Editor: Meet io9 contributor Lisa Katayama. When she's not blogging about robots and futurism, she's spreading the word about how to GTD in the most unexpected ways. Here's a sampling of a few clever tricks you'll find in her new book, Urawaza.
When it comes to life and getting things done, we like to do things a little differently in Japan. When I break a glass in the kitchen, I don't use my vacuum cleaner to clean it up; I use a slice of bread. When my socks become dirt-stained from running in a muddy ravine, I don't pour bleach on them; I stuff them with marbles. And to save space and money, I have never bought a document shredder. I just stuff incriminating documents in a stocking and toss them in the washing machine.

Photography web site Photojojo details how to get crisp, beautiful prints from your digital photos with Photoshop's Unsharp Mask. What's the point of sharpening, you ask?

Digital cameras have a fixed grid of pixels, each of which can only capture one colour or shade at a time. Say you take a picture that has a sharp edge between black and white... The single pixel that records that hairline edge can only record one colour, so it renders it as grey. What we think of as sharpness is actually the contrast we see between different colours. A quick transition from black to white looks sharp. A gradual transition from black to grey to white looks blurry.

The How-To Geek blog posts a truly helpful guide to figuring out what's causing Internet Explorer 7 to slow down, particularly on Windows Vista systems. Starting with running IE7 in safe mode, the guide is a boon for anyone not particularly tweak-savvy as it moves through disabling add-ons, confusing options boxes, and all the way to disabling auto-tuning, plus the ultimate fix—unplugging and re-plugging your router, of course. Regardless of skill level, it's a good forward for anyone you know who can't/won't install Firefox and is tired of browsing the Internet at slug-like speeds. (Original auto-tuning post)

Drop for drop, colognes and perfumes are some of the most expensive liquids around, and yet they can wear off before you step out your door. The TipNut blog suggests that moisturising the area where you'll apply the strong stuff—like with petroleum jelly or any non-scented moisturiser—helps lock in its strength longer than spraying onto dry skin. Combine that with another hint that pulse points are a scent distributor, and your eau de toilette just might earn its keep for the night. Hit the link for more advice, and feel free to offer up your own fragrance suggestions in the comments. Photo by Here in Van Nuys.

Portfolio magazine has a great guide to the realm of higher-end teas, with an introduction to different varieties and age-old wisdom (along with some new-age connoisseur-style advice) on how to best prepare and enjoy the lower-caffeine pick-me-up. I was surprised to see this tip amongst the offerings:

Experts say that you should use boiling water for black tea. For more delicate green or white tea, Sebastian Beckwith, co-founder of the Connecticut-based specialty-tea seller In Pursuit of Tea, suggests letting the water cool for a few minutes. "You lose a lot of flavour if you put boiling water on white or green tea," he says.

Olympic gold-medal-winner Ryan Lochte trains a lot harder than you or I do when he's in the pool, but anyone who uses swimming as part of their fitness routine can pick up a few tips from him, whether on stroke technique or general training suggestions. Among them is a suggestion to create artificial "races" you're aiming to win, or personal records you have to break. From Locthe's advice:

The Just a Guy Thing weblog shares insights into the selfless act of tipping your waiter, your cab driver, the dealer at the casino, or your stylist. A rule of thumb:

Hand over the tip with your palm facing down and shake hands with the person you are tipping, simultaneously placing the money in their hand. What you want to avoid doing is waving the money around and making a big deal of it.

The Tipnut mailbag pulls in an idea for avoiding a problem that drives some people (including a certain wife of mine) insane: Keeping the sponges and clothes used for really dirty work separate from those you run over your eating implements—especially if you buy same-colour sponges in bulk. To do so, use a knife or scissors to nick a corner off the grimy ones (presumably when they're dry). This could also prevent getting counter/surface-cleaning chemicals and grime into the same sink as your dishes, though perhaps disinfecting your sponges in the microwave could prevent that as well.
