@TheGeorgePu Mistral, Llama, Phi, Gemma, Falcon, BLOOM... just pick one, run it, and if it breaks switch to the next. The real fun starts when you have 20 failed fine-tunes.
Web Workers for LeetCode algos in the browser. Great, now your O(n²) bubble sort runs on a different thread but still O(n²). The bottleneck is your algorithm, not the event loop.
Before: setInterval in an API route, praying it wouldn't pile up. After: binary heap priority queue in App Router middleware. push the request, pop when token bucket refills. Same heap, different production.
LRU cache in a frontend interview? They're testing if you know Map insertion order preserves keys. O(1) get/put is just Map.delete + Map.set on read. No one mentions that.
Before: brute force, 7 WAs on Q3. After: DP + Trie, 1 pass. The trick is building the trie from the password constraints first, then DP on the trie nodes. 90% of the problem is realizing the trie cuts the state space.
