Mavericks 에서 PHP 활성화

아래처럼 하면 끝~

Mavericks comes with PHP 5.4.17, so now we need to turn it on:

sudo nano /etc/apache2/httpd.conf

Use ctrl+w to search within nano and search for “php”. Uncomment the first line you find (remove the #):

LoadModule php5_module libexec/apache2/libphp5.so

Press ctrl+o and then ctrl+x to save and exit. Restart Apache for the change to kick in:

sudo apachectl restart

Had the same problem with my MacBook Pro 13" (Late 2011), switching adapters didn't work, SMC reset didn't work and I was just about to quit trying and take it to the shop when out of frustration I've unplugged the battery connector and plugged it right back in and that FIXED IT!!

(note: do not remove the battery since that will void the warranty, just remove the connector)

Pure IMU-based Positional Tracking is a No-go

rotation VS orientation

An orientation is a state: “the object’s orientation is…”
A rotation is an operation: “Apply this rotation to the object”

That is, when you apply a rotation, you change the orientation. Both can be represented with the same tools, which leads to the confusion.
