Basic Emacs-keybindings for LibreOffice Writer

Although I try to avoid to use word processors like LibreOffice Writer, sometimes - mainly for collaboration purposes - I have to fall back on them. And in such hard times I want to have at least some useful keybindings. Because I couldn’t find any downloads that provide Emacs bindings for OpenOffice/LibreOffice Writer I configured the basic bindings which you can download here.

Moving from Textpattern to Hyde and integrating Orgmode

This post is about my switch from Textpattern to Hyde as my website system (some call it CMS thought).

In the past I tried a few systems, starting with Wordpress, then DokuWiki and then Textpattern. The reasons for this changes were mostly the extensibility of the systems and the way you write articles/posts etc. Until the next switch I think I’m happy with Hyde :)

Save useful time by writing presentations with Orgmode and Beamer class

I just wanted to share my happiness about a new workflow for writing presentations. I couldn’t believe how quick I got useful slides by writing my notes with Emacs’ Orgmode. So, here it is:

1. Do some research or brainstorming or whatever and take notes with Orgmode
2. Do a little cleanup on the structure of your notes so that you get a useful structure of your slides
3. Export your notes with the LaTeX Beamer class
   • You may have to append the defintion for beamer class to org-export-latex-classes. Here is my definition.

That’s it! This means you don’t waste any time with creating your slides and you can concentrate 100% on the content. I’m sure that’s (even more) faster than writing pure LaTeX and faster, nicer, … than [Open|Libre]Office/PPT anyway. Don’t know what to do with the whole time, but thanks Orgmode! :)

P.S.: Yeah, two posts below this one, I wrote about Vim – just don’t care ;)

MongoDB as RDF triple store based on Node.js

This is a short summary of my bachelor thesis that was written in German. Maybe someone else is interested in the results.

About

The topic of the thesis was “Implementing a RDF storage solution for MongoDB”. Besides this implementation part the performance of the written API was compared to Virtuoso Open-Source.

So, to summarize this thesis, the main question is “Could MongoDB be an alternative to Virtuoso as triple store?”.

vi Bindings everywhere

This should be a little overview of how to tweak some programs to use the awesome vi Bindings. I’m sure its not complete.

• Abiword
  • Put KeyBindings="viEdit" in the <Scheme name="_custom_" ...> section of your ~/.AbiSuite/AbiWord.Profile If you want to cycle through the input methods pressing F12, put KeyBindingsCycle="1" also in this section.
• bash
  • echo "set -o vi" >> ~/.bashrc
  • echo "set editing-mode vi" >> ~/.inputrc (for other readline based tools, e.g. psql)
• Chrome/Chromium
  • Vrome
  • Vimium
• Eclipse
  • eclim
  • Vrapper
• Emacs :)
  • Evil
  • Vimpulse
  • ViperMode
• Firefox
  • Pentadactyl
  • Vimperator
• irssi
  • vim_mode.pl
• zsh
  • echo "bindkey -v" >> ~/.zshrc
  • vi-keys+

Dia Shapes für Logikgatter nach IEC 60617-12 Norm

Dia ist seit einiger Zeit mein Standardprogramm wenn es um Diagramme geht. Für mein Studium brauchte ich Logikgatter nach IEC Norm, welche in Deutschland wohl Stand der Dinge wären. Da ich diese Shapes nirgends finden konnte, habe ich sie mal selber erstellt. Hier also die die entsprechenden Dateien: Download

Zum ‘Installieren’ einfach die beiden Ordner in das Verzeichnis ~/.dia/ (unter Linux) entpacken.

Und wem die Shapes nicht gefallen, hier noch die Quellgrafiken: Download
