I thought 'bremsstrahlung' was a result of particles dumping energy;
a fusor trades kinetic energy for potential energy (charged particle in
a spherical field).

As others have pointed out, the nscd isn't involved
in dns ttl caching. However, one technique that
the Solaris nscd uses might be useful to ameliorate
any perceived slowdown due to more frequent cache updates. The nscd keeps the most popular (most frequently looked up) items hot in the cache,
retrieving the information before it goes out of date. This might be a useful addition to bind if it doesn't already do this...
A 2 Ghz Opteron running Solaris 10 will saturate a 1Gb network (no jumbo frames) using about 8% of the CPU. For 10 Gb and PCI-Express such an accelerator might be useful... as long as it does ipv4, ipv6, ipsec, vlan, etc, etc.
The one great advantage of doing TCP/IP largely in software is that new features, protections against DOS attacks, etc, are easily added.
Strictly speaking, you mean open standards, not
open source. There's a substantial difference.
We don't need the source for ntfs or cfs; we want
documentation of the disk format and the network
protocol.
Computers using TCP/IP interoperate because they
use the same protocol, not the same open source implementation.
The fact that Microsoft may have used the BSD tcp/ip stack for windows is of course irrelevant.

Let's check some data.
Honda civic hybrid curb weight: 2675
honda civic conv. curb weight: 2560
From http://automobiles.honda.com/models/specifications _full_specs.asp?ModelName=Civic+Hybrid#
Added weight is less than most passengers.
A hybrid configuration acts as a low-pass filter
on the driving cycle power demands.

I'm very impressed with the choices offered in Linux distros... but occasionally I need to use non-open applications (even if it's nothing grander than Turbo Tax:-( ). If there's no common set of facilities (at whatever level) in various Linux distros then we've fragmented the application space to point of irrelevance. Right now we can see that already in the commercial Linux space - it's Red Hat AS or nothing in the US. It's good to not have "One True Package" - but we need something that defines an application environment at enough detail to allow a vendor to deliver an application that will run (w/o recompilation and autoconf!) on multiple distros.
I guess what I'm refering to is the old definition of "open software" - a single interface specification, and multiple implementations. Choice is great - but if it means I cannot get the software I need to use my computer to get other tasks done, what good does it do me?
If I invented a new hammer, it would have to be damn good if it didn't work with anyone else's nails - and if we all invented our own incompatible hammers, we'd spend way too much time making nails to ever get the house built.

If you want to eliminate java, please fly out to mars and destroy the rovers... they're running code written in java.
