jwz, still sticking to emacs 22
i noticed, old people don't learn. most of them anyway. here's jwz, still sticking to emacs 22. https://www.jwz.org/blog/2018/08/now-you-have-two-problems-el/
emacs xah-fly-keys tip: SPC m runs dired-jump
Also, never do M-x dired nor by key. Work based on file only. Leave open a file of of a dir you want. Then, on any file buffer, jump to its dir. e.g. in bookmark, mark file only.

Xah HTML Mode update
Emacs: Xah HTML Mode
① xah-html-remove-html-tags now move cursor to next tag after call. ② xah-html-wrap-html-tag now insert class="…" directly without prompt. ③ when video or audio link is linkified, attribute “loop” is added.
btw, the same thing is happening in emacs MELPA. thousands of packages, nobody really checks the code. The general problem is, nobody want to pay (e.g. a professionally monitored repo), and most people are lazy.
emacs MELPA code is looked when submitted, by https://twitter.com/sanityinc and other devs (i think https://twitter.com/milkypostman (the creator) and https://twitter.com/magit_emacs ) but not when updated. it'd be full time job to security check on all update.
for me, i ALWAYS check before i use a emacs package. 10 min would do. you can check the author reputation to establish a trust. or, scan the elisp code. Most popular packages on MELPA, their authors are usually well known in emacs community.
Rich Hickey ( clojure creator ) rant on open source
basically, it's a conflict of interest between project owner and code contributors.
you have to also look at the context and the other side
[ https://twitter.com/cemerick/status/1067111260611850240 accessed: 2018-11-27]
I think Rich Hickey is right. Basically, the open source ideology becomes a monster. Originally, it's that someone very nice, put time and energy to create software, free, with source code available. And, someone else saw it, also very nice, spent time and energy to contribute. Normally, both the owner, and the contributor, should be regarded with highest esteem. And, the relationship of owner and contributor is a friendship. You two work together only when both person like each other. It has no governance, all pure human endeavor and good will.
However, the ideology of open source and FSF turned into a monster. It became, some kinda public service machinery that churn out software, with “code of conduct” fak, that somehow the creator owe you something when you have a problem. And that somehow taking your time to give freely as contributor is also a right and a duty and a way to benefit urself or something.
This is exactly what big corp like you to think. Software from Google, Apple, Facebook, npm, etc. They, are proprietary+evil to the hilt, yet use open source as badge of sainthood, and have code of conduct that somehow says it's your human right to give your time and energy to them, meanwhile that pseudo legal verbiage works to axe you when they see fit.
can emacs plugins be sold does anyone sell plugins
most posts in this thread is misinformation.
- rms sold emacs himself for perhaps a decade. emacs was considered expensive. vi is free.
- Lucid inc, the creator of Lucid emacs that became xemacs, did not “sell” its stuff on top of emacs. It was free and explicitly open source from the beginning. see https://www.dreamsongs.com/DiBona-OReillyLetter.html
- if you try to sell a emacs package, you get maybe $100 per year. (meanwhile, you get a lot hate and most emacs online people shun you.)
- 1 in maybe 10 thousand people, become a open source star (e.g. rms, linus, npm, nodejs, redhat, ubuntu etc.). There is some price to pay. e.g. You never voice opinions that contrary to the mainstream. Unless you are rms or linus. You must constantly sell the open source ideal, with words like “help”, “contribute”, “thank you”, “make the world a better place” etc.
- you find ways to work around. e.g. be nice and sell emacs book. e.g. https://www.masteringemacs.org/ each time it is mentioned, lots people highly recommend it, i think more as a gesture.
- you find a way to change it to service, or cloud. (e.g. redhat, ubuntu.) Typically, they become nasty as any commercial corp. e.g. Ubuntu, Firefox.
- typical star open source software are done by people working in proprietary corps (Google, Facebook, Apple) as off hour hobby. Quite a few most popular emacs packages are like that. Or, statistically, most of emacs packages on Melpa.
- the moment you voice displeasure with open source or FSF, there is an army forking your software, explicitly in-your-face or implicitly quietly.
- vast majority of open source, when popular, they become proprietary, or semi proprietary, or in general go ALL SORTS possibly imaginable ways to make it impossible for average programer to fork/resell. e.g. GeoGebra, npm, Google Chrome, Firefox, Apple, etc.
see in depth survey:
[Why Utopian Communities Fail By Ewan Morrison. At https://areomagazine.com/2018/03/08/why-utopian-communities-fail/ ]
If you really believe in open source, or FSF, do not work for any proprietary software company (no excuse whatsoever) , do not use Apple products. rms is a great example of this.
PS am grateful for the donation i've got. I keep opinion as is. Cowering doesn't work, and actually make things worse. Those who donate to me already knew this. Thank you.
has any written a Eliza using Google TensorFlow?
How much you type per Day?
on reddit https://www.reddit.com/r/emacs/comments/9znxm9/how_much_you_type_per_day/
This means, i type about 13k keys per day. Assuming 50 wpm, typing everyday, then i type continuously for 60 minutes per day.

emacs xah-fly-keys tip: 【space , ,】 → delete-frame (close window) in dvorak it's 【space w w】
emacs does any use imenu? can u describe use case? afaik, M-x imenu, then type a function name, it jumps to it. Isn't it faster to M-x occur defun and clearer with overview?
addressing your first comment, the problem with control+tab is that you have to hold it, and have to eye ball. In other words, depending on how severe or how much you actually type, holding control is a big no no. And, eyeballing things is a cycle drain on your brain.
i'm speaking in the context of extreme efficiency and RSI suffering. For example, if you log your keystrokes, your daily average is actually equal or greater to professional typist continuous typing for 1 hour. (For most people, it's much less than that.) And or, if you are not young. And or, if you already have hand pain.
holding any modifier, or holding mouse button (e.g in drag), is 1 of the first thing any Repetitive Strain Injury sufferers should avoid.
In another context, in speed typing (as in competition) (or speed emacs operation competition), holding modifier is also a no no.

open source lies and story of emacs history
The open source lies, year after year. And rms's lies. They never get corrected.

my emacs videos
my emacs video experience is pretty disappointing so far. 1 or 2 hundred views per vid, after a few months. Other usually have few k or tens of k views. 1 problem, is my subjects r not common basic tutorial, or, showing specific feature.
for example, 1 such focused topic i did, is my emacs abbrev demo, which has 600 views.
This is quite annoying. 1 fix, is to do focused common topic. E.g. Emacs intro. Dired basics. Shell/eshell basics. Efficient ways to open files. Some of these are boring to do. Another fix, is to do regularly, a lot, like 3 per week, like a talk show, n chatty. This am more inclined.
Emacs: Remove Accent Marks
major update. now works on vietnamese text.
now xah-find.el can correctly handle output from find or find/replace script written in golang. The image is output of golang, then emacs M-x xah-find-output mode. Next step is to integrate it into xah-find.el . So, you have speed of golang for grep/sed but nice UI of emacs.
