Doesn't Google use mostly C++?

> There's a reason why every major tech company has developed its own distributed filesystem

I haven't worked at FAANG, but is this a well-known fact? I've never heard of it. Unless they're referring to things like S3? Are these large corps running literal custom filesystem implementations?

Or, at least, that’s how it would work if it wasn’t for SNI…

Signal has a central, proprietary server. It's between impractical and impossible to run your own Signal server like you can with Matrix, Revolt, or Delta Chat for example. BlueSky has a similar approach (compare to Mastodon).

Also Signal requires a phone number to sign-in. It's not exactly private. AFAIK the proprietary server can glean your IP, your phone number, who you talk to, and when you talk to them. This type of metadata is valuable information.

The WhatsApp co-founder gave Signal $105M in 2018. Signal costs ~$50M/year to run. It's also funded by wealthy donors such as Jack Dorsey (Twitter, BlueSky, Square). BTW Jack is now pushing Signal to integrate Bitcoin.

When evaluating the "ethics" of a chat platform, we should factor-in the metadata, soft power, and eventual leverage that centralized (controlled by a few) platforms like BlueSky and Signal afford to wealthy folks who are bankrolling it.

Are there settings you can apply to Signal that make them compatible with record retention laws?

PHP was blamed for a good reason: for a long time it did not by default support prepared SQL statements. You could install the mysqli extension to gain such support but that was almost never available on shared web hosts.

Nice work! Too bad it's GPL v2 :(

You can’t change the seed phrase for a derived wallet. You’d have to create a new one and transfer the assets.
