Hot on the heals of the recent Arduino upgrade (replacing the ATmega168 microcontroller in the Deumilanove with the slightly bigger ATmega328), comes the announcement of the new Arduino Mega. 2k RAM -> 8k RAM, 32k program memory -> 128k program memory. Woot!
A New York Times article today reports on the results of a study of charities.
Apparently people who give money online do not come back.
I find it strange that the article does not mention at all that the electronic payment systems in many charities are a mess, which is my experience. According to an article in the Communications of the ACM , a significant factor in choice of online retailer is users’ trust of the website. People will knowingly choose a more expensive offer from a web site they trust (e.g. Amazon) over a cheaper offer from an unknown or less trustworthy site. I’m not saying that charities are untrustworthy, but I do think that poorly designed payment interfaces which ask for way too much information appear more untrustworthy than well designed payment interfaces which only ask for an appropriate amount of information. This may explain why people prefer other ways of giving in preference to using a website.

Cover on the new California Avenue, Northbound platform, with the word “ELECTRIC” spot-welded into the plate.
An opportunistic iPhone photo, I think it could use a little post processing. But the subject has an interesting combination of smooth, regularly-patterned, metal with the rough spot-welded lettering and little balls of metal, frozen as they tried to escape.
I upgraded. It was a pain. There is an “upgrade” option in Tools now. Next time I will use this.
Just trying SnapTell on the iPhone. Very effective, How does it work? Image recognition?
