RetrOS-32: a 32bit hobby operating system with graphics, multitasking, and more
RetrOS-32 is a 32bit operating system written from scratch, with graphics, multitasking and networking capabilities. The kernel is written in C and assembly, while the userspace applications are written in C++, using Make for compilation, all licensed under the MIT license. It runs on Qemu, of course, but a variety of real hardware is also supported, which is pretty cool and r … ⌘ Read more

I don’t need an X11 compositor for fancy graphics effects or whatever. I have true hardware support for that.

My TFT just slightly burns in and then it looks like dmenu has a semi-transparent background.

Yeah.

@david@collantes.us Ah, yes, the hardware might not. As I just said in the other thread: No problem, you can keep the same installation. I did so many times on my PC/laptop at work.

@movq@www.uninformativ.de it might, but maybe the hardware will not? Unless, of course, it is a VM.

Chimera Linux drops RISC-V support because capable RISC-V hardware doesn’t exist
We’ve talked about Chimera Linux a few times now on OSNews, so I won’t be repeating what makes it unique once more. The project announced today that it will be shuttering its RISC-V architecture support, and considering RISC-V has been supported by Chimera Linux pretty much since the beginning, this is a big step.

Microsoft is not ending Windows 11 support for Intel’s 8th, 9th, and 10th Gen processors
About two weeks ago, there was a bit of confusion about the system requirements for Windows 11 24H2, because Intel’s 8th Gen, 9th Gen, and 10th Gen processors had disappeared from the list of supported hardware. This seemed rather drastic, even by Windows 11 standards. I skipped posting about it on OSNews because I kind of assumed it must’ve been an error ins … ⌘ Read more

i’ve been a ham since i was a kid, but i haven’t been too active lately. i’ve seen some interesting signed packet radio schemes, but nothing I’ve taken a close look at. i’ve been doing a bunch of research into mesh networking protocols over the years and now that i’m approaching something worth writing i may have to get back into the hardware side of things

@doesnm@doesnm.p.psf.lt May I ask which hardware you have? SSD or HDD? How much RAM?

I might be spoiled and very privileged here. Even though my PC is almost 12 years old now, it does have an SSD and tons of RAM (i.e., lots of I/O cache), so starting mutt and opening the mailbox takes about 1-2 seconds here. I hardly even notice it. But I understand that not everybody has fast machines like that. 🫤

afaik nobody has done this, but i really need some numbers that can indicate the relative performance of various git servers (cgit, gitea, gitlab) on comparable hardware. cgit claims to be hyperfast, but what does that mean in practice?

There are apparently dedicated “fireproof” external hard drives available that do this, and this coincidentally-timed piece suggests I might be able to get closer to what I was thinking in the not-too-distant future: https://www.pcgamer.com/hardware/ssds/researchers-have-developed-a-type-of-flash-memory-storage-that-can-withstand-temperatures-higher-than-the-surface-of-venus/

Feedback on why I didn’t choose Mattermost (lack of OIDC) · mattermost/mattermost · Discussion – My discussions/feedback on Mattermost’s decision to have certain useful and IMO should be standard features as paid-for features on a per-seat licensed basis. My primary argument is that if you offer a self-host(able) product and require additional features the free version does not have, you should not have to pay for a per-seat license for something you are footing the bill for in terms of Hardware/Compute and Maintenance/Support (havintg to operate it).

What if I run my Gitea Actions Runners on some Vultr VM(s) for now? At least until I get some more hardware just for a “build farm” 🤔

@prologic@twtxt.net You more or less need a data center to run one of these adequately (well, train…you can run a trained one with a little less hardware). I think that’s the idea–no one can run them locally, they have to rent them (and we know how much SaaS companies and VCs love the rental model of computing).

There’s a lot of promising research-grade work being done right now to produce models that can be run on a human-scale (not data-center-scale) computing setup. I suspect those will become more commonly deployed in the next few years.

@mckinley@twtxt.net Yeah, that’s more clear. 👌

Systems that are on all the time don’t benefit as much from at-rest encryption, anyway.

Right, especially not if it’s “cloud storage”. 😅 (We’re only doing it on our backup servers, which are “real” hardware.)

@prologic@twtxt.net I think those headsets were not particularly usable for things like web browsing because the resolution was too low, something like 1080p if I recall correctly. A very small screen at that resolution close to your eye is going to look grainy. You’d need 4k at least, I think, before you could realistically have text and stuff like that be zoomable and readable for low vision people. The hardware isn’t quite there yet, and the headsets that can do that kind of resolution are extremely expensive.

But yeah, even so I can imagine the metaverse wouldn’t be very helpful for low vision people as things stand today, even with higher resolution. I’ve played VR games and that was fine, but I’ve never tried to do work of any kind.

I guess where I’m coming from is that even though I’m low vision, I can work effectively on a modern OS because of the accessibility features. I also do a lot of crap like take pictures of things with my smartphone then zoom into the picture to see detail (like words on street signs) that my eyes can’t see normally. That feels very much like rudimentary augmented reality that an appropriately-designed headset could mostly automate. VR/AR/metaverse isn’t there yet, but it seems at least possible for the hardware and software to develop accessibility features that would make it workable for low vision people.

@prologic@twtxt.net yeah. I’d add “Big Data” to that hype list, and I’m sure there are a bunch more that I’m forgetting.

On the topic of a GPU cluster, the optimal design is going to depend a lot on what workloads you intend to run on it. The weakest link in these things is the data transfer rate, but that won’t matter too much for compute-heavy workloads. If your workloads are going to involve a lot of data, though, you’d be better off with a smaller number of high-VRAM cards than with a larger number of interconnected cards. I guess that’s hardware engineering 101 stuff, but still…
