  1. Removing big files from git history

    By accident I checked 60-odd full-size photographs into the git history of my website. I shrunk them in a next commit, but the history was still there leading to a bloated .git directory. This took a lot of time when making backups. This documents how I cleaned up this mess.

  2. PDF tricks

    This article contains several useful tricks for manipulating PDF files.

    The focus of this article is on Open Source and Free software, that are available for UNIX-like operating systems. These tools are made for use on the command-line of a shell.

    Using Acrobat Reader’s ability to add text et cetera has proven unreliable for me. On multiple occasions I have lost all the text added to a PDF file. When your filling in 20-plus pages worth of permit forms this is a huge waste of time and extremely annoying.

    So I set out to find another way using the free and open-source tools I have available.

  4. Installing asymptote 2.38 in TeXLive 2016

    Since the previous article [1, 2] I’ve updated TexLive to 2016. This comes with asymptote 2.38, but not with a FreeBSD binary for it.

    My TeXLive is not installed from the FreeBSD ports tree, so I cannot use the asymptote port since it depends on the TeXLive port ...

  5. Using a scanner for macro photography

    Although you wouldn’t guess it from the contents of this blog, my day job involves the design and production of products from fiber reinforced composites. A lot of my projects fall under non-disclosure agreements, so I cannot discuss them here.

    What I can do is share some of the methods I’ve developed over the years. One of those is using a desktop scanner to make close-ups.
