Meld: Comparison Tool

Meld is a visual diff and merge tool targeted at developers. Meld helps you compare files, directories, and version controlled projects. It provides two- and three-way comparison of both files and directories, and has support for many popular version control systems.

Meld helps you review code changes and understand patches. It might even help you to figure out what is going on in that merge you keep avoiding.


  • Two- and three-way comparison between files and directories

  • Comparisons update as you type

  • Visualisations make it easier to compare your files

  • Actions on diff chunks make for easier merges

  • Supports Git, Bazaar, Mercurial, Subversion, etc.

File comparison

  • Edit files in-place, and your comparison updates on-the-fly

  • Perform two- and three-way diffs and merges

  • Easily navigate between differences and conflicts

  • Visualise global and local differences with insertions, changes and conflicts marked

  • Use the built-in regex text filtering to ignore uninteresting differences

  • Syntax highlighting (with optional gtksourceview)

Directory comparison

  • Compare two or three directories file-by-file, showing new, missing, and altered files

  • Directly open file comparisons of any conflicting or differing files

  • Filter out files or directories to avoid seeing spurious differences

  • Simple file management is also available

Version control

  • Meld supports many version control systems, including Git, Mercurial, Bazaar and SVN

  • Launch file comparisons to check what changes were made, before you commit

  • View file versioning statuses

  • Simple version control actions are also available (i.e., commit/update/add/remove/delete files)

Getting it

Meld is packaged for just about every Linux and Unix distribution, including Fedora, Ubuntu, and Suse. You should get Meld from your distribution's installer unless you want the absolute latest version. Also available on Ubuntu Software Center.

Meld does work on OS X and Windows, but there are no all-in-one packages for those systems available at the moment. On OS X, Meld is available from MacPorts or Fink. There are some notes available on how to get Meld running on Windows.

Ubuntu: Access a usb flash drive from the terminal

    1. Find what the drive is called You'll need to know what the drive is called to mount it. To do that fire off: sudo fdisk -l You're looking for a partition that should look something like:   /dev/sdb1 . Remember what it's called. 2. Create a mount point Create a new directory in   /media   so you can mount the drive onto the filesystem: sudo mkdir /media/usb 3. Mount! sudo mount /dev/sdb1 /media/usb When you're done, just fire off: sudo umount /media/usb Source: StackOverflow

Java: Use BigInteger in for-loop

In my previous post , I mentioned a way to handle large integers by using BigInteger. Now I'm going to provide a very important usage of it. We often use for-loop. So here is the way to use it: Ordinary integers: for(int i = 1; i <= n; i++) {  //Task to do } BigInteger: for (BigInteger bi = BigInteger.valueOf(1);                 bi.compareTo(n) <= 0;                 bi = bi.add(BigInteger.ONE)) { //Task to do } here n is a BigInteger variable.

Karabiner: Mouse/keyboard customizer for OS X

For beginners, or the one who migrated from Windows environment, Natural Gestures (Scrolling and Swiping) might be bit confusing. But, once you get familiarized with them, it may feel like "What was I doing, all those days?". It all changed, when I connected external mouse to my Macbook. When you start using that WHEEL, you will be confused. Luckily there is a setting for mouse, to change scroll behavior (natural or the other way). But, here's the catch. If you toggle that setting, it also toggles the same for TRACKPAD!!!!! I've seen that many people were freaked out and even raised BUG report to Apple. But, all those reports were closed, saying that is not a bug, but intentional feature!!! For those, who can't leave with such one-sided settings, here is a simple util, which came to my rescue: Karabiner It's simple, powerful and stable mouse/keyboard customizer for OSX.
