When landing on the Moon, the astronauts watched an instrument called the FDAI that showed the spacecraft's orientation. The ball inside the Flight Director/Attitude Indicator rotated in three axes as the Lunar Module rotated. Let's look inside and see how it works. 1/N

If you are zip-tied after being detained, and have any numbness/tingling/weakness in the wrists/hands, DEMAND medical care. DEMAND an ER visit. Do whatever you can to get it documented. The “temporary” nerve injury is not always temporary. You may not know for weeks. It can be disabling. I see it. Not often, but occasionally. When dipshits mass-arrest people and use non-standard restraints with no re-assessment, people get hurt. Make sure you have a paper trail.

I overlaid two contiguous files and two reserved storage ranges onto up to five GPT partitions, to allow a non-partition-supporting operating system to coexist with EFI and its required GPT partitioning, and with the two files placed atop the boot and maintenance partitions.

This removed the last chance for Apple engineers to have meaningful, unscripted, unmonitored contact with actual customers, and the fact this has been the norm for the last five years shows in how steadily out of touch your products have become.

Suck it up and actually talk to people. Do a real conference and touch grass, as it were.

With macOS and app sandboxing, and (a lack of) full disk access for Terminal app (and the defaults command), and Hilarity Ensues…

How the security-related pieces of macOS can sometimes fit together in unexpected and unhelpful ways:

This particular case for Safari browser, but most any sandboxed app will follow this pattern.

The advent of Apple Intelligence has greatly improved the creative-corruption capabilities of “predictive” text.

I’m having to watch for wholesale changes in what was typed.

While auto-corrupt and predictive text usually works and usually fixes typos, sometimes the text (due to LLM hallucinations?) can be entirely unexpected.

Probably time for some sites to add firewall rules that trigger a log or an alert for any attempts to access the Java and Oracle domains.

These rules to detect and report any rogue installs.

What sorts of rogue installs can exist?

One of the local Java dependencies had been the (now long replaced) Zyxel firewall.

The firewall web UI used Java to generate a display of the port status. (AKA: hunting flies with anvils.)

We (university IT Services) sent out an all staff and student email telling everyone to uninstall any Oracle Java products from their machines. Apparently the licensing terms were such that if Oracle came on-site and performed an audit, one single installation of a Java product (even just a JRE) would result in us having to buy a site-license (for approximately 25k users). There is no option for per install licensing 🤨 https://www.theregister.com/2025/06/13/jisc_java_oracle/
