Given the 40 degree difference in the sun angle between Summer and Winter, would it make sense to change the tilt on the panels to optimize the angle for the two seasons?
Maybe a screw jack could lift the top of the panels as winter approaches, then lower them again as you move into summer?
It's not like snow or ice would be a problem and you could probably get the screw jack from an old satellite dish (or Boeing surplus!).
Teachers are incredibly undereducated when it comes to technology.
That's a pretty broad brush you're painting teachers with. Don't know about your schools, but my town has computers in the classrooms, and teachers that, for the most part, know how to use them to help them get their jobs done.
Many of them have heard about open source software, and the schools installed Firefox on the PCs this year, in acknowledgment of IE's susceptibility to malware.
However, getting back to the topic of the article, this whole episode shows what happens when we let our emotions get in the way of thinking, and underlines the rule about writing emails: don't do it when you're upset or angry, you'll only regret it later. Looks like these two adults learned that lesson the hard way, but at least they learned it.
I'm not a pager guy, but have used them and know pager guys. Also, have played with old pager gear as a staring point for some ham radio projects.
Pagers used high power (300 watt) transmitters, and if you wanted to cover a decent area, several of them, synchronized to prevent distorted signals in the area where their coverage patterns overlapped. They were known for their tendency to interfere with other systems, no matter how well they were maintained. It was an expensive way to make not much money.
Profit margins were low, and churn was always a problem. Companies went in and out of business, larger companies consolidated the smaller companies, but, in the end, Nextel and cellular technology gave you two-way communication at essentially the same monthly rate.
Basically, paging companies were made economically obsolete by advances in technology. There are "micro" paging systems still in use at restaurants, hospitals and companies, but the high power transmitters on the hill are pretty much gone, replaced with cell sites.
Records show it was a "test account" assigned to the information technology section of the attorney general's office, said Department of Public Safety spokesman Thomas Hunter.
Brindisi later said investigators have confirmed that Wurzelbacher's information was not accessed within the attorney general's office. She declined to provide details. The office's test accounts are shared with and used by other law enforcement-related agencies, she said.
"IT Test account". Shared by a bunch of different offices. Looks like whoever did the search was smart enough to muddy the waters a bit.
Cray Research merged with SGI (Silicon Graphics, Inc.) in February 1996. In August 1999, SGI created a separate Cray Research business unit to focus exclusively on the unique requirements of high-end supercomputing customers. Assets of this business unit were sold to Tera Computer Company in March 2000.
Tera Computer Company was founded in 1987 in Washington, DC, and moved to Seattle, Washington, in 1988. Tera began software development for the Multithreaded Architecture (MTA) systems that year and hardware design commenced in 1991. The Cray MTA-2â system provides scalable shared memory, in which every processor has equal access to every memory location, greatly simplifying programming because it eliminates concerns about the layout of memory.
The company completed its initial public offering in 1995 (TERA on the NASDAQ stock exchange), and soon after received its first order for the MTA from the San Diego Supercomputer Center. The multiprocessor system was accepted by the center in 1998, and has since been upgraded to eight processors.
Upon the merger with the Cray Research division of SGI in 2000, the company was renamed Cray Inc. and the ticker symbol was changed to CRAY.
Big surprise, huh? Companies were pulling a fast one to save a bit on salaries and benefits...and to get employees who would be "easier to manage" (i.e.: scared to complain, lest they lose their job and have to return home).
This is the closest thing to reality I have read on the subject for a long time.
When landing and taking off (the absolute worst time for Something Bad to happen to the airplane instruments), shutting down all the random RF emitters near the instruments makes lots of sense.
Even more so, when you understand how the glideslope, localiser and marker beacons are transmitted and displayed. These are (unless you have very new equipment, and even if you do, the old analog stuff is still your backup if the computer fails) amplitude-modulated analog signals that use tones and their relative phases to move meters in the cockpit. They don't respond well to random bursts of (relatively) high power RF. Just imagine what that catchy little "tickety-tick" that shows up on your car radio just before your cellphone rings...would do to a display trying to show you the phase or amplitude difference between two audio tones.
I, for one, don't want *anything* interfering with the stuff that's helping my pilot find the exact right patch of ground underneath all those clouds, rain and fog. I'm guessing most of you are with me on this one.
Cellphones off for takeoff and landing, please folks. It makes much less difference at 10,000 feet and above. The cell phone towers may get confused, but the have the same problem when you're at the top of a 16,000 ft mountain, and they're not prohibited there, so I think that's a phony reason for the prohibition.
There have been documented cases where pilots have had bogus navigational instrument readings which have gone away when passenger cellphones have been located and turned off. Pilots aren't RFI troubleshooters, but they are pretty bright and have good basic technical knowledge, so when I read reports like that, I believe them. That's not to say that the cellphone might have been out of the ordinary in some way, but then again, maybe it wasn't. I prefer not to take the chance. Does it matter? Maybe not, but do you want to bet your life and the lives of everyone else on board? Personally, I'll wait until we land to make that phone call.
Well, every time you use a licensed player to play a DVD, you (legally) circumvent or bypass the encryption (otherwise, you could not view the DVD you paid for)
It comes down to the term "circumvent", which is defined in the DMCA as:
"...to `circumvent a technological measure' means to descramble a scrambled work, to decrypt an encrypted work, or otherwise to avoid, bypass, remove, deactivate, or impair a technological measure, without the authority of the copyright owner..."
I call your attention to the phrase "descramble a scrambled work...without the authority of the copyright owner" in the above quote.
Does viewing a DVD under Linux, for example, using a non-approved decrypter, constitute circumvention, or, have you, by virtue of your purchase of the DVD, received an implicit license from the copyright owner to view the content? Did you receive a license to view the content *only* on licensed playback devices? If so, where is that restriction listed on the media you purchased?
To put it succinctly: we're pissed off, too. I'm not at all happy about what's been happening to our civil rights, our constitution or our country's image in the world. The last eight years have been a boon to the corporations and a disaster for the rest of us. Our elected officials are either too lazy, too stupid, too scared or too much beholden to the corporations. It is on their watch that the PATRIOT act, the TSA and the DMCA have been passed.
So, it's not just the young who lose, it's all of us. Some of us old geezers feel just like you do.
And by the way, you're damn right we have a sense of entitlement. Entitlement to do what we want, as long as it doesn't hurt anyone else. Entitlement to human rights and fair use of copyrighted material. Entitlement not to be treated as suspected terrorists every time we board an aircraft.
Bitter? No, just angry, and hoping more people get that way. Democracy only works if you make it work.
I'd like to see them visit a family with a nerdy kid who uses a MythTV box.
"Yeah, I used to use Windows, but it wouldn't record all the shows I told it to -- something about a "broadcast flag content protection error". Ever since I replaced it with Myth, I've had no more problems.".
So...16 satellites in LEO, meaning intermittent coverage, plus they will need spares and steerable ground antennas. I'd like to see an article with all the technical details, but it doesn't sound practical for providing continuous high bandwidth links...and it seems pretty expensive for covering only a belt around the equator.
Worked on a project to handle just this problem. Shielding fabric allows you to view and manipulate the phone, while preventing it from connecting to the network. A standard anti-static bag works pretty well, too...just make sure you get a good inside-to-inside seal.
It's fine to call up and complain about fraudulent charges, but like it says in the credit agreement, your rights aren't preserved unless you make a written complaint, stating certain facts.
If you do make a written complaint, you're protected by the laws regulating credit cards and they can't ignore your complaint, need to respond within (some number) of days, and in general, pay more attention to the issue.
So, write it all out, send the letter certified, and keep a log of calls and letters. That way, when you call back, you have facts and names.
I worked for a company that had *exactly* that policy.
My way of remembering passwords was to pick a word, take two consecutive letters of that word, represent them as their phonetic equivalents (A = alpha, B = bravo, etc.) and separate them with a symbol (I used "%" every month).
Next month, take the next two letters in the word, when I got to the end, I'd use the first two letters again. By that time, the "no repeats" buffer had overflowed.
Easy to remember, easy to create, never had any trouble.
900 MHz is a frequency at which body tissue absorbs RF energy. And you're holding the antenna up to your head.
Keeping RF away from your body has always been good practice. Current ARRL and FCC guidelines for RF exposure suggest that 5W near the body is about as much as you should permit. I'd want to be 10 to 100 times lower than that for regular exposure, and I'd also be concerned if the frequency was one that's absorbed well.
I use hands free whenever possible and keep my calls short.

Good luck, Steve. I think you have lost touch with your intended customers.

All the fuel injectors I have ever seen are fed by metal lines. Creating an electric field through a metal line is going to be a neat trick.
MediaSentry is having a bit of a problem with the fact that they are not licensed as a private investigator in any state where RIAA has brought suit.
They have additional anti-copy stuff on them and they don't usually play or rip well under Linux.
VLC may be able to play them but no guarantees.
...but minus the fistful of dollars...

- a good way to keep from exposing yourself to RF
Minuses:
- prevents the phone from communicating with the base station.
