I was reading reddit the other day and stumbled upon the fact that wikipedia has an API. Neat I thought, and having some free time since my exams are now over I figured I would play around a bit with it. When I browse wikipedia I often click from link to link, and have come to the conclusion that all articles are 6 degrees of separation. For example I can go from Ubuntu to Tesco to Japan to G8 to United States to George W. Bush bet you never knew Ubuntu was connected to George W. Bush. I once wrote a map of the internet program that people seemed to like to download and modify so in that spirit I wrote wikimap.py to map wikipedia. wikimap.py Requires pygraphviz (Install using sudo aptitude install python-pygraphviz). To use the program simply run the program and give it the wiki page name for example “python wikimap.py Norman_Graham” Note that Ubuntu is Ubuntu_(Linux_distribution) and you can find the full name in the address bar of your browser. For more complicated maps use wikimap.py –help for full usage info.

Here are a few examples that I created with wikimap.py


And a really large one being viewed in inkscape.

More examples including the dot files can be found at http://www.files.earobinson.org/wiki/. But there are a few features I would like to add:

1. Generating the graph using python-pygraphviz currently takes a really long time and I would like to be able to do it faster
2. Page links currently include templates, I would like to only use links in the body of the text
3. It would be nice if the software cached previously seen connections. (But then I need to detect updates to that page)

If anyone has a nice simple soultion to any of those problems leave a comment. Also if you are able to generate any neat images I would love to see them.

So now that I have my XO OLPC computer I wanted to find something to do with it. As I said before its the web cam that really impressed me and so I decided to start playing with that. After jumping onto the #OLPC freenode irc room and asking them a few questions I was quickly able to write this python program.

• imagecapture.py
• imagefilter.py

Set it up as a cron job and upload pictures from outside my apartment window every hour. I’m not sure how long ill be keeping it running and if I play with the laptop and dont turn off the script I guess it will upload pictures of me.

Well for anyone interested the important code to take a picture is: [sourcecode language="python"]os.system(’gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc ! filesink location=’ + filename)[/sourcecode] and I would love to hear what you have been doing with your XO.

The other day I stumbled upon Chris Harrison’s internet map, the only problem I found with his map is that I wanted to know exactly which country each network connection was in. So using the DIMES public data repository, and 1site1moment’s country boarders I have mapped the internet for myself.

From Public

Feel free to download the source code and come up with your own internet map, I would love to see what other people can come up with.

UPDATE 01: Image is back up, If the source code link wont work for you email me and I will send you a copy. Feel free to host this anywhere you like just post a link back to this site.

UPDATE 02: Source code can now also be found here.

UPDATE 03: Would love to see what other people can do with this.
