Probably for themselves only.

Oh that makes more sense. I probably took you too literally.

Without the chroot, that's how shared webhosting works but it can be hundreds or thousands of sites, depending on resource usage and server capacity.

I maintained a CEPH cluster a few years back. I can verify that speeds under 10GbE will cause a lot of weird issues. Ideally, you'll even want a dedicated 10GbE purely for CEPH to do its automatic maintenance stuff and not impact storage clients.

The PGs is a separate issue. Each PG is like a disk partition. There's some funky math and guidelines to calculate the ideal number for each pool, based upon disks, OSDs, capacity, replicas, etc. Basically, more PGs means that there are more (but smaller) places for CEPH to store data. This means that balancing over a larger number of nodes and drives is easier. It also means that there's more metadata to track. So, really, it's a bit of a balancing act.

could be used for social welfare systems

For needy billionaires, maybe.

Sith are a fictional sect of religious space wizards from a space opera. While they may have inspiration from religious sects of reality, they are very much not real. So, whether or not they deal in absolutes has absolutely no consequences to reality outside of the Star Wars fandom.

Natively install RPM packages? Really, there's not much. Find a setup that you like.

Trackball/trackpoint built into the Svalboard.

a private equity firm injected 100m

That's all that one needs to know. Once those leeches are involved as investors, it's over. They demand enshitification from our destroy everything that they touch for a quick buck.

Finland was no NATO and not even the USSR touch it.

If you omit the middle of the 20th century, sure. The Finns declared independence from the Russian Empire in 1917, under the approval of the Bolsheviks' Declaration of the Rights of the Peoples of Russia. In 1934, Finland and the USSR reaffirmed a non-aggression pact for 10 years. In 1939, after penning a deal with Hitler to carve up Europe between the Nazis and the USSR, Stalin demanded that Finland, who had maintained a stance of neutrality, cede territory for military use and, when they refused, ordered shelling and invasion.

Neutrality or even open trade did not prevent the USSR from invading then, not did handing over nukes save Ukraine from invasion in 2014.

As for useful implementation, my cousin is an orthopedic surgeon and they use VR headset and 3D x-ray scanner, 3d printers and a whole bunch of sci-fi stuff to prep for operation, but they are not using a meta quest2, we're talking 50k headset and million dollar equipment. None of that does anything to the gaming market.

That's really awesome and I love seeing that the tech is actually seeing good uses.

Yeah. A lot of what you're saying parallels my thoughts. The PC and console gaming market didn't exist until there were more practical, non-specialty uses for computing and, importantly, affordability. To me, it seems that the manufacturers are trying to skip that and just try to get to the lucrative software part, while also skipping the part where you pay people fair wages to develop (the games industry is super exploitative of devs) or, like The Company Formerly-known as Facebook, use VR devices as another tool to harvest personal information for profit (head tracking data can be used to identify people, similar to gait analysis), rather than having interest in actually developing VR long-term.

Much as I'm not a fan of Apple or the departed sociopath that headed it, a similar company to its early years is probably what's needed; people willing to actually take on some risk for the long-haul to develop the hardware and base software to make a practical "personal computer" of VR.

When I can code in one 10 hours a day without fucking up my eyes, vomiting myself, sweating like a pig and getting neck strain it will have the possibility to take over the computer market, until then, it's a gimmick.

Absolutely agreed. Though, I'd note that there is tech available for this use case. I've been using Xreal Airs for several years now as a full monitor replacement (Viture is more FOSS friendly at this time). Bird bath optics are superior for productivity uses, compared to waveguides and lensed optics used in VR. In order to have readable text that doesn't strain the eyes, higher pixels-per-degree are needed, not higher FOV.

The isolation of VR is also a negative in many cases as interacting and being aware of the real world is frequently necessary in productivity uses (both for interacting with people and mitigating eye strain). Apple was ALMOST there with their Vision Pro but tried to be clever, rather than practical. They should not have bothered with the camera and just let the real world in, unfiltered.

 

I'm ridiculously excited. After being held up in customs for a few days, my FW16 DIY Edition (no GPU) has finally arrived. Unfortunately, I've got the rest of the workday to finish before I can get started.

For "vitamins", I grabbed a 1TB SK Hynix P31 Gold m.2 2280 (still deciding what 2230 to get) and 32GB (2x16GB) of G.Skill Ripjaws DDR5 CL40@5600. I haven't had anything so modern in decades and am incredibly excited to see what fun I can get up to with so much RAM.

First order of business, after doing hardware tests to ensure that nothing needs an RMA, and updating any firmware, is to install my NixOS base system and get it setup as a QEMU/KVM hypervisor so that the real fun of trying out the list of recommended and esoteric distros that the Linux community suggested can start. Once I get bored of that, it'll be time to start designing the parts to transform the machine into a hardware hacking/tinkering cyberdeck.

What are you folks doing or planning to do with yours?

 

Hey folks! I think this request is right up this comm's alley. I'm sure that we all know bogo sort but, what other terrible/terribly inefficient algorithms, software architecture, or design choices have you been horrified/amused by?

I, sadly, lost a great page of competing terrible sorting algorithms, but I'll lead with JDSL as a terrible (and terribly inefficient) software architecture and design. The TL;DR is that a fresh CS guy got an internship at a company that based its software offering around a custom, DSL based on JSON that used a svn repo to store all functions in different commits. The poor intern had a bad time due to attempting to add comments to the code, resulting in customer data loss.

Hey folks! I'm getting a fresh laptop for the first time in about a decade (Framework 16) in a couple of months and am looking forward to doing some low-level tinkering both on the OS and hardware. I'm planning to convert into a "cyberdeck" with quick-release hinges for the screen since I usually use an HMD, built-in breadboard, and other hardware hacking fun.

On the OS, I'm planning to try NixOS as a baremetal hypervisor (KVM/QEMU) and run my "primary" OSes in VMs with hardware passthrough. If perf is horrible, I'll probably switch back to baremetal after a bit. But, I'm not likely going to be gaming on it so, I'm not likely to have much issue.

Once the hypervisor is working in a manner that I like, I should have an easy time backing up, rolling back, swapping out my "desktop" OS. I've been using Linux as my pretty much my only OS for over a decade (I use MacOS as a glorified SSH client for work). Most of my time has been on distros in the Debian or RHEL families (*buntu, Linux Mint, Crunchbang, CentOS, etc) and I pretty much live in the terminal these days.

With all of this said, I am coming to you folks for help. I would like you folks to share distros, desktop environments, window managers that you think I should give a try, or would like to inflict on me and what makes them noteworthy.

I can't guarantee that I'll get through suggestions, as my ADHD has been playing up lately, but I'll give it an attempt. Seriously. If you want me to try Hannah Montana Linux, I'll do it and report back on the experience.

EDIT: Thank you all for your fantastic suggestions. I'm going to start compiling them into a list this weekend.
