# Posts from July to December 2025

> Published at 2025-12-31T15:49:06+02:00

Hello there, I wish you all a happy new year! 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.

In `#Golang`, values are actually copied when assigned (boxed) into an interface. That can have performance impact.

We (programmers) all use them (I hope): language servers. LSP stands for Language Server Protocol, which standardizes communication between coding editors or IDEs and language servers, facilitating features like autocompletion, refactoring, linting, error-checking, etc.... It's interesting to look under the hood a little bit to see how your code editor actually communicates with a language server. `#LSP` `#coding` `#programming`

The book "Coders at Work" offers a fascinating glimpse into how programming legends emerged in the early days of computing. I especially enjoyed the personal stories and insights. It would be great to see a new edition reflecting today’s AI and LLM revolution—so much has changed since!

This is similar to my `#dtail` project. It got some features, which dtail doesnt, and dtail has some features, which `#nerdlog` hasnt. But the principle is the same, both tools don't have a centralised log store and both use SSH to connect to the servers (sources of the logs) directly.

I also feel the most comfortable in the `#terminal`. There are a few high-level tools where it doesn't make always a lot of sense like web-browsing most of the web, but for most of the things I do, I prefer the terminal. I think it's a good idea to have a terminal-based interface for most of the things you do. It makes it easier to automate things and to work with other tools.

I have been enjoying lately as an alternative TUI to Claude Code CLI. It is a 100% open-source agentic coding tool, which supports all models from including local ones (e.g. DeepSeek), and has got some nice tweaks like side-by-side diffs and you can also use your favourite text $EDITOR for prompt editing! Highly recommend! `#llm` `#coding` `#programming` `#agentic` `#ai`

What was it like working at GitLab? A scary moment was the deletion of the gitlab.com database, though fortunately, there was a six-hour-old copy on the staging server. More people don't necessarily produce better results. Additionally, Ruby's metaprogramming isn't ideal for large projects. A burnout. And many more insights....

I have learned a lot from the Practical `#AI` `#podcast`, especially from episode 312, which discusses the `#MCP` (model context protocol). Are there any MCP servers you plan to use or to build?

With the help of genai, I could generate this neat small showcase site, of many of my small to medium sized side projects. The projects descriptions were generated by Claude Code CLI with Sonnet 4 based on the git repo contents. The page content by `gitsyncer`, a tool I created (listed on the showcase page as well) and `gemtexter`, which did the HTML generation part (another tool I wrote, listed on the showcase page as well).

When I reach the point where I am trying to recover from panics in Go, something else has already gone wrong with the design of the codebase, IMHO. However, I must admit that my viewpoint may be flawed, as I code small, self-contained tools and rely on as few dependencies as possible. So I rarely rely on 3rd party libs, which may panic (which wouldn’t be nice to begin with; it would be better if they returned errors). `#golang`

Elvish seems to be a neat little shell. It's implemented in `#Golang` and can make use of the great Go standard library. The language is more modern than other shells out there (e.g., supporting nested data structures) and eliminates backward compatibility issues (e.g., awkward string parsing with spaces that often causes problems in traditional shells). Elvish also comes with some neat interactive TUI elements. Furthermore, there will be a whole TUI framework built directly into the shell. If I weren't so deeply intertwined with `#bash` and `#zsh`, I would personally give `#Elvish` a try... Interesting, at least, it is.
