I was saying to my sister that Apple's integration between the file system (HFS) and the command line wasn't all that good (eg. if you cp mv files with resource forks, the resource forks don't get brought across). I understand this is to be fixed in Tiger, but it's annoying that it isn't done in the current and third revision of OSX. She's talked to a number of people at Apple and their take on it is that it's a surprise to Apple that all the Unix geeks are actually taking to OSX. A pleasant surprise for them, but still a surprise.

Since you brought up Brin's Uplift Universe, probably the biggest bone of contention between the races of that universe was how many rights to give those uplifted creatures.

The primary job of a manager is to make sure communication happens. Communicating the needs that the company has to the people you're managing, communicating the problems that the people you're managing to the powers that be, and communicating the information among your employees they need to get the job done. You don't actually have to DO the commmunication, just make sure that it's happening and nothing's getting in the way of it...
Alas, every article i read on SOA uses big words and says basicly nothing. It seems to be another retelling of the client server model we've been working with for the last 15 years (not that there's anything wrong with that). Still it's being pushed as the silver bullet that will save us all when it might not be all that.
The connection between the ELF (and VLF for that matter) and weapons of mass destruction is that they're for use in support of nuclear missile submarines which are delivery platforms for true weapons of mass destruction. Whether it's good or not that the US has them, we shouldn't deny their destructive capability.
It's not that bad. You just have to realize that 12 year old girls (our target market, despite protestations otherwise) need internet access too. I understand it's pretty bad in customer service (as it is everywhere), operations can have odd and somewhat inflexible hours, but development (particularly server development, where i am) is pretty good. It's a Unix shop that cares ab't quality and scalability, what could be better?
From Bruce Schneier in Applied Cryptography:
Thermodynamic Limitations
One of the consequences of the second law of thermodynamics is that a certain amount of energy is necessary to represent information. To record a single bit by changing the state of a system requires an amount of energy no less than kT where T is the absolute temperature of the system and k is the Boltzman constant. (Stick with me; the physics lesson is almost over.)
Given that k = 1.38x10^-16 erg/Kelvin, and that the ambient temperature of the universe is 3.2K, an ideal computer running at 3.2K would consume 4.4x10^-16 ergs every time it set or cleared a bit. To run a computer any colder than the cosmic background radiation would require extra energy to run a heat pump.
Now, the annual energy output of our sun is about 1.21x10^41 ergs. This is enough to power about 2.7x10^56 single bit changes on our ideal computer; enough changes to put a 187-bit counter through all of its values. If we built a Dyson sphere around the sun and captured all of its energy for 32 years, without any loss, we could power a computer to count up to 2^192. Of course it wouldn't have the energy left over to perform any useful calculations with this counter.
But that's just one star, and a measly one at that. A typical supernova releases something like 10^51 ergs. (About a hundred times as much energy would be released in the form of neutrinos, but let them go for now.) If all of the energy could be channedel into a single orgy of computation, a 219-bit counter could be cycled through all of its states.
These numbers have nothing to do with the technology of the devices; they are the maxiumums that thermodynamics will allow. And they strongly imply that brute-force attacks against 256-bit keys will be infeasible until computers are built from something other than matter and occupy something other than space.
While i don't think this is the way to go about it, traffic problems could be alleviated by communication. For example, if someone knew you were going to let them in ahead of you, there wouldn't be this mess where both of you would slow down, then speed up, &c'. This seems like it would like to aid in this, but ends up being cutesey.
About 10 years ago, I had a problem where my Informix client wasn't seeing the server. The tech support drone asked me to check my/etc/hosts file. When i replied that the server wouldn't be in there because we were using DNS, he told me that Informix didn't support the use of DNS. Even 10 years ago, they supported it. Turned out to be a bug in their (then) UDP based server discovery.
I don't recall anything as heinous as the Windows Registry in VMS. Pathworks may have had something similar, but Pathworks was some hacky PC addon. Even the ACLs in VMS were different (and really, not quite as functional) from what's offered in NTFS.
