It's clearly insanely difficult to sign your zone with BIND.
It never ceases to amaze me that people expect BIND to do thing outside its scope. Use a configuration management tool to manage BIND. Don't expect every product to include its own bloated incompatible management crap with yet another admin console that I have to load.
I use puppet to monitor changes to a centrally managed version controlled zone database that is automatically deployed and signed any time it is changed. Bad changes are automatically detected and reverted to a known good state via the version control repository. BIND works fine for those of us that know what we're doing.
The creationists stance is that "god did it". End of story. There's nothing to understand because, like anything based on faith, it is fundamentally anti-intellectual. The typical creationist grasp of evolution is less than grade school level; yet, even of those that say they accept it as "fact", even they have a less than stellar grasp of the concepts involved. It's like they get their education from science fiction movies and the discovery channel.
First, natural selection is one of several known mechanisms that drive evolution towards a "goal". The goal is an abstract concept not to be confused with a conscious choice of the participants involved, but one of a self-reinforcing feedback loop that preserves genetic information. The statement, "they don't have any problem with natural selection," is non-sense. If you don't have any problem with natural selection, then evolution is a given.
Evolution is allele frequency shifts in a _population_ over time. Speciation --which is somewhat arbitrary in determination-- occurs when there is sufficiently large shift that the new population takes on a new trait or traits. The traditional determination for this is gamete compatibility or the biological species concept which states that two individuals from different populations are different species if they cannot produce a fertile hybrid. This definition is becoming less accepted these days precisely because of the organisms that can interbreed yet are so different that they can't readily be considered the same. It's important to note that speciation is a product of evolution; it is not the definition.
So, yes; dog breeding is evolution through artificial means. Speciation isn't likely to happen here in the traditional sense because they are constantly cross breeding these dog breeds preventing reproductive isolation. This ensures continuing gamete compatibility. Yet, the morphological traits of different breeds is so great, it's difficult to think of them as being the same. This is more a problem of taxometry than evolution. Humans like to categorize things into discrete categories, but evolution is a continuum. We just come along after the fact and label points along the line that look interesting and call them species.
If you use digest auth, you must store the passwords in either clear text or at least with a reversible cipher. You can calculate the digest using a hash, but then the hash itself becomes the clear text password which makes little sense.
With digest your trading secrecy on the backend for secrecy on the wire. TLS + basic is superior IMO.
Ignoring the obvious troll, I fail to see how VMware helps all with the scenario you describe. How does OS virtualization reduce interdependencies or complexity? If all you're saying is that virtualization makes it easy to have a bunch of identically configured servers (at first), you don't need VMware to do that. You should be using server automation instead.
With propper server automation tools (such as puppet+kickstart), I can deploy any configuration on any supported hardware (virtual or not) in minutes from scratch.
Live migration of VMs is nice, but not essential. What would be even better would be live migration of processes.
I think you guys are missing the point. The parent poster asserted that OS virtualization made apps portable. This is false. VMware isn't providing the portability; the operating system is. If you're talking about being able to create raw disk images of os+app and moving it around to different boxes, I'd argue that you're talking about os+driver portability which is basically only a problem under Windows.
All VMware is doing in a testing environment is reducing hardware overhead which is all OS virtualization really buys you in this case and every other case. Your app should work on all supported operating systems regardless of the underlying hardware anyway. If it doesn't then you're doing something stupid like directly accessing hardware/memory.
If you're using VMware to hide the fact that your app doesn't work on the same operating system on different hardware, you're doing something decidedly stupid.
Yes, it helps, but it really only helps with under-utilized hardware (and this is really only a problem in Microsoft shops). It doesn't help at all with OS creep; in fact, it makes it worse by making the upfront costs of allocating new "machines" very low; however, it has been and continues to be marketed a cure all which is where the snake-oil comes in.
VMware's solution to OS creep: run tiny stripped down VMs with a RPC like management interface (that will naturally only work with vSphere) so that the VM instances essentially become just really heavy weight processes. We are basically coming full circle back to ESX just being yet another general purpose operating system where applications are written specifically for it and thereby defeats the entire purpose of using "virtualization" in the first place.
1. Install/Enable an snmp agent on all your devices.
2. Write a script to walk the network and poll the devices via snmp.
3. Write the information out to ieee802Device records using macAddress as the rdn. Extend the schema as necessary.
You now have a low-maintenance and scalable inventory management system.
BS. Very few college Division 1 athletics programs make any money at all. Far more often they're a major budget hemorrhage justified only by the supposed prestige they bring the school.
It seems you have a serious misunderstanding of the distinction between published information and unpublished (private) information. If I had published all of your aforementioned items, it would be unreasonable for me to be upset that people were reading it and passing it around.
It also follows that trying to charge for something with a near-zero marginal cost is an absurd concept. It's only by fiat of law that this otherwise silly idea has worked at all in the past, and now that technology makes enforcing it utterly and completely infeasible, market forces are rightly destroying it. You might think of it as the universe restoring balance to nature.
So who is it that has a misunderstanding of how the world works again?

This kind of reasoning is exactly why nothing ever gets fixed.
You're right. It's made up of stock holders that only care about their near-term return on investment; hence, evil.
I'll counter your anecdote with my own.
Yes, and server automation lets you duplicate a known good OS+app combination on a whim. What's the difference again?

Ummm... application portability is what operating systems are for.

No idea is truly original. All ideas build upon the ideas of others.
Your entire post rests entirely on unfalsifiable statements, conjecture and unsubstantiated claims about evidence.
1. Install/Enable an snmp agent on all your devices. 2. Write a script to walk the network and poll the devices via snmp. 3. Write the information out to ieee802Device records using macAddress as the rdn. Extend the schema as necessary. You now have a low-maintenance and scalable inventory management system.
Wha? Crossfitters on slashdot? Blasphemy.

You both win the useless use of cat award.
Almost every single one of those issues you pointed out are just election year platform gimmicks.
It seems you have a serious misunderstanding of the distinction between published information and unpublished (private) information. If I had published all of your aforementioned items, it would be unreasonable for me to be upset that people were reading it and passing it around.

So who is it that has a misunderstanding of how the world works again?
I dunno. Maybe because we're living in 2009 and not 1806?
Nonsense. A flat file is a database.
... because it was originally a derogatory term used to publicly shame those that would dare deny/doubt the existence of god(s).
