How successful has the SciML Small Grants program been at getting newcomers to contribute to open source software #oss for #sciml #julialang and #ai4science? Very!
* 13 total projects initiated
* ~90% success rate
See the blog post summary of the first year!

New blog post on the use of the Xref code navigation feature of Emacs, specifically for working with Julia source code.
New article published today in the Computers & Chemical Engineering journal: *A multi-agent system for hybrid optimization*. This paper is based on the work presented last year at the European Symposium on Computer Aided Process Engineering (ESCAPE 34) conference.
One key lesson I took away from this work: how easy it is to write efficient and effective multiprocessing code in Julia. And how much fun it is actually.

Julia v1.11.6 has been released
Why do these two lines in Julia produce different results?
Solved: the code is parsed as: (1,2) .|> x -> (x |> sum) Wrapping the anonymous function solves the problem: (1,2) .|> (x->x) |> sum

What if you could just wave a magic wand over your R #rstats 
code and have it transform into something that ran as fast as or faster than C? @t_kalinowski's {quickr} 'R to Fortran Transpiler' does that for you! #fortran
With bonus comparisons to #Rcpp #julialang 
and #rustlang

Evaluating of simple #additivemanufacturing cost function metrics (build height, footprint area, support volume, overhang area, ... ). The model is rotated and all metrics are computed, next the sphere is "painted" to show the magnitude of that metric for that orientation (sum of the lengths of the black lines as estimate of support material use). This way the sphere provides a nice summary visualisation of which orientations are best e.g. in terms of minimising support material use.
New blog post where I talk about connecting Julia and python for optimization:
When someone says: "There's this great dynamically-typed programming language with a useful and expressive type system, powerful macros and multiple-dispatch that solves the 'two language problem' (meaning that you can quickly and comfortably write a prototype in the language but then also write the fast production version in the same language), that has roots in academia but with uptake in industry, a great interactive coding experience in the REPL (including the ability to show you the assembly code for any function!) and [an] excellent compiler[s]" you don't know if they're talking about #CommonLisp or #JuliaLang until they choose either the plural or singular for the word "compiler"! 
Just a bunny rotating according to a uniform set of directions on the sphere. The bunny is colored towards the "overhang" angle with respect to the ground. The black area on the ground is the projection of the bunny onto the ground (a bit like a shadow). This is a simple toy simulation that computes some metrics relevant to the simulation of 3D printing preparation.
So, is there any hope that the new #iPadOS26 will re-enable support for virtualization? Or at least allow running things like #vscode or #julialang? Or does the #iPad remain a vastly overpowered toy?
I have started a new blog which will present musings on coding for my research in optimization and its application to industrial engineering problems. I code mostly in Julia and always using Emacs.

I will post here when new blog posts are posted. I'm hoping to create an RSS feed for the blog in due course.
The blog is written in org mode in Emacs (of course ).
