Someone third-party made this twitter account x.com/uWebSockets It's not official 😂
At this point just treat everything on NPM as if it fell out of your pocket and landed in a pile of dog shit. The entire idea of non-exact version dependencies is BIZARRELY insecure. A joke.

The most common bug report, by far, in Bun is "segfault" aka memory issues. But they say Valgrind / AddressSanitizer (which are industry standard devices for finding memory issues) produce "false positives" and shouldn't be used. I've seen this play out a million times before.
Trend-following has ballpark similar returns as hold-only. But the catch is; buy-and-hold is dependent on hindsight as in, you're blindly trusting things will go up forever. If we picked a bad performing asset, buy-and-hold would be catastrophic, while trend-following would not.
This is the most well written & informed documentation of everything uWebSockets 👍deepwiki.com/uNetworking/uW…
@theo It's 2025 and people are just realizing scripts are way slower than native code.
Huffman coding (compression) is simpler than you think. It's just a binary tree where it takes more bits to reach less likely letters, than more likely letters. 1 = go right, 0 = go left, leaf node = you found your letter. So 'A' is 3 bits 010 Space is 3 bits 111
I implemented a #NetworkedAframe adapter and server based on uWebSockets. That thing flies, only 30% cpu compared to 100% with socketio server for 70 moving users. @aframevr

Update: Took about 10 days to completely replace AWS Api Gateway with uWebsockets.js Scaled via AWS Elasticache and regionalized. Just for keks did a comparison between both, uWebsockets based setup was much faster (RTT 150ms vs 90ms regional same AZ) Syntactically 1000x…

The architectural reason Node.js sucks in performance compared to Deno & Bun: Node.js implements each JS abstraction using the prior JS abstraction, maximizing overhead. Bun & Deno just implement the whole feature in native code and just expose it at your level of abstraction.
although I'm VERY impressed uWebSocket only uses 1.2mb memory running, I had to put it back where all C projects eventually belong...
How did uWebSocket got nearly ~550k req/sec 🔥🔥
uWebSockets.js is the fastest standards compliant & correct HTTP (RFC9110, RFC9112) server in TechEmpower's benchmark (before ban & removal). For non-pipelined benchmarks (the norm), it beats mrhttp by 83%. 💨 None of the top 3 are correct implementations (esp. not gnet, faf).
Bun's event-loop, TCP & TLS, Http & WebSocket server are all based on (forked from) uWebSockets & uSockets. It's not just the WebSocket server, it's practically everything networking I/O. uWebSockets.js for Node.js is still faster though (slimmer JS integration) 😏
