You'll find a lot of blog articles on the subject, too.

Many simply result to switching to jemalloc since it handles allocations across multiple threads more efficiently, with less fragmentation.

PSA to #rustlang and #linux developers: there is a long-standing 20y bug in the system allocator (glibc malloc) which causes it to hoard large sbrk buffers in arenas. By default, it uses heuristics to dynamically increase the mmap threshold—the point where it switches from using sbrk to mmap—which causes a memory "leak". Some #libcosmic apps were affected by this bug, causing them to use 10-30x more memory than they need. See the PR below for how to tame malloc in Rust:

@aral @ragectl @katzenberger No, it sheds light on your desire to falsely accuse volunteers of doing things they aren't.

Fedora is not Red Hat or IBM. It is a community project that is sponsored by Red Hat. Same goes for most Linux projects: community-driven with some sponsored contract work.

If you actually cared about accessibility, you wouldn't be here bullying people with virtue signaling. You would be getting involved and sponsoring accessibility work. That's how open source works.

@aral @ragectl @katzenberger System76 isn't dying on any hill. We have been committing part of our COSMIC resources to accessibility work so that COSMIC will have functioning accessibility on release. In fact, we are currently in the process of upstreaming our AccessKit work from libcosmic into iced right now.

At the end of the day, complaining about problems on here won't achieve anything. If you want to see improvements in accessibility, then do what we're doing. Contribute, submit PRs, etc.

Quoted the blanket statement.

Not only that, but the post complains that a Fedora maintainer said that patches are welcome, and yet the first instinct in response to that is to want to block them? Not a productive attitude.

If you care about the problem, then instead of calling people abliest, go help the people who are working on this problem. GNOME is backing AccessKit, which will be in COSMIC.
