I watch for cheap prices on Lens Pens, as I keep them on hand for cleaning eye glasses and cameras on the run. Anything in the sub $5 range catches my eye.
The lens pen sports a retractable brush at one end and a cap-covered, lint-free soft wiping element at the other. It is compact and protected enough to live in a pocket or glove box without collecting ruinous amounts of dust. Number of useful cleanings per pen varies on the size of and what I'm cleaning, but I tend to get quite a lot of careful use out of them. Grease and oil that gets picked up by the wiper don't get cleaned off, so over time you'll need to replace the pen.
I clean big lenses at home with a blower, lens paper and cleaning solution if needed. It'd be a waste to use one of these. In the field, however, this little guy shines.

Periodic Stats is a dead-easy web-based Periodic Table to click around, showing all the stats and the history of each element. The only thing missing are illustrations of each one! [via Reddit]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass.

If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
