Fitness Trackers… I win

The fitness tracker craze….

I win….

I tossed a “fitbit” tracker in to a paint mixer.

Laptop Buyers Guide

(Current as of Q2/2015)

I get asked all the time, “what laptop do you recommend?”

It’s a question  with a complex answer, based on your budget, how you use it, and hardware features available on the market at any given time.

Because model numbers change so quickly, I wont cite specific models, so this article is more of a buying guide – how to figure out which features you need, and select a manufacturer.  Once you know what you’re looking for, you can shop online or at your local big box retailer.

In the digital and online world, it’s easy to miss some forms of access, and remember off-hand every single system where the employee’s access should be revoked.

The level of risk increases when the employee separation occurs involuntarily, which might create a situation where the former employee is disgruntled, and increases exponentially if the employee has administrative privileges to sensitive systems.

In this article, I will attempt to outline best practices for a policies and processes around identity and  access management, enumerate specific forms of access, many of which might be overlooked, and share some anecdotes resulting from the failure to properly revoke a terminated employee’s privileges.

Science generally agrees that “mankind”, homo sapiens, is about 200,000 years old.

During that span of time, technology has advanced at an ever-increasing rate, but there have been only a small handful of innovations – fundamental changes – that altered mankind’s ability to express itself technologically.
