Funnily enough, one of the few legitimately impactful non-enterprise uses of AVX512 I’m aware of is that it does a really good job of accelerating emulation of the Cell SPUs in RPCS3. But you’re absolutely right, those things are very funky and implementing their functions is by far the most difficult part of PS3 emulation.

Luckily, I think most games either didn’t do much with them or left programming for them to middleware, so it would mostly be first- and second-party games that would need super-extensive customisation and testing. Sony could probably figure it out, if they were convinced there was sufficient demand and potential profit on the other side.

The Xbox 360 was based on the same weird, in-order PowerPC 970 derived CPU as the PS3, it just had three of them stuck together instead of one of them tied to seven weird Cell units. The TL;DR of how Xbox backwards compatibility has been achieved is that Microsoft’s whole approach with the Xbox has always been to create a PC-like environment which makes porting games to or from the Xbox simpler.

The real star of the show here is the Windows NT kernel and DirectX. Microsoft’s core APIs have been designed to be portable and platform-agnostic since the beginning of the NT days (of course, that isn’t necessarily true of the rest of the Windows operating system we use on our PCs). Developers could still program their games mostly as though they were targeting a Windows PC using DirectX since all the same high-level APIs worked in basically the same way, just with less memory and some platform-specific optimisations to keep in mind (stuff like the 10MB of eDRAM, or that you could always assume three 3.2GHz in-order CPU cores with 2-way SMT).

Xbox 360 games on the Xbox One seem to be run through something akin to Dolphin’s “Übershaders” - in this case, per-game optimised modifications of an entire Xenon GPU stack implemented in software running alongside the entire Xbox 360 operating environment in a hypervisor. This is aided by the integration of hardware-level support for certain texture and audio formats common in Xbox 360 games into the Xbox One’s CPU design, similarly to how Apple’s M-series SoCs integrate support for x86-style memory ordering to greatly accelerate Rosetta 2.

Microsoft’s APIs for developers to target tend to be fairly platform-agnostic - see Windows CE, which could run on anything from ARM handhelds to the Hitachi SH-4 powered Sega Dreamcast. This enables developers who are mostly experienced in coding for x86 PCs running Windows to relatively easily start writing programs (or games) for other platforms using those APIs. This also has the beneficial side-effect of allowing Microsoft to, with their collective first-hand knowledge of those APIs, create compatibility layers on an x86 system that can run code targeted at a different platform.

Yeah, Windows’ bullshit is what drove me to Linux in the first place. I only have it on my gaming system, and only because Discord’s stupid screensharing doesn’t transmit audio on Linux, NVIDIA’s drivers for Linux suck balls (going AMD next time now that their cards are good again) and there are a couple of games my friends play that have issues on Linux. I’ve never run into a game on my everyday laptop that Linux couldn’t run, and the Steam Deck will take basically whatever you throw at it.

Windows is a barely-functional rat’s nest of code spaghetti that falls apart at complete random. Sometimes your audio drivers will just stop working for no apparent reason. Sometimes your computer will just refuse to connect to the internet until you do a clean install. Windows Update apparently runs Prime95 in its spare time and so does the Antimalware Service Executable. I hate using it so much. I wish Windows would just curl up and die.

This is the first I’ve heard of the JPEG XL format, but it sounds pretty good!

Hopefully it doesn’t get misused by websites to mangle lossless compressed images with so much compression they’re barely visible to save a few kilobytes, though.

Been using LineageOS with microG on my phone for the last couple of years out of a general distrust for Google, using open-source apps in place of the Google ones. My phone stopped getting OEM updates after Android 12, so being able to use Android 13 through LineageOS is a plus. Main downsides are that some apps don’t play nice with microG and that unlocking the bootloader makes banking apps stop working.

In the case of the Surface Go family, there isn’t really anything comparable from other companies. It’s unironically the best compact tablet I’m aware of that you can put Linux on, and it runs Pop!_OS without issue once you disable Secure Boot. The only better Linux tablet for me would be an iPad Mini, but you can’t put Linux on one of those and even if you could it’s ARM-based so most proprietary apps won’t work on it.

In general, your tablet options for something smaller and handier than full-size 2-in-1s are pretty limited if you don’t want to be running iPadOS, so excluding Microsoft’s devices from the running if you want to put Linux on your tablet is pointless. Yeah, buying a Surface Laptop to put Linux on there is a bit weird, but I can see the Surface Pro family yielding a good ARM Linux tablet some day.

USB-C hubs all seem to be dodgy crap made by anonymous Chinese companies and resold through various companies, including the likes of Apple. There’s an absolute dearth of hubs made by actual reputable firms.

Centralisation in this instance refers to control over the network and standard itself rather than control over what’s posted on it. There’s no single authority that can unilaterally change how every Fediverse instance and system works - for example, there isn’t anyone who can decree that from now on Lemmy will no longer allow connections from Canada, or that nobody is allowed to post pictures of capybaras any more.

It’s intended to prevent a /u/spez or Elon Musk situation where one asshole can bring down the entire ecosystem built around an API. Nothing stops anyone else from hosting their own instance if they dislike lemmy.world, whereas if you don’t like Twitter, you can’t just host your own copy of it.

The very fact that they work like mobile apps is a reason to dislike them, honestly. At least Flatpaks aren’t total fucking crap like Snaps.

OsmAnd actually works pretty well in my experience, at least in the UK. It’s not always up to date or fully-detailed but it’s far from useless and I appreciate that. It’s my primary map program on my phone.

I can only imagine how thin the margins will be on laptops that are physically incapable of running their own operating system and basically don’t qualify as general-purpose computers. The computer itself will be streamed to you over the internet and you’ll just have an IPL that handles your keyboard and mouse, the display, the network connection and the encrypted memory buffer you use to send files to your cloud PC or receive them onto a Microsoft-authorised USB device for external transfer.

Will also be so much fun in 5-10 years when only enterprise customers are allowed the luxury of being sold a local version of Windows, so your whole laptop freezes up every time your connection is interrupted and trying to turn it on without an internet connection just takes you to a 404 page baked into the bootstrap ROM.

Because the last decade has shown the rather terrible consequences of private, proprietary and profit-driven networks like Twitter and Meta’s various crap becoming de facto part of the common infrastructure of public life. A lot of public transit services publish service updates on Twitter. Most politicians have a Twitter presence. Many restaurants and small businesses don’t even have websites anymore - just Facebook pages.

We want to stop exploitative for-profit entities from furthering their stranglehold on essential parts of everyday life. Nobody should be forced against their will to use crap like Facebook or Twitter, and that means advancing viable alternatives to those platforms that can fill the role they do in the internet era. If the “digital town square” idea is to live on, it should be as a commons like an actual town square, not a publicly-traded company or a billionaire’s personal cult compound.

For real, the world of Linux gaming owes a lot to Valve and to Proton’s contributors. The last five years have taken gaming on Linux from a fiddly nightmare to, in many cases, performance as good as native. There has never been a better time to run Linux as your primary operating system.
