Det undrer mig at borgerforslag ikke er mere brugt. De 25 forslag der er oprettet i maj måned har i alt fået 50621 støtteerklæringer. Deraf 46585 på et enkelt forslag.

Borgerforslag Borgerforslag.dk er oprettet af Folketinget for at håndtere ordningen om borgerforslag. Her kan du stille borgerforslag, finde forslag, som andre har stillet, og støtte borgerforslag.

www.borgerforslag.dk er et sjovt sted. Måske har jeg bidraget til at:
• Børn skal bruge cykelhjelm
• Vi slipper for reklamer for gambling
• Vi kan få billigere søkort
• Vi kan få billigere og bedre banker h
• Vi kan få atomkraft
• Vi kan få bedre sociale medier

GitHub - openai/codex: Lightweight coding agent that runs in your terminal Lightweight coding agent that runs in your terminal - openai/codex

hands down, the biggest news is codex

open source Claude Code, but with OpenAI models

no MCP or Azure support yet, although it is open source, and PRs emerged 30 min after the live stream ended

Makie.jl is amazing. It keeps improving at an impressive rate. Great to learn about the Souvereign Tech grant. Thanks for all the hard work.

Today I was reading in Kernighan and Ritchie: The C programming language. It is a pleasure to read. What are the best books about programming languages you know?
The @julialang.org manual is great, though the examples are not as profound as K&R’s

Tidier.jl with Karandeep Singh
YouTube video by Julia Dispatch Tidier.jl with Karandeep Singh

Why is #JuliaLang a great home for a flavor of the tidyverse? What does Tidier.jl do? Will you get sent to Julia jail for using an ecosystem inspired by #rstats?

In this convo with @chrisrackauckas.bsky.social and Michael Tiemann, I don’t have answers, but I have thoughts!

I has happy with Twitter. Tried Mastodon, but did not find as many interesting things there. Now hoping Bluesky will become the new Twitter.
