  1. Generate random passwords

    One way of making hard to guess passwords is to take random data and encode it with base64 to make it readable. This is what I’ve done in the genpw.py script.

    This is mainly useful for passwords that you can store in a secure manner (like in an ...

  2. Keyword expansion with git

    One of the things I liked about the old rcs revision control system was that it supported keyword expansion in files. Unlike systems like rcs, cvs and subversion, the git revision control system cannot provide keyword expansion. The cause for this is that you can’t modify a file with ...

  3. vid2mkv

    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 video ...

  4. vid2mp4

    Videos with H.264 video and AAC sound im MP4 containers seem to strike a very good size performance balance. So I modified a copy of vid2mkv to use ffmpeg to create this kind of files instead.

    To speed up the processing of multiple files, this script runs the conversions ...

  5. foto4lb

    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 it.

    The foto4lb.py script shrinks the files it is given to a width of 886 pixels, and shrinks ...

  6. make-mp3

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

    You can find make-mp3.py on github. Apart from python (version 3) it requires LAME.

    Note

    The script is now compatible with both Python 2 and Python 3. But is ...

  7. gitdates

    In answer to this question on stackechange, I wrote gitdates.py (available from github). 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 when they were last committed. The current version is ...

  8. dicom2png

    This simple python 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 processing of multiple pictures, this script runs the conversions in parallel ...

  9. git-check-all

    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 whether there are uncommitted changes by running git status. If there aren’t any, it runs ...

  10. 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 ...
