    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.

    • yc-kraln a day ago ago

      Especially as congress has, for as long as I remember, been about the superset of infosec, society, art, etc. IMHO it's more along the lines of complaining about any ride that isn't a roller coaster at a theme park--no one is forcing you to go on any rides, other people clearly enjoy them, they're not taking anything away from your roller coaster, and having them increases the diversity of the crowd in an ultimately positive-for-everyone way.

      Some people just like to complain that they have to take a shower and can't harass women like they used to like they could when congress was at the BCC and that kind of nonsense didn't immediately get you thrown out like today.

        Congress has become a radical leftist politics playground. That is the real problem.

        > Some people just like to complain that they have to take a shower and can't harass women like they used to like they could when congress was at the BCC and that kind of nonsense didn't immediately get you thrown out like today.

        You could never do that. A few years ago, some activists tried to make a fuzz with stuff like creeper cards, intervention teams and codes of conduct. But those were never needed in the first place, almost nothing ever happened at CCC that would have warranted those things. But "those white male hackers are certainly sexist raping pigs" is a firmly entrenched stereotype in certain circles.

        The one thing you cannot ever do is go to CCC and express any idea that isn't very far left. That is a very certain way to get thrown out. Your talk won't ever be on the Fahrplan if the topic isn't "hooray, more refugees", "hooray, more EU dictatorship" or "hooray, down with everything right of Rosa Luxemburg".

          There is a talk on Chat Control though?..

          I don't know which past Chaos Communication Congresses you have attended, but it always was. If that's not for you, then that's too bad.

          > The one thing you cannot ever do is go to CCC and express any idea that isn't very far left. That is a very certain way to get thrown out.

          Opinions that people get thrown out for are not "I love my country" or "hey, maybe immigration should be handled differently". They're things like "Hitler was ok, actually". And IMO if a conference doesn't throw you out for _that_, it's not one worth attending.

          Which is fucking based. Being a radical leftist should be normalized even more and people like you need to be driven out of _every_ fucking public space.

        • saubeidl a day ago ago

          The problem has been the continuous purposeful rightward shift of the overton window as part of a wider strategy by the far right.

          You see it in action here, where the politics of the CCC, despite not having changed since their founding are suddenly decried as "very far left". You see the far-right decrying our democratically elected government as "dictatorship", a classic Putinist propaganda move.

          Don't let the right wing extremists set the narrative! Don't listen to their complaints about things being too "political" or "far left". It's all just a tactic in their march towards fascism.

          • toxik a day ago ago

            You could use exactly the same rhetoric to make the opposite argument.

            • saubeidl a day ago ago

              Sure, but you would be denying reality. Look at the political reality in Europe and the US.

              How many countries are led by the far right? What about the far left?

              • jasonvorhe 20 hours ago ago

                Just because you don't see the "far left" doesn't mean it isn't there. Would you consider CDU in Germany to be conservative or even Christian right now? I've been far left all my life until I noticed how fake it all is. Sane goes for the right. now I'm just following truth. It's a lonely path.

                All the best & I hope you had a Merry Christmas as well.

                • immibis 6 hours ago ago

                  CDU is not far left. It's reducing immigration, reducing social services, and removing bike lanes to make more room for cars. Not things the left is known for - but they are things the right is known for.

                  The best thing the right has done to advance its cause is to convince so many people that the words "right" and "left" don't have actual meanings.

                > How many countries are led by the far right? What about the far left?

                Since you asked the question, I assume you have an answer, and I'm curious to hear it. I imagine it will reveal more about your personal politics than any observable political reality.

              • brendoelfrendo 15 hours ago ago

                Double-replying to apologize for my previous comment! I saw what I felt was a leading question and answered it with a leading question in kind, but I got turned around reading the thread and realized much later that I actually agree with you and my answer would to your question would probably be more similar to yours than to the person you were replying to.

          • wincy a day ago ago

            If San Francisco is what you get when you embrace the left, and opposition to that is fascism, I think a lot of us have just decided we must be fascists.

            • kstrauser a day ago ago

              Never been here, huh?

            • tormeh a day ago ago

              You mean the epitome, the nerve center, the capital and apex of 21st century entrepreneurial capitalism? That left-wing bastion? Ridiculous.

            • saubeidl a day ago ago

              San Francisco is a right-wing, pro-capitalist place.

              The left would be public ownership of the means of production.

              • igneo676 an hour ago ago

                Nah, this is just the No True Scotsman fallacy. San Francisco is FAR more left in their politics than most of the nation. For example, the new mayor described himself as:

                > As a lifelong Democrat and San Franciscan, I am running for mayor to turn around the city I love

                London Breed, the mayor before, was endorsed by explicitly Democrat or nonpartisan individuals (including Kamala Harris)

                We could go on. What's ironic here is that this comment just reveals how disconnected this form of left wing politics is from the larger nation. They call even examples of the politics of their own "right wing" because they're so radically left

          • holowoodman a day ago ago

            > You see it in action here, where the politics of the CCC, despite not having changed since their founding are suddenly decried as "very far left".

            No, things have changed in CCC as well. Back in the day, free speech (in the US definition) and a firm opposition to any censorship were consensus on CCC. Nowadays, censorship is totally OK if it targets the right. And any kind of remotely right-wing opinion is declared "not free speech, not an opinion, thus not protected". This is also evidenced by quite a few talks on the topic, and cooperation with far-left activist groups like "Zentrum fuer politische Schönheit" sabotaging right-wing speech on several occasions.

            • pantalaimon 10 minutes ago ago

              Well Joscha Bach's talk got removed this year because of that mail exchange with Epstein. But disregarding the content discussed, I found it indeed a bit off-putting how he basically licked the butthole of his sponsor between those lines.

            • saubeidl a day ago ago

              Why is what right wingers do speech that should be protected, but not what the "Zentrum fuer politische Schönheit" does?

              There's a certain hypocrisy in all right wing demands for free speech. They always mean freedom of their speech, not of people they disagree with.

              • holowoodman a day ago ago

                There is quite a difference between "speech" and what ZfpS does. Their actions are often criminal, and not in the sense of "political crimes" but actually criminal acts that have nothing to do with speech or opinions. They have doxed people and called for violence against them, they have exhumed dead children and paraded around their corpses, stolen things, stuff like that.

                • ranger_danger 16 hours ago ago

                  The trouble comes when "speech" is arbitrarily defined and/or enforced to suit a narrative. The initial targets are always the lesser-favored extreme cases in order to have the least amount of people disagree with it. Then when the people are comfortable having them define what speech is acceptable, they slowly start eroding rights to include simply anything that they don't like.

                  That's why people say that taking away the rights of one group is like taking it away for everyone.

                  Do you think KiwiFarms deserved to be banned from Cloudflare and all its other former service providers?

                    > Do you think KiwiFarms deserved to be banned from Cloudflare and all its other former service providers?

                    I do believe that providers of such services such as cloud, internet, ... have to stay neutral on such purposes under nearly all circumstances. If the team behind KiwiFarms did something illegal, this is a problem for the judicial system.

                  • ranger_danger 15 hours ago ago

                    When CF continues to host 8chan and other groups that routinely trade monkey torture/zoosadism videos, but for some reason only KF goes too far... yea that doesn't make sense to me. I don't think they should be playing Internet police, and it's possible that (in the US at least) even doing so in the first place could nullify their Section 230 safe harbor protections, by attempting to moderate content that flows through them.

                    But also in KF's case I think it was not so much their content that got them "in trouble", but the people behind that crusade being so loud about it, like Liz Fong-Jones and Keffals, who relentlessly harassed every possible service provider even remotely related to any aspect of KF-related services at all, which included domain registrars, DDoS protection services, hosting/colo/DNS providers, IP space owners, upstream ISPs (and even Tier 1s), etc.

                    It was basically a master class in mentally-questionable retribution crusades for bringing their very ugly skeletons out of the closet and exposing all of their wrongdoings. LFJ was mad that their rape allegation was made public by KF, and Keffals was mad that their illegal bathtub-HRT scheme was made public.

              • ranger_danger 16 hours ago ago

                Conservatism consists of exactly one proposition, to wit: There must be in-groups whom the law protects but does not bind, alongside out-groups whom the law binds but does not protect.

            • immibis a day ago ago

              do you think the old-school CCC would be happy with a guy walking onto the stage and yelling the N word over and over, or would they kick him out? Because that's the quality of "speech" they now support "censoring".

              • holowoodman a day ago ago

                Being (un)happy about something is totally different from creating and promoting an oppressive censorship apparatus, criminal laws and police actions against that something.

                Imho: You don't have to like that person yelling that stuff. You don't have to like what they are yelling. But you have to accept that it has to be their legal right to yell that stuff. Because otherwise, any opinion will one day be a criminal thing to say, just takes one election...

                • immibis 21 hours ago ago

                  You actually don't have the legal right to walk on stage at C3 and yell the N word repeatedly. The fact you think you have or should have that right means I am not the extremist in this conversation.

    • moltopoco a day ago 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.

      • VierScar a day ago ago

        The first two talks are in the "Ethics, Society & Politics" category, and the third in the "Art & Beauty" category. Why would they need to be about computing?

        It's a big organisation, and politics is wrapped up in what they do, along with the post-WWII Antifaschism culture in Germany.

        Even if it weren't the case, I don't get why attack them for helping stand up for democracy, something in dire need of advocacy these days

      • rapnie a day ago ago

        Unrelated to this conference I've often heard the "everything is political" argument, and mostly with a passive-aggressive "or else.." (you're up for a political fight) undertone. I once enquired on very mundane things in life, and yes "those too are political act". Well, if everything is bleakly political in that sense, we may make it universal, just call it Newspeak.

        • immibis a day ago ago

          Definition of politics: whenever two agents have conflicting goals and a resolution is reached (peacefully or otherwise). Or more succinctly, multi-agent dynamics. Yes, almost everything is politics, and this is not diluting the word, any more than saying that almost everything is made of atoms is diluting the meaning of the word "atoms".

          (Parent comment was edited to remove the part about diluting meaning)

    • randomNumber7 a day ago ago

      Maybe it's that people disagree with the politics, but also don't see a room for discussion.

      • immibis a day ago ago

        In my experience, you are right - that is what most complaints of "too political" really mean.

    • aleph_minus_one a day ago 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 a day ago 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.

    • Fnoord a day ago ago

      Having any hacker conference in the USA is a political choice, because it deters any non-US citizen from entry. The bars to enter the USA are high, including the coercion to hand over your accounts from social media.

      • jna_sh a day ago ago

        I’m not sure you think otherwise, and are just calling on the US as an example since the HN crowd is heavily US skewed, but just for the avoidance of doubt, this is a German event.

      • GuB-42 a day ago ago

        The US is a large, well connected country with a lot of hackers, for all definitions of "hacker", it is even the country that created the term.

        And it is not that inaccessible to non-US citizens. Sure, the current administration is not very welcoming, but it is easier than, say, Russia (where a lot of hackers also live) if you want to attract an international audience.

        Anyways, it is the CCC, and they are doing it in Germany, of course, because they are German.

        • aleph_minus_one a day ago ago

          > And it is not that inaccessible to non-US citizens. Sure, the current administration is not very welcoming, but it is easier than, say, Russia (where a lot of hackers also live) if you want to attract an international audience.

          I would say that with the current US administration, it is similar hard to get to the USA as to Russia.

          The difference rather is that in Europe's hacker scene there exist quite some people who, if they stated their opinions openly, would get in much worse trouble if they stated their opinion in Russia than in the USA (because in the USA these opinions are currently "more acceptable"). On the other hand, for Russian hackers likely the reverse holds: I can easily imagine that quite a lot of Russian hackers, if they stated their opinions in the USA, would attract quite a lot of trouble.

          Just to be clear: I consider it to be quite plausible that in 5 years, the situation might be similarly bad in the USA as it is today in Russia.

        • Fnoord 21 hours ago ago

          Now, I could say a lot of things Russia is known for, but not for their rich hacker culture, lest it to be mentioned in the same context as USA. Russia simply isn't known for their large hacker culture; Europe is (since I want to include a member of FVEY, specifically a country which Brexited, and am also referring to a time when EU did not yet exist). A somewhat dark past of CCC is related to Russia via Eastern Germany by CCC member Hagbard (my nickname here related to it). Back in those days, the hacker culture very much was counterculture. KMFDM has a couple of good tracks about it.

          CCC is German, and started in West-Germany. It is the oldest hacker conference. The second was USA (DEF CON), and the third was The Netherlands (theirs is approx every four years, and has a different name every year). The first one in NL was HeU 1993 (Hacking at the End of the Universe). This list excludes demoscene (IMO part of hacker culture due to reversing / cracking software, plus programmming and art in limited constraints, but at the very least it is related to); the first demoscene party was called Copy Party in Finland, 1980. Nordic countries are well represented in demoscene.

          I am only aware of one person who fled USA to RU, and said person wasn't known in hacker culture before he did, plus he ended up there by mistake. By contrast, various people in infosec left USA for Europe. Jacob Applebaum went to Germany, Drew DeVault went to The Netherlands.

          Since 2022, brain drain started in Russia due to the full scale invasion and war with Ukraine.

          There's a very free country near the USA which does not have the ridiculous entry requirements the USA has. It even has a couple of large cities near the US border, including near cities with a rich hacker culture. Entry to said country is about as easy as entry to Germany. The country is called Canada. Yes, your neighbor.

          May HOPE, DEF CON, and Black Hat end up in a tolerant, hacker-friendly country. I am not aware of brain drain due to Trump II. I mean, it is happening, but it also happened during Bush era, and the proportions I don't know about.

          As for CCC being held in Germany. They have been very open to foreigners (as have us Dutch been), famous USA hackers were always welcome (and came) to hacker conferences in NL and DE. Talks in NL were almost all in English, at CCC partly (German is a relatively popular language in Europe). Nowadays, almost all German talks get dubbed and subbed. So CCC is very American-friendly, cause we Europeans get that Americans speak almost exclusively English only.

    • GuB-42 a day ago ago

      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.

      • Fnoord a day ago ago

        Politics is a game too. With far less fun rules, unfortunately.

    • Sol- a day ago ago

      The shape of the politics changed, though. From civil rights, questioning authority and cypherpunk, which inherently has a libertarian bent, there's now much more identity politics and social justice / grievance culture with only tenuous connections to tech.

      For a hacker conference, they also are pretty Luddite against new technologies like AI. It's a very conservative degrowth movement nowadays, all in all.

      • aleph_minus_one a day ago ago

        > For a hacker conference, they also are pretty Luddite against new technologies like AI.

        Hacking was always against centralization and central control (and towards decentralization) - which is why any lecture celebrating the bigtech AI companies would strongly be against the whole culture.

        While for various reasons AI is a controversial topic, I would say that if someone gave a great talk about how to decentrally train some AI model efficiently as some volunteer computing project, this would be perfectly fitting for the C3.

        Addendum: There is an AI talk (as pointed out by wunderwuzzi23 at https://news.ycombinator.com/item?id=46390959): https://events.ccc.de/congress/2025/hub/event/detail/agentic...

      • eqvinox 18 hours ago ago

        > For a hacker conference, they also are pretty Luddite against new technologies like AI.

        No, just this one, because it steals from almost everyone and gives to the few. Even if it seems to be somewhat failing at monetization for now, control is in the hands of a very few.

      • flawn a day ago ago

        I am happy they are careful with new technologies, especially one like AI, and also set the right impulses. Enough non-political reasons to have that stance, especially taking in societal implications and how technology affects everyone and not just stakeholders and techbros. In a time when tech in the US is just accelerating by the top-down agenda of figures like Andreesen, Thiel & Co., that is very much needed imo.

    • BoingBoomTschak a day ago ago

      The vagueness and sheer breadth of the word "politics" is doing the heavy lifting in your argument there.

  • Foxboron 2 days ago ago

    https://streaming.media.ccc.de/39c3

    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 a day ago 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 a day ago 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.

      Really enjoyed your talk two years ago :)

  • shmeeed 2 days ago ago

    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!

    • basilikum 2 days ago 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.

    • bwblabs a day ago 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 a day ago 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).

    • dim13 a day ago ago

      It is no longer the same. It went from somewhat exclusive dining experience to full blown nuclear junk food chain vibe.

      I've stopped attending it about 10 years ago. I rather prefer to watch some few interesting topics online, and skip all the wanna-be political junk.

      • immibis a day ago ago

        You choose to ignore politics, but politics doesn't choose to ignore you. Ostriching doesn't seem productive.

          But listening to pep talks of political opinions that are very opposite to yours does not seem productive, either.

      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.

    • Den_VR 2 days ago 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 2 days ago 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.

    Going to CCC changed my life last year and really opened up my eyes. So sad I'm not able to attend this year, but hoping I am able to return soon. Anyone who understands why technology cannot be viewed in a vacuum without considering the humans who use it will fit in immediately. Do yourself a favor and go.

    • Tepix a day ago ago

      If you can't make it to Congress go to one of the hacker camps in the summer.

        I was at WHY and it was even better!

  • ekjhgkejhgk a day ago ago

    Uncertain if this is OT, but given that the CCC is politically inspired organization, I hope not:

    One thing that still seems absent is awareness of the complete takeover of "gadgets" in schools. Schools these days, as early as primary school, shove screens in front of children. They're expected to look at them, and "use" them for various activities, including practicing handwriting. I wish I was joking [1].

    I see two problems with this.

    First is that these devices are engineered to be addictive by way of constant notifications/distractions, and learning is something that requires long sustained focus. There's a lot of data showing that under certain common circumstances, you do worse learning from a screen than from paper.

    Second is implicitly it trains children to expect that anything has to be done through a screen connected to a closed point-and-click platform. (Uninformed) people will say "people who work with computers make money, so I want my child to have an ipad". But interacting with a closed platform like an ipad is removing the possibilities and putting the interaction "on rails". You don't learn to think, explore and learn from mistakes, instead you learn to use the app that's put in front of you. This in turn reinforces the "computer says no" [2] approach to understanding the world.

    I think this is a matter of civil rights and freedom, but sadly I don't often see "civil rights" organizations talk about this. I think I heard Stallman say something along these lines once, but other than that I don't see campaigns anywhere.

      The C3's attendees are quite knowledgable in computing topics, so there is no need to bring coals to Newcastle.

      The CCC is a German organization. In Germany, the general public already is quite skepctical of tablets in classrooms, so there is not such a necessity to inform the general public of something many people already think.

      While there exist initiatives to use tablets in school in Germany (see for example [1]), these (in my opinion misguided) initiatives rather typically fail for financial reasons and because most teachers simply are incapable of using the technology. And, of course, tablets fail all the time.

      So, in other countries this may be an important problem, but in Germany, any initiative for tablets in school already fails by the mere incompetence and the mills of bureacracy, so this is rather a potential topic for hacker conventions in other countries.

    Some talks which sound really brilliant. I love [0] exploiting a memory leak for years before it's fixed. Also [1] I'm really curious about the custom crypto used in Chinese apps. Oh and curious about the found [2] GPG vulnerabilities. I think some of the politics ones are actually also very interesting. Looking forward to the streams.

      The first one is indeed fascinating...almost deserving of its HN post :-)

      It has been submitted six times in the last 10 months, with a grand total of 1 comment...I though this site had Hacker in the title...

      https://hn.algolia.com/?q=https%3A%2F%2Fgfw.report%2Fpublica...

      • immibis a day ago ago

        Common misconception. HN uses "hacker" as in "the people who do the work that makes Y Combinator rich" rather than "someone who plays with technology". HN hackers are contrasted with CEOs and so on - people whose job is not the on-the-ground work.

  • abdullahkhalids 2 days ago ago

    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 2 days ago 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 2 days ago 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 2 days ago 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...

    Lefties sympathizing with criminals, sharing their wealth distribution fantasies, agitating against competing political views. You've come a long way, CCC! The initial ideas was political, but with a clear focus on freedom of information, and the power to govern your own personal data.

        • lhoff 2 days ago ago

          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.

        • derrida 2 days ago ago

          > but it starts at 4 AM for me.

          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)

        • yk 2 days ago ago

          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.)

    From year to year more politics and less interesting stuff.

    • flohofwoe a day ago 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 a day ago 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 a day ago 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 a day ago 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 a day ago 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.

              • holowoodman a day ago ago

                Back in the old days, you could sit down at a table in the hackcenter and do stuff that was more of the exploratory pentesting kind. Because everyone around you understood. Because there were strict "no-photos" policies in place. Because all people were technical and in it primarily for the technical challenge.

                Nowadays you cannot do that anymore, because most visitors are non-technical. Nobody respects the photo policy. Everyone judges your actions through their political lens. Instead all the "action" happens elsewhere and CCC became much more about social stuff, talking and politics. And of course about policing and judging other peoples' politics.

              • monerozcash a day ago ago

                I'm not just referring to the talks, but the whole event. But we used to have groups like wikileaks heavily featured, they certainly weren't worried about too many eyeballs.

                • immibis 7 hours ago ago

                  Actually I can't ask a court whether you were at that conference without knowing your legal identity - care to share? And why should I expect the court to have a complete list of who was there, and to answer questions about that list? Seems much easier to ask you, and it's strange you don't want to answer.

                  • sunaookami 3 hours ago ago

                    What are you talking about? Pure nonsense. Discussions about "great replacement" never happened, that's an undeniable fact proven by court records and news media are not allowed to repeat these claims (324 O 439/24, 324 O 524/24, 7 W 78/24).

          • jasonvorhe a day ago 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 a day ago 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.

    • littlecranky67 a day ago ago

      CCC was always political (very left to far left). Never understood why hacking has to be political in the first place.

      • jonesjohnson a day ago 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

        • panick21_ a day ago ago

          That chernobyl and western politics is in any way connected is due to decades unscientific fearmongering. And Berlin has always been a hotbed for that.
