Last time I exposed an old way learned in physical labs to do C or python/tk like in the old days: by summoning a tcl/tk interpreter and piping commands to it. But what fun is it? It's funnier if the tcl/tk interperpreter talks back to python :D as an hommage to the 25 years awaited TK9 versions that solves a lot of unicode trouble. Beforehand, to make sense to the code a little warning is required : this code targets only POSIX environment and loses portability because I chose to use a way that is not the « one best way » for enabling bidirectionnal talks. First and foremost, the Popen no ..read more

I have adopted uv for a lot of Python development. I'm also a heavy user of direnv, which I like as a tool for setting up project-specific environments. Much like Hynek describes, I've found uv sync to be fast enough to put into the chdir path for new directories. Here's how I'm doing it. Direnv Libraries First, it turns out you can pretty easily define custom direnv functions like the built-in ones (layout python, etc...). You do this by adding functions to ~/.config/direnv/direnvrc or in ~/.config/direnv/lib/ as shell scripts. I use this extensively to make my .envrc files easier to maintain ..read more

Well, the PySimpleGUI pull rug of licence reminded me how much dependencies are not a good thing. Even though FreeSimpleGUI is a good approach to simpler tk/tcl binding in python : we can do better, especially if your linux distro split the python package and you don't have access to tkinter. I am watching you debian, splitting ALL packages and breaking them including ... tcl from tk (what a crime). Under debian this stunt requires you to install tk : apt install tk8.6 How hard is it to remove when tcl/tk is installed to do GUI programming in tk without tkinter? Well, it's fairly easy ..read more

Earlier this week I considered whether I should finally switch away from virtualenvwrapper to using local .venv managed by direnv. I’ve never seriously used direnv, but I’ve been hearing Jeff and Hynek talk about their use of direnv for a while. After a few days, I’ve finally stumbled into a setup that works great for me. I’d like to note the basics of this setup as well as some fancy additions that are specific to my own use case. My old virtualenvwrapper workflow First, I’d like to note my old workflow that I’m trying to roughly recreate: I type mkvenv3 <project_name> to create a new ..read more

We are excited to announce the launch of the scikit-learn user survey! Scikit-learn continues to evolve thanks to contributions from its diverse user community. As we plan for future releases, we want to ensure we are focusing on what matters most to you — our users. The goal of this survey is to better understand how users interact with the library, identify any pain points, learn about the features you find most useful, and what’s missing. This is your chance to have a say in how the library grows and adapts to meet the evolving needs of the machine learning community. The survey will take a ..read more
