Web Tools

I spent a lot of time on reading articles on the web. Several web tools are frequently used for organizing my reading/writing:

• Twitter: Anything interesting is posted into Twitter
• Diigo: I started using Diigo and stopped using delicious, because I found Diigo is more powerful. 
• WordPress: My own blog containing my thoughts and comments on technical stuff.

METAPOST

One of my favorite tools for drawing graph is METAPOST, which is developed by John Hobby and based on Donald Knuth’s METAFONT.  The graphs generated by METAPOST is much better than the ones generated by Visio.   Moreover, it is easier to describe a graph with mathematical properties in a METAPOST program.  For example, it only took me around 15 minutes to reproduce Langford pairings in Knuth’s book. If Visio were used, it would take much longer time to make everything right.

The reproduction of Langford pairings is here.
