This is how you properly calculate an element from the Fibonacci sequence in JavaScript:

function fibonacci(n) {
const phi = (1+Math.sqrt(5))/2;
return Math.round((phi**(n) - (-phi)**(-n))/(2*phi-1));
}

fibonacci(1000)

This is much faster than your recursive Rust solution! That means JS is faster than Rust!

NEW! Fastly's HTML Rewriter is live in the JS SDK (v3.35.0) for Compute.

It's a native, streaming parser that lets you modify HTML at the edge with CSS selectors—and it's ~20x faster than old-school DOM buffering.

Say goodbye to origin strain. Say hello to instant personalization.

Looks like blockchains have finally found a serious use case, just maybe not the one predicted/hoped for...

This article is about #Glassworm, the latest major exploit in JavaScript-land, targetting VSCode and using #Solana as command infrastructure and Google Calendar events as backup. It's full of novel attack techniques and as they say in the article themselves: "this is absolutely brilliant (and terrifying)". All in all, a different form of "creative coding"...

"The malware is hunting for credentials:

- NPM authentication tokens - to publish malicious packages
- GitHub tokens - to compromise repositories
- OpenVSX credentials - to inject more extensions
- Git credentials - to push malicious code
- 49 different cryptocurrency wallet extensions - targeting MetaMask, Phantom, Coinbase Wallet, and dozens more"

I still find funny how people are still trying to replicate #Apple's Liquid Glass UI from iOS 26.

Those who try to make a simple or performant implementation end up with something "not quite" Liquid Glass.

Those who try to replicate it 1:1 end up with their computer blown up.
