Code Review Lab – Practice spotting vulnerabilities in code
I built Code Review Lab to help engineers practice secure code review skills. Many friends looking to switch into AppSec struggled with interview code review exercises. While there are great resources for other interview types, I couldn't find a good platform focused specifically on secure code review. The platform offers interactive challenges where you review actual vulnerable code snippets (Go, PHP, etc.) and identify the exact lines with security issues. Each challenge includes context about the application and hints to guide your learning.

What it does
Improve your cybersecurity skills with interactive code review challenges. Practice identifying security vulnerabilities across multiple programming languages.
Build the instinct that catches vulnerabilities before they ship. Review realistic production code, choose the vulnerable line, and learn from the explanation. PixelVault is a design-portfolio SaaS where creatives showcase their work. A popular feature lets users import a brand logo straight from a URL so they don't have to download and re-upload assets. The engineer who built it read up on command injection and was careful to never use a shell, passing arguments as a list instead. Review the import pipeline and decide whether that precaution isfrom codereviewlab.com

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.…

Hey HN. We're Mus and Isaac - creators of LightLayer. We've been outputting a ton more code since using agentic dev tools. It's been great. But we're starting to see a new bottleneck emerge that's no longer writing the actual code: reviewing code. We’d love to hear from folks here if they’re feeling the inertia of code reviews a lot more these days with the surge in development velocity. For us, it was the reason we decided to pivot what we were working on before, and go full-time on building a workspace aimed at bringing the code review experience up to speed for the AI era. To be clear:…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
