Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop

Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop

Command-Shift-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop

Command-Control-Shift-3: Take a screenshot of the screen, and save it to the clipboard

Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard

Command-Control-Shift-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard

In Leopard and later, the following keys can be held down while selecting an area (via Command-Shift-4 or Command-Control-Shift-4):

Space, to lock the size of the selected region and instead move it when the mouse moves

Shift, to resize only one edge of the selected region

Option, to resize the selected region with its center as the anchor point

OS X 10.8 Mountain Lion bootable USB (without MAC)

Download the raw file from here . How to use: 1 - Copy the .raw file to an USB stick using SUSE Studio Image Writer . If you have error during copy, eject and re-connect the pen drive. When Windows asks if you want to format it, cancel and run Image Writer again. If the problem persists, disable your anti-virus software, it may be blocking raw write to the drive. Another Image Writer for Windows, if SUSE doesn't work https://launchpad.net/win32-image-writer/+download 2 - Boot the USB drive and install. If you need, type boot options , for example: -v (verbose boot) [default] -x (safe) -s (single user) GraphicsEnabler=yes (enable graphics card drivers) [default] USBBusFix=yes (fix problems with USB devices) npci=0x2000 (use if boot stops at "PCI configuration begin") cpus=1 If you need, use TransMac to remove kexts which are causing problems (System/Library/Extensions) and use the flag -f (ignore caches) at boot, or remove /System/Libra...

JavaScript - Singleton Pattern

The singleton design pattern is probably the simplest and most common pattern in JavaScript. So why should you use the singleton pattern? Encapsulation of members & functions Creates its own Namespace A singleton is a single instance object Encourages code reuse Improves readability because you can logically organise your code The point of a singleton is to only have one instance. A shopping cart is a good example of something that you may want only a single instance of at one time. The simplest form of Singleton is an object literal. This loose form of Singleton cannot be instantiated. All of the members are now accessible through the Singleton variable, accessible through dot notation. var myCart = { self: this , totalCost: 0, totalQty: 0, cart: {}, getCart: function (){ }, updateCart: function (){ } }; alert( "Total cost: ...

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.
