The two week has passed since I opened moved this blog to here. Finally, I got a domain name “diveintodata.org” three days ago, and then I set my blog to be published as new domain. Now, I’m happy :)
Anyway, from now I’m going to write at least one articles within a week. The articles will discuss computer science issues, especially newly emerging database issues.
Sometimes, I confront the situation to write mathematical symbols or formula in online. Actually, by using latex or a kind of word process we can write them, whereas it is difficult to do so in online. However, I found some convenient ways for them. This site (http://sixthform.info/steve/wordpress/?p=59) introduces many ways to write easily mathematical symbols or formulas in online. Among them, I prefer to the following methods because they provide immediately math-symbols image urls generated by online input.
