ktrask··on Migrating to Positron, a next-generation data science IDE for Python and R
I hope positron works out fine, last time I checked it was not yet usable.

Replacing Rstudio with something more reliable would be nice, because of some major design flaws Rstudio has. A lot of the UI stuff runs also in R, so when the R kernel dies, quite often I cannot save unsaved files. So I need to copy the file content to a different text editor when that happens. I also don't understand why the LLM-Chat window is running inside the R console, and then blocks running R code. That makes it completely unusable.

ktrask··on Full Moon: Seestar S50 vs. Samsung S25
I fully agree! But at least this shot with the Seestar 50 motivates me to try to get a more sharp shot on the full moon with my telescope. Just to prove to myself that I can do that.
ktrask··on Neutron Stars Hint at Another Dimension
Yes, exactly. That is why we think the extra dimensions might be small, und the inverse square law is only violated at and below the size of the extra dimensions. This is also why we are using the Yukawa Potential to constrain that possibility, because it has a length scale and a strength of a potential deviation from the inverse square law.

ktrask··on Why does APT not use HTTPS?
At a research institute I worked for, we had a proxy server that intercepted http. The antivirus software on the proxy made it impossible to download some security updates once in a while. Fortunately it was possible to change the ubuntu URIs to https:// to use HTTPS and the broken antivirus sofwate did not intervene anymore.
ktrask··on Physics facts not always taught in school
In a closed physical system energy is conserved. For example, if you have container that has Helium on one side and Oxygen on the other. Both gases will mix, i.e. maximize entropy. Minimizing energy would mean, the gas would reach absolute zero.
