Happy new year!

These are my social media posts from the last three months. I keep them here to reflect on them and also to not lose them. Social media networks come and go and are not under my control, but my domain is here to stay.

These are from Mastodon and LinkedIn. Have a look at my about page for my social media profiles. This list is generated with Gos, my social media platform sharing tool.

First on-call experience in a startup. Doesn't sound a lot of fun! But the lessons were learned! #sre

Reviewing your own PR or MR before asking others to review it makes a lot of sense. Have seen so many silly mistakes which would have been avoided. Saving time for the real reviewer.

Fun with defer in #golang, I did't know, that a defer object can either be heap or stack allocated. And there are some rules for inlining, too.

I have been in incidents. Understandably, everyone wants the issue to be resolved as quickly and others want to know how long TTR will be. IMHO, providing no estimates at all is no solution either. So maybe give a rough estimate but clearly communicate that the estimate is rough and that X, Y, and Z can interfere, meaning there is a chance it will take longer to resolve the incident. Just my thought. What's yours?

Little tips using strings in #golang and I personally think one must look more into the std lib (not just for strings, also for slices, maps,...), there are tons of useful helper functions.

Reading this post about #rust (especially the first part), I think I made a good choice in deciding to dive into #golang instead. There was a point where I wanted to learn a new programming language, and Rust was on my list of choices. I think the Go project does a much better job of deciding what goes into the language and how. What are your thoughts?

The opposite of #ChaosMonkey ... automatically repairing and healing services helping to reduce manual toil work. Runbooks and scripts are only the first step, followed by a fully blown service written in Go. Could be useful, but IMHO why not rather address the root causes of the manual toil work? #sre

I just became a Silver Patreon for OSnews. What is OSnews? It is an independent news site about IT. It is slightly independent and, at times, alternative. I have enjoyed it since my early student days. This one and other projects I financially support are listed here:

Until now, I wasn't aware, that Go is under a BSD-style license (3-clause as it seems). Neat. I don't know why, but I always was under the impression it would be MIT. #bsd #golang

These are some book notes from "Staff Engineer" – there is some really good insight into what is expected from a Staff Engineer and beyond in the industry. I wish I had read the book earlier.

Looking at #Kubernetes, it's pretty much following the Unix way of doing things. It has many tools, but each tool has its own single purpose: DNS, scheduling, container runtime, various controllers, networking, observability, alerting, and more services in the control plane. Everything is managed by different services or plugins, mostly running in their dedicated pods. They don't communicate through pipes, but network sockets, though. #k8s

There has been an outage at the upstream network provider for OpenBSD.Amsterdam (hoster, I am using). This was the first real-world test for my KISS HA setup, and it worked flawlessly! All my sites and services failed over automatically to my other #OpenBSD VM!

Agreeably, writing down with Diagrams helps you to think things more through. And keeps others on the same page. Only worth for projects from a certain size, IMHO.

I like the idea of types in Ruby. Raku is supports that already, but in Ruby, you must specify the types in a separate .rbs file, which is, in my opinion, cumbersome and is a reason not to use it extensively for now. I believe there are efforts to embed the type information in the standard .rb files, and that the .rbs is just an experiment to see how types could work out without introducing changes into the core Ruby language itself right now? #Ruby #RakuLang

So, #Haskell is better suited for general purpose than #Rust? I thought deploying something in Haskell means publishing an academic paper :-) Interesting rant about Rust, though:

At first, functional options add a bit of boilerplate, but they turn out to be quite neat, especially when you have very long parameter lists that need to be made neat and tidy. #golang

In Go, passing pointers are not automatically faster than values. Pointers often force the memory to be allocated on the heap, adding GC overhad. With values, Go can determine whether to put the memory on the stack instead. But with large structs/objects (how you want to call them) or if you want to modify state, then pointers are the semantic to use. #golang

I found that working on multiple side projects concurrently is better than concentrating on just one. This seems inefficient at first, but whenever you tend to lose motivation, you can temporarily switch to another one with full élan. However, remember to stop starting and start finishing. This doesn't mean you should be working on 10+ (and a growing list of) side projects concurrently! Select your projects and commit to finishing them before starting the next thing. For example, my current limit of concurrent side projects is around five.

This is a neat blog post about the Helix text editor, to which I personally switched around a year ago (from NeoVim). I should blog about my experience as well. To summarize: I am using it together with the terminal multiplexer #tmux. It doesn't bother me that Helix is purely terminal-based and therefore everything has to be in the same font. #HelixEditor

I just finished reading all chapters of CPU land: ... not claiming to remember every detail, but it is a great refresher how CPUs and operating systems actually work under the hood when you execute a program, which we tend to forget in our higher abstraction world. I liked the "story" and some of the jokes along the way! Size wise, it is pretty digestable (not talking about books, but only 7 web articles/chapters)! #cpu #linux #unix #kernel #macOS

A plan of mine for next year is not to start any new non-fiction books (or only very few) but to re-read and listen to my favorites, which I read to reflect on and see things from different perspectives. Every time you re-read a book, you gain new insights.
