Use meld as git diff gui viewer

Meld is a popular diff viewer in linux (gnome). It is extremely light weight. UI is very similar to WinDiff. Although it is not comprehensively robust yet, It is still a great help for people like me, handicapped to read huge diffs in command line.

Git is awesome when it comes to managing version control, esp in command line. However, while committing, you would want to check what changes are going in. git gives git-diff for this purpose. Spitting out a (unified) diff format text for showing changes. But reading this could be cumbersome at times. To visually inspect git diff, you can use the latest version of meld. The version that comes with debian or ubuntu 1.1.5 lacks git support. You need to build the latest meld (I got 1.2.1) from source. Here is how you can do it.
  • resolve dependencies:
    sudo apt-get install pyorbit pygtk gnome-python intltool
  • Get the source from here (opens new window).
  • Extract the archive.
  • In the exploded directory, run make.
  • It makes an executable meld
  • Run meld path/to/git-project
  • That's it, if there are any modified files, it will display the changes.
meld and git
As an earlier alternative, if you have KDE or prefer to use kompare, You can pipe this to kompare to visually see the changes.
git diff . | kompare -o -

I have tried using egit for eclipse. It sure is good for many features (commit, track, reource history, pull et al) but misses the "compare with base version" feature as in svn. Meld fills in that gap.

Javascript: Convert Strings to Binary (and representing in a nerdy way!)

I follow those GoogleDevelopers Videos. Sometime back, in one of the presentations on GoogleIO, there was this interesting string of dots at the bottom of each page of the presentation. They looked like random big and small dots. A similar bunch of dots were also on the T-shirt of a presenter was wearing in another presentation. While it seemed something in the pattern, I could not find what it was. Finally, another presenter cleared the matter that those dots are just binary representation of "GOOGLEIO" (So much for advertizing Google IO, Impressive!).

So I wanna do it. Takes me back to days of those DSP classes at school. Nerdy me had to churn some old brain cells. I remember those first programming language classes in Pascal and C when you were asked to do fibonacci series and converting a binary string to ascii codes. That *experience* came handy here: Check it out!
