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

July 24, 2015 by Stephen 8 Comments

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…

Mac Users, Secure Your Stuff in Dropbox

July 5, 2011 by Stephen 8 Comments

Encryption is an important tool for individuals regardless of what they’re storing. Given the recent security failings of Dropbox, I highly recommend using methods like this to secure your important data before using the service!

Review: 1 TB Seagate Expansion Portable USB Drive (ST910004EXA101-RK)

September 3, 2010 by Stephen 2 Comments

The Tech Field Day events I organize generate a massive amount of HD video content, and moving half a terabyte or more of data is a real issue. We had been using luggable desktop drives from Western Digital and Seagate, but preferred a smaller, lighter, USB bus-powered portable solution. The Seagate Expansion Portable USB drive we bought this week packs an amazing 1 TB of capacity, but our experience with the product was mixed at best.

How To Move OS X Time Machine Backups To A New Disk

July 26, 2008 by Stephen 33 Comments

It turns out that you can move Time Machine backups easily, with included OS X tools, and without breaking anything. My old backups are still visible, and I have another 40 GB to work with. Read on for the details!

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.

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!

The Prime Directive of Storage: Do Not Lose Data

December 12, 2014

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!

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.

What More Could Alan Turing Have Accomplished?

October 7, 2012

Many of you have probably heard the name of Alan Turing, but most of those probably don’t appreciate the extent of his contributions. To say that he invented the modern world is an overstatement, but he did dream up the computers we see around us today, and helped win World War II in the process. But the story of Alan Turing is as much about exclusion and defeat as it is of genius.

Making a Case For (and Against) Software-Defined Storage

January 9, 2014

Everyone is talking about â€œsoftware-definedâ€ everything lately, so it was only a matter of time before industry buzz turned to software-defined storage. VMware and EMC really stoked the flames with a constant barrage of marketing directed in this direction. But how exactly do you software-define storage? And what does this mean?

Why Are PCIe SSDs So Fast?

June 12, 2013

The world of storage can be confusing, with obscure terms hiding massive differences in technology and performance. Such is the case for the latest PCI express SSDs: They are much faster than traditional SAS or SATA SSDs, but many aren’t sure exactly why. In this article, I will try to explain the real difference.

The 2018 iPad Pro is a Beast!

November 9, 2018

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!

Marketers: Fudging the Meaning of Buzzwords Matters (To You!)

December 2, 2015

Too many marketers and salespeople play fast and loose with words, but they’re only hurting themselves. Improper usage is embarrassing and causes a loss of credibility with the people they most want to reach. It would be wise to spend a lot more time being correct and a little less time jumping on bandwagons and buzzwords!
