Hand Exercise Toys for Repetitive Strain Injury

Found a good putty and squeeze ball designed specifically for Repetitive Strain Injury.

there's a item called Think Putty, but it's not really good as a hand exercise toy because it's more of a science toy, with bits of metal in the putty. If you leave it on the carpet, it'll melt into the carpet as one. Rather nasty. I read a lot review of it on Amazon.

For a hand exercise putty, you want one that doesn't smell, doesn't leave grease on your hand, stays in one piece, and not too soft as clay. this one: Thera Flex Therapy Putty Medium Resistance. And it's much cheaper than the science toy magnetic putty thing.

Also, there are squeeze rings, and squeeze balls, designed for Repetitive Strain Injury. I've gathered a collection of them, all updated, at the bottom here: How to Avoid the Emacs Pinky Problem (updated. Refresh page.)

Emacs: Why You Should Not Swap CapsLock and Control

sometimes i got ridicule on this. Perhaps it's not for everyone's hands, and very much depends on the keyboard you are using.

Google search “emacs palm to press control key” and you'll see many people using this method too.

yes, i use this method to press the control key, started sometimes around 2006 or so. You can see a video of me doing it at http://youtu.be/tkjm1xSF4g0?t=1m2s

Emacs Best Shell Practices

Guanghui Qu asks:

Are you running a shell inside Emacs? I have heard shell, eshell and ansi-term, what's the best practice to work with shell inside Emacs? or should I use shell outside of Emacs? Any suggestions will be helpful to me. Thanks.

“xah-filter-list” and “xah-string-match-in-list-p”

Coding is tedious. T E D I O U S.

spend a hour to write these today:

[see Elisp: Filter a List]

[see Elisp: String Match in List]

haven't had time to polish it.

they are dumped in “xeu_elisp_util.el” at github.

why i wrote them? here's the problem.

i have a list of files generated by

(find-lisp-find-files $inputPath "\\.html\\'\\|\\.xml\\'")

but i want to filter out some directories. In any other lang, including bash or unix util, you can easily add a option or filter. Emacs lisp can't do. The “find-lisp-find-files” is some kinda obscure function few know. Not much documentation, and not very flexible. So, i had to write my own.

so, the code now is:

(xah-filter-list
 (lambda (h) (not (xah-string-match-in-list-p h $skip-list "match case" t)))
 (find-lisp-find-files $inputPath "\\.html\\'\\|\\.xml\\'"))

it's at “git/xahscripts/elisp/xah_site_move.el” (by the way, this is one of the larger code i spend a couple weeks to write. It is used to split my site into several domains. Basically, given a directory D, and a list of pairs, each pair is 2 full file paths, from and to. Correct all relative links of html files in D according to the from/to pairs. The code is about 1k lines. The bulk is at “xah_emacs_xahsite_path_lisp_util.el”. The task is quite more complex than i imagined. (i wrote them in ))

i haven't done much emacs blogging in past week. Mostly focusing on writing my tutorials on JavaScript and Web Dev.

Matt is working on http://ergoemacs.github.io/ diligently as always. Code commits and answering bug reports patiently every day. Every other day i git pull, hundreds of line changes. Amazing.

Mastering the Tools of the Trade

Several tutorials for programers:

I spend 5 years to write them. You spend 5 minutes to read them.

If you are a computer science college student, or if you are pro programer in lang X and want to learn lang Y, then read them. Just these, and the spec or official documentation. (usually linked from each page)

if you like them, you can buy all. Entire xahlee.info, formatted for offline reading. ∑ Xah Code

Future and Policies of Books

I got this in my email, from Amazon: http://www.readersunited.com/

it's not about emacs, but about policies and future of ebooks. In short, there's a dispute between Amazon and another big company. Amazon, claims to want to lower price of ebooks, but the publisher refuse.

If you have any interest in policies in society and books, check it out.

Master JavaScript in 1 Month

again, heavy work on JavaScript in past month. Result of 1 year study. More complete and in-depth than my 8 years emacs lisp haphazard blog effort.

web programing, tablets, phones, are the most vibrant field in programing since perhaps 2008. JavaScript rules there.
