🎉 Happy international RSE day from the Nordics!

We have got some exciting events brewing for the future, including the Nordic Basic Scientific Computing days (No BS Computing) in Otaniemi, FI, in February and the 3rd Nordic-RSE conference in Tromsø, NO in June.

An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

🇸🇪 The second Nordic-RSE in-person conference took place in Gothenburg, Sweden, at the end of May. Find out more about the event through the words of #SSIFellow @samumantha.bsky.social in this blog originally posted on the Nordic RSE website: www.software.ac.uk/blog/nordic-...

Thank you for having me! It was an exciting visit and great pleasure to talk about @coderefinery.org and @nordic-rse.bsky.social and all the discussions around training, HPC and Research Software!

Great first day!
First Minisymposium on Research Software quality showed how work done within Elixir can reach beyond life science communities via projects like @eosc-everse.bsky.social ! Can't wait to see where this is going 🤩

JOSS re-evaluated as JUFO 1 in Finland, expands its definition - Nordic RSE We bring together the community of people writing and contributing to research software from Nordic universities, research institutes, companies and other organizations to share knowledge, to organize...

It's great to see that a national research evaluation organization, the Finnish Publication Forum (JUFO), has rated @joss-openjournals.bsky.social as level 1, recognizing its scholarly value

Frankie Robertson helped make this happen, with Nordic-RSE, & wrote about it: nordic-rse.org/blog/joss-ju...

Engaging talks and a lovely crowd. So happy to have found "my people" that I get to learn so much from every day ❤️

Thanks to other organizers and all participants for making this a fantastic event!

Blog posts and some pictures will follow ✨

Really enjoyed the opening panel this morning, thank you to all the panellists for their insights!

Last call, especially for people in the area around Göteborg:

Join us on 20.+21.05.2025 for the second in-person Nordic-RSE conference to meet fellow research software enthusiasts and hear about cool tools and projects.

sometimes annoying things happen in the terminal: why doesn’t Ctrl+C quit?? why can’t I select text? these things aren’t random: different “types” of programs have different conventions for how you interact with them! here are some categories of programs & their conventions! 1. REPLs (python3, your shell) you type code, press Enter and it runs the code rules: quit with Ctrl+D (only works on an empty line) usually you have a million keyboard shortcuts for editing text usually there’s history 2. full screen “TUI”s (less, htop, ncdu, lazygit, mtr) rules: quit with q (usually) you can often navigate with arrow keys often ? will open the help to select text with the mouse, press Shift 3. noninteractive programs or slightly interactive (grep, git, sort, scp) you start it, maybe it asks you a question or two, it does stuff, and it exits rules: quit with Ctrl+C 4. wrappers (ssh, env, tmux, rlwrap, unbuffer) these wrap other terminal programs in some way rules: when the program(s) they’re wrapping exits, they exit 5. other lots of things don’t fit info these 4 categories: text editors, games, email clients, IRC clients, … rules: I avoid these unless (like with vim) I’ve made a special effort to learn the program

Looking forward to reading the outcomes!

Exclusive: the most-cited papers of the twenty-first century A Nature analysis reveals the 25 highest-cited papers published this century and explores why they are breaking records.

"But the most highly cited papers generally aren’t the most famous scientific discoveries. Rather, these works tend to describe scientific methods or software, the workhorses on which scientists depend."
