I got kicked off LinkedIn this week. Apparently there was "suspicious behaviour" on my account. To get back in, I needed to go through Persona's digital ID check (this, despite the fact that I've got a Persona-powered verification on my LinkedIn, less than six months old).

After looping around many times identifying which way up a picture of a dog was and repeatedly photographing myself, my passport, and my driving license, I eventually got back in. Personally, I suspect they just rolled out some Online Safety Act functionality and it immediately tripped over my unusual name.

But let this be a reminder to anybody who (unlike me) depends upon their account in a social network: it can be taken away in a moment and be laborious (or impossible) to get back. If you care about your online presence, you should own your own domain name; simple as that!

I spent most of a day getting my new development environment set up, because I kept hitting issues that nobody at my new employer had experienced before. A "perfect storm" of coincidences that conspired together to completely wreck my chance of a simple setup.

The factors?
- Apple's M4 processors remove the SVE architecture and its instruction set, which was present in the M1 through M3
- The Colima dockerisation tool still reports to arm64 containers that SVE is available
- Java < 24 will, by default, use SVE for some functions if it's told that it's available
- Opensearch 2.x will not run on Java > 23

If ANY ONE of those statements were not true, I wouldn't have had any trouble. But the combination of all four of them meant that I was getting proper segfault-death crashes.

I blame Apple. Who removes instructions from a processor within the same family‽ (I'm sure that in reality there's probably some important reason for it that's beyond my ken, but still!)

Off to my first day at Firstup. Gotta have an induction: get my ID badge, learn where the toilets are, how to refill the coffee machine, and all that jazz.

Except, of course, none of those steps will be part of my induction. Because, yet again, I've taken a remote-first position. I'm 100% sold that, for me, remote/distributed work helps me bring my most-productive self. It might not be for everybody, but it's great for me.

And now: I'm going to find out where the water cooler is. No, wait... some other thing!
