Posts from January to June 2025



Published at 2025-07-01T22:39:29+03:00

These are my social media posts from the last six 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.

I am currently binge-listening to the Google #SRE ProdCast. It's really great to learn about the stories of individual SREs and their journeys. It is not just about SREs at Google; there are also external guests.

Recently, there was a >5000 LOC #bash codebase at work that reported the progress of a migration, nobody understood it and it was wonky (sometimes it would not return the desired results). On top of that, the coding style was very bad as well (I could rant forever here). The engineer who wrote it left the company. I rewrote it in #Perl in about 300 LOC. Colleagues asked why not Python. Perl is the perfect choice here—it's even in its name: Practical Extraction and Report Language!

Ghostty is a terminal emulator that was recently released publicly as open-source. I love that it works natively on both Linux and macOS; it looks great (font rendering) and is fast and customizable via a config file (which I manage with a config mng system). Ghostty is a passion project written in Zig, the author loved the community so much while working on it that he donated $300k to the Zig Foundation. #terminal #emulator

Go is not an easy programming language. Don't ...



Go is not an easy programming language. Don't confuse easy with simple syntax. I'd agree to this. With the recent addition of Generics to the language I also feel that even the syntax stops being simple.. Also, simplicity is complex (especially under the hood how the language works - there are many mechanics you need to know if you really want to master the language). #golang

How will AI change software engineering (or has it already)? The bottom line is that less experienced engineers may have problems (accepting incomplete or incorrect programs, only reaching 70 percent solutions), while experienced engineers can leverage AI to boost their performance as they know how to fix the remaining 30 percent of the generated code. #ai #engineering #software

I think discussing action items in incident reviews is important. At least the obvious should be captured and noted down. It does not mean that the action items need to be fully refined in the review meeting; that would be out of scope, in my opinion.

Enjoying an APC Power-UPS BX750MI in my #homelab with #FreeBSD and apcupsd. I can easily use the UPS status to auto-shutdown a cluster of FreeBSD machines on a power cut.

However, it won't work when the master is down. #APC #UPS

What I like about Go is that it is still possible to understand what's going on under the hood, whereas in JVM-based languages (for example) or dynamic languages, there are too many optimizations and abstractions. However, you don't need to know too much about how it works under the hood in Go (like memory management in C). It's just the fact that you can—you have a choice. #golang

I found that working on multiple side projects concurrently is better than concentrating on just one. This seems inefficient, but if you to lose motivation, you can temporarily switch to another one with full élan. Remember to stop starting and start finishing. This doesn't mean you should be working on 10+ 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.

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?

With the advent of AI and LLMs, I have observed that being able to type quickly has become even more important for engineers.

I understand that Kubernetes is not for everyone, but it still seems to be the new default for everything newly built. Despite the fact that Kubernetes is complex to maintain and use, there is still a lot of SRE/DevOps talent out there who have it on their CVs, which contributes significantly to the supportability of the infrastructure and the applications running on it. This way, you don't have to teach every new engineer your "own way" infrastructure. It's like a standard language of infrastructure that many people speak. However, Kubernetes should not be the default solution for everything, in my opinion. #kubernetes #k8s
