Living in London/Paris, earning well (~being affected by the sanction), having "anti-Putin opinion" yet doing nothing lacks any merit. Who else would do the actual work of changing the regime if not the locals?
Why not limit the funds a Russian citizen can place at EU banks? It's a signal to all the wealthy that they do not have an easy "plan b" once shit hits the fan, and incentives them to create a more stable environment.
Also, why not sanction well-known Russia-paid European spies like Gerhard Schröder and limit their finances within the EU. The Hungarian national TV just aired a pro-russian programme, where an "expert" named Georg Spöttle put Zelensky and Hitler in parallel. Why not sanction these guys first?
Adopting k8s for our 2-people startup early on was a huge win: as this tech isn't likely to get superseded anytime soon, we invested happily into CI/CD and logging & monitoring pipelines on it. We have ~daily release cycles now with a very low count of user-affecting mistakes.
We definitely would have skipped this investment with other low-tech (scp) or proprietary tech stacks (ecs, ebs, etc).
