My new approach to online privacy

4th July 2019

I have for the last few yeas had a online privacy approach in the style of “Do not put all eggs in the same basket” or exemplified in the style of “If I use Google for email I won’t use it for browsing the web”.

Now after a few years of empirical learning I have decided to change this approach. It’s clear that the owner of “my” online data (the irony) is seldom static nor does it keep the data within its own walls.

My new approach is to create as little online data as possible. Below are some actual examples of things that has lead me towards this decision.

There are probably plenty of cases were these types of issues have been combined and exposed information about me to third parties unknown to me.

What I’m doing to limit online data about me

One might see me as paranoid or a privacy geek but these actions comes from actual concerns and real world examples.

An Awesome List

9th February 2019

sceenshot of list contents

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.

Grasping Concepts through Implementations

25th January 2019

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.

import math

Implementation of Polar and Cartesian coordinates and conversion between them.

These features exists within the Python standard library, this was meant 
for educational purposes.

class ComplexNumber:
    def __init__(self, real, imaginary, polar = False):
        if polar:
            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

    def distance(self):
        return math.sqrt((self.real ** 2) + (self.imaginary ** 2))
    def angle(self):
        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

A Five Minute Hack

19th December 2018

Click the link or type 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 a site we build a few years ago in less then two days.

However and the Swedish version 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.
