Worth knowing from Apple's 149555 note: a macOS update can put Apple's copy of cert.pem back. Anyone who removed those roots by hand should rerun the step 4 check after installing 27.2.

If anyone was wondering, no, macOS 27.2 update today does not appear to remove "emSign ECC Root CA - G3" and "AAA Certificate Services" roots from /etc/ssl/cert.pem. If I had to guess 27.2 was "done" several days ago.

A fun thing I’ve had a couple of times from “lying” to models: depending on the task, if it figures out you lied to it, more than once I’ve had a model try to delete all evidence it was doing something that it originally said it was not going to do.

I don’t like lying to the models. Somehow this makes me feel really guilty. So maybe I’ll just build a tool.

I’m there!

“X” marks the spot. I find that putting two strings corner to corner to find the center of a room to be very effective and easier than a tape measure.

Putting aside the “access” problem, medicine, vaccines, care.

Social media loves talking about how everything is getting worse. But what’s something that you’ve seen get _better_ in your lifetime?

TIL a lot of people judge an egg’s quality by yolk color (orange > yellow) but the color is mostly just a product of what the chicken is fed. Like, farmers are feeding hens paprika and carotenoids now for orange yolks.

@blowdart.me if I have to see this image so do you.

70 percent of the internet was vulnerable yesterday to very bad security flaws inside a coding language. Turns out, *one volunteer* is mostly responsible for maintaining that code & helping push updates. Yesterday Ondřej Surý saved the internet. So I called him up www.theatlantic.com/technology/2...

turns out eMudhra - which just got out of the cert business altogether - isn't just a problem for Indian customers; the G3 root that signed the dodgy keys, that Firefox already distrusts, that Google will distrust on the 27th is what a bunch of US university certs chain up to

Last night 43 of 57 large universities still had current certs on that chain. Minnesota, Michigan, Washington and UC San Diego had 500+ each. I just published our writeup on it. www.certkit.io/blog/emudhra...

The amount of misinformation about the eMudhra cert situation and its impact is depressing. The impact is real, significant, and important yet some people are out there still just Making Shit Up.

@xkcd.com must have a pretty good signal on “Today someone did something cryptographically dumb” based on traffic to the random dice rolling 4 comic.

Not to say that the distrust is because of those compliance issues, just noting some interesting bits here and there.

It's time to drop support for Windows PowerShell, and move to PowerShell 7. Yes, even if it doesn't yet ship in-box with Windows Server. Just install it by default - you can still use WinRM, no need to switch to SSH. .NET Framework is *ancient* and lacks a decade of improvements

I think this is still one of ATProto / Bluesky’s superpowers. It’s API is open, it has to be! X closed* theirs and so many cool ideas, apps, etc. closed with it. *Unless you have a giant pile of money

Atmosphere update: atproto apps are growing 20% month over month, and last week we passed 1,000 daily active apps.

At a Halloween event with the 3 year old and they are giving out candy for hitting a ball with a bat. All of the sudden my kid turns in to Ty Cobb when candy is on the line.

I have never seen it in the wild until today but this dude in the coffee shop brought what amounts to my entire workspace of computer shit with him. Laptop, portable external monitor, a mouse, the works. Obnoxiously, using two tables for all his shit.

> NIST elliptic curve cryptography, which I would now personally recommend over Curve25519/Ed25519/X25519. Fascinating

Filippo Valsorda@filippo.abyssdomain.expert

Anthropic found the origin of the NIST elliptic curve seeds: they were generated with drand48()! No one was seriously worried, but this should put some FUD to rest, completing the NIST ECC rehabilitation arc… just in time to be retired in favor of PQ. Also, we raised $36 Ki for ISRG. Yay!

I think this is a really good example of how “personal-use” things AI can be extremely good at and, without it, probably wouldn’t exist otherwise. Creating hyper-tailored things for super specific purposes is feasible now.

Still working out some kinks but I thought I'd share for people in a similar situation. We have a mostly nonverbal autistic kid who can actually do sight-words OK. I realized I could make music videos with exactly his sight-word set and favorite topics using Claude (the model was sonnet 5.5).
