Web sharing cannot be started after Lion upgrade
After upgraded to Lion, Web Sharing cannot be started. In my case, it’s caused by the missing fastcgi_module. To fix, open httpd.conf in /etc/apache2/ and comment it out:
LoadModule php5_module libexec/apache2/libphp5.so # LoadModule fastcgi_module libexec/apache2/mod_fastcgi.so

How to build Fuego on iPhone
There are two challenges when building Fuego on iPhone:
- to build the boost library on iPhone
- to include appropriate files from the Fuego source and interface with the engine
I created an iPhone project. To build:
- please follow Semmel’s blog to build the boost library to an iPhone framework
- download the Fuego iPhone project from github
- add the boost.framework built in step 1 to the iPhone project downloaded in step 2
- compile
Fuego 1.0, iOS 4.2.
Enjoy~

How to install mysql gem on OS X Snow Leopard
If there is an error when staring a Rails application via a MySQL connection:
Status: 500 Internal Server Error
uninitialized constant MysqlCompat::MysqlRes
Assume MySQL is already installed, for example, via homebrew:
brew install mysql
or other means.
1. Un-install the existing mysql gem (if any):
sudo gem uninstall mysql
2. Locate the ‘mysql_config’ file:
find /usr -name 'mysql_config'
3. Re-install mysql gem:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/bin/mysql_config
Note: replace ‘/usr/local/bin/’ with the corresponding mysql_config path found in step 2.
cheers~
