Decentralized Systems & Applications

On Saturday, 27th of June, we’re going to meet and discuss the *The Power of the Powerless* by Václav Havel, an influential book that has become a key text of dissident thought in communist Eastern Europe. Written in 1978, Havel’s book explores how authoritarian systems sustain themselves not only through force, but through conformity, fear, and everyday participation in lies. What does it mean to ‘live within the truth’? Can ordinary people resist oppressive systems, even when they seem powerless? And what forms of responsibility do individuals bear in political life? Although written under late socialism in Czechoslovakia, Havel’s reflections remain strikingly relevant today. How do ideology, bureaucracy, media, and social pressure shape our behaviour? Are modern societies immune to the dynamics Havel describes – or do they simply take different forms? Václav Havel (1936–2011) was a Czech playwright, dissident, political thinker, and statesman. A leading figure of the democratic opposition during communist rule, he later became the last President of Czechoslovakia and the first President of the Czech Republic. *** Anyone is welcome to join! Before the meeting, please read the book (it’s around 100 pages long), think about it, and note any passages you find especially interesting, challenging, or worth discussing. We’ll share our thoughts and interpretations during the meeting. Organizational notes: 📍 Attendance is free ⏳ Spots are limited 🔗 Please register via the app so we know how many people to expect and can reserve a table accordingly

**The ABSOLUTE BEST place to be on a Saturday night in Prague! 🤩🍹** Every Saturday, we take over a stunning venue right in the city center and give you **total freedom to mingle at your own pace**. There’s no hand-holding, name tags, or stiff corporate icebreakers here—just a room full of great people skipping the small talk and **sparking real connections**. ✨ During peak hours, the room gets **TOTALLY MAGNETIC** and sometimes even beautifully chaotic. And to be honest, we love it exactly like this! Bar Nomads is all about pure social flow! ⚡🔥 If that’s your vibe, drop the city masks and dive headfirst into our lovely Hoffa madness. You’ll leave feeling energized, deeply connected, and a little bit more like **a true Praguer.** 😎🤙 📍 **Hoffa Bar:** https://maps.app.goo.gl/HRPxX9ruUHphZ4u37

NOTE THE TIME CHANGE TO 9AM Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun. This is where we meet: http://photos2.meetupstatic.com/photos/event/7/7/3/1/600_447930513.jpeg

Filozofování o životě a o všem ostatním pro všechny, bez vstupného a bez přihlášky: Co si přejete, s čím si lámete hlavu, co Vás nenechá spát, o čem dumáte, o čem sníte, co Vám vrtá hlavou, čeho se bojíte, na co vzpomínáte, o čem přemýšlíte? Nenechte tyto věci jen pro sebe, zkuste rozhovor s jinými lidmi. U nás nejde jen o to, si popovídat, o to taky, ale to máte i jinde. U našeho stolu se pokusíme, spolu *filozofovat*. Nejdříve se dohodneme, jaké téma budeme diskutovat, a pak se do toho pustíme, budeme přemýšlet, rozmýšlet, promýšlet a zamýšlet se, až se nám z toho bude točit hlava, přitom nám budou podporou filozofové všech věků, abychom jí neztratili, tu hlavu. Ani byste nevěřili, jak filozofie může být osvěžující…
