I am a fun of vim and work a lot with IPython Notebook recently. It would be cool to combine the two.

There is something missed in previous notes about configuration of Apache and PHP. Frequently, MySQL goes with them together, but it’s disabled in php.ini by default. Since MySQL 5 is now spreadly used instead of the forth edition, so it’d better remove ‘;’ before the line showed below in php.ini. ;extension=php_mysqli.dll mysqli maybe means MySQL […]
