I like this thinking about other people's time as opportunity cost. I do that a lot and always encourage others to keep it in mind, too.
An example: a few years ago, there was a recurring unnecessary traffic congestion on my commute because of a malfunctioning traffic light. On the third day, I did some numbers while waiting and came to the conclusion that over hundreds of people, this was quickly adding up to months of lifetime wasted in total.
I then called the responsible municipality right on the spot to notify them there's a problem. They thanked me and had it fixed the next day.
Me and some friends used to attend the CCC some 15-20 years ago. Back then, we just showed up at the entrance on the first day and bought our tickets there.
This year we were toying with the idea of going for a revival. But man, did we underestimate how much this event has grown...
Tickets in the second presale round were gone within 1-2 seconds. We didn't stand a chance. I feel like we failed the entry exam tbh.
Anyways, to everybody who did score a ticket: have phun, and happy hacking!
The easy way to get tickets is via local hackspaces that are somewhat (not necessarily formally) associated to the CCC. There is a ticket contingent for people active in and around the wider chaos community that gets distributed via the hackspaces. They all handle things slightly differently, but the way to get tickets is usually to show up at a hackspace once in a while (or knowing someone who is active there) and getting tickets from there in the presale phase.
The other guaranteed way for tickets is to volunteer enough as an angel at the Congress the year before to get an angel voucher. But you obviously need a ticket for a Congress in the first place do to that.
I've one ticket for sale (€190-255), since I bought two tickets (one € 255 supporter for myself and € 190 for partner) but also got a speaker ticket (https://fahrplan.events.ccc.de/congress/2025/fahrplan/event/...), since speaker announcement was after the first round of sales via vouchers.
So let me know if someone is interested in this ticket, see my GitHub for mail address. I know other speakers where even unaware of this (so I might know another ticket for sale).
Tickets are sold (to the first email that arrived at 10:25 CEST, and the second ticket of a friend who's also a speaker to the second mailer at 11:11 CEST).
Since 22C3 I really enjoyed watching online and chatting with a small irc community about it. I had this notion that if I ever lived in Europe I’d go myself. Well for the last three years it seems I haven’t gone - the ticket situation was a shock at first but makes sense. The number of unrecorded talks does feel like it’s gone up though which has been regrettable.
If you're looking for a similar event, you might want to check out GPN - Gulaschprogrammiernacht (https://gulas.ch).
It skews a bit more German, but it's essentially a smaller "summer congress" that used to have free attendance until this year (tickets now cost 10€ to cover the breakfast, IIRC). A lot less people there, but the general vibe is very similar.
If you still have old friends from those times, ping them and ask if they have any tickets for friends. Most times I've gone, it's been via local/social associations and people I've known from those, only managed to buy a ticket once, but it's short of impossible normally.
I was just about to say the same: OpenSCAD is CAD for programmers. It's very different from what's generally considered "CAD".
That's not necessarily a bad thing; there's a clientele for it, especially here on HN. But as a mechanical engineer who's used quite a few industry standard CAD systems, I'm sorry to say I wouldn't touch it with a ten foot pole.
Funnily, just a few days ago I tried FreeCAD, and found it to be better than I had expected.
Is that due to some kind of issue with the architecture, or just a matter of software support?
In the latter case, I'd expect patches for AMD or Intel to become a priority pretty quickly. After all, they need their products to run on systems that customers can buy.
Presumably you mean Intel’s integrated GPUs? They do have the Arc line of discrete GPUs now, and those are a bit more than a frame buffer with a clever blitter.
