Ever need to track the performance of your internet connection in a pinch? I did the other day when a customer we installed DIA services for complained of poor performance. I’ve tried many schemes in the past to do this kind of testing and this time I wanted to do something new. I also wanted

Ever wonder how people get those cool blow off turbo noises or crackle of their exhaust? How about clear audio from inside the cabin? Today I’m going to teach you how to build your own sound studio in a bag. We’re going to mic up my exhaust, intake/turbo and myself while I drive around. After

I’ve struggled to improve Samba (SMB) performance between my Mac Pro (Late 2013) running OS X Yosemite 10.10.2 and my CentOS 6.6 Linux server. The server has a large ZFS share with all my backups and archives as well as various KVM instances running off SSDs. My Mac Pro absolutely must access that ZFS share
Working on updating some ServerTech CDU firmware today I found that they wouldn’t connect to my fresh new FTP server. I checked my firewall, I checked my server log, and saw that they weren’t authenticating correctly:
