Last month I brought you details of Microsoft Mathematics, a free program for anyone who's trying to study or teach maths. Almost 21,000 of you clicked on the link to my story, making it one of the most popular Hot Find items ever.
For the holiday, I mozied down to Home Depot to get some replacement lights and to generally just walk around. I noticed more green products on the shelves and was surprised to see this WaterSense Glacier Bay toilet with Niagara’s Flapperless flush system selling for $88. On the way out, I was given a copy of The Green Guide with these 10 suggestions for saving money, energy, and water.
This week’s “Change the World Wednesday” challenge covers a topic which is close to my heart. It’s all about swapping disposable items for reusable ones. This means we’re moving up the 3Rs ladder, away from recycling and on to reuse - yipee!
Whether it’s a prototype, a single serving site, or something more complex, it’s always a thrill to see even the simplest app up on the web. Adding that “appness” brings life to what were previously just pages on a server.
Soon, we’ll probably be seeing Lithium Iron Phosphate (LiFePO4) batteries being used in most electric cars and bikes. This new battery type is set to dominate the market. Based upon lithium ion technology, LiFePO4 batteries offer many advantages over lithium cobalt dioxide (LiCoO2) batteries which are commonly used in laptops, mp3 players and cell phones.
HTML 5 introduces new elements to HTML for the first time since the last millennium. New structural elements include aside, figure, and section. New inline elements include time, meter, and progress.

Nvidia’s about to up to the ante again in the mobile processor race.

As LTE continues to gain momentum around the world, and especially in the U.S., it looks like Sprint might be switching 4G gears. During a roundtable discussion at Mobile World Congress, Sprint’s senior vice president of networks, Bob Azzi, said that the carrier will watch how many of its customers migrate from EV-DO to mobile WiMAX over the next 4 to 6 months and then evaluate the best way to use its existing spectrum.

Machines first out-calculated us in simple math. Then they replaced us on the assembly lines, explored places we couldn't get to, even beat our champions at chess. Now a computer called Watson has bested our best at "Jeopardy!"
Who would think that you'd learn about an eco-friendly product at a birthday party? Well, with my family, you never know where the conversation will lead us. Last weekend at our youngest family members party, my sister told me about this new printer they just got at work. "It uses crayons instead of toner," she said.
