Correcting autofocus errors with AF fine-tune

Autofocus systems, as good as they are these days, aren't perfect. A modern camera's AF is a complex opto-electro-mechanical system, and while they are manufactured to incredible tolerances, there is usually some final calibration that must be done by the photographer to account for the quirks of his particular equipment.

How to set up a new Windows laptop: Nuke it from orbit

Microsoft Windows is actually pretty solid these days, notwithstanding the occasional hopelessly bone-headed interface design decision (Win8 Metro, anyone?). The NT 6 kernel family that underpins Vista, Win7 and Win8 is, now that Vista's teething pains are overcome, pretty slick and reliable.

Cranking that air conditioner is more expensive than you think

We've had a heat and drought wave in southern Ontario for the last few weeks. The grass goes "crunch" underfoot, there's been virtually no rain for a month, and the thermometer's been consistently in the high 20s to low 30s- and, with humidity at 70+ percent, it feels a lot hotter.
