Update to ‘An Annotated Mathematician’s Apology’, with a new section on Wittgenstein’s response: https://archive.org/details/hardy_annotated (accessible #TaggedPDF, #OpenAccess)

My thanks go to Wolfgang Kienzler, professor at Friedrich Schiller Universität in Jena, who pointed me to Wittgenstein’s remarks, sent me notes about relevant sources, and critiqued my draft for the new section.

For newbies feeling hesitant or frustrated about #Emacs and its Lisp flavor. tl;dr #Foss #lifelonglearning victories!

In 2010 or so I watched an interview with the immortal Carsten Dominik, creator of Org mode. He made an offhand remark to the effect of "I just love coding in Emacs Lisp, it's just how I think, it's just so natural, don't you agree?" And I was very unhappy. Because I could not agree. That discouragement stuck with me.

My wife always says "the time is going to go by anyway," and this is wisdom. By 2023 I had written "org-teach" for producing classroom materials, shared it at EmacsConf, actually used it in the wild. Others around here have done similar, @randyridenour @ericsfraga @asilata sorry if I'm forgetting you.

Long story short, the underlying #TeXLaTeX core couldn't do #taggedpdf until 2025. I asked on here for help and @yantar92 went to the mailing list and before I could say meta x @paaguti and @schuemaa had us all sorted out. So grateful!

With these significantly changed dependencies I decided to rewrite the jank that was org-teach from scratch. And it feels like lightning shoots from my fingertips now. I can implement functionality almost as fast as I can think of it. Too messy to share quite yet. But this kind of workflow and software self sufficiency feels like a superpower. Emacs Lisp just feels natural now. After only a decade and a half!

But seriously, all my progress is thanks to this community.
