A quick overview on Big Data technologies for logfile analyses. I'm tired of PowerPoint and tried Haikudeck. A few more features would be nice, but it's okay for tomorrow's presentation karaoke.
A quick overview on various big data tools for analyzing technical data.

Clojure: A Gentle Introduction (Chapter 7, Part 6)

Lisp’s every operator takes a predicate and a list as input. If there is no element inhibiting the predicate, then the answer is true. Some samples in Lisp: CL-USER> (every #'numberp '(1 2 3 4 5)) T CL-USER> (every #'numberp '(1 2 3 4 5 A)) NIL CL-USER>…

The 'CIDER requires nREPL 0.2.7' Mystery

For my Clojure developments I’m using Emacs 24.4 (running on a Mac) with a cider 0.9.0snapshot, Clojure 1.6.0 and nREPL 0.2.7. Actually. When I’m starting emacs in my home directory and open a repl with M-x cider-jack-in, then I’m getting this warning:…

Clojure: Living Without The For Loop (1)

When you start learning languages like Lisp or Clojure, you are plunging into the world of functional programming. Functional programming, as Wikipedia explains, is closely linked to declarative programming, and this means the direct opposite of…

Much more interesting – and difficult – than just depicting the architectural truth in a photo is depicting the mood and meaning of this architecture. What is happening between these walls? What did this building mean to their builders and what does it…

Watch Your Parentheses - And nrepl-server Output

Situation: Emacs, cider 0.9, writing some Clojure code. Like this: x (map #(* radius (cos %1) (sin %2)) radian-s radian-t) y (map #(* radius (sin %1) (sin %2)) radian-s radian-t) z (map #(* radius (cos %) radian-t)) See the error? These three lines are…

Story
Tagline
My photo models are at least 100 years old.
Introduction
After a few turbulent years in a science job I became a software developer and system administrator. At the moment, I'm working for the IT branch of one of the bigger German insurers. 

I have some highbrow hobbies like my wife and me growing ferns and palms, calligraphy, history, and dabbling with computers and old cameras. I suppressed my desire to take photos for a long time, but I failed: photography has become my favourite waste of time. My favourite photographic subjects are plants and stones, with some emphasis on (mostly sacral) architecture.

Being in sort of a retro mood induced and fired by my wife, I'm discovering the joys of film photography for some time. And I'm still writing software.
Bragging rights
I'm pretty good at making apple pies. I was programming a supercomputer! (Okay, it was just a Mandelbrot set.) Converging lines in photos are afraid of me.
