Gnome-Entwickler Richard Hughes hat ein Colorimeter für TFT-Displays vorgestellt. Der USB-Farbsensor besteht aus nur wenigen Bauteilen, und sowohl die Hard- als auch die Firmware sowie die Client-Software wurden unter GPL veröffentlicht.
Just a list of 20 (now 28) tools for the command line. Some are little-known, some are just too useful to miss, some are pure obscure -- I hope you find something useful that you weren't aware of yet! Use your operating system's package manager to install most of them. (Thanks for the tips, everybody!)

RFDump is a backend GPL tool to directly interoperate with any RFID ISO-Reader to make the contents stored on RFID tags accessible. This makes the following types of audits possible:
* Test robustness of data-structures on the reader and the backend-application
* Proof-of-concept manipulations of RFID tag contents
* Clone / copy & paste User-Data stored on RFID tags
* Audit tag-security features
Hmm. I should mention that I dual boot with Windows sometimes, and in fact it's currently completely broken in there - Fn+F5 doesn't even show it (it shows the other two functions) and my Vodafone program can't turn it on. I tried leaving it on in Linux and then booting into Windows, to no avail.
I'm currently in the process of expanding my programming horizons to linux. In order to do that, it is important to have a good basic toolset on which you can rely on. and what is more basic then the IDE in which you write your code?
ZBar is an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39 and Interleaved 2 of 5.
This is a small application that can be fed the output video stream of a webcam, in which it can recognise and decode code-39 barcodes. It is simply a console application that is limited to parsing an input raw ppm stream, outputting the barcodes to the stdout.
How to remove new lines from files or pipe streams under Linux? This post contains simple examples that show how to use common Linux shell tools such as tr, awk/gawk, perl, sed and many others to delete new line characters. C and C++ source codes are also provided. They can be compiled into a binary tool that removes new lines. To get started, here is an example text file: days.txt. Lets have a look at its content by running the following command from shell.
The webcollage program pulls random image off of the World Wide Web and scatters them on the root window. One satisfied customer described it as "a nonstop pop culture brainbath." This program finds its images by doing random web searches, and extracting images from the returned pages.
