The thing is, running a good SaaS service requires quite a bit of staff and hard operational skills and a lot of manpower. You know, the kinda stuff people always call useless, zero-value add, blockers and entirely to automate. Sure, we hav

I mean it's entirely fine, at least that's what the company decided. The snark is mostly arising because I recently wrote a little tool to do an inventory of our private docker registry, because storage was getting difficult to ma

Python is very much funny. Like, a ton of our ops-scripting, things have 2-3 direct dependencies and maybe 10 transitive dependencies. And the latter is an actual flask application with pydantic, so a bit outside of "scripting". W

I agree with this. Like, alone, one on one and small groups of 4-6 people are great. I have very enjoyable memories of lounging around with bands after a show, just hanging out, drinking something, shooting some shit about music and life. O

Exactly. If I need to move a few megabytes around, <scp -3> and a coffee or a few simple tickets is a good way. A year ago or so, I needed 600GB moved between two systems ASAP during an outage that'd turn into a money-bleed at 6a

Useful, I didn't know that so far. We don't use bastion servers. My only real use case for ssh agent forwarding is if I need some scp / rsync between two remote systems during emergencies and those systems have no trust via S

As far as I read it, it's about forwarded ssh agents. Basically, if you `ssh -A user@system`, something might be able to execute commands locally. For example, this might turn messy for infrastructures using jump-hosts extensively, i

That's not true in java. You can gradually increase the granularity of unchecked exceptions using subtypes. For example I might initally have AnythingFailedDuringTheQueryException with a Subtype of QueryPreparationException. If I intro

Yeah. The thing is, I like the idea of checked exceptions. You could go ahead and define a number of error situations or error kinds and annotate methods with these checked exceptions to force applications to handle these errors. Like, you
