Using libsane and tesseract, you can scan from an ADF (or non ADF) scanner in Ubuntu 7.10 to a PDF and OCR’ed text document with a few easy steps.
First we need to make sure we have the necessary packages installed.
apt-get install tesseract-ocr sane-utils

Just did a stupid thing and deleted a whole tree of file on a windows partition. Never fear…ntfsundelete is here.
sudo ntfsundelete -u -d /destination/directory -f -m *.jpg /dev/sda1
Run without the -u option and -d options to show what can be recovered.
On ubuntu/debian to install it do:
apt-get install ntfsprogs
I am making the plunge to get more informed with how to use PostGIS. It is pretty impressive so far. Here is a quick tutorial which shows you how to get started and loading in a shapefile to play around with some fun SQL querying. I assume a basic understanding of the linux command line and some basic SQL skills.
To get started in ubuntu 7.04 (should work in 7.10 and debian too):
$ sudo apt-get install postgis postgresql-8.1-postgisNext we’ll start setting up the PostGIS environment.

While ITA Software doesn’t allow you to purchase directly from their flight search, they do provide a nice airfare search and grid view where you can see mapped out in time how much of the day the flight and associated layovers will take. Pretty neat.
Synergy is a network KVM. It is great if you have multiple computers. I have a setup with a Powerbook, WinXP and Ubuntu Laptop all controlled by the same keyboard and mouse (across four screens) merged together into one desktop. It is a beautiful thing… Some simple config examples after the jump.
Another attempt at showcasing an interesting Debian package each day. They have already shown one of my favorites along with something I didn’t know was out there. python-scipy is great and has helped me produce the spectrogram I posted about a few weeks ago. And scribus looks like it will be an interesting application to explore further…heads off typing apt-get install scribus.
More LaTex fun. I realized I could create both a CV and a Resume using LaTex by separating out the sections (education, publications, work experience, awards) into individual files. LaTex has an \input{filename} function which is useful for splitting large documents up. It just inputs whatever text is in that file like you had typed it in the main file. Once I break up the parts, such as education, publications, work experience into different files I can create an uber document that references things appropriate for the CV, and another referencing only those appropriate for the resume. Then I only need to edit the appropriate section file and it updates both, yay LaTex.
