using mypaint on Linux

Here is description of mypaint.

Mypaint is a fast and easy/simple painter app focused on the painter, so you can only focus on the art and not the program itself. Currently MyPaint does not have a layer system, also mypaint is using pygtk with C extensions.

One of the interesting feature is that the width of the brush increse’s with the speed of the stroke.

My personal experience with the application was that the appllication does not have too many functionalities but is really very easy to use. Just select the brush and use it after invoking it. Here are some examples of the kind of effects that you can see with mypaint.

Scripts to create logins from bash command – for creating multiple accounts

Heres the script:

cat «EOF > login.sh
for i in  `cat logins` ; do
login=`echo ”$i”|awk -F”:” '{print $2}’`;
comment=”`echo ”$i”|awk -F”:” '{print $1}’`”;
gr=”`echo ”$i”|awk -F”:” '{print $3}’`”;
echo ”login –» $login –Comment –» $comment  –Group –»$gr  –”;
echo ”useradd -c ”$comment” -d /export/home/$login -m -g $gr -s /bin/bash $login”
useradd -c ”$comment” -d /export/home/$login -m -g $gr -s /bin/bash $login
done

You would need to create file called logins to store the comment, login name and the group. The group must have already been created. Here is an example of the file:

How To Run Subscriber-Only Competitions on Your Blog

A Guest Post by David Cleland from TotalApps.

In 2006 I proudly started my first blog, DigMo! It was <a class="zem_slink freebase/guid/9202a8c04000641f800000000003ac3a" title="Technology" rel="wikinvest" href="http://www.wikinvest.com/industry/Technology">technology, it was creativity, it was music and it was <a class="zem_slink freebase/guid/9202a8c04000641f80000000000141ab" title="Education" rel="wikipedia" href="http://en.wikipedia.org/wiki/Education">education. Despite it being a bit of blog soup I was pleased at how quick the site grew but within a few years it reached a critical point beyond which I really couldn’t get the traffic to grow. The site was frankly far too general to appeal to a specific community.

The best in command line xml: XMLStarlet

<a href="http://bashcurescancer.com/the-best-in-command-line-xml-xmlstarlet.html">Quite some time ago I wrote about using xsltproc to process xml on the command line. Thank fully someone pointed out XMLStarlet.? I now use XMLStarlet almost every day.? I work with a variety of REST based API&#8217;s gather information. XMLStartlet along with a simple for loop or xargs gives …

If you are on fedora then you can use xmlstarlet in the following way. First install the package:

Verify all the paths in the PATH directory

Here is the command to test that all the directories in your path actually exist.

(<a class="zem_slink freebase/en/internal_field_separator" title="Internal field separator" rel="wikipedia" href="http://en.wikipedia.org/wiki/Internal_field_separator">IFS=:;for p in $PATH; do test -d $p || echo $p; done)

And the explanation :

Set the IFS to &#8221;:&#8221;

now we loop through the PATH variable

and test all the directories with &#8221;test -d&#8221;

Here is another version without IFS:

for i in ${PATH//:/ };do test  -d $i || echo $i;done
