Malicious people don’t target big and corporate wireless networks only. If you have a Wi-Fi network at home or in a small office, your network might be attractive also. Malicious people might consider using unprotected and weak protected networks as hubs for malicious and illegal activities. By using an unprotected or weak protected wireless network, they can attack credit cards systems and netbanks from your wireless network and then all the illegal activities seems to originate from your IP address and your home or small office.
Therefore, all wireless networks should be protected with encryption.
Minimum Protection
- Use WPA or WPA2 encryption (not WEP encryption, it is proven to be unsecure and weak)
- If your wireless network devices do not support WPA or WPA2, then use WEP with minimum 128 Bit, enable mac address filtering (available in most SOHO routers), and use VPN-based encryption whenever it is possible.

Many people are unaware of the fact that it is possible to decompile and disassemble almost all types of Windows Exe-files.
What is a Decompiler
A decompiler is the name given to a computer program that performs the reverse operation to that of a compiler. That is, it translates a file containing information at a relatively low level of abstraction (usually designed to be computer readable rather than human readable) into a form having a higher level of abstraction (usually designed to be human readable).
Free and Open Source Decompilers for Windows
REC 2.1 – Reverse Engineering Compiler
REC is a portable reverse engineering compiler, or decompiler.
It reads an executable file, and attempts to produce a C-like representation of the code and data used to build the executable file.
It is portable because it has been designed to read files produced for many different targets, and it has been compiled on several host systems.
RecStudio offers a modern user interface to REC’s interactive mode.
A command line version is available for Linux and Solaris hosts.

· Tags: kernel, LTS, Lucid Lynx, Ubuntu, Ubuntu 10.04
Ubuntu 10.04 Alpha 2 is available and comes with Linux kernel 2.6.32, KDE 4.4 RC1 and a significant faster boot process. The release is a “alpha” release, which means that it is not fully developed and therefore may contain errors and other obst. The final version of Ubuntu 10.04 LTS it planned to be released on the 29 April 2010.
Really cool stuff
- PiTiVi included as default. PiTiVi is considered the most intuitive and featureful movie editor for the Linux desktop.
- The boot process. The goal is to reach 10 seconds for booting with 10.04 aka Lucid. The adoption of Upstart is one of the techniques to make the goal come true.
- Hal removal. The removal of the hal package makes Ubuntu faster to boot and faster to resume from suspend.
- Kernel 2.6.32. The new kernel means 3D support for newer Radeon graphics chips, better use of power saving features offered by the latest hardware and numerous enhancements to KVM and Btrfs are some of the outstanding items among the many thousands of changes undertaken for the latest kernel version. Various other improvements should also make Linux 2.6.32 more reactive and as a result, feel faster.

I experienced recently that I was unable to hit and click in flash based application using the mouse, which meant that I was forced to use the keyboard to navigate in all flash application – not a good user experience and very annoying. Adobe Flash does simply not register any mouse clicks (e.g. on YouTube, Google Analytics, etc.).
However I have researched on the bug, actually it was quite difficult to find anyone, who had experienced problem and reported it, also because the problem is hard to describe consistently. This fact was also clear, when I read the Ubuntu bug report.
The descriptions of the problem varies a lot: “Clicking on items in Flash player does nothing”, “I Cannot Click On Flash In Ubuntu”, “Flash does not register any clicks”, and “flash does not recognise mouse clicks”.
Solution
- Hit ALT+F2 and enter
- gksudo gedit /usr/lib/nspluginwrapper/i386/linux/npviewer
- add the following line BEFORE the last line of text
- export GDK_NATIVE_WINDOWS=1
- Save.
- Restart any applications using flash

Ruby on Rails – what the f…
Ruby on Rails, often shortened to Rails or RoR, is an open source web application framework for the Ruby programming language. It is intended to be used with an Agile development methodology that is used by web developers for rapid development.
Ruby on Rails is often installed using RubyGems, a package manager, which is included with Ruby. Many Linux distributions also support installation of Rails and its dependencies through their native package management system, anyway no matter the installation technique, installing Ruby on Rails on a Debian or Ubuntu distribution is plain sailing and very easy.
Installing Ruby on Rails using RubyGems
Install Ruby and RubyGems
sudo aptitude install ruby rubygems
As I wrote this post, there was a nasty bug in the Rails dependency notation for Rack, which means you’ll need to install version 1.0.1 of Rack instead of the default version, which is as of now version 1.1.0.
Install Rails
sudo gem install rack --version 1.0.1
sudo gem install rails
That’s all. You are done.
Installing Ruby on Rails using apt-get or aptitude
Install Ruby on Rails
sudo aptitude install rails
That’s all. You are done.
