linux VS CPython

>A pidfd does not let you hold a reference to an individual thread, only to a process

I think that's outdated: https://github.com/torvalds/linux/commit/64bef697d33b75fc06c...

For specific cases I can find ext4 explicitly checking for RO https://github.com/torvalds/linux/blob/8c06da67d0bd3139a97f3...

FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

These are a bit easier to see what's going on:

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

Imagine planning your dream vacation, but instead of spending hours searching online, an intelligent assistant arranges everything for you. Sounds like a fantasy, right? What if I said you could build this AI travel agent with just a few lines of Python code? Yes, it's that simple. In this guide, we'll walk you through the process step-by-step, so you can have your travel assistant ready to help with your next adventure.

Python

Python bytecode is like a secret language that Python uses behind the scenes. When you write your Python code, it doesn’t run directly. Instead, Python translates your code into bytecode, a set of instructions that the Python interpreter can understand and execute.

Ensure you have Python installed on your system. You can download it from the official Python website. Verify the installation by running:

We strongly encourage maintainers of third-party Python projects to test with 3.13 during the beta phase and report issues found to the Python bug tracker as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Tuesday 2024-07-30). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.13.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.13 as possible during the beta phase.
