Can you access the new `juliaup gui` on macos with juliaup installed with brew?

I just get an error: GUI binary not found at '/opt/homebrew/bin/juliaupgui'. The juliaupgui component may not be installed.

Juliaup 1.22.3

I get a feeling they intended the whole 1.13 syntax highlight system as more of a programmable interface, so there's a little bit of additional work for people like me who just wants highlights out of box.

I can see there being a Julia module for syntax/repl styling collection in the future, which could be interesting.

#julialang

If you're like me and wondering what's happening with built-in syntax highlight in #Julialang 1.13. Some of your usual code highlighted under OhMyREPL might show up as regular texts since default in 1.13 is VERY conservative about highlights.

You need to copy in the monokai example from repl doc page as faces.toml in .julia/config to get something closer to OhMyREPL experience.

Julia v1.13.0 release!!!

Hmm - I hope this is just me, but if you were using Julia for any production level stuff I'd hold off on updating to 1.13 for now.

Running into strange errors if my config/startup.jl contains references to OhMyREPL, and also running into bunch of precompilation errors in different environments I didn't see before update.

#Julialang Julia 1.13 is out! I see they have built in repl syntax highlight. How does it compare to OhMyREPL? Is it time to retire a piece of my setup?

Also it looks like juliaup ships with gui - I have mixed feelings about that one. Why not just have a separate gui option for download? Juliaup isn't the most complex cli program out there, so I'm not sure who this is aimed at.

I"m taking a few minutes to check out the Julia Language and see what I could do with it.
Does anyone use it for bioinformatics or public health?

🌍💻 Networking week for our group! This week, members of our team represented our working group at two exciting international conferences — one focused on cutting-edge programming, the other on the icy frontiers of Antarctic research! 🧊 Christian and Gunnar attended the #SCAR2026 Open Science Conference in Oslo with great discussions about Antarctic science and policy! Especially, a lot of good input and ideas for the upcoming @AntarcticaInSync and IPY5 initiatives were presented. 💻 Marcus joined the JuliaCon 2026, diving into the vibrant community driving innovation in scientific computing with the Julia programming language. We're happy to see our team engaging with such diverse and impactful scientific communities — from the depths of Antarctic ice to the frontiers of computational tools! ❄️👩‍💻

Am really enjoying using Julia as a pseudo-shell.

I needed to chop up some pdfs and rearrange the pages. Poppler-utils is great but I never really learnt Bash scripting so it was going to be a bit of a slog.

Thankfully, Julia makes it really easy to bulk copy or move files in mostly regular sequences

So, the Roller Derby World Cup happened from 3-6 July in Innsbruck, Austria. Our hosts Fearless Bruisers Innsbruck were extremely hard working, and from the 1st to the 7th (including set up + teardown time) we worked with 6 THOs, 2 THAs, 2 THPs and three GTOs (and 9 officiating crews, dozens of announcers and photographers, and a host of volunteers, along with our streaming tech friends at Real-Time Events) to make the world's largest Roller Derby event in history happen.

Despite this record-breaking scale over 5 tracks and 80 games, each of our 48 teams only played 3⅓ games on average. In order to make it possible to effectively run the equivalent of a qualifier, "group stage" and elimination all in just 4 days - with 6 teams entirely new to Derby! - we needed to use a tiny bit of statistics.

The advantage of the stats is that we can present you with a considerably richer "final result" than most sporting events would - estimating not just final ratings but also our errors on those ratings.

Code for this graph is open to the public at https://codeberg.org/aoanla/RDWC2025 (the game data needed will be uploaded very soon).

Working on automated parameterised meshing of #FiniteElementAnalysis of periodic auxetic structures.

Built using the Comodo project:

Working on nested triply periodic lattices. Here a Gyroid levelset image is created and two interwoven/complementary surfaces are obtained by constructing isosurfaces for the same positive (white) or negative level (red). In the animation the levelset level is adjusted so the surfaces "shrink away" from each other.

Working on extruding or "thickening" meshes from surface elements to layers of solid elements. Here the test mesh features quads (left) which are thickened to produce hexahedral elements (right).

This is especially handy when one wants a high quality structured mesh of a thin structure. For instance meshing of blood vessel like structures.

TetGen functionality has now been added to Comodo.

Octonions.jl v0.2.2 extends all complex analytic functions in the standard library to the #octonions!

Octonions are a type of hypercomplex number whose product is neither associative nor commutative. Besides their normal uses, they are also useful for testing numerical algorithms that are intended to generically work for even weird numbers.

Here we use them to check that the fallback QR and unpivoted LU decompositions in #JuliaLang do the right thing.

Having fun with Makie.jl and Ferrite.jl in FerriteViz.jl. My colleague Dennis and me added support for gradient/flux visualization based on a known finite element field: https://github.com/Ferrite-FEM/FerriteViz.jl/pull/51

We started FerriteViz for teaching purposes and this PR adds very nice possibilities to it. With this PR, instabilities in mixed forms or singularities in the fluxes can be visualized. 🎉
