Enabling a USB to Serial Port Adapter under OS X 10.9 Mavericks

Appears that with the coming of OS X 10.9 Mavericks, we are once again faced with various peripherals that cease to function correctly. I often do work that requires a serial port.  I’ve carried a Keyspan USA-19HS with me in my briefcase for close to a decade (maybe more).  I’ve always been able to get it to work properly, but recently, with my upgrade to a 15″ MacBook Pro Retina Display and subsequent upgrade to OS X 10.9 Mavericks, my trusty little friend may have met his day.  Keyspan does not show a driver that supports OS X 10.9 and loading the 10.8 driver resulted in no change from not having the driver. I...

Using Hazel, Python, Lingon, and ARP to Determine if a Device is on your Network

A friend of mine (he has a blog over here) gave me an idea for a program. He wanted to know when his kids got home (and when they left).  His idea was to have an application that would interrogate his wireless network to see if a specific client was associated with his Access Point.  I started down the path of using SNMP to query the Apple AirPort Extreme he owns, but quickly gave that up.  The main reason I gave up on that solution (which would have been perfect) is that Apple, in their infinite post-Jobs wisdom) has removed support for SNMP configurations from AirPort Utility 6.0 and has eliminated SNMP from their newer AirPort models.  So, dead...

How to Recover the Google Nexus 7 to Stock ROM on OS X

See my other article here for instructions on how to root the Nexus 7 under OSX in the first place.  Some of those instructions are repeated in this post. Install Android SDK I know it’s a pain, but really if you’re going to hack around with an Android device you should go ahead and do this.  Additionally, Google has made the process a LOT easier now. Download the SDK from here.  You probably won’t need them, but instructions are here. Unzip it into a folder (doesn’t matter where, though if you want to keep it around, somewhere sane). [Optional] Open Terminal and update your PATH variable by editing .bash_profile and adding the following line: 1...

How to Root the Google Nexus 7 on OS X

I got a Nexus 7 last year and have been playing with it on and off since then.  Recently I upgraded to JellyBean 4.2.2 and it toasted my Root.  I went searching for the Root instructions again and found that things had changed since I had last done it.  I decided to write this article to create a permanent place to document this process, hope it helps you too. Install Android SDK I know it’s a pain, but really if you’re going to hack around with an Android device you should go ahead and do this.  Additionally, Google has made the process a LOT easier now.

What I Learned about Time Machine backups from timedog

I love Time Machine. For years and years backups were something I was supposed to do, but never found the time to do. Backups were difficult, you had to purchase backup software, find a drive, set them up, and then either manually execute your backup (which is what I did for years) or figure out how to automate them. Enter Time Machine With the launch of Mac OS X 10.5 (“Leopard”), Apple included this brand new Backup system. But, this article isn’t about Time Machine. Perhaps I’ll do one of those at some point. This article is about what I just learned about TIme Machine. I’m backing up a lot of stuff I shouldn’t be…...
