Hackaday conference in Belgrade 26th of May


First Hackaday conference outside US was held in Belgrade/Serbia in May 23rd 2016.

It was very interesting event with lot of talks and good food and drinks.

This year there will be second conference in May 26th again in Belgrade/Serbia. If you wonder why all Hackaday conferences are at one and same place the secret is that Hackaday owner Supply Frame Inc CEO is from Serbian descent, Hackaday have team and development lab setup in Belgrade, so it’s native choice.

Serbia did not join EU yet (hopefully this will happen soon!), so this is not so good news for EU travelers. While I could book my ticket for FOSDEM with Ryanair Plovdiv-Bruxelles and Bruxelles-Plovdiv for EUR 9.95 in each direction (Plovdiv – Bruxelles is 2300 km distance) , there is no such option for Belgrade and normal flight cost EUR 200 although Belgrade is just 550 km away from Plovdiv. This is the magic of the European Union single market and air space! Another issue is the roaming taxes in Serbia are ridiculous and cost something like EUR 3-5 per minute, while all telecom operators roaming charges in EU are less than EUR 0.15 per minute, so be careful when talk in Serbia with cell phone or buy local SIM card.

Hackaday has opened proposals for lectures and start selling early bird tickets for EUR 23.45 I guess this odd number come from $30 converted to USD/EUR exchange rate.

For this event Voja Antonic made special badge in the form of BASIC computer, so with the ticket you will get this beauty:
