Porffor's rewrite has ~50% more throughput for Hono while using >10% less memory and Elysia v2 uses ~30% less memory with the same performance!
ALT Porffor branded benchmark graphs: hono (hello world): throughput: 120k -> 182k req/s (+52%) latency: 0.338 -> 0.250 ms (-26%) memory: 3.55 -> 3.08 MB (-13%) elysia v2 (hello world): throughput: 203k -> 203k req/s (0%) latency: 0.217 -> 0.220 ms (+1%) memory: 5.48 -> 3.73 MB (-32%)

Got all excited that Bloomberg wanted to interview me, only to realise it was a scammer trying to phish my account. Luckily, I was not born yesterday.
Anyway, if you do want a piece of me, Bloomberg, my door is open

Actually unbelievable that YouTube Premium costs £16.99/month in the UK while it’s just ¥1,680/month (£7.74) in Japan.

I do wish Rust/Cargo builds would use up an order of magnitude less disk space.
I was unable to contribute on the Windows side of React Native WebView because its builds used up 8 GB, filling up my 256 GB work laptop. I can't imagine needing 300 GB spare to contribute to Zed!

the more AI-written the codebase, the less likely it's monetizing

It is a pincer movement: first they caused a memory shortage and now they release an electron app.
Check mate peasants.
Ask yourself why OpenAI, with all the resources in the world to develop a native app via LLMs, still ended up migrating their feature-complete native app to Electron.

This is the hardest feature to find in all of the iOS settings.
Please set a stopwatch and tell me how long it takes you to find Conversation Boost. Good luck!

QuickJS is now passing 100% rusty_v8 and deno_core tests so we could swap out JS engine in @deno_land. Obv we're not gonna do that, but adding it as an option for `deno compile`d` apps is now feasible.
Trade runtime perf for smaller binary size. There's a ton of people who'd do it.
working on making the v8 crate engine agnostic.
looking promising - we might even have a JavaScriptCore / QuickJS flavored Deno soon

React Native WebGPU now support high depth bit onscreen colors on Android and iOS via getPreferredHighBitDepthCanvasFormat(). This is improvement will ship to React Native Skia too.

After 4 years, @deno_land no longer forks TypeScript.
TSGO in canary later this week.

Porffor is now self-hosted, meaning it compiles itself with itself! Not only is this a huge compiler milestone generally, it is also great for dogfooding and also unlocks some fun things further in the future.
This is made possible by Porffor's new rewrite, reducing its lines of code by >50% and making C output up to 5x more efficient! Here you can see the stats before and after the rewrite for Porffor itself:
ALT Porffor selfhost rewrite graphs, before vs after. bundle lines 40.4K→24.7K (1.6x smaller) bundle size 2.4MB→2.0MB (1.2x smaller) C lines 1.6M→289.0K (5.5x smaller) C size 70.4MB→12.3MB (5.7x smaller) debug compile time 5.0s→1.2s (4.1x faster) release compile time 143.2s→37.1s (3.9x faster) debug binary size 52.4MB→13.6MB (3.8x smaller) release binary size 14.1MB→4.6MB (3.1x smaller).
