"who exactly would be the target market? I can't imagine the average home owner paying a premium for this."
The TiO2 not only removes pollutants from the air, but it removes things like bird droppings and "gunk" from the roof (by the same photocatalyzed oxidization) - thus keeping your roof cleaner.
It was 3x13.8V (42V give or take), and the intent was to make doing things like integrated starter/alternator (wherein the starter motor is also the alternator, is permanently engaged to the engine, and can act as a "mild hybrid" assist to the engine).
It failed because: 1) They found that the "mild hybrid" idea didn't work worth a hoot - not enough benefit to offset the cost. 2) The established infrastructure of 12VDC for cars meant you'd HAVE to have a downconverter to supply 12VDC (just as the Prius has such a converter to take the 300VDC traction battery down to 12VDC for accessories). 3) The jump to designs like the Prius and other hybrid designs.
Yes, if your goal is to heat an element within the plug to light a cigar(ette). Oh, you actually wanted the watts to LEAVE the socket as electrical energy, not heat? Sorry, 16A @12V is dreaming - that's real world experience, not specmanship dreaming.
"...but that is something I have never seen. [...] I usually drive an old Chrysler Voyager."
And that is likely why you've not seen it "underfused" - I've seen plenty of late model vehicles, and 8A was probably the LARGEST fuse I saw on the lighter socket.
Some cheats for players: 1 Stay away from the nuclear waste dump. 2 Don't shoot energy-absorbing being with a laser - just get them in a powered-down section and wait for them to run out of energy. 3 Neutron reaction drives won't make you a lot of friends.
"Beyond that, there usually isn't much "extra" power available for non-factory devices."
That would depend upon the make of the vehicle and what alternator is installed. My car has a 120A alternator standard with an optional 200A alternator.
Of course, being a Panther platform, they expect that you just might add some extra lights, radios, and other things to the car....
Modern (beefy) laptops want about 70W when running, about 100-120W when running and charging. Pulling more than about 80W from a 12V lighter socket won't happen - most lighter sockets now-a-days are about 8 amps, and because the lighter socket is such an atrocious interface you really get about 11V at that current if the engine is running, so you are looking at about 80-90W.
Even if you do as I have done and use manly power connectors (e.g. Anderson PowerPole) pulling more than 10A means seriously thick wire for any length.
That's why many modern laptop power supplies run 18V or so - that extra 50% voltage means 2/3 the current at the same load, and 4/9ths the losses in the wire (for a given thickness of wire).
* dB are already logarithmic, so you don't need the log function. * A *real* engineer would use the signal to noise level rather than the signal level:
const int max_bars = 5;
const double sn_db_to_bars = static_cast(phy.Get_SN_ratio()*sn_db_to_bars);
return (bars>max_bars)?max_bars:bars;
}
I have to ask, at what percentage of the kid's life does this effect show up?
After all, if this only affects the kids' visual cortex development if they are spending 50% of their time on it, then I'd say, much like Olestra Potato chips causing "leakage" if you eat a bag of them, that you are going to be seeing other issues long before you see this.
Get the kids outside! Go Geocaching! Go to the zoo! Fly a kite - hell, how about you and your kid strap a camera to the kite and take some amazing pictures that he can take to show and tell?
How about the kid spending time AWAY from the plug-in-drug?
I cannot RTFA being it is dead, but my question about all of this "retina-level" stuff is: are they factoring that the eye uses dithering and jittering to increase the spatial resolution?
Last I'd heard, the current theory is that by using micro-saccades, the eye can increase the spatial resolution over what your would naively predict based upon the angular spacing of the cones.
There is a simple solution to this, once you realize some basic facts: 1) Who is the customer for the advertiser? Not the ISP, sure as hell not your the schmuck they feed the ad to - it is the company buying the ads. 2) What is the motivation for the ISP to do this? Money from the advertiser to support this. 3) What is the motivation of Juniper to do this? Money from the ISP to buy the gear, and money from the advertiser to buy the gear to process this.
So: Step 1: We need several sites that can detect that these headers are being added (hey Slashdot - how about showing a warning when you detect these headers?) Step 2: We geeks need to make a big stink whenever we detect an ISP adding these headers - and make sure the norms on the ISP are aware of how much of their privacy is being invaded. Step 3: We need to identify which companies are selling products using this technology, and do our best to see they get negative publicity for it.
Attack the money the ISP gets for this - make it cost the ISP, rather than profiting the ISP - and the ISPs won't deploy this technology.
Attack the money the companies buying the ads hope to make, by creating negative press and hitting their sales, and most of them won't pay for it.
Attack the money the advertisers make, by discouraging businesses from buying ads and by discouraging ISPs from selling the information, and the advertisers will (grudgingly) walk away from the idea.
I propose an alternative. All other countries should create a tradition of randomly setting explosive charges off in their stadiums whenever the South African team is there.
Since that is not a part of our culture, may I suggest an alternative that is a well established part of our (geek) culture: pointing laser pointers at things. Imagine if every geek in the audience pointed one of the WickedLaser 1W blue lasers at the opposing goalie....
It has come to our attention that you are in violation of our copyrights, by making unauthorized copies of our BluRay content using a device known as a Hippocampus. We are bringing suit against you for US$10,000,000.
"Also, if your 3G network is based on CDMA (WCDMA, HSPA, HSDPA) then signal-to-noise ratio is as important as raw signal strength."
Actually, this is true for ALL communications, bar none - S/N is what matters. You could have a signal that is barely 6 dB above what your receiver can detect and have a good S/N ratio, or have a signal that is so large it is driving the receiver into compression, thus distorting the signal and driving the S/N ratio down into the weeds. Shannon's Law.
However, reporting signal level is easy (look at the automatic gain control loop feedback term), reporting S/N is much harder, so most devices cheat and report signal.
No, you are not alone. Any form of remote access to a vehicle is an absolute deal-breaker for me - I don't want OnStar (am I the only one who finds their ads creepy? Especially the "stolen car" ad?), I don't want remote diagnostics, and I WILL NOT buy a car with them. They can get all the diagnostics information they need from the OBD-II connector in the car, which requires them to be IN the car, and presumably with my permission.
And I *won't* tolerate having anybody GPS track my car "for road taxation" purposes, either: you can do the same thing more simply, more effectively, and with more privacy by just raising the fuel taxes.
We need to assign responsibility to those who can do something about it.
Every day, my firewall emails me a list of port scans against it, sorted by IP address. Most days that list is just under 100 different IP addresses scanning me, some days it is in the thousands of IP addresses - from all over the Internet (i.e. not just local addresses). This is on a residential DSL connection that offers no services to the world, isn't linked to by any web sites, and does not respond to any unsolicited traffic.
It seems reasonable to assume that most if not all of those IP addresses represent infected machines. Were there some way to get them shut down, imagine how much cleaner the Internet would be. However, there IS no way to do so: the ISPs hosting those machines don't provide any meaningful or automated way to report them, there is no way to contact the owner of those machines, so they just keep on spewing and infecting the rest of the system.
Nor will ISPs ever provide an automated way of reporting such machines as things stand now: a reporting mechanism is an internalized cost, and there is no reason for an ISP to internalize that cost when they can externalize it to the rest of the Internet.
This is one of those rare cases where "there ought to be a law" is a reasonable response: were ISPs required by law to investigate abuse reports and disconnect infected clients until those clients are cleaned up, the number of infected machines on the Internet would be reduced, the profit margins of the bot-herders and spammers wiped out, and the system would clean itself up. However, such a law would be fought most vigorously by all ISPs precisely because it would be internalizing a currently externalized cost, and it would be worth vastly more to ISPs to prevent such a law than the cost of lobbying against it.
(NB: "repeatedly submitting false abuse reports" is itself abuse, and should also result in the source of the false reports being shut down).
It's about control - you can control a forum, you cannot control a newsgroup.
This has good aspects: with control you can kill spam, bounce griefers and trolls, and generally promote a more thoughtful discussion.
This has bad aspects: with control you can kill dissent, bounce critics and whistleblowers, and generally promote a more "corporate" discussion.
In the modern business environment, business managers are conditioned to seek control - it's no different Microsoft or Apple or IBM or RedHat, it's just a matter of degree.
Reconnaissance can go horribly wrong

The next chapter is "Reconnaissance" and this is where the hacker background of the authors finally shows up. They show, with examples, how to find the name and email address of recruiters and HR people at practically any company. The theory being, if you can directly contact the HR people at a company, your resume will not be lost in the 1000 other resumes that people send in.
Allow me to present the other side of the coin: I am not HR, never been HR - while I review resumes *after* HR has filtered them (to do the actual technical evaluation of "is this person bullshitting or do they actually know what they claim to") I do NOT do front-line filtering of resumes, nor is it appropriate to send me a resume. Yet, I have had several "recruiters" send me their marks - err, "clients" - resumes. And do you know what happens then? Both the recruiter AND the "client" get blacklisted by our HR department when I forward the message onward.
In short: if your "reconnaissance" isn't spot-on, you can hurt yourself more than you help.
The funny thing I've noticed is, the cheap motels (Motel 6, Super 8, Econolodge) pretty much all offer decent WiFi for no additional charge - even the little mom-and-pop motels are offering free WiFi.
On the other hand, the big boys - the Sheraton's, the Hiltons, etc. - that I've stayed in all either a) have no WiFi at all, just wired Ethernet into a DSL-like system running on POTS cat-3 wiring (and often only for pay) or b) have WiFi but charge you for it.
It seems to me the places where you are staying on Other People's Money (places that cater to business travelers who expense the trip) are gouging on WiFi, the places where you are staying on your own dime all recognize WiFi as a competitive point.
I know that when I am traveling on my own money - you don't have free WiFi, I don't stay with you if I have a choice, and I almost ALWAYS have a choice.
