Yes! This is along the lines of what I thought of when I saw ghostty. https://news.ycombinator.com/item?id=42524537 It's too bad I don't use vscode. I think it would be cool to have something that can jump be

If you spent enough time and energy on it.. I'm fairly confident you could get the newest Ubuntu running. You'd have to build your own kernel, manually generate the initramfs, figure out how to and then flash it. You'd probab

You could install Ubuntu 24.04 using debootstrap. That would just get you the user space, though, you'd still have to build your own kernel image.

Are you aware that mainline linux runs on these Jetson devices? It's a bit of annoying work, but you can be running ArchLinuxARM. https://github.com/archlinuxarm/PKGBUILDs/pull/1580 Edit: It's been

Is that why I got down voted? This thing is header-only, I'm guessing it doesn't need rtti or have a big footprint.

Fantastic links. They should be at the top of this thread. This stuff looks really impressive to me. I'm not an expert. I take it that it is implicitly assumed that code running on the server (which I cannot spot the source for) doesn&

How did they do it? The idea for homomorphic encryption has been around a long time, but as far as I am aware the time+space requirements have found to be tremendous, thus rendering any serious implementation of it impractible. If they mana

I went to ghostty.org and spent a long time staring at that animated ghost, and thought of clippy. Except this guy seems to have wider range of emotions. Anyways, I eventually learned this was about a terminal emulator (which is awesome), b

What I like about foot is the heuristics governing text selection with the mouse. I find that more often than not, if I double click with the mouse on some text, what it ends up selecting is just the part I need.

Yeah, totally. I find LLMs are very useful for doing stuff with the preprocessor, too. ChatGPT taught me how to use boost preprocessor (BOOST_PP_FOR_EACH_PRODUCT). Still though, I want to see MyMapType::value_type in compiler errors rather

For the love of God when will c++ compilers finally be able to output template errors that aren't completely expanded and are written in terms of the user's typedefs? Most of the time I spend parsing template errors with boost is

Many people dismiss mathematics because they aren't interested in it. I definitely wasn't interested in doing dozens and dozens of error-prone problem sets that mainly boiled down to performing arithmetic. I don't need to do

In my high school we were basically only instructed to get good at applied math. Calculus. Which more often than not was simply "plugging it in". Most of that work is trivially automatible through Mathematica. When I reached a uni

My model for LDD in my head was, "run the app up until the entry point of the executable, print the loaded DSOs, and exit() before ever starting the exe." That'd get you potentially more libraries than if you just statically

I guess I wasn't sure that DT_NEEDED entries covered everything. Sometimes you have stuff that happens in DT_INIT constructors.

Disentangling who loads what without actually running the app, i.e. allowing a sequence of dlopen() calls to succeed, seems impossible to accomplish in the presence of binary code which cannot be effectively scrutinized.

Yes, there are some wrinkles in upgrading packages on Arch, like you said. I've had to manually install archlinux-keyring with pacman. Ive had to manually upgrade yay because a shared library it is dynamically linked to was upgraded. I

I always have such a difficult time messing with packages on debian. On arch, there is a single PKGBUILD file, and it's basically the simplest thing anyone could think of which makes it bliss to work with. On the other hand, debian&#x2

Are delay slots unique to mips? They're a pretty significant aspect (complication) that I don't see anywhere else. Also, the gp register- don't know of any other arch where you need to set something like that up to access glo

Yeah and key here is that there's nothing to stop you from cloning the repo for a package, checking out an older revision, and running makepkg (granted, it's not guaranteed to work but...)

The GLIBC_TUNABLES can be used to "choose" between different versions of e.g. memcpy at runtime. This can be really useful for debugging, if you want to allow/disallow AVX extensions, for example (even if your CPU supports th

IFunc relocations are how glibc dynamically chooses the best memcpy routine to use at runtime based on the CPU. see https://github.com/bminor/glibc/blob/glibc-2.31/sysdeps/x86_...
