Show HN: AlgoDrill – Interactive drills to stop forgetting LeetCode patterns (Score: 150+ in 13 hours)
Link: https://readhacker.news/s/6H7hX
Comments: https://readhacker.news/c/6H7hX
I built AlgoDrill because I kept grinding LeetCode, thinking I knew the pattern, and then completely blanking when I had to implement it from scratch a few weeks later.
AlgoDrill turns NeetCode 150 and more into pattern-based drills: you rebuild the solution line by line with active recall, get first principles editorials that explain why each step exists, and everything is tagged by patterns like sliding window, two pointers, and DP so you can hammer the ones you keep forgetting. The goal is simple: turn familiar patterns into code you can write quickly and confidently in a real interview.

Would love feedback on whether this drill-style approach feels like a real upgrade over just solving problems once, and what’s most confusing or missing when you first land on the site.

🤯 Today I discovered a programming language I never knew existed…
One of my friends mentioned Idris in a discussion.
I got curious, did a bit of research — and wow… it’s amazing.
🧠 Idris lets you:
Catch serious bugs at compile time
Write programs where types prove correctness
Eliminate many runtime errors before the code even runs
It’s not mainstream, but it’s powerful and mind-blowing for CS students and devs who love correctness.
Ever heard of Idris before today? 👀
Or am I discovering it late too? 🙄 put your thought 👇

⚠️ 🔵 Denial of Service and Source Code Exposure in React Server Components
Security researchers have found and disclosed two additional vulnerabilities in React Server Components while attempting to exploit the patches in last week’s critical vulnerability.
If you already updated for the Critical Security Vulnerability last week, you will need to update again.
If you updated to 19.0.2, 19.1.3, and 19.2.2, these are incomplete and you will need to update again.
