Back From the Pile: Interesting Links, February 11, 2011

February 11, 2011 By Stephen 1 Comment

I’ve spent this week in San Jose, CA at Tech Field Day 5, and that’s the bulk of my news. We heard from great companies: Symantec, Drobo, Druva, Xangati, NetEx, InfoBlox, and HP. Whew!

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.

What’s the Difference Between a Jailbroken and an Unlocked Phone?

May 5, 2012

If you’ve traveled much, you’ve probably run across â€œunlockedâ€ mobile phones and devices. If you own an Android or iPhone smart phone, you probably also heard about â€œjailbreakingâ€. It seems like lots of people are confused about these two things, so I decided to write down a quick post explaining them.

Debit or Credit? Always Choose Credit!

December 19, 2013

“Credit of debit?”ï»¿ It’s all very confusing for American shoppers. But the news about a massive point-of-sale data theft at Target makes one thing very, very clear: Always choose “credit” when the cashier asks!

A Watch Guy’s Review of the Apple Watch

April 27, 2015

Is the Apple Watch a personal communication revolution like the iPhone, a well-executed gadget like the Apple TV, or a total miss? Does it mark the end of the the world as we know it for watches? And what’s it like to use one? I’m a watch guy and a gadget guy, so perhaps my perspective will be of some value.

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.

Infographic: Real-World Port Throughput Relative To Thunderbolt (Formerly Light Peak)

February 21, 2011

Just how fast is 10 gigabits per second anyway? To help out, I’ve prepared another napkin-tastic infographic!

Introducing Rabbit: I Bought a Cloud!

September 10, 2020

We live in a world of cattle, not pets, and Kubernetes rules the roost. I’ve been meaning to spend some time getting up to speed on the latest but didn’t have enough hardware to make that happen until now. I recently bought a whole pile of surplus hardware so I will be able to experiment with orchestration and container platforms in the office.

Datacenter History: Through the Ages in Lego

October 22, 2013

Readers of my blog know that I love computer history. Therefore, I decided to focus my entry in Juniper Networks’ “Build the Best (Lego) Data Center” contest on the history of computing. Specifically, I would re-create key historic machines to contrast them with a modern view.

A Fairy Tale of Two Storage Protocols

September 23, 2014

It’s clear how this fairy tale ends. So many companies are using “S3 plus” as their standard interface, and even inside their solutions, that it’s safe to say it’s won the cloud storage API battle. But S3 isn’t a finalized spec – the industry will extend and improve it over the coming years. Soon we’ll have a cloud storage standard based on S3, just like we have a LAN file services standard based on CIFS.
