I was working on a study and while doing so, I updated all my R packages. To my surprise, this changed the results in my analysis to a degree that it caused a change in the conclusion. I suspected it was due to an update in the psych package. The update notes read: Bug fixed […]

This is just a brief post summarizing some stuff because I don’t have time to do more right now. Noah Carl asks me: Can you point me to some evidence (e.g., a blog post) on “PC-bias” in polling in recent years? It is hard to establish biased polling. One has to: Obtain datasets of polling […]

This book is written by one of the persons behind Skeptical Science, a website debunking pseudoscience in the area of climatology and global warning, very much like Talk Origins debunks evolution related pseudoscience. The book itself has more of a meta style and does not cover all arguments put forward by climate contrarians. After all, […]


I wrote about this before, but since this is a frequent problem and my last post wasn’t brief, here’s a shorter version. The primary way to install software in Linux is to rely on apt-get (apt in Mint) or some other package manager. The way this works is that there is a central server which […]

I’ve decided to re-do my old and not too well done 2013 study. It goes like this, for multiparty democracies: Countries differ in the number of houses: 1 vs. 2. Countries differ in the number of seats in these houses. Usually, to get a party on the ballot, one must first collect X signatures. This […]

Syncthing is a open source synchronization application. It’s a replacement for the closed source Bittorrent Sync (BTS).  If you are currently using BTS, I recommend switching because 1) it’s closed sourced, and 2) owned by an American company, and thus 3) likely to implement NSA-style backdoors. This is made more likely by the fact that […]

Gwern has an old note on the US’ offer to buy Greenland from Denmark after WW2. Aside from the usual nationalist feelings about land, the Greenland population is ~25% genetically Scandinavian, presumably mostly Danish. This number is from genomic studies, the sociological counts differ somewhat because they include the mixed persons in the Inuit group […]
