In some extremely rare cases you end up pushing data to the repo with the wrong credentials. If you are the only author and you’re as picky as I am, it can be corrected easily:

git filter-branch -f --env-filter
"GIT_AUTHOR_NAME='Stan Smith';
git push --force

In the case of there being multiple people working on a project, you may want to use the following gist posted by anonymous: (again, followed by git push --force).

I recently discovered an incredibly useful function - you can look up man pages for keywords by pressing K (read: Shift + k) in normal mode when cursor is over the word you need to look up.

It works with any shell or programming language keywords, as long as vim recognizes the filetype.

I find the default cygwin color palette to be a bit ugly, so here’s one that has softer colors. Add the following lines to your .minttyrc and restart cygwin in order to apply changes.

ForegroundColour = 131, 148, 150
BackgroundColour =   0,   0,   0
CursorColour     = 220,  50,  47

Black            =   7,  54,  66
BoldBlack        =   0,  43,  54
Red              = 220,  50,  47
BoldRed          = 203,  75,  22
Green            =   0, 200, 132
BoldGreen        =   0, 200, 132
Yellow           = 204, 204, 102
BoldYellow       = 204, 204, 102
Blue             = 102, 153, 204
BoldBlue         = 102, 153, 204
Magenta          = 211,  54, 130
BoldMagenta      = 108, 113, 196
Cyan             =  42, 161, 152
BoldCyan         = 147, 161, 161
White            = 238, 232, 213
BoldWhite        = 253, 246, 227

Setting up Ruby on Rails with MongoDB on a Windows machine.

You need to have cygwin installed with ruby and git packages (obviously you may want to have more).

The following commands are executed in the cygwin prompt:

git clone git://
cd rubygems/
ruby setup.rb
gem install rails

Go to the MongoDB website and download Windows binaries: Extract the content of the bin/ directory to C:\cygwin\usr\local\bin.

Create a directory for the db files (the default MongoDB db files directory is C:\datadb):

cd /cygdrive/c
mkdir data
mkdir data/db

Done! Both mongo and rails are in your cygwin’s path now, feel free to tweak it as you see fit.

I’ve been giving preference to a keyboard over mouse since I discovered vim for myself, as it’s a faster and more convenient way to go. I am a Chrome user and recently I found an amazing plugin: Vimium.

It does exactly what the name suggests, allowing you to use vim-like commands in your browser. You can freely move, switch between tabs, work with forms and click links using familiar vim key bindings.

A two minute long introductory video explains basic commands and you’re all set! I’ve been using Vimium for over a week now, an amusing experience which allows you to throw your mouse in a dark corner (well, not exactly: Vimium still has some issues with over-bloated ajax pages, not to mention Flash and other nasty stuff).
