Here's a write-up for one of the bugs they found: https://red.anthropic.com/2026/exploit/

Crypto miners written in JS existed long before WebAssembly. Back then people also compiled large C++ code bases to (highly obfuscated) JS code and out of these heroic efforts grew asm.js which then evolved to WebAssembly. WebAssembly is a much better compile target than JS with more low-level types and primitives, but it's very similar to JS code in what it can and can't do in the browser.

Compiling a C++ application to megabytes of JS code doesn't make the result any more open-source or non-DRM than compiling the same thing to WebAssembly (you could translate Wasm to the equivalent but slower JS code).

Nice to hear from you! Yes it was a very reasonable choice back then, before (enormous) asm.js and Wasm functions.

The compiler wasn't really designed for these huge graphs, but fortunately a lot of the issues can be fixed incrementally and it's still holding up well.

The point is that Musk has been talking a lot about being a free speech absolutist. He even said this last month:

> My commitment to free speech extends even to not banning the account following my plane, even though that is a direct personal safety risk

And now he's banning accounts. That doesn't make sense for a free speech absolutist.

I think part of this is just time to get used to something new? You might notice some improvements too, for instance only after I started using Fastmail I realized the Gmail UI can be pretty slow and heavyweight although I never noticed this before.

This behavior is defined in the HTML spec, here:

> With Fastmail or another provider, you're trusting another corp.

You're trusting a corp that offers customer support, a service you pay them for. With Gmail you're completely on your own because you're only a small cog in the massive data mining machine. That's a pretty big difference.

That said, it's a good idea to set up a custom domain with a trusted registrar.

I migrated to Fastmail a few weeks ago. I'm really happy with it and I wish I had done it years ago. Many features. The web interface and apps feel a lot faster than Gmail.

Pro-tip: use a custom domain so that you can easily switch e-mail providers in the future without vendor lock-in. It's also very easy to add aliases in Fastmail.

> Plus after the import is finished, it will still periodically bring over any new emails received to the Gmail account.

Another option is to let Gmail forward your email to the new address.

> It’s a big deal and everyone who contributed should be super proud.

Thanks! We actually haven't really analyzed Speedometer (and most other benchmarks) yet with Warp so I expect this number to improve the coming months. The design seems to be holding up well and we're really excited about building on this.
