   Build your own Git/Docker/Redis (advanced programming challenges)▲6

   Hey HN! I spent the last year building a programming challenges site targeted at intermediate/advanced programmers [1]. Challenges follow the "Build your own X" format, where you learn about a popular open source tool by building a small version yourself (popularized by this Github repo [2]).

I've posted about this multiple times here before, but haven't managed to gather much interest. Trying…

    My weekend project to learn Javascript - 'Pinterest for Hacker News'▲95

    We launched Hackerest last week. We’re a group of security engineers based in Italy (ex-Amazon, Accenture) who spent years doing pentests the traditional way and kept wondering why the workflow still looks like it did in 2010. Most pentests today (still) work like this: 1. the engagement runs for days or weeks 2. nothing is shared until everything is finished 3. the client gets a PDF long after the issues were actually discovered 4. half of the attack surface has changed by then What Hackerest does: * findings appear in real time during the active testing window, as testers discover them *…
