Check Your Mac’s Drive and Reclaim 5 GB of Wasted Space!

July 24, 2015 by Stephen 8 Comments

Since most MacBooks are SSD-only, one would think Apple would be careful about leaving junk around on the drive. But many people are finding 5 GB wasted for a years-old leftover Mac OS X install image! Here’s how to reclaim that space if you’re missing it…

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

How Will Cisco Recover From The Consumer Strategy Blunder?

January 2, 2013

Cisco made a massive strategic blunder in the last decade, aggressively moving into consumer devices rather than focusing on their core enterprise and service provider markets. It seems that Cisco is now in the process of rectifying this mistake, but charting a path to growth is an entirely different matter!

EMC Redefine Possible (TL;DR Edition)

July 9, 2014

EMC made quite a few announcements today at their “Redefine Possible” event in London. There’s a lot of coverage out there already, so I decided to present a summary of the whole thing in “too long; didn’t read” (TL;DR) fashion.

Free as in Coffee – Thoughts on the State of OpenStack

May 2, 2016

Last week I headed to Austin, Texas to attend the semi-annual OpenStack Summit there. Along with the usual socializing, I was looking to understand the current state of the technology: What does OpenStack really mean these days, and where is it going? Let’s start with “free”. As “the Internet” is quick to point out, this critical word has multiple […]

ZFS Is the Best Filesystem (For Now…)

July 10, 2017

ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. Here’s why.

Not All 802.11n Networks Are Alike

July 2, 2011

Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation. And some client devices may never reach the levels of performance expected by consumers due to hardware limitations.

The Best Mac OS X Terminal Font: Glass TTY VT220

October 6, 2015

More than five years ago, I blogged about a “stupidly cool” terminal font. Now that Mac OS X isn’t a big cat anymore, I figured it was time to repeat that: If you’re an old-school computer nerd like me, Glass TTY VT220 is the coolest terminal font for Mac OS X!

Review: American Standard’s Champion 4 Toilet Flushes Almost Anything

July 31, 2012

Although most crappers are crap, plumbing companies like American Standard are hard at work innovating to eliminate the excrement. The current champion is fittingly called the Champion 4, and I have purchased, installed, and tested two examples of the type. The Champion is engineered to reduce the most common causes of clogs, and it has proved effective and “hands-off” in my real-world testing.

The End of Unlimited Data – Part 1: The Buffet

June 2, 2010

The headlines are all over the blogs: AT&T announced today that they are doing away with “unlimited” data plans and replacing them with limited packages at lower prices. I’m not going to repeat the news – Boy Genius Report has the best overview I’ve seen. Instead, I’m going to explain why I think this is a positive move for everyone involved, including AT&T, the customer, and the US wireless phone industry as a whole. This first post talks about the buffet mentality that got us here.
