It is also interesting to read up how this plays into black start plans for the european power grid. You would think solar parks make black starts ... "easy" - just turn them on and have some power, but due to the inverter functio

It can be a good idea to count and record these safety net activations for reporting purposes. If you do so, the discussion of e.g. "Why do we run replicas for our databases" becomes a very simple discussion: It has simplified us

Yeah, I started to incorporate this into my own work. Like, sometimes you can automate 99% of a procedure, except like putting a secret into an so-far not automated secret management solution, or running a terraform apply that requires acce

I'm not going to tell you how long I've at one time been searching for a missing route on the return path of a VPN connection... But damn the lights that went on when I realized that hurt by being too bright.

Then again, speed and performance. At my last job, updating a productive game server cluster took an hour or so with minimal to no customer interruption. Though you could still see and measure how the systems needed another hour or two to g

This is something that would fit right into some dystopian, proto-cyberpunk movie. Like, a bunch of activists need to disable comms of some nightshift guards in an area. So... someone figures out how to put more juice into this thing to pu

Oh that first level caught me off-guard in a good way. Like, at first they fixed that weird error condition how you could detonate the tech lab Einstein is in, which broke a trigger and failed the mission. Now you just blow it up, Einstein

I don't have practical experience with JIRA Cloud Operations, or JIRA on-prem operations, but if I compare on-prem vs SaaS of our own solutions, the answer is scale and focus. If I combine our three internal ticketing systems, we end u

You can also use divide and conquer when dealing with a complex system. Like, traffic going from A to B can turn ... complicated with VPNs and such. You kinda have source firewalls, source routing, connectivity of the source to a router, ro

Weirdly enough, I have thought about this and to a degree, this can be interpreted as normalization of deviancy and normalization of danger. Like, yes, I am a console jockey and prefer working in shells with a tiling window manager, keyboar

With some of these examples, I'd change the API of the lower-level methods. Instead of a (Credentials, err) and the err is a NotFound sometimes, I'd rather make it a (*Credentials, bool, err) so you can have a (creds, found, err),

It's not a binary decision though. Just because the article arrives at overkill for most things in my opinion doesn't mean sentinel errors or wrapping errors in custom types should be avoided at all costs in all situations. In my

Good laws should also "scale out" into unknown complexity and situations. For example, every german has a right to control pictures of their own self, and the way the law was worded, it already applied an idea on the legality of s

I've been noticing similar patterns as well. One instructive example was when I was implementing a terraform provider for an in-house application. This thing can template the boilerplate for a terraform resource implementation in about
