Hiding or censoring part of an image through obfuscation is as easy as selecting the area in Photoshop and applying the Pixelate->Mosaic filter, but what if you don’t have an image editing program at your disposal? If you’re seriously paranoid about your privacy on the Internet, there’s a new service called PhotoHide that helps you quickly add these pixelated areas to any photo. Everything is done through the web browser, and you can download the final image once you’re done.
Doing this to every single photo of you on the Internet would be ridiculous, but you might find it useful for more reasonable applications (e.g. hiding your house or license plate number in a photo).
One of the big advantages of digital photography is that EXIF data is embedded into your images, allowing you to easily learn when and how (and more recently where) a particular photograph was captured. If you still enjoy shooting film, then a solution is to jot down notes about your photography while you’re shooting. The “Field Notebook” is a nifty little notebook published by Etsy user fabriKateShop you can use to record “EXIF data” by hand — especially useful for when you’re taking a film photography course. You can find them for about $12 each over on Etsy.
The Flashkus by Art Lebedev is a cheap, disposable, and environmentally friendly cardboard USB stick that might one day make sharing event photos with friends much easier and cheaper. While many websites are geared towards photo sharing, transferring gigabytes of data to friends is still difficult to do via the Interwebs, so people often choose to burn DVDs or use pricey USB drives. The Flashkus would make the process easier by allowing people to simply tear off a USB drive, dump photos onto it, scribble a note onto the front, and hand it off to their friends. Once the photos are downloaded, the drive can be reused or thrown away.
It’ll be available in 4GB, 8GB, and 16GB but currently seems to be in the concept/design stage. Hopefully Art Lebedev adds it to their online store soon.

External hard drives are a convenient way to store your digital photographs, but they have finite lifetimes and eventually fail. Failing drives have a number of distinctive sounds that can warn you and give you some time to start a data-exodus to a healthier hard drive. Datacent, a data recovery company, has a useful page on which you can listen to some of the most common “bad drive sounds”. These are categorized by manufacturer, and include things like stuck spindles, disk heads crashing, accessing bad sectors, and bad bearings. If your drive makes any of these sounds while your photographs are still accessible, begin evasive maneuversimmediately!

You can see sun positions at sunrise, specified time and sunset. The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon. The colors on the time slider above show sunlight coverage during the day.

Tag clouds are a neat way of visualizing what content is about, and Tagerator is a simple program that generates them for your Flickr photo tags. Created by Jeremy Brooks (the guy behind SuperSetr), the simple Java app will run on any computer that has Java 1.6 installed. Besides its ability to generate the tag clouds for you, it stores the tag information gleaned from your account to disk, allowing you to use the tag/count information however you’d like.
