Keyboardio, Computer History Museum, SGI
the Keyboardio Keyboard is going to have a demo at Computer History Museum on . That's neighbor to Google Headquater Googleplex, in Mountain View, California.

here's my analysis of its design. Keyboardio Keyboard Model 01 ⌨
by the way, the building that's Computer History Museum has a rich tech history. It was a brand new office building of SGI's headquarter. Do you know what SGI is?
SGI was the biggest name in computer graphics back in 1990s. They make IRIX, which is their version of Unix (which today we pretty much just have Linux). Irix, HP-UX, AIX, and even Apple, had a unix OS called A/UX. SGI also makes very expensive, bleeding-edge, computer hardware for creating 3D graphics (back then, desktop unix computer is called “workstation”. There's not much of a PC yet.). SGI also was the owner of Cray for a while, which is the world's most powerful super computer. SGI was the one who created the special effects of the movie Jurassic Park (1993). At the time, it was a break-thru.
SGI makes 3D modeling software, at various times called Alias, Wavefront, Maya. (now owned by AutoDesk, maker of AutoCAD)
When i was student around 1992, waiting for bus, i ogle at the buildings of computer companies, where, offices are filled with very expensive workstations, and lots of geek toys. I was thinking, when could i ever be able to work in such a place.
Since 2000s, PC becomes cheaper and powerful, and 3D modeling software sprung up left and right, and free Linux is spring up as unix server replacement. That killed SGI.
Today, the one thing from SGI that's still around is OpenGL, and, isn't particularly healthy.
The once brand-new building of SGI, changed owner a few times, and now it's Computer History Museum.
O, sweet history. Sun Microsystems, the creator of Java, once also reined the computing world with their Solaris OS and server hardware. Sun is also dead, bought by Oracle, which never had any cool factor.

though, also discovered, there's a problem of this keyboard under linux. It spams 666! (but works fine on Mac)
Logitech G710+ Mechanical Keyboard
if your main machine is linux, i don't recommend it because of this.

Gnu Emacs New Leader: John Wiegley
Wiegley as maintainer was discussed in the gnu emacs dev mailing list for the past couple of months, hundreds of messages.
John Wiegley is the author of eshell〔➤ Emacs: M-x eshell〕, a compiler engineer for like 20 years coding in C++, and is now a professional haskell programer. He lives in emacs.
Here's a couple of video interviews of John. John Wiegley on Emacs Lisp and Haskell
John is a extreme emacs enthusiast, and his primary platform is Mac with strong desire to make emacs better on Mac too out of the box, and he is a very capable programer, and also a sociable person. I think John will bring a lot good things to emacs. Thanks John.

Many emacs experts, use paredit, smartparen, ace-jump, expand-selection, and evil-mode, god-mode, hydra.
i don't use any of that. Just Xah Fly Keys
I openly challenge anyone to efficiency contest, in real time.
email me or tweet to me on social networks. We can setup a private video chat just to compare notes.
