The Atreus keyboard started in 2014. atreus keyboard by Phil Hagelberg 2015-06-17 Atreus keyboard by Phil Hagelberg. 42 keys. 〔image source ©〕. The interesting thing about the Atreus is that it doesn't have the top row of number keys. And, it doesn't have the key columns on the sides neither.

Emacs Lisp: Replace Invisible Unicode Chars.
twitter started to use OBJECT REPLACEMENT CHARACTER (codepoint 65532, #xfffc)
http://ergoemacs.org/emacs/elisp_unicode_replace_invisible_chars.html
When copying text from Twitter or Google Plus, often you'll get a invisible ZERO WIDTH NO-BREAK SPACE, that's really annoying. (this is so at least from 2012 to 2015 ). Here's a command to replace BOM mark character. (defun xah-replace-BOM-mark-etc () "Query replace some invisible Unicode chars.

#emacs major mode keys not compatible as key sequence http://ergoemacs.org/misc/emacs_major_mode_key_not_sequence.html
emacs key conventions are truly the worst possible. suppose you have a Kinesis Keyboard with extra keys. So you want to make a thumb key as the prefix for all major mode keys. You can't! by convention, personal key space start with 【 Ctrl + c 】 then followed by a letter.

#Emacs
again, about the xah-find.el package. If you haven't used it, give it a shot.

It's super useful for search in project, refactor/change names, grep/sed in Pure Elisp
http://ergoemacs.org/emacs/elisp-xah-find-text.html

It solves several problems of calling unix grep. See

Problems of Calling Unix grep in Emacs
http://ergoemacs.org/emacs/emacs_grep_problem.html

here's the unicode bug. Linux Shell Util uniq Unicode Bug
