1. foto4lb

   Update: The script now allows you to set the target width of the

   pictures using the -w command-line argument.

   Photos from modern digital cameras are generally so large these days that you have to shrink them to use them in a document. I do this a lot, so I automated ...

2. make-mp3

   After writing the make-flac python script, I adapted a copy to use LAME to generate variable bitrate MP3 files instead.

3. gitdates

   Update: The checkfor function was split off into its own

   (included) module.

   In answer to this question on stackechange, I wrote gitdates.py. If it is called from a directory that is under git resivion control, it lists all the files there with the short hashtag and the date from ...

4. dicom2png

   Update: The checkfor function was split off into its own

   (included) module.

   This simple script uses ImageMagick to convert DICOM images from a Philips digital X-ray machine to PNG format. It crops the images from 2048x2048 pixels to 1574x2048 pixels, the actual size of the detector.

   To speed up the ...

5. git-check-all

   Update: The checkfor function was split off into its own

   (included) module.

   This scripts looks for all directories in the users' home directory that are managed by the git revision control system (i.e. that have a .git subdirectory).

   For each of those directories it checks wether there are uncommitted ...

6. make-flac

   In this day and age I want to have my music collection available on my computer. Lugging around all my CDs is unpractical and storage is relatively cheap. So I've used FLAC to convert them all to high-quality music files.

   The make-flac python script is what I use to ...

7. markphotos

   Update: The checkfor function was split off into its own

   (included) module.

   Update: use the platform-neutral os.devnull instead of the /dev/null device that is generally only found on UNIX-like platforms.

   The markphotos.zip script adds a copyright notice to pictures. It uses exiftool. This is not a visible ...

8. tifftopdf

   It is not uncommon for legacy 2D drawings to be scanned and then distributed as black/white TIFF files. While these files are relatively compact, viewing them can be a PITA. The previewer on windows XP (which is what we use at work) is slow. PDF files are much easier ...

9. avi2mkv

   My digital camera can also produce movies, like most camera's these days. It saves them in AVI format, with relatively poor mjpeg compression and uncompressed sound.

   So I wrote this python script to convert these AVI files to Theora / Vorbis streams in a matroška container. It takes the AVI ...

10. mkhistory

    Formatting git changelogs for LaTeX

    Most of the things I write, be it software or something else, are under revision control with git. Mostly because it makes undoing mistakes easy. My LaTeX documents are no exception. With software it is customary to have a change-log (like the one generated by ...
