Over 700 years. A tower originally built in 1310. The island it’s on is an exclave that is technically part of Hamburg.

Without some sort of reproducible builds (which are really finnickey to actually get) this doesn’t really help though. Adding some set of malicious patches before doing the binary release is trivial.

It’s good that LibreOffice exists and it can be a decent replacement for someone writing a simple document every once in a while. I can not take anyone seriously who claims it is anywhere near as good as the MS stuff. Recently I created a presentation in Impress and it was hell on earth. I ran into multiple bugs and handling formatting was just horrid working with the master/template slides (or whatever they are called) was essentially impossible.

Currently working with OnlyOffice which works better by a considerable margin.

600k seems a bit too much. That’s a fairly large city.

To clarify because this is always a point of confusion whenever the topic comes up. Telegram is, of course, transport encrypted. Someone listening on the wire cannot read your data. It is not end-to-end encrypted, meaning Telegram can always read your messages and can, in principle, give anyone access.

Blockchains have the property of being append-only, so a blockchain is precisely what makes it impossible to delete transactions. That being said, in a distributed system, once the message leaves trusted servers, it is obviously also impossible to delete it.
