Unser Pizzarezept. Auf Deutsch und mit Sauerteig. Ich habe mich aber eingelesen, das mit dem Sauerteig ist schon auch italienisch. Man nennt es dann allerdings lievito madre oder — in diesem Fall — lievito madre liquido, weil es flüssig ist.

Blog language

Posted: 4th June 2020 by knoppi in Uncategorized

Long time no seen… I actually have the impression that I do not like writing in english. So I decided, to bin the decision having this as an english blog.

This does not mean, I will write everything (the few articles I actually do) in my mother tongue (i.e. in German), but will decide from case to case.

“Hello World” in Kubernetes

A “Hello World” in Kubernetes should be very similar to one in Docker. Oh no, wait, actually, it should not.

Using containers in my eyes reaches its full potential only when combined with an orchestrator – the usual choice should be Kubernetes. But if you build your own Dockerfiles you want to have a development environment where you can test the images on that orchestrator. This environment should be set up easily and responding fast.

This ought to be some kind of tutorial on how to write your own syntax highlighting rules for vim and how to activate them. Actually, the sites I found on the web, were either too superficial or much too complicated – like the vim documentation itself. I used them all to learn the art of syntax highlighting. Still, I am no master. Anyhow, there is a bit of pride about my success.

Only a few days, since I started my new job at Heise | ix, and already at the second day my first article appeared. Fortunately, the topic was very closely related to what I did before during my PhD where I was working on graphene. Well, just follow the link to Neue Perspektive für Kohlenstoff-Transistoren (article is written in german).

Personalized City Map

Posted: 22nd June 2015 by knoppi in Computer Stuff, Linux, Software, Travelling

I was, for a long time, dreaming of a personalized map of something. Not necessarily a city map, also hiking maps were fine. At home online maps were alwas fine. Zooming in, changing map center and similar stuff went fast, I got all the information I needed. But, eventually, I desired a hard copy of something. Preferably created with an easy-to-use tool.

First try was the export option of (OSM) – currently my favourite map source. This offers map extract as bitmap images at screen resolution which usually works fine but you’re limited to the pre-rendered tiles and for a large detailed map you would have to stitch it together. They also offer export as vector graphics which is way better, but does not work for larger areas (download often breaks down). And the zoom level is defined by the map size and your screen size, basically.

Second step: ask google, I’m for sure not the first one with this problem. So I tried:

“How to create printable maps from OSM?”

“Export maps OSM print”

“Make my own map with OSM”

Actually, I’m not sure anymore about what I typed. Now these queries help, I was nearly desperate when searching. Most solutions could be summarized to using mapnik – a library which can easily be called from Python. But sometimes I’m even too lazy for Python.

The solution I found is Maperitive and – following the intention of this blog – I, here, write down my personal way of understanding why Maperitive is my solution.

Last friday, I received a long expected package. The unpacking revealed this:

Yesterday, I published an article about majordomo and my conclusion of nut using it, since the version my webhoster provides does not support archives and digest functionality. But do I need it actually?

I think that the mailing lists will have only a very limited number of users and, hence, only a small amount of traffic — digests are not neccessary.
Archiving – I will find a work around.

The only remaining question is if there are important security issues which are not avoided by my configuration. Anyone seeing a problem there, feel free to comment here!

A major domus

For several projects I recently felt the urge to dive into the world of mailing lists. Since I prefer having full control over such things rathern than delegating them somewhere, my first step was looking into my own webhosting package. It includes the the possibility to set up majordomo-mailinglists – I don’t know the exact number, it is nowhere stated, but the number email-adresses which for my package is 500, might be a limit – which, most likely, is sufficient.
My demands for a mailing list are the following ones.

  • little administration, high control
  • easy for users
  • preferably a closed list with control over external visitors
  • controllability of the mail header up to a certain degree
  • a cool unsubscribe-by-mail feature
  • an archive available

And some minor features which I’m going to explain in more detail later.

Can this be accomplished with majordomo? Are there other caveats not visible at this point?
