honk 1.0
It’s been four years since honk 0.1. Before that, the preview, and shortly after the followup. But finally, after a long journey, we’ve reached honk 1.0. (Narrator: honk is a microblog server that federates with other servers via ActivityPub.)
Once I needed to release 0.9.91 to fix a bug I realized we were getting very low on reserve version space. There’s no particular milestone that makes 1.0 a real release, although it does include some good stuff. But some stuff is still kinda in its 0.7 state. So this post is not really an analysis of the recent changelog entries.
Instead it’s about the many ways honk has won, and the many ways others have lost. It may also help to explain why some fediverse things work or don’t work the way they do. Totally unbiased, as you should expect from an objective critic.

Mastering Grouped Counting in R: A Comprehensive Guide
As data-driven decision-making becomes more critical in various fields, the ability to extract valuable insights from datasets has never been more important. One common task is to calculate counts by group, which can shed light on trends and patterns within your data. In this guide, we’ll explore three different approaches to achieve this using the powerful R programming language. So, let’s dive into the world of grouped counting with the help of the classic mtcars dataset!

Symmetric Properties
If you take a square and rotate it 90 degrees, you get back an identical square. We say the square is rotationally symmetric. Similarly, if you reflect it across an axis, you also get the same square. Since "reflectionally" isn't a word, we can more generally say it's "symmetric under reflection".

FreeBSD on FreeIPA/IDM with Poudriere Repo
In both earlier attempts I compiled and configured everything by hand – at it was a very interactive time consuming process. This time – after having some poudriere(8) experience – Simple FreeBSD Poudriere Harvester Guide – as shared here – I will now automate customized FreeIPA/IDM packages creation in a FreeBSD Poudriere tool.
