It is used only for administration, serial console for a few devices, crunch some log files, etc. It used to be a backup mail server as well. All well within it's capabilities. It isn't likely to run at high load very often. The run like a tank feature is it's primary reason to be. Since it is the machine used to diagnose problems, it's helpful that it is unlikely to be the machine with a problem.

Sometimes, old used equipment is exactly the right answer, sometimes it's a terrible idea. The production servers are much newer machines.

Ha. You make me laugh. People such as yourself have bad memories, or lived in some kind of sheltered environment. Every generation is convinced that the generation after them are the spawn of satan, and when THEY were that age they were all just perfect angels, or at the very least a HELL of a lot better than the current lot of miscreants. The attitude you're projecting has been common for at least the last 60 years.

Uhh.. when _I_ was that age about 20 years ago people were hacking into the computer science workstations, sniffing passwords, hacking root, running a bazillion processes on the box, etc. The only thing that's changed is now it's Linux machines, not SunOS machines.

We consolidated about 20ish old servers (and added new systems) in to two Dell R720xds that are VM hypervisors. Not only does this save on power n' cooling but it is way faster, more reliable, and flexible. It is much easier and faster to rebuild and stand up a VM, you can snapshot them before making changes, if we need to reboot the hypervisor or update firmware we can migrate VMs over to the other host so there's no downtime. Plus less time is wasted on admining them since there are less systems, and they are newer.

On top of that they have good support contracts, and some excellent reliability features that you didn't get on systems even 5ish years ago (like actively scanning HDDs to look for failures).

Big time win in my book. Now does that mean we rush out and replace them with new units every year? No, of course not, but when the time comes that they are going out of support, or more likely that usage is growing past what they can be upgraded to handle, we'll replace them with newer, more powerful, systems. It is just a much better use of resources.

If your users can't play nice together, the solution isn't to treat the place like a prison with automated systems enforcing a hard and fast set of rules.

The solution is for users to create their own enforcement. If some guy tries to take all the resources across your network with distcc, then the people affected should be able to notice that and tell the guy to knock that the fuck off.

In other words, give the users the freedom to break stuff, but also the knowledge to find out who'd breaking their stuff. It'll serve them far better than creating a walled garden where someone else has the responsibility to enforce social rules.

Slashdot and reddit work this way. Neither go around trying to enforce how people behave, they give the users the power to do that themself.

Seems like you are trying to work out a solution to a problem you don't have yet. Maybe first see if users are just willing to play nice. Get a powerful system and let them have at it. That's what we do. I work for an engineering college and we have a fairly large Linux server that is for instructional use. Students can log in and run the provided programs. Our resource management? None, unless the system is getting hit hard, in which case we will see what is happening and maybe manually nice something or talk to a user. We basically never have to. People use it to do their assignments and go about their business.

Hardware is fairly cheap, so you can throw a lot of power at the problem. Get a system with a decent amount of cores and RAM and you'll probably find out that it is fine.

Now, if things become a repeated problem then sure, look at a technical solution. However don't go getting all draconian without a reason. You may just be wasting your time and resources.

> What do you do if the movie you want to watch hasn't been released on DVD either?

A much much MUCH smaller problem.

Your own remarkably obscure examples demonstrate this.

Streaming requires permission from the relevant publisher THIS SECOND. That permission can be REVOKED an hour from now.

On the other hand, what's available on physical media represents everything that was consented to EVER. That consent can NEVER be revoked. We can trade old copies of that media until the publishers get blue in the face.

"It was never published on DVD" is a much smaller problem than "it is not currently available for streaming".

Even Egypt doesn't want to deal with these people. That's why the Egyptian side of the Gaza strip is also closed.

From their point of view, Gaza is full of the same kind of nutbags that they just got done deposing.

Jordan and Egypt both could probably end this mess tomorrow by claiming the respective territories bordering their countries. They don't want the Palestinians anymore than anyone else does.

Two words: New Releases

Netflix streaming is effectively a replacement for all of those channels on cable that are dominated by reruns and old movies. Netflix streaming is great for that kind of stuff. For anything else, it's pants.

For new releases, you will simply have to go someplace else.

There is no such thing.

Otherwise, there simply would not be any Palestinians left by now. The problem would have been sorted out by simply having exterminated everyone from the occupied territories.

THAT is what genocide is.

Really? You're going to try and pull that stunt? This territory was a well settled part of several empires starting with Rome. The idea that the people that happened to reside there in 1940 had "American Indian" notions of land ownership is absurd and assinine.

These people were former subjects of the Ottoman Empire.

Contary to popular belief, broomsticks can't fly and are not aerodynamic.

If 16th century India could do it... (why a person would believe that the warhead has to be the frontmost part of a rocket is beyond me, given that the interceptors themselves aren't built that way - yet the entire logic behind the interceptor's detonation system relies on that assumption)

In any case the missile will miss its intended target if it was hit by shrapnel.

Nope.

1. A hit by a few pieces of shrapnel each weight no more than a few grams is not going to have a noticeable impact on something that's dozens of kilograms moving at roughly half their speed. It's simple physics.

2. The warhead is the whole point. A warhead-less rocket won't penetrate your roof. If you're out walking in the park and it lands on your head you might get seriously injured, but apart from that. no.

3. What are you talking about? The payload of the Tamir interceptors is is 11kg, that's no secret. And again, it's not designed to work by concussion, it's designed to work by shrapnel. The energy of the explosion is mostly spent in the process of creating high velocity shrapnel fragments.

Beyond that, the length of time of any exposure here to any explosive force is simply miniscule. The rockets pass each other at a rate of 1200 meters per second - nearly half the speed of the explosive shrapnel itself. Even if they passed directly past nearly grazing each other (which is grossly implausible), they'd only be within a meter of each other for less than two milliseconds. And even things that are right near explosions the whole time get surprisingly little push from blast shockwaves (Mythbusters did a full episode about this). Relevant push from explosions requires confinement of the gasses.
