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.

Things are getting awfully complicated, aren’t they? The custom parallel CPUs, proprietary communications networks, and encrypted data ports require extensive training, special tools, and a computerized reference library to comprehend, much less debug. And the manufacturers, who derive much of their money and differentiation from warranties and authorized repair centers, are loathe to see independent shops get a piece of the action.
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.
Last year, I posted two articles about Apple’s OS X 10.6 “Snow Leopard” and its new 64-bit kernel. The upshot was that, although just about every Mac made since mid-2008 is 64-bit capable, only the Xserve boots in 64-bit mode by default. Since my main computer is a glorious 27″ iMac that runs 64-bit Snow Leopard perfectly, I decided to permanently set it to boot this way. Here’s how you can set your Mac to boot 64-bit Snow Leopard, too!
Apple released version 4 of their iPhone OS iDevice (iPhone, iPod Touch, iPad) OS last month after a grand WWDC unveiling. Although there are many changes and new features, not all are as obvious and noteworthy as multitasking, home screen folders, and background audio. After working with iOS 4 on an iPhone 3GS and iPhone 4 for a month, I thought I might highlight my favorite hidden features. Did you know these existed?
Apple recently announced their “free iPhone 4 case” program. In addition to the Apple-brand bumpers, the company is offering a number of third-party cases. But which is best? Here’s my rundown of the options, as well as my personal pick.
Since all the cool companies are offering capacity guarantees these days, I thought I might as well throw my hat into the ring and offer one, too. Starting now, I guarantee any takers an easy plan to write 50% more production data to your existing storage environment. Even better, I’ll do it with no additional hardware or software to purchase and install and no complicated terms and conditions. You won’t even have to delete anything, but if you do I’ll guarantee double your data! And I’ll only charge 50% of the deferred storage hardware and software spend, and if I can’t do it you pay nothing. What have you got to lose?
The buzz about Fibre Channel over Token Ring has built rapidly over the last week. Industry experts like Greg Ferro, Denton Gentry, and Joe Onisick have weighed in, and the Packet Pushers Podcast featured the news in show 12, “Get on the Ring!” Some have called out FCoTR as a foolish hoax, but the FCoTR phenomenon is not foolish. Indeed, FCoTR gives everyone in the industry the chance to reevaluate the current state of the art and has exposed real weaknesses in the Ethernet-centric future of the data center.
Industry veterans fondly remember the LAN wars of the early 1990’s, when a diverse set of excellent data link protocols competed for dominance. Although the victory seemed to have gone to Ethernet, industry insiders are looking for a resurgence of better alternatives. One technology, Token Ring, is undeniably superior for transporting modern protocols, especially Fibre Channel for storage. Let’s take a look!
Unless you’re “in the know”, terms like “layer 2” can seem mysterious, making it all the more plausible when someone touts the benefits. It seems logical: “Bare-metal” communication must be better, faster, and cheaper than higher-level “everything over IP” approaches, right? But it’s not quite that simple.
