Switch Day 58: Ten Pros and Cons of the MacBook Pro

August 11, 2008 by Stephen 4 Comments

I’ve now been a Mac user for two months. Since I switched primarily to get access to Apple’s excellent hardware, I thought I would issue an update on my observations about it at this point. I should note that I’m limiting this post to the hardware (maybe I’ll cover OS X some other time), and […]

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 Four Horsemen of Storage System Performance: The Rule of Spindles

August 25, 2010

Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.

Ten Terrible Apple Products

June 14, 2012

I’m often accused of being an Apple fanboy. While it’s true that I love my vast selection of fruity products from Cupertino, I’m not blind when the company makes mistakes. In fact, I think Apple’s mistakes are as enlightening as their successes: They reveal a company that is fallible, sometimes learning but often allowing the junk to rot far longer than other companies would.

Defining Failure: What Is MTTR, MTTF, and MTBF?

July 6, 2011

Most computer industry vendors use the term â€œMTBFâ€ rather indiscriminately. But IT pros know that systems do not magically repair themselves, at least not yet, so MTTR and MTTF are just as important!

Scaling Storage Is Hard To Do

June 4, 2013

Data storage isn’t as easy as it sounds, especially at enterprise or cloud scale. It’s simple enough to read and write a bit of data, but much harder to build a system that scales to store petabytes. That’s why I’m keenly focused on a new wave of storage systems built from the ground up for scaling!

Edward Snowden Is Right: We Must Protect The Internet

March 19, 2014

Edward Snowden, NSA whistleblower, appeared at TED2014. His video, embedded below, must be watched. You may think he’s a hero or you may think he’s a villain, but he’s unequivocally right about one thing: We must protect the integrity of the Internet and online communications or we risk disrupting the world economy and all of our lives.

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.

Sony NEX-5 Camera Review

September 15, 2010

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.
