Linux has always been about the sharing of knowledge and the freedom to
look at the source code, the freedom to learn from it and to change it
according to your needs, the freedom to use it where and in every way
At the moment it seems however that more and more people try to enter
the Linux arena who not only know nothing about morals and good manners
but also don't care the least about the spirit of Linux. Money is all
Are the times gone when programmers happily wrote their code and met
during small conferences while now the people in suits are taking over
not knowing better than fighting about Linux in the court room?
The world is constantly changing and so is Linux. If it is for good or
for bad only the future will show but as long as there are still people
out there living its spirit and willing to make Linux the best possible
operating system I am in good hopes that its original spirit will still
live on after those people in suits have long left the stage again!
In this article we describe how to build an autonomous robot with a
microcontroller that will always try to walk to the brightest spot.
The LinuxFocus Tip
If you own a digital camera then you probably had already the problem
that you wanted to print 50 or more images on photo paper. You did
not what to print them with 1 image per page instead you want them
smaller: 2 images or 4 images per A4 (or US Letter) page. It's a lot of
work to go to an image manipulation program such as Gimp and combine
manually 4 images
onto one page in order to print them. ImageMagick (www.imagemagick.org) and
its "montage" command can do this for you automatically:
Now you just print result.jpg. ImageMagick can also generate postscript
directly but the quality is not as good as the one generated by Gimp.
It is therefore better to print result.jpg from Gimp.
Here is a perl script called combine4images (download: combine4images.txt)
that can run over a directory and combine hundreds of images into
4 images per page and generate combined images in landscape and portrait
[Note: just in case that ImageMagick changes the API: This
has been tested with ImageMagick version 5.4.3]
