USB Ethernet Not Working in macOS 10.12 Sierra?

October 22, 2016 by Stephen 24 Comments

It’s become routine: Each new update of Mac OS X macOS breaks third-party drivers and applications. This time it’s many popular third-party USB 3.0 Gigabit Ethernet adapters that don’t work. But have no fear! It’s a simple fix!

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.

Preserving Your Credibility Is Your Prime Directive

June 4, 2012

I hope this post isn’t too “out in left field” but I thought it needed to be said. Independent social media has evolved into a powerful mechanism to influence belief, behavior, and (yes) buying. I take my little dollop of influence very seriously, and feel an incredible responsibility to live up to the trust placed in me by others. I will try every day not to let you all down!

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.

Rocking Out With the Topping VX1 Desktop/Bookshelf Amplifier

October 6, 2015

A few months back, I asked folks on Twitter and LinkedIn for recommendations for a desktop amplifier for a pair of bookshelf speakers. I ended up with a Topping VX1, one of the many “Class-T” digital amps lauded by audiophiles for their excellent sound reproduction. Boy am I impressed! It’s rare that such an inexpensive gadget (around $100!) delivers so much performance!

Here’s Something Your Raspberry Pi Can’t Do: Gigabit Ethernet and SATA in the Olimex A20-OLinuXIno-LIME2

May 25, 2016

I’ve really enjoyed experimenting with the Raspberry Pi, and have even deployed a few as UNIX servers in my home and office network. The quad-core performance of the latest Pi models is awesome, but serious I/O limitations remain. With just one USB 2.0 interface shared for all network and storage operations, you aren’t going to […]

Mac OS X Lion Adds CoreStorage, a Volume Manager (Finally!)

August 4, 2011

Mac OS X was majorly deficient in that it lacked a volume manager. This wouldn’t seem like a big deal to the average user, but held back the operating system in so many ways. A volume manager brings storage virtualization to an operating system, allowing storage capacity efficiently to be managed and manipulated. But all this has changed in Mac OS X 10.7 â€œLionâ€ with CoreStorage.

It’s Time To Speak Out Against Sexism In IT Recruiting

May 6, 2013

I have waged a long-standing battle against the sexist and offensive use of scantily-clad, non-technical “models” at technical trade shows. Sometimes known as “booth babes”, the use of women in this way harms our entire industry and makes companies look stupid, to boot. But when a recruiting firm uses such offensive tactics, it does even more harm, verging on illegal!

How To Keep Your Family Activities In Sync With A Shared Google Calendar

April 18, 2010

Smartphones, computers, and iPads are proliferating in families today. Although my three kids do not (yet) have their own mobile phones, we still have quite a few devices with calendar functions: An iPhone each for me, my wife, and our au pair along with an iPad and a few computers. Using Google Calendar, we have set up an awesome shared calendar to keep all of our activities in sync. Read on for instructions!

Faster Ethernet Gets Weird

June 19, 2015

“One size fits all” doesn’t work for Ethernet, but this proliferation of speed options sounds like trouble without automatic capability negotiation. It’s nice to have options, but the IEEE must remain focused on interoperability and rein in the interests of the various companies proposing next-generation Ethernet technologies.
