Comment Re:Is the new android fine? (Thinking of buying) (Score 1) 132

I'm looking to buy a new phone in a few months. My current Nokia 6300 has lasted for almost 3 years, and is beginning to act a bit weird at times.
I had a look at the Nokia N900 a few days ago and was amazed at the price compared to the specifications and the price point of other smartphones. Qwerty keyboard, 800x480 display, Maemo 5.
Here in Denmark I can buy a new and unlocked for 375 EUR, though I'm tempted to find a used one on eBay -- the price there starts around 200 EUR for a slighty used.

I know that there are demonstrations in some locations around Europe, but calling them "riots", that's a bit of a stretch.
I'm in Denmark. Even if my backyard covered Sweden, Norway, Finland and Germany I haven't heard about any events that would qualify as a riot.

If NY cab drivers stop working in protest of something, is that a riot as well? A riot across the USA?

Note that the AP "blurp" doesn't even call it riots, only protests.

'Wi-Fi Illness' Spreads To Ontario Public Schools 663

An anonymous reader writes "Readers of Slashdot might be familiar with Lakehead University's ban on WiFi routers a few years ago in Thunder Bay, Ontario because of 'health concerns,' a policy apparently still in effect. Now it seems a group of concerned parents in a number of communities in Ontario have petitioned the local school boards over similar concerns at public schools, where their kids are apparently experiencing 'headaches to dizziness and nausea and even racing heart rates' — symptoms that appear only when they are in school on weekdays, not on weekends at home. 'The symptoms, which also include memory loss, trouble concentrating, skin rashes, hyperactivity, night sweats and insomnia, have been reported in 14 Ontario schools in Barrie, Bradford, Collingwood, Orillia and Wasaga Beach since the board decided to go wireless ...' Besides Wi-Fi signals, could there possibly be any other logical explanation for kids having more symptoms of illness on school days than at home on weekends or in the summer?"

From the summary:

and some off-the-shelf air quality sensors (about $10 each)

From the article (sorry, Instructable):

- Air Quality Sensor from Figaro (I recommend the VOC or the diesel/exhaust sensor, $10/$20 each)

I guess it was just too hard to copy/paste two prices.

The article is just as bad. I mean, this is Carnegie Mellon University. How's this for science:

Data sheet for both sensors suggests 48 hours of preheat to make the elements most stable. I've run them for about 24 hours and it seemed to work fine.

Oh, so your sensors "seem to work fine". Here's a quote from the datasheets:

[solvent vapor sensor] Standard test conditions: Conditioning period before test: 7 days
[gasoline and diesel exhaust sensor] Standard test conditions: Conditioning period before test: 2-7 days

No calibration whatsoever. Dumbasses.

I hope these wankers create an air pollution scare and the local population starts wearing gas masks to defend themselves from horrendous air quality because the people who'll build this kind of thing has no clue, follows the Instructable without question and makes the same mistakes as the UNI-FUCKING-VERSITY people.

Comment Re:Physics... (Score 1) 226

Found the Wikipedia article on the Lockheed SR-71 Blackbird after reading your comment (last paragraph in "Titanium structures and airframe"):
"To allow for thermal expansion at the high operational temperatures, the fuselage panels were manufactured to fit only loosely on the ground. Proper alignment was only achieved when the airframe heated due to air resistance at high speeds, causing the airframe to expand several inches. Because of this, and the lack of a fuel sealing system that could handle the thermal expansion of the airframe at extreme temperatures, the aircraft would leak JP-7 jet fuel onto the runway before it took off. The aircraft would quickly make a short sprint, meant to warm up the airframe, and was then refueled in the air before departing on its mission. Cooling was carried out by cycling fuel behind the titanium surfaces at the front of the wings (chines). On landing after a mission the canopy temperature was over 300 C (572 F), too hot to approach. Non-fibrous asbestos with high heat tolerance was used in high-temperature areas.[20]"
