We’ve been saying this for years now, and we’re going to keep saying it until the message finally sinks in: mandatory age verification creates massive, centralized honeypots of sensitive biometric data that will inevitably be breached. Every single time. And every single time it happens, the politicians who mandated these systems and the companies that built them act shocked—shocked! —that collecting enormous databases of government IDs, facial scans, and biometric data from millions of people turns out to be a security nightmare https://www.techdirt.com/2026/02/25/hackers-expose-the-massive-surveillance-stack-hiding-inside-your-age-verification-check/

Gestern ist das Buch mit den Bitzaubersprüchen angekommen. Da muss man als Softwareentwickler einfach mal drin schmökern. Bevor es verboten wird, weil derartiges Wissen nur noch der KI vorbehalten ist.🤣

Da stehen ohne Ende so Sachen drin wie:

"Use the following formula to turn off the rightmost 1-bit in a word, producing 0 if none (e.g., 01011000 01010000):
x & (x – 1)"

Wobei x ein 32Bit-Wert ist.

In German, "altes Wissen", maybe "ancient wisdom", correlates with Fantasy novels or magic or esoteric idiocy.

Here is a case where this may soon be a real thing. Look at this code https://github.com/openjdk/jdk/blob/3d8ffabe5dc6efda10ee7c76cca47e54b5383b48/src/java.base/share/classes/java/lang/Long.java#L1586

to count bits in an 8 byte word. 😀 🤯 It cites "HD, Figure 5-2". I wonder when, in the age of vibe coding, this truly becomes "ancient wisdom" passed on from sourcerer to sourcerer (no typo🙂).

i am wrong about the 120 seconds, that is some other chip (or was it all a dream?). this one is only 6 seconds.


i have three left now.

i should do something like a unit that does the amen break and nothing else.
