I created one of those “awesome lists” for K-samsök resources, I have personally found awesome lists useful when starting with something new our just needs to investigate useful components a hobby project. Therefor I decided that it might help someone else to have one list for all the best K-samsök projects and resources so that people might get started quicker with one of Europe’s largest Linked Open Data platforms for heritage data.

I sometimes write code to learn things not at all related to code or technical concepts. It can be an implementation of a concept in math or even a
Resting Metabolic Rate calculator. I used this technique quite a lot back when I was in school.
Below I’m providing an example I found while looking through old hard drives during the holidays. It’s Python implementation of the basics of complex numbers. The implementation itself is useless as these features are already built into the Python standard library itself but at the time things like this helped me grasp concepts quickly.

Implementation of Polar and Cartesian coordinates and conversion between them.
These features exists within the Python standard library, this was meant
for educational purposes.
def __init__(self, real, imaginary, polar = False):
distance = real
angle = imaginary
self.real = distance * math.cos(math.radians(angle))
self.imaginary = distance * math.sin(math.radians(angle))
self.real = real
self.imaginary = imaginary
return math.sqrt((self.real ** 2) + (self.imaginary ** 2))
multiplier = 1
if (self.real < 0):
# Quadrant 2 or 3
multiplier = 180
elif (self.real >= 0 and self.imaginary < 0):
# Quadrant 4
multiplier = 360
return math.degrees(math.atan(self.imaginary / self.real)) * multiplier
Click the link or type runes.rocks into your web browser and you will be directed to a random article about a rune inscription or runestone.
I love small ideas and experiments. They are cheap they scale from a few hours to a few moths. An example I’m often refer to is Kyrksok.se a site we build a few years ago in less then two days.
However runes.rocks and the Swedish version runor.rocks sets a new record. It took me five minutes to buy the domain names and everything up thanks to existing tools.
I bought domain names and pointed the redirect URL to Magnus Manske’s Random article tool and waited for the name servers to update. Done.

There are multiple “On this Day” APIs built on top of Wikipedia but I created yet another one. This API can be used to retrieve birth, deaths, and events for any given day of the year.
The reason for building this was that I wanted something stable with support for things like Cross-Origin-Requests and SSL. The need wasn’t actually mine. A friend of mine sees the potential of “On this Day” information as a possible delighter in everyday contexts and I offered to help.
