Soft shoulder signs keep mocking me

Soft shoulder signs keep mocking me

April 17th, 2009

I’ve been thinking a bit about my shoulder situation. Even though I’d say I’m 85% healed up, that last 15% is proving to be significant because I can’t do things like lift heavy lead batteries or push up on heavy hatch covers anymore. The arm and shoulder feel fine during daily life use, but once […]

Microcomputer conference @ Asilomar State Park

April 16th, 2009

I’m at a microcomputer conference in Asilomar Park, and while the conference is amazing and fun, the park it is held at is amazing in it’s own right. I was up late chatting last night, and got up early this morning, before the sun came up, to go sit out by the ocean and think, […]

Accessing Windows admin utils from the command line

April 13th, 2009

With the advent of PowerShell and headless operation, the Microsoft Windows operating system is slowly earning the much sought after status of ESOS or “enterprise server operating system”. But what about all those spiffy GUI admin tools many of us have grown fond of? If, for whatever reason, you need to launch one via the […]

El saga del tooth

El saga del tooth

April 11th, 2009

For whatever reason I love mixing together badly constructed Spanglish phrases. It just sounds funny to me, and if you’ve ever seen any Spanish language dramas, you’ll know adding just a few Spanish connecting words triples the drama. “The saga of the tooth” is boring, but change a few words to “El saga del tooth” […]

My friend Greg Bennick

My friend Greg Bennick

March 24th, 2009

I met Greg Bennick many years ago at an AmeriCorps event. Ever since then I’ve been fascinated by this guy. He’s involved with some of the most profound things I’ve ever had the privilege of experiencing. From TRIAL to Flight From Death to Words as Weapons, he’s always involving himself in important issues in big […]

Review of DataSafe security wallet

Review of DataSafe security wallet

March 22nd, 2009

In a fit of frustration the other day, I broke my wallet by slamming it down on my desk. The frayed edges of my trusty old wallet couldn’t take the strain, and my credit cards, loyalty cards, and RFID cards ripped through the frail seams and went flying all over the place. The deflated little […]
