Makes sense. {rextendr} also seems to be getting good support! I just benchmarked a dummy example (sum function), and the Rust function runs slower than native R (both simply 2+2, sum(2,2) and writing a custom R function). Are there any benchmarks, or pointers for when using Rust is faster?

I need help identifying a #bumblebee! I’m in the Peruvian Andes, cloud forest near Salkantay (and Machu Picchu). We spotted this monstrously big orange bumblebee, 3-4cm long (see picture. We actually spotted them twice, but only managed to photo once). My best ID so far is Bombus dahlbomii, but…

Sounds like my UK experience. For the oral exams in Denmark it’s never teaching assistants here either. Sometimes postdocs though. I really like a combination of the two, reminds me of this comic. I was always rubbish it written exams, but loved oral exams.

A picture of a bird, a monkey, an elephant, a gold fish, a seal and a dog taking an exam. The examiner, a human, says “For a fair selection everybody has to take the same exam… please climb that tree”.

Any folks needing to make a new CV? 📝 I've made a pretty, customisable Typst template that let's you write all your information in YAML, offers many different section layouts and allows a great deal of customisation. typst.app/universe/pac...

A fictional CV for a person named John Doe who is a data scientist. The CV is an example made with the *academicv* Typst template, showcasing some of the features of the template.

Here's an example of how it helped me literally *right now*. First example without a random slope; it's clear from the CIs that they are shared. I (of course) had to include `activity_measure` as a random slope, and tbh I'd have never thought twice about it without the visualisation reality check.

Orbital by Samantha Harvey is one of the most hauntingly beautiful books I have ever read. It captures the grandeur of everything and nothing, the beauty in the mundane, the personal experience of living, the scale and perspective of time and space. I cannot recommend this book enough!
