AECforWebAssembly VS linux

Great! I have not yet made source maps for my programming language that compiles to WebAssembly, and I probably never will.

Up until today, my AEC-to-WebAssembly was, if somebody tried to use two structures of different types as the second and the third operand to the ?: (ternary conditional) operator, as in this example: ``` Structure First Consists Of Nothing; EndStructure

Well, I have written the first compiler for my programming language, targetting x86, in IE6-compatible JavaScript, and the second compiler, targetting WebAssembly, has been written in C++11. I think that, to choose a language to write a compiler in, you need to look at at least two things:

You can see the releases v2.5.3 and v2.5.2 of AECforWebAssembly on GitHub. They are produced with the same version of GCC, the only difference (as far as I know) is that v2.5.2 was produced directly on Debian, whereas v2.5.3 was cross-compiled from Windows to Linux using Docker.

That could be true. I host my AEC-to-WebAssembly compiler on GitHub, GitLab and SourceForge, and it's only on GitHub that it has 21 stars and 2 forks. On GitLab and SourceForge, it has zero of both.

Well, the main compiler for my programming language is targetting the JavaScript Virtual Machine by outputting WebAssembly. I think it's even better than targetting Java Virtual Machine, because, for one thing, your executables can run in any modern browser if you output WebAssembly. If you target Java Virtual Machine, the users need to actually download your app. Furthermore, there is an official assembler for WebAssembly called WebAssembly Binary Toolkit (WABT), so your compiler can output assembly and not have to deal with binary files. There is nothing equivalent to that for Java Virtual Machine.

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.

> The original less-than check was deemed incorrect

It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.

Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."

I don't think that you believe that, but many developers do.

Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.

Also be aware that sublicensing is not the same as relicensing.

He notoriously hates GNU Emacs, yes.

So If we would only count code and not comments, it is only 9489 LoC Rust. Which would be about 0.03% and if we take all lines and not only LoC it would be around 0.05%

AIUI fsync is built on futex_waitv which has been upstreamed. So this has to be more than that.
