Link: Repair Scanned Documents With gscan2pdf
I had the pleasure last week of tracking down an article locked behind a digital paywall. It arrived through inter-library loan in the form of a book, all issues of the journal that year bound together. I felt a little disappointed as it meant I’d be left with lower quality scans. (You know what I’m talking about if you’ve ever placed a book on a copy machine.) I turned to the internet for a solution and discovered the tool gscan2pdf.

Link: How to convert Apache rewrites for nginx
Apache is still by far the most widely deployed HTTP server, according to the latest Netcraft web server survey, but nginx has been slowly, steadily gaining market share, thanks to its blazing speed. If you want to try a faster web server and move from Apache to nginx, you’ll probably have to change some of your websites’ configurations, starting with rewrite directives. To migrate rewrite rules from Apache to nginx, start with these tips and tricks.

We must confess that we are not as fond of the Linux command line as some Linux users — we’ll take a good GUI, and a mouse over a keyboard any time we can.

Link: How to Flash an SD Card for Raspberry Pi
The Raspberry Pi is an incredible little computer made up of a components and connectors on an unfeasibly small printed circuit board that is approximately the dimensions of a credit card. Depending upon your intended use, your Rasberry Pi may have a keyboard, monitor and mouse added. Regardless of your intended use, you are going to need an SD (Secure Digital) card on which to install an operating system.
This tutorial describes how to install an operating system onto an SD card for use in your Raspberry Pi.

Link: Autotrash – Purges files from your trash based on age and/or filename
Autotrash is a simple Python script which will purge files from your trash based on their age or the amount of free space left on the device. Using autotrash -d 30 will delete files which have been in the trash for more then 30 days. It uses the FreeDesktop.org Trash Info files included in the new GNOME system to find the correct files and the dates they where deleted.
Features:
Remove files that are older then a given number of days (see the -d option)
Purge older files to ensure a specific amount of disk space is free (see the –min-free option)
Check for remaining disk space, and only delete if you are running out (see the –max-free option)
Delete regex matching files first (see –delete-frist option)Install autotrash on ubuntu

Link: A Raspberry Pi File and Print Server
I was recently looking into the options to buy a living room “home server” to centralize certain services like file and print server, media server, etc.
It didn’t take me long to realize that for less money I could get a whole legion of small microcomputers that do the same work better and more securely; and use less energy while doing so.
This was of course the pretext to buy my first Raspberry Pi. A few more should follow… This article starts a little series explaining what I did and how I did it. Today, I will look at the first and simplest type of server …

There’s something exciting about crossing the boundary between the abstract world of software and the physical ‘real world’, and a relay driven from a GPIO pin seemed like a good example of this. Although a simple project, I still learned some new things about the Raspberry Pi while doing it.
