1) To say 'It will never work because nobody has done it before' is very shortsighted. I would guess you've never actually invented anything.
2) I see it as a great anti-terrorist tool. Look at what happened in Madrid this spring. A train car full of people, one big fat target waiting for a homicide bomber. With the PRT the target areas are reduced from the traditional subway or light rail system.
3) The befouling problem is the same on any subway system at off-prime hours. Just make the care hoseable.
We've adopted the practice of entering into a contract with our sitter for 1 years worth of babysitting, 1 night a week. We pay her upfront so she has enough cash in hand to buy something decent, like a powerbook.
She's happy with the lump sum payment, and we get a for-sure babysitter for 1 year.
The RFID tag reading capability provided by the phone will not read the RFID tags that WalMart is requiring for it's top suppliers next year.
The Walmart tags are EPC class 1v2 compliant tags that operate in the 915mhz range. The Nokia phone reads ISO-14443A tags that operate in the 13.56mhz range. The two technologies are very very different.
The EPC tags are relatively inexpensive (and getting cheaper all the time). They have about 128 bits of internal nvram and can be read from about 1-3 meters.
The ISO-14443A tags are expensive. They've got large amounts (multiple KB) of internal NVRAM, some have embedded operating systems and file systems for the NVRAM. You won't see companies using 14443 tags to tag merchandise anytime soon.
Another problem with the 14443 tags is that it is based on a fuzzy ISO standard. The cross vendor compatibility between compliant 14443 tags and compliant 14443 readers is not good at all. For instance, a Philips 14443 reader may not be able to correctly read a STMicro 14443 chip, even though they both are 14443 compliant. Basically, ISO makes vague standards so that many companies can claim compliance, but none have to compete with in an open marketplace.
I think the Nokia phone will be useful for closed loop RFID applications (one where the tag is not required to interoperate across multiple companies).
A couple of months ago I was shopping for a new hosting facility for some sites I run. (My florida room was running out of space). I visited RackSpace and got 'chatted-up' by this feature. I was a little shocked at first, thinking this was a automatid response system or something. So I misspelled some words and used bad grammar and the person on the other end responded with real answers to my questions. The conversation did go to the next level with a voice-to-voice phone call. I ended up doing business with Rackspaces' little sister company, serverbeach and am pleased with the price and the service.
Active RFID tags are much too expense to place on everyday consumer products. Active tags cost multiple dollers per tag. And, they have some of the same RF limitations as passive tags, one would just need slightly thicker foil or a little more liquid to muffle the signal.
After working for several months with the new EPC compliant tags (what WalMart has mandated) I can, with a great level of assurance, say that one does not need a chip to prevent reading of the chips, that is way overkill, and probably not really reliable.
There are a couple ways to easily defeat the chips: 1) put the product inside of a foil lined bag. Doesn't even have to be heavy foil, any slightly metalic foil will block the RF signal to the point that the tag cannot be read. 2) Hold the product close to your body. The water in your body absorbs the RF signal, silencing the backscatter RF signal. 3) Put two standard RFID chips close together and the antennas will 'shadow' each other, blocking the signal from both.
From my experience it is harder to read the tags than it is to not read the tags. (the fact that you can read a tag is almost a miracle in itself) To build an entire chip to defeat an RFID chip is just stupid.
RSA is just looking for something else to patent, like they did the RSA algorithm.
I think the idea of a World Space agency is a first-class bad idea. The only thing that is getting the U.S. interested in space again is competing with the Chinese. If we had a WSA then there would be no competition and we would end up with a big useless space station in low earth orbit with a slow leak.....oh we have that....basically because the U.S. had no incentive to be bold and reach for some distant goal, just to beat somebody to some cold dead rock.
One wouldn't need to copy the LDAP data into a file system. Instead provide a view into the LDAP directory via filesystem calls. In otherwords, the filesystem driver would translate calls to it into LDAP calls to the LDAP repository, whereever it may be. The only persistent data that would need to be stored for the file system would be the how to connect to the LDAP server farm.
In regards to your second question. The standard getxxbyxx() calls are useful for returning username/uid/gid etc. But if the application wants to know something like 'What is the mailstop' of this user? There is no standard call, one must revert to LDAP API calls. So, your statement is correct in regards to system level information, but those services are inadequate for almost all application level user metadata queries.
It seems that the author presumed that the only use of LDAP is to provide passwords for user authentication. While that is a common use of LDAP it is not the only use.
It would seem that having a file system that is LDAP aware could be extremely useful. Imagine if your LDAP tree were reflected as a tree in your file system. You wouldn't need to embed LDAP calls in your application, it would just be data in your file system. So looking up an attribute for the current user, or a user, would be as simple as reading a file that holds the value of the attribute.

I worked at Philips Semiconductors up until about 9 months ago and they had a very strick policy: No GPL development, none, nada, nothing. The semi division was very afraid of having their intellectual property given away.
Seems interesting that the CE group would turn around and product a Linux based device, especially since Philips has been so cozy with MS in the past. I wonder if they are going to release their optimizations back to the world like they are supposed to, or if they are going to hord them.
The ReplayTV OS is a modified version of VxWorks from WinRiver.
One shouldn't immediately assume that there are only 2 operating systems in the world. There are a slew more than that, especially in the embedded device arena.
Of course it's a way for them to make more money. That's what businesses do. What's wrong with making money if your providing a product or service that people willingly pay for.
I've been running a site on 4.0 since last December. The only issue that I've run across is occasional index corruption with a fulltext index. Other than that, I've enjoyed the new features.
I've burned about 1000 CDRs on my computer at home, not a single one in violation of any copyright.
I don't see how paying a royalty tax per CD blank could be justified since many CDRs are used for completely legitimate purposes. I personally, would complain bitterly about having to pay a tax on 1000 CDRs when I hold the copyright to the content.
P.S. It's not a 1000 copies of the same content, it's 1000 unique pieces of content. I'm not that stupid.
No amount of nice furniture at work can suffice for sucky management and purposeless tasks.
Give me a job where I feel like I can make a difference, am contributing to the company, and am recognized for that contribution and I'll stand-up to work.
I had one such chair when I worked at a failing dot-com (now that I work at a failing semiconductor company I have a normal chair). My biggest complaint was that the chair provided no noise cancellation features. The wonderful mesh fabric does nothing to stop the noise of a juicy after-lunch fart.

The major flaw I have with the author's reasoning in this article is that he does not give God any room to be God. This is a problem that many people, both non-Christian and Christian, stumble over.
It is natural for us to see God as being like us and being constrained by the same things that constrain us (time, space, complexity, etc.) When we see God as unfettered by any constraint then the fact that He used common design patterns (Yep, God invented OO)should not surprise or trouble us.
You may call this a cop-out or a rationalization of an irrational belief. But, I see it as much more rational than believing that something as complex as a fruit fly or a human being happened via chance.
There's a little problem (actually more than one little problem) with your scheme. 1) To burn a disk in the amount of time a consumer wishes to wait would require a very very expensive DVD mastering system. I don't think many consumers would hang around for the 30 minutes to an hour it would take to copy a DVD. 2) Unless you charge the customer who has a copy of a DVD for the length of time they have the DVD (i.e., 1day=$2, 2days=$3, 3days=$4 etc.) there would be no incentive for them to ever bring it back. You would be basically selling DVDs at a very low price. Jackalope
A couple comments on your two biggest problems. 1) You still don't own the content. The studios only grant a license to view the content in the privacy of your home. So, despite the appearance, the studios still on complete title to the content. 2) Blockbuster, and every other video store still in business, tracks which videos you rent or buy. Grocery stores track what you buy, Wal-mart tracks what you buy. These retailers probably know more about your spending habits than you do just because they put alot of effort in understanding why you do what you do. Oh, and as the person who ran the Divx computer system deep in the bowels of Circuit City (actually in the basement of 9954 Mayland Dr., Richmond, VA 23233) I can say that the players credit card information was never sent to the player. But it did report Divx movie plays, and we never got around to doing anything with the data except for trying to bill credit cards. Jackalope
Don't we in the U.S.A. have a right to not be monitored (searched/seized) by our government? Isn't that the case unless they have probable cause to believe that we've broken a specific law. So, unless entry onto a highway makes it probable cause that we're speeding then they would have no legal footing on which to monitor our actions.
If they shutdown amazon.com's index.html for a couple of hours it might actually save Amazon some money. Seems like if they are doing business they are loosing money...so stop them from doing business and they might make money.
