Recently I got inspired to try out the December Adventure and so here we are. ;-)

It has been nearly two years now since I switched from Sylpheed to aerc as my daily driver for email.

Some of us prefer to use console (text terminal) tools for productivity and that is just fine.

The default expectation of the wonderful aerc email client is the usage of abook as address book.

The trouble started when emails were coming in claiming first “Fail” and later “DegradedArray” events of a software raid running on a Debian Linux server.

With the release of version 1.9.0 sbt is deprecating the IntegrationTest configuration.

For quite a long time PostgreSQL supports authentication via SCRAM-SHA-256 now, so migrating is long overdue.

VCS usually have hooks into which commands can be “plugged” to be executed automatically upon certain events and the great darcs is no exception.

There are scenarios when you might want to automatically create snapshots via ZFS to have a backup ready if needed.

It is nice if your CI/CD pipeline does also check for code format compliance but sometimes you may want to have feedback earlier or even prevent unformatted code to enter the repository.

Sometime you need or want to move a commit or several of them between different git branches.

For some time now the usage of metals for Scala development is no longer a choice for the brave but could be considered the “should be default” variant.

Gitea is a nice alternative for a self hosted Git service.

Some days ago I ran my regular pkg upgrade command under FreeBSD and lost my input devices under X11 (Xorg). :-( However with help from several people we were able to find a fix for it.

My colleague Maali discovered an issue that raises its ugly head if you’re using the typesafe config library in combination with Cats effect and certain versions of SBT.

Today I finished my book about “Pure functional HTTP APIs in Scala”!

Bereits vor einiger Zeit wurde die Gruppe LambdaHRO von mir mitgegründet.

Quite some time ago I started noticing that the mouse in dosbox was starting to “jump” occasionally.

Unser Buch “Come out and Play” über Webentwicklung mit Scala, Scala.js, Akka und dem Play Framework ist fertig.

Was lange währt, wird endlich gut - so sagt man jedenfalls. ;-) Heute haben wir die erste Version unseres Buches “Come out and Play” veröffentlicht: https://leanpub.com/comeoutandplay.

Das Thema Datensicherung (Backup) ist ein großes und jeder, der sich ernsthafter mit Computertechnik beschäftigt, sollte damit Berührung gehabt haben.

If you would like to use neovim for their Scala development workflow then this guide may get you started.

Because there are way to many options for git to remember it is feasible to have a template file for the .gitconfig which is usually located in the home directory.

If you’re upgrading your FreeBSD installation to 11.2-RELEASE please ensure that you disable custom kernel modules first.

Der Film “Rogue One” ist ein Science-Fiction aus dem Jahr 2016 und erzählt die Vorgeschichte zum Film “Star Wars” (Episode IV).

If you’re running confluence behind a reverse proxy then you might stumble upon an issue that prevents firefox from working correctly.

If you work with sbt (or activator) and want to restrict the resolvers to the ones that you choose then you might get frustrated that overriding the resolvers setting does not suffice.

If you happen to use the fine postgres extension for slick named slick-pg then you might stumble into an issue where the compiler complains about missing implicits for column types that should be provided by slick-pg if you override the api method of the…

If you ever need to change the author of a commit (or several) within a git repository, you can use the following script:

If you upgrade cups on your FreeBSD installation or maybe you install some foomatic packages this may lead to the removal of the cups-filters package.

If you’re using the fabulous wartremover to keep your code cleaner and are using akka too then you might have stumpled upon the following warning from wartremover:
