We have just one Scala service - it's not a language we use day to day. We're almost entirely Go, but do use other languages where it makes sense to - usually because there's a useful library, or great tooling / communit

Specifically for the Apple watch, people did with the original, but the newest model has enough battery to survive longer than 24 hours. I sleep with mine on for (3rd party) sleep tracking and charge it while I'm in the shower.

The problem is it feels like they're using this case, where the guy is obviously guilty, to set a precedent despite having enough evidence to convict him already. Maybe next time they won't have evidence, but there's a handy

Was it contactless? I've found staff really aren't used to online contactless transactions which can decline, they just take the "card read successfully" beep to mean transaction approved. I've (accidentally) had a
