Omg. WTF is Happening? @lalahaenzy.bsky.social · 05/02/2026
Sir Ian McKellen performing a monologue from Shakespeare’s Sir Thomas More on the Stephen Colbert show. Never have I heard this monologue performed with such a keen sense of prescience. Nor have I ever been in this exact historical moment.TY Sir Ian, for reaching us once again. #Pinks #ProudBlue

Valid point! My intention was that they will all be dynamic, so I made the template accordingly, but as you say if it's live people will assume it's broken.. Thanks!

If you have any rec on how to set the scaling independent on device I would be grateful!

Thanks! It's my first one (finnicky af) so it is still under dev. Not all tabs are responsive (yet) and I'm wrestling a bit with restrictions on free tier shiny and huge data set hehe. Will be setting up a repo for this for sure, I appreciate it!

Made a small app where you can explore aspects of what influences dark matter research: which dark matter models have a high impact, which authors impact discourse on which models, citation network with arXiv classification, et.c. I like it as a prototype: simonallzen.shinyapps.io/shiny/ #PhilSci

Without tidyverse, I would not have been able to implement data science in my research given that i had to learn it myself. Hadley is the goat

Ny rapport om högskolornas budget: Det statliga "produktivitetsavdraget" innebär effektiviseringskrav på 1-2 % av budgeten/år. Idag har högskolorna 40 % mindre resurser per elev än för 30 år sedan, vilket minskat den lärarledda undervisningen drastiskt. tankesmedjanbalans.se/ny-rapport-o...

Om detta är ”enorm förstörelse” så har vi nog inga meningsfulla beskrivningar kvar för Gaza.

Detta system är alive and well i Nederländerna och kallas kraamsorg! Vi skulle få hjälp med hushållet men pga störda gick vi upp tidigt och städade och bakade bröd för att någon skulle komma hem till oss.

During the process of writing a paper featuring data on the global funding for Dark Matter research, and thought I could make inforgraphics of it as well. Here for North American funding.

Earlier this week, I gave the inaugural talk for the Utrecht philosophy of astrophysics and cosmology colloquium. It’s a great time for #philsci in The Netherlands, and I’m excited about what’s coming!
