I mean, it's not as if Libreoffice was created yesterday. Its predecessor OpenOffice is now 25 years old. Your question becomes: Why did you choose the expensive version where you never know what it will cost next year in the first pla

I have seen takes about the environmental footprint of unused data before, and I have severe doubts this is a relevant issue. I mean, sure, there is some impact. Storage media has to be produced. But there's a reason storage is cheap,

No, a Quantum RNG does not solve the issue that people use an API for insecure random numbers when they should use one for secure random numbers. Every OS already has a secure RNG API. That's a solved problem.

Technically correct, but the RNGs you're mentioning are essentially RNGs build on public key cryptography. And I don't think they're widely used, simply because they're slow and have no advantage over faster ones (the Du

His point was that he was working on a product that solves no actual problem. Quantum RNGs are gimmicks that are sold as a solution to a security problem. But they don't solve any security problem. There are real security problems with

I don't want to start any wars either, but I think people should make informed choices. By choosing OpenOffice, you should be aware that you are at an increased risk for attacks. One of the consistent problems with OpenOffice over the

This is missing the point. To be clear, I'm not necessarily a fan of DMARC, particularly how it was introduced. But it is very obvious that spammers will eventually do everything to not be flagged as spammers. What DMARC gives you is t

I think it's clear that factoring works if you can build a scalable quantum computer . But: 1. It's a very lonely example. 2. It's not clear how big the market is for "you can break encryption from the past, but not cur
