Products that do what Distroverify – A tool to automatically verify hashes of any distro file does

Github Link: https://github.com/prahladyeri/distroverify Folks, I'm a distro hopper who mainly hops between ubuntu distros such as ubuntu, xubuntu, ubuntu-mate, etc. One thing I've found is the frequent need to verify the SHA1 hashes of the local and original version found on cdimage.ubuntu.com. Sometimes, you forget to verify the hash immediately and later, you have to again scavenge for that download URL in your browser history and then find the hash files URL, isn't it? For this, I've created a tool called distroverify that automatically pulls the corresponding…

    The pattern of downloading and executing installation scripts without verifying them has bothered me for a while. I started messing around with a way to verify the checksum of scripts before I execute them. I've found it a really useful tool for installing things like Rust or Deno. It's written entirely as a shell script, and it's easy to read and understand what's happening. I hope it may be useful to someone else!

    0github.com is a pull request viewer that color-codes every diff line/token by how much human attention it probably needs. Unlike PR-review bots, we try to flag not just by "is it a bug?" but by "is it worth a second look?" (examples: hard-coded secret, weird crypto mode, gnarly logic, ugly code). To try it, replace github.com with 0github.com in any pull-request URL. Under the hood, we split the PR into individual files, and for each file, we ask an LLM to annotate each line with a data structure that we parse into a colored heatmap. Examples:…

    Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

    I am the author of the platform, happy to reply to any question you might have! It scales up really nicely thanks to a year of research and development of the hashtable implemented in cachegrand, on the hardware used for benchmarking, an AMD EPYC 7502P, it was able to reach up to 5mln GET QPS and 4.5mln SET QPS, with batching up to 60mln GET QPS and up to 26MLN SET QPS. cachegrand is fast, it's fully Open Source, it's under a BSD 3-clause license - it can be used easily as standalone platform or incorporated in other ones without any licensing issue - and we are working to expand the Redis…

    Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…

    My partner reviews a lot of P&IDs (piping and instrumentation diagrams) and the adjacent files involved (excel, docx, pdfs, acd/l5x, etc). In his company, these are usually done in Bluebeam. It's really hard to see the diff + keep track of all the revisions resulted by these iterations. They end up storing files like "rev3_final_redlined.pdf". We've been looking for something close to Github to do these reviews, but haven't found one easy enough for folks with no CLI experience to understand and use (happy to check out more tools if you know any). So I built withkord.com to help with…

    I don't know Rust. Friday after work I realised that 90% of my IDE time now is just the commit/diff view — and even good IDEs feel heavy for that. So over the weekend I built a dedicated native tool for just that. Kyde is a macOS git commit + diff editor with one goal: be fast, do Git well. I'm curious whether anyone else mostly opens their IDE for git operations these days. It's open source, and there's a signed app in Releases.

    Hi HN, I'm Tyler Flint. Eight months ago we shared qtap here (https://news.ycombinator.com/item?id=43928118). Today we're releasing DevTools - a browser-based interface that gives you the Chrome Network tab experience for server-side HTTP/S traffic. The problem: You're debugging a production issue. An external dependency is returning errors. Your logs say "request failed" but not what was actually sent. Adding debug logging means redeploying and restarting services - which takes time and often changes the conditions you're trying to debug. tcpdump shows encrypted blobs.…

    This project is a tool for engineers who live in the terminal and are tired of losing their command history to ephemeral servers or fragmented `.bash_history` files. If you’re jumping between dozens of boxes, many of which might be destroyed an hour later, your "local memory" (the history file) is essentially useless. This tool builds a centralized, permanent brain for your shell activity, ensuring that a complex one-liner you crafted months ago remains accessible even if the server it ran on is long gone. The core mechanism wants to be a "zero-touch" capture that happens at the connection…

    Hey HN! We're Ayman and Dylan, co-founders of Nuanced (https://www.nuanced.dev/). We want to share a tool we’re working on to detect fake and real images: https://trial.nuanced.dev/demo/. The UI is bare-bones but you’ll get the idea. Drag or upload an image and our tool will display the probabilities with which it thinks that the image might be AI-generated or not. If you want, you can click “No, it’s AI” to confirm that the image was AI-generated, or “No, it’s real” to confirm that the image was not AI-generated. Why we’re working on this: as AI-generated…

    Pipe the output of a `diff` command to Diffswarm to get back a persistent URL that contains the diff with workflow, comments, search, etc. Basically some of the helpful features that Github offers on PR diffs, just available for any arbitrary diff. I wrote this tool to use at work for documenting snapshot diff triaging, and also used it to help with the same thing on a couple Ty PRs. Example: https://diffswarm.dev/d-01k2gknwyq82f6x17zqf3apjxc

    I was working on optimising Subversion. One of its bottleneck is computing file hashes. First thing I tried was to use OpenSSL for that. It significantly improved its performance. It made it 8x faster in some cases. However, it was not optimal to use it: - OpenSSL is heavy and bloated. It's like a whole operating system on its own. - Since OpenSSL 3.0, low-level digest APIs are deprecated, and instead they recommend to use EVP which might be slow in some cases. So I decided to create a new library for computing cryptographic digests. It basically takes OpenSSL's implementations, but with an…

    Ladies and gentlemen of a Lisp persuasion, Clojurians and Clojuristas, followers of the paren and everyone else covetously eyeing the greener grass, I made an open-source thing that I would like to share with you. My elevator pitch is that it'll make you forget all about regular print debugging in 10 minutes straight. The slightly longer pitch is this: #>(tag'n'trace any Clojure(-Script) form to `tap>` and Portal with automatic last-input function replay on eval, instant re-render and hassle-free insertion of traced data into the REPL) And before I end up pasting half the README here in bits…

    I built a GitHub app that detects it in pull requests, notifies or blocks them. Alongside it, I published a Semgrep ruleset for any stage of the CI/CD. I started this after getting frustrated by all the FUD around malicious code - lots of noise, little effort to solve it. Having said that, it's still a major attack vector - a stored RCE, with the codebase itself as the sink. Feedback is appreciated. The app, PRevent - https://github.com/apiiro/PRevent The ruleset: https://github.com/apiiro/malicious-code-ruleset The research:…

    We open-sourced the TLA+ and Fizzbee verified spec behind Ursa's storage engine. Verification across ~200K states caught a design bug that years of production missed. We then handed the spec to Claude Code — it produced a working Rust implementation (concurrent producers, compaction, fencing) without back-and-forth. We think verified specs are the best harness for coding agents: open-source the spec, let anyone implement it.
