A Nikon lens with double vision

I was most disappointed with the images I obtained during our recent trip to Florida. Many telephoto shots appeared out-of-focus despite the well-regarded image stablilization (vibration reduction) built into the Nikkor 18-200mm f/3.5-5.6G IF-ED AF-S VR DX attached to my new Nikon D90 body on it's debut outing. As was my habit, to protect my investment the lens was fitted with a screw-on skylight filter. I couldn't believe how poor my shots were when viewed on a 24" display: Was the camera (still in warranty) malfunctioning? Had my photographic skills regressed? Could something be wrong with the (now out-of-waranty) lens? Why was the centre of some images sharp, with progressive blurring or even 'double vision' towards the peripheries? These were questions for Nikon to answer.

iPhone 2G on O2 Simplicity contract

If you liked the concept of a new iPhone 3GS but found the contract tariffs and Pay & Go up-front costs unpalatable, now might be a good time to obtain a pre-loved iPhone 2G or iPhone 3G. I have an iPhone 2G which I previously unlocked and used on Vodafone UK, but found myself drawn to O2's offer of unlimited O2 to O2 calls—not to mention avoidance of the need to unlock the device and the hassle around firmware updates that doing so entails. I had to dig around the Interwebs and make a support phone call to discover all I needed to know to get up and running with O2 Simplicity; that knowledge is summarized below. Feel free to contribute any further tidbits!

Swine flu apps pervert free informatics

Information wants to be exploited—and that's generally a good thing. Exploitation has downsides too and these seem to be manifest when you look at the growing epidemic of iPhone apps pertaining to swine (novel, Mexican, or H1N1) influenza that you can pay to download from Apple's iTunes for use on your iPhone. As of today I count nineteen paid apps (in the UK store) and thirteen provided free-of-charge (although these may include paid advertisements). Do we need so much choice? Do we need flu updates on mobile devices at all? What are the risks associated with this expeditious development?

Kayaking with alligators

Our first joint trip to the USA was to NYC; our second was a holiday in Central Florida, which we shared with friends from Jamaica. We did the Disney thing (twice was enough), fulfilled a childhood ambition to visit the Space Center at Cape Canaveral, damaged our hearing on an airboat, went kayaking with American alligators, and got some experience driving in the US.

The dark art of AirPort networking

Until recently I was using the dodgy BeBox supplied by my Internet access provider as both a DSL modem and wireless router. The ST585v6 could create a wireless distribution system (WDS) to extend my home LAN to the attic iMac, but only over insecure WEP. So we bought a new dual-band (2.4 and 5GHz, 802.11b/g/n) Apple Time Capsule, thinking it would simplify connecting to an AirPort Express and at the same time provide wireless Time Machine backups with shared network-attached storage (NAS). In the event fully integrating this new device consumed hours, with victory arriving only after the discovery of occult keystroke trickery—not at all the Apple experience I have come to expect.
