Is there no such thing as a cheap, prepaid data SIM in the USA?

October 2, 2012 By Stephen 13 Comments

It’s hard to believe that a true prepaid mobile data SIM doesn’t exist in the USA, but it’s true. A GoPhone, H2O, or Net10 SIM isn’t a bad idea for your smartphone, but it’s not exactly cheap. The best option for those needing just mobile data is a local Virgin Mobile hotspot or a brand new Android phone or iPad!

Verizon Offers Double 4G Data (But Not For MiFi)

November 12, 2011 By Stephen Leave a Comment

Verizon Wireless has a promotion running in November that doubles the data allowance for 4G phones. This is a great deal compared to competitors, and it comes with Verizon’s excellent 4G LTE coverage and performance. But it only applies to smartphones, not MiFi “mobile broadband” devices, and the offer ends in December.

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.

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 […]

Regarding My Symbolic Links and Good Reads

April 16, 2015

I’ve been told that my shares drive traffic to the blogs I read. I’m thrilled that I can share great writing with you in this way, and I hope you find it valuable! But just in case you don’t, I hope you’ll take advantage of the fact that I filter these posts for you into “Symbolic Links” and “Good Reads” so you’ll find it easier to ignore them.

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.

Follow the Yellow Brick Road to the Software-Defined Future

November 29, 2012

The Software-Defined Datacenter is a great concept, but it just won’t work. The big enterprise companies will never allow VMware (and daddy EMC) to commoditize them out of existence, so useful implementations will be rarer than ruby slippers. The best we can hope for is point enhancements to enable greater virtual machine mobility through SDN and improved storage integration.

How to Get Me to Write about Your Company or Product

March 15, 2012

Blog posts are really, really important for PR and awareness these days. And posts on independent sites like this one are critical to get awareness and search engine ranking. I get dozens of requests every week from companies wanting me to write about them. So I thought it would be a good idea to lay out exactly what it takes!

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!

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.

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.
