Files

First things first, I want to use ag to search through my project files. Coming from fzf, I like to have two bindings for this -- one that respects my projects .gitignore and one that does not. The latter is helpful if I want to examine a built file or look at a node_module dependency while working on my js project.

I use an alias for file_rec source to toggle the -u flag on ag. Now, <C-P> searches in my git files, and <C-O> searches everything.

" denite file search (c-p uses gitignore, c-o looks at everything)
map <C-P> :DeniteProjectDir -buffer-name=git -direction=top file_rec/git<CR>
map  :DeniteProjectDir -buffer-name=files -direction=top file_rec

Smart Caps Lock: Remap to Control AND Escape (Linux, Mac, Windows)

把 Caps Lock 變成智慧的 Control 以及 Escape ：

單獨輕按一下就是 Escape 。
若按下時同時按著其他鍵，就會是 Control 。

這應該是 Vim 和 Emacs 的最佳解了！(Emacs? Bash 的快捷鍵就是 Emacs 系列的)

Send Escape if you tap Caps Lock alone.

Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.
