Rules on Pre-existing Work</h3><p><br /></p><p>We do not allow participants to submit pre-existing projects – you may start working on your project once hacking officially begins at event kick-off.</p><p><br /></p><p>You should not be working on your project before the event officially begins. This includes coding, designing assets, etc. Each hack submission will be judged solely on the quality of the work completed during the duration of the hackathon. We require everyone starts building from scratch - if there is a situation where a project/team are porting or continuing existing projects, you may request explicit permission from the ETH Belgrade team in writing before continuing to work on or submit the project.</p><p><br /></p><p>You may use any pre-existing code in your project only after you have notified the ETH Belgrade team in writing about the nature of previously done work and have gotten approval. Further, you need to disclose all relevant information in your submission video, project description, and during judging clarifying what specifically was done before the hackathon. If, upon inspection (during or after the event), you present work that appears to have been completed before the hackathon or does not accurately reflect your project description/video, or extends existing work that was not disclosed, your project is subject to immediate disqualification with full revocation of any prize amounts along with a permanent ban from the ETH Belgrade community and events.</p><p><br /></p><p>By using any pre-existing work (even after written approval), you forfeit the right to be considered as a finalist for the hackathon.</p><p><br /></p><p>In order to ensure that no pre-existing work makes its way into the submission, you must also use version control for your code throughout the course of the event. Any repositories with single commits of large files without proper history will be default assumed to be unqualified unless proven otherwise.</p><p><br /></p><p>Historically, projects that use a majority of pre-existing work do not score as high in the judging as projects which present wholly new and novel approaches - the goal of our hackathons is to create interesting experiments.</p><p><br /></p><h3>3. Media Policy (Photography, Audio &amp; Video Recording)</h3><p><br /></p><p>The following terms and conditions apply to any individual that is attending our in-person events.</p><p><br /></p><p>By attending the ETH Belgrade, you acknowledge and agree that the event (or any part of it) may be photographed or recorded by us or our partners. You agree to permit us, or any third party licensed by us, to use, distribute, broadcast, or otherwise globally disseminate your likeness, name, voice and words in perpetuity in television, radio, film, newspapers, magazines and other media now available and hereafter developed, both before, during and any time after the Conference, and in any form, without any further approval from you or any payment to you. This grant includes, but is not limited to, the right to edit the media, the right to use the media (alone or together with other information), and the right to allow others to use or distribute the media.</p><p><br /></p><p>ETH Belgrade takes the privacy of its attendees seriously and as such we are taking certain measures in an attempt to maintain the individual privacy needs of our attendees. If you would like to opt-out, to be captured within any form of Media, we will ask you to sign an opt-out form on-site at the event and we will ensure that ETH Belgrade and our partners respectfully is aware.</p><p><br /></p><p>Additionally, ETH Belgrade cannot take any responsibility for photographs, video and audio recordings taken by other attendees of the event. If you have any questions regarding this policy, please feel free to reach out to us at <a href="mailto:hackathon@ethbelgrade.rs">hackathon@ethbelgrade.rs</a>.</p>

<h2>What is ETH Belgrade Hackathon?</h2><p>ETH Belgrade Hackathon is a yearly technology event, spanning over two days of non-stop technical talks, workshops, competitions, and coding. For 48 hours straight, around 300 participants can enjoy world-class presentations, demos, community events, and its classic 48-hour coding competition.</p><p><br /></p><h2>Do I get access to ETH Belgrade Conference?</h2><p>All in-person hackathon participants are eligible to receive a free ticket for the ETH Belgrade Conference (June 3-5) with the requirement to show up at the hackathon venue and submit the project. Upon approval for in-person participation, please contact us at hello@ethbelgrade.rs, and we will promptly send you your ticket.<br /><br />In order to ensure participation in the hackathon, all in-person participants will be required to stake 0.05 ETH. </p><p>Note: Failure to attend the hackathon and submit your project will result in loosing your stake</p><p><br /></p><h2>Who can attend ETH Belgrade Hackathon?</h2><p>ETH Belgrade Hackathon is targeted at creative minds with a hacker spirit (in the classical definition of the word). Anyone with a technical profile is welcome to apply, not only engineers (eg. web designers are welcome too).</p><p><br /></p><h2>How are applicants selected?</h2><p>ETH Belgrade Hackathon curators aim at selecting the best, most participative and motivated, programmers and creatives. For this they rely on what candidates fill in their profiles (their pitches and personal bios) and evidence of engagement in previous editions (if applicable). What matters is your potential and your passion for technology, no matter your level of experience.</p><p><br /></p><h2>How much does it cost?</h2><p>ETH Belgrade Hackathon is free for all selected candidates.</p><p><br /></p><h2>Can I register our company employees in bulk?</h2><p>No. Candidates must register and apply individually (they are evaluated and selected individually too, see above).</p><p><br /></p><h2>Do you pay for the atendees' transportation and/or accomodation costs?</h2><p>No. However, there may be discounts and other partnerships. If so, these will be announced in the months leading to the event, so make sure you follow us in one of the social networks where we're present. You can also choose to sleep in the venue. This one is guaranteed, with some caveats (see below).</p><p><br /></p><h2>Can I bring a guest to the event?</h2><p>No. All attendees must apply to the event individually.</p><p><br /></p><h2>Do I have to participate in the 48h programming competition?</h2><p>No. But we do encourage you to participate in something during the event, and not just passively roam around the venue. Fortunately, there are plenty of activities to choose from.</p><p><br /></p><h2>I was selected but can't attend the event, what do I do?</h2><p>Please let us know. Spots are limited and it would be nice if another candidate could go instead (but no, you cannot choose who that candidate might be). And you can still participate online.</p><p><br /></p><h2>When will the schedule be available?</h2><p>A detailed schedule will be available closer to the event, on our website</p><p><br /></p><h2>Will there be a live stream from the event?</h2><p>TBD</p><p><br /></p><h2>Will the talks be recorded?</h2><p>Unless the speaker states otherwise, every talk will be recorded and available online in the weeks following the event.</p><p><br /></p><h2>Is there food and beverages at the event?</h2><p>Food and drinks will be provided free for all attendees. We'll be providing lunch and dinner daily, and there will be random snacks and beverages available 24/7.</p><p><br /></p><h2>Why is the official language English?</h2><p>We have attendees coming from all over the world. English is usually well understood and accepted. Our main motivation is technology and talent, and these are global attributes, so our main 'language' is what we use to code. English is not the only language at the event, though.</p><p><br /></p><h2>Do I get a participation certificate at the end?</h2><p>Yes, we can provide participation certificates on demand in the days following ETH Belgrade Hackathon. Just make sure you actually participate.</p><p><br /></p><h2>Should I arrange for a place to stay?</h2><p>In the spirit of the event, attendees can choose to stay the night at the venue, sleeping in sleeping bags or such. But if this is not your thing, you have many accommodation options elsewhere around. Closer to the event we may announce discounts and partnerships.</p><p><br /></p><h2>Are there hotels nearby?</h2><p>ETH Belgrade Hackathon's venue will be in a very central location in the city, so there are plenty of hotels around.</p><p><br /></p><h2>Are there showers available?</h2><p>The logistics for this are complicated, so don't count on it. Bathrooms are available, but showers may not exist at all or be very limited in time. You'll have to improvise.</p><p><br /></p><h2>I've decided to stay at the venue. Can I bring a small tent to ETH Belgrade Hackathon?</h2><p>Tents are not allowed due to space limitations inside the venue. However we'll do our best to provide you with optimal spots for taking naps.</p><p><br /></p><h2>What about a sleeping bag?</h2><p>This one is allowed, no problems with that.</p><p><br /></p><h2>Is there Wi-Fi at the event?</h2><p>Of course. There will also be a limited number of ethernet outlets in the table area, but teams doing projects for the 48h competition have priority on these.</p><p><br /></p><h2>Will the Wi-Fi be any good this year?</h2><p>The million-dollar question… The organization will provide a world-class setup but, ultimately, this depends on you and your fellow attendees. Bear in mind that hotspots are NOT ALLOWED at the event. Wi-Fi is a shared medium, like a pool, please don't pee in the pool.</p><p><br /></p><h2>I am interested in exhibiting or becoming a sponsor, what do I do?</h2><p>If you are interested in sponsoring ETH Belgrade Hackathon, please contact us at for a prospectus and sponsorship application instructions. You can reach out to <a href="mailto:partnerships@ethbelgrade.rs">partnerships@ethbelgrade.rs</a></p><p><br /></p><h2>I'm a tech guy but I also do recruiting. Is it OK if I talk to someone at ETH Belgrade Hackathon to see if they're interested in working with me?</h2><p>You cannot engage in direct recruitment activities during ETH Belgrade Hackathon. This is one of the core rules of the event. The attendees don't enjoy unsolicited targeting, and we don't want to turn the event into a battlefield for hires. Trust us, it's better for you, not only for attendees. Having said this, it's OK if the interest is mutual and both parties want to talk (meaning the attendee approaches you). It's definitely NOT OK if you're preaching to the crowd or fishing around for interest.</p><p><br /></p><h2>Can I leave a few flyers on the tables to advertise my group/event/company?</h2><p>That would depend on what you're advertising. The only hard rule on this is that you talk to us first at .</p><p><br /></p><h2>Still have questions?</h2><p>Reach out to us on <a href="mailto:hackathon@ethbelgrade.rs">hackathon@ethbelgrade.rs</a></p><p><br /></p><p><br /></p>
