Submission + - GE is 3D printing a working jet engine...

lurking_giant writes: GE Aviation's Additive Development Center near Cincinnati has produced a number of firsts... but they are now demonstrating a working jet engine, http://www.computerworld.com/a... (OK, it's sized for an RC model) The engine turns at 33,000 RPM and is made from all 3D metal printed parts.
They used the same EOS M270 http://www.eos.info/systems_so... 3D printer that they use to produce the first and only FAA flight approved hardware, a T25 Pres and temp sensor for use in GE90 jumbo jet engines. http://www.engineering.com/3DP...

Submission + - Data Mining errors can hurt people.

lurking_giant writes: Although I've seen few other reports of this happening, I personally witnessed the emotional distress it causes. My sister and brother-in-law had been receiving phone calls and mailings offering college placement test classes to help improve their daughter's test scores. The callers assume my niece to be a high school junior.

It's apparent they were working from data derived only from birth records, not cross referenced against any other data. It seems to me that competent data mining and cross checking of simple public records could have avoided this situation.

My niece is autistic and although she is of the appropriate age, given her developmental conditions, she will never attend college or even high school.

Instead of celebrating the marginal improvements in my niece's abilities as she grows, my family gets "innocent" calls from people that remind them of just how far behind her peers she really is.

If you work in the data mining field you need to remember how even simple failures or sin's of omission can effect others.

Submission + - "Green" Ice Resurfacing machines fail in Vancouver (nwsource.com)

lurking_giant writes: The Seattle Times is reporting that the Men's 500 meter speed skating was delayed or more than an hour Monday evening by the breakdown of the 2 ice grooming machines at the skating oval. The real story is that the machines that failed were the latest state of the art Resurfice — Fume Free Electric Groomers leased to the Olympics committee. An old propane powered Zamboni had to be brought out to fix the ice. This makes 2 nights in a row with ice re-surfacing machine failures.If you're going to spend twice as much on electric devices to replace non green designs at least test the things first.

Submission + - Another bad battery idea for electric vehicles... (physorg.com)

lurking_giant writes: From an article on PHYSORG.COM, "Researchers from Imperial College London, UK, and their European partners, including Volvo Car Corporation, are developing a prototype material which can store and discharge electrical energy and which is also strong and lightweight enough to be used for car parts. In addition, the researchers believe the material, which has been patented by Imperial, could potentially be used for the casings of many everyday objects such as mobile phones and computers, so that they would not need a separate battery."

Great... Now you can be killed by the rapid discharge of the electrical energy in your car's battery from a fender bender or shopping cart scratch. (Although I would pay good money to see somebody attempt to "key my car" and get electrocuted in the process.) *Note to Carrie Underwood...

Submission + - Mainstream press "Cringes" at Windows & launch (cnbc.com)

lurking_giant writes: "Well... Microsoft has done it again with the youtube Windows 7 launch party video...YouTube video and it's turning the stomachs of even the Mainstream press with it's clueless and campy marketing style. A Washington Post reader was quoted as saying "If Microsoft had been put in charge of marketing sex, the human race would have ended long ago, because no one would be caught dead doing something that uncool.""
