g.co, Google's official URL shortcut (update: or Google Workspace's domain verification, see bottom), is compromised. People are actively having their Google accounts stolen.

Someone just tried the most sophisticated phishing attack I've ever seen. I almost fell for it. My mind is a little blown.

Someone named "Chloe" called me from 650-203-0000 with Caller ID saying "Google". She sounded like a real engineer, the connection was super clear, and she had an American accent. Screenshot.
They said that they were from Google Workspace and someone had recently gained access to my account, which they had blocked. They asked me if I had recently logged in from Frankfurt, Germany and I said no.
I asked if they can confirm this is Google calling by emailing me from a Google email and they said sure and sent me this email and told me to look for a case number in it, which I saw in

JavaScript LRU library benchmark

There are too many LRU(Least Recently Used) implementations in JS.

I recommend to use [flru] which is the smallest one and fast enough. Unless you need more rich functionality.

However, it's performance is vary depend on the host environment. For example, flru loses on Bun.

If you need micro-optimization on it, measure it yourself in your environment.

Encrypting data with AES128 in JavaScript

Usage

AES128 uses a 16 byte secret key.

const key = new Uint8Array(16);
crypto.getRandomValues(key);

Example:

function Form() {
  const [isPending, onSubmit] = useFormActionHandler((formData, reset) => {
    if (formData.get('condition') === 'X') {
      reset();
    }
    // ...
 });
