Mac OS X + SSD tweaks
Came across a pretty cool howto to tweak your SSD on a Mac. Only thing I noticed is setting the hibernate mode to 0 made my mac randomly wake up a few seconds after it went to sleep (and happened most often when closing the lid, less often when clicking the sleep button; randomly closing…

nginx reverse proxy with caching
Playing around and searching the web I enabled some decent caching now. Here are some stats: image+html and php. Note that the php on apache (recompiled each request, about 1.5-2sec between every request) versus the cached output has a huge difference. Difference between images and static text files aren’t that huge. Also note that nginx…

nginx reverse proxy

nginx + fastcgi PHP
I recently migrated vm1 to nginx instead of lighttpd. Just for the sake of playing and testing around. As there’s a PHP page as well, I had to set up fastcgi with PHP. I mainly followed this tutorial to try to get PHP working. However, every PHP page I visited returned following error: No input…

OpenVPN packet drops
I recently started to notice following error messages on my openVPN server. ovpn-server[6306]: vpn.rootspirit.com/85.234.x.y:62068 MULTI: packet dropped due to output saturation (multi_process_incoming_tun) This basically means that the TUN or TAP interface is making more packets than the real (TCP) interface can handle. As I need to run OpenVPN using the TCP protocol (instead of the…

OpenVPN & Windows 7
There’s a great GUI out for OpenVPN & Windows, located here. However, this GUI includes an old OpenVPN, that is no longer compatible with Windows 7 and Windows Vista. The TUN/TAP driver will be blocked due to compatibility issues, and when trying to connect to a VPN, you’ll get an error along the lines of:…

If you’re running uptimed (or uprecords) and what to display it in a simple php page, you’ll notice the bold text makes the page somewhat ugly. Use this file to remove the bold chars and make it readable. Examples: zero, one, four, vm1, Sauron
