How faithful was that storyline to the Tolkein lore? Did he really write a book where a commander driven literally insane by zeal is vindicated, saves the lives of the men in her company like a mary sue, only to be mutinied and sprung by he

You mean _start()'s stack pointer. Libc can secure them and it's fine. It would probably break the ANSI C standard though if you can't modify argv and environ though. So Libc would need to copy them. But that limits the usefu

by jart 4y ago
Well it technically does if you make a new stack with mmap(MAP_STACK) (or simply round down the stack pointer by a page size) and remove the write access to the top of the original stack and mimmutable it.

The msyscall() man page. The Cosmopolitan Libc source code. In the cosmoverse, we produce static executables that run on six operating systems. The only Libc we use is obviously our own. So when our executables get loaded on OpenBSD, we do

Now all we need is for PROT_EXEC to not imply PROT_READ like Android.

> Linux doesn't mandate any libc Neither does OpenBSD. You're misunderstanding how msyscall() works. It's like Highlander. There can be only one.

It's beautiful but there's nothing I can hold in my hands here. See https://news.ycombinator.com/showhn.html It would help if this was open source but it's a 122kb minified JavaScript blob. That's not te

I'm not an electrical engineer or musician, but I feel like there has to be some kind of hack here that would tickle a programmer like me. It felt like the video started getting into that around the 9 minute mark when he said what he w

It's bad enough to make packages quadratic.
1331.
by jart 4y ago
No I don't think so, but I'm not certain. I think with Go the problem always had more to do with the way the language is designed, making it difficult for the linker to prune dependencies.

What are the geopolitical aspects of having a flying toy built in China?

by jart 4y ago
Nah eventually every operating system is just going to support x86_64-linux-gnu and there won't be a need for APE in our glorious future. In that case, Cosmopolitan will just be a non-GPL libc that goes as fast as Glibc. But until all

Yes we're already stuck with all these mono-cultures, so why not just define the union of all these mono-cultures into a single build target?

Are you telling me that you don't see the benefit to clicking a build button on Linux, scp'ing to your website, and saying done -- versus -- setting up Jenkins, buying a Windows license, buying an Apple license, setting up six VMs

Well it helps, but it'd be like spooning water out of a bucket when a faucet is pouring more into it. The NPM dependency model solves the diamond dependency problem by schlepping in multiple versions of the same package. C / C++ &

Rust adopted Node's quadratic dependency model, so Rust binaries are going to be O(n^2) larger and tree shaking isn't going to help unfortunately.

There's so much great stuff going on in the cosmoverse that it's hard to keep track of it all! We recently started https://github.com/shmup/awesome-cosmopolitan for that reason.

There's also https://github.com/jacereda/cosmogfx We've been thinking about rekindling that effort at some point.

It was merged: https://github.com/zsh-users/zsh/commit/326d9c203b3980c0f841... We patched fish too! Plus NetBSD sh and FreeBSD sh.

Because end users use multiple operating systems these days. Also, no. The operating system integration code is tiny in the grand scheme of things. Consider Fabrice Bellard's JavaScript interpreter. If I build it for six operating syst

That's a fat nop, or cs nopw 0x0(%rax,%rax,1) to be precise. .byte 0x66,0x2e,0x0f,0x1f,0x84,0x00,0x00,0x00 # f.▼ä .byte 0x00,0x00 ld.bfd uses them to fill empty spaces. See also `o//tool/decode/x86op

Don't you need negative displacement to be turing complete? And wouldn't negative displacement always entail non-ascii characters?

Did you read the article? The only one I could foresee breaking is if OpenBSD decided to one day implement auxiliary values.

GitHub never deletes anything you push. Even if you rebase and force push, that old information is still accessible. Also why would you drag out such an ugly article to make a point?
