This all-in-one is supposed to work out of the box in Ubuntu 9.10 but the scanner didn't work when I plugged it in. In fact, scanimage -L didn't even list it.

Karmic comes with hplip 3.9.8 which should support the f4440. I tried installing the newest version of hplip from http://hplipopensource.com (3.9.12 at the time of writing this) but the script kept aborting due to an error when it was running the make command. So here is what I did to get the all-in-one working.

NTFS Undelete: Recover deleted files

sudo apt-get install ntfsprogs

NTFS Undelete is free and open source software that allows you to recover deleted files. It recovers files directly from hard drive, and it will work even if you empty Recycle Bin.
Before downloading NTFS Undelete, please consider the following:

When you delete a file, its content physically remains intact on the media, but the occupied space becomes marked as free. Next file saved to the disk may overwrite the contents of the deleted file.

It is very important to make sure that no application writes to the drive or partition where deleted file is located since every new file (even a small one) may overwrite the deleted file.

This how-to is based on a German wiki, the man page of randr and some own experiments. It addresses some projector detection and configuration problems in Karmic:

This is an aspect of FOSS that is regaining some measure of interest: for years, it was considered that writing production-ready FOSS meant lean and mean software. However, recent events have shown that, in the case of the Linux kernel, this is no longer exactly true: performance is dropping slowly yet steadily.

How come?

In this video I demonstrate how you can easily encrypt a flash drive to protect you sensitive data from being accessed by others. This method can also be used to encrypt other storage devices such as flash media, internal and external hard drives.

NOTICE: You might have to restart your computer once you encrypt the drive if you encounter problems mounting it.

At the Gran Canaria Open Desktop Summit in July 2009, the Open-PC project was announced. The statement said the project aimed to “cooperatively design a Free Software based computer by and for the community”. Further this PC would use only hardware for which there are free software drivers available. This would be a PC with the minimal compromise required for running a free desktop. In January 2010 the project announced the launch of its first product.

Oh dear. After the debacle with Microsoft Poland’s apparent racist photoshopping, Microsoft China went and got the company in hot water for allegedly “stealing” code. Yes you read that right: Microsoft and wholesale “theft” of code from another website. Of course it’s not “theft” it’s copyright infringement but tomayto/tomarto. Microsoft confessed blaming a vendor they had worked with. No surprise really but the damage to their name may have already been done. There’s more to discuss here than Microsoft’s already tarnished reputation though. The issue raises some important points in favour of free software and points to why more if not all code should benefit from free licencing.
