Tortoise or Hare? Nvidia Jetson TK1

September 22, 2020 By Stephen 1 Comment

I’m quite pleased with the Intel NUC boards that came with my surplus Rabbit cloud, but I can’t say the same about the Nvidia Jetson TK1 boards. They’re weird, flaky, limited, and haven’t proved useful even in simple applications. Frankly, I’m not sure what I’m going to do with the 15 Jetsons sitting in my office!

Running Rabbits: More About My Cloud NUCs

September 21, 2020 By Stephen Leave a Comment

As I suspected, the Intel NUCs included in my “Rabbit” cloud hardware are proving much more useful than the Nvidia Jetson TK1s. I received both “Silvermont” NUC5 and “Goldmont” NUC6 machines in my surplus eBay cloud hardware, and both are good little machines, with some notable limitations.

Recalling An HP MediaSmart Server To Active Duty

July 21, 2017 By Stephen 17 Comments

I was recently given an old HP MediaSmart EX470 server along with some other junk hardware. Although it has no graphics, a slow single-core AMD Sempron CPU, and just 512 MB of RAM, I was able to revive it quite satisfactorily. Here’s how I upgraded the hardware and software.

Upgrade to VMware Fusion 3 For Just $9.99!

Are you a Parallels Desktop 5 user eager to jump to VMware Fusion? Or were you too cheap to move from Fusion version 1 or 2? Well now’s your big chance to upgrade from either product to a full VMware Fusion 3 license for under ten bucks!

A High-Performance, Low-Memory Apache/PHP Virtual Private Server

July 30, 2010 By Stephen 4 Comments

I’ve previously written about my Multi-Server Web Hosting Environment and the how I Tuned Lighttpd For Linux to run as well as possible. But I’ve been having weird issues with that setup lately and was forced to rebuild the server entirely. While I was at it, I decided to give Apache another try, since the lighttpd hackery I needed to perform to get things like WP-SuperCache running were starting to get me down. The configuration documented here uses Ubuntu Lucid (10.04), Apache 2.2, FCGI, and PHP-CGI tuned for a 512 MB virtual private server (VPS) running on Rackspace Slicehost.

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!

Co-Processors, GPGPU, and Heterogeneous Computing

June 26, 2017

I’ve been thinking a lot lately about microprocessors, from the many-core CPUs that AMD and Intel introduced recently to the massively scalable GPGPU processing that’s taking machine learning by storm. After years of consolidation on commodity x86 CPUs, it seems that the computing paradigm is turning again to specialized offload processors. This trend towards heterogeneous computing will change the face of hardware, from mobile devices to the datacenter.

Begun, the Patent Wars Have

July 9, 2012

Every day, it seems there is a new lawsuit in the mobile phone industry. HTC, Motorola, Google, Microsoft, and especially Apple and Samsung are actively litigating their way through a thicket of patents. The same is increasingly happening in the rest of the IT industry. But is all this bloodshed really about innovation? Or is it, as one federal judge noted, simply a new form of intense business competition?

Review: Blue Snowball USB Microphone

March 31, 2010

I’ve really jumped into recording podcasts, and am also an avid audio and video conference user. Wanting better sound, I upgraded my Logitech microphone to the highly-regarded Blue Microphones Snowball desktop USB microphone. Here are my initial thoughts.

Deduplication Coming to Primary Storage

September 16, 2008

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time – reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

Virtual Machine Mobility: Of What, and to Where and in What State?

January 16, 2012

Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.

The Terrifying True Story Of Virtual Machine Mobility

December 22, 2011

Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.

Virtualized and Distributed Storage: This Time For Sure!

September 2, 2014

We were never able to achieve storage virtualization in mainstream enterprise IT because we lacked the ability to identify and move data non-disruptively. This has been solved by caching and distributed storage solutions, and it’s only a matter of time before the legacy need for centralized storage falls away.

What’s the Deal with Containers?

October 21, 2016

Lately, it seems like everyone just can’t stop talking about containers. But I’m sensing a distinct lack of real understanding of the technology from many people, not to mention lots of confusion about what containers really mean for today’s datacenter folks. So I set about learning more and figuring out for myself what the deal is with containers. Here’s where I’m at.
