    I've long had a dislike for leetcode interviews on both sides of the coin. Project-based interviews can also be challenging because it can end up filtering out folks who don't want to spend several hours building something in their free time. I met up with a friend last year -- a very senior dev -- who had taken some time off to study leetcode exercises while preparing for FAANG interviews. It struck me that one of the key measures of whether a candidate is a fit for a team is rather synthetic. CodeRev.app is a simple, lightweight tool that helps teams evaluate candidates using code reviews.…

    I built a web-based app for building websites. The main unique features are: 1. The ability to copy and paste any HTML and CSS into the editor with no limits. I was never able to find another app that could do this without some form of limitation. 2. CSS filtering, which means you can click on an element to view and edit the CSS selectors and rules that apply to that element alone. In many cases I've found CSS naming conventions like BEM to become irritating at certain scales, so this is an alternative solution. This part of the app needs some more development work but the concept is there.…

    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 HN! I've just released CSS Studio, a design tool that lives on your site, runs on your browser, sends updates to your existing AI agent, which edits any codebase. You can actually play around with the latest version directly on the site. Technically, the way this works is you view your site in dev mode and start editing it. In your agent, you can run /studio which then polls (or uses Claude Channels) an MCP server. Changes are streamed as JSON via the MCP, along with some viewport and URL information, and the skill has some instructions on how best to implement them. It contains a…

    Hi Hacker News, We're Bryan and Richard, cofounders of you.com. Together with our team of engineers, we are working on YouCode, a search engine for people who code. You can try it at code.you.com. The main idea is to make the search experience better and more efficient when coding. We’d love your feedback for a few use cases that we have in mind so far: * searching through StackOverflow for quick code snippets: reverting a git commit for example [1] * searching through GitHub Issues: when you’re getting an error message that looks unfamiliar [2, 3] * searching through the documentation for…
