All talks will be live streamed, and right after the talk is done you have a rough cut available instantly under "re-live" you can watch until the final recording is available; https://streaming.media.ccc.de/39c3/relive
I should note that some talks will not be recorded, and only available at the congress. These are clearly marked on the congress hub website, but not easily available on the fahrplan view.
Ah, the filterable schedule would be even better if you could filter on multiple categories at once. I just want security/hardware/science, and then I would have to constantly switch around, which is worse than looking at the full schedule with the other categories included.
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!
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).
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.
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 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.
Personally I'm most excited about "Don’t look up: There are sensitive internal links in the clear on GEO satellites" with Nadia Heninger & Annie Dai. Harald Welte's "ISDN + POTS Telephony at Congress and Camp" covers how they're doing telephone infrastructure at congress/conference itself, and will surely be interesting too:
> Just like at this very event (39C3), the last few years a small group of volunteers has delpoyed and operated legacy telephony networks for ISDN (digital) and POTS (analog) services at CCC-camp2023 and 38C3. Anyone on-site can obtain subscriber lines (POTS, ISDN BRI or PRI service) and use them for a variety of services, including telephony, fax machines, modem dial-up into BBSs as well as dial-up internet access and video telephony.
Some of the more "celebrityish" talks tend to be popular by reputation, but content is often reused a lot, e.g. "10 years of Dieselgate" kind of falls into that. Watched the original, and the followup, and I think also the followup-followup, eventually it's worth checking out new topics instead, even though the presenters could not be faulted in any way.
Yes. They record almost every talk. You’ll find the relive (unedited recording of the live stream) on https://media.ccc.de and some time later the edited recording also on media.ccc.de and also on YouTube.
There also also live translations to English (and some other languages) for talks in german.
It ends at 1am their time. The conference itself never stops there are people there around the clock. (I wish I could go!! I went to 28c3 in Berlin and 29c3 in Hamburg they were amazing)
Probably. In previous years there were streamdumps available immediately somewhere (though figuring out where took me usually a day or so) and a re-live version on media.ccc.de a bit later. (Usually hours, but from time to time a day or so.)
Hacking and politics was always deeply intertwined in Germany/Europe. Especially the CCC has always been at least as much a political organization as it is a hacker community.
Hey, at least you can reasonably argue that the political content has been headed downhill since the more aggressive days of the past. Do we see wikileaks or the likes anymore? Not really.
Without direct action it's just nerds reading out their blog posts about politics, which couldn't be less interesting.
The user had more arguments than just "it's all politics". What level of scrutiny does his statement have to hold up to? Because as far as I am concerned this is not here to find scientific truths.
I don't know man. It's always the same debate: It's either "too much politics" or
"no change at all" whenever this issue comes up and the "nothing changed" crowd keeps on reminding everyone that C3 "was always like that". I'm not requesting a scientific study but if you're this convinced that nothing changed despite may old school attendees chiming in to confirm the opposite, perhaps it would be helpful to compare old and new schedules.
I find it strange you didn't latch on to the original comment, which has the exact same problem you complained about, but reacted to the response. The best action is to ignore threads and sub-threads you don't care about and leave others who do to their fun.
this wasn't the point ... the point is that the whole thing is getting more and more political and less technical and fun.
I was at the camp and some congresses in the past and they where always fun but nowadays it seems like it's like a political movement event for certain strands and ideologies and way less fun and interesting things (thou there are gems) and it seems that you have to think a certain way or at least accept certain positions even if it's not your position because otherwise you are silly or something else.
IMHO, CCC is completely defanged as a political institution. They went along with contact tracing because the local app was open source and somewhat secure and many of the regulars in local spaces people will cause lots of drama if you don't wear a mask in 2025.
Most local hackerspaces I visited are basically green and leftist queer safe spaces where adults run around with stuffed animals. If that's what you're looking for, great, I'm not judging, it just doesn't click with me. I used to visit hackerpaces during my travels but regardless of how open and kind I approach a new place, once they ask me to mask up or inquire for my pronouns things just don't end well, even if I'm really polite in explaining my position. That's not the tolerance and open mindedness I encountered around 2009 during my first C3.
Still, I wish everyone attending the best of times. There's so many people there that I imagine you'll be able to find the right folks if you're there and look around.
Not looking for a debate or inciting hate towards anyone here.
Culture changes. Hacker culture in Europe changed too, young people are moving up and taking positions in local organizations. You didn't change with it, and you're not open to accepting that change, so you are feeling out of place - that's simply how this works.
A lot of those people will feel welcomed and will be treated with respect that they don't usually get everywhere else. They decided to embrace that, it comes at a cost - like you feeling weirded out and not showing up - but they're probably fine with that being your problem to figure out.
I've moved on, all good, change is perfectly fine. I just think they lost something that made CCC special. Got my own decentralized trusted circles now. I think I made it quite clear that I wish anyone still attending these events and spaces all the best regardless.
CCC always has been explicit far left/green, looking at its history, as other people in here have mentioned.
I think it would be fair to say that the club as a whole has become more open about that, I think that's more owed to a lot of folks driving initiatives feeling like the walls are closing in on them though and I can't exactly fault them for that :)
I can fully relate ... back in the days there wasn't much (at least I don't remember) of "this kind" of ppl and everything was just hacking. However I can imagine what you mean.
At the end this growing craziness does not change any time soon so you are right ... "finding the folks that fit you" is maybe the best advice (and this hasn't to be the CCC).
Fortunately the interesting talks are often recorded so nobody has to attend who don't want in order to get the interesting stuff.
Yeah, it's really not wierd that people thinking that using secure technologies, firewalls and privacy to defend against infections on their electronics would also strongly support using a firewall to defend themselves from disease in the physical space.
The fact that your opinion usually comes together with other incompatible political opinions of folks that's been running those spaces for decades doesn't help either.
They didn't change. You however became something they always despised.
>it's really not wierd that people thinking that using secure technologies, firewalls and privacy to defend against infections on their electronics would also strongly support using a firewall to defend themselves from disease in the physical space
On the other hand, there is a discongruency when people who are against control and surveillance start implementing control and surveillance because the particular purpose sanctified the means. Something that previously seemed non-negotiable, culturally fundamental even, was toppled.
You just gave the best example of how these interactions usually play out. You know basically nothing about me and yet you assume to know exactly "what I've become" and that I deserve to be "despised" based on 2 statements that don't tell you anything about me because I never explained my positions in depth.
I spent more than a decade in and around 2-3 local hackerspaces and some of the best practices and infrastructure I introduced/built are still in place. You really know nothing about me to arrive at this conclusion, thereby proving my point that the culture has shifted - not me.
Not really, look at the schedule for 34c3. Much more interesting things and less politics.
And it also has felt more and more forced in the last couple years
Not sure the number is up from last year (I think there are fewer O/T talks this year even) but there are many talks that have nothing to do with hacking even if some of them might pigue my interest, such as the following:
Then there are topics merely having "computer" in them like everything in this day and age but aren't about hacking, and it's disappointing because I know for a fact other talks had to make room for these:
Okay, that's it. i think i will do some data analysis and do a talk at some place next year about the outcome of the analysis which talks are there and if there's really a trend. :D
I'm currently on a plane towards Hamburg and will be speaking on Day 2.

Are there any talks whose speakers are known for their expertise that one should pay attention to?

LOL, never change CCC, never change...

There was no point in time where ccc or c3 was not an political event/organisation.

Nice to see something as simple as this is enough to filter bigots away!

Holy strawman
There never a time where German hacker clubs, which are the lifeblood of this event, weren't very political - and very explicitly left wing political.
Every year the needle gets moved more
I am getting more and more confused
That's non political?
Ok let me rephrase then if you didn’t understand my point: Its getting too filled with politics that don’t have anything to do with computers

Not everything in "Hacker News" is on-topic either I guess.
The talks by e-celebs also don't bring in anything novel, like at all.
also everything is political, whether you like it or not
