A High-Tech Water Heater? Yep! Introducing the A. O. Smith Vertex

November 15, 2012 By Stephen 5 Comments

I justify spending six times more on the Vertex 100 for a simple reason: It’ll keep up with the heavy water use in my house. I’m hoping I’ll never have to worry about hot water as long as I live here. The fact that it saves over $100 per year due to energy-efficient design is just icing on the cake.

How I Eliminated Over 2 kW of Lighting at Home

January 3, 2012 By Stephen 7 Comments

The average home is incredibly inefficient, and nowhere is this more obvious than the ubiquitous electric lightbulb. Compact fluorescent (CFL) and LED lights are an order of magnitude more efficient at converting electricity to lumens rather than heat, but making the switch is not simple. The limitations, pricing, and sheer variety of lighting options are daunting.

My 2012 Project: Improving Energy Efficiency

January 3, 2012 By Stephen 3 Comments

I am in the process of upgrading my own home to make it more energy efficient. I do this mainly as an exercise of faith and science, since my electric and gas bills are not currently all that expensive. But I just can’t countenance burning 10 times more electricity than I need to, even if I can afford it. It’s also an exercise in geekiness, since today’s lighting alternatives and appliances have an undeniable techno-cool factor about them.

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.

New England Takes On Seattle To Determine Who’s Number 2 … In Tech!

January 19, 2015

Although New England ought to win that big football game, they’re losing when it comes to innovation and technology. Seattle and Austin are gaining rapidly, and Massachusetts has itself to blame thanks to oppressive non-compete clauses and the threat of litigation. As for Tech Field Day, look for us to return to Silicon Valley for seven of our nine full events in 2015. At least now you know why!

Sony NEX-7 Hands-On Review Part 1: The New Super-Camera

March 26, 2012

It took over five months, but Sony finally delivered my NEX-7 kit on March 8 (my birthday, natch!). After using the camera for a few weeks, I can say it’s exactly what I hoped it would be: A worthy upgrade over the NEX-5, and perhaps the best enthusiast camera on the market. But it’s not without flaws, including some surprising shortcomings. Here’s my hands-on review!

MacBook Users: Encrypt Your Drive with OS X FileVault! It’s Easy and Free!

December 20, 2012

Once you encrypt your MacBook’s drive with FileVault 2, you’ll never even know it’s there. But if you ever lose your machine, you can rest easy knowing that your data is safe. Considering how well this solution performs and that it is included free of charge, there is no reason not to use it!

From LAN Manager and SMB to CIFS: The Evolution of Prehistoric PC Network Protocols

March 22, 2012

Computers aren’t much good on their own. This simple fact was evident even at the dawn of the microcomputing age, and has never been more true today in the “post-PC” world. If the standard microcomputer is the “Wintel” box (Microsoft’s Windows, Intel’s CPUs, and all that implies) then the standard network services protocol is SMB. So let’s take a nice deep dive into SMB, past, present, and future!

Why Are PCIe SSDs So Fast?

June 12, 2013

The world of storage can be confusing, with obscure terms hiding massive differences in technology and performance. Such is the case for the latest PCI express SSDs: They are much faster than traditional SAS or SATA SSDs, but many aren’t sure exactly why. In this article, I will try to explain the real difference.

Why I Am Biased Against FCoE

October 21, 2011

I am biased against FCoE because it’s too new to be blithely and broadly recommended for production enterprise use. That’s all. Yes, the standards are standardized and there are products extant. But that’s not enough for me.

On the Death of Innovation, or “These Kids These Days!”

May 21, 2012

An obnoxious meme has returned to the fore lately, claiming that innovation is dead. The hippies did it, or maybe it was the Internet, or even a decline of America. But nothing could be further from the truth, and statements like this make me question the perspective of the speaker.

VMware’s Hardware Partner Strategy: Heads I Win, Tales You Lose

February 11, 2013

VMware is in an enviable but tricky situation: The company must work closely with hardware partners, keeping these prime sales and promotional channels happy and supportive. But VMware must also innovate around proprietary OEMs, subverting their products with integrated software before a rival steps up with an integrated alternative.
