Explanation of the last panel?

Tell us the horrors then, i had ants in a dirty Italian hostel once, but no bugs in a clean place like this

Makes sense

What’s an example use case for this? Not criticising, i seriously cannot think of anything.

You should be good with just a VPN. Tor over VPN (not the other alway round!) makes sense if you want to hide your use of Tor from whoever is watching, and especially if you use Tor Browser for something you want to hide, the timing of when you open and close Tor Browser could be correlated with the thing you’re doing. Overkill for just watching videos in privacy.

Welcome to the school system

We rarely cook together, but when we do, one person does prep and the other cooks, like in a professional kitchen. Eliminates a lot of tension.

Yeah that’s for online payments. Cash stands strong where I live but they’re working on it, many chain stores have plenty of card-only self-checkout machines and a single cash register with a long queue.

EU is outlawing non-KYC methods of payment in 2027. It will be a crime to accept an anonymous/gift visa card. They’re not issued in the EU for many years now, but now accepting foreign ones will be outlawed too.

I don’t recall anonymous PO boxes or bank accounts ever existing here. At least parcel locker pickup still works without KYC, but the media is already preparing ground with stories about drugs and terrorism.

It was so widespread that around 2004-2005 you could buy dvd players that supported avi/mp4 files with external subtitles. They don’t create products like that for niche markets.

It can not, at least here in the EU the governments are actively fighting the ability to make a purchase without leaving your full personal data set. KYC-free businesses exist but are increasingly regulated to be full-KYC.

Strong Amiga coding vibes.

I’m sure implementing floating point directly in bash would work great

Haha nice! How long did it take you? Integer-only math?

It’s a smard card, there’s no reason why the “yes” can’t be cryptographically signed with a government-approved certificate.

That being said, fuck age verification online.

I suppose you skipped the part where he discussed his classmates’ reaction? That one brings many memories of showing off my own projects.

Thanks, nice pics in your profile!
