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.

Go Get a ProtonMail Account and Protect Your Online Life!

July 19, 2017

It’s an easy decision: Get a free ProtonMail account and use that as your verification address for important financial and social media accounts. Keep using whatever email account you like for regular communication, but don’t mix security and communication!

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.

Microsoft’s Overlooked Innovation

February 15, 2010

It’s fun to bash Microsoft. It’s easy, too, with Apple solidly conquering the high end of the PC and mobile markets and Google’s command of the Internet. But how fair are these articles skewering Microsoft, such as “Microsoft’s chronic lack of innovation” published today at Techworld? I suggest that Microsoft innovates as well as, if not better than, any other massive company. But no one innovates like an outsider.

Edward Snowden Is Right: We Must Protect The Internet

March 19, 2014

Edward Snowden, NSA whistleblower, appeared at TED2014. His video, embedded below, must be watched. You may think he’s a hero or you may think he’s a villain, but he’s unequivocally right about one thing: We must protect the integrity of the Internet and online communications or we risk disrupting the world economy and all of our lives.

Why Buy a NEX-7? Why Sony NEX At All?

October 17, 2011

Your tweets about your NEX have intrigued me a bit…I get tired of lugging my Nikon D90 around with my kids, yet I find the quality of most point-and-shoot cameras terrible…so the NEX seems like an interesting compromise.

Ten Terrible Apple Products

June 14, 2012

I’m often accused of being an Apple fanboy. While it’s true that I love my vast selection of fruity products from Cupertino, I’m not blind when the company makes mistakes. In fact, I think Apple’s mistakes are as enlightening as their successes: They reveal a company that is fallible, sometimes learning but often allowing the junk to rot far longer than other companies would.

Scaling Storage In Conventional Arrays

November 19, 2013

It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just werenâ€™t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.

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!
