12 years since it was released, zero remotely executable code vulnerabilities. By some measures, the most secure operating system of the 21st century.

Your move, FreeBSD.

I quite liked how the original Linux fix for the Spectre-style speculative execution bug on Intel processors was called “Forcefully Unmap Complete Kernel With Interrupt Trampolines”, but alas, in the interest of diplomacy it was renamed to “Kernel Page Table Isolation” (KPTI) rather than “FUCKWIT”.

Doesn’t feel like it was that long ago, but of course, all search results are dogshit in this new age: https://wccftech.com/intel-kernel-memory-leak-bug-speculative-execution-performance-hit/

Yeah, mine was similar. Had some old Win95 machines from work that were getting thrown away; scavenged as much RAM as possible into one case and left Red Hat Linux downloading overnight on the company modem. Needed two boxes of floppy disks for the installer, and I joined up a 60 MB and an 80MB hard drive using LVM to create the installation drive. It was a surprisingly functional machine - much better at networking than it was as a Win95 computer - but yeah, those days are long gone.

I really like the book - I think it’s one of his best. Subtle ‘unreliable narrator’ mind-fuck from beginning to end, nicely written and characterised. The film of it is an abomination, though.

CMake, which is kind of the universal standard build system for C++ now, has “fetch content” since v3.11. Put the URL of a repository (which can be remote, but also local, which is handy) and optionally the branch / commit ID that you’d like, and it will pull it into your build directory automatically. So yeah, you can pull anything nefarious that you’d like. I don’t think most people would question pulling and building a library from Github as part of the build, especially if it had a sensible name for the task at hand.

Yeah, swapped out grub for systemd-init on a running Arch system not too long ago. Arch is cool with it. Be sure not to make any really bad typos while you’ve not got a boot manager, of course.

They’re occasionally the crisp of choice in pubs; an excellent accompaniment to an 80/-. Suppose there’s worse criteria for your pub crawls. But aye, a weird omission - you’d be thinking there’s plenty of wagons on the Stranraer ferry that could bring a few palletloads over.

After having used Grub for about twenty years (eek) I was uncertain about the alternatives, but systemd-boot is absurdly better. Much better configuration, much better documentation, fixes a while pile of bugs that Grub team had as “won’t fix” for years and years. No reason to ever go back.

TempleOS network edition.

Nicole the Polish girl from Toronto is my fediverse girlfriend, damnit. Get your own.

True. I’d mentally envisioned it as a whole series of “bread powered water wheels” down the side of the building, with a furnace at the bottom. Nothing actually going fast enough for friction to matter. A machine that only tried to convert all the kinetic energy at the bottom would be wasteful, as you say.

Plainly, we’re going to have to put some engineering design time into the concept of this.

A kilogram of bread is about 2000 calories, about 9 kJ. Your body “burns” food too - probably more efficiently than you could make a steam engine for the same, but it’s about that much.

Energy from gravity is equal to mass * gravity acceleration * height. 1 kg of bread in a 9.81 m/s/s field has the same gravitational potential at “about a kilometer”.

If you’re throwing magic stake baguettes off the top of the Burj Khalifa, the energy would be about equal.

Well yeah. You barely use groups on a personal machine - maybe once and done for audio and VMs, depending on what distro you use - and at work you’d automate that shit, probably have it centralised.

Kind of. It’s the Linux kernel that manages all of the controller drivers and makes them available to userspace, mostly via the evdev interface. SDL is a library for managing graphics, sounds and events in a generic way on multiple platforms and devices. It’s overwhelmingly the most common library used for Linux games - Steam used it for all of their Linux-native ports of Source engine games, for instance. But it also presents all gamepad events in a consistent way regardless of their “true source”, so generic devices tend to work with every game.

SDL3 mostly clears out all the clutter from the previous versions of SDL. It’s a mature library and gamedev has come a long way in that time. Getting rid of all the weird stuff that the API accumulated makes it easier to use and maintain. Plus there were things like managing audio generally, and pen-and-touch gestures mobile phones and tablets, that were quite the head-scratchers before. That’s all a bit easier now.

Filesystem-as-a-db is why MongoDB is webscale. You just turn it on and it scales right up.

Absolutely NO sexuality explicit content. This includes, but not limited to, images/videos/chat around sexual acts. There are other places on the internet for this.

Yeah, I was pondering this earlier. In exchange for giving up quite a lot of the CPU die, you can have some NPU functionality instead; rather than having to offload everything to the cloud, you can preprocess some of it first, and then offload it.

Speech-to-text and text-to-speech plus general battery efficiency are reasonable use cases for a phone, certainly more so than a laptop and much more so than a desktop. But as you note, those models are going to be small, and RAM and backing storage on phones tends to be slow and limited.

Was also considering that an NPU gives no benefit at all unless code has been written for it; it’s a bastard to write code for something so concurrent, and giving up CPU die for an NPU instead of more cores and cache means that your phone will generally be slower unless it’s largely used for NPU tasks. Plus if you need to offload to the cloud for most useful tasks anyway, it’s just a marketing gimmick that makes your phone less good for most uses.

Assuming you had a pretty decent monitor and graphics output in the 90s, it may have been 800x600, but more likely 640x480, and you’d have been using the standard issue bitmap font with no anti-aliasing, blitted to screen using software rendering. Probably in a single colour, too.

Alas, the problem with that is that it doesn’t scale. On xterm a 4K monitor, I can watch Vim redrawing the screen, paging through logs is painful. Use Kitty for the same, it’s instant, I can flip through tabs and split screens too, and have niceties like anti-aliased fonts and transparency if I want them.

Some people spend a lot of time in the terminal, so I can’t fault them for taking the time to make a nice working environment and sharing that work with others.

I’d probably go with a “kitchen” metaphor here.

The executable for a program is a list of instructions for the CPU to execute. Windows and Linux gaming machines will usually use x64. Most of the instructions are logic eg. how to add numbers together, what comparisons to make, what to copy from one place to another; and they’re exactly the same on both Windows and Linux, you can run them as-is.

Some instructions ask the operating system to do things, like open a file to read. Windows and Linux do these quite differently, but you know how one works then you can change it to the equivalent ask for the other machine. Making the translation takes a moment, but some things are faster on Linux than Windows, so it’s not very easy to generalise as to whether it’ll be faster overall to do certain things. The really important operating system calls for games tend to be messages to pass to the GPU, and the Proton team have put a lot of work into making these as fast as possible.

If you think of it like following a food recipe, then given the ingredients you’d expect that most people would produce exactly the same meal by following it. Most of the steps will be exactly the same for everyone. However, if a step requires a piece of equipment that you don’t have, then it might take longer to follow the recipe if you’ve got to make do with different stuff. Similarly, you might be able to prepare things quicker if you’ve got a whole pile of restaurant-level gear and can do some of the steps differently.

Flightless Mango used to have some good comparisons, but they’re about four years out-of-date, now. Even then, you’d expect between 10% worse and 5% better on Linux. https://flightlessmango.com/benchmarks/

Forbes article here is from this year; expect between 5% worse and 25% better when running on Linux. https://www.forbes.com/sites/jasonevangelho/2024/08/21/linux-scores-a-surprising-gaming-victory-against-windows-11/

General experience is that generally there’s no noticeable difference at all; some games that use new features might have bad performance until the new features are implemented. Last game I really had a problem with was Horizon Zero Dawn. Elden Ring had bad performance on launch day, but was fixed the next day I think.
