There's not enough "fuck you"s in the world to react to this shit. should be tools used in the service of people; what in the world is this proposal to make people work for LLMs?!

Any and all changes to scientific publishing needs to be for so that other people can access them and understand them.

And the single most important change would be for Nature and other publishers not to charge 29.99 USD for a shitty 4-paragraph essay that they didn't pay for themselves.

Yey! Our grant to implement support for internationalisation of help pages in #RStats was accepted! 🎉 💃

We need to burn Elsevier to the ground. And since we have a fire going, throw the other big publishers for good measure.

I need to update my "Why I love data.table" blogpost using the new native pipe syntax. With the new _ placeholder, now you can pipe #RDataTable with

dt |>   
 _[, do_stuff(column), by = group] |>   
 _[, do_smth_else(othr_col), by = othr_grp]

I've just learned that Doom on the SNES used precomputed lookup tables to compute trigonometry functions because the processor was to weak to compute them in real time. I wonder if modern games couldn't use that trick to eek out a bit more performance.

eliocamp,
@eliocamp@mastodon.social avatar

@BeAware Yeah, I would think that. On the other hand, modern videogames also perform a lot more trigonometry computations so even a small speed-up might get you a couple of extra FPS. Or maybe there are more complex computations that could be cached!

If anyone asks me why I chose to move to Australia to do a postdoc, I'm going to answer that it's the only country with the same electrical plug that Argentina.

First working prototype of multilingual help support in #RStats. A help_i18n() function that takes a topic and a language and opens up the help page of that topic and any installed translations in that language.

Translations are regular packages with the translated documentation but no exports.

Again I have to ask, what are ~USD 3 000 that Frontiers in Cell and Developmental Biology charges for publishing being used for if they can publish such utter nonsense.

What should be the response to an author submitting such an obviously nonsensical figures, the editor accepting, and the reviewers who let it pass? (Also, read the quote by one of the reviewers, who basically said that it wasn't his responsibility to check the figures).

Figure with a nonsensical diagram with arrows going everywhere and multiple nodes labelled "JAK". The caption starts "Diagram of the JAK-STAT signaling pathway.
Bizarre drawing of a rat with a dissected penis whichis twice its body in size and is labelled with nonsensical text such as Dissiliced, sentollcstem cells, and dck. THe caption of the figure reads "Spermatogonial stem cells, isolated, purified and cultured from rat testes"

This is soo cool! Work in progress, but still!

#RStats

Video de RStudio. El comando help("mean") muestra la ayuda de la función mean en inglés. Luego, library(rhelpi18n) y Sys.setenv(LANGUAGE = "es") y help("mean") muestra la ayuda de la función mean, pero en español

Say I have a bunch of subway stations. Some of them are connected by more than one subway line. Is there a way of plotting a scale like this with #ggplot2? Stations connected by just one line drawn in that line's colour, stations connected with more than one line, drawn with alternating colours.

Today I learned about fir waves. When a tal tree dies due to wind exposure, it exposes downwind trees to the wind, with also are more likely to die. Small trees start to grow in its place that are protected by the wind by their neighbours until they are tall enough to be affected. These waves travel downwind at between 1 and 3 meters per year.

I took historic pictures from google earth to make this gif. Notice the rows of taller trees "propagating" north.

A gif of many satellite photos of a forest. There are many lines of lighter trees that move north.

I've been thinking about that Sabine Hossenfelder video* that is doing the rounds and I have to say that I mostly don't like it. It raises real issues with how the incentives are laid out in science, yes, but the whole framing is (sometimes explicitly) that that is all academia is and there's nothing of value. Besides, these are not new issues and a lot of people have been talking about these points in a much more productive way.

But most science is fumbling around in the dark trying to answer small questions based on the established theories. And I'd dare to say that most of that work ends up nowhere, which is also important knowledge ("we tried this and it didn't work" is honest work). And that is not bullshit. It's not glamorous, but it's not bullshit

The thing that shocked me when I arrived in is that the vast majority of this gigantic city is suburbs of one floor houses or duplex at the most. It's so low density compared with . I found this website with an interactive population density map that confirms just how sparsely populated this city actually is.

Similar plot for Melbourn. Most ares are light blue and most people live in areas with 2000 people per squared kilometre and almost no one lives in ares with more tan 10000 people per squared kilometre. The population weighted density in 2020 is almost 3700 people per squared kilometre and the peak population density is 16900 people per squared kilometre.

@streetsaliveyarra nice! This shows the Melbourne's dynamic even more starkly. A tiny packed city centre with skyscrapers immediately surrounded by a vast sea of single-floor housing with almost no middle ground.

Good time to remind (especially folks new to R) #RStats folk that R is (in part) directly powered by Fortran https://github.com/search?q=repo:wch/r-source%20language:fortran&type=code

@hrbrmstr And also remind anyone that checks out the weather forecast that most weather (and climate) models are written in Fortran too.
