Hello hello
What's up  party people? Next week is the first quarter of the new moon, so keep your eye out for that. What does that mean? No one knows what it means, but it's provocative.

I just wanted to say that if you have the ability to support this newsletter, I'd really appreciate it. I haven't had any ads, and probably won't for a while (maybe never if there are enough supporters), so putting in the one to two hours per issue to curate the articles and write the summaries is a pretty high cost. On top of that (although minor in comparison to the time) is the cost of hosting and using Mailchimp. You can support it on Patreon or send me some ETH to 0x82305bcc5C30867C008D25F64F6FCf7f6dA1aa45.

Anyway,, have a lovely weekend and here's the issue!

Well in this enlightening article, Arun Sai Krishnan presents Dropbox's custom built solution for achieving exactly that. Arun outlines the requirements, architecture, data model, lifecycles, and how they achieved guarantees for such a monstrously large system.

GPU programming has grown a lot in popularity in recent years, primarily because of its application in many calculation intensive processes like rendering or machine learning. One of the inherent difficulties of programming on a GPU is one of the reason why it's so popular; parallelism. In this concise article, Kostas Anagnostou explains how a not uncommon issue in programming in general, waiting for data, is mitigated using parallel task assignment. Kostas also brings up an important point about finding the balance between batch quantity processing and waiting.

Migration, it's a big part of the natural world, and it's a big part of programming. What can we learn from the Arctic Tern and its 71,000 km annual migration? Well in this exciting article, Pablo Polvorin doesn't mention it at all. Pablo actually talks about how a recent Erlang migration led to a drop in the system's performance, and key points on narrowing the problem down and finding it with focused research. and implementing the solution.
