i3wm And Natural Scrolling

Since I set up my little Linux box- after sticking with Mac for decades -I could manage a simple and easy setup. The only thing that drives me crazy was the lack of “natural scrolling.”

It is a pain and a shame that we still have to suffer from lousy browser implementation. But we do.

Exconfig ConfigLogger

Today I implemented the module “ConfigLogger” for Exconfig. Exconfig is a configuration cache for Elixir and can be used to read environment vars during runtime.

A Backup May Not Be Enough

First of all, I need to express my anger about the latest Apple developments. The story starts with a broken keyboard in a 2017 MacBook Pro. Apple will replace the keyboard without costs, but they will take it for two to four weeks. So, I found one of my old MacBooks (2011) will do an excellent job for this time. Only, there was MacOS Sierra, not even High Sierra installed. And with Sierra, I can’t run all of the application I use on my 2017 MacBook. Ok, I started to update to at least High Sierra which crashed in the middle of it because of a power outage. And then, and then, the Mac didn’t find any hard disks anymore.

Simple Environment

I’m a Un✪x shell and Vi[m] user since 1986 and after years, my environment settings become messy. I never have to clean up because I was the only one using it. … and it was so convenient.

Exconfig, A Configuration Cache For Elixir

Today, I wrote my fourth HEX-package and published it on “hex.pm”.

Make Your Integration Tests More Readable

Inspired by Kat Tornwall’s talk about integration tests with Elixir and Phoenix I did some clean up in my integration tests of my current Elixir project. Look how much more readable they are now.

Stop Writing Unused Code!

“Visual Studio is one of the single largest pieces of software in the world,” he (Chris Granger, a software developer who worked as a lead at Microsoft on Visual Studio) said. “It’s over 55 million lines of code. And one of the things that I found out in this study is more than 98 percent of it is completely irrelevant. All this work had been put into this thing, but it missed the fundamental problems that people faced.

Programmers, Do Proper Craft!

Yesterday (2018-03-20) I attended a seminar on regulations in medical software. It gave me heebie-jeebies because it’s obvious that Uncle Bob’s fears seem to become true: law and government will tell us how to do our profession. And gosh, what they are telling us is to go back 10 years. We should not be that passionate programmer and we should swap the two sides of the Agile Manifesto again. The right side really matters much more for them ;-(

Work’n’Life - Meetups Linz

This week I did attend the kickoff meeting of Work'n'Life (like in Rock'n'Roll) at Factory 300 in Linz. The place (Tabakfabrik Linz) is gorgeous and the talks were impressive and very informative.

Regulatory Demands

We, as software developers, will face more and more regulatory demands. Business, government, laws will tell us how to do our work.

GraphQL & Elixir

GraphQL attracts me more and more. So, I just bought the (beta) book “Craft GraphQL APIs with Elixir and Absinthe” at “The Pragmatic Bookshelf”.

Next, I will figure out how to use GraphQL at the frontend with ELM fetching data from the Elixir backend. A combination I consider to be really faaaast and clear.

What else should a programmer do on a cloudy Sunday afternoon if not fiddle around with something new? So, since I’m practicing some functional stuff a while now (Elixir, Erlang, and Phoenix-Framework) I wonder if there is a good functional oriented frontend language for the browser. And of course, there is one: ELM-LANG


Elixir/Phoenix – Module js/app not found

After updating Phoenix to 1.3.0 app.js was not loaded properly anymore. I got the error module js/app not found although js/app was loaded. e.g. confirm: "Sure?" option doesn’t work with my delete-buttons.
