I've spent the last few months working on this codec. It has the following characteristics: - SOTA decompression throughput in its ratio class - Decent ratios (comparable to LZ4 at high effort levels) - Slow compression Most of the gains can be attributed to reducing branches and making decompression very friendly to out-of-order cores, by using a smart format. Results on the tarred Silesia corpus on Intel x86-64 follow: codec decode ratio encode misa77 -0 5219 MB/s 42.64% 54.5 MB/s misa77 -1 42

Dear HN, I have a question: Does it still make sense to write code purely by hand? Let me clarify. First of all, I'm not talking about environments where you need to "move fast" or where your required to use LLMs. I'm referring more to an environment where you do it on your own terms, rather than on the terms of the employer. Secondly, I'm not talking about prompting "Build me the next twitter clone", but rather prompting very small tasks after you have made the initial design, something along t

Hey HN, we’re Nitish and Prateek, the founders of Coasty ( https://coasty.ai/computer-use ). We’re building computer-use agents that can complete workflows inside legacy desktop software and web applications without usable APIs. Developers send Coasty a natural-language task either through our consumer app or through our API, select a machine or browser environment, and any relevant credentials or files. The agent then operates the interface through screenshots, mouse, and keyboard input, verifi

Hi HN! I've posted SirixDB here before, back in 2019 ( https://news.ycombinator.com/item?id=19834681 ) and again in 2023 ( https://news.ycombinator.com/item?id=38252963 ). The core idea behind SirixDB is, that history is a first-class citizen. Every commit stores a lightweight, queryable revision. You can query any point in time, even individual nodes (for instance JSON values), diff arbitrary revisions, and efficiently track how data evolved without replaying events. Unlike traditional event st
