Basics Of Sql-injections. - Critical Security.NET. Command line tricks for smart geeks. Everyone knows the answer to the question of life, the universe and everything is "42", but for the first time we can reveal the question. It is this: how many command-line tricks must a man memorise? You see, graphical user interfaces are all well and good, but when you want to get real work done it's time to switch to the terminal.
And so, we squeezed our brain cells, dug through dusty piles of old issues of Linux Format, and sat reflecting quietly over many a pint of ale, all with the goal of bringing you this: 42 awesome new command line tricks we think you ought to commit to memory. We've tried to include a few that are easier for our, er, less-experienced readers to enjoy, but we think even the most hardened Linux veteran will learn something new over the next 12,000 words. So, strap yourself in and get ready for command-line heaven: it's time to kick ass and chew bubble gum, and we're all out of gum...

How To Configure Remote Access To Your Ubuntu Desktop. Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 01/23/2008 This guide explains how you can enable a remote desktop on an Ubuntu desktop so that you can access and control it remotely. This makes sense for example if you have customers that are not very tech-savvy. If they have a problem, you can log in to their desktops without the need to drive to their location.
I will also show how to access the remote Ubuntu desktop from a Windows XP client and an Ubuntu client. I do not issue any guarantee that this will work for you! 1 Preliminary Note I have tested this on an Ubuntu 7.10 (Gutsy Gibbon) desktop. 2 Enabling The Remote Desktop We don't have to install anything to enable the remote desktop on Ubuntu.

1. INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between literally billions of people and is used as a tool for commerce, social interaction, and the exchange of an increasing amount of personal information, security has become a tremendously important issue for every user to deal with.
There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting health care information. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. As an aside, the AES selection process managed by NIST was very public. A digression: Who invented PKC?

Programming. Removing an object on a photo with GIMP. Tutorial to remove objects (or people) and restore the portion of the background they hide in a photo with the Resynthesizer plugin. An impressive video has been posted on Youtube to show how, with Photoshop, it is possible to delete objects in an image automatically, without any design work. The same can be done with The Gimp in fact and for longer (it is not impossible that the same algorithm has been reused). This plugin "re-synthesizes" the background" and rebuilds it from same elements on the photo. It can thus reconstruct the sky, lawn, or even more complex views, from a sample taken from the image. First, see the Resynthesizer tutorial to know the purpose of controls.
We will put in practice the commands using the same pictures that the Photoshop demonstration video. Using Resynthesizer in Script-Fu 1. 2. We want to remove the tree on the top left. 3.
