There are a lot of inline-asm related bugs in the compiler. I'm hitting them almost daily (I'm writing a kernel, so a fair bit of asm is going on here). You can see them in the bug tracker[0]. Stabilizing inline asm in its curre

Well, everything I've said here are grounded in personal experience working on FOSS projects. They're also grounded in trust of the maintainers. In 5 years of full-time programming as a job and a hobby, I have found that to work t

The GPL says nothing about branding though. The GPL is about user freedom, the ability to let the user improve (and share improved version of) the software. In general, people tend to confuse copyright/patent with branding. The former

I mean sure. But I also need to parse UUID. And do other things with it. Even if I didn't need to, I'd still likely use the uuid-1345 crate for it. Here's the thing: If I import this code in my codebase directly instead of us

I maintain a package that has an indirect dep to macaddress because of UUID generation. UUID v2 is generated from Mac address + timestamp. My package only generates uuid v4 (fully random) and even if it was, the uuid dep doesn't expose

I've always found Qt and Python (PyQt and PySide) to be a weird match. So many times did I end up with cryptic segfaults in the python VM due to some python object being collected "too early", creating a dangling pointer in t

The packages themselves can't mutate, the nix store is read-only (except during installation). But some packages needs a global, mutable state (think databases), which is fine. What isn't fine is that some packages expect that mut

My recent venture in the filesystem have been somewhat fun. The problem isn't so much misnamed objects, and more that the kernel is filled with seemingly undocumented, arcane, old things. `sb_bread` isn't some kind of food, but th

The bar is very easy to set; dmca shouldn't apply if a monetary transaction happens from the host to the user. Because then the "user" isn't a user anymore. At that point, udemy and the user establish a business relation
