They did a test and the beam vaporized like a 40 M long copper tube a mm wide or so. Now they have a large graphite tube encased in like a foot of concrete to stop the beam and they scan the beam across it so it heats up evenly.
that is an awesome deal. One thing to worry about with old P4 stuff is how much power it will use. Each of those uses probably $15 or more each month in electricity depending on where you live. It probably does not come out of your IT budget, but it still costs the company money.
I doubt with only 150 people they would want to spend the money to have a server at every office in case that offices link went down. I agree wholeheartedly that the level of redundancy talked about is overkill. Also will WWW, mail, DNS,... even work if the line is cut regardless if the server is in the building?
The OS stores a hash of the password on the hard drive. When you log, in the OS calculates the hash of the password you typed and compares it to the one saved on the disk.
I am not an electrician, but what happens when your device that needs 10-15 amps starts drawing 25A and melts its power cord since the breaker doesn't trip?

I make people cables for free and have them return the one they just bought at best buy. It costs me next to nothing, but best buy looses a fortune.
Its not as simple as you think when your 92 Tbps router is actually 72 16 slot routers connected together with fabric chassis, where each 16 slot router shelf is over 1 thousand pounds and the size of a 42U rack. Then you still need to connect switches with lots of ports to it. . Look at Cisco's data center products, if you are looking to build a data center, for example the 18 slot Nexus 7k. . The 18 slot Nexus 7k can support 512 10 gig ports on a single switch which is physically smaller than a single one of the 72 router shelfs of your 92 tbps CRS-1 requires, not to mention all the fabric chassis needed to connect your CRS-1 together.. To get 512 10 gig ports it would take an 8 shelf CRS-1 multichassis configuration. . For a back of the envelope test you can put 256 Cisco 6513 chassis on a 512 port nexus 7k with redundant 10 gig links and then each 6513 can support 11 slots * 48 ports = 528 ports for servers. That gives a total of 256 * 528 = 135,168
ports in the system. After this is setup, you now have about 128 42U racks full of over 100k blinking lights.
They should also fire the person who was responsible for having a sprinkler installed above a transformer, exactly how is spraying water on a transformer going to help in a fire?

they make natural gas powered generators that are capable of powering your house when the power goes out.
its more like over 50 nonillion addresses per person

I ran the numbers once myself. It does not cost a significant amount more to run the CPU at 100 pct versus idling the computer.
after a little autopager work, it looks great to me :)

and UPS pays tax for that anyways.
I wonder if it is, I will have to ask my prof if there were any studies done on that.
I remember from my psychology class that what religion you follow has no heritability, but how religious you are is at least partially heritable.
Also, Intelligence has a negative correlation between children and parents, at least according to Wikipedia.

the max gig ports you can have on a CRS-1 multichassis is 55,296 using 16x Sip-800 full of SPA-8x1GE-V2.

No, we AND the lawyers win.

3 feet, in my state we must give them 1 foot of clearance on each side.
