The Julia Language Slack

Congrats on the new package!

You might be interested in joining the Julia Slack and the #health-and-medicine channel where us JuliaHealth folks live. We are growing quite steadily and would love to hear what you are up to!

Also, why the fury about docstrings? What features are you missing?

🔎 Temporal graph theory (dynamic graphs) is nifty

🤯 Introduced by Wilmer Leal & learned more from Aurora Rossi + @carlolucibello.bsky.social's work on GraphNeuralNetworks.jl @juliacon.bsky.social.

🧠 I want to read more; suggestions?

❓How do you track graph changes?

The cult of the Framework Julia users continues to grow!

Some members of JuliaHealth this year!

That's a wrap for @juliacon.bsky.social 2025 for me! 💥

Great meeting JuliaHealth folks in person, having our first-ever Mini-Symposium, & planning for the ecosystem! Thanks to all who attended!

Ready to recharge & build #opensource!

P.S. Snagged our annual #julialang @frame.work group photo too!

One of the most iconic visualizations from W.E.B. Dubois

I absolutely adore the viz work of W. E. B. Dubois.

Not only was it pioneering the art of scientific communication but also paved the way for discussion around racism, disparities, and other quantities that we take for granted in sociological contexts.

Made a public dev log of using #julialang and a #raspberrypi to make an e-ink dash! 💻

Feel free to join in the adventure! 🤠

Doing this to log my discoveries and thoughts. ⚗️

Who knows? Maybe there can be a bunch of E-Ink Julia dashboards floating around the world soon! 😁

Oh that sounds fascinating! What sorts of projects do you tend to work on? I am slowly rediscovering my love of hardware hacking and hardware engineering so would love to hear more!

Per Julia LTS (1.10), you could refill water, make a cuppa tea, and sit back down to continue hacking on the Pi! 🍵

Story is great; Pi 4 only has 4GB RAM. Did expand swap to 2GB (overkill) for compiling but... Not bad. Will share future updates! 🔮

No problems with #Julialang in my non-hobby work. 🤓

Thanks for the kind words! More updates to come!

Yea, the cost is quite prohibitive. Could be nice to have nice "at-a-glance" displays for random useful info.

After half a year of hobby #hacking, got an eink interface working w #julialang! 🎉

If you are a #maker or #hobby #programmer, what other sorts of modules can you think of?

Open to ideas and suggestions about what has been useful or informative to you!

#maker #raspberrypi

A fine assemblage of mathematicians, computer scientists, and engineers from across the globe all united to discuss applied category theory!

Finished a great week at the International Conference on Applied Category Theory! 🤓

Made great connections, reconnected w old friends, and came away w new ideas! Our talk on ACSets was a success - excited a/b the future of compositional data science & public health! 💥

Gainesville was so much fun too! Tons of hiking, some dancing, and great little city to explore! 🕺

Here are some fun photos!

If you're interested in our work, here's our slides! 📈

Eager to wrap up the work in AlgebraicJulia and to finish up a paper describing a unified "Data Fabric" in the language of Attributed C-Sets. 📝

We are aiming initial applications in the world of public health! 🛟

Hello Friends!

I'm on the job market now!

I have a oodles of knowledge for all the software performance engineering tricks in Rust, Julia and other systems languages and would love to work with teams that are looking to skill up in those respects, from back ends to big data crunching!

Patient Level Prediction in Julia Blog Series NOTE: JuliaHealth contributor, @kosuri-indu, wrote a great series on Patient Level Prediction Julia workflows! She can’t post links to Discourse so I am posting her work below! Introduction Hello ev...

My mentee, Kosuri L Indu, just finished writing a blog series on Patient Level Prediction workflows within #julialang!

Our approach is inspired from OHDSI (Dr. Jenna Reps's work in particular), #rstats, and precision medicine going from phenotype definitions to real world evidence!

JuliaCon 2025 JuliaCon 2025, Pittsburgh

For the past year, I have been co-PI of a cardiooncology research study on 35 million patients using Julia methods for PLP.

If you are @juliacon.bsky.social this year, you'll get to hear more!

Learned a lot & excited about publishing and developing more research software for PLP!

#academicsky

In the series, we explored how possible it is to do PLP within Julia.

Good news: Julia's composition is killer; we get deep functionality for ✨ free ✨

Bad news: workflows are still rough

Hopeful news: we are building ergonomic tools to make PLP easier and lots of long-hanging fruit available!
