“Everybody should have an obsession with Lisp-like language at least once in their life” @KevlinHenney

Posted by jpluimers on 2025/08/27

The tweet [WaybackSave/Archive] Jakub Kočí on X: “”Everybody should have an obsession with Lisp-like language at least once in their life” @KevlinHenney I’m glad that I had one with Clojure.” mentioned a great talk:

[Wayback/Archive] The Past, Present & Future of Programming Languages • Kevlin Henney • GOTO 2024 – YouTube

The quote brought instant memories to my early computing days that I had almost forgotten: the muMATH (the muMATH-80 version on Apple II) computer algebra system which was based on muLISP (the German muLISP page has more detailed information), a LISP dialect.

In retrospect, I was way too young to really grasp LISP which was way harder than just using the muMATH wrapper. But it was also my first encounter to reasoning systems, or what we now collectively would call AI systems as back in the 70s there was a strong LISP connection to artificial intelligence . Do not confuse muMath with MuMath-Code however, that is a different LLM beast: [Wayback/Archive] GitHub – youweihao-tal/MuMath-Code

So hopefully I will have a chance to revisit LISP with a LISP-like language one day, maybe even using the discontinued muMATH-83 on MS-DOS (also named “Microsoft LISP“), maybe even the (also discontinued) Derive 6.1 for Windows which is also based on muLISP, or even Clojure itself.

In case I ever want to import another SVN repository into GitHub (for instance form SourceForge)

Posted by jpluimers on 2025/08/27

The odd thing is that SourceForge has (sf.net) a GitHub project importer (for more than 10 years now!), but not vice versa. You can import a SVN repository in GitHub, but that’s far from importing a complete sf.net project.

More on the importer to import GitHub to SourceForge below, but first the other way around:

These steps worked to get xn-resource-editor.sf.net into github.com/jpluimers/XN-Resource-Editor-TWM (which I did because the GitHub web UI is so much better at browsing and searching commits and files than the SourceForge web UI):
