Backup / Replacement Gateway – 1RU PIII 733

Posted on by

dsc07455.JPGSlowing starting to get tired of a flaky extremely cheap duron piece of crap as the proxy server, firewall and gateway…with that said I am still using the machine 🙂

Nontheless, and for the sake of a play with a 1RU server, I picked one of these older whitebox style machines off ebay for 40 odd dollars. The bloody thing sound very sick when I first fired it up so there was nothing to do but pull it apart for a look 🙂

These 1RU machines use very fast 40mm fans which kinda suck from the silent point of view and this machien used very cheap thin 40mm fans. Out with those and in with some old semi decent 40mm x 20mm guys running at a reduced voltage and things started to sound a bit better, the loudest item is the PSU now.

Density Altitude…

Posted on by

When it comes to good old-fashioned hangar flying sessions, one subject that almost never seems to be discussed is density altitude. The reason being, too many pilots do not know enough about the subject. Yet, because of the inescapable influence density altitude has on aircraft and engine performance, it is important that every pilot understand its effects. Hot, high, and humid weather conditions can change a routine takeoff or landing into an accident in less time than it takes to tell about it. There are three important factors that affect air density; ALTITUDE, TEMPERATURE, and HUMIDITY.
