Completely remove programs with Revo Uninstaller

Freeware application Revo Uninstaller makes removing programs from your computer—not just uninstalling, but removing all traces—a quick and painless process. So why would your use Revo Uninstaller rather than the default Add/Remove Programs dialog?

Well, for one, the default Add/Remove is notoriously slow at loading all of your installed apps; it also only runs the installer, which doesn't necessarily eradicate the program to your liking. Beyond that, though, Revo Uninstaller is feature-packed in ways you didn't even know you wanted.

cross-hair.pngOne of my favorite features is "Hunter Mode," which lets you drag a cross-hair onto any application—from the actual window to a system tray icon or shortcut. When you release the cross-hair, you can perform all of the uninstall tasks. For system tray icons, you can even tell the program to stop autostarting. The cross-hair is especially handy if a rogue application is running and you don't know what the hell it is (think cleaning crap from a friend or family member's computer).

Aside from the Uninstall features, Revo Uninstaller has a startup manager, which lets you tweak what apps start with Windows, and a few other handy tools. Granted, you can accomplish much of what Revo Uninstaller does without it, but I've never seen a program that does as much as Revo Uninstaller as easily as it does. This one's found a quick home among my must-haves.

What happens when you tell it to uninstall itself? He He !

Efficient String Permutation Program.

The following piece of a code is a very efficient use of recursion to find the possible permutation of a string.

public class Permutations {

public static void perm1(String s) { perm1("", s); }

private static void perm1(String prefix, String s) {
int N = s.length();
if (N == 0)
else {
for(int i = 0; i < N; i++){
perm1(prefix + s.charAt(i), s.substring(0, i) + s.substring(i+1, N));
public static void main(String[] args) {
String alphabet = "Test";
String elements = alphabet.substring(0, alphabet.length());

Debugging this code might prove to be a little difficult though but excellent logic though.

Find loops in a linked list.

There are several algorithms floating on the net to detect a cycle/loop in a linked list. The following code detects cycle in a linked list in time O(N) and space O(1).

/*Algorithm : P2 is moving through the list twice as fast as P1.
If the list is circular, it will eventually get around P1 and meet */

public boolean hasCycle()
DoubleNode p1,p2;
p1=p2=firstNode; //Start with the first loop

while (p2 != null) //If p2 reaches end of linked list, no cycle exists
{; //Move to next; //Move to 2 steps next
return true; //p1 and p2 met, so this means that there is a cycle
catch(NullPointerException npe)
//This means that p2 could not move forward
return false;

return false;

How to reverse a singly linked list in Java ?

Sometimes the solutions are not quite obvious. Search for an algorithm to reverse a singly linked list using Java and you wont find any good hits except for this code.

public void reverse()
Node currentNode, nextNode, loopNode;


while(nextNode != null)
{ = loopNode;
loopNode= currentNode;

first = currentNode; = loopNode;


This might not be a very intuitive solution at first sight but infact this is a very clever simulation of C/C++ pointers in Java. Credit goes to my wife for this fascinating algorithm.

Another version of this algorithm can be found here. This is a much improved and efficient way of doing this.

Add tabs to Windows desktop with Stick

Freeware app Stick adds tabs for RSS, calendar, explorer, notes, and the calculator to the Windows desktop. Stick tabs are highly customizable and can be relocated to any part of the screen. Stick leaves a light (10MB) memory footprint and opens Explorer, Calculator, and the calendar much faster than Windows on its own. By setting your tabs to remain on top and to auto-hide, you can have one-click access to some of your most frequently used apps without disturbing your desktop or existing apps. Stick also acts as a keyword launcher (Windows Key + Space) and has hotkeys baked in so you can access your tabs without the mouse. Stick ain't no Launchy, but its speed, light memory usage, and hotkeys make it well worth the college try. Stick is a free download for Windows only.

New Quicksilver for Windows app Skylight

Freeware application Skylight is a file and application launcher of the Quicksilver ilk, providing quick access to programs, files, and then some. Anyone who's spent much time with Quicksilver on the Mac knows what a huge productivity boost the wildly extensible Quicksilver can provide.  Skylight looks like the most promising Quicksilver-for-Windows app I've seen yet.  That's not to say there isn't a lot of room for improvement. Here's a few things I'd love to see from Skylight:


  • The ability to customize scanned folders
  • More plugins, of course! And more customization in general of folders and filetypes scanned.
  • It looks like Skylight is supposed to have folder browsing capabilities like Quicksilver, but so far it doesn't seem to be implemented. The documentation says navigation up and down a folder structure will use the arrow keys, and I'd love to see Skylight incorporate the backslash like Quicksilver uses to navigate up and down a folder structure.

At this point, I probably wouldn't recommend ditching Launchy in favor of Skylight—mostly because of Skylight's current lack of customization. However, if Skylight continues to develop in the same direction as its currently heading, it looks to be developing more quickly in the direction of a strong Quicksilver-like app for Windows than any alternative I've seen. Keep an eye on this one, folks. Skylight is free, Windows only, requires .NET 3.0.

Minimize Everything to Tray

Chances are that your taskbar is always cluttered and you hate it and you are helpless. MinimizeToTray Extension can help reducing Firefox and Thunderbird clutter but still, you might want to minimize other application to System Tray to reduce the clutter. There are some cool free application that allow you to do exactly this.

Windows users can save space on their Taskbar by downloading the nifty little program TrayIt. While viewing a maximized window, press CTRL as you minimize it on your taskbar. The program will no longer show up as a regular rectangle on the taskbar, rather, it will be a little icon in your tray. Just double click on the icon when you want to maximize the program again. Try TrayIt 

4t Tray Minimizer minimizes programs to your system tray, much like TrayIt. 4t Tray Minimizer, however, has many other features - such as the ability to 'hide windows' and to launch applications on the desktop through a menu in the system tray. 4t Tray Minimizer adds a 'hide window' and 'minimize to tray' button next to the minimize, close and restore/maximize buttons. 'Hide window' hides the window, not sending it to the tray, and the only way to restore it is to launch the main window of 4t Tray Minimizer. Minimize to Tray, meanwhile, simply minimizes it to the system tray. 4t Tray Minimizer is Windows only, and is available for download as both freeware and commercial software.
