#Militärhatserfunden László Bíró entwickelte 1938 ein Schreibgerät, das spezielle Tinte auf Papier abrollt. Da es auch bei niedrigem Luftdruck funktioniert und damit flugtauglich war, bestellte die Royal Air Force während des 2. Weltkriegs 30.000 Exemplare dieser Kugelschreiber.

Transparency International’s 2025 Corruption Perceptions Index ranked Russia 154th out of 180 countries, 49 places below Ukraine and 82 below the lowest-ranked EU member state. Worth keeping in mind when Moscow next casts itself as a corruption watchdog elsewhere.

6. Oktober 1991 war der Schicksalstag für die Stadt Zadar. 14‘000 serbische Kriegsverbrecher mit über 100 Panzern versuchten die Stadt endlich einzunehmen. 3‘000 schlecht bewaffnete Kroaten stellten sich ihnen entgegen und siegten. Dem gedenken wir hier in Zadar heute.

Positiv ting efter offentliggørelse af CPR-datalæk: Efter i dag vil du kunne bestride ethvert indkøb af tjenester hvor virksomheden udelukkende har identificeret dig med navn/adresse/cpr. Du kan altid påstå det er foretaget af en anden person. Ingen virksomhed kan forsvare og bevise det var dig.

There's a problem we see in cybersecurity where hyperfocus on high-tech threats prevents people from defending against the low-tech methods everyone will try first. Like, before burglars build teleporters, they'll ring all the doorbells, hoping someone buzzes them in.
