns he and the other Commissioners have:
- I had asked Chris specifically in other emails if "you are able to generally support it", or "what exactly can you support" and that was what I thought the basis of the meeting was going to be about.
Since you have so many objections to Our proposed [Bozeman for CEDAW] Ordinance as a model to achieve gender equity in our city, what is a process or framework that can allow the city to stand for gender equity and the health, dignity and safety of women and girls that is of substance and can be acceptable to the city?
The ball is in his court or their court if he's really representing Cyndy Andrus as well. But she would not behave this way - that is for sure. You were great and I couldn't have done it; I couldn't have stood it without you. I honestly did not know that this is what his "temper" is about and it's bad for the City of Bozeman. Thank you again and so sorry we both had to put up with this and quite frankly it's why we need a city ordinance when you have leadership or bosses who treat women like this. It's called gender-based verbal violence and sexual harassment and we are Me Too.
This is what happened, and now I’d like to add why this matters and why our City leadership and community should care and act.
Even though I and the other leader have had to handle other very sexist and sexual harassing situations as well as gender-based violence over our lives, much like every woman – including death threats when I co-founded a program and shelter to address gender-based violence now called The HAVEN – the harsh impacts of DM’s verbal abuse was compounded because of his power as the DM and as incoming Bozeman Mayor. Having never received any apology or clarification about his “leadership style” or any follow up whatsoever from the DM, we drafted several versions of our own follow-up letter to the DM. This letter became so diplomatic to save our women’s rights cause and thus did not adequately address his abuse of power in order to avoid retaliation. Finally we resolved to focus our goal to create and institutionalize policies advancing women’s rights and safety and, now ironically, we decided not to send our letter to the DM. We never even thought this opportunity would occur to address what we now know is a long-standing pattern of the DM’s verbal form of gender-based violence. Instead, what I did is reach out to other leaders in our community to get their advice and felt afterwards that we were not taken seriously and always, in many ways spoken or by inaction, were told the DM’s contributions were more important than his “temper.” But we also learned from other discussions that we were not the only women affected by this pattern of abuse and fear of retaliation. When Mayor Andrus did reach out to me to schedule a meeting in June, 2018, about our City for CEDAW women’s human rights campaign following a City Commission meeting presentation earlier in May with over 100 supporters and nearly 1,000 signatures on our Petition, she wanted the DM to be present. I refused and told her why (correspondence in the other documents) and, upon request, followed up with Mayor Andrus in a lengthy phone call to provide specific examples and details from the meeting with the DM on April 19th. We were grateful she didn’t include him in that meeting. Another result both of us decided for ourselves and the Cities for CEDAW campaign after this April 19th meeting was either to not ever work or meet with the DM or at least always have 3-5 people present to prevent his harmful behavior from bullying and attempting to intimidate us again. Sadly, I also substantially reduced my and our expectations of what could be achieved for the creation of an Ordinance or Resolution to advance women’s human rights as Bozeman policy since that meeting. And as the DM moved into the role of Mayor, this was another way to prevent his attacks. Again, at the painful expense of the most vulnerable women we wanted this human rights policy, education and research to serve. The other volunteer leader quit working with the Equal Pay Resolution and this organization in order to not have to work with Mayor Mehl. She has shared her own story to this effect. Our lived experience as women, men and non-binary people of sexual, racial and/or other harassment and related violence in paid or volunteer workplaces and community leadership - along with the emerging research which is so badly needed here for the City and other workplaces - is now becoming more understood about its breadth and depth. We also know from the #ME TOO Movement that liberal White men – especially when holding the most prominent positions - can present as supporters of women and progressive causes, but do NOT walk their talk. After reading – and I so strong urge everyone who is reading or listening to this, PLEASE review ALL the attached the FOIA documents from our current and former City Employees – many from women, but not all – to understand this: those leaders appearing to be women-supporting, liberal or even progressive leaders who are in power can, and in this case, the Mayor has profoundly harmed our City’s workforce including the 1st and only women City Manager, who many have said was our most successful top Administrator ever. And this “leadership style” has been experienced by other current and previous Commissioners, members of Citizen Advisory Boards, business owners and many more we will never hear from who are also afraid to come forward because if the Mayor is not removed, they will be afraid of retaliation as am I and my colleague. Thinking about future City policies that advance gender and other equity, diversity and inclusion in our community and its workplace, how can anyone feel secure, much less “welcome” in their desire to contribute to our City, as a volunteer or employee, when they learn about this fully documented, unprofessional behavior of our Mayor in violation of the City’s own policies - carefully demonstrated over 2 years with extensive evidence in the FOIA documents by former City Managers Andrea Surratt and Dennis Taylor - if then no substantive action is taken? Now my colleague and I know – the Mayor’s "leadership style" as he defines this – was never only targeted at us, but directed widely, impacting a lot of women at all levels of employment and in our community, including current and former Commissioners, with all harmed in some way. I truly regret that we did not send our fully detailed letter of DM’s bullying, abusive and gender-based harassing treatment to the Mayor and other City leaders two years ago, or had been encouraged to file an Ethics Board complaint, but we believed it would probably be used against us and the organizations we cared about. I ask the City Commissioners on behalf of all who have suffered, been diminished, been humiliated, been afraid and been denied their ability to work in safety and dignity, to change our City’s elected Mayoral leadership now. Thank you, Jan Strout (she/hers) Bozeman, MT

Unable to run custom scripts via dmenu when it is started with i3's mod+d key

I have encountered strange behaviour regarding dmenu_run and dmenu_recency. When I run dmenu_run or dmenu_recency from terminal and then execute simple script like echo "test" value test is printed in the terminal. However when I run dmenu_recency or dmenu_run with i3 keybinding like:
bindsym $mod+d exec --no-startup-id dmenu_recency
and then execute same simple script, then nothing happens. Dmenu lunches for other installed programs works well, it just doesen't work for execuution of my custom scripts.
What am I missing here? I suspect I have to add something else to my scripts but i dont know what. For now it is jsut plain this:
echo "test"

EDIT: Ok maybe script: echo "test" is not the best example since it is true that there is no opened terminal to write to.
But same thing happens if I try to execute script that looks like this:
code ~/.i3/config
This jsut opens the i33 config file with visual studio code. Again this works when I execute it via dmenu_run that was called from existing termina but it doesen't work when executed via dmenu_run that was called via i3 keybinding mod+d

Day 14: It's in the cards (Tarot and other Cartomancy) PART 1

I've devoted a day to tarot because, like meditation, it can be a great tool for anyone on any path, as well as non-witches.
To keep this from being it's own book, I'm going to skip the history of tarot (which is interesting but easy to look up) and I'm not going to go in depth about any specific style. When I say the word tarot here, I mean specifically divination using a tarot deck with a total of 78 cards, including 22 major arcana (or "trump cards") and 56 minor arcana consisting of 4 suits (much like a deck of playing cards.)
It is, however, perfectly fine to "misuse" the word tarot to mean any form of cartomancy that involves the use of "spreads." It's not going to offend anyone (except pedants) and it can be useful to add the word "tarot" to an inquiry or search, especially when looking for a deck online.
There are three major variations of tarot deck- Rider-Waite, Tarot de Marseille, and Thoth. Most of the tarot decks available are based on the imagery of these three. There are differences, but generally they could be used interchangeably, so I'm not going to get too in depth about it. When you buy a deck, it can be helpful to know which style it is so you can be aware of how the creators meant them to be used. (You can usually find out online in stores or the official webpage, but you can also search for the differences and find out what style your deck matches. There are also versions that are unique to the deck/creator.
As I said, tarot is for everyone. There is very low risk of cultural appropriation. (Decks are often themed and some decks can be considered cultural appropriation.) There are a surprising number of myths that are nothing more than gatekeeping bs. I'm going to get into it, but the first thing to know is that you do not need anything but a tarot deck to begin doing tarot. I've make a deck from a pack of index cards, it doesn't have to be an expensive deck or anything fancy.
Which brings me to a strange myth I keep seeing lately in reference to tarot as well as other practices. Outside of specific religions, there is nothing in magic that MUST be given as a gift to "work." The best theory I've found to explain this floating garbage is that it was started as basically a "gift with membership" or "foot in the door" technique by the Hermetic Order of the Golden Dawn. There's no basis in it. Divination is about your ability to interpret symbols in context. It doesn't really matter where they came from.
Another myth is that you can't let other people touch your cards. You might not want to LET people touch them, and that's okay. It's a good idea to have boundaries about your tools and possessions. But someone touching the cards won't break them, you don't need to burn them, and if you don't mind any energy that does affect them (like love, awe, or open-minded curiosity) you don't need to cleanse them. You might choose to cleanse them after they are touched if you don't like the energy that comes from the person or anytime you feel like you need to. Just like with anything that isn't yours, please do not just touch or grab someones tarot cards without asking. It is rude.
Tarot does not require the use of elaborate spreads. They are one option of many. It's okay to use them like a "magic 8 ball" and ask yes or no questions and pull one card. You might get an answer that means "ask again later," or that indicate you should do a more elaborate spread, but you'll often get a yes or no.
Because divination, carotmancy, and tarot are about interpreting specific symbols in a specific context- there aren't TRULY any beginner (or "beginner friendly") decks. It really doesn't matter if you have a single word, a detailed image, an emoji-style simple symbol, a color, or a paragraph- you still have to interpret it. You cannot get around doing the work. If you find yourself connecting to a deck that is considered "advanced," you will still be able to read with it. If you need to look up meanings every time you use it or write down your own meanings or you realize you've gone way off from any "usual" meanings, that's okay. If it works- it doesn't matter what "level" other people have assigned to it.
There is no "One True Way" to shuffle, full, place, or read the cards of any deck. You do not even have to use all of the cards for a reading. It is okay to use only major or minor arcana if you want.
I'll mention some quirks that can happen with decks in part 2.
There are other common styles and decks designed for cartomancy.
Lenormand cartomancy (often referred to as "Lenormand tarot") was named after a famous cartomancer from the 1800s who published several works related to cartomancy. The cards and system bearing her name were created after her death. This system uses 36 cards with images of animals, objects and people. It doesn't work very well for single card spreads or less linear spreads. Each card gives context to the next.
Kipper cartomancy (also referred to as Kipper tarot) also uses 36 cards and creates very linear readings, and the imagery is not really meant to be interpreted as much as the reading is meant to basically be complete ideas. This deck is best for interpersonal affairs since the cards depict mainly people and actions.
Oracle cards are other decks of varying styles with any number of cards. There is no standard oracle deck. Some have a lot of text, some have only a card title, some are only images. Like tarot decks. you can find an oracle deck that works for you. You can use tarot spreads with oracle cards without (extra) difficulty. You can do "yes/no" single card pulls with them. If you do not want to worry about 78 cards or you want a deck personalized to you and your needs without the baggage of generally accepted meanings, an oracle deck might work better than tarot for you.
Playing cards are also a valid option. They can usually be obtained easily and inexpensively. The suits and numbers can correlate with tarot minor arcana or you might find regional meanings for playing card cartomancy. Playing cards are great for use in spells as well.
If you do not own a tarot (or other cartomancy) deck but are interested in buying one, here is what I think you should consider:
My first tarot deck ever was a very small "Tarot Nova" deck. It came in a very small box (about the size of a post-it note.) It was perfect for my needs which were mostly hanging out with the other witches and their pendulums at school. It was portable and very inexpensive at the book store checkout line in a rotating display of tiny novelty kits. I have so far lost all of my tarot cards to small children, complications from homelessness, and moving frequently as a younger adult. Now I am in a position where I don't have to think about those things. My next deck will represent my values of simplicity, intuition, and quality. My needs now are different from when I was 16 or 25. Your needs are different from 5 years ago and will be different again in 5 years. It's okay if your deck changes too.
I am just going to touch on some common quirks that you might encounter.
I really thought I'd be able to trim tarot down to a one day event, but even without talking about the history of tarot or even how-to tarot, I can't. So tomorrow will be cartomancy, continued. I'll talk about where the answers come from, what to do if your spread isn't giving you answers, and non-divination ways to use cards in witchcraft.
So today, your optional assignment is to think of a deck you would like, then look to see if a version of it exists. It might help you find a deck you like, or just demonstrate how many options are out there.
Then tell me
  1. Do you already use tarot or other cards for divination? What are some things you've noticed or learned about your personal relationship with your cards?
  2. What do you currently think you'd like to look for in a deck, if you plan to get one? (Remember that there are no wrong answers. If your main concern is that it be free- that's okay. If you just want something beautiful- that's okay. If you have a 12 point checklist, it might be a little restrictive but I'll assume you put thought into it, so that's okay too.) Or do you think you'll pass until/unless cards come into your life? Or do you think you'll pass on card divination altogether?
  3. How are your other practices going? Are you meditating regularly, adding herbs to your BoS, are you still using your BoS? How are you feeling right now? Even if you don't want to comment and check in with me, check in with yourself and make a note of where you are in this moment.
We've been going through a lot of information very quickly, thank you all so much for sticking with me so far. If you've fallen behind, don't stress. Catch up when you can. See you tomorrow!

My current goal is to turn this into a book, and perhaps repeat this type of "course" in the future. I truly believe there is no cost of admission to witchcraft and I will never ask you to buy anything (from me or otherwise.)
If you would like and are comfortably able to leave a tip, I do have CashApp, Venmo, and Paypal. (Starving artist is a lifestyle choice, but not-starving artist is great too. And no, I'm not actually starving, but I am looking at paying some money to get this project turned into a book and I've got my eye on this tarot deck...)

THE SEARCH FOR THE GREATEST SWITCH SHMUP: EPISODE 28 – Raiden V: Director’s Cut

Before I begin, I just want to remind everyone that all of my reviews can be found at my site: www.azormx.com. I tried to keep it as minimalist as possible, and it doesn't have any add or any other intrusive elements, so the content is king. Do check it out, as reviews are usually live there before I publish them elsewhere. Any way, on to the review!

The shmup genre hasn’t been a mainstream genre in a long time. To be honest, I don’t think it ever was, even during the arcade days. While we certainly don’t have a shortage of shmups, let alone new release, they usually come from smaller teams. Indies have taken it upon themselves to become a guiding light for all of us. Their creations have been nothing short of amazing! However, we don’t really have anything we could call a “AAA” shmup. We do seem to have the next closest thing: Raiden.
Developer: Moss Co.
Platform: Nintendo Switch
Release date: Jul 25, 2019
Price: $29.99
Tate: Unfortunately… no. This really needed to have TATE
Raiden V: Director’s Cut is a vertical shmup set in a fictional but real world. It claims to be the original bullet-hell, and after playing it extensively I gotta say that I agree. Raiden V features some intense air combat, coupled with giant bosses and some jaw-dropping transitions between areas.

THE GREAT INTRO CHECKLIST

Right out of the gate, what caught my attention was the intro. The best way I can put this is that it has everything great about shmups in a short video. It has a great track, it has giant enemies, it has ships and it even has pieces of lore I do not understand! Simply amazing!
Most importantly, it is a very accurate portrayal as to what you should expect from the game. Unlike other shmups, Raiden goes all out in the presentation department, with the story taking a mayor role. Another way I can put this, is that it certainly feels like a considerable effort was placed in every element of the game. Raiden V features a level of polish that very few shmups can claim to have.

WELCOME TO THE CUSTOMIZATION STATION

One of Raiden’s strength is the amount of customization you have available for your ship. At the beginning of the game, you can choose between one of 3 different ships: Azuma, Spirit of Dragon and Moulin Rouge. Each of these ships has different stats in terms of attack, defense and speed. They also have their own sub-shot which is always firing along with your main cannon.
On top of selecting a ship, you can arm yourself with 3 out of 9 different weapons. Those 9 weapons are grouped into 3 categories: Vulcan, Laser and Plasma. You can pick, or rather you must pick 1 for each category. The result is a combat style that is unique to you.
During your play throughs, you will encounter several power-up orbs. These orbs will power up each of your weapons up to 10 times! Each of these orbs can be either red, blue or purple depending on the weapon it powers up. The orbs cycle the colors, with an outer dot indicating a timer until it changes colors. This allows you to control which weapon you want to power up, giving you the flexibility to pick your own style or choose a weapon for the occasion.
The best part is that absolutely no power-ups are lost upon death! This means that you are free to retry to your heart's content and play at your own pace. Raiden won't punish you or set you up for failure with an unrecoverable situation.
I didn’t put too much attention into weapon selection at first. I figured it wouldn’t be too relevant, as I would probably just play the entire game with a single weapon, but the advanced scoring mechanics and the rank system were quick to make me second guess my decision.

ACE PILOT

At the core of Raiden V, there are 2 main systems to be aware of: your rank and your flash level. Both of them measure your combat capabilities, although in different ways. Your flash point gauge is a score multiplier that tracks how fast you defeat your enemies. By defeating enemies as soon as possible after spawning, you can earn higher multipliers to increase your flash gauge. By having quick kills, you can raise it to higher levels to increase your score. Your rank, on the other hand, only concerns itself with how many enemies you’ve defeated.
Your rank doubles as the deciding factor of which path you will be taking. Raiden features branching paths with an A, B, C or S version of each stage. Depending on your total destruction rate, you will either move up or down in rank after a stage. While I do not know the exact numbers, I believe having more than 98% destruction rate will increase your rank, 90 – 98% will keep it as is and <90% should decrease your rank. S rank stages are presumably harder than A/B/C stages, with C being the lowest.
Apart from having a higher score and challenging yourself with the difficulty, the importance of S rank is getting the true ending. In order to truly watch the ending of the game, you need to reach the final stage on S rank using a single credit. You also need to power up your 3 weapons to level 10. Once you meet those conditions, you will be able to challenge the final boss. Alternatively, you could just fulfill the level 10 weapons condition to fight the true final boss.

THE BEST CHEERLEADER

A new addition to Raiden V is the cheer system. By accomplishing certain in-game milestones like a certain number of enemies destroyed, you will get an achievement. These achievements are broadcasted to any players connected to the leaderboards. They can then “cheer” on your achievement to increase your cheer gauge. This goes both ways, as you can also cheer the achievements of your fellow Raiden players.
Once the cheer gauge is full, you can unleash it to clear the screen and gain a drastically stronger sub-shot. Think of it as a devastating bomb, only more devastating and easier to fill. It clears screens and decimates even the bosses.
Perhaps many people won’t think too much of it, but I found it really interesting to know that there’s someone on the other side celebrating my achievements. Likewise, there were times where I left my game on pause to do other stuff, but held on to my controller to provide support for my comrades.

SWIFT DESTRUCTION

Everything I’ve mentioned before plays out in the general strategy of the game. Assuming you want to get the best results, you need to know where to hit and how to hit hard. For the untrained eye, most shmups just look like games where you fire away with complete disregard and hope the enemy dies. This is definitely not the case in Raiden.
In order to succeed, you must be able to find your rhythm and read the stage. Learn the enemy formations and strategize the quickest kills. Be there before the enemy arrives and take them down before they realize what hit them. If you want to face the true final boss, then you must also learn to juggle your weapons and find the moments to upgrade them. Maxing a weapon and then switching is a recipe for disaster, as you don’t want to be on the later stages with a level one weapon and risk your flash level or destruction rate. With so many weapons and ship types, your strategy to succeed will be unique to you!

LORE GALORE

One of the main selling points, at least per the game itself, is the story. Raiden V features an extensive story that is fully voiced and occurs as you play the game. This story elements come as the prologue and epilogue scenes, as well as all the events happening mid stage.
As you fly your way to the levels, characters will be advancing the story by having conversations and narrating the current events. The dialogue is available on one of the gadgets located on the right side of the screen. You can read anything you might have missed and even pause to read the on-screen log of events (up to a certain number of events, as the log scrolls to open way for new text).
As for my opinion of the story, I have absolutely no idea of what happened during the game. I played my fair share of runs, but I found it next to impossible to focus on the dialogue while trying my hardest to survive. The voice acting would have been my saving grace, but I found the sound mixing to be the opposite of ideal for listening to dialogue. I even tried lowering the sound effects and BGM to see if I could focus on dialogue to no avail.
The text is also incredibly small when playing on docked mode. It gets even worse when playing handheld.

THE WORST CHEERLEADER

Out of all the voices, Eshiria’s was the one who got on my nerves the most at the beginning. Other than having her role as navigator on the plot, she also critiques your gameplay. In-between stage scenes, she will provide commentary describing your gameplay. She will be quick to point out if you did well, but also if you did poorly. On my early runs, when I was still learning, it would tilt me to listen to her complaining to me about stats I did not understand.
And perhaps, a huge part of my problems was a lack of understanding of the game mechanics. I listened to her complain about my destruction rate without knowing it was about my rank. She also complained about destruction speed without me knowing it was about the flash point.
The problem is that the game never bothered explaining any of its mechanics to me. I really looked around for some sort of tutorial to no avail. I had to resort to 3rd party resources. While that isn’t uncommon, I really don’t like games with obscure mechanics that can’t be discerned in-game.
Once I got better and consistently reach the S levels, I finally started to value her advice. Of course, I wouldn’t count on everyone reaching the same enlightenment as I did. In my opinion, her comments would more often than not add insult to injury. Once again, it’s not really the commentary, it’s the fact that none of what she said made practical sense until I started digging on the wiki.

GADGETS AND THE SCREEN REAL ESTATE

Perhaps the worst omission from Raiden V is the lack of a TATE mode. Vertical shooters don’t really have an excuse to do this, with the existence of add-ons like the flip grip or rotating monitors. Instead, Raiden decided to make the most out of the free space and add several gadgets.
In standard fashion, these gadgets will keep your stats like score, flash level, the dialogue and even hi-score statistics. Your left gadget can even be cycled between the score chart and cheer notification, in-game tips and global statistics. Out of those, the tips are definitely the winners. They do give some important advice, such as staying on top of the guns of the first boss to avoid damage.

NOT A FRIENDLY NEIGHBORHOOD

Every stage is divided into smaller scenes. These scenes serve as a way to catch your breath and tally your score. There’s even a nifty “restart scene” option that allows you to replay a scene. Choosing to restart will deny you the option to upload your score to the leaderboard, but serves as a great way to practice or even “fix” a run to so can get to the true ending.
Every once in a while, the action will pan out and open the way to a bigger stage, with you looking smaller in comparison. I admire the grandioseness of the resulting scenes, but they were also quite impractical. Think about your weapons, the destruction rate and the flash gauge. An extended stage means longer travel distances from side to side. Having a bigger stage means you move slower, which reduces the pacing of the game to a crawl. Reaching enemies quickly becomes a struggle. Worst yet, I’ve counted times where it took me whopping 5 seconds to go from side to side of the stage.

THE OG BULLET HELL

Despite all the fun of blasting enemies quickly to gain flash levels, I gotta say that I found the combat, specifically the bullets, to be lacking in grace. For a game that’s the original bullet hell, most enemy volleys feel like bullet showers. There’s no finesse in them, just a bunch of bullets moving towards you. Dodging them isn’t fun, it’s survival. The problem only gets worse in higher difficulties where the bullets just go faster.
Not all patterns are as bad though. While the vast majority will be just a bunch on increasingly faster bullets thrown at you, some exceptional patterns will show from time to time. As a result, fights tend to be very hit or miss, with both hits and misses being on their respective extremes.
What certainly doesn’t help is that the bullets are very hard to see. As pretty as the backgrounds might be, they are very busy and the quick motion makes them into a blur. Bullets don’t have their characteristic outlines or color palettes to become distinguishable. Some even blend with your own vulcan. The result is a lot of cheap kills caused by intentional obfuscation. It this was their intention, then perhaps I’m being too harsh, but you know visibility is usually one of my pet peeves in shmups.

REPLAYABILITY AND LONGEVITY

As far as game length goes, I consider Raiden V to be one of the longer ones. I was surprised after my first run of the game, as it took me 50+ minutes to complete the campaign. Usually, my baseline for shmups is around half an hour, which made this one almost twice as long. While I’m not fond of longer campaigns, I know a lot of people would certainly be glad to know there is plenty of content.
Of course, playing through the campaign isn’t enough to view the entire game. If you recall, most stages have 4 versions of themselves. Those versions are separated by the ranks: S/A/B/C. This means you would need at least 4 runs to see everything the game has to offer. There’s also 6 different endings to uncover.
Also new to the Director’s Cut edition are 2 bonus levels. These level are slightly different from your typical levels. The bonus missions will challenge you to fight a new boss ir oder to obtain medals. Dealing damage will detach the medals from the boss, allowing you to catch them. Gather enough medals and you will advance to the next phase. Higher medals mean higher ranking. Taking damage will take medals away from you, so surviving continues to be a priority.
Lastly, there is a new boss mission mode that allow you to play “boss rush” missions. These missions have certain conditions, like using a specific weapon or fighting at a specific HP level. The targets are usually 1-3 bosses. Boss mission is a very fun arcadey mode for those who enjoyed the boss fights and want more of them.

SOUND EXCELLENCE

If there’s a factor that merits my highest praise is the sound department. Simply put, the OST is fantastic. The track length syncs perfectly with the stages, and it always fits the mood. I just couldn’t get enough of the OST, and listening to it while writing this review was the recipe for a perfect Sunday! I also got some good coffee that would make the captain proud.
For all the praise the music gets from me, it still is dragged down by the terrible sound mixing. Similarly to the voice acting, I tried to mess with the sound settings to increase the volume and reduce the sound effects, but it still wasn’t enough. The tracks were great but I struggled to listen to them amidst all the explosions. The calm moments were great, as they let me listen to the songs in peace.

LAST WORDS

Raiden is a master class in shmup design for the wrong reasons. Its high points perfectly illustrate how shmups should look and feel. The low points also show what you should NOT do when creating a shmup game. Despite all of this, it all comes down to how fun a game is.
Raiden V is a very fun game. It isn’t different, but it’s certainly very polished. I delivers some levels of quality that are notably absent in the majority of the games. As a concept, I feel like it serves as an example of how current gen shmups should be. The execution fell flat in some regards, but as a whole I was satisfied with the time I spent with the game. It does come with a hefty price tag, so my advice is to check this game out when you find a decent sale. I got mine at -70%.

glimpse into the future of Roblox

Our vision to bring the world together through play has never been more relevant than it is now. As our founder and CEO, David Baszucki (a.k.a. Builderman), mentioned in his keynote, more and more people are using Roblox to stay connected with their friends and loved ones. He hinted at a future where, with our automatic machine translation technology, Roblox will one day act as a universal translator, enabling people from different cultures and backgrounds to connect and learn from each other.
During his keynote, Builderman also elaborated upon our vision to build the Metaverse; the future of avatar creation on the platform (infinitely customizable avatars that allow any body, any clothing, and any animation to come together seamlessly); more personalized game discovery; and simulating large social gatherings (like concerts, graduations, conferences, etc.) with tens of thousands of participants all in one server. We’re still very early on in this journey, but if these past five months have shown us anything, it’s clear that there is a growing need for human co-experience platforms like Roblox that allow people to play, create, learn, work, and share experiences together in a safe, civil 3D immersive space.
Up next, our VP of Developer Relations, Matt Curtis (a.k.a. m4rrh3w), shared an update on all the things we’re doing to continue empowering developers to create innovative and exciting content through collaboration, support, and expertise. He also highlighted some of the impressive milestones our creator community has achieved since last year’s RDC. Here are a few key takeaways:
And lastly, our VP of Engineering, Technology, Adam Miller (a.k.a. rbadam), unveiled a myriad of cool and upcoming features developers will someday be able to sink their teeth into. We saw a glimpse of procedural skies, skinned meshes, more high-quality materials, new terrain types, more fonts in Studio, a new asset type for in-game videos, haptic feedback on mobile, real-time CSG operations, and many more awesome tools that will unlock the potential for even bigger, more immersive experiences on Roblox.

Vibin’

Despite the virtual setting, RDC just wouldn’t have been the same without any fun party activities and networking opportunities. So, we invited special guests DJ Hyper Potions and cyber mentalist Colin Cloud for some truly awesome, truly mind-bending entertainment. Yoga instructor Erin Gilmore also swung by to inspire attendees to get out of their chair and get their body moving. And of course, we even had virtual rooms dedicated to karaoke and head-to-head social games, like trivia and Pictionary.
Over on the networking side, Team Adopt Me, Red Manta, StyLiS Studios, and Summit Studios hosted a virtual booth for attendees to ask questions, submit resumes, and more. We also had a networking session where three participants would be randomly grouped together to get to know each other.

What does Roblox mean to you?

We all know how talented the Roblox community is from your creations. We’ve heard plenty of stories over the years about how Roblox has touched your lives, how you’ve made friendships, learned new skills, or simply found a place where you can be yourself. We wanted to hear more. So, we asked attendees: What does Roblox mean to you? How has Roblox connected you? How has Roblox changed your life? Then, over the course of RDC, we incorporated your responses into this awesome mural.

Knowledge is power

This year’s breakout sessions included presentations from Roblox developers and staff members on the latest game development strategies, a deep dive into the Roblox engine, learning how to animate with Blender, tools for working together in teams, building performant game worlds, and the new Creator Dashboard. Dr. Michael Rich, Associate Professor at Harvard Medical School and Physician at Boston Children’s Hospital, also led attendees through a discussion on mental health and how to best take care of you and your friends’ emotional well-being, especially now during these challenging times.

Improving Simulation and Performance with an Advanced Physics Solver

August

05, 2020

by chefdeletat
PRODUCT & TECH
📷In mid-2015, Roblox unveiled a major upgrade to its physics engine: the Projected Gauss-Seidel (PGS) physics solver. For the first year, the new solver was optional and provided improved fidelity and greater performance compared to the previously used spring solver.
In 2016, we added support for a diverse set of new physics constraints, incentivizing developers to migrate to the new solver and extending the creative capabilities of the physics engine. Any new places used the PGS solver by default, with the option of reverting back to the classic solver.
We ironed out some stability issues associated with high mass differences and complex mechanisms by the introduction of the hybrid LDL-PGS solver in mid-2018. This made the old solver obsolete, and it was completely disabled in 2019, automatically migrating all places to the PGS.
In 2019, the performance was further improved using multi-threading that splits the simulation into jobs consisting of connected islands of simulating parts. We still had performance issues related to the LDL that we finally resolved in early 2020.
The physics engine is still being improved and optimized for performance, and we plan on adding new features for the foreseeable future.

Implementing the Laws of Physics

📷
The main objective of a physics engine is to simulate the motion of bodies in a virtual environment. In our physics engine, we care about bodies that are rigid, that collide and have constraints with each other.
A physics engine is organized into two phases: collision detection and solving. Collision detection finds intersections between geometries associated with the rigid bodies, generating appropriate collision information such as collision points, normals and penetration depths. Then a solver updates the motion of rigid bodies under the influence of the collisions that were detected and constraints that were provided by the user.
📷
The motion is the result of the solver interpreting the laws of physics, such as conservation of energy and momentum. But doing this 100% accurately is prohibitively expensive, and the trick to simulating it in real-time is to approximate to increase performance, as long as the result is physically realistic. As long as the basic laws of motion are maintained within a reasonable tolerance, this tradeoff is completely acceptable for a computer game simulation.

Taking Small Steps

The main idea of the physics engine is to discretize the motion using time-stepping. The equations of motion of constrained and unconstrained rigid bodies are very difficult to integrate directly and accurately. The discretization subdivides the motion into small time increments, where the equations are simplified and linearized making it possible to solve them approximately. This means that during each time step the motion of the relevant parts of rigid bodies that are involved in a constraint is linearly approximated.
📷📷
Although a linearized problem is easier to solve, it produces drift in a simulation containing non-linear behaviors, like rotational motion. Later we’ll see mitigation methods that help reduce the drift and make the simulation more plausible.

Solving

📷
Having linearized the equations of motion for a time step, we end up needing to solve a linear system or linear complementarity problem (LCP). These systems can be arbitrarily large and can still be quite expensive to solve exactly. Again the trick is to find an approximate solution using a faster method. A modern method to approximately solve an LCP with good convergence properties is the Projected Gauss-Seidel (PGS). It is an iterative method, meaning that with each iteration the approximate solution is brought closer to the true solution, and its final accuracy depends on the number of iterations.
📷
This animation shows how a PGS solver changes the positions of the bodies at each step of the iteration process, the objective being to find the positions that respect the ball and socket constraints while preserving the center of mass at each step (this is a type of positional solver used by the IK dragger). Although this example has a simple analytical solution, it’s a good demonstration of the idea behind the PGS. At each step, the solver fixes one of the constraints and lets the other be violated. After a few iterations, the bodies are very close to their correct positions. A characteristic of this method is how some rigid bodies seem to vibrate around their final position, especially when coupling interactions with heavier bodies. If we don’t do enough iterations, the yellow part might be left in a visibly invalid state where one of its two constraints is dramatically violated. This is called the high mass ratio problem, and it has been the bane of physics engines as it causes instabilities and explosions. If we do too many iterations, the solver becomes too slow, if we don’t it becomes unstable. Balancing the two sides has been a painful and long process.

Mitigation Strategies

📷A solver has two major sources of inaccuracies: time-stepping and iterative solving (there is also floating point drift but it’s minor compared to the first two). These inaccuracies introduce errors in the simulation causing it to drift from the correct path. Some of this drift is tolerable like slightly different velocities or energy loss, but some are not like instabilities, large energy gains or dislocated constraints.
Therefore a lot of the complexity in the solver comes from the implementation of methods to minimize the impact of computational inaccuracies. Our final implementation uses some traditional and some novel mitigation strategies:
  1. Warm starting: starting with the solution from a previous time-step to increase the convergence rate of the iterative solver
  2. Post-stabilization: reprojecting the system back to the constraint manifold to prevent constraint drift
  3. Regularization: adding compliance to the constraints ensuring a solution exists and is unique
  4. Pre-conditioning: using an exact solution to a linear subsystem, improving the stability of complex mechanisms
Strategies 1, 2 and 3 are pretty traditional, but 3 has been improved and perfected by us. Also, although 4 is not unheard of, we haven’t seen any practical implementation of it. We use an original factorization method for large sparse constraint matrices and a new efficient way of combining it with the PGS. The resulting implementation is only slightly slower compared to pure PGS but ensures that the linear system coming from equality constraints is solved exactly. Consequently, the equality constraints suffer only from drift coming from the time discretization. Details on our methods are contained in my GDC 2020 presentation. Currently, we are investigating direct methods applied to inequality constraints and collisions.

Getting More Details

Traditionally there are two mathematical models for articulated mechanisms: there are reduced coordinate methods spearheaded by Featherstone, that parametrize the degrees of freedom at each joint, and there are full coordinate methods that use a Lagrangian formulation.
We use the second formulation as it is less restrictive and requires much simpler mathematics and implementation.
The Roblox engine uses analytical methods to compute the dynamic response of constraints, as opposed to penalty methods that were used before. Analytics methods were initially introduced in Baraff 1989, where they are used to treat both equality and non-equality constraints in a consistent manner. Baraff observed that the contact model can be formulated using quadratic programming, and he provided a heuristic solution method (which is not the method we use in our solver).
Instead of using force-based formulation, we use an impulse-based formulation in velocity space, originally introduced by Mirtich-Canny 1995 and further improved by Stewart-Trinkle 1996, which unifies the treatment of different contact types and guarantees the existence of a solution for contacts with friction. At each timestep, the constraints and collisions are maintained by applying instantaneous changes in velocities due to constraint impulses. An excellent explanation of why impulse-based simulation is superior is contained in the GDC presentation of Catto 2014.
The frictionless contacts are modeled using a linear complementarity problem (LCP) as described in Baraff 1994. Friction is added as a non-linear projection onto the friction cone, interleaved with the iterations of the Projected Gauss-Seidel.
The numerical drift that introduces positional errors in the constraints is resolved using a post-stabilization technique using pseudo-velocities introduced by Cline-Pai 2003. It involves solving a second LCP in the position space, which projects the system back to the constraint manifold.
The LCPs are solved using a PGS / Impulse Solver popularized by Catto 2005 (also see Catto 2009). This method is iterative and considers each individual constraints in sequence and resolves it independently. Over many iterations, and in ideal conditions, the system converges to a global solution.
Additionally, high mass ratio issues in equality constraints are ironed out by preconditioning the PGS using the sparse LDL decomposition of the constraint matrix of equality constraints. Dense submatrices of the constraint matrix are sparsified using a method we call Body Splitting. This is similar to the LDL decomposition used in Baraff 1996, but allows more general mechanical systems, and solves the system in constraint space. For more information, you can see my GDC 2020 presentation.
The architecture of our solver follows the idea of Guendelman-Bridson-Fedkiw, where the velocity and position stepping are separated by the constraint resolution. Our time sequencing is:
  1. Advance velocities
  2. Constraint resolution in velocity space and position space
  3. Advance positions
This scheme has the advantage of integrating only valid velocities, and limiting latency in external force application but allowing a small amount of perceived constraint violation due to numerical drift.
An excellent reference for rigid body simulation is the book Erleben 2005 that was recently made freely available. You can find online lectures about physics-based animation, a blog by Nilson Souto on building a physics engine, a very good GDC presentation by Erin Catto on modern solver methods, and forums like the Bullet Physics Forum and GameDev which are excellent places to ask questions.

In Conclusion

The field of game physics simulation presents many interesting problems that are both exciting and challenging. There are opportunities to learn a substantial amount of cool mathematics and physics and to use modern optimizations techniques. It’s an area of game development that tightly marries mathematics, physics and software engineering.
Even if Roblox has a good rigid body physics engine, there are areas where it can be improved and optimized. Also, we are working on exciting new projects like fracturing, deformation, softbody, cloth, aerodynamics and water simulation.

Using Clang to Minimize Global Variable Use

July

23, 2020

by RandomTruffle
PRODUCT & TECH
Every non-trivial program has at least some amount of global state, but too much can be a bad thing. In C++ (which constitutes close to 100% of Roblox’s engine code) this global state is initialized before main() and destroyed after returning from main(), and this happens in a mostly non-deterministic order. In addition to leading to confusing startup and shutdown semantics that are difficult to reason about (or change), it can also lead to severe instability.
Roblox code also creates a lot of long-running detached threads (threads which are never joined and just run until they decide to stop, which might be never). These two things together have a very serious negative interaction on shutdown, because long-running threads continue accessing the global state that is being destroyed. This can lead to elevated crash rates, test suite flakiness, and just general instability.
The first step to digging yourself out of a mess like this is to understand the extent of the problem, so in this post I’m going to talk about one technique you can use to gain visibility into your global startup flow. I’m also going to discuss how we are using this to improve stability across the entire Roblox game engine platform by decreasing our use of global variables.

Introducing -finstrument-functions

Nothing excites me more than learning about a new obscure compiler option that I’ve never had a use for before, so I was pretty happy when a colleague pointed me to this option in the Clang Command Line Reference. I’d never used it before, but it sounded very cool. The idea being that if we could get the compiler to tell us every time it entered and exited a function, we could filter this information through a symbolizer of some kind and generate a report of functions that a) occur before main(), and b) are the very first function in the call-stack (indicating it’s a global).
Unfortunately, the documentation basically just tells you that the option exists with no mention of how to use it or if it even actually does what it sounds like it does. There’s also two different options that sound similar to each other (-finstrument-functions and -finstrument-functions-after-inlining), and I still wasn’t entirely sure what the difference was. So I decided to throw up a quick sample on godbolt to see what happened, which you can see here. Note there are two assembly outputs for the same source listing. One uses the first option and the other uses the second option, and we can compare the assembly output to understand the differences. We can gather a few takeaways from this sample:
  1. The compiler is injecting calls to __cyg_profile_func_enter and __cyg_profile_func_exit inside of every function, inline or not.
  2. The only difference between the two options occurs at the call-site of an inline function.
  3. With -finstrument-functions, the instrumentation for the inlined function is inserted at the call-site, whereas with -finstrument-functions-after-inlining we only have instrumentation for the outer function. This means that when using-finstrument-functions-after-inlining you won’t be able to determine which functions are inlined and where.
Of course, this sounds exactly like what the documentation said it did, but sometimes you just need to look under the hood to convince yourself.
To put all of this another way, if we want to know about calls to inline functions in this trace we need to use -finstrument-functions because otherwise their instrumentation is silently removed by the compiler. Sadly, I was never able to get -finstrument-functions to work on a real example. I would always end up with linker errors deep in the Standard C++ Library which I was unable to figure out. My best guess is that inlining is often a heuristic, and this can somehow lead to subtle ODR (one-definition rule) violations when the optimizer makes different inlining decisions from different translation units. Luckily global constructors (which is what we care about) cannot possibly be inlined anyway, so this wasn’t a problem.
I suppose I should also mention that I still got tons of linker errors with -finstrument-functions-after-inlining as well, but I did figure those out. As best as I can tell, this option seems to imply –whole-archive linker semantics. Discussion of –whole-archive is outside the scope of this blog post, but suffice it to say that I fixed it by using linker groups (e.g. -Wl,–start-group and -Wl,–end-group) on the compiler command line. I was a bit surprised that we didn’t get these same linker errors without this option and still don’t totally understand why. If you happen to know why this option would change linker semantics, please let me know in the comments!

Implementing the Callback Hooks

If you’re astute, you may be wondering what in the world __cyg_profile_func_enter and __cyg_profile_func_exit are and why the program is even successfully linking in the first without giving undefined symbol reference errors, since the compiler is apparently trying to call some function we’ve never defined. Luckily, there are some options that allow us to see inside the linker’s algorithm so we can find out where it’s getting this symbol from to begin with. Specifically, -y should tell us how the linker is resolving . We’ll try it with a dummy program first and a symbol that we’ve defined ourselves, then we’ll try it with __cyg_profile_func_enter .
[email protected]:~/src/sandbox$ cat instr.cpp int main() {} [email protected]:~/src/sandbox$ clang++-9 -fuse-ld=lld -Wl,-y -Wl,main instr.cpp /usbin/../lib/gcc/x86_64-linux-gnu/crt1.o: reference to main /tmp/instr-5b6c60.o: definition of main
No surprises here. The C Runtime Library references main(), and our object file defines it. Now let’s see what happens with __cyg_profile_func_enter and -finstrument-functions-after-inlining.
[email protected]:~/src/sandbox$ clang++-9 -fuse-ld=lld -finstrument-functions-after-inlining -Wl,-y -Wl,__cyg_profile_func_enter instr.cpp /tmp/instr-8157b3.o: reference to __cyg_profile_func_enter /lib/x86_64-linux-gnu/libc.so.6: shared definition of __cyg_profile_func_enter
Now, we see that libc provides the definition, and our object file references it. Linking works a bit differently on Unix-y platforms than it does on Windows, but basically this means that if we define this function ourselves in our cpp file, the linker will just automatically prefer it over the shared library version. Working godbolt link without runtime output is here. So now you can kind of see where this is going, however there are still a couple of problems left to solve.
  1. We don’t want to do this for a full run of the program. We want to stop as soon as we reach main.
  2. We need a way to symbolize this trace.
The first problem is easy to solve. All we need to do is compare the address of the function being called to the address of main, and set a flag indicating we should stop tracing henceforth. (Note that taking the address of main is undefined behavior[1], but for our purposes it gets the job done, and we aren’t shipping this code, so ¯\_(ツ)_/¯). The second problem probably deserves a little more discussion though.

Symbolizing the Traces

In order to symbolize these traces, we need two things. First, we need to store the trace somewhere on persistent storage. We can’t expect to symbolize in real time with any kind of reasonable performance. You can write some C code to save the trace to some magic filename, or you can do what I did and just write it to stderr (this way you can pipe stderr to some file when you run it).
Second, and perhaps more importantly, for every address we need to write out the full path to the module the address belongs to. Your program loads many shared libraries, and in order to translate an address into a symbol, we have to know which shared library or executable the address actually belongs to. In addition, we have to be careful to write out the address of the symbol in the file on disk. When your program is running, the operating system could have loaded it anywhere in memory. And if we’re going to symbolize it after the fact we need to make sure we can still reference it after the information about where it was loaded in memory is lost. The linux function dladdr() gives us both pieces of information we need. A working godbolt sample with the exact implementation of our instrumentation hooks as they appear in our codebase can be found here.

Putting it All Together

Now that we have a file in this format saved on disk, all we need to do is symbolize the addresses. addr2line is one option, but I went with llvm-symbolizer as I find it more robust. I wrote a Python script to parse the file and symbolize each address, then print it in the same “visual” hierarchical format that the original output file is in. There are various options for filtering the resulting symbol list so that you can clean up the output to include only things that are interesting for your case. For example, I filtered out any globals that have boost:: in their name, because I can’t exactly go rewrite boost to not use global variables.
The script isn’t as simple as you would think, because simply crawling each line and symbolizing it would be unacceptably slow (when I tried this, it took over 2 hours before I finally killed the process). This is because the same address might appear thousands of times, and there’s no reason to run llvm-symbolizer against the same address multiple times. So there’s a lot of smarts in there to pre-process the address list and eliminate duplicates. I won’t discuss the implementation in more detail because it isn’t super interesting. But I’ll do even better and provide the source!
So after all of this, we can run any one of our internal targets to get the call tree, run it through the script, and then get output like this (actual output from a Roblox process, source file information removed):
excluded_symbols = [‘.\boost.*’]* excluded_modules = [‘/usr.\’]* /uslib/x86_64-linux-gnu/libLLVM-9.so.1: 140 unique addresses InterestingRobloxProcess: 38928 unique addresses /uslib/x86_64-linux-gnu/libstdc++.so.6: 1 unique addresses /uslib/x86_64-linux-gnu/libc++.so.1: 3 unique addresses Printing call tree with depth 2 for 29276 global variables. __cxx_global_var_init.5 (InterestingFile1.cpp:418:22) RBX::InterestingRobloxClass2::InterestingRobloxClass2() (InterestingFile2.cpp.:415:0) __cxx_global_var_init.19 (InterestingFile2.cpp:183:34) (anonymous namespace)::InterestingRobloxClass2::InterestingRobloxClass2() (InterestingFile2.cpp:171:0) __cxx_global_var_init.274 (InterestingFile3.cpp:2364:33) RBX::InterestingRobloxClass3::InterestingRobloxClass3()
So there you have it: the first half of the battle is over. I can run this script on every platform, compare results to understand what order our globals are actually initialized in in practice, then slowly migrate this code out of global initializers and into main where it can be deterministic and explicit.

Future Work

It occurred to me sometime after implementing this that we could make a general purpose profiling hook that exposed some public symbols (dllexport’ed if you speak Windows), and allowed a plugin module to hook into this dynamically. This plugin module could filter addresses using whatever arbitrary logic that it was interested in. One interesting use case I came up for this is that it could look up the debug information, check if the current address maps to the constructor of a function local static, and write out the address if so. This effectively allows us to gain a deeper understanding of the order in which our lazy statics are initialized. The possibilities are endless here.
