go-binsync – Go binary patches up to 67× smaller than bsdiff

This project is a little performance-optimization experiment focused on reducing the size of Go binary patches, which can be useful for quick incremental updates of live services. When a Go program grows by a few bytes through an incremental change, a bunch of related references and offsets throughout the compiled binary end up changing that makes general-purpose binary-diff encoders inefficient: `zstd --patch-from` produces a 530kb patch for a one-line change in a 30MB binary. bsdiff improves upon this (150KB patch) thanks to a delta compression algorithm that can handle relative offsets.…

    I've created a powerful tool to help Go developers uncover the hidden giants in their compiled binaries. Go Size Analyzer is like an X-ray machine for your Go executables, revealing: Which dependencies are eating up your binary size Unexpected bloat from standard library or vendor packages Size changes between binary versions with a visual diff Key features that set it apart: Interactive treemap visualizations (check out the demo: https://gsa.zxilly.dev) Slick terminal UI for deep diving into package hierarchies Cross-platform support (works on Linux, macOS, and Windows binaries)…

We are building `pcz` to provide a reimagination of Go the language, in an effort to make it suitable for all kinds of programming tasks, and currently you can use it to build efficient web applications in Go using the generated Web SDK (as shown with the live web demo[1]). The journey is just starting, any suggestions? or any critics? [1]: https://primecitizens.github.io/livedemos/10-plat-web/

    We scaled Git to support 1 TB repos2022 · xethub.com · ▲279

    I’ve been in the MLOps space for ~10 years, and data is still the hardest unsolved open problem. Code is versioned using Git, data is stored somewhere else, and context often lives in a 3rd location like Slack or GDocs. This is why we built XetHub, a platform that enables teams to treat data like code, using Git. Unlike Git LFS, we don’t just store the files. We use content-defined chunking and Merkle Trees to dedupe against everything in history. This allows small changes in large files to be stored compactly. Read more here:…

  • go-nbd – A Pure Go NBD Server and Client2023 · github.com · ▲113

    Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :)

  • Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  • Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
