Often TTRPG players only write down items on their character sheet. Cards have many advantages: easier to read, you can pass them back and forth, and they are nicer to look at. The example above shows a card for Mothership , which was printed on-demand.
At one point in the software life cycle, a project becomes legacy. Then the goal is to keep its maintenance cost at a bare minimum and “only” consume security updates. But can one actually do that without also incorporating any breaking changes? My gut feeling disagrees with that. But what does the data say?
Here you can get a free skin cancer screening in Hamburg even if you are younger than 35 years.
Last month, Germany elected a new parliament. I have seen many maps (e.g. Die Zeit , Der Spiegel , this post on r/dataisbeautiful ), but I always felt that coloring the map using either a single party or using the dominant party hides the how diverse the country really is. This is why I set out to create my own version.
Last year our electricity bill was higher than expected. So I’ve decided to I need some insights into our consumption and bought a LEDVANCE Matter SMART + plug. It can connect to my Home Assistant installation using matter , the promising new standard for IoT . Since my Home Assistant setup runs self-managed on an Orange Pi 5B , I opted to install python-matter-server in a container alongside the…
Ransomware has become an increasing thread to companies. IT departments often suggest that clicking a link in a fishing mail can infect you and that it is the personal responsibility of each individual employee to not do that. I think this framing is flawed. There a many measures that an organization can and should implement that each will protect against “single click infections”. Manual checking…
I am using Linux in the form of various distributions for probably over 15 years now. After 8 years with my trusted Lenovo Thinkpad X1 Carbon, it was time for a hardware refresh. I got a framework which turned out pretty nice. I take this opportunity to also reflect on the current state of Linux on “Desktops”.

It all started with a recommendation of a friend, that was to never read The Elements of Typographic Style shortly before you have to finish something. Since then I have finished many things so it was time for insightful procrastination. I read the book and now I cannot unsee it. Bad typography – everywhere, but especially in tech. So I had to redesign this blog. After consulting The Elements of…

This is an intro into FPGA programming for Software Engineers. It uses the iCEBreaker development board and focuses on Open Source.
Fermentation is a wonderful hobby and can make your cooking experience way more interesting. Breading the right fungi and bacteria can require a certain control over the environment though. Especially temperature and humidity can be tricky to get right and a Fermentation Chamber can help here.
This is my answer to call for blogs 2020 and somewhat an update to my post from last year . You don’t need to read the old post though, since this post is written in way that it incorporates that content as well.
Some months ago, I got an email from my server provider Hetzner , telling me that I have to migrate my server to a new system. When I started with this entire server hosting as a student, I had loads of time and interest in these things, but nowadays, I just want something that is working. I do not want to care about exploding mail standards , Debian upgrades, server migrations, ever evolving…
This is my personal answer to the call for Rust 2019 Roadmap blog posts . To make it easier to read, I’ve separated the post into sections by topic.
Democracy — the great promise of freedom, sanity and happiness that westerns leaders made. It is the way we organize states, federations, unions, communities, forums, families, universities and nearly every organization where humans need to come along. We assume that it is the status quo of living together. The problem is, it is — at least in its current form — doomed to fail, and I will explain…
Nearly every service, app, website or provider we use records a bunch of data about us, for good and bad reasons. Not all of them enable you to use that data, but some of them make it pretty easy. This is my attempt to get an entertaining (and not to serious) picture of my motion profile that Google recorded for 2016.
Setting up your own email server sounds like a good idea when you are into privacy or when your boss asks you to do so. What sounds like an easy afternoon project quickly turns into a mess, even when you only have very few (or only one) mail account to manage. After trial-and-erroring for a long time, I want to give an overview over all involved technologies and possible stumbling blocks. This is…
Master thesis research – time to rant: Research paper from 1970, 11 pages, @sciencedirect still wants you to pay > $35 😶 — Marco Neumann (@crepererum) June 9, 2016 Totally unexpected, I got offered some help: We can help you do your homework perfectly.just DM us. @crepererum — customwriter (@customwriter851) June 9, 2016
During the last summer, I was working for the Invenio team. Now, after some months of pause I think I am able to talk about this piece of software with a certain amount of distance. To get to the point: I would rewrite it, and here is why and how.
This is the last part of my Interrail post series. Check out the previous parts as well ( 1 , 2 , 3 ).
This is the third part of the Interrail post series. The two previous parts ( 1 , 2 ) where about Italy and the coast of Slovenia.
This is the second part of my Interrail post series. The first one was about Venizia/Venice and Trieste and now we are continuing to Slovenia.
It was summer and because of the remaining days off which I got granted during my internship at CERN, it was time for vacations. 2 weeks. Time, which I definitely did not want to spend at one single place. So, a road trip? Mmh, without a proper car, properly not the best idea. Bus traveling? I had this one in South America and it takes too much time for only 2 weeks. So train? If so, how far? Good…
It is time for another Random Output post, this time featuring an evidence of unicorns, my flat’s garden and money problems.
Splitting software into packages and defining dependencies between them is a good thing. It simplifies security updates and enables code reusability. However, it comes with a big pack of problems, collected under the term dependency hell . All package managers have to deal with it and some of them get it right (e.g., Meteor , libsolv used by Zypper and DNF ) and many of them do not (e.g., pip ).…
This time there I do not have to tell much about the graphics. The reason for this is that my experiment turned out to be less enlightening than I hoped it would be. Anyway, it is quite a good amount of data and some people might need a new data-driven wallpaper. What you see here is a the transaction split over a day.
This is the first Random Output post. This post series will contain random material I want to share without long and complicated descriptions.
Time – the only thing we constantly pay but that cannot be charged, grown, created or constructed. It is our most important resource and because it is so important, we try to use it as efficient as possible. We are running from one place to another, hunting for the newest the hippest things, eating faster than fast, messaging in snaps of second, living never ever alone, sleeping short and clean…
Casting number 7, I’m getting old here. My flat needed a new member again so we’ve written some text, collected some detail, prepared some pictures and uploaded a nice advertisement to www.wg-gesucht.de . Like every year, they spammed my inbox, but this year, it was worse. So many homeless students. After 15 days, when the ad was on the bottom of the list, I received 98 application emails. Here is…
A binary table showing which of 24094 drugs (rows) containing which of the 4139 possible substances (columns). The color shows intensity when blurring vertically. Most common substances are marked.
It starts when you go to school and you realize, that there are some teachers who can to teach you something, and other who fail; that there are kids who like biology, mathematics, and languages, and that there are others who don’t. And that these love or hate relationship to a subject can be measured by grades, or that this is at least what they’re telling you. You slowly get the idea that…
During the restyle of brain4D I tried to style the UI more intuitive. One of the main points was to clarify which parts are active and which are not. The main approach is the variance of colors, so that the contrast of outer background, border, inner background and text is high or low.
A short (but now outdated ) overview over this server.
This week silicon valley produced the biggest deal since months. Facebook bought WhatsApp for 19 Billion US Dollar. Because it’s more difficult to buy things using stocks, let’s only talk about the 4 Billion cash. Four Billion - $4,000,000,000. Can you imagine how much money that is? Me either, so have a look at some examples. What can you do with 4 Billion USD?
Selecting a hostel, accepting a date request, bying the next car, choosing what to eat, donating to a hospital for children in Mali, sleeping longer on Sundays - all this decisions we make are based on what we expect to achieve and which personal these achievements have. Unfortunately we’re not able to know the future, so we need to guess the value of the things we get.
I grew up when music was already digital. The first form of music I really used was packed in the form of CDs. But to be honest, I’ve never bought a CD. I just found it to expensive, so I’ve got copies from friends and family members. CDs required you to prepare your playlists wisely, because getting them required time and money and they only were able to keep around 20 songs.
