I'm a French (tech) enthusiast.
I like : Travel, party, open HW and SW, domotics, cybersec
I don't like : current climate of fear of strangers/migrants, far right, Brexit

My mom was pissed off that she could not disable Meta's AI bot, so she asked "what's the point of offering this service?" and kept asking "but why? (without lying)" until it replied:

"to achieve global dominance and hegemony over all flux of information and satisfy his supreme egoism."

Then she asked "ok recommend me an ethical alternative to WhatsApp" and we are now chatting on Signal 😆

Other computers elsewhere could "challenge" your computer to prove that it was running an OS and programs that would behave in certain way (for example, that it would block screenshots of confidential messages). This challenge would include a long random number. Your computer's TPM would combine that number with hashes of all the other elements of your computer's operating environment - it's bootloader, OS, etc - and cryptographically sign that using its signing keys.

@jonny Yes! Incredible!!

Here's a video from the paper.. Ants rock!

in switzerland you aren't allowed to have a train with exactly 256 axles because of an integer overflow in the axle counting machine

i wish i could fix my software bugs by making it illegal to cause them

Did you ever wonder why there are 90 degrees in a right angle instead of 100, and 24 hours a day instead of 10?

Perhaps you can blame Napoleon.

In 1795, as part of the French Revolution, the French passed a law requiring that clocks have 10 hours in a day, 100 minutes in an hour, and 100 seconds per minute. They also brought in a system of angles with 400 degrees in a full turn, or 100 degrees in a right angle. With this, the earth would rotate 40 degrees in an hour - and thanks to how the meter was defined, each degree of latitude would be 100 kilometers long.

Of course, changing to the new system would require a lot of work. The economist Condorcet proposed that teams of unemployed wig makers be used to calculate mathematical tables with the new units. Why wig makers? Because after the revolution, aristocrats no longer needed them! (You don't need a wig if you don't have a head.)

The mathematical physicist Laplace was enthusiastic and had his watch converted to the new time. His great five-volume work Traité de Mécanique Céleste was written using the new units of time and angle! But in general the metric system for time and angle did not catch on, despite the law. And in 1806, Napoleon Bonaparte decreed that the French calendar should revert to the old style.
