Someone sent me this email: Hello Emil I was wondering if you knew about any similar papers to this one: https://www.sciencedirect.com/science/article/abs/pii/S0160289608001591 Also, what are your thoughts on mutualism (which I assume you think is false)? Does mutualism being wrong disprove gxe theories of heritability? I know it disproves the Flynn model How about these two?…

This book offers a snapshot of cutting-edge applications of mobile sensing for digital phenotyping in the field of Psychoinformatics. The respective chapters, written by authoritative researchers, cover various aspects related to the use of these technologies in…
Continue ReadingI came across this obscure study while doing some research on other matters. Yan, H., Lavoie, A., & Das, S. (2017). The Perils of Classifying Political Orientation From Text. Linked Democracy: Artificial Intelligence for Democratic Innovation, 858, 8. Political communication often takes complex linguistic forms. Understanding political ideology from text is an important methodological task…
Continue ReadingNot an endorsement of this technology or the use of it, just stating that it will happen. Given sufficient measurement precision, all humans have unique genomes and fingerprints, but also faces and voices. The first two are well known and somewhat difficult to measure. However, the last two are very easy to measure, even at…
Continue ReadingSo, Logitech software only works for Windows. Unfortunately, the sensitivity is extremely high by default, making the mouse much less useful. The extra buttons also have no function, which is annoying. So, I wanted to fix this. The mouse actually saves the setting on itself, meaning that the settings are plug-and-play-able. Meaning that my G502…
Continue ReadingI could not find someone that briefly described this problem, so I’ll just do a very quick job at doing so. I take it that this is a common observation that I was just unable to find the right term for. And yes, I appreciate the metaness of this. :) The FOSS fragmentation problem: everybody…
Continue ReadingSyncthing 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…
Continue ReadingInstalling R packages on Windows is easy: you run the install code and it always works. Not so on Linux! Here one sometimes has to install them thru apt-get (or whatever package manager) or install some missing system-level dependencies. Finding what to do can take a lot of time gooling and trial and error. So,…
Continue ReadingI’m posting this here so I can find it more easily because this is at least the third time I had to google the issue to retrace my own steps on StackOverflow to find the solution I found last time! I even found some useful comments I wanted to upvote, only to realize they were…
Continue ReadingEdit 2019 You don’t really need the below. Look at the `model.matrix()` function, which converts data frames into matrices for glmnet and similar function. Original post Sometimes you need to use a function that wants a numeric matrix as input. One such function is glmnet.cv() which performs lasso regression with cross validation, which is very…
