extra88 writes: Heise online reported that Sun has released their OpenDocument Format (ODF) plug-in for Microsoft Office 2000, XP and 2003. The plug-in allows Microsoft Office (for Windows) users to open ODF files and save their work in ODF formats used by OpenOffice, StarOffice, and other programs. According to the ReadMe, the plug-in adds "ODF Text Document (*.odt)" as a format to Word's Open and Save dialogs and adds Import and Export options to Excel and PowerPoint. Support for Excel and PowerPoint in the Microsoft-sponsored OpenXML/ODF Translator Add-in for Office is yet completed and that Add-in supports only Office 2003 and 2007.

And they will be touring the country with the vehicles next year to test the consumer acceptability of the vehicles. This could be good news for those beginning to feel the oil crunch, to quote the article: "...every team member has a future in auto engineering. And for a North American auto industry under siege, that makes Challenge X a bright beacon of hope for the future.""

Submission + - A bus built like a prius?

140Mandak262Jamuna writes: Electric motors built into the hubs of car wheels can improve the efficiency of electric/hybrid vehicles, according to IEEE Spectrum.

The CEO of the company making such wheel-hub motors plugs thus: A motor housed inside a wheel hub can shunt up to 96 percent of the torque it generates directly to the patch of tire that touches the road, With a conventional drive train, roughly 20 percent of the power generated by the motor is lost to friction.

Hype and plugging aside, the company has actually built two buses that can run for 1 hour without using the diesels. It has two electric motors built into the hubs and has some pretty heavy duty batteries. In the stop-and-go city traffic the regenerative braking gives big boost to the efficiency. Still, these buses cost 250 K$ more each, and they save some 20 K liters of diesel a year or some 60 K$ a year.

IANAFinExprt but it looks like it is cost effective if the useful life of the vehicle is more than 5 years and we can assume faster than inflation rise of gas/diesel prices.

Journal Journal: Choke points for spam

Journal by ILikeRed on Saturday February 17, 2007 @06:53PM

A large problem with spam is the collection of zombie systems (mostly Microsoft home computers) on residential broadband lines that act as relays for spam. Most of these users have simple firewalls supplied by their broadband providers that they never really configure that provide DNS proxy services, among other services. Is it not about time to start pressuri

Submission + - Geo-engineering to fend off climate change

moon_monkey writes: While cutting greenhouse gases might be the best way to halt climate change, it's reassuring to know some scientists are already thinking about ways to combat fend off runaway warming if this doesn't work. NewScientistSpace has an interesting blog post about some pretty crazy-sounding ways for combating climate change. These include pumping sulfur into the atmosphere, sending thousands of tiny mirrors into orbit and even painting all our roads white to reflect the Sun's rays. Could this be the next X-prize?

My youngest sister (9 years old) was fascinated to know how I had done it and seems quite keen to want to know more. I know that some people say that children and fickle at that age but I'm keen to let her have the resources that she needs to learn more about programming if she wants to. Does anybody know about any good resources for children to learn more about Java?"
