MiFi 2200

Building a Combination 3G/4G/Wired Wi-Fi Network

June 28, 2011 By Stephen 6 Comments

The Tech Field Day events I run are hotspots of social media, but it has been hard building an Internet presence to keep up. Constantly on the move, I need a flexible network with scalability and failover (and fail-back) between 3G/4G and wired Internet. My latest design relies on CradlePoint’s MBR1200 “Failover Router”, which can load-balance across multiple 3G and 4G data cards.

Why Won’t My MiFi Charge?

February 15, 2011 By Stephen 9 Comments

The MiFi 2200 requires a special charging cable. The bundled charger works, but normal folks (like me) might assume that any Micro-USB cable will work. They would be wrong.

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.

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.

It’s Time To Move Beyond Passwords (Especially On Web Sites)

January 8, 2016

Sure, single sign-on puts all your eggs in one basket. But this is vastly preferable to trusting that hundreds of third-party baskets are secure, especially when they prove on a weekly basis that they aren’t! It’s time to put distributed passwords behind us and switch to systems like SAML, both for businesses and consumers.

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.

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.

Donate Your Swag to School Kids In Need

July 28, 2010

Trade shows are a veritable swag-fest, some with great loot and some with junk. I’ve been critical of the booth babe and chotchkie phenomenon, but my friend Kevin Houston has a better suggestion: Donate your (useful) swag like backpacks and pens to school kids in need.

Why Big Disk Drives Require Data Integrity Checking

December 19, 2014

Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE).

My Core i7 Macintosh SE

May 25, 2017

I recently built the biggest, clunkiest iPad mini case ever, transforming my old Macintosh SE case into an iPad stand. But what to do with that empty case? Why, it’s the perfect size for a custom Mini-ITX PC! Introducing my liquid-cooled Core i7 monster Mac SE!

The Rack Endgame: A New Storage Architecture For the Data Center

September 3, 2014

Top-of-rack flash and bottom-of-rack disk makes a ton of sense in a world of virtualized, distributed storage. It fits with enterprise paradigms yet delivers real architectural change that could “move the needle” in a way that no centralized shared storage system ever will. SAN and NAS aren’t going away immediately, but this new storage architecture will be an attractive next-generation direction!
