Love attention to details like these

The videos are pre-recorded, but after the video there is a live Q&A section. Come and join the IRC channel. It's a lot of fun.

Was this an exceptional measure or a planned new kind of organization ? It's interesting.

This format started in 2018 or 2019, I can’t recall which.

Can you watch it purely in Emacs?

Depends on your definition of "purely". I will watch using an mpv managed by EXWM so it will be showing up as an Emacs buffer. Or you could use the embedded video player in EAF.

Please post a link for setting this up. Thanks.

EDIT: found https://wiki.archlinux.org/title/EXWM I would like to try that on an old Linux laptop

Cool, but completely off-topic.

Only partly so, I'm stretching it a bit but HP Calc's RPN is inspired by lisp, and emacs calc is in turn stack based, just like RPN :) It's a big cross pollinization fest.

RPN is forth not lisp, and I seriously doubt HP got their idea from emacs. I think HP's RPN precedes the first release of emacs anyway. Edit: 1st release of emacs was 1976 so I take that last bit back.

As with the high vote totals for Firefox-related links, the presence of a link on an ancient* text editor at #1 on HN (as I write) reveals that HN voters are a bit ... old school.

> These tools' relative importance has declined over the last 15 years. I would say to the contrary. There has been a flurry of new development on Emacs in the recent years initiated by a new generation of developers. New (and simpler) search and autocompletion frameworks (Ivy, vertico), native compilation of Elisp, the rise of Org and the advent of LSP clients (thx VScode).

While LSP can support semantic highlighting, it's often used for navigation, ala goto-definition. I think there is little overlap between Tree-sitter and LSP.

Sorry, I mistyped. I was thinking about HP42 and above RPL not the basic RPN. RPL is a blend of lisp idiom on top of good old stack based RPN (list, map, numerical tower). It goes so far that they even added quoted lambda expressions. You could push + a a >> on your stack.

It's use of RPN wasn't, but RPL was with one meaning for it being "Reverse Polish Lisp".

Good to know! For as much as I use Emacs I don’t really follow the Emacs community / ecosystem. I saw version 29 was recently cut- is there anywhere I can get a good overview of “best practices in 2022”? I wouldn’t mind dusting off my init.el and updating it. I haven’t had a good yak shave in five years or so :)

https://blog.phundrak.com/emacs-29-what-can-we-expect/ has some highlights. eglot, tree-sitter are both very nice. the sqlite integration is currently what i'd describe as "cute", but maybe not the most featureful.

I'm shocked that ast based edition is back. Many people were against this, lots of grammar based tools sadly failed (for better or worse reasons). In a way it seems that the mainstream rose above regex level tree manipulation, and that even html/css made people start to think in subtrees rather than linear data. This might reduce efforts a lot, whether it is for edition or analysis.

And this fine grained source interaction was why I was so enamoured with emacs in the first place. It was such a deep feeling of control compared to anything I tried in the late 90s.

Oh no, I missed half of it already when reading this.

Well, in theory I could watch a lot of recordings any time later. But in practice I hardly ever do. If I decide to attend a conference, I spend the day there, even if it's at my desk. (Or the night, hello Linuxcon Australia). If I don't register and attend real-time I will never find the time to watch most of it.
