The Thunderbolt extruder is a custom AIO Robotics design. Here it is in its element, printing a "wood" hex for a 3D Catan board!

Thoughts on the Modern Miracle of 3D Printing

Although I enjoy my AIO Robotics Zeus 3D printer, I’m under no illusions that it’s an economical or practical device. It’s a toy that takes me into the future, and I love being there!

Check Your Mac’s Drive and Reclaim 5 GB of Wasted Space!

Since most MacBooks are SSD-only, one would think Apple would be careful about leaving junk around on the drive. But many people are finding 5 GB wasted for a years-old leftover Mac OS X install image! Here’s how to reclaim that space if you’re missing it…

Select the location to write the image, then choose "sparsebundle disk image" before setting the size. You can add encryption here, too, and the tool will ask for a passphrase when you click "Create".

How to Use Mac OS X Sparse Bundle Disk Images

I’m a big fan of “sparse bundle” disk images in Mac OS X. They allow me to create encrypted repositories for valuable data that can efficiently be rsync-ed between disks and don’t waste a lot of space. So I thought I’d write up a bit on what they are and how they can be used.

I have a "link blog" of interesting tech articles (and another for personal stuff!)

Regarding My Symbolic Links and Good Reads

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.

The third-generation drobo is just about the perfect home storage device

Generation 3 drobo: Fall In Love All Over Again

I remain a huge fan of drobo generally, and the third-generation drobo remains the best choice for home storage. It’s the perfect storage device for the long haul, and the performance improvements make it a no-brainer. Get one.

The Sony NEX-5 packs the optics and sensor of a digital SLR into a compact body

Sony NEX-5 Camera Review

The world of photography is like so many others: A vast gulf separates the amateurs and enthusiasts, from equipment to nomenclature to skills. I am decidedly in the amateur camp when it comes to photography, but I recently upgraded to a new compact interchangeable-lense camera, the Sony alpha NEX-5. It is an excellent match for my needs, allowing me to expand my skills and explore more advanced photographic techniques without sacrificing portability and ease of use.

Cisco's UCS C3160 is a "storage server" for the all-Cisco rack

Cisco’s Trojan Horse

Industry watchers like me have long wondered when Cisco will transform itself into a full-line IT infrastructure vendor. This strategy was tipped in 2009 as Cisco barged into the server market with UCS. But one leg of the stool is still missing: Storage remains the province of Cisco partners like EMC and NetApp.

We Live in the Future: Robotic Cat Litter Boxes!

This post is a bit of a break from my usual gadget-fest, but the object in question isn’t that far off: It requires electricity, costs more than average humans can justify, and simplifies a task we’ve all been doing fine up until now. That’s right: An overly-expensive electric cat litter box. Predictably, I love it.

VMware mucked with vSphere licensing again...

Storage Changes in VMware vSphere 5

Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.

Silicon Alley Insider's Dan Frommer and Kamelia Angelova presented this chart of Microsoft's profits on Feb 10, 2010

Microsoft’s Overlooked Innovation

It’s fun to bash Microsoft. It’s easy, too, with Apple solidly conquering the high end of the PC and mobile markets and Google’s command of the Internet. But how fair are these articles skewering Microsoft, such as “Microsoft’s chronic lack of innovation” published today at Techworld? I suggest that Microsoft innovates as well as, if not better than, any other massive company. But no one innovates like an outsider.

Today's storage arrays live in the fat middle of the market, striking a balance between capacity and performance

The Fat Middle: Today’s Enterprise Storage Array

Ask any project manager if it’s possible to deliver something that is fast, good, and cheap, and they’ll laugh. The phenomenon known as the Iron Triangle limits just about everything in the world from meeting all three conflicting requirements. Yet, for the last two decades, enterprise storage array vendors have been trying to deliver just this. How’s that working out?

This Is Storage

Why I Am Biased Against FCoE

I am biased against FCoE because it’s too new to be blithely and broadly recommended for production enterprise use. That’s all. Yes, the standards are standardized and there are products extant. But that’s not enough for me.

The Prime Directive of storage: Do not return the wrong data!

The Prime Directive of Storage: Do Not Lose Data

People call on storage devices and systems to do lots of things, from accelerating I/O to copying and sharing data. But at the heart of it all, storage arrays really have just one job: Do not lose data!
