Netflix released data to get a better recommendation system.
Yes, but netflix has a very good system already. Now Tivo, Blockbuster, inteliflix, Dish, etc have a well researched starting point to catch up. and they have more data than the researchers, etc thanks to Netflix data combined with in house.
Granted the winning solution looks way to computational, and data intensive to run on a Tivo box at real time. I guess those units with the regular phone connection could have it processed off-line and receive it later.
What Netflix did gain was publicity, now everyone knows they have a kick ass system of recommending movies. I know I started giving more movie feedback because of the press.
they care, and say they think it's terrible, but they keep on buying the music.
brand recognition and impression is definitely a difficult thing to measure, even more difficult to put a $ value on. Because I have a strong dis-trust of Microsoft, Sony It hasn't stopped me from purchasing their products, but it has definitely slowed down my purchases. (personal purchases may be 0, but I still will buy what makes sense for the company...) And it can make the consumers, law makers, and judges more willing to think twice about the power these company's are allowed to swing.
find that the Prius actually out-accelerates most cars on the road.
most 4 cylinder FWD automatics anyway.
Just looking at Toyota's cars, The quoted Pries 9.6s 0-60 time (forget the real world number of 10.4sec) is faster than about 1/4 of Toyota's cars, it beats the camry, and 4 cylinder celicas times of 10-14 seconds, and the Tercels 11s time. of course lags significantly behind the Subra models (4-7s), and only a little slower than the 8sec Camry V6's.
The 258 ft/lb 0-400rpm range of the electric motor is good (not anywhere near my diesel) but it doesn't maintain that at higher rpm.
But the fact is that, currently, hybrids do exactly that
actually, the crash passing hybrids, seam to use alott more composite materials to bring the weight down in other areas to keep their performance equal. the numbers I have seen for cars offered in most modes, the hybrid part keeps the performance equal for the weight.
As you say, they will get better, as we figure out how to safely get higher voltages, through butter power components, and better gearing reductions to reduce winding sizes, etc.
I have to agree with you analysis, except which occurred first? Was the phone smashed in the fall causing the burning battery, or did a burning battery cause the fall.
It would be very easy to fall 50 feet onto the cell phone, but unless the cell phone was trapped against his body by something stronger than his ribs, or flew 50 feet away, even if it was hydrogen that went nuclear in their, it would have had to throw pieces of the phone a long ways to balance this force needed.
exactly why titles aren't needed. You let the AI algorithm make the basket. When you have processed a big enough data set a good AI algorithm will have matched the pattern already. IE if 99% of the people who hate tt0365748 also hated tt0425112 then the algorithm will have already picked that out of the sample data. It would even more so avoid suggestions like recommending identical title movies, that have nothing in common.
You would only need the aggregate data, if you were picking which movies to create, or how to sell the movie to the person. IE a genetic algorithm may pinpoint the reason, for the correlation between the two movies. But only after the pattern match already picked out the correlation. Now it might make allow you tell the person person who liked "Bridges of Madison county", and "Field of Dreams" that "Twister was also filmed in Iowa" when you recommend it, but that wasn't allowed in this competition.
just because someone choose to go public with liking "The Rise of Theodore Roosevelt" doesn't mean they should know that the company will take some seemingly private data linking you to really likeing "brokeback mmoutain", and the series "The L word" and publicize it later. and that the combination of your post, and the combination now violates netflix's privacy policy (in spirit) IE they say they will only disclose "on an anonymous basis" anything but your reviews. We know from the AOL disclosure, linking data to a number that represents you. Doesn't qualify as anonymous anymore.
one step too far to say that you can determine anything but movie preferences out of a movie rating list.
also your taking a aggregate of the household. So a household (will call them Chen'ys) had a gay kid, and the devil living in the same house with a Saint... good luck figuring out when the gay kid updates the queue, and when the Wife, or the Devil is at the keyboard.
It launches and recovers automatically and has an automatic control
looks like to me, their 20' wide sail launches/recovers automatically, except the first ~20'. (actually looks like you would need 1/2 the width + a couple feet)
So a football field sized sail would self launch, after launched manually/recovered from a 50m tower??? Granted big cargo ships are nearly that high out of the water.
Makes me wonder if they don't plan to launch a few of these 20' models that would then launch the big one. now their tracking and control better be darn good to bring it back down controllably in anything but a light breeze. I would hate to be the captain that has to set idle in high seas waiting for the wind to die down, so you could pull this in at sea, (I am sure you aren't allowed to catch Jet's leaving the SanDiego airport (for example))
Toshiba isn't providing XP drivers for the Laptop I got either. Interesting though, I found a nearly identical gateway system with XP drivers, that I am now using.
I couldn't recommend more skipping the Toshiba Vista Satallite, I bought 2 different version the same weekend. Vista crashed, and gave many errors within seconds of first power-up, all I was trying to do was get encrypted wireless working. Which wasn't possible, because without internet access iexplorer crashed immediatly, and all help launched iexplorer. With wired connection, and many updates, vista worked good enough to copy all the XP drivers to the hard-disk with only a occasional lockup (it would generaly recover, after 5 minutes without a reboot.) This was partially caused by Toshiba's zero configuration wireless tool. once I was able to un-install that, the system would work under Vista, now I still haven't got it where I could watch divx movies over wireless, which works flawlessly on XP, same machine.
Anybody who says Vista isn't Windows ME, didn't get the same drivers I got with Vista. Now this is squarely Toshiba's fault, anybody shipping a laptop that has applications crashing (with BSOD's) within seconds until connected to the Internet can't be solely blamed on MS. Then again the Windows ME PC I had never gave me a fault, is now XP.
So if yuu don't value the handcuffs to the Amazon Store that why would you bother buying one just to hack it?
I wasn't serious enough to look at it twice, but it says you can just email it your documents, it did just say word, and various music, picture formats. Also unlimited free lifetime access to wikipedia. So I am not sure what needs hacked either, just waiting to hear what formats work, and how usable the email capability's/formats are. If it can be turned into a $400 for a lifetime subscription to nation wide wireless email access (even if I have to run scripts on my home dsl to parse everything into a word document, and forward it, and recieve only). Then it'll be my must have.
The BOM on the thing would run you less than $200
similar to the Iphone, this has one revolutionary part, that is not available anywhere else (to my knowledge) that is the display. Like the Iphone, this revolutionary aspect is most certainly over-hyped, but I know I will be much more interested in shoulder surfing this than I was the Iphone.
I think the next step is where a more educated users would separate. IE, when your browser comes back with: "zdnet.com whats to update your browsers ssl layer with a untrusted application from zdnet.ch"
IE you would hit cancel, close the browser. Open new session, log into myvisa.provider.com, report fraudulent activity.
I guess it depends on what your delivering, I assume he doesn't want to send a registration key for his software straight to a botnet owner. But he still wanted to sell this application to a customer with a ow3nd b0x.
a) useful
by adding enough layers of security through obscurity, he will be able to send a functional DRM'd file, that wont be of any use to the botnet owner. But will work for this "bad" customer, on this one install. But still send a non DRM more satisfying version to "good" customers.
d) ethical
sure, if your definition of ethical is to "screw them before they screw me."
you are and idiot if you are not backing things up.
you are an idiot, if you spend more time backing up your files than it took to get/replace them.
Actually in a purely economic sense,
TimeToBackup*chance of failure ~= time to recover without THIS backup. of course you must add in the economics, but backups generally cost significantly less in actuall $ than in time.
this is why smaller organizations only backup securely (off site...) no more than monthly... If I only get one failure every 5 years, and it takes me 1/8 day to backup, if I backup monthly I will spend ~ 2 weeks time backing up before a failure. So if it would cost the company no more than 2 man weeks labor, to recover from a typical 1 / 5 year failure, and will, on average, be 2 weeks after the last backup, then my backup schedule is sufficient.
People didn't want to leave 2000 to upgrade to XP, and as we all know that happened.
I think the difference was most company's still had 98, so they were supporting 2-3 different OS's.
So you replace your 95/98 desktop machines with XP, because thats what PC's come with. Then once you figured out XP and it became stable you could go to a single operating system for all your windows boxes, including servers.
Today, most companys are only running XP. So what does Vista offer, as long as a few PC venders still supply drivers for XP, you got a supply, and as long as MS allows the renewal of site licenses for XP...

You want to verify that the whole software stack is operating correctly before you can trust the result. Having the source-code is a pre-requisite to this exercise.
I disagree, it is certainly possible to prove to a reasonable certainty what a black box is doing. It may be easier, or more though to prove looking into the box. As you say, for all practicality no one is going to be able to confirm the entire software stack, by looking at the code for any proof. unless your running the final step on a basic stamp. But if you re-run the program multiple times with the same result, and you run multiple iterations of very similar problems that you know the results of, and they all agree, you can build a reasonable proof.
I never knew that New Guinea was in any way closed to tourism. What's all this about needing permission to visit?
I suspect, like the US, it is not closed to tourism. However if your not a US resident, you can't legally just Yacht up to a beach in Boston tie off, and walk into town to do some shopping.
So I think they were allowed to forgo a official visit and a Visa application fee...
What would you take back in time... stainless steel needles.
good news, it's just a boat ride to go back and forth in time.
My Aunt was island hooping around New Guinea in a yacht last year. They traded a few fishing hooks for a handful of pearls. She had been given permission to visit in return for transferring donations like clothes, and medicines on her boat to the islands.
So their are still places where shaped metal is still difficult to come by.
I don't know of any steganographic programs with plausible deniability that are out at this time.
you did state one of them, truecrypt supports dual encrypted file. True you mount that as a partition to view it... so if you always send across a truecrypt volume as a attachment...
so if you choose a file size bigger than the biggest file you'll ever want to send, and always send a true crypt volume of that size, with some of your financial information in one key, and your guilty stuff as a second key, and the rest would be random garbage.
now if the file sizes kept changing they would have a good idea your hiding more, and they may be very doubtful so you may want to send big files regardless the content. Also true crypt does support as many layers as you want to create. IE, you can create a volume inside a volume, inside a volume. So you could give them 2 keys deep, the proper path would have to create a bigger partition than the real content. So again you would likely have to hide your content in a file that is 4x or more bigger than the original content...
definitely always a compromise, as a data gatherer, and reporter, I have a choice. 1) small laptop, = small screen + smaller keyboard + really portable, travels well, isn't in the way while gathering data in the cab. - sucks for report writing. no way (for my vision) to have 2 applications open on same screen, to compare,etc. when I got 30 things graphed, no way to see all the differentiation 2) Large laptop = full size keyboad + large screen + great for reports - difficult to carry, setup, keep display private, and no room for a spare. (yes when they fly me to Chile for a week into a dust bowl with a bunch of equipment, with licensed software that is locked to hardware, and only over priced spanish language Laptop available localy, and equipment that produces $10000/hour that must be scheduled down a week in advance, their is no room for no backup.) 3) Tablet PC + good keyboad, good screen size. - expensive, still not a desktop size. fewer choices = missing ports/options of standard equipment. even looks expensive, gotta fight the theives away.
Works much better for me to have a couple small laptops, and setup a external screen/keyboard when at a desk.
Since I process lots of data, screen space is needed. Since that data is also collected onto a laptop first, even more so. So I have a KDE Desktop, running synergy 19" LCD (biggest that fits under the hutch) Next to this I have a separate file cabinet that has 21" CRT monitor, and a laptop stand (similar to http://www.apc.com/products/family/index.cfm?id=265) this pushes the laptop screen up to the same height as the top of the other monitors, and more importantly gets it closer to me, since the keyboard is vertical now.
with synergy (IE my desktop keyboard and mouse) now running the laptop, the Laptop keyboard/pad isn't needed. With synergy going over the network connection, their is nothing to plug-in, wifi picks up the keyboard/mouse for me (I usually plugin a network cable, and power because I get ~500MB files to transfer) I plug in the monitor to the laptop, and do the extended desktop when producing reports.
now I built my own laptop cradle. Because I test vehicles with metal dashes, I have a magnet that snaps to the dash of our vehicles, it also attaches it's self to my desk. I made swing down legs with the magnet attached, so it is a additional protective cage when in my bag, etc. and adds only 1/4" to the Laptop size.
but, if you and the employer agree to changes in the contract, that you do keep a notarized copy for yourself. Or if it is just a single page, 2 copies, both hand signed, so you have a hand signed copy in hand.
Doubtful someone in your company would be so underhanded and falsify the document, but it happened at my employer (not sure by who, and not to me.)
both parties photocopies? Notarized, or the copy doesn't exist (IMHO IANL). Notary is required to keep copies, and should be independent.
If their that dishonorable, photocopies are no good. A co-worker pulled his records, to find that they had photocopied his signature on a different sheet. Without a notary, a copy is no good, IANL. Didn't go to court, and he still had his copy. but their wasn't anything more convincing of his copy.
At a minimum if their are 2 signatures, get the copy before they sign/initial, so you have a "copy" with actual impressions of a ink pen. That would give you the edge over a photo copy.
