How to recover from a failing Kernel

Apr 292011

Or perhaps i should call this “Do you remember i was upgrading to Ubuntu 11.04 ?”.

Well something is gone bad and when i rebooted to start my new Xubuntu 11.04 i got:

error: cannot read the Linux header.
error: you need to load the kernel first.

  Failed to boot both default and fallback entries.

Press any key to continue...

During the upgrade, Ubuntu has removed all old Kernel but one, and so..i find myself without a way to boot my machine.

Fortunately I did a lot of experience with Gentoo in the past, that on this occasion was very useful to recover the system.

Tesseract-ocr: how to convert scanned documents into editable text on Ubuntu or Debian, Original article by Gabriele published on Gmstyle (italian blog)

I learned from the requests come via email, that some of my readers use Ubuntu (or Linux in general) to work and deal with graphics and publishing, who for his profession and who as a hobby. I draw inspiration from the request of a dear member of this little web space, which has given to me the input for this article, to make a bit of clarity about a subject that,for what I’ve saw around during my research on the Internet, seems to have created some difficulties for many people.

The argument i’m talking about is the OCR technology (Optical Character Recognition), that is a “technology ” that can recognize text characters from an image of paper documents previously digitized through the scanner and then transform this into an editable text. Continue reading »
