What Hacker News says?
Hey! I'm a Sublime Text user since ST2 in 2011. I love ST (my last blog post is https://blog.separateconcerns.com/2025-01-04-teal-lsp-sublim... ) and I think the main thing lacking compared to the competition is the remote development experience. I work in AI so we typically work over SSH on machines with big GPUs. Most of my colleagues use VSCode because it has a very good Remote Development extension.

HN discussionSame here! I blogged about it over 5 years ago (time flies) [1]! Amusingly, despite having done a ton of Computer Vision (I worked for an image recognition company for 4 years) I never used it for that purpose. The main practical use case I had was related to the use of Trellis modulation [2] for band-limited communication channels. [1] https://blog.separateconcerns.com/2013-03-03-viterbi-algorit...

HN discussionI used WebOS, and I agree. I really enjoyed my Pre3. I could never bring myself to like Firefox OS. The best now is Jolla, which I don't think has failed at all yet (I have a Jolla C, I wrote about it shortly here: https://blog.separateconcerns.com/2016-09-16-thoughts-1.html ).

HN discussionFor people not already into distributed systems but want to get started, I blogged my (very) short list of things to read last year [1]. Today I would add a fifth item to that list: "Why Logical Clocks are Easy", which is one of the best explanations of causality I have seen so far [2].

HN discussionI wrote a blog post advocating for something like this recently, with an additional push to notify the client when it should poll: https://blog.separateconcerns.com/2022-03-05-push-to-poll.ht... I wasn't aware of this but it fits the use case perfectly, I will update the post.

HN discussionI have mixed feelings about this. On the negative side, Mike Pall is an impressive individual who has contributed a lot to the field of JIT-compiled languages, so losing him is obviously bad for the project. LuaJIT is also a hard codebase to get into, I myself tried to get into it and gave up (I blogged about it last month [1]). There are probably still parts of it that only Mike understands, I guess we will see how…
