    You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. Made in Haskell!

    Hi everyone, I built a runtime to isolate untrusted code using wasm sandboxes. Basically, it protects your host system from problems that untrusted code can cause. We’ve had a great discussion about sandboxing in Python lately that elaborates a bit more on the problem [1]. In TypeScript, wasm integration is even more natural thanks to the close proximity between both ecosystems. The core is built in Rust. On top of that, I use WASI 0.2 via wasmtime and the component model, along with custom SDKs that keep things as idiomatic as possible. For example, in Python we have a simple decorator:…

    I built a CLI that detects patterns AI coding tools leave behind: empty catch blocks, hardcoded secrets, as any everywhere, comments that restate the code, god functions, SQL concatenation. 24 rules across JS/TS and Python. Zero config, runs offline, regex-based so it's fast. npx @yuvrajangadsingh/vibecheck . Also ships as a GitHub Action for inline PR annotations and standalone binaries (no Node required). Why: CodeRabbit found AI-generated PRs have 1.7x more issues than human PRs. Veracode says 45% of AI code samples have security vulnerabilities. "Vibe coding" is everywhere now…

    I built a cli tool that gets you started with TypeScript development with zero config. Initially created to solve my own problem but thought it might be useful for others as well. - SWC compiler - TypeScript type check support - Live reload support - .env file support - Path alias support - Typescript script runner - REPL support Please tell me I am not going down a rabbit hole.

    Hi HN, I’m Guillaume, the cofounder of Bearer, an Open Source SAST solution. After launching a few weeks ago here on Hacker News with support for Ruby and JavaScript stacks, I’m happy to report we’ve just released a new version (v1.2) with TypeScript support! In terms of code coverage, we use the same rules already implemented for vanilla JavaScript, but as usual, you can build your own. The rules list is here: https://docs.bearer.com/reference/rules/ It’s a first version for TS, but we believe that thanks to the pre-existing JavaScript support it should already…

    I made an open source, MIT license Typescript library based on some of the latest research that generates prompt injection attacks. It is a super minimal/lightweight and designed to be super easy to use. Keen to hear your thoughts and please be responsible and only pen test systems where you have permission to pen test!
