bitcoinTrezor Safe 7 (RECENZE A TESTY)
Trezor Safe 7 je nová vlajková loď hardwarových peněženek s otevřeným secure elementem, bezdrátovým Bluetooth připojením a Qi2 nabíjením. V recenzi rozebíráme bezpečnost, design, baterii i software a hodnotíme, zda jde o nejlepší volbu pro bezpečnou správu kryptoměn.
Když se řekne soud nebo soudní jednání, mnoho z nás si představí starobylou soudní síň v historické budově. Naproti dveřím sedí soudce s vážným pohledem, který řeší složité vzájemné spory lidí, kteří se mezi sebou nedohodli jiným způsobem. V článku se dozvíte, v jakých...

Hackers Congress Paralelní Polis 2024 uzavřel dekádu nezávislého hackingu a inovací s odvážnou vizí Second Culture. Co stálo za proměnou Paralelní Polis? A jaký je vývoj hacktivismu, kryptoměn a internetu v boji za svobodnou společnost?
