🎉 JOSS turns 10 today! Ten years, 3,500+ papers, 11,000+ authors, 4000+ reviewers, and a community that built something remarkable together. Thank you to everyone who's reviewed, edited, authored, or cheered us on along the way 💚 joss.theoj.org #openscience #opensource

Last week, I gave a keynote at appliedml.us/2026/ on machine learning and engineering. Like a lot of us, I've had questions and anxiety around software development today. The talk covers why good engineering is still important (and 🌷). vickiboykis.com/2026/04/20/b...

"The system has been successfully upgraded" Today, for the first time in years, I read this as a user. "uh-oh."

This week on Counting Stuff, how I approach reviewing other people's code and work! tl;dr the point is to make stuff that's already going out be slightly better as it leaves the door, not be a gatekeeping jerk #dataBS www.counting-stuff.com/code-review-...

alright tanglers, it's back to shipping 🛳️ 🌐 Tangled Sites is here: serve websites straight from your repo. grab your `tngl.io` domain at tangled.org/settings/sites. already have a `tngl.sh` handle? that's your domain—ready to go! 📄 docs.tangled.org/hosting-webs...

Few days before @coderefinery.org workshop, Spring 2026! This year, on top of the usual hands-on teaching of git, GitHub, reproducibility, good coding practices we have something new: "Responsible Use of Generative AI in Assisted Coding"! The workshop is 100% free and happens entirely via TwitchTV

I enjoyed reading "An introduction to Kubernetes" by @jeremyjordan.me. The blog post is not new but it is still excellent. The intro gave me just the right level of detail and overview.

As a connoisseur of online color tools, it’s such a delight to discover a new funky take on the palette generator experience. I love the Teenage Engineering / Dieter Rams aesthetic here colorpalette.pro

I had some fun pulling OpenAI's mission statement out of their IRS tax filings from 2016 to 2024, loading them into a git repo with fake commit dates and then taking a look at the diffs simonwillison.net/2026/Feb/13/...

TIL that SQLite has R-trees: www.sqlite.org/rtree.html This means that I can have a lightweight and portable "mini-PostGIS" database all in one file for super fast range queries that I can take with me to any other computer.

Here is what I've been doing this past week: git.olaren.dev/Olaren/mapto... A little python program that generates poster for cities! You might have seen stuff like this around lately, but I modified it to put an emphasis on rail infrastructure :3

🎄 ANNOUNCEMENT: R Package Development Advent Calendar 2025! 🎄 Starting December 1st, I'm launching a 25-day journey through modern R package development. here's why you should follow along 🧵 #rstats #RPackageAdvent2025 #OpenSource

Diátaxis is an amazing resource that I recommend to everyone writing documentation or tutorials: diataxis.fr I find myself returning to it every few weeks, and each time I learn something new. #documentation

A bug in my code produced a psychedelic map. This was supposed to look very different but I liked the result. #dataviz

1st episode of 2025 winter season of #code4thought: radovan.xyz, Richard & samumantha.bsky.social explain how the coderefinery.org helps researchers get up to speed with the digital/software skills they all need. Out not on your podcast app, YouTube podcast and codeforthought.buzzsprout.com

Today I watched "The Big OOPs: Anatomy of a Thirty-Five Year Mistake" [C. Muratori] - amazing presentation and a carefully researched history lesson about OOP, about where the core ideas came from and where some really good ideas got lost: www.computerenhance.com/p/the-big-oo...

Looking back at years of doing web development with a tiny browser console log window and complaining about it until I learned that I can configure it to use a separate window.

It is such a joy to browse the amazing interactive articles by Bartosz Ciechanowski - like this one (but there is so much more!): ciechanow.ski/mechanical-w...

💡 TIL that G. Voronyi (of Voronoi diagrams) was the doctoral advisor of B. N. Delaunay (Delaunay triangulation) and W. Sierpiński (Sierpiński fractals).

Trying out my first Windows installation in this century - what did I miss?

We at NSF Unidata are pleased to announce that we have now received funding from the National Science Foundation (NSF) for the next year of our five-year award. This allows us to end the current furlough of our staff and resume our operations. buff.ly/GafcZts

Due to the current gap in funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program is pausing most operations effective 12 May 2025. Nearly all staff will be furloughed until funds from our existing NSF grant become available. For more information, see buff.ly/d2TC1Oy

US-RSE is here! 🎉 @us-rse.bsky.social

I wrote about how I interface #Fortran and #rustlang: radovan.xyz/blog/fortran...

Having fun typing a blog post about how to call #rustlang from #Fortran. It's all about choosing the right tools.

🧵 10 Simple Rules for Leadership Without Formal Authority A resource to use when you're leading and growing teams you don't have formal authority over. Full resoruce at: eoss-om-communitycalls.github.io/2024-08-27-1... y también en Español eoss-om-communitycalls.github.io/2024-08-27-1...

This amazing space is recharging and inspiring like a visit to a museum or an art exhibition.

Big news: we are setting up a new non-profit organization to run bioRxiv and medRxiv. It's called openRxiv [no it's not a new preprint server; it's dedicated organization to oversee the servers] openrxiv.org 1/n

Typst is such a pleasure to work with: the usability, the documentation, the Typst Universe, the Open Source - thank you!

I've been collecting guidance, documents, examples for open-source software projects, such as on governance, code of conduct, licenses, etc. in github.com/corsa-center.... Now I would like to add sustainability plans. What projects have good plans? Or even guides about how to write one.

⚒️ CodeRefinery free online workshop on tools and techniques for more reproducible research; six half-days March 25-27 and April 1-3, 2025 More info and registration: coderefinery.github.io/2025-03-25-w... #RSEng #FAIR #researchsoftware #git

Thank you for this brilliant episode! It really brought hope and clarity into these dark ages.

When assisting researchers with #HPC computing and programming, 90% of my effort is spent on reproducing the problem, and only 10% on finding a solution. I used to motivate #reproducibility with "it's good for others". Now: "it's good for you and allows me to help". Others benefit as side-effect.

Big thanks to #kexp for the David Lynch set yesterday! It improved my day in a sad and happy way. kexp.org

Auto - formatting code in JupyterNotebooks can be done with a single click! 🖱️✨ Auto-formatting code in #Jupyter Notebooks can be done with a single click! With this wonderful extension:

One of the most interesting projects/tools I came across recently is Jujutsu, a #Git compatible VCS that is both simple and powerful: github.com/jj-vcs/jj "What if we actually could replace Git? Jujutsu might give us a real shot." [Chris Krycho]

I started with #Python 20 years ago. Every few months I re-open Brett Slatkin's "Effective Python: 125 Specific Ways to Write Better Python" and learn something new. Fantastic resource for everybody who knows a bit of Python and wants to improve their style: effectivepython.com

Today I had fun finding out that #ImageMagick can be used to count objects in an image (my example was to process generated "telescope" images of stars which I use in teaching parallel computing):

Sustainability isn't a race or marathon. It's a relay, and you have to be ready to pass, or grab, the baton when the time comes.

Deploy your Jupyter Notebook as a static web app! 🚀 I recently built a small app with ipywidgets in a notebook and recorded the process of deploying it to GitHub Pages using Voici. 🛠️ Watch the full video here: youtu.be/H4Zt1vHWbJc

Today I was teaching #dataviz to a room full of #Python novices. Very first notebook failed for everybody except me. I was the only one on Python 3.12, all learners just installed the freshly released 3.13. TIL: Define the Python version in the environment.yml that you hand out to learners.
