Take Screenshots Straight into Org Files in Emacs on Win10

Apr 4, 2023

Update, 2023-04-05: By popular demand, I updated the below solution to include a second function which stores the screenshots in a subfolder. The Final Result Let me start this article by showing you my usage of the functionality described. I work as a Data Scientist and use org-mode in Emacs for a large number of every day tasks. One of them is the documentation of new findings within datasets or other software's documentation or websites etc.

Don't forget to sharpen your axe

Jul 7, 2022

A wise man once said… Give me six hours to chop down a tree and I will spend the first four sharpening the axe. Abraham Lincoln In this statement there is a lot of truth. For instance, it is closely mimicked by on of one of the 7 habits of highly effective people by Stephen Covey. Obviously, it applies to writing software as well, as a sharpened “developer’s axe” means:

Writing DIN-Norm (German) Letters in Emacs

Jul 7, 2022

TL;DR This post explains how to set up emacs so that the writing and sending of letters is always just a whim away. The resulting letters will adhere to the German DIN 5008 standard, and fit neatly into envelopes designed on that standard, as shown in the cover image on the top. Prerequisites All you for the implementation shown in this tutorial is Emacs with org-mode and a LaTeX installation with the dinbrief.

Umfragewerte oder Medienpräsenz: Was kommt zuerst?

Oct 10, 2021

Einleitung und Fragestellung In den letzten Jahren1 konnten in diversen Ländern der Aufstieg populistischer Phänomene beobachtet werden: der Aufstieg der AfD in Deutschland, die seit ihrer Gründung binnen 5 Jahren in sämtlichen deutschen Landtagen, dem Bundestag und dem europäischen Parlament vertreten ist; der Wahlsieg Donald J. Trumps in den USA; der Aufstieg der Lega in Italien und viele weitere Beispiele. Ein Verlaufsmuster, das bei jedem einzelnen dieser Aufstiege in der Öffentlichkeit auftritt ist das folgende Ping-Pong-Spiel zwischen Medien und Umfragewerten: Je größer die gesellschaftliche Bekanntheit, desto größer das Medienecho, desto größer die Bekanntheit, etc.

De-Googling the Blog (and my life)

Nov 11, 2020

Today, just a short notification concerning the use of analytics on this blog: I have decided to get rid of the Google Analytic Tag on these pages. It was very joyful to know how many people surfed to my little blog from all over the world, yet it doesn't outweigh my reservation against Google obtaining entry into almost each and every single piece of software surrounding us. Asides from on-site analytic tags I have recently decided to circumvent Google and its services as well as possible in my personal digital footprint as well.

Supplement to 'Nonparametric estimation of the service time distribution in discrete-time queueing networks'

Jan 1, 2020

Great news: a scientific article I have co-authored has been accepted for publication and can now be found online here or via the DOI 10.1016/j.spa.2020.01.011. Yes, my list of publications has been amended 1. This article has been through quite a lengthy review process, and was the main motivation for another one of my blog posts. This post dates to September 2018, yet I only started working on these simulations in the framework of the second round of peer review.

Calculating the Required Sample Size for a Binomial Test in R

Jan 1, 2020

A Standard Problem: Determining Sample Size Recently, I was tasked with a straightforward question: "In an A/B test setting, how many samples do I have to collect in order to obtain significant results?" As ususal in statistics, the answer is not quite as straightforward as the question, and it depends quite a bit on the framework. In this case, the A/B test was supposed to test whether the effect of a treatment on the success rate p had the assumed size e.

New Feature on the Blog: Publication List

Sep 9, 2019

On this page I have collected the bibliographic details of all the articles I have written, mainly of scientific (i.e. statistical) nature. I have written almost all of the scientific papers while under contract at a public university, either in Darmstadt or in Heidelberg. I have submitted all papers to journals which are edited and refereed by other scientists in presumably public institutions. Yet, for some reason, the results of the publically funded, publically relevant1 research is NOT officially publically available.
