Im Rahmen des Aktionstags "genialsozial" besuchte uns ein Schüler des Romain-Rolland-Gymnasiums Dresden. Einen Tag lang arbeitete er bei uns im Bereich Usability Testing.

Here is my highly opinionated list of resources to learn development concepts “beyond if-else” applicable to multiple programming languages.

With docker-slim I reduced the size of my Docker image from 998MB to 92MB. Here I describe how to do that.

I've just recently stumbled over a composer configuration which changed my life (for the better): preferred-install source.

On one of our sites where we employ "classical" deployment (without docker containers), we have found weird problems related to the deployment: Sometimes, the updated markup was not delivered by the server, but the server was still delivering the old markup. This story is a deep-dive of what we found, what we learned and how we finally fixed it. In the end, it's just a tiny NGINX configuration change ;-)

I want to share my experience with the open-source photo gallery HomeGallery suitable to host tens of thousands of photos on a Raspberry Pi for access with different screen-sizes (desktop computers and smartphone). I absolutely love it! The UI concept and the performance are great.

Folge Nummer 42 unseres Sandpapier Podcasts: Letztes Mal sprachen wir in der Auftaktfolge unserer #2028 Reihe darüber, was wir innerhalb von Sandstorm und auch "da draußen" für ökologische, individuelle und soziale Nachhaltigkeit tun und wo wir damit noch hin wollen. Dieses Mal schauen wir in unsere Kernprozesse.

Subtle changes in the SQL queries and schema can have huge impacts on performance of the application. This is a showcase for one particular pitfall.

Writing an online Mandelbrot Set has been on my mind for quiet some time now. The code is meant to be a more complex "Hello World" WebAssembly program. After all: we must deal with complex numbers.

Wir haben uns dazu entschieden, keine Pakete durch die Länder zu schicken, sondern etwas für uns alle zu tun. Getreu dem Motto „Spenden statt Schenken" haben wir in Kooperation mit Wilderness International ein Stück Regenwald in Peru gekauft und so vor der Abholzung geschützt.

Ein Trick für iTerm2, wie man visuell merkt, ob man auf dem lokalen Server oder per SSH unterwegs ist.

A couple of days ago our monitoring notified us about high disk usage on our GitLab server. Some investigating and a little script helped us to reclaim a lot of disk space.

Wir freuen uns sehr, Sandra als neue Sandstormerin begrüßen zu dürfen!

Upgrading React Native projects in practice is not so easy - our workflow makes it well workable.

Let's install Pi-hole on your Raspberry Pi server (prior blog post) and let it eat ads. In this blog post I explain the installation and configuration of the Pi-hole and how to use it LAN-wide.

In einer Spezialfolge sprechen Karo und Tobias darüber, was sich hinter "Sandstorm 2028" verbirgt. Dies ist der Beginn unserer Reise hin zu mehr Nachhaltigkeit...

I walk you through my way of setting up a new Raspberry Pi as a server. Note that this is only one of many, many ways to setup a server. I choose this one because I find it easy and the result "good enough" to get started.

We are building our own 2 WAN gateway on a Banana Pi R2. I want to share my experience during the installation of the OS until the first SSH connection.

In dieser Folge des Sandpapierpodcasts sprechen Theo und Tobias über das Konzept Cool Down. Cool Down ist für uns eine Pause vom Projektalltag. Wir nehmen uns bewusst Zeit zum Lernen, Ausprobieren, Runterkommen. Mal wieder inspiriert von...

Quite some time ago we tried out BigBlueButton and we still use it today. Sometimes for full-fledged meeting with recording of session. Sometimes for opt-in video only when we talk via another tool. Now we decided to update to BigBlueButton 2.3 and install it on a new server with a fresh operating system.

Wir freuen uns sehr, Hanno als neuen BA-Studenten für Medieninformatik begrüßen zu dürfen!
