I'm sure someone has already invented a #python wiper that gets rid of all stray python installations, venvs and package managers. After two versions of poetry, a conda episode (better say: accident), a switch to uv, inconsistent use of pip, pipx and python installs via #homebrew, and installs via miniconda that #julialang and #quarto sneaked up on me, there is absolutely no way to make any path to anything work in any virtual environment and I need a new laptop. So what's the python wiper called?

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. 🙂

Proud to say that last night before bed I suggested that fitting problems with our migration model might be fixed by switching to a local basis for a certain function. I described the use of compact radial basis functions, and by the time I woke up my student had implemented them in pure #Julialang and said that fits were now fast and seemed good quality. Its great to work with a student with that kind of talent, and a language that enables that kind of rapid exploration.

What if you could just wave a magic wand over your R #rstats :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 :julia: and #rustlang :rust:

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.
