Call for Subtitles

Fri, 03 Jan 2020 20:27:37 +0000

Have you been hit by Post-Congress depression? Are you sitting at home and watching recorded Talks from between the years?
Bring a little bit of Congress to your home and help with improving quality and accessibility of the CCC recordings! You can work on the subtitles from the comfort of your home, as long or as short as you like to!

How does this work?
The transcripts are generated automatically by speech recognition software and improved and corrected by you. Since talks contain lots of domain-specific terms and may have speakers with heavy accents, this is very much necessary. The next step is again automated: aligning the subtitles to the audio. Again, the result of this process is verified by you. Afterwards, the subtitles are finished!

For a more in-depth description and how-tos, take a look at c3subtitles Wiki.

If you have any questions, contact us via any of the channels below!

You need subtitles? Let us know which talks you are interested in!

Recreate Minds and Bodies and Keep Enjoying! #36C3 #ABFahrplan

Fri, 27 Dec 2019 20:53:07 +0000

Resources are limited and we are exhausted.

Here is no blog post, but the ABFahrplan.
Go, listen, chill, admire, dance.
Let’s recreate minds and bodies and still keep enjoying.

Call for interpreters: Translate 36C3!

Thu, 26 Dec 2019 11:00:12 +0000

Heading for Congress, unsure what to do there, interested in applying your impressive language skills? If you are multilingual and fluent in German, English and maybe other languages, please consider joining the translation team.

We interpret ALL talks in the five main halls live and in real-time. German talks are interpreted into English, and vice versa. Our work is transmitted live in the lecture halls, streamed to the Internet, and recordings are published on CCC sites and YouTube. A second translation channel will be operated in the same way.

That is a lot of material to translate and in order to succeed, we need YOU. With the second channel, you have the chance to contribute in an even more special way if you can interpret into another interesting language (from English or German). We’ve so far focused on adding French language translations, but if your skills differ just let us know – especially if you can bring along a few interpreters for the same target language. Sometimes, we might even use the second channel for interesting things that are not (strictly) translations.

Don’t be shy. If you are uncertain whether you’re good enough, chances are that you’ll do just fine. In case you‘re struggling, we will talk it over, no harm done.

Simply send an email to “translate-subscribe(at)lists.ccc.de” and write a quick intro to the mailing list after you’ve completed your subscription. Also sign up as a translation angel at the Engelsystem. Most importantly, come to one of our meetings. The kick-off meeting on 26 Dec, 20:00 would be best, but if you can’t make that, join us at the earliest meeting that you can attend.

So please, take this chance and help us bring C3 to an even wider international audience.

For more information, you can contact us on Twitter at @c3lingo and #c3t, or via mail to translate(at)lists.ccc.de (after subscribing).

See (and possibly hear) you at 36C3!

36c3 Assembly Anreise

Wed, 25 Dec 2019 20:49:26 +0000

Dear Assemblies,

please be aware that you need to have your congress-wristband to enter the premises starting from 27.12. Furthermore we need the number plates of the cars with which you intend to deliver stuff. Please send them as a mail to 36c3@c3loc.de or call us at 0341-39294864, the gate will only let declared cars pass.

Entry to the premises has to happen via Gate Süd 1, from there you’re able to drive directly to the halls. You can look up which hall your assembly is placed in using c3nav. Please use the logistics area in front of Hall 2 – Gate 2.5, Hall 2 – Gate 2.6 and Hall 3 – Gate 3.6 to unload. There you will find Angels with pallet trucks which can help you transporting your stuff to your assigned space. Please occupy them as little as possible, a good many assemblies will arrive in short order.

Additionally do keep in mind that your vehicle must at most spend 45 minutes on premise, afterwards the Messe will charge you fees.

One last thing: you can find information about trash and broken glass on the Event Wiki Trash page.

Choose any topic you care about – your favorite programming language, a hobby you’ve started hacking, or a discussion group to find friends with similar interests – expand the topics and the program of 36C3!

Please head on to the Wiki and enter your session to contribute your bit to a diverse and versatile Chaos Communication Congress!

Meet the 36C3 track team “Resilience and Sustainability”

Tue, 03 Dec 2019 23:23:36 +0000

We’re 36C3’s Resilience and Sustainability content team and want to show you just our bit of work that helped making this year’s Fahrplan as amazing as it has turned out.

Our team consists of hackers and scientists, tinkerers and PhDs and was formed for 34C3 when we felt that the conference was developing a blind spot between complete destruction of all the IT things and the fascinations for the resulting apocalypse. We wanted to give a stage to new and shiny useful technology for a better and more resilient world – with actual prototypes!

This year’s motto “resource exhaustion” added a perspective on sustainability to the track – even though the term is rather overloaded. There’s a plethora of conferences selling you on the most recent hypes about how machine learning, crypto currencies and the cloud will save the world, but we think that it is in the spirit of this community to question everything, think and focus on technology that will last for much longer – both physically and from a software engineering point of view. We found it fitting to see how the existing resources can be used and reused, who’s building resilient technologies that can help people in emergencies, oppressive regimes or off-grid situations, and – in a broader scope – how can we build the systems of the future not riddled by the problems of our generation.

Along the way, we hope we can make software developers think about the impact of their busy-looping JS, bad communication patterns and faulty software architecture – all of which are significantly contributing to climate change.

The concept of resilience itself – especially combined with sustainability – is rather interdisciplinary, part hacking and making, part science and politics. This puts us in competition with other track teams trying to catch the most interesting lectures for a given subject, but also allowed us to trade slots with those teams as well, once we were running out of our allotted time budget. ;)

Next year, we hope to collect the “haveyoursay” feedback much earlier so we can incorporate your feedback and follow your suggestions for valuable speakers and topics.

While we were quite pleased with the submissions we found once CfP kicked off, our curation process started way earlier: Reflecting on feedback we received after 35C3, we came together in IRC and RL, brainstormed about interesting projects we heard about in the past year, thought about relevant topics and identified speakers worth having.

Even then, the speakers we “invited” still had to go through our rigorous curation process. After all, our team received a total of 74 lecture submissions and had to narrow them down into only 15 hours (in 18 lectures) of 36C3 programme. We vetted each submitter, trying to make sense of their submission, read their papers, ask and answer questions and spend the remaining time meeting and coordinating with all the other track teams, before finally writing this blog post! If we add up all the time spent preparing our 18 lecture foot steps in the Fahrplan, we’re looking at one or two weeks full time work for each of us.

In the end we’re quite proud of the topics we could cover this year. Of course, we’re still not short of topics to cover next year :-) It’s time for more critical reflection of wastefulness within the computer nerd scene and how we can minimise the environmental impact of our C3s and Camps in the years to come.

36C3 Phone registration is open

Sun, 01 Dec 2019 22:42:54 +0000

We are pleased to inform you that even with Resource Exhaustion the registration of telephone extensions for the 36th Chaos Communication Congress is open. Don’t get confused by the social media, it works without any voucher :-). You can claim your DECT, SIP or GSM extension in the Generic User Registration Utility (GURU). Like last year, you can register your devices on site yourself. Don’t forget your devices and chargers, chasing records, this year we want to break last year’s 6488 extensions.

Stay connected!

Call for Angels for the 36C3 buildup and teardown

Sat, 23 Nov 2019 07:15:41 +0000

TL;DR

The buildup and teardown of 36C3 needs angels!

If you want to help with the buildup, you can come to Messe Leipzig from the 18th of December and show up in Heaven (CCL) or in hall 4 for info.
Bring warm clothes and solid shoes. Safety shoes, if you have some.
Be careful – buildup means the halls are construction sites! Take care of yourself and others. Stay in safe distance from vehicles and heavy machines and leave your pets at home. Please don’t bring children before the official start of the event if possible.
If you can stay a couple of days longer and want to earn eternal angel karma please help with the teardown! Teardown starts after the closing ceremony and goes on until the 5th of January, which means we have less than half the buildup time. So we need every possibly available angel. We will post more info regarding teardown on this blog soon.

For further info check the Event Blog for publications.
For concrete questions: 36c3@c3loc.de

Long Version

Like every year we need as many angels as possible for the 36C3 buildup so that the boring halls evolve to one shiny colourful Chaos Communication Congress.
This year’s buildup starts on the 16th of December. During the first two days there will be mostly just team arrival and bootstrapping before it all really takes off. After this more parallelized tasks will show up every day. The majority of tasks take some time to surface. Because of that we ask especially the non-Leipzig-locals to rest some days instead of arriving early and come to the buildup from the 18th of December. Don’t worry, there will be more than enough to do and more with every day.

What needs to be done?
There is a huge amount of variety in the tasks that need to be done so that everyone should find themselves a topic that fits them. Some tasks have been planned before but the majority of things happens quite spontaneously because we cannot anticipate everything very well beforehand. Especially the time tables are very fluid and can change quickly at times. Because of that there is no angel system or online shift planning used during buildup. Just come over and pick a task that suits you onsite. Please ask in Heaven, which is located in the CCL, what needs to be done at the moment or get yourself some info. If Heaven is not running yet come to the Preheaven in hall 4.

What else must be observed?
The halls are not heated during buildup. Bring some warm clothes that don’t mind some dirt and bring solid shoes, bonus points for safety shoes S1 or higher. We have some personal protective equipment (PPE) to offer but if you can bring your own working gloves, tools, $(safety-)gadgets you are more than welcome to do so.
Despite the often chilled atmosphere during buildup please remember and be aware that the buildup is a construction site! Take care of yourself and the people around you and keep safe distance from heavy machines, cars, forklifts, trucks etc.
Please don’t bring children before the official start of the event if possible. Children are an immense safety risk in the construcion areas – mostly for themselves. Please also leave your pets at home. An event with 16.000 attendees isn’t the right place for animals anyway.

And the teardown?
Teardown starts on Day 4 directly after the closing ceremony and goes on until the 5th of January.
Especially during this phase we need every help we can possibly get. Everything brought into the halls during the two weeks of buildup needs to be brought out again within six days – which is less than half the amount of time. We are thankful and happy for every angel who is able to spend some more days onsite and help with tearing down this huge event.
More info especially regarding teardown will be posted on this blog soon.

See you in Leipzig!

Behind the scenes: Chaos Communication Congress presale

Mon, 18 Nov 2019 10:36:16 +0000

A scanner, watching you. Beep!

Have you ever tried to solve a problem that is completely, utterly, ridiculously impossible?

Welcome to our world! We’re the team running the Chaos Communication Congress ticket sales, and we want to follow the good example set by the content teams, and explain a bit of our work.

Now, from the outside, our problems may not seem all that impossible. In fact, you may think we have very little problems indeed: We run the presale of a conference that is notoriously sold out, and that’s generally what you want when you organise an event, right? Well, yes and no. Our primary goal is neither to sell every last ticket nor to increase our prices knowing that we’ll be sold out anyways – our goal is to invite participants in a way that is consistent with the values represented by our event and our community.

The Chaos Communication Congress is first and foremost a community event. Its unique beauty as well as its unique challenges originate in the fact that we are a huge distributed anarchical group of unpaid volunteers who manage to build an event for over 16000 people, every year. To make matters even harder, our completely self-organised decentralised structures work without a single point of authority. If you think that this cannot possibly work, you’re not alone: It’s hard to explain to people on the outside, and when we try, we’re usually met with a blank stare or disbelief.

None of our Congresses would work without two overlapping, vaguely-defined groups of people: The teams who spend inordinate amounts of time before and during the event organising and working, and the local groups and hackerspaces who do a lot of great work throughout the year that has nothing to do with Congress at all. Without the people tinkering in hackerspaces, running smaller events, creating awesome new hacks, educating people, visiting schools to talk to kids, running workshops, discussing positions and organising protests … we wouldn’t have the vibrant community that turns Congress into an event without its like.

Consequently one of our goals is to make sure that both organising teams and active people from other groups have a chance of attending Congress – but at the same time, we don’t want to limit ourselves completely to people who have already done their part. We’d be completely caught in our own filter bubble, and therefore we also want Congress to be accessible to new people.

This is a tough one. Fundamentally, there cannot be a perfect solution: We sell less tickets than people want to buy and our community grows larger every year. Period. Which means that some people will not be able to buy a ticket, no matter how much they want to, or how good a fit they’d be for the event.

Possible solutions to this are manifold: We could turn the event into a private event only for people who are already part of the community. We could just increase our ticket prices until the demand balances with the available tickets. We could go by “seniority” within the community, or by capability by introducing artificial technical barriers (a quiz? a hidden ticket sales server via ssh?). We could insist on a personal recommendation from a trusted person, or expand this into a dystopian voting system where only people with a sufficient number of votes get in. We could set certain quotas by demographics and then distribute tickets according to age, gender, social status, income, text editor, or hair color. We could make ticket sales entirely random (more on that later), or just sell as many tickets as we can, ignoring the problems that start when you let a community grow faster than it can support itself. But we don’t think any of these are a good idea.

Our current solution works like this: We don’t sell all tickets to the general public. Instead, we start by handing vouchers to all dedicated volunteers from last year’s Congress, so they can buy a ticket for this year if they want to. Simultaneously, we also give vouchers to local groups, like hackerspaces, and some activist groups. Their vouchers spawn new ones once they have been used, so that these groups can distribute the vouchers among themselves. Roughly half of our tickets are sold to somebody with a voucher. (The truth is slightly more complex, and if you like reading rule books, you can read up on them in our documentation).

Once the tickets reserved for the active community are used up, we turn to the remaining tickets, and sell those in three open presale days. They are notoriously gone within minutes, if not seconds. The technical challenges of serving several thousand requests per second in an attempt to sell tickets is interesting in its own right, but we’ll leave that ~~as an exercise for the reader~~ for another post.

Obviously, this is not an ideal system and it fails in a variety of interesting ways. For example, local groups may have questionable priorities when distributing their vouchers. People may have broken mailservers and will never receive their voucher. People who use a reproducing voucher may take a long time to pay, blocking people who wait for their replicated voucher. If you have very slow internet or slow reflexes or are not aware of the urgency, buying a ticket in the open presale is nearly impossible. It’s frankly heartbreaking to talk to people who will not be able to attend Congress.

And that’s a significant part of what we do: As the presale team, we answer all emails sent to our address, usually within a day. Last year, we received a total of 2690 emails and sent 1764 in 1623 threads, so roughly 10% of attendees contacted us. This excludes spam, but includes bounces – because we look at those, and try to figure out if there was a typo in the mail address, or if we know somebody who knows this person and can get in touch with them. If you write us, you don’t receive a canned response either – every response is more-or-less lovingly created by one of the four of us.

Other than that, what do we do? We usually deal with requests for vouchers from various groups, which has served to expand our knowledge of geography. Occasionally we help settle local conflicts when one group won’t talk to the other – it’s the Chaos *Communication* Congress, after all. To keep our workload at an unreasonable-but-possible level, we try to send vouchers to only one place per city, region, or thematic community. We also help people who found one of several tempting ways to make errors in their ordering process (typos in email addresses or payment references are the favourite). We help with payment difficulties and supply people with documentation for their visa application. We prepare the on-site ticket checkin – scanning this many tickets is a challenge of its own, of which we have written more here. We also administrate the servers, which is especially challenging when preparing for the open presale days, which can see request spikes of more than 16.000 requests per second, and requires a bit of careful planning. Before the presale starts, we negotiate conditions with the local public transport company, and help determine the ticket prices and what average ticket price we need to reach – you can always see the chart of average ticket prices here.

We’re also constantly looking for ways to improve the presale. Every year we make some minor changes and adjustments that go mostly unnoticed (which is good!). We have experimented with simulating parts of the presale, to get a feeling for the results that we would introduce with different replication rates, spawn times, and distribution mechanisms. This also involves talking to lots of people to help us balance the needs of different groups: Within Germany and from abroad, from within the community and newcomers, marginalised groups and people who have been around for most of CCC’s history, people who cannot participate in a regular presale for health reasons, and so on.

We’re nearly always happy to discuss your ideas, and we only have two requests if you want to let us know what you think: First off, please assume that we’re trying our best – because we are, and people who send us very angry mails about our malice or our incompetence just make us sad, but won’t improve the presale process.

Secondly: Please do not suggest that we try a lottery. We know, it’s tempting – it’s the first solution that springs to mind to solve this problem, but it’s also just not going to happen. The short explanation is: Any lottery that can’t be cheated easily will require us to check people’s IDs at the entrance, and that’s not something we are willing to do – both due to the logistical challenge of slowing down the entire check-in process extremely, and because we follow the principles of minimal data retention. We don’t care about your official names, we don’t want to check your ID, and we run screaming when thinking about the implications of this level of data aggregation.

A last note: While we have seen a lot of bitter, or angry, and occasionally hateful messages, we have also seen plenty of support, humour, and good-natured snark, which makes the whole effort more than worth it. Thank you!

36C3 content teams running full steam

Tue, 29 Oct 2019 16:58:41 +0000

Last Sunday at midnight the submission period for our Call for Participation ended. The last submission, by a Swiss, landed just in time at 23:59:20 UTC. Our content curation teams will now use the next two weeks to review, rate, sort, and ultimately decide on a large number of submissions. We intend to inform all submitters on November 11th on whether we found a place for them in our Fahrplan.

At the time of our coordination meeting on Sunday there were 690 pending submissions in our system. To put this into perspective: If you would want to just spend a minute to review them all, you would be busy for eleven and a half hours. Another way to look at the numbers is that nearly five percent of 36C3 participants have applied to present a lecture!

Among these submissions the most popular tracks are “Ethics, Society & Politics” with 237, the “Security” track having 194 and the “Science” track seeing 82 submissions.

The following table contrasts the numbers of submissions this year with the numbers of lectures accepted for 35C3. This means that (assuming a similar amount of lectures this year), some teams have to reject 82 percent of their submissions, sometimes heartbreakingly so. The sheer range and creativity of the submissions left us deeply impressed with the energy and wisdom that is sparkling within our community. All without us offering a single cent of speaking fees.

Track	Submissions	Slots
Art & Culture	49	18
Ethics, Society & Politics	237	42
Hardware & Making	49	16
Resilience & Sustainability	61	16
Science	82	21
Security	194	39

To complicate things further: You gave us valuable feedback on our haveyoursay interface, which helped us identify important issues not yet covered by submissions. Of the over 2,000 comments you sent us, around a third was constructive and helpful, with some of them pointing to things other than the conference program where 36C3 could improve. So in addition of the submissions already in frab, some of this year’s content will be filled by invitations by our content curators.

What this all means: Each lecture that makes it into this year’s Fahrplan has prevailed against tough competition and each presenter we could not accept to the conference can be sure that they belong to a group of high quality submissions that had to be turned down solely due to time constraints. We simply do not have more than four days and five stages. With all high quality rejections alone we easily could fill two more conferences. And while our teams often try to explain their decisions together with their rejections, the overwhelming number of submissions makes answering each and everyone of them a time consuming effort. Also, as stated above, the most common reason not to accept a lecture is the simple lack of space in our Fahrplan. So if you receive a rejection email with that reason, please don’t take it as a cheap excuse.

But who are those in charge of selecting 36C3 content? At the moment, lectures are curated by six teams with three to ten main curators and an extended set of reviewers – all in all around sixty people now eagerly working through all those submissions. Some of them have introduced themselves in this blog in the past.

Some team members have introduced themselves on their social media accounts and actively work on encouraging potential speakers to submit (just monitor #36c3 to find out who they are), while others prefer to just help anonymously. And a lot of work is needed: Starting even during CfP submission periods, around 250 lectures needed to be fixed up, their durations, event type or tracks corrected, questions answered by email, co-speakers manually added, and typos corrected. With those bureaucratic nuisances out of the way, all submission now have the best chance to shine by their merits.

Over the next two weeks, our curators will now have to dive into the actual details: analyse the substance, verify claims made in the submissions, clustering them by rough topics, researching presenters regarding their expertise and ability to present – and to verify they do not accidentally invite PR drones, intelligence service, or military personnel on stage. So if you see storms of visitors on your social (business) media accounts, just smile and wave at our curation teams. ;)

Our teams are made up of experts in their respective fields, sometimes working in their domains for decades, who can tap into their vast networks to help estimate a submitter’s history. We want the speakers to present their own work, we want them to present for their enthusiasm for the topic, not money. We want them to be role models, not rock stars. So it is important that our teams find out who the speakers have been working for in the past, where they have presented and how that turned out, and if the conduct in their communities might raise objections to having them on our stages.

In the end we need to find a balance between novelty and community traditions, presentation skills and domain knowledge, entertainment value and soundness, allowing newcomers and tapping into weathered experts, presenting utopists and realists, as well as topics with global impact and niche expertise we think will be important soon.

With so many knobs to turn, we know it’s impossible not to be disappointed with the outcome of certain promising choices, and in the end each 36C3 participant brings a slightly different set of interests, so it might very well be that you find parts of the Fahrplan uninteresting and some lectures worth being replaced with others that you might find more interesting. But keep in mind, there are 16,000 other attendees who might disagree.

One last thing: While the content teams curating the main stages have the longest traditions, they’re by far not the only teams working on content presented at 36C3: As usual there will be self-organised lightning talks, which you can submit at https://c3lt.de/ once its 36C3 section is live. Also there are at least three decentralised stages at 36C3 assemblies that await your submission now: Chaos West will be running a stage at their asssembly, you can submit to here https://fahrplan.chaos-west.de/36c3/cfp, the Freifunk community has kicked off their CfP here https://talks.oio.social/36c3-oio/cfp and, last but not least, ChaosZone just opened theirs as well https://cfp.chaoszone.cz/36c3/cfp.

Oh, and one more thing: If the stars align just right, this year there might be a Hacker Jeopardy again!

36C3: Call for Assemblies

Thu, 24 Oct 2019 16:25:06 +0000

Tl;dr: Read at least the “Important” part and register your assembly on signup.c3assemblies.de as soon as possible, but not later than Sunday, November 24th.

[Ctrl-C, Ctrl-V]

This year we want to apply as much as possible of what we have learned in the last two years in Leipzig. We want to seize the opportunity to consolidate and share experience and knowledge. Therefore, we would like to make as few changes to the previous year as possible. If you’ve been organizing an assembly last year, please expect the same space, requirements, and infrastructure as last year. Even supposedly small deviations sometimes lead to a large overhead in planning and preparation, which we simply can’t afford this year.

As a reminder:

For now, most of the exhibition hall is void. Calm. (Mostly) Unwritten. It’s up to us to create spaces, to fill it with lights, sound and atmosphere, with hacks and gear and people. Make it alive and let the chaos-magic happen. Bring projects to show, ideas to amaze, furniture to lounge – manifest yourself and create a diversity of habitats to connect all the people that make the dream real. Get up, little groups of friends as well as huge amalgamations, and come to Leipzig again. Show your projects, share your ideas, bring your stuff, pose a question, host a session, do workshops and maybe, finally, sit down and listen.

Have in mind that there will be thousands of people in one big hall. Too much noise or light can become an issue. So lets make it a warm, welcoming, and comfortable situation which will be a source of energy for all of us. Considering this, very much anything is possible: You never leave the house without your good old Cray 90? No problem, heavy current is available. Always wanted to build a dome for your assembly? No problem, just keep it “B1 flame resistant”, stay below 30square meters roofed and let us know in your registration. You might have guessed it, there are some technical regulations. Check them first, before you plan big. And no worries, we provide tables and seats as usual for all groups who come with a backpack and smaller things to show and hack. Bring what you have, take a seat, create, get feedback, meet others and team up.

Important

Build-up approval for larger structures will happen. Please don’t arrive with larger structures without telling anyone.
If you need storage space assistance, have questions about build up or delivering your stuff, you get guidance from the LOC via 36C3 [at] c3loc.de.
Music: you’ll get asked while registration if you want to play music (are you sure?!?) in your Assembly. If yes, the Assemblies Team will contact you with details about GEMA registration.
Register until 24.11.2019 on signup.c3assemblies.de
For all questions about assemblies, contact us at 36C3 [at] c3assemblies.de.
Pack your ticket.
So, go call us for a place! Assembly registration ends on Sunday, November 24rd. Better register soon.

C3 Assemblies Team

Ah, one more thing: Please bring your hackspace/community stamp, there are a lot of hacke passports waiting to be stamped :)

36C3: Ressourcen sparen beim Ressourcenschonen: Günstig schlafen.

Sun, 20 Oct 2019 10:18:02 +0000

We now are able to announce that we can offer some low-budget sleeping accommodation in Leipzig. After negotiations with the city administration, we now have two locations available. Both are within walking distance from tram line 16. The locations are school buildings; we are able to use the class rooms for sleeping. Please bring your ohne sleeping bag and ground pad.

The locations will be available from 26th to 31st of December and are open around the clock.

Tickets will be sold at the 36C3 cash desk on site. The price will be €10 per night and person. This year, you can also buy tickets for several nights at once, so you won’t need to buy a new ticket each day.

Details like addresses and directions from the 36C3 venue will be published in the wiki before Congress. If you have further questions please contact us by mail.
