Nagios is probably the easiest to use network monitoring system. That doesn't mean it's particularly easy, just that the others are worse. It breaks down when the network has trouble though; if a significant number of host are unreachable it takes forever for nagios to figure it out. That tends to be exactly when you need it the most.
Hiding is only good if it actually works. Once you leak information about the internal encoding to the program, you have lost. Such as the length of a one-character-string sometimes being 2 -- have one program depend on that, and you can never change the supposedly hidden encoding. Of course noone would be stupid enough to return 2 when asked for the length of certain one-character-strings...
If electric demand "off-peak" suddenly goes through the roof because everyone is plugging in their car at night, it it still off-peak?
You are seriously underestimating the difference between peak and off-peak. Anyway, it would be great, because it's much easier to design an electricity network where base power = peak power.
You're serious!?!? Give the killers what they want, that's what you're advocating here!?!? They kill innocent people and your reaction is "give them what they demand"? What about the next time and next thing they want? The time after that? Why should they stop if it gets them what they want? What if they want you and your family dead, or your countrymen? What if they demand you live by their laws? Will you give up your freedom and your life to appease them, or is it only ok as long as it's someone elses' freedoms and/or lives that you don't personally care about?
You have convinced me. We must not give up fighting the US.

Trying to get every piece of software in an open-source format would be extremely hard to impossible.
There is nothing preventing you distributing proprietary software as source code. In fact, it would have made a lot more sense if copyright only applied to software distributed with the source code. That would have made the book analogy a lot more compelling.
It's dead easy to control, track, trace, and monitor IPv4, and even to do automatic man-in-the-middles. It is in fact so cheap that some ISP's do it just to insert advertising. IPv6 won't change anything about that.
The Chinese are using NAT very extensively already. Residential customers don't get a public IP address. If China is running out, that means that businesses can't get addresses either.
The US hasn't started feeling the pain even for residential yet, AFAIK. Europe is seeing deployment of NAT in some mobile broadband networks, but so far not much in regular broadband.
In fact, with this vintage you would have experienced the RPM 3->4 fiasco first-hand.
I don't recall it. I probably did rpm2cpio|cpio -I.
And anyway, RPM isn't my baby. I just think it's silly that.deb is thought of as such a superiour format, when in fact the archive format is worse and the header is practically identical. It's dead easy to generate both formats without using the official tools.
- No easy way to get the contents of an rpm out. The cpio tools at the time kept crashing randomly. I'd never even heard of cpio at the time. Why use that format?
Because it's actually a standard, whereas tar is a bunch of different flavours (most of them very limited). Yes, cpio has a crap interface, but the archive format is excellent. pax reads it. Someone really should add support for it to tar.
- An assumption that you'll be running build scripts as root. What sort of thought process led to that?
There is no requirement that rpmbuild must be used to generate the rpm. It's just a cpio-archive with a header.
- The RPM 4 upgrade RPM from Redhat, packaged in RPM 4 format. Think about that one for a while.
That has nothing to do with the format.
If you haven't had a play with rpmbuild, I suggest doing so. It's probably moved on since I last used it though, so perhaps they've cleaned up their act.
I've packaged software for my own use since Red Hat 6 at least.
So my small bit of M$ stock should go up in value, yes?
Not necessarily. You'll end up with a larger slice of a smaller pie. Your stock changes value only if "the market" decides the buyback is a particularly good or bad idea.

Cacti isn't very useful for alerting, just as Nagios really doesn't work well for graphing (one of its more annoying shortcomings).

Never! Why settle for the lesser evil?

Thanks to online casinos, poker is getting solved at a very quick rate. In a few years online poker will be basically unplayable by humans.

You are seriously underestimating the difference between peak and off-peak. Anyway, it would be great, because it's much easier to design an electricity network where base power = peak power.
Therefore, on average, turning off a computer each night will shorten its lifespan.
Life span isn't a problem for computers. >90% of them end up going to the land fill in perfect working order.
Turning your computer off for a night will save about as much energy as your car uses while driving 200-300 meters.
So get rid of your car too. It's ridiculously inefficient.

or thinking that an item is worth more/less just because of it's previous owner.
A previous owner can give you the opportunity to tell a story. Stories are valuable, some more than others.
$2500 for a virtual instance? You can get quite decent complete servers for that.
Well, as I have stated in another comment, I'm all for cutting the US off the Internet until they learn to behave.
No, just one of them is the choice, because that's how it worked out.
I don't disagree with you. I'm just saying that Jobs would be even worse.
Indeed, let us all be glad that Microsoft won the PC war instead of Apple. Jobs would have been worse.
but then the owner of the public IP still should be required to police the hosts on his/her network.
It's not his network. He's just the ISP.
Plus, IPv6 doesn't solve any other problem besides address space. It doesn't solve:
1) I don't have a pony.
They do. Residential customers don't get public IP's. Which makes this announcement all the more newsworthy.
The majority of spam comes from the US. I'm all for cutting the US off from the Internet. That should buy us a few more years if we reuse the IP's.
It's dead easy to control, track, trace, and monitor IPv4, and even to do automatic man-in-the-middles. It is in fact so cheap that some ISP's do it just to insert advertising. IPv6 won't change anything about that.
You're likely seeing NAT'ted addresses. If there are a thousand hosts behind a NAT, it's likely that at least one of them will be infected.
The Chinese are using NAT very extensively already. Residential customers don't get a public IP address. If China is running out, that means that businesses can't get addresses either.
The US hasn't started feeling the pain even for residential yet, AFAIK. Europe is seeing deployment of NAT in some mobile broadband networks, but so far not much in regular broadband.
