About me - Personally

I'm a German 👨‍👩‍👦‍👦 father and 💻 computer scientist / 🧬 bioinformatician who lives in Denmark. I keep my spirits up by 🏃‍♂️ running.

I love nature, and going for hikes over valleys and hills. I'm interested in all living things and understanding how they work.

I'm interested in sustainability, and solutions to tackle the climate crisis. I'm writing software for personal management of the own co2 footprint.

About me - Professionally

I like to use software and machine learning to discover structure in unstructured data. I have a 🎓 PhD in computer science - "unsupervised learning of biomedical data".

How I try to be more sustainable

Tree donations/sponsoring

I am planning on continuously donating/sponsoring trees. That means I pay money to organizations that plant and care for trees/forests.

So far I have donated the following:

Our Electricity Plan

Recently we changed to an electricity plan at our energy provider that is 100% wind power (Energi Fyn - NaturEl).

The cost difference from our previous plan was comparably small (41 vs 37 øre/kWh), while this significantly reduces emissions.

While I disagree with calling the wind power plan emission free as Energi Fyn does (since production and maintenance for wind turbines should be incorporated into this value), average co2 emission levels of offshore wind power is denoted as 12g/kWh on Wikipedia - so are still pretty low.

Thus, assuming that Energi Fyn mostly uses offshore wind parks with a technological level causing median levels of emission, this still corresponds to a highly significant decrease in caused co2 emissions per kWh from 383g (our previous plan) to just 12g.

sorry for spamming - just wanted to copy over some of my old posts so my new wall isn't that empty 😀

Nice! That aligns very well with my perception (as a European) and gives me indeed hope about the upcoming election and that there may be more Americans coming to their senses and speaking up than I dared to hope.

This'll leave mark.

National Security - Defending Democracy Together

... we believe Joe Biden has the character, experience, and temperament to lead this nation. We believe he will restore the dignity of the presidency, bring Americans together, reassert America’s role as a global leader, and inspire our nation to live up to its ideals.

While some of us hold policy positions that differ from those of Joe Biden and his party, the time to debate those policy differences will come later. For now, it is imperative that we stop Trump’s assault on our nation’s values and institutions and reinstate the moral foundations of our democracy.

Earlier I loved hot sunny days and enjoyed going out for hikes and runs to really exhaust myself. Now they are just # me and make me think about the dire future we are most likely facing.

Sept. 14, 2020, 8:36 p.m.

Totally agree. These developments have just as much and more reason to make the headlines as others such as Covid 19 do.

The period 1July 2019 - 30June 2020 was the warmest 12 months ever recorded. Wildfires, floods, storms, droughts, melting permafrost, locust swarms, historic heatwaves. And now glaciers are literally collapsing in front of our eyes.
When will we start treating this as a crisis?

Is there a # similarly to the #?

Once in a while I'm playing around with my Google Nexus 10 from 2012 and do think that it feels quite nice to sit with a # instead of a laptop - it's just so old and slow and insecure by now that it's annoying me every time.

I don't really want to buy something though that needs to be thrown out again as soon as its battery gives up or any other part for that matter. I'd like something that can be # and doesn't have a huge # #. Does something like that exist? As an additional bonus I'd like if its hardware was open source friendly if you can call it that, such that chances are high that lineageos and Linux kernel can be installed and maintained for it relatively hassle free.

Any recommendations?

So-called ”climate denialism” is no longer the problem.
But rather the general ignoring and belittling of the climate emergency. As this sends signals that the situation is under control and real action is being taken - while the crucial 1.5-2°C goals are slipping out of reach.

Sept. 14, 2020, 8:32 p.m.

"Wir müssen also davon ausgehen, dass alle Ideen zur technologischen Abwendung des Klimawandels, die heute entwickelt werden, erst weit nach 2050 zu ernsthaftem Einsatz kommen können - vorausgesetzt, dass der Klimawandel selbst uns bis dahin nicht schon ernsthaft in den Möglichkeiten zur Technologieentwicklung beschränkt."

=> Nicht auf rettende Technologien warten, sondern Bäume pflanzen

"Einen deutlichen Effekt zur Reduktion des CO2 in der Atmosphäre könnte man auch erreichen, wenn die Menschen beginnen würden, weltweit in großer Zahl Bäume anzupflanzen. Etwa eine Milliarde Hektar Wald müssten weltweit angepflanzt werden"° #

cool. will try this out soon. sounds like a useful tool to complement my contributions directly on openstreetmap.org when on-the-go.

I just can't get over how great StreetComplete is. It looks fantastic, is incredibly easy to use, and actually makes it fun to contribute data about the Real World for the benefit of everyone.

If you run Android, be sure to give it a try: https://github.com/westnordost/StreetComplete#download # #

Awesome! I love the # on PC - excited to see whether this # turns out equally well. I definitely feel the story/setting has great potential for a boardgame.

Attributes I thought I had, parenthood proved me wrong
Sept. 14, 2020, 8:01 p.m.

An excerpt of attributes I was convinced I had, where parenthood proved me wrong:

  • patient

  • calm

  • flexible

  • consequent

  • convincing

  • clear at communicating
    ... (There are for sure more)

I see more and more clearly that these attributes i believed to have were mere wishes of how I would like to be. I was always striving to achieve these, but parenthood made it impossible to pretend that I had fully succeeded.

I feel parenthood teaches me something new about myself and others each day. I...

Filtering CO2 out of the atmosphere?
Aug. 23, 2020, 6:55 p.m.

Recently something got me thinking: Could we filter out co2 from the atmosphere and somehow transform it into something solid to keep it out of there?

But then again: would this help us in any way or wouldn't it probably just make us even more lazy and unambitious in solving the core problem - the production and emission of co2?

Also, I read frequently that technological solutions can't help us out of the situation technology got us into in the first place.

But I'm still sceptical. Really...

Respect for The US of A? Less and less.
Aug. 19, 2020, 8:15 p.m.

5 years ago I had a lot of respect for the USA and Americans. I felt that they positively contributed to humankind - my view was mostly based on impressive research they did as this is the area I was coming from.

I guess about 2 years ago I realized that I was surprised and shocked that Americans decided to choose someone as their leader that would directly contradict anything I had so far believed the USA to be: tolerant, eloquent, educated, honest, reliable. I was mad at Trump for being so...

powerless against the climate crisis?!
Aug. 8, 2020, 8:29 p.m.

My guess is that 95% of all people that accept that the #climate #crisis is real and rolling onto us feel as #powerless about it as me:

What can I achieve?

With just a handful of friends, close to no audience, with weekdays so fully packed, when at home constantly occupied by the family.

Seriously, what can I do? I'm really trying, using my education (computer scientist) to trying to make software that can make a change, but I feel no resonance. And definitely not enough impact to achieve...

Anfänger-Leitfaden für das Fediverse
July 26, 2020, 7:10 p.m.

Hier hab ich mal ein paar Sätze aufgeschrieben für all diejenigen, die ich davon überzeugen möchte, in das freie, verteilte, dezentrale soziale Netzwerk "Fediverse" umzuziehen und die monetarisierten und zentralisierten sozialen Netzwerke wie Facebook und Co. hinter sich zu lassen.

Ich werde diesen Leitfaden immer mal wieder aktualisieren, wenn mir neue wichtige Details einfallen. Platzhalter in [] an verschiedenen Stellen signalisieren, dass ich...

CO2 Footprinting - Progress and Insights: Transportation and Food Overshadow Everything Else
July 2, 2020, 7:12 p.m.

[cont. from Software Framework for CO2 Footprinting and co2 tracker: some progress]

My CO2 footprinting app in its current state allows me to model the things I do everyday and annotate my "events" with emitted CO2.

So one could say I advanced from the development stage to a data curation stage. Because what I have to do now is mostly to look up the emission data of the everyday...

streb' danach
June 25, 2020, 9:19 p.m.

Streb' danach
Wie sie auch damals schon alle taten
In letzter und vorletzter Generation
Nach der Erfüllung.

Tu' was dir jetzt wichtig ist.
Denn in 50 Jahren wird dein Kind sitzen
Und deine Taten hinterfragen bei leuchtenden Dias.

Was sie alle aus Überzeugung taten
Ohne dass ich es sah und wusste.
Was tu' ich, das meiner ebenso authentisch ist?
Alsdass in 50 Jahren meine Kinder sitzen und finden, ja das macht Sinn.

Und so wird dein Kind nicht das selbe
So wie du vor 50 Jahren tun.
Doch das...

Photoprism Sponsoring
June 7, 2020, 10:29 p.m.

I have been looking for a photo management software for a long time, that allows me to manage our pictures, host and share them, provides a sleek UI, and has some cool features that make my life easier.

For quite some time (and still), I am using Nextcloud to do this, but I always disliked its inferior performance due to PHP. Recently, they also completely replaced their pictures app by a new one, which, apart from the fact that the app seems far from feature-complete and polished to me, made...

co2 tracker: some progress
May 22, 2020, 1:44 p.m.

[cont. from Software Framework for CO2 Footprinting]

I've been coding on my #co2 #emission #tracker project for about a month now and there has been some (limited) progress, that my (limited) available time would allow.

First of all, I feel very positive about what level of insight and awareness the project could already give me despite the early stage it is in.

I've started by evaluating some web frameworks' facilities for quick...

Nachdem wir hier in einem ländlicheren, stark landwirtschaftlich genutzten Vorstadtgebiet auf Jütland im Winter fast nur Krähen und Elstern zu Besuch hatten, sehe ich in letzter Zeit erfreulicherweise auch einige kleinere Vögel, zB. Bachstelzen.
