    I'll never get people who say that there is too much politics at a god damn hacker conference like the CCC, considering The Chaos Computer Club was founded in 1981 specifically to be a political watchdog.

    more so especially since the very act of "hacking" is a political statement because it involves redistributing power over information.

    Code is law, remember?

    That would be like complaining about "too much law" at a constitutional convention.

    • moltopoco 30 minutes ago
      It seems that no modern comment section is complete without the complaint "too much politics", then followed by "but everything is political". Some talks do not even try to draw a line from politics to computers, and I think that is what people feel unhappy about.

      For many hackers, it is just a game, a technical puzzle. The interesting part is overcoming the obstacles, the information or bounty money they get in the end is just the reward, its nature doesn't matter much. Even when there is no reward, people do it because it is fun.

      Like with lockpicking, many pickers work with the cylinder in a vise, and the lock is just a mechanical puzzle. That the lock can be attached to something one would want to secure is just a distant thought.

      Maybe it's that people disagree with the politics, but also don't see a room for discussion.
    • aleph_minus_one 42 minutes ago
      I get your arguments. In my opinion the core of the problem is that a lot of the "political" taks are about political topics that are outside the core of the kind of politics (?) that are related to hacking. These talks are what people are complaining about as "too much politics".
      • user764743 26 minutes ago
        That's fine but technology doesn't exist in a vacuum, you can't talk about (for example) facial recognition technology without mentioning the social groups it affects the most or is used against. Same for plenty of others topics directly or indirectly related to hacking and computers.

        If you look at the history of the CCC, they also don't see a line between technical freedom and social freedom, because you can't have a free internet in an unfree society.

        The 'outside' topics you mention are often just the hackers' way of applying their methodology to the world beyond the screen. Society is a larger system with its own bugs and exploits that inevitably affect the computers you use and the code that run them, and hackers like to apply their methodology to analyze that to understand the consequences.

        Moreover, if you actually want meritocracy, you have to address the social barriers that keep people out of the room, and you can't do that without addressing the outside world.

    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

    The final recording will appear under a day or two after the talk is held: https://media.ccc.de/c/39c3

    EDIT: A different variant of the schedule with better filtering is available here: https://events.ccc.de/congress/2025/hub/en/schedule

    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.

    • _jomo 2 hours ago
      I made https://fahrplan.cc where you can filter the [not] recorded sessions, categories, and titles.

      I've mostly made it for myself to skip the recorded sessions when on-site and to see what's coming up at the current time of day. It therefore tries to include all the self organized sessions, workshops, meetups, music programs, etc. I've been running it for a few years and people use it for all kinds of use cases, including sitting at home and watching the streams.

    • elcapitan 5 hours ago
      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!

    • bwblabs 5 hours ago
      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).

      • bwblabs 2 hours ago
        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).
    • basilikum 11 hours ago
      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.

    • Den_VR 6 hours ago
      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.
    • embedding-shape 11 hours ago
      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 see a lot of great talks whose topic is worth attending.

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

    • embedding-shape 11 hours ago
      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.

    • seanieb 12 hours ago
      Two big names that jump out, the CEO of Signal Meredith Whittaker and Cory Doctorow. They both frequently give thought provoking talks.
    • g-mork 10 hours ago
      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.

      All of these looked good to me this year: https://halfnarp.events.ccc.de/#e72b9560a7c729d1b38c93ef18a5...

    From year to year more politics and less interesting stuff.
    • flohofwoe 3 hours ago
      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.
      • monerozcash 2 hours ago
        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.

        • meibo 2 hours ago
          There has been plenty of direct action in recent years, but I can't really think of any on a global scale. Lots of smaller things on a German level, like journalists reporting about infiltrating a Great Replacement conference hosted by the second biggest political party here.
          • monerozcash 1 hour ago
            Sure, but it is unarguably much more boring stuff than it was years ago. I attend almost every Congress with a variety of groups, and there's certainly been a culture shift over the years from lots of anarchists who had no qualms with breaking the law to much more corporate scaredy-cats.

            Congress seems to keep growing so perhaps this is just serving a broader audience. But knowing a lot of long-time attendees, I'm certainly not alone in thinking Congress is starting to be less interesting than it used to be. I'm certainly not trying to say the event sucks though, there's still a plenty of interesting stuff happening.

            • pinkgolem 44 minutes ago
              Love that you complain about not enough people breaking the law and somewhere below complains about to many people breaking the law

              Let's be real, the videos get far to much eyes to break the law. There are smaller talks and groups where it looks different.

    • deknos 4 hours ago
      again this myth. look at past fahrplans, there was always quite some political stuff. you just agreed with it and therefore it was not inconvenient.

        • DHolzer 3 hours ago
          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.
          • jasonvorhe 3 hours ago
            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.
            • nosianu 3 hours ago
              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.

      CCC was always political (very left to far left). Never understood why hacking has to be political in the first place.
      • jonesjohnson 39 minutes ago
        well, it has a lot to do with people growing up during cold war and german reunification.

        There were many stories where people lost faith in politics (e.g. after Chernobyl), so people gathered together to do stuff on their own. I think being "social" (to all people), decentralized and mistrusting authorities is just a left thing. so that's just a natural thing imho

    • blueflow 2 hours ago
      People come for the technical talks and leave for for the politics.

      Every year you got new people who find out the hard way that the CCC is a place for ardent activism, not for critical thinking.

      The people who stay do it to meet their friends there.

          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.

          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.)

    • pinkgolem 5 hours ago
      I see this comment every year, and I am confused every time.

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

      • frankzander 5 hours ago
        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.
        • jasonvorhe 4 hours ago
          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.

          • frankzander 3 hours ago
            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.
          • meibo 3 hours ago
            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.

            • jasonvorhe 3 hours ago
              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.
            • mdavid626 3 hours ago
              Culture changes, that’s true. However, “change” doesn’t normalize the far left/green initiatives.
              • meibo 3 hours ago
                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 :)

            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.

              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.

            • jasonvorhe 3 hours ago
              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.

            • frankzander 3 hours ago

        • izacus 4 hours ago
          I've been there like 2 decades ago and even then it was a deeply political event.

          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.

          • charcircuit 4 hours ago
            Even if it was equally or less political than before, it could still be too political for someone that would be worth including.
          • moltopoco 1 hour ago
            We might be the same age; I remember that defacing conservative websites was already a C3 thing about 20 years ago. Back then, it felt good to punch up against authoritarianism. Hackers hated Bush and his Patriot Act just as much as many hate Trump now. In Germany, the CDU is of course the perennial enemy.

            But what happens when authoritarianism does not come from the right, but from the left or center? (Not a contradiction: East Germany was an "anti-fascist" totalitarian state as recently as 40 years ago.) Sadly, I think we have been slowly moving in this direction since Covid, where I was genuinely shocked that many of my "leftie" friends had turned into government drones (from my perspective), while they were deeply disappointed that I was now a "right-winger" (from their perspective).

            The more aware they become of how unpopular some of their politics are, the less they believe in democracy as a concept, while I'm still jealous of countries that have proper referendums and freedom of speech. Hate Speech laws are accelerating this divide.

            Anyway, I think that these are the dynamics that are driving many people apart who all simultaneously claim to not have changed in decades. The CCC is still doing a lot of great work, but I do feel it drifting away from me because it is not so much about punching up than about punching right.

      Personally, I’m very much looking forward to the many talks from the „politics“ category. You have the wrong mindset.

      Originally, I wanted to enjoy the cringe fest of privacy related grandstanding while the „community“ was absolutely silent during the dystopian Covid overreach.

      But then I spotted, between the many „Nazis everywhere“ vibed talks, one spectacular Antifa affiliated talk about the „Budapest-Complex“.

      > Der Vorwurf der … steht in keinem Verhältnis zu den verhandelten Vorkommnissen

      Roughly translated: The claim of … is completely disproportionate relative to the discussed events.

      „Discussed events“ as in? That some random pedestrian almost got killed because someone decided he‘s a neonazi? Hammers are nowhere to be mentioned. I mean, my knowledge of this is a little bit rusty, but somehow I get the feeling it’s going to be an inspiring leadership class in bending the meanings of words.

      By the way, the Antifa-Ost which this talks seem to be concerned with is afaik exactly one of those groups mentioned in the recent US admin‘s update to the list of terrorist groups.

      Highly recommend this talk!

      you mean too much politics you disagree with

      also everything is political, whether you like it or not

              that's because you have a very narrow definition of what political means
