Hello Hexo and Goodbay Octopress
Speed is the main concern. Octopress can be very slow , while hexo is lightening fast.
Second reason is that i like this pretty theme Yilia. Many thanks to its author litten.
Some math formulas in my old octopress posts could not be rendered properly. So i changed contents of the file
/themes/yilia/layout/_partial/mathjax.ejs to following:
* must be manually escaped to get mathjax working properly.
Those amazing posts i wrote in octopress which used d3/impress/p5 could not work anymore. Currently i do not have much time to make them work in hexo(you known, final exams are coming!), but i will do this in future.
