Teaching Science with Wi-Fi (Thanks, Ruckus and MetaGeek!)

February 10, 2012 by Stephen 3 Comments

As a parent, especially a techie one, you never know when a teachable moment is going to appear. Last night, I mentioned that I was testing a new Ruckus access point and enthused about how fast it was. My 12-year-old asked, â€œwhy is it so fast?â€ This led to a wonderful discussion about radio waves, congestion and propagation, and spectrum licensing. Yeah, I’m that kind of dad.

Hands-On Review: Clear WiMAX Service (and PXU1900 USB Modem)

August 25, 2011 by Stephen Leave a Comment

I know lots of folks who are happy with Clear or Sprint WiMAX service, and I applaud them for their no-contract Day Pass option. In fact, I wouldn’t hesitate to suggest that others go the same route I did: Buy a Clear modem on eBay and pay $10 per day whenever you need connectivity. But I strongly discourage readers from signing up for a long-term contract with Clear. Sprint subscribers will likely be upgraded to LTE eventually, but the future of Clear is very, very cloudy.

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.

The 2018 iPad Pro is a Beast!

The third-generation iPad Pro is a great machine but also a bellwether of change at Apple. It will be very hard for the rest of the mobile and client computing industry to keep up with this kind of progress!

The iPhone Revolution 10 Years Later

January 9, 2017

10 years ago today, Steve Jobs introduced the iPhone, perhaps the most revolutionary technological product in history. There have been many important products introduced before and since, but nothing else was as groundbreaking as the iPhone. Watching the introduction, it’s amazing to see just how many things were introduced that day that have become integral to daily life today.

The Rack Endgame: Open Compute Project

September 17, 2014

On reading my thoughts about the evolution of enterprise storage, many pointed out that this looks an awful lot like the Facebook-led Open Compute Project (OCP). This is entirely intentional. But OCP is simply one expression of this new architecture, and perhaps not the best one for the enterprise.

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.

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.

The I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

Are You a Hypervisor Hugger or a Storage Stalwart?

November 14, 2011

The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide.

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!

Replacing Google Reader With Feedbin and Reeder

May 5, 2013

I am an avid Google Reader user, so I’m thoroughly annoyed by Google’s decision to kill it as of July 1. But there’s no stopping the tide, so I’ve made the move to Feedbin as a Reader replacement as of today. It’s a slick, snappy web application with a committed developer and, critically, support for Reeder, my favorite offline RSS reading application. Let’s hope this works!
