Password Cracker
Passwords are perhaps the weakest links in the cyber-security chain; if they're complex enough to be secure, you probably won't be able to remember them. Add the fact that every other site seems to require a password, and it's easy to see why far too many people end up using one or two simple passwords that are easy to remember, and easy to crack, too. You can write your passwords down on a piece of paper that you can look for and fail to find when you need it, or you can download and install G&G's Password Cracker. It's a tiny, free, totally portable utility that can recover lost passwords from applications.
Password Cracker downloads as a compressed file but runs as soon as you click the unzipped program file. The tool's interface is a tiny dialog, about the size of the average error message, with two text fields, labeled Test and View, and four buttons: Enable, Options, About, and Help. Other than some links to the program's Web site and some of the developer's other wares, that's it. However, the button's labels describe their functions clearly enough, so we started by checking the options, which are minimal, with check boxes to recover passwords in Internet Express or all of Windows. We checked the latter, opened a browser window, and navigated to a site that required a password log-in. We clicked Enable, hovered the mouse cursor over the password field (as delineated by asterisks), and Password Cracker displayed the alphanumeric password in the View field. We repeated the process with a Windows program that requires a log-on to open, with the similar success. The always-on-top option is handy since it keeps the little dialog from getting lost in a stack of open windows.
Build Your Own GameBoy-Sized Handheld with a BeagleBone
The
GameBoy is a classic piece of equipment, and if you want to live those
glory days with a bit more power, blogger Max Thrun shows off how to
turn a BeagleBone Black into a handheld device that can play a wide
range of games.
As you'd
probably expect, this isn't exactly a simple project, but it's doable if
you know some electronics basics. You'll need to do a lot of soldering,
as well as making your own circuits. You'll also need to send off to
have the case built for you. Once you're done, you'll have a tiny
handheld system that can play NES, GameBoy, Sega, and more. The thing's
even smaller than a GameBoy.
