Not necessarily, and in this case probably not. Speed can be determined independent of position. The "expert" probably made the snap judgment initially, only to be corrected later.
And with multiple points logged it's possible to validate by comparing it to the positions if the positions were independently determined.
Some GPS receivers determine velocity ( speed + course ) based on the differences between positions. Others ( better ones ) determine velocity based on the doppler shift in the signal from multiple satellites.
If the original assumption was that speed came from the first method, it is true that it's less reliable. Finding out that the second method is used in this case makes it a different case. Additionally, the velocity determined by doppler can he compared to the delta positions to make sure they are consistent. This only works since the two were determined independently.
The expert's mistake was making a snap judgement about the GPS receiver without examining it first.
Back in 1999 I got a speeding ticket for going 77 mph. I had a quality GPS logger in my car. I knew exactly where I was clocked so I compared the speed at various points leading up to where I slowed down as I got pulled over. My speed reported within 2 seconds from when I was hit with radar was 78 mph. I decided to not fight that ticket.
The ratio might be standard, but pixel count isn't.
1080p is defined as 1920x1080. While Toshiba may have kept the ratio, they shaved the edges off of the full 1080p spec.
They have the cell-based co-processor, HDMI out, dual drives, and a huge screen. All the bits for watching or even editing HD video. After all that they dropped 500K pixels from an 18.4" display when you can get higher resolution screens in 15.4"
There's got to be some upper limit to be called a laptop. I looked at screen resolution first, it's 1680x945. It's an odd size, not as many pixels as some other laptops. Then I noticed the size in inches: 18.4! Base weight: 10lbs.
I don't have a problem with large computers you carry from room to room with a built-in UPS. But at some point it's a desktop all-in-one or something else.
More accurate would be "CD content still readable". CD rot is only an issue if you made too few copies and didn't re-copy to newer media periodically.
If it's really, really important:
--Save the stuff on reasonably reliable, name brand media. Make more than one copy, saved separately. --Make the secondary copies on a different brand media, just to cover your ass. --Copy over to identical media type a year or two later ( save originals ) --Copy/consolidate to the newer, cheaper media ( like CDs to DVDs) when the price on the new media drops a bit. Include drivers, codecs or even a player or two on each piece of media that consolidated several smaller pieces of media ( 5 CDs per DVD for example ). (Save originals ) --Repeat the re-copy to same type of media, repeat the consolidation to newer/larger media.
If original format is getting old or unusual, convert/transcode to newer format in the least lossy format. Save transcoded copies in addition to the originals ( don't throw away your negatives )
With the advent of consumer digital video/audio there's no reason to lose anything. Even saving all these CDs, DVDs, Blu-Ray disks would take less physical space than my Dad's box of 35mm slides that cover the same 20 year period.
I worked in a TEMPEST shielded flight simulator bay in the 80's. The entire place was sealed, shielded. Dual door airlock to enter/exit. Power came in and spun a motor which spun a generator so there were zero wires leaving the room that were attached to any equipment inside the room.
After it was constructed I remember when it got tested and certified. The main bay was all metal walls and ceiling. If they found a tiny RF leak they'd spot weld over it When done the inside walls looked like a set from a SciFi movie with tiny laser burns all over.
In related news, a group of Cub Scounts got a shock when visiting a geocache site, expecting to find plastic figurines from Skippy, the Bush Kangaroo. http://geocaching.com.au/dashboard/au/nsw/
Copy protection can be done to both files though downloaded versions can even have player or user specific protection.
What lack of physical media really does is prevent you from legally sharing your movie. No DVD to hand from friend to friend after you've watched your special edition with all the extras. No disc on the shelf of your library. No disc for Blockbuster or Netflix to rent out over and over again.
Unlike CDs that people listen to over and over again, many many movies are watched just once or twice. That makes DVDs even more attractive to loan out, give away, or sell used. If you disregard illegal extraction and copying DVDs are more attractive for buying and selling used or loaning out than CDs. People can get all the use they would have got out of a purchased copy from a borrowed, rented or purchased used copy.
All those easy abilities to rent, borrow and sell discs legally are killed by downloads. There may be legal ways to share, but that's up to the entity that's providing the downloads, like burning a CD from iTunes.
First, the $1 gallon is the cost of production. Cost to consumer would include the cost of the feedstock, distribution, taxes etc.
And if / when this ramped up, it would be unlikely to use "waste" as the feedstock. Waste is something no one's found a use for yet. If corn stalks and wood chips are suddenly the new source of car juice it will cost more money.
Less cost to produce and uses a wide range of material is good. Dirt cheap, not likely.
There's another company out there doing wall art based on your DNA sample. If I cared enough to spend the money I'd pondered sending them 2 samples, but from different customer names. In theory, the art should have matched.
I'd like to see some consumer watchdog group do this with these guys. Send the same sample, supposedly from different people, then compare the results.
A data-rich QR code can contain the information, not just a URL to take you to the information. If you can decode it in the phone, you can view the information on the phone, no data plan needed. If it' contains a link, you now have a copy of that link to take with you to check out later.
They could have left one of the toggle switches out and included some sort of a dead man switch. Foot or hand operated from a train perhaps.
I used to operate light rail vehicles. If you let go of the switch the the train went into maximum braking. I remember it was abrupt, can't remember if it automatically dumped the sand in front of the steel wheels or you had to do that yourself.
It looked like it lasted maybe 3 seconds in the air, no "deploying of X-wings" going to happen that way. What I was surprised about is that the rocket motors seemed to die just about the time the ship did. For a solid fuel motor I'd have expected them to burn until they were consumed. If they only had 3-4 second burn times that ship didn't look like it was in for a flight much longer than it did. The only difference might be that it landed in pieces rather than landing whole and breaking up on impact.
Yep, BS No other comments seemed to mention it, but the INQ article was referencing a Newsday article: http://www.newsday.com/business/ny-bzappl0908,0,2929341.story?coll=ny_home_rail_headlines Most of the way down the original article says : The Levys brought their phones with them for voice calls. It also says they thought the data networks in Europe were incompatible with the iPhone. Oops. Too bad they didn't know that the whole reason for using GSM is that it works more places than any other mobile phone type.
This sure implies that they planned to make calls, did they? If so, the phone was sure as hell not "off".
- If the phones were really off not asleep, there would have been no calls, no data. - If the phones were in standy and getting email, it makes a sound ( though an insanely short wimpy sound ) - They must have turned on international roaming before leaving, otherwise their phones couldn't have been used for voice calls.
It would be handy if the phones had a "voice, no data" mode, but since it doesn't, claiming stupidity shouldn't get you out of the bill. I'm not going to get too sympathetic over a family who ran out to buy matching iPhones just before their Mediterranean cruise.
A Mathematician Reads the Newspaper, among other books by John Allen Paulos, is excellent. In it he provides great examples where real stories seem to say one thing, but due to dodgy or obfuscated math actually mean something completely different. He points out that only by doing the math yourself are you able to know the real truth behind the real world news..
His website http://www.math.temple.edu/~paulos/ has some useful links. His stories come across much better than contrived word problems intended to show students why they might need to use math.
I'd need a good reason to upgrade from Eudora 6 that I'm using now. I've been using it since 1997 or so and have always been very happy. I don't use the IE rendering engine so it's clean, simple and just plain works. My filters have evolved over the last decade and work well. The small tidy files the mail is stored in a much more manageable than the humongous PST files Outlook uses so even my work machine has 8 years of email easily searchable.
I used a plugin for Google Desktop briefly to index the old messages, but searching was no easier that the built-in search so I just stopped using it.
Eudora is the one I app I have that over the years when I heard there was an upgrade my first thought was "why?" rather than "Great, I've been needing an upgrade".
I also use Gmail, having selected mail from my server go to both my Eudora POP account and my Gmail account. That gives me remote access and another backup If I have some funky formatted email that I don't just toss out, I view it in GMail via Opera where I'm well insulated from malicious attachments.
It would have been interesting if they'd ruled it was illegal. Vote swapping in Washington is done every day of the week, you vote for my bill, I'll vote for yours. While this is a slightly different type of voting, it usually has much more stringent requirements, i.e. no absentee voting.
This mechanism of reaching a compromise by agreement on how someone will vote on various issues is pretty deeply ingrained in U.S. politics, so it would be odd indeed to restrict it's use to elected officials only.
The basic mechanism for reflecting different colors is the same as used in "Zubbles", the yet to be released colored bubbles. The stucture dictates which color is reflected. Popular Science did a long article on the guy who went with this approach when trying to create colored bubbles for kids that didn't stain when popped:
Google provides views of the Earth, Moon and Mars, why not stars? If the information was made available for them to deliver to their users, they might be interested.
