I learned some bash from an old-timer who would write an infinite-loop like this:
while :; do
# loop body here
done
This works because the `:` is a way to set a label, and it implicitly returns 0. It's just a weird wrinkle of the language. So, why not do `while true`? On old systems, `true` was not a builtin and would call `/usr/bin/true`. Writing the loop this way saves a process fork on each iteration.On a modern system, you'd be hard pushed to measure the difference, so it really doesn't matter which style you prefer.
I was at Google Cloud Next London yesterday and I hate to disappoint you but _everything_ seemed to be about AI. The keynote was about AI. The decor was all AI generated. Each breakout had to mention AI, to the point where a couple of speakers joked that they _weren't_ going to talk about AI. It was a bit depressing.
Some more modern classrooms had the greenish boards that were a continuous loop that you could roll, but the older ones had black ones that were extremely heavy (maybe slate?). Some of them had a counterbalanced pair on ropes and pulleys in wooden runners, so that when you slid one up the other would come down. I remember in one lesson the ropes snapped and the front-most board came whistling down like a guillotine past the face of the maths teacher and landed with a bang like a gunshot. He was unhurt luckily but was extremely pale and shaken - understandably!
Gallium is an amazing piece of work, and the documentation is superb, but it's starting to show that it's on a very out of date base and there's no sign of a new version for some time. The efforts seem to have slowed down, which is a shame.
It leaves me wondering if the main patches and drivers in the kernel fork could ever be merged upstream. Maybe there's some technical or legal reason why not, or maybe it's just the work required and nobody has the time.
Either way, I hope it remains possible to run old Chromebooks for a while yet! They are often decent, cheap hardware if a little slow.
Our baseline fuel here is called "Premium Unleaded", despite it being the standard fuel and is 95 RON, which should equate to about 90-91 AKI meaning it lines up with your Premium gas.
We also have "Super Unleaded" at the pumps, which is 98 RON and should equate to 93 AKI in the US.
I guess that means we have no equivalent of your regular gas.
FWIW I've never managed to detect any benefit of using the 98 octane fuel, either in performance or fuel consumption. I've never owned a really high performance car, beyond a tweaked Saab 9000 Turbo running a higher boost, and that seemed to be happier on the Premium. I always assume that the 98 octane stuff is just a way of extracting extra money from gullible people, but I have no more proof of that than the anecdata from all the people who buy it and swear by it (probably because of https://en.wikipedia.org/wiki/Choice-supportive_bias )
Are there any public X25 networks still in use? What about telex? Telex over HF? Inmarsat C? Any X400 gateways still running? Can you still send a UUCP mail?
This kind of digital archaeology has a strange fascination to it.
This is a very short-sighted decision and big loss to the network.
