Source tagging is very powerful source code navigation system, it beats any state of the art IDE. If you are using Emacs, Vim and TextMate then you can use source tagging for navigation. Here are the few simple steps to do it.
Step 1. Install ctags in your system. For mac
$ sudo port install ctags
Step 2. Create A tag file
$ cd /Users/username/Workspace/rails-project $ ctags -e -a –Ruby-kinds=+f -o TAGS -R app/ lib/ config/
It is best to add this in crontab for this around 11:30am
Step 3.1 emacs
M-. Follow a tag M-* Jump back to source.
Step 3.2 vim
just add this in your ~/.vimrc
set tags=TAGS;/
Once this is done you can navigate to source of tag by using.
C-] – go to definition C-T – Jump back from the definition. C-W C-] – Open the definition in a horizontal split
Hope you will be able to use this awesome feature.
C is ctrl
M is Meta/Alt/Ecs

How to prevent googlebot following links in gmail messages? Well bad news is “Googlebot is following links sent to subscribers of a mailing list by email and it is causing those subscribers to receive an unsubscribe meesage or a added download from the list or server”.
Bigger Bad news is that age old trick will NOT work here, we can not solve this simply by adding
Best way in my opinion is to reject download count based on the user agent. Which is Googlebot in case of Google Crawler.

I mostly work on Terminal or Emacs buffer. I love emacs. Significant part of my work involves searching for a piece of code. Occur mode is similar to grep-find and find-grep. Just that I only search for the buffers which are open.

I am an ancient user of Gnu Screen. I am the one who will suggest new users use these better tools for servers. Gnu Screen is an excellent tool, but It is tough to configure and learn.
Recently I found a replacement. The Tmux!
Tmux is very easy to use. The best part is the shortcuts. 🙂
To install it in mac do
$ brew install tmux
on ubuntu
$ sudo apt-get install tmux
You can put your setting in ~/.tmux.conf
# set -g default-terminal "xterm-color" set -g terminal-overrides 'xterm*:smcup@:rmcup@'
This should be enough to get you started. Google for Tmux cheat sheet to know popular shortcuts. Here is one of them. http://cheat.errtheblog.com/s/tmux

Can your RoR editor run a web server inside itself, then capture the errors and hop to the error line in code.
Well Emacs with Rinari and ruby mode can do magic. You should checkout Emacs Wiki.

Firefox Sync. formally weave. I always wanted that I can continue my Firefox session from one place to anther. You don’t need to save password, you don’t have to save you history through Google Toolbar. You wont need bookmark addons. This is simply great. How many times did you left your computer at work on/hibernated because you thought you will loose your tabs(currently open sites). Sync currently supports continuous synchronization of your bookmarks, browsing history, saved passwords and tabs.
Main Features of Sync are:
As they say:
The Weave Sync add-on lets you securely take your Firefox experience with you to all your Firefox browsers. You can now surf the Web on your PC, get up and go, and have everything waiting for you on your phone: your history, open tabs, bookmarks, the Awesome Bar – just as you had left it.
Check out yourself from here. Get Sync for you too from here. Manage your account from here.
