When being Hitler’s guard was a literal drag…

Quick segue here, but this story is too good. In 1942, Die Grosse Liebe came out, Goebbel’s Magnum Opus other than Triumph of the Will. The Nazi propaganda minister was really into this movie and wanted it to be a huge success swaying the emotions of the German people back to believe in winning the […]
Monky Business: Creating a Cistercian Numerals Generator
13 janvier 2026
In the 13th century Cistercian monks came up with a way to show the numbers from 1 to 9999 as a single character. The way it works is to add the lines of different characters to each other until the number is reached. So, if you want to show 161, you take the 1, the […]

AI is Dunning-Kruger as a service
30 octobre 2025
On January 6th, 1995 two bank robbers in Pittsburgh confused law enforcement by not making any attempts to conceal their faces but instead brazenly looking at security cameras as if they were invisible. The reason is that they actually thought they were. Clifton Earl Johnson had convinced his fellow in crime, McArthur Wheeler that covering […]
When people turn data into HTML tables using JavaScript, they either use the DOM methods (createElement() and the likes), but most of the time just append a huge string and use innerHTML, which always is a security concern. However, did you know that HTML tables also have an old, forgotten API ? Using this one, […]
