hi /tech/ , have you seen the federated chans that are coming along?

https://fchan.xyz is 4chan + ActivityPub. It's a bit rough around the edges, but it's going to be able to connect to other ActivityPub projects like Lemmy and Mastodon later.

https://0chan.vip is a tag-based textboard that will soon gain a scraper. It also has user-managed boards with stickies, permasage, and a "soft delete" that hides threads in board view, but doesn't delete them from the server. see http://0chan.vip/b/meta/

NNTPchan was kind of cool but it was pretty busted. It fizzled out after a year.

I spent a fair bit of time trying to understand NNTPchan when 8ch was shut down because I see decentralized federation as the only real way to fight back against the CDN-DDoS racket and resist censorship. It was disappointing to me when so many diaspora communities went and decided to just clone the old traditional image board site model all over again without seeking to address how they lost their community in the first place. It was even more disappointing to find out how unpopular NNTPchan was.

if you want that than make a general decentralization layer protocol, that everybody can use to build on top, add something to the general purpose network stack, instead of making specialized applications.

The two sites ought to develop and adopt an fchan fork and then follow each other. But of course they never would because the ability for users to move to another server without creating an isolated community would directly threaten janny privilege.

Debian really is the worst distro for KDE. KDE has a rapid pace of 3 releases per year. You're going to be stuck with 5.20 and KDE window manager had major rework in 5.21 and is being massively pumped by valve right now. And many new improvements are coming soon with 5.23

Well, same goes for a lot of other packages in general, on Ubuntu LTS as well. If you really need some patch or a feature then you have to edit and compile that package yourself, which is not always possible due to dependencies. But sometimes it's just a case of maintainers compiling packages without some shockingly basic flag - like libcurl without brotli support (now commonly used by servers to compress web pages, so you need it to decompress). The good side is that packages are rarely updated so you don't have to do this regularly, but it's still a pain in the ass.

Debian Testing is actually pretty stable itself though, but the drawback is that security patches are not backported like they are to Stable, so you have to wait until they're transferred from Sid the regular way. If something else blocks that package from arriving at Testing then your system is left vulnerable. So now you have to follow their security announcements and patch things yourself if it's something serious. Also pain in the ass.

A short while ago Valve announced and demoed a functional gaming handheld, that uses a AMD labtop CPU with a very powerfull iGPU and a beefed up memory-bus for about 500 money.

The big wow was that it was running Arch Linux as operating system under the hood, with access to a desktop mode, that would actually be usable as a PC. Most of the people (including me) in the Free Software and Linux scene were excited about this because it means more people using Linux and maybe better driver support.

I have only ever used steam once and i managed to buy a game and then somehow invalidate my license key or user account that was attached to it. I'm pretty sure this was user-error, but still i felt like i was being punished for legally buying a game. I kinda gave up on gaming, although i do sometimes still follow technical news about video game engines.

My experience with DRM systems in general is that it's a fickle bitch and proprietary software doesn't just mean that it's violating the 4 User Freedoms bequeathed to us by Saint Stalllman, it also means that it's probably going to stop working at some point. At least in my case I managed to wrench quite a number of DRMed programs i payed for. I basically think that Intellectual property enforcement is some kind of political, ideological or religious terror, that can only be explained by an unreasonable amount of evilness. I know this sounds a little silly but consider that it feels like unpredictable unexplainable punishment when drm wigs out. Stallman really can feel like a angel descending from the sky telling you a transcendental truth. (Figuratively speaking)

And here is where my doubts come about, steam uses DRM for most of it's games, and Linux users in general really don't like DRM, or proprietary software, and there might be a lot of friction, about it. However I don't think Valve will switch to windows, because Microsoft has it's own videogame-store on windows as well as their own console that is the arch nemesis of Valve and steam. Their dependence on Microsoft is an existential risk and they need something like the steamdeck that is independent of MS to survive as a company. But i fear that there will only be a honeymoon period after which Linux ends up as a battered wife.

I was re-considering my game-abstinence and getting a steamboy, because it looks like you could use it while lying on a sofa and there are a number of puzzel games like the ones from ZachtrPost too long. Click here to view the full text.

Bad idea to sacrifice your abstinence for this. For a few games here and there a laptop on a sofa should do - since you say you'll install Arch anyway and go to GOG instead. Among popular puzzlers most work natively on Linux, and many of them are also on GOG. How large is the screen on this thing anyway? Most Zachtronics would be unplayable on a very small screen, and at least 3 of them have you write code which would also be a pain in the ass on this thing.

If you would buy a laptop or handheld for playing games on a sofa, consider getting an armchair (with a footrest) for your pc instead. It's really comfy :-)

He probably had lucid moments and saw no way to escape his illness. It's also sad how dumbasses trolled him online and contributed to his illness worsening, he had a cult following but some people just saw him as a lolcow. Dude had so much potential. Making TempleOS by himself is already an incredible feat, but without the schizophrenia he could've been much bigger.

Yes, in fact, they will, that's one reason why it's such an attractive engineering project. You can also make them dramatically simpler outside an atmosphere when you don't have to worry about the kind of weathering you experience on Earth.

>>10637
That's unnecessary because lunar photovoltaics are so much better than Earth photovoltaics because they don't have an atmosphere to contend with.

>>10638
You seem unaware of this but the moon actually has next to no atmosphere. We can still see craters on it that are billions of years old because it takes a really long time to overturn the lunar surface with "moon dust". People far smarter than you have been thinking about this idea for far longer. It's been feasible since the '80s.

good point. there's no pesky oxygen

>That's unnecessary because lunar photovoltaics are so much better than Earth photovoltaics because they don't have an atmosphere to contend with.

there's only 30% more sunlight hitting the moon. not super impressive. this and the lack of atmosphere makes the thermal situation difficult. more on this later

>You seem unaware of this but the moon actually has next to no atmosphere

yes, and this is the problem. the moon is surrounded by what's called a dusty plasma. dust gets thrown around by electrostatic effects and there's no atmosphere to stop this. this is worst at the terminator, where the surface charge changes from positive to negative at sunset (and opposite at sunrise), which throws enough dust around that austronauts were able to see light reflecting off it. look up the "streamers" seen during Apollo. t someone who has actually worked with this stuff

what's even worse is the thermal situation. semiconductors degrade exponentially faster the hotter they get. space thermal system rely on coatings with wavelength dependent emissivity. you can't use this on a PV, obviously, at least not on the front, or you'd reflect away the very energy you're trying to absorb. your surroundings are 130°C, and your PV cells will likely be too. it might be possible to cover the entire surface underneath the cells with multi layer insulation (MLI) blankets. if you get the angles right then the temperature drops to around 65°C ((130+273)/2^0.25-273). assuming you can make them in-situ of course. there's aluminium up there at least

>People far smarter than you have been thinking about this idea for far longer. It's been feasible since the '80s.

I've read many of these papers. it's a waste of labour compared to making do with Earth

the moon is in a vacuum, you might be able to use an electrostatic charge to deal with dust.
>>10639
of course PV is nicer than a solar thermal concentrator because it's just one solid piece that makes electricity, but STC does have better tolerance for the harsh conditions of space. What's the radiation pressure on the moon, will that harm the longevity of PV ?
>>10640
How much is the temperature difference between sun and shade on the moon? If you are looking at semiconductors, it might also be worth to consider peltiers if the delta T is high enough.

>you might be able to use an electrostatic charge to deal with dust
possibly yes. but everything being electrically connected might work against you. you want high voltage to keep current low and efficiency high. but this means you also set up an E-field that will throw dust around. what might work is a thin net over everything that is appropriately charged. you have to be careful though - too positive and you attract the negatively charged dust, too negative and you attract the positively charged dust on the ground

>How much is the temperature difference between sun and shade on the moon?

temperatures fluctuate between -170°C and +130°C (100-400 K) over each month, at the equator. the ground is about as insulating as styrofoam, so it gets cold pretty fast if you say unfurl a sun shade. things get worse if you're in a valley or crater
STC is probably a better bet. on the other hand they use moving parts

>it might also be worth to consider peltiers if the delta T is high enough

and waste all the electricity you just generated?
