Hack Like a Pro: Linux Basics for the Aspiring Hacker, Part 21 (GRUB Bootloader)

Welcome back, my aspiring hackers! Many of you have installed Kali Linux as a virtual machine (VM) using VMware or VirtualBox, while others have installed Kali (or BackTrack) in a dual-boot system.

News: A DreamWorks Tablet Is Coming. What's Next, HBO GO Phones?

If I could think of one thing the world was missing, it would surely be more tablets.

How To: Start a Car After a Very, Very Long Time in Storage

My grandfather's brother won this car in a lottery during 1957. He had no driver's license, but his brothers used to give him a lift in it. From 1975 to 1996, the car was parked in my grandfather's brother's garage. My grandfather moved the car on a trailer in 1996 to his garage a few miles away, but it's been standing still there until this year when I rolled it out and started it up. This was the first time someone turned it on in 38 years!

How To: Put Your Samsung Galaxy Note 2 in Deep Sleep Mode to Save Battery Life

Newer smartphones are more power hungry than ever before, and the Samsung Galaxy Note 2 has a mighty appetite for amps that only Jenny Craig could possibly curb. On average, your Note 2 (or other Android device) lasts for what, a day, maybe two days before dying. Mine barely lasts 8 hours! This is thanks to all of the apps running in the background of your phone, even when you're not using them, eating through all of your CPU, leaving nothing but crumbs.

You can share a device with your family, kids, or s...

How To: Cut and Sand Your Micro-SIM into a Nano-SIM Card for Your New iPhone 5

Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

How To: Use implicit differentiation

Taking this formula 9x²+y²=9 your instructor shows you how to find the solution for the variable y. Finding a second derivative is no more difficult that finding the first derivative, you only have to do the problem equation through twice. The derivative of 9x² will be 18, of y² will be 2y [this is the same as 2(y), 2 x y or 2 * y]. The problem now goes -18x + 2y dy/dx=0. This equation is solved for dy/dx making the next step in the problem go -18x 18x+2y dy/dx=0-18x, 2y dy/dx= -18x. The next...
