You really don't want to put normal users on the AFS file servers. Managing volumes across these machines would also be a headache more painful than you can imagine. AFS also has very poor handling of server outages and volume replication exists only for read-only volumes.
One reason for the connection between the two networks is for flight information, such as altitude, heading, position, etc. This information is displayed on the entertainment network in your seat back, but the data comes from the critical navigation systems. Such information only needs to go one way (to the entertainment network), but to transfer that information there does need to be a connection somewhere.
At least in T1, there are 8 windows for each strand (thread), so 32 windows total. The register file design supports fast window switches within a strand (3 cycles) and can switch between strands on every cycle. The megacell guide included with the RTL has a detailed description of how this really works.
The T1 pipeline is just 6 stages (not terribly deep), while the T2 just adds a bypass stage.
The most recent release of the T1 code has a few options for removing functionality (dropping to 1 core and 1 thread) such that it will fit on some of the larger available FPGAs.
There is a successful FPGA project for the T1. The OpenSPARC engineering people were at FCRC/ISCA this summer demoing the T1 running "adventure" on an FPGA board.
I can only hope that the pilot used good judgement in choosing to wait until the plane had parked at the gate. I would guess that the interference was temporary noise on their headsets.
I read somewhere (too lazy to find the reference) that part of the reason is because cell phones don't locally play back your voice on the speaker. Hence, to the person on the phone, it feels as if (a) their ear is blocked and (b) the phone is not capturing their voice. By contrast, landline phones apparently do leak some of your voice back over the speaker and so you feel as if you're talking loud enough.
At the end of a recent flight I took to Austin, TX, the captain got on the intercom and admonished the passengers for leaving a cell phone on. He said they experienced interference on their radios from a passenger's phone (presumably those GSM chirps).
Not true. Transistors at really small dimensions (e.g., 32nm and 22nm processes) will experience soft breakdown during (what used to be) normal operational lifetimes. This will be a big problem in microprocessors because of gate oxide breakdown, NBTI, electromigration, and other processes. Even "solid-state" parts have to tolerate current, electric fields, and high thermal conditions and gradually break down, just like mechanical parts. Don't go believing that your storage will be much safer, either.

It's a cash cow!

I thought the problem was a slow net.

No, that coveted spot is already reserved people who truly do reshape traffic: backhoe operators and anchor-dragging boat captains.
> Why can this be the case in these fields but not in other fields of science?
Perhaps because you can replicate experiments in many other fields, but you only get to dig something up once.

Be part of the solution, not the precipitate.

The name you are thinking of is the "tick-tock model."
Let's run it through legal.
Heck, our government can't even secure its machines from itself.
One can always try to hold the roads responsible.

What does this have to do with fish in a barrel? I just don't get it, zonk.
I used to go to a bank in eastern PA whose drive-up ATM dispensed both cash and change to the penny. Coolest thing ever.
The 4th commonwealth doesn't sound nearly as catchy. :)
Hey, not so fast!
PA recently became the 50th state in the union to put their laws online.
You must not have cats.
