Can't run Windows 8 virtual machine using VirtualBox (4.2.4) on Dell 610 machine :( Error message says: VT-x/AMD-V hardware acceleration is not available on your system. Certain guests (e.g. OS/2 and QN) require this feature and will fail to boot without it Looks like Win8 needs VT-x/AMD-V hardware to work.

I have a pretty old Eee PC 900 that have been running Arch Linux for awhile. I did an update lately and it borked it beyond my knowledge how to repair. So, I was thinking why not use Ubuntu minimal install? I am pretty familiar with Ubuntu/Debian distribution, fixing it should be much easier as I am familiar with the distro. As an aside I am planning to use it as a web server and i don't want to update the machine weekly to keep up with the latest Arch packages. Ubuntu 12.10 minimal installation is very easy now a days  It is as easy as installing Windows :). Anyway, I used a copy from  https://help.ubuntu.com/community/Installation/MinimalCD . Ok, I am still using a lot of Windows machine ;(, so burning it to USB flash I used unetbootin . Below are the sequence/options I have selected/or data supplied. Turn off Eee PC 900 Connect flash drive (flashed with Ubuntu mini iso using unetbootin) Turn of Eee PC 900, press ESC to view boot options Select "Install" fr...

Blogger client force closes in my Droid Razr Maxx, can't use it at all :(. This was observed with Blogger v2.0. Ok, reboot of the phone fixes it.

Remotely connecting to Linux securely in Android is like a walk in the park, ssh clients abound in Google Play Store. But ssh clients are not created alike. Some are designed with specific hardware in mind and for those who like to use physical keyboards, like Droid 3, you probably want to use all the keys. I have tried Terminal IDE, ConnectBot, Android Terminal Emulator but none of them work as I would have hoped. Like using ~, tab key for command line completion, display mc (Midnight Commander) properly. But one actually meet my need today, VX ConnectBot . In my understanding it is based on ConnectBot with changes to allow a much more pleasant experience using hardware keyboard. Try it for yourself, download from Google Play Store. Note: * Tested using Droid Razr Maxx using stock OS and Droid 3 using ICS.

Not sure if this is the right way to do it, searching the blogoshpere seems to indicate that this might be the case. Steps to change default port that Apache listens on: As good practice make a copy of the file ports.conf to somewhere safe. Like mkdir ~/bak cp /etc/apache2/ports.conf ~/bak Open and edit ports.conf, like sudo vim /etc/apache2/ports.conf . In Ubuntu 12.10, change Listen 80 to Listen 81 . This should be around line 9, of course change 81 to a value that you need. Restart Apache to enforce the changes, like sudo /etc/init.d/apache2 restart .

http://pinvoke.net/ is my goto location when I need to call native functions into C#. I just found out today that there is actually an alternative from Microsoft called P/Invoke Interop Assistant, head to the link below to get the binaries. http://clrinterop.codeplex.com/ http://clrinterop.codeplex.com/releases/view/14120

To check if a file exists on a remote site (say a web site), do the following: $: wget --spider https://dl.google.com/linux/direct/google-chrome-stable_current_i386.deb The above command checks if a stable version of Google Chrome exists in the remote location specified.
