Can't virtual hosts be NATed or something and each domain given it's own private IP address?
No, but you can run about 60K (roughly) SSL hosts on one ip address by running each on a separate port. I would imagine this is not terribly efficient WRT server resources compared to non SSL vhosts. URLs would look like:
This google searches or hyperlinks fine but human beings don't type in URLs like that very well. Do human beings ever type in URLs anymore? Due to domain typosquatters I certainly do not.
"HTTPS" is more or less setting up a SSL link and running plain ole HTTP over that secure link.
No the SSL encryption layer is done before the HTTP layer does it's thing. So if you identify your vhost as part of the HTTP header, then you're not going to know your vhost name until after the SSL is already set up and working, classic chicken and egg problem.
HTTPS/SSL a good argument for going ipv6 where there is no particular shortage of ip space.
With regards to 2 D universe in the early universe, "Flatland" was from 1884. Err... 1884 is "early universe" to this 5 digit UID, you lower digit UIDs probably think of 1884 as your middle age.
Third, broadcasters's greed is their own worst enemy when it comes to signal quality.
Greed is also causing programming problems...
These subchannels are usually re-runs of crappy old TV/Movies, music videos, shopping channels, and other junk like you'd see on basic cable.
One station in a market puts up a "weather (sub)channel" that stations rolls in the dough. Obviously, all the stations must copy them and put up their own weather (sub)channel so as not to fall behind. None of them can pull their own weight against all that competition, so they all implode. Locally we are post bubble; my favorite weather subchannel is now continuous infomercials and laywer commercials with an intermittent weather border. Soon we'll have no weather (sub)channels in our local market, because like yogi says, no one goes there anymore because its too crowded. Kind of like the "news helicopter" cycle which has a wavelength of about a decade from the peak where all the stations have one to the trough where none have one.
I don't think "better for motion" matters. All that matters is conspicuous consumption (look at me, I can afford 1080i and you can't, ha ha!) and marketing numbers (1080i must be better than 720p because it has a higher number, right?). You must realize the average american TV in the CRT era was dusted less than once per year and never had its color / hue / saturation / brightness / contrast controls adjusted. The video equivalent of the audiophile is too small of a market to pay attention to. The only important part about HDTV is showing off to others that money was spent, and having larger numbers to brag about, picture quality is simply irrelevant.
Seriously though you have to decide if you're trying to make them learn, in which case tossing them in the deep end at arxiv is appropriate, or just filling time and trying to be cool, in which case its youtube video time.
It shows that phrase technically existed a decade ago, but in the last year or so its usage rate has gone exponential upward.
I had never heard that phrase until the last couple months, now it seems all/. stories involving cellphones must contain the phrase "feature phone" to refer to anything that is not iphone, android, blackberry, or the also-rans. Basically, its a cell phone with a touchscreen instead of a keyboard and its really expensive, thats all.
Kids could observe, but its probably a heck of a lot easier to use the lightcurve generator. Don't tell them about the different kinds of variable stars, let them discover it for themselves.
Ideally what Apple would do would be when you set up your device in iTunes, you can create a "gift card only" account on it that would only bill gift cards and wouldn't buy something without enough store credit. So kids could still download free apps and spend their gift cards on apps/DLC but without the fear of it charging their parent's credit card.
Grats, you've described the exact set up my son has for my old 3G ipod touch (the one with the incredible 45 minute battery life coincidentally right after IOS 4 upgrade). It was pretty trivial to set up.
Disadvantage is when you go to the store and see those giant racks of gift cards, he always wants to buy an itunes gift card. I suppose its healthier that fast food gift cards.
I have a hard time with any educational or technical material which claims to be appropriate for everyone from beginners to advanced. If you cover that much material, your book is either several thousand pages long or you are probably not truly serving at least one of the ends of the spectrum.
Or laser focused on one tiny little thing...
Next up on/., "Learning printf on GCC 4.1.1" in 432 pages
Current version of GCC at the time of writing of this review is 4.4.5 assuming you use Debian Stable. That does not make the book obsolete at all.
I think it would result in a shockingly fair society.
Your description of small town / village life is pretty accurate up till that point. Knowing everyone elses business doesn't make them any less spiteful, arrogant, tyrannical, whatever, it just means they're output is better at leveraging their influence given more input data. The vast majority of people don't find small village life to be ideal living conditions.
I don't think he means people would watch you in the bathroom,
Classic example of you are probably are better off not knowing. The only thing worse than my weirdo neighbor watching me take a dump would be knowing that he knows, that I know, that he knows,..... etc... , that I know, that he is watching me take a... or something recursive like that. And that's before the recursive impact of a 3rd party watching both of us, while we know the 3rd party is watching, stirs the pot. Recursive privacy violation is a concern that has not been previously discussed here on/.
Storing your credit card numbers when you use them via a magnetic swipe is actually illegal, see here for example. So, supermarkets actually cannot store your credit card information.
(rolls eyes) Oh spare me. Ram the card data thru MD5 or SHA1, it and store the hash. We were storing the hash not card data. Salting is complicated for reasons which will appear obvious later on. When a new unique appears in a customers transaction record, put that account in the scrutiny list, apparently they have a new credit card account. When someones hash shows up in someone elses account add them to the scrutiny list, either they got married or they're a really stupid thief.
The scrutiny list need not contain the hash of the card data, in fact it probably should not, nor even list why an account was added. In fact there is no need to explain why they appeared on the scrutiny list at all. There are other reasons why accounts appear on the list, such as bouncing a check. At the start of every business working day for the credit risk evaluation auditors or whatever the heck their job title was, if the scrutiny table contains less than X rows where X equals the number of auditors times how many accounts they should handle per day, add randomly selected accounts to the scrutiny table to bring the total up to X so the auditors can be kept sufficiently busy.
People with accounts on the list get treatment much like the initial application phase, but maybe a little more intensive, maybe a little more attention paid. Maybe rerun their credit report to see if their check cashing is still an acceptable risk. Examine that customer accounts recent purchasing history, are typical thief products being purchased? Maybe they got married so start sending them married people coupons (anniversary cards?). Frankly 99% of them got blindly stamped approved, it was a buck passing operation to push the blame for any fraud onto the auditors, whom were basically required to permit the fraud while taking heat for it. Not a terribly pleasant job, usually used as punishment.
The same thing is done with checking account data. Hash the account portion of the check number and store it, look for weird patterns.
This was all circa 1994 and I was closely although not directly involved. I suspect nothing has really changed since then other than what took exotic hardware and software is now done with commodity gear.
My son works for a bank. They gave him a test phone that he could swipe over appropriate card readers just like some credit cards. When people saw it they said "Where can I get a phone like that?" Definiately a market out there.
Tell them to get a stretchy silicone case for their phone and put their contactless credit card in the back between the case and the phone.
I did that for YEARS with an ipod and one of those RF door entry card keys. I was astounded at the number of people whom thought I had hacked the ipod or something. Obviously an ipod nano or shuffle would be a bit too small. Works well with an ipod touch. Probably would fit with an ipod classic or whatever they call it.
Obviously this doesn't work well at security theater installations that ban ipods just to be annoying (because good security is annoying, anything annoying must be good security, right?)
I can simply hold up my wallet with my credit card in it to pay for things.
I detect the presence of singular. How does it work when you've got 3 contactless CC (the "main" the "backup" and the "shared family") and a bank issued debit/credit and a RFID drivers license and a RFID library card and one RF "door key" card for work and another RF "door key" card for the daycare front door? My wife has a couple merchant cards (Target card, etc). Then there's the RFID passport which I normally do not carry and a possibly contactless debit card linked to the cash account at my brokerage which I usually do not carry.
How does it "know" to bill my CC that has 1% interest instead of overdrawing my checking account? My guess is, if a protocol is ever set up to handle this, it'll be to maximize bank fees and interest charges, not minimize.
The whole point of the contactless payment systems is you wave your phone over something and it's paid for.
I never understood the whole point of contactless payment, in that I'm already burning 30 minutes driving there, an hour walking around, at least ten minutes standing in line, perhaps ten hours of labor at work to pay for it, and thats all OK, but 2 seconds to pull out my wallet, WELLLLLL thats just an insurmountable obstacle, what do you expect me to climb mt Everest here, that's crazy talk, gimme a contactless system or I'll never shop here again?
The other mystery I never understood is I always have a backup plan. My visa card got stolen or declined or whatever (actually happened to me once in the 90s) thats no problemo I got a mastercard right here, and an american express too. And cash. And a check card. Furthermore I will not bore you with the details but I "need" to use certain cards at certain places because one gives the most cash back at the gas station, the other gives the most cash back at the convenience store, and the other is a "shared" card for shared family expenses such as food store. So a contactless system for me will have to hold multiple accounts and I'll have to F around with some manner of menu system to select which I want/need to use and hope I get it right each time. Of course it would be a hell of a lot faster and easier to pull out my wallet and whip out the correct card.
Finally I don't understand this whole "I don't want to carry a wallet only my cellphone" thing. First of all until they put drivers licenses on contactless it would be illegal for me to be outside of my house without my wallet for all practical concerns, because how would I get there other than driving without a license? Next, assuming you're somehow legally outside without ID, in some states (although not mine) if you're the wrong skin color and you have no ID, the cops will put you thru absolute hell up to and including attempts at deportation... or you could just carry your wallet. I could go to the bar without my wallet, thats fantastic, err uh, well actually I don't care, but I can't anyway because they'll want to card me, so I guess I'm bringing my wallet.
It does seem like a very expensive solution in search of a problem.
While I suppose it wouldn't mean all that much when it comes to day-to-day work on some level it would be nice to work somewhere "cool". A company with "mythical" server parks...
Been there, done that, strongly advise against it.
The sales guy whom was selling used cars last week (no kidding) walks the new client thru, and you have to grit your teeth the whole time as he points to the UPS and calls it "The Internet". The new client is of course completely non technical so he nods his head. Repeat every freaking day. One funny story is all the promotional pictures are of, I kid you not, male and female models. Some of you could have theoretically seen my chair and desk, but that model is not me. They have a rep of being stuck up but I found them tolerably nice in person.
The only good part was we got leftover food from all the promotional meetings. And there were a lot of them in the dotcom era. Lets just say I gained about 75 pounds while I worked there. That gives you some idea of the scale of the fine dining.
...no commercial value, minimal scientific value.... basically worthless for long term space exploration
There were plans to do all of that. Cut to save money of course.
now build a tanking platform with robotic spacecraft construction/assembly/food production/power generation/roid mining gear at lagrange points l1/l2 for staging earth/moon/mars/europa missions
Hmm. Lets see how that would play out. Well, we had to bail out a banker whom was a major campaign donor, so there goes the cash for the storage tanks. Add an expensive unwinnable permanent land war in Asia, so we had to cut the robot arm and food production bay to buy ammo. Social security is running out of cash so we'll cut the asteroid mining mission too.
Leaving us, yet again, with:
... they can sit there and stare out at the earth from the... portholes for six months at a shot...
Only 7 more marketing campaigns until we reach "hexadecimal B"-gees. Complete with "that 70s show" tv commercial tie-ins and a coupon for a free pair of levis bell bottoms and a village people DRMed ringtone download. I can't wait!
Why can't they just quote what their average download speed is?
Because then people will divide their 20 meg cap by their 20 meg marketing speed and assume they can only use their phone for one second, and "I'm not paying that much for 1 second of service". Even if the 20 meg speed is pure marketing and you'll actually achieve 9600 baud speeds under normal use.

Although theoretically you are correct that in a decade or so it will be a usable solution.
Can't virtual hosts be NATed or something and each domain given it's own private IP address?
No, but you can run about 60K (roughly) SSL hosts on one ip address by running each on a separate port. I would imagine this is not terribly efficient WRT server resources compared to non SSL vhosts. URLs would look like:
