How to Write-Protect USB Flash Drive

Many a time, it becomes necessary for us to write protect our USB flash drive so as to protect it from viruses and other malware programs. Because flash drives are so popular and most widely used to move data between computers, they are the prime target for attackers as a means to get infections spread around the computer world. Also, since USB drive is not a Read-Only Memory (ROM), the data inside it can easily be modified or deleted by malware programs.

Exiting Windows the Cool and Quick Way

Normally it takes a hell lot of time just Shutting down Windows, you have to move your mouse to the Start Button, click on it, move it again over Shut Down, click, then move it over the necessary option and click, then move the cursor over the OK button and once again (you guessed it) click.This whole process can be shortened by creating shortcuts on the Desktop which will shut down Windows at the click of a button. Start by creating a new shortcut( right click and select New> Shortcut). Then in the command line box, type (without the quotes.)

C++ - std::sort with a non-static compare method

Usually when you want to sort a std::vector or another container thats holds objects of a custom datatype, you just write a compare function that takes two such objects, does something to find out if one is less than the other, and returns true if it is. Then you pass the address of this function to std::sort and voila.

C++ - Bitmap Tutorial: Loading and Saving Bitmaps

1. Introduction

The windows bitmap file format (.bmp) is the most widely used image file format on windows (next to .jpg), and there are many occasions a program or game has to be able to load or save bitmaps ( raytracers and other non-realtime renderers should be able to save their output in .bmp format, games might have to load them as textures etc. ).
Unfortunately .bmp files are not as straightforward as for example .png image files and provide quite a problem for newbies since it's not that easy to figure out how to use them when without a library or API.

Two notes before we start:
1) In this tutorial we're dealing with 24 bit bmps only. But it shouldn't be hard to change the code to support other formats.
2) For clarity's sake i'm only showing the code important to the task at hand, with only minimal error checking. If you want to use this code in a real program, you should add some exception handling.

How to Bypass BIOS Passwords

BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS

Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:

Reinstall Linux Grub Bootloader After Windows Wipes it Out

If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu, Fedor or whatever flavor of linux you prefer.
Here’s the quick and easy way to re-enable Grub.
1) Boot with a Linux LiveCD
2) Open a Terminal and type in the following commands, noting that the first 2 commands will acquire permission to configure grub and put you into the grub “prompt”, and the next 3 commands will be executed there. Also note that hd0,0 implies the first hard drive and the first partition on that drive, which is where you probably installed grub to during installation. If not, then adjust accordingly.To do this easily, go “Computer Icon” on your desktop of “fedora” for example and count drives from 0 until reach the drive where installed grub.
