A really “inspirational” Google ad about a young girl who’s inspired by an Olympic athlete so her dad asks Google’s Gemini AI to write the athlete a letter from his daughter.

It’s actually an effective anti-AI ad which plays to the fear AI drains the creativity and honesty out of human communication. 🤦🏾‍♂️

someone just shared this picture with me and I am so mad this is a thing that somebody thought was a good idea, or even not a terrible idea

Shout outs to my non-Microsoft friends who gave me input and technical editing, appreciate you!

I can count on one hand the number of my clients over the past couple of years who haven't either over-architected for scale or were unnecessarily concerned about it.

You don't need to understand Distributional Little's Law to figure this out, it's obvious with primary school level math.

Interesting nugget in this story on the historic mass recall to replace 100,000 engines in Toyota trucks & Lexus SUVs: When Toyota first reported the problem to the government, the total # of vehicles hadn't been determined, but NHTSA's website required an "integer value" in the percentage of vehicles impacted field, but "1" also meant "unknown".

AWS in GovcCoud US-East _accidentally_ upgrading MySQL from 5.7.X to 8.X.

DevOpsBorat was right. Error is human, automatically upgrading a database fleet to a new major MySQL version is #devops .

I once had the pleasure of working with @mslaviero, and miss his smarts and wit. This blog post on how @ThinkstCanary architects for security is worth a read for many reasons - but the biting insight delivered with a chuckle is what I’m most enjoying.

Gave a burst of new talks over the past week, including intros to (1) patents, (2) timing variations in crypto code, (3) modern tools to avoid bugs in rewriting snippets to run in constant time, and, on the more mathematical side, (4) cola cryptography: https://cr.yp.to/talks.html

The recent post reminded me of

With classics like:

"Compilers don't warn Bruce Schneier, Bruce Schneier warns compilers."

"Bruce Schneier mounts chosen-ciphertext attacks without choosing the ciphertext."

Binarly's PKFail:
Yet another way that SecureBoot is broken. This time it's due to manufacturers like Acer, Dell, Gigabyte, Fujitsu, HP, Intel, Lenovo, and SuperMicro using test/public keys to secure the kingdom. (The Platform Key (PK))

Surely my no-name (Beelink) cheapo Chinese PC does the right thing, right?

Oh...
