I personally work a lot with Org Mode, but collaborate on bigger projects with other people through proprietary tools. Some of them are very good for collaboration like Pivotal Tracker. So it totally makes sense to use them in heterogeneous teams! In fact, very often it is me introducing them into the team.

However, for my workflow (which is based on GTD) it is important to know that I have all my pending tasks visible in one place. In fact, that's one of the great features of Org Mode - I have my meeting minutes, tasks with links to resources like...

Über die letzten drei Tage haben wir ein wunderbar sonniges Code Retreat mit dem Team unseres Inkubators QuickShift in Ronco, Italien geniessen können.

Im Freien entwickelt es sich am Besten!

Feinster italienischer Kafi macht gute Stimmung.

Vom Retreat Haus hat es einen wunderbaren Ausblick auf den Lago Maggiore

Von Business-Entscheidungen hin zu Architektur und Entwicklung - alle sind konzentriert an der Arbeit!

Frühaufsteher bekommen jeden Morgen ein wunderbares Spektakel geschenkt.

If you recently upgraded the Slack Desktop App on Debian and now are wondering what happened to your automatic HiDPI recognition: Don't worry any further. It's a little peculiar, since this regression doesn't seem to be well documented on the net. However, the solution is easy. Slack on the Desktop is an Electron app - therefore it generally supports the same flags that other Electon Apps (like Spotify) support and Electron has a flag since 2014 --force-device-scale-factor. On my Macbook Pro, I'm using a scale-factor of 1.5.

Here's a little convenience wrapper around the slack binary to always start Slack...

TL;DR The following snippet added to you ~/.zshrc will recognize project folders you changed to, so that when you create new shells (i.e. through opening a terminal) it changes to the last used project automatically. Please find the complete snippet at the end of this post.

Some projects have a lot of processes. While there are tools for orchestrating the startup of applications that require multiple processes, sometimes it just more convenient to open terminals for each of those processes. But having opened multiple terminals, it would be cumbersome to have to change to the project's directory on each of those...

Lean back and relax while enjoying a deep dive into the wonderful world of the Emacs editor. Emacs renaissance came with the advent of Clojure and undoubtedly is the most popular editor among Clojurians today. Of course there is a lot more you can do with Emacs, but much like playing an instrument, great skill only comes with practice.

You neither need to be an Emacs user nor a Clojure Programmer and neither do you need to contemplate about becoming one either to enjoy this talk. Much like you don't become a professional musician by attending a concert, but it might...

Erste Einsatzpläne mit QuickShift

QuickShift Logo

Die Entwicklung von QuickShift schreitet weiter voran. Wir freuen uns, mitteilen zu können, dass wir mit dem ersten Gastro-Unternehmen den Betrieb aufnehmen! Das Grübeln über Einsatzpläne kann auch bei Ihnen bald ein Ende haben. Im Verlaufe des Jahres werden wir immer mehr Betriebe aufnehmen. Wir würden uns freuen, wenn auch Ihr Betrieb diese Gelegenheit am Schopf packt!

Jedes Gastro-Unternehmen ist individuell

Gewisse Bedingungen bei der Erstellung von Einsatzplänen sind für alle Betriebe gleich. Dazu zählt beispielsweise das Einhalten der LGAV-Bedingungen. Auch versuchen die meisten Betriebe...

Testing deserves and requires it's own spot in the development plan. It is understandable to only plan ahead sparingly, because many developers dislike testing. They tend to test gently, subconsciously knowing where the code will break and avoiding the weak spots. However, with the proper training and setup, you can find your bugs now and not later.

Finding bugs is somewhat like fishing with a net. At 200ok, we use fine, small nets (unit tests) to catch small fish, and big, coarse nets (integration tests) to catch the killer sharks.

We encourage you to start testing as soon as you have code.


Generally speaking, Linux tooling support is pretty great these days. I'm running Debian Stable on a Macbook Pro (MBP) and couldn't be happier. Most things just work as expected.

Apart from a few tiny things here and there. One of them is the ability to adjust brightness. The standard way for many window managers (WM) is to defer that functionality to xbacklight. However, this doesn't work on the MBP.


AWS S3 has a great, but little known functionality: You can request metadata about the content of the bucket in XML. This makes it a great storage space for all kinds of batch oriented applications. No need for a self-written API.

Requesting the metadata is easy, it's just a GET request to the root of the buckets' URL: http://[bucket_name].s3.amazonaws.com/

The response will look like this:


Redux is a popular choice when it comes to dealing with state in larger single page applications. But even smaller applications might benefit from a redux architecture. I will show you how to implement redux in less than 30 lines of ClojureScript to get a clean application structure and to reduce cognitive load.
