It was September 2014, and I needed to procrastinate a University exam. Looking for something I could mentally categorize under “useful”, I happened upon Taskwarrior, and it has been running my life ever since. In this post, I will describe what Taskwarrior is and how I’m using it, as well as my migration from Taskwarrior 2.6 and Taskd to the new Taskwarrior 3.4 and taskchampion-sync-server. In short, Taskwarrior is a command line task management system. ...
I’d like to talk about a great website I found a little while ago, exercism.org. I discovered it a while back, when I was trying to learn Elixir. That project got interrupted pretty badly by my Kubernetes migration, but I’m now back to it. I still want to learn a language a bit more suited to web development, but I’ve switched to Golang now. Mostly because, when I started looking at Elixir again, I had forgotten pretty much everything again. Plus, I also never really wrapped my head around functional programming. ...
As promised in my previous post, now onto the second category of podcasts I’m listening to: History podcasts. I love history, in all it’s periods and countries. I even went so far as taking AP history in high school and did pretty well with it. Lots of my YouTube consumption are historical channels. And so it is also for podcasts. In fact, the very first podcast I started listening to, way back in 2019, was a history podcast. ...
In the interest of expanding my writing a bit, I always wanted to write about the media I’m consuming a bit more, and I will start with a small series of posts on my favorite podcasts. To me, there are roughly three kinds of podcasts I listen to. The first one is history podcasts - just some narrator telling me interesting tidbits from history. I will write about all of those in the next post. The second kind are what I’d call “current affairs” podcasts, e.g. news, politics, Open Source/Linux talk podcasts and such. ...
Wherein I set up some Prometheus metrics gathering from Ceph’s S3 RGW and build a dashboard to show the data. I like metrics. And dashboards. And plots. And one of the things I’ve been missing up to now was data from Ceph’s RadosGateway. That’s the Ceph daemon which provides an S3 (and Swift) compatible API for Ceph clusters. While Rook, the tool I’m using to deploy Ceph in my k8s cluster, already wires up Ceph’s own exporters to be scraped by a Prometheus Operator, that does not include S3 data. My main interest here is the development of bucket sizes over time, so I can see early when something is misconfigured. Up to now, the only indicator I had was the size of the pool backing the RadosGW, which currently stands at 1.42 TB, which makes it the second-largest pool in my cluster. ...
