I like rust, I write go. There was a thread here the other day where a rust dev pointed out that "Rust is the language tokio ate"... https://nullderef.com/blog/rust-async-sync/ Rust is a lot of overhead when go is "good enough" for 99% of what needs to get done. That doesn't mean go is good for everything. I would still rather write Rust than C or C++ or bunch of other languages. Look at a project like Pingora, from…

HN discussionI've been thinking a lot about how to have healthier relationships with our phones. There are already dumbphones, but they're quite extreme and not everyone is willing to switch. So I wonder if there's anything else that could be done in between. Investigating and writing on my blog ( https://nullderef.com ) has been super fun so far.

HN discussionNovember is my last working month! I'm giving entrepreneurship a try to solve a huge problem: phone overuse. It's been busy: - Reading books, currently "The Mom Test" - Looking for a startup community and being disappointed with what my city has to offer - Deciding between VC vs. bootstrapping, and taking a firmer stance to try the latter first. This includes rejecting ODF. - Talking with like-minded people. I now h…

HN discussionYou are skipping the massive point here. If you are using a library in rust, it has to be async await, tokio, send+sync and all the other crap. Or if it is sync api then it is useless for async application. This approach of passing IO removes this problem and this is THE main problem. This way you don’t have to use procedural macros or other bs to implement multi versioning for the functions in your library, which d…

HN discussionAmber Case is awesome. I'm personally building a silly app that makes it annoying to use social media. It will sometimes display cookie banners, cats, and more in the middle of your screen :) https://nullderef.com/blog/phone-jan25/

HN discussionI think there's a reasonable motivating example at https://www.chiark.greenend.org.uk/~sgtatham/coroutines.html , but not a reasonable implementation. A reasonable implementation for C is at https://github.com/creationix/libco and for Zig at https://github.com/rsepassi/zigcoro . For a real world example, https://github.com/alexnask/iguanaTLS is a TLS library written in terms of the stdlib's reader and writer interfa…

HN discussionCancellation isn't possible in general. For example, if you've kicked off expensive work on another thread or passed a pointer to your future to the kernel via io_uring, you must add a layer of indirection that's quite similar to a cancelation context. You can't just accept that the expensive work you don't care about will keep happening or resume a future that has been dropped when the cqe entry bearing a pointer t…

on “Asynchronous IO: the next billion-dollar mistake?”Submitted Plugins in Rust: Diving into Dynamic Loading as a story · 3 points
HN discussion> I feel a lot of this async criticism has more to do with how async is used than with Rust itself. Maybe it would be good to have more crates that don't used async or even depend on tokio, but in the end this is on us as a community. No, this is a language design issue. In Lua or Zig the easy way to write a library that speaks websockets produces a library that works with synchronous or asynchronous i/o and with th…
