Rust at Scale: An Added Layer of Security for WhatsApp

The differential fuzzing approach is clever — way safer than a big-bang rewrite. Running both versions in parallel to catch edge cases before switching over is how you actually ship rewrites without breaking production. The 160k to 90k LOC drop is impressive, but the real engineering win is the validation strategy.

On binary size, static linking with LTO should handle most of the bloat without needing custom stdlib builds.

We really need an AI filter here on HN.

A comment like this works as well, let the community do its thing.

There are a couple of bots here.

Quoting a user:

    keeping it simple: a flat $15,000 to get you on the front page of Hacker News.
    [...] contact e-mail below

Expensive, but now with LLMs it's super cheap to do.

Spend a week to do a bot, get 10'000 USD of ARR for your B2B tech SaaS, and applause from your investors.

And a week is probably exaggerated, 2 days max

Do you have any actual evidence that these types of services are being offered for that type of price point, though?

The reason I'm asking is that I actually believe the price point is much lower. It's probably much easier to get on the front page of HN of you time the submission + upvotes well enough.
