In the manpage for vfork, Linux in particular

> As with fork(2), the child process created by vfork() inherits copies of various of the caller's process attributes (e.g., file descriptors, signal dispositions, and current working directory); the vfork() call differs only in the treatment of the virtual address space, as described above.

so it seems Linux does define the behavior of vfork, but if you rely on it, your code won't be portable to other POSIX systems

> If you're not overcommiting, that fork will fail, because total memory consumption will be 1200 MB which is more than 1GB. That somewhat restricts program design.

Does this accounting apply to vfork as well?

As a non Malawian no, but I do think its important to ask what the local sentiment of their country is.

Now that makes sense, so its legal because the contributors can still access their code

Thats a really big deal, how did they legally managed to do the license change? I was under the impression that only works if the original owner is the doing most work

VK_KHR_buffer_device_address has 91.3% support

and

VK_KHR_variable_pointers has 98.66% support

looks good to me

When I personally use chatgpt and friends, I am not seeing any slowdowns or anything, meaning that their servers can handle the loads just fine. So then, why are these companies spending so much building new capacity if the current capacity is enough?

Microsoft itself is 73% owned by institutional investors, so more of the same really.

You mean the locking would be done in software?

I assume to save on resources, even if your algorithm is not much more taxxing on silicon, maybe the designers at intel and amd just didn't think optimizing split locks was worth it

> chat.agent.maxRequests

"Maximum number of requests that copilot can make using agents"

I don't get how this setting is relevant?

cylemons — Sun, 05 Apr 2026 09:52:53 +0000

There is a limit on how much copilot can do in one request, pretty generous but after some time vscode will say "this request is taking very long, do you want to continue" and that would count as a seperate request

cylemons — Sun, 05 Apr 2026 05:18:17 +0000

I guess Microsoft wants us to think about all these copilots as a single product.

Like, "the copilot in visual studio", "the copilot on github", "the copilot on office" etc.

This a toolchain issue rather than OS issue. This wounldn't have been a problem if gcc/clang just took a --stdlib-version option and built the executables linking to that version of glibc or equivalent.
