Clever iPhone app prevents calculator pR0n


A tweet earlier today pointed me to an iPhone calculator app that really got me laughing, as well as taking me on a trip down memory lane.

When I was in high school, calculators were expensive (US$200 for a six-function calculator with memory, for example) and just starting to make it into the hands of students. In those more naive times, anything that could be construed as even mildly suggestive got a lot of chuckles. One of the more amusing pastimes was to perform certain calculations that would come up with a result like 5318008 or 3104558 which, when the calculator was turned upside down, would spell a "dirty word."

Well, TLA Systems wants to make sure that its PCalc RPN [iTunes Link, US$9.99] and free PCalc Lite [iTunes Link] calculator apps for iPhone are used only for good purposes, so they've built in a special smut filter that will block these words when the calculator is turned upside down by displaying the word "CENSORED." Their blog entry is very tongue-in-cheek, asserting that they developed the filter to avoid getting a 17+ rating in the App Store.

Personally, I think TLA Systems developer James Thomson is just brilliant at getting blogs to write about his products. Well done, James!

Leopard Love: Apple boosts Calculator

OS X's Calculator application is something I basically ignore. Between Spotlight and Terminal's bc, I rarely if ever use it. So it was a pleasant and welcome surprise when TUAW reader Roberto Mateu gave us a heads up that Leopard's calculator was updated with better RPN support.

Calculator has done RPN for some time--if you're still running Tiger, you can see the old version by selecting View > RPN for any of the three calculator types. Under Tiger, the = button changed to Enter and that was about it. Leopard has updated the RPN calculator by adding multi-line entry so you can see your stack as it grows. It's a much nicer way to use RPN and TUAW heartily approves.

Tip of the Day

To get an instant map to any address, just go to your Address Book and right click on the address field of any one of your contacts and select "Map Of." The address will then be revealed in Google Maps on Safari. You can do the same if a data detector determines there is an address in an e-mail in Mail.
