SteamOS does not work right on most hardware last I heard. They have specific stuff in there for the exact devices they do support (which are only two I think, SteamDeck and another one of these handhelds). It doesn't have all drivers for other hardware and there are even tweaks for the AMD chips that are in those things.

I mean it has to be the load output, how else would that work. In order to make a circuit, it needs to be live - switch - lamp - neutral. If you just had live and neutral, the circuit would be live - switch - neutral, which I guess would make a funny let's blow the fuse prank switch or something.

I just checked GOG and Humble, and there's definitely things on sale on GOG that aren't on Steam, whereas the stuff on Humble seems to all be discounted on Steam with the exact same price.

It seems unreasonable to complain about (free and unlimited I think) steam keys given to the publisher come with strings attached, but these steam keys funnel people back onto steam to play the games, and are therefore preserving of steams monopoly position. I just can't imagine any court would order Valve to give away keys both for free and with zero strings attached to the publisher, they clearly provide a service here. So I guess Valve could drop the strings and just sell the keys to the publisher and that might be less abusive idk. Certainly would incentivize the publishers to try to sell the games w/o steam keys because they make more money that way.

Btw I just googled USB power management, and on Linux the default USB "autosuspend" seems to be 2 seconds. So it going into power safe mode after half an hour seems unlikely.

Idk for sure, but this theory seems far-fetched to me. Why would it put a gamepad to sleep at all? Why would putting the gamepad HID device to sleep affect the keyboard HID device? Why wouldn't the same thing happen on Windows?

Btw, just for my curiosity, what extra feature does this keyboard have that might make it show up as gamepad as well? Does it have an analog stick on it or what's going on here?

[–] trompete@hexbear.net 3 points 1 week ago

I don't think so, it wouldn't even work if it wasn't recognized as keyboard. It probably is recognized as both a keyboard and a gamepad at the same time. Physical USB devices can (and frequently do) present as multiple devices to the host. For example, a keyboard with a scroll wheel will look like be both a keyboard and a mouse.

Idk, seems like the device (why is it a identifed as a gamepad?) doesn't respond. I guess in theory it could be the cable/connection, but I assume the thing worked fine in windows? Maybe worth trying to change the cable if that's possible anyway.

I really doubt that the Linux HID or USB drivers are actually at fault/bugged here, they work with thousands of different similar devices totally fine. Maybe that's something that might be fixed by a firmware update?

For a workaround, you might try usbreset. You could (say) write a script that either runs every 15 minutes as a cronjob, or it looks at the logs and triggers automatically when it sees these relevant errors or something like that.

For your keyboard problem, try looking at the kernel logs, which you can see by running dmesg. Congratulations for having an exotic af problem I didn't even know could happen.

I don't have high hopes you can fix this honestly, keyboards are like the most standard hardware using the most generic driver, which means your keyboard somehow differs from all other keyboards in some subtle way, and Linux driver just happens to trigger this problem while the Windows driver doesn't. What you could probably do is a workaround, like resetting the USB connection or something like that every so often.

What's separating isn't the felt, it's the rubber separating from the cork. Do you think that would work? I have something like that for repairing bicycle tubes somewhere I think. I'm skeptical though honestly that it would stick to the cork.

I tried to figure out what was going on because I was also confused. Apparently Trump said something along the lines of NATO did nothing for the US, and now eurolibs are posting pictures of alive and dead euro soldiers doing the US's bidding/dying with the "doing nothing for the US" title. The point is supposed to be to prove Trump wrong.

They do not understand that they're implicating themselves in crimes. They also do not understand that being an imperial dog/sacrifice begging for an "attaboy" is not a good look.

Ok thanks, I looked at glue specifically marketed for shoes, it's too expensive. These shoes were like 15 €, I'm not buying glue for 10.

School type glue might work (seems to be water-soluble but these are inside shoes), but I don't have any and since I'm going to have to buy something anyway, I'm going to go with "power" all-purpose type glue I think, the description seems to indicate it works on the materials and should remain flexible, and you can buy it in the shops for a couple of euros.

 

Scaling up a recipe for a massive gathering is a common holiday practice in my Italian American family. I tried showing Copilot a recipe for stuffed mushrooms from Sip and Feast. It acknowledged that to go from a serving size of six to 14 would require multiplying each ingredient by about 2.3 times, but it usually only did a couple calculations before expecting me to do the rest or trying to move on to another topic by asking me a question. When it noticed the site had options for scaling up the recipe, it mistook the “2x” and “3x” buttons for plus and minus ones that would let me dial in exactly 14 servings, and kept insisting that’s what those buttons are for. They aren’t. Then, as a last-ditch effort, I asked it to just calculate each ingredient and spell it out for me in a document. Copilot told me it would, and then did nothing.

 

I sometimes accidentally drag tabs rather than click them (touchpad sucks). I already have an extension that prevents them opening as separate windows. But recently new interesting things started happening: Sometimes they "group" together, I have no idea what the point of it is or how to undo that. Just now one of my tabs turned into a mini icon version???

 

Can't find the bloody thing.

It's just a line, black on white, segmented by round checkpoints. The line does a little angle at the checkpoints, but that's purely a visual thing. You can move left or right on it, that's all the possible inputs. You got HP and XP and levels. Totally automatic "random encounter" battles occur. There is no actual battle. When you run into a random encounter, the only thing that happens is that your XP gets higher, and your HP gets lower; there's not even an animation, just the XP and HP bars on screen change randomly.

The strategy of the game is to "grind" around the checkpoints, by moving left and right across them repeatedly, until you have leveled up enough to be able to make it to the next checkpoint.

It's some (J)RPG parody, making fun of the exponential XP grind mechanics of those games. I cannot remember what it's called and I'd like to show it to someone.

 

I probably spent somewhere between 100-200€ on EU4 back in the day over a couple of years. Still missing half the DLC. Still can't play any African nation without all my troops and advisors looking like Prussians. Still don't have access to some of the special mission trees and mechanics needed to do an interesting playthrough of many nations.

They apparently want another 212€ for me to get the full game, or pay a subscription of 8€/month.

Fuck them please pirate their games or don't play them at all.

 

I'm not high right now I swear I just had this thought going through my head for a while.

Imagine you had an Eve online (never played) style space game. There are 1000 servers, organized in a grid 10x10x10. Each server is simulating a region of space corresponding to their grid position, and connected via a network link only to the servers right next to it, so as to facilitate traveling between them.

The game is populated by a bunch of bots flying around shooting each other or whatever they're doing. If too many bots happen to be on the same server, it gets overwhelmed, everything on this one specific server slows down to slideshow levels.

I posit that, over time, the bots would tend to get stuck in this laggy region of space. If they fly around randomly, they'd encounter the laggy region of space eventually, and it would take them a lot longer to get out again.

Furthermore, the neighboring servers might also slow down, to a lesser degree, because they have to wait for the laggy server which is unable to respond quickly when handing over bots.

The observable result would be (a) clumping, like how matter clumps together in the universe due to gravity, and (b) time would seem to slow down in the clumped up area, like it does in the theory of relativity.

(a) At a sufficiently large scale, like trillions of servers and bots, this might look like a large scale attracting force. I can even imagine that two large bots swarms, flying past each other, might get stuck more towards their common center point, effectively creating a kind of orbital mechanic. Though maybe not, you'd have to simulate this to see if you could make this happen.

(b) The bots in the clumped up area, being bots simulated by the overwhelmed server, would not notice that time has slowed locally. But if you had two bots, one flies around the empty parts of space, while the other flies into the clump and then comes back out, it would seem like more time has passed for the bot that was in empty space the whole time.

Ice cream theory (hexbear.net)
submitted 8 months ago* (last edited 8 months ago) by trompete@hexbear.net to c/food@hexbear.net
 

I just bought an ice cream machine with a compressor for half price. I thought it would be easy (it isn't) but I am nerding out.

I will explain to you all, to my best understanding, some theory about frozen deserts.

First, about ice formation: Imagine some water-ice mixture. Liquid H₂O molecules will, with some probability pertaining to their low kinetic energy and being next an ice crystal, join the ice crystals, making the ice crystal grow. At the same time, water molecules on the surface of the ice crystal, will, with some probability related to their kinetic energy, break loose of the crystal structure and join the liquid water.

If more molecules go from liquid to ice, more ice will form. If more molecules go from ice to liquid, the ice melts. What effect dominates depends on the average kinetic energy of the water molecules aka the temperature. Above 0 °C, more ice melts than freezes onto crystals; below, more freezes than melts.

Now, if, instead of pure water, you dissolve sugar (or salt or ethanol or whatever) into the water, that will make it less likely for liquid water molecules to join the ice crystals, because the sugar is in the way of the water molecules wanting to join the ice. It makes the liquid-to-solid transition less common, less probable, because there are just less liquid water molecules next to the ice surface. Because the sugar doesn't join the ice crystals itself, the ice is is just pure water, and the opposite ice-to-liquid transition is not affected by the sugar.

So, in a sugar-in-water solution, for the same temperature, less H₂O molecules will join the ice, while the same amount will melt as in the pure water case. This effectively depresses the freezing point. You now will need a lower temperature than 0 °C to form ice in order to make up for this. You can approximately calculate this temperature quite easily because the drop in freezing point is proportional to the amount of sugar (or salt ...) molecules in the solution.

Interestingly, the mass of the sugar doesn't matter, only the number of molecules does: If you dissolve a certain amount of sucrose (a double sugar) molecules, it will affect the freezing point the same way as adding the same amount of glucose molecules, even though glucose is half the mass. The same goes for salt: One NaCl, because it splits up when dissolved in water, will depress the freezing point approximately like two sugar molecules.

The second important point: The concentration of sugar in the water increases as ice forms. The sugar stays in the liquid solution; the ice is pure water. So more ice means a higher sugar concentration in the liquid that remains, depressing the freezing point of the remaining liquid. This means that for any specific temperature, sugar-water will freeze only partially to a certain percentage. You can calculate (for example), if you have 500 g of sucrose dissolved in 1 l of water, and you freeze that to -18 °C, about 79% of the water will be in ice form.

I bought some very cheap enameled steel (not cast iron, stamped steel) pots, for cooking pasta and potatoes and such.

Background: After I dropped my decades old stainless steel pasta pot and the plastic handle broke off, I got some cheap IKEA so-called "stainless steel", which is chrome-free, and it rusted (do not recommend). So I'm trying enameled steel since it's cheap and cannot rust (well except the rims which just have some chromed steel crimped on I guess). Only 40 € for four pots in different sizes.

I can boil water on the electric stove at full blast, and that hasn't broken them, but I also have a super powerful mini induction hob, and that's like 10x faster and I'm afraid to try that in case it might shatter or warp.

Theoretically they're great for cooking liquids because they're not reactive, thin, light and good on induction but I'm kind of afraid of breaking them. Enameled steel used to be a thing here in Germany but pretty rare now. It seems to be almost unheard of in the US, but maybe some people on here from around the world have some experience about what sort of abuse these pots should be able to take.

You all know and love debunking. But have you heard of pre-bunking?

One approach is so-called “pre-bunking” - the targeted presentation of other perspectives and fact-based information. This involves being proactive instead of just reacting. In other words, not just trying to refute disinformation after the fact.

Check out the big brain on Mr. Osintguy. I spent way too much time looking at their sponsors. You can find the funniest shit in their mission statements:

PulseOfEurope: Defend the heart of Europe – with your vote. vote

iac Berlin: Understanding and developing relational approaches in the field of philanthropy yud-rational

Relational approaches are increasingly recognized for their potential to support sustainable solutions and to nurture greater resilience while navigating complex challenges.

The good Lobby: We democratise lobbying not-good

Toguna Leadership:

What do we see as the art of leading people? To be an invested sparring partner as those we lead wrestle with the most fundamental questions, we all bring to work and life: Does my contribution matter? Do I belong (here)? Will I stay relevant and have a future (here)? agony-limitless

Front Europjeski: Literally just "European Front", I guess Eastern Front was too on the nose? freedom-and-democracy

 

Very clever puzzle game. Combines Sokoban-like block pushing with predicate logic. So for example, if you create a rule like "Walls is you", you now control the walls, or you can undo an existing "Walls is stop"-rule and the walls are now non-colliding. The rules themselves are created/destroyed by pushing three blocks together: object IS property.
