Articles about howto

  1. 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.

  2. Adding text or graphics to a PDF file

    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.

  3. 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.

  4. Checking links with linklint

    This website contains lots of external links. A fact of life is that hyperlinks are subject to change, so they need checking every now and then.

    In this how-to article I’ll cover how I did that for this website.

  5. Making a subset of a git repository

    Since I am in the process of making most of my programs available on github, I have been re-shuffling the some git repositories. Especially my collection of scripts (small programs for different purposes). Because some of those scripts are private, I don’t want to publish that repository as a whole.
