It sounds like a nice solution at first, but you have to rely on the AP or Cell tower to have a unique IP. That will not be the case, as AP (until IPv6 if fully accepted and implemented) usually act as NAT router too and have a local network adress. Can you locate 192.168.1.1 for me please?
The article mentions mac numbers or celltower ID's that have to be linked to a location. Maybe you could resolve those locations with a DNS-like system, but I am sure there are more eficient ways to do that. A complicating factor is that the devices cannot rely on continuus net acces, so the lookups need to be queued until acces is available. And since they aim for handheld devices, you can assume the storagespace is restricted, making all the other fields that come with DNS not only useless but unwanted too. I can see you recently had a DNS-hammer in your hands, but this does not look like a IP-lookup nail, sorry.
Raid 5 allows you to keep 1 or more parity checksums of the volume. In principle you could use partitions on the same disk if you cannot afford a multi disk setup.
In a very short summary: RIAA: this woman shared our files on p2p MOM: no I did not, it was somebody else, maybe one of my children. MOM: yes it was Brittany, not me. RIAA: Ok, get the Dumb cow off the list MOM: No, I want my legal costs paid. Judge: nope, you should have turned in your kid sooner, so no money for you. But RIAA wants you off the list, so there you go, it has been decided.
Right, but that has very little to do with the overhead monorail. If you'd equip trams with rubber of teflon wheels you'd have a very quiet tram, that would need much more energy to run.
Aesthetically pleasing -- Since they are usually on raised structures
Big bag of bovine manure. Yes you can add it with very little surface footprint, but the towers supporting the rail are by no means invisible. I've seen the monorail in Sydney, and it is butt ugly with support columns every 10 metres or so. In non urban aera's a monrail is still very visible 5 metres above ground level.
Safer
That might be true. If it is 5 metres up in the air it is much harder to hit than a tram or train.
Less expensive in the long run
Less expensive then what? A bed of gravel and some steel rails on it does not cost very much either, and you can easily repair, replace or realign the rails at ground level. compare that to an overhead rail with pillars that cannot move/settle one inch. You will be needing thousands of those, and any movement in them will jolt the carriage when it passes.
There is a big difference between seeing a movie at the cinema and seeing it at the couch at home. You'd never invite a girl for your first date, to your livingroom. As an extra incentive you could give a discount if you have a ticket for that movie. But even so, some people do not like to go to the cinema, and would prefer it to stay at home and masturbate to the sight of Natalie Portman. You cannot do that in theatres, you know?
Ah should have read the article before posting...:
"I want them to sell 'Bubble' DVDs in the theatre lobby," Soderbergh says, smiling.
Maybe they will only sell the DVD if you have a ticket for it, otherwise you could be buying the whole lineup the cinema is running, and not return to spend more money.
Band routinely sell merchandise and CD's after concerts. You've seen the band and as a souvenir you can buy the album for usually less than retail prices.
For films something similar could be done: You have seen the movie, and you were -no doubt- very impressed. A very good mindset for the merchant that is offering the DVD right at the exit(at a less then retail price). Instead of complaining, theatre owners should grasp this golden opportunity.
few meters if you do not power the card yourself. As a previous poster already stated, the card needs to be powered remotely for it to work. That is done with a pretty big low frequency field IIRC. The reader that is sending this field also has to detect the response through his own noise, that is why you need to be pretty close before it works. If you do not have to energise the chip, you can just listen from farther away and you will be able to 'hear' what the card says.
There was this website on/. a while (can't be bothered to look it up now) where the author had built his own reader, that could record the emissions from rfid cards to open doors etc. and emit these signals to the real reader. He only had to stand nearby and push the record button at the right time to copy a card. A big coil, a pic and some other common components was all it took, he was very suprised about the lack of real security in them.
For creditcards i sure hope they found a way to do two way communication so you can do a proper challenge-response authentication. But that is still very insecure as it does not combine something I know with something I have. I guess merchants still have to pay a share of the transaction to cover for all the disputed charges.
How do you conclude that the implementation is poor? The implementation is the stuff the various distro's put in. What the LSB is, is a spec and a testsuite. His rant is about parts of the testsuite, which appear to be written by less skilled people. I agree that that is a bad decision, the test should at least be written by someone skilled in the software to test, preferably the software developers themselves. But testcode is not the deliverable code, it may contain bugs, just like any other piece of software. Where Mr Ulrich has a point too, is that there appaers to be no process in place to adequately fix the bugs in the testsuite, and what is being done with those fixes.
But Mr Ulrich proposes to throw away the baby with the bathwater. The generally accepted idea behind the LSB (one common architecture for commercial ISV's) is still sound even though the organisation and processes are a bit shaky.
Now we can't get the entire subatomic amounts Einstein was talking about but we can have the best chemical reaction amounts if we make a system that extracts the energy more effeciently from this reaction.
That sentence alone blew my kook alert fuses. As for efficiency: if Romancer(s car) is doing the driving, the efficiency drops form his alledged 30% to 0% as he has no idea whatsoever what he is talking about or where he is going.
Yes they try to avoid the word fork, probably for the connotations it has ('forks ar *bad*'). But there is nothing wrong with a fork an-sich. The size of the Debian project is what made it great(lots of packages, lots of testing, lots of development), but the size of Debian also makes it hard for commercial enities to cooperate with them directly.
Usually forks are considered 'bad' because of the duplication of effort. This fork is good because it prevents the structure of the Debian organisation to slow the efforts of the DDDMs.
Do not delude yourself with this 'law': you still have an awfully big envelope that you need to keep hot. It only becomes relatively easier if you scale it up, but not in absolute sense: A bigger balloon needs a bigger in-flight boiler.
Thanks to the very generous move from slashdot to/. the spoof site, it is not clear why others are critisising DCC. the spoof site at http://www.dccalliance.biz.nyud.net:8090/faq.html is pretty slow too, here is my analysis (and a copy of their 'faq':
What is the DCC Alliance?
The DCC Alliance is a collection of invdividuals with a link to Debian. It exists in order to counter the idea that the use of the Debian trademark is permissable if it's hidden inside an acronym.
So somebody is upset about basing the name of a separate organisation on 'Debian' and abbreviate that to a 'D'. Well wanker, I tell you something: you cannot trademark a single letter, or we'd only have about 36 possible companies.
What Does "DCC" stand for?
"DCC" is an abbreviation for "Debian common core Cheerleaders and Critics". Since "Debian Common Core" is a trademark of the DCC Alliance, only the abbreviated form is used in referring to the DCC Alliance.
(this seems a rip-off from the 'real' DCC faq entry. see above, no trademarks on single letters.
Will the DCC "fork" Debian?
Yes, the Debian Common Core alliance will fork Debian. As an example, the Debian kernel will be modified. Maintaining a branch of a package that is not identical to the upstream one is a de-facto fork.
Aha, a somewhat real-ish bone to pick. Except that creating a patched kernel is not such a big deal. You can find several in testing, does that mean that testing has been forked with every new kernel release? As long as the new kernel is interoperable with the one it replaces you can hardly call that forking.
is DCC necesary? Debian has grown into a big organisation, and thus also has it's share of people with 'uncommon personalities'. It is all a volunteer effort (and thus?) some people in debian react a little allergic to commerce baseed on Debian, even though the licence allows it. Commercial Debian-based distro's have a vested interest in Debian, so they seek some influence. It can be vey hard to have to argue with every maintainer whose package they have altered to get him to accept the changes(There are 1000's of developers and and at least ten times more packages in Debian). Even with proper conflict resolution it quickly becomes a nightmare, so a lot of distro makers don't feed their changes upstream/to Debian at all.
That is a problem and something that a separate repository can solve. Yes that is in effect a fork, in the same sense that Ubuntu or Knoppix is a fork (not for the silly reason above). If the Debian derived distromakers have their own repository where they can work together changing Debian to their common goals without getting bogged down in Debian rules/games, then that is just great, IMHO.
It is great for the Debian-derived-distro-makers(DDDM?), as it allows them to cooperate and improve Debian while they are at it. It is great because it avoids conflict and bottlenecks. Commercials distro's (can) have a different interest than induvidual Debain developers. With this construction no single Debain developer can obstruct a DDDM. It is great because It will concentrate all enhancements made by DDDM's into one place, so the Debian developers don't need to track all different DDDMs for changes to their packages. And most of all, it will concentrate efforts into coding and cooperating, and that is good for all.
Or you might try to develop a way to predict the succesfullnes of your project with a lot less money. The fact that you spend it (or burn through it as you put it) does not mean that it is the only way to do a feasability study. If you have money you always need more, if you have not you devise other ways to acheive your goals.
For when the revolution comes: you have approximately number (13/17)*10^6.5 (you openly admid to wearing a suit and work for an evil company).
Steam airships also need to keep the inner envelope at 100 C. Even with a thick layer of insulation, you'd still have a very large surface area that is constantly losing heat. Doing it zeppeling style and flying more than 50 knots will not lessen that problem. Maybe you will be able to recapture the heat lost from your engines, but you will still need to generage a lot of heat to keep this baby flying. Next to that is the fact that althoug people have speculated about steam airships since the beginning of aviation, no manned steam balloon has ever flown yet.
Personally I have done one small experiment with a steam balloon (1m dia.), but that only flew for about a minute. I think a manned steam balloon is feasible, but only if you take very small steps to get there. first 'augment' a regular hot air balloon with an internal steam envelope, where the steam is kept hot by the regular burner. The steam airship comes a lot of iterations after that experiment, but it should be feasible. If it makes econonmic sense is a whole different matter altogether.
propane powered fridges have been around for a ver long time. The method is not very efficient (you are heating stuff to cool other stuff) but because there are no moving parts in the fridge, it just keeps on going.
The trick to make it run on solar would be developing a technique to concentrate, collect and store solar heat. Next you use that heat to drive your absorption fridge where you'd normally use a propane or kerosene flame. If you're willing to introduce an electric pump in the system you could pump the amonia-water mixture through some solar-trough collectors on the roof of your icehouse and cool the condenser with air in the shade of your collectors. Such a system will use 30-40% of the incoming solar energy to freeze ice, which is not much, a few sqare meters are comparable to a domestic electric freezer.
But such a method would not use any sexy tech, so has little inventive for an ambitious engineer that will solve all the third worlds problems in one fell swoop.
My debian system has a manual update every once in a while (usually after i get the Debian Weekly News(letter)) How should this auto update feature workt together with apt-get? it's nice if it can signal there is an update available, but usually I dont run firefox as root, which would be the only one that has permission to do the writes necesary.
There is a difference between a kernel and an OS, you know?
I don't know where you read me suggesting that it was simple or easy. the testing suite will probably exceed the the actual kernel in size twice over.
As for if someone has aready made a start:
Linux Testing Project.
maybe you can, if you are a robot. People tend to like this game for the sensation. That will make them place larger and larger bets to get the same adrenalin high. It will also destroy any critical thinking while they are getting hooked. Human feelings and playing with money don't mix well, if you intend to keep your money. You can delude yourself you don't have feelings, but even sociopaths have some.
It could and it should. There is litle reason why the kernel can't be accompagnied with a test suite(probably twice it's size). then when you have compiled your kernel (during a long lunch) you start the tests and come back next morning. Then you spend the rest of the day figuring out what the tests actually test, and what it means if a particular one fails.
You will probaly nee a emulator like bochs to emulate and manipulate the hardware part, but it should be doable.
apart from the rethoric and aversion against BabyBush, they have some point about the environmental aspects of big floodgates. The delta works in the netherlands have turned one sea-arm into a freshwater lake. The westerschelde floodgates were supposed to leave the water behind it free-flowing. It's realtively small obstruction to the flow of water and sand had drastic influence on the sandplates behind it.
Because the current is now less, the channels and gullies between the sandplates are too big. As a result the plases are losing sand to fill these big channels. on some places the maintainers have started to supply extra sand to valuable sandplates.
Once you start to do that, you are no longer maintaining a nature reserve but you have just become a garderener with a big & unusually wet garden.
But on the other hand, if you want to keep the current environment, you will have to accept the occasional flood. But with those levees around the rivers that was not happening much either.
I doubt that, as reuters is in the business of ditributing news, not making it. The half-arsed interview is way to much work compared to: hey it sounds credible, they did pay our fee, let's put it on the line"
I think it was FSF-Europe beating their drum. To gain some acceptance the need to be subject in several newsitems. This was just one of them. I hope I am wrong on this one.
