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.
On 2016-08-12 I visited the Thermenmuseum in Heerlen.
This museum is built around the remains of a Roman bath in what was then called the vicus of Coriovallum, which is situated at the intersection of two Roman roads, the Via Belgica and the road between Aquae Granni (Aachen) and Colonia Ulpia Trajana (Xanten).
Since the previous article [1] I’ve updated TexLive to 2016. This comes with asymptote 2.38, but not with …
If you would look over my github repositories, you’ll see that most of my programs are pretty small. And in general they are command-line applications. And that is good, because small is beautiful and simplicity is a virtue.
With Python it is relatively easy to make programs go faster by running things in parallel on multiple cores. This article shows you how.
We sill concentrate on a type of problem that is easy to parallelize.
Since its inception in 2014, I’ve been following the LibreSSL project.
The OpenSSL codebase turns out to have severe problems. See the presentation, and especially sheet 7.
The version in the FreeBSD base system is old, but the version used by the ports I can control. It took a while, but now was the time for me to switch.
This article is a write-up of what I learned trying to extract information from
ms-office xlsx files using Python.
Inspired by this blog post by Julia Evans, I set up a quick way to find files in my home directory. This howto is based on FreeBSD, but should work (with some tweaking maybe) on Linux and OS-X as well.
in a previous article we saw how a desktop scanner can be used for macro photography. Often it would be handy to include a visual reference of the scale of such pictures. In this howto I’m using asymptote to add accurate scales next to the picture.
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.
