New Ice Structure Could Help Seed Clouds, Cause Rain 100

Posted by ScuttleMonkey from the no-more-scaring-the-cows dept.
ScienceDaily is reporting that a new ice chain structure may provide a better method for seeding clouds and causing rain. "Ice structures are usually built out of simple hexagonal arrangements of water molecules and this hexagonal building block motif is easily observed in the structures of snowflakes. However, during their studies Dr Angelos Michaelides and co-workers from the Fritz Haber Institute, Berlin, and the University of Liverpool have discovered a natural nanoscale ice structure formed of pentagons."

Interesting Uses For a USB LED Screen? 403

Posted by kdawson from the your-messge-here dept.
Hogwash McFly writes "My boss gave me one of those USB-powered red LED scrolling displays as a Christmas gift, and while cycling the usual 'I read your emails' and 'ID10T Error' messages will be entertaining for a day or two, I was wondering if it could be put to more constructive uses. The configuration file is plaintext and supports different scroll speeds, flashing, bitmaps, and WAV sounds. The font is defined as 5x5 pixels per character, also stored in plaintext as 5 hex values, one for each vertical line of pixels. A dynamically generated message could prove useful in my day-to-day work on the helpdesk, but are there any interesting uses beyond network notifications and news feeds?"

PHP Gets Namespace Separators, With a Twist 523

Posted by Soulskill from the or-maybe-more-of-a-slant dept.
jeevesbond writes "PHP is finally getting support for namespaces. However, after a couple hours of conversation, the developers picked '\' as the separator, instead of the more popular '::'. Fredrik Holmström points out some problems with this approach. The criteria for selection were ease of typing and parsing, how hard it was to make a typo, IDE compatibility, and the number of characters."
