By | April 28, 2011 | 4 Comments
I’ll admit up front – it’s embarrassingly late for me to have discovered screen. Friends and coworkers have been suggesting it to me for years, but it wasn’t until recently that I had a concrete need for it. Now I wish I’d had it all along. In short, screen gives you the equivalent of the “workspaces” you find in Gnome, KDE, and other desktop environments, but for the command line. It may not sound like much, but like the graphical equivalent, you begin to see the power after a few uses. Today we’re going to cover some screen basics useful for your home desktop but especially useful if you use remote access tools like SSH.

If you’re a Linux (or even Mac) user, and you’ve never toyed with your shell prompt, you might not realize just how useful a good prompt can be. Sure, it can show your user and host names, and perhaps the current directory, but a really good prompt can do a whole lot more. Those who spend a LOT of time in the terminal might even want to take it a step further and move into a custom semi-graphical shell with all kinds of bells and whistles.

How to Make Your iPhone Secure After the Jailbreak
By | July 26, 2010 |
Let me start this article by telling you about a person who was successful in attacking the vulnerabilities of phones on T-mobile Netherlands last year. There was not really a grave malicious intent on the side of the hacker except that he just wanted the people–whose iPhones were hacked–to know how vulnerable their gadgets were and he wanted them to pay 5 Euros to gain security for their iPhones.

However, once your iPhone is jailbroken, it will become vulnerable and less secure; you will need to take extra measure to retain its security.
