"Forget" your access point(s) on your existing UniFi Controller before adopting it on your hosted controller 3
If you’ve ever set up a Ubiquiti UniFi access point, such as the UBNT UAP, UBNT UAP-PRO, or UBNT UAP-AC-PRO, you’ve had to run UniFi Controller software required to adopt, configure, and manage your UniFi devices. When I set up a UAP-PRO in our house (see my install guide) I ran the UniFi Controller software full-time on […]

The Ubiquiti EdgeRouter Lite can replace the Google Fiber Network Box 26
I’ve been a Google Fiber user (and fan) since the service first hit Provo, Utah. I have a vacation home there, so while I don’t get to benefit from the Gigabit speeds on a daily basis, I certainly take advantage of it while I’m there. Because it’s a vacation home, I rely […]

Ubiquiti UAP-PRO access point 20
Getting decent WiFi coverage at my house has always been a challenge. The house is three stories (the bottom floor is a daylight basement) and has a footprint of 50′ x 100′. A four car garage extends the footprint even farther to the south, and because I use WiFi-controller irrigation […]

Our family has a cat and two indoor dogs (Japanese Chins). And on most days, we love them. OK, so we love them every day. But when you’re training a new puppy to “wait to go outside,” or dealing with a cat that believes she owns the house and can cough up […]

A burned out bulb on your car isn’t just an annoyance, it’s a safety issue… and one that could get you pulled over. So many of my favorite COPS episodes on TV start with a plain old “your tail light is burned out” traffic stop. Bad boys, bad boys… what’cha […]

Summer 2015 in Seattle has been officially declared the hottest summer here on record (check my weather station’s 2015 max temps on my Weather Underground weather history graph for geeky details). For those in the Pacific Northwest living without central A/C, it’s been miserable. And for those fortunate enough to have central air conditioning, […]

The Ferrari Testarossa, along with its later 512 TR and F512M variants, are iconic cars of the 80s and 90s. Every kid my age wanted to be Sonny Crocket cruising around Miami in a white Testarossa. What we never saw, however, was Crocket having trouble starting his Testarossa. Every time he had […]

The Problem In the “early” days of the internet, you could find free Dynamic DNS (DDNS) accounts everywhere. The providers of those free services, such as DynDns, hoped that by giving you a freebie, you’d eventually become a paying customer for one of their pay services. Unsurprisingly, that’s not what happened. […]

Rasmus Lerdorf's opcache-status script 2
When I upgraded to PHP 5.5, I also said goodbye to my beloved APC cache (which never let me down) in favor of Zend OPcache, because it’s already part of the PHP package. Back when I used APC, one of my favorite tools was the apc.php script that showed cache status and allowed me […]
