Debian Developer Database Statistics
I am currently writing a paper for school with the title "Free and OpenSource Software in Switzerland", therefore i am interested in the FOSS community here in Switzerland. So i decided to make some statistic out of the Debian Developer Database, below is my ruby script for that purpose. It basically just queries the webinterface via https and then parses the results and makes some statistics. I plan to set this number in relation to the population of the corresponding countries.
#!/usr/bin/env ruby
# requires libopenssl-ruby1.8
require 'net/https'
class DDDB #Debian Developer Database
private_class_method :new
public
def self.get_developer_count(country = 'any')
html = get_html_for_country(country)
if html =~ /Number of entries matched: <b>([0-9]+)</b>/
return $1.to_i
end
return 0;
end
def self.get_developers(country = 'any')
q = '<font size=+1>(?:<a href="(.*?)">)?(.*?)?(?:</a>)?'
q+= '</font> (uid=.*?login:</b></td><td> '
q+= '<a href="mailto:([a-z0-9.@]+)"'
html = get_html_for_country(country)
html.scan /#{q}/m
end
def self.get_countries
http = Net::HTTP.new("db.debian.org", 443)
http.use_ssl = true
http.start { |http|
res = http.get('/')
res.body.scan /<option value="([a-z]{2})">(.*$)/
}
end
private
@@data = {}
def self.get_html_for_country(country)
if !@@data.has_key? country
@@data[country] = get_html_for_query(
"country=#{country == 'any' ? '' : country}"
)
end
@@data[country];
end
def self.get_html_for_query(query)
http = Net::HTTP.new("db.debian.org", 443)
http.use_ssl = true
http.start { |http|
res = http.post(
'/search.cgi',
"#{query}&dosearch=Search..."
)
return res.body
}
end
end
total = 0
data = {}
DDDB.get_countries().each do |code,country|
count = DDDB.get_developer_count(code)
if count > 0
data[code] = { 'country' => country, 'count' => count }
total += count
end
end
print "Total Debian developers: ", DDDB.get_developer_count(), "n"
print "Total Debian developers with country specified: ", total, "n"
data.each_value do |entry|
print entry['country'].ljust(35), entry['count'].to_s.rjust(5),' ',
"%02.2f%" % (entry['count'].to_f*100/total), "n"
end
exit 0
DDDB.get_developers('ch').each { |www,name,mail|
print name.ljust(35),(" <"+mail+"> ").ljust(35)
print www if !www.nil?
print "n"
}Oh well after having written the above script, i actually found out that i simply could have queried the ldap directory directly. Sigh.
Thanks SUN for open sourcing Java
It would like to thank everyone who was involved in the open sourcing of Java, by choosing the GNU GPLv2 you made the right decision. Thanks all the Classpath and Kaffe hackers for their effort in building a free Java. Hopefully you will join the SUN engineers and create a whole new community.
Here is a quote from RMS which summarizes it quite nicely.
This is a great day for the free and open source software community.

Evaluating Free Software wxWidgets GUI Builders | Designers [Update]
I am currently *trying* to write a cross platform gui frontend for qemu. I have chosen to use the C++ toolkit wxWidgets, mostly because it is written in C++ and therefore object oriented, other advantages are that on linux it uses gtk+ and it has good support for M$ Windows.
Since i don't want to mess around with basic things like the placement of the various gui elements, i looked around for a wxWidgets capable RAD tool. Below is a list with what i found so far.
After a _short_ evaluation my first impression is that wxglade is not quite there yet feature wise. wxDev-C++ is impressive but depends on Dev-C++ and is therefore only available on Windows. wxFormBuilder seems to be cross platform can generate both xml resource files and C++ source code which satisfies my needs.
So right know i think wxFormBuilder is my favorite but that could change once i start using it for a longer time.
Update
I found wxGuiBuilder
which is quite neat, the main idea is to represent the GUI with a few simple relatively easy recognizable ascii symbols. The advantage is that there is no XML and no IDE needed in order to build a good gui.

Mixing C and C++ Code in the Same Program
I am currently trying to reuse an existing C-library from C++, since i am quite a newbie on this things i found the following article from the Sun Developer Network Mixing C and C++ Code in the Same Program quite interesting.

picotux - the smallest Linux Computer in the World
Today i came across a really fancy project / product, picotux - the smallest Linux Computer in the World.
This thing is apperantly build on top off uClinux and busybox. It connects it self to the outside world over RJ45 or a serial connector and can even serve as a simple web or telnet server.
See the technical page for further information.
