You would think that an email tax would stop SPAM, but YOU will now have to pay the tax receiving all the SPAM. Then if your system (or your neighbor using your wifi) is infected with a bot net you'll have to pay the tax for sending all the SPAM!
I have read that some of the newer SSD have only 500-1000 P/E cycles (eg. Kingston V300, Samsung 840), but I don't have proof. It is well documented that most of the current MLC drives have 3000 to 5000 P/E cycles while may of the SLC units are 100000 (eg. Intel X25-E, SuperSSpeed SLC S301).
You have to buy and use the correct type of SSD for your application. A new TLC SSD should not be used in any write intensive application (eg. ZFS ZIL) but it may be great for that new fast laptop that can use the speed and does not do a lot of writes to disk. For most standard uses a good SSD will outlast the laptop/desktop where it is installed. The key for good SSD use is detection of pre-failure (SMART is a good start). The SSD is now a consumable part, just like the battery or brakes on a car. We all know drives fail, but standard hard drives don't have the same fixed life expectancy as an SSD.
I have nothing to do with this site, but it looks like a good place to look.

At that age I remember having a great time at summer computer camp in Vermont (2 weeks sleep away) in the early/mid 80's. I had the best time doing the non-computer things (like sailing on Lake Champlain), but I always did as many computer related activities/classes as I could. We got to use the newest Commodore CBM with Pascal! As an advanced class I also learned Fortran on the big IBM (System/34 I think). I don't use the old programming languages any more, but I'm still happy to take out a sail boat!
If you're going to visit the USA I think you should focus on non-computer activities. Like visiting the great national parks, such as the Grand Canyon, Yellowstone, and a hundred others that are unique to America. Spend time programming nearer to home. You can always play with a computer in a windowless closet anywhere!
One of the photos shows a Cisco 2950T-48 that provides 48 10/100 ethernet ports with 2 GigE uplink ports. This seems like a simple setup for lots of tables. Drop a switch at each table and feed run one cable back to the core switch for the area. If Cisco provided 300 of these switches that gives you 14400 100meg ports for users. Then a few core switches with a stack of non-blocking GigE ports and some 10GB or 40GB uplink ports to the core routers.
Easy... I'm sure several companies (or universities) had similar setups. The amazing thing is the built it as a temporary setup.
The real job is providing safe power and cooling for all users.... maybe next time they can provide PoE for everyone and require "green" computers!

Cisco is also doing the same thing. They are fixing only the "current" IOS versions for "current" routers. This means MANY routers currently installed and running the Internet can not be patched because cisco JUST ended support before the patch (eg 7500 backbone routers and MANY others) or the routes do not have enough memory to run the current 12.4 software (eg 1700/2600/3600). This is cisco's (and Microsoft's) way of saying "you should pay more to 'upgrade' to new software/hardware (even if your current stuff works)". I can understand cisco not supporting the old 2500/1600 routers.... they should be replaced even if they work correctly!
I love the end of the story "CBS 11 News emailed Simpson about the raid, but as of Thursday evening he had yet to respond"..... I wonder why? May be the FBI took their mail server too?
Assuming you have a computer "room" (enclosed space)....
Supplies (plus tools):
Duct tape (you have it somewhere in your desk)
Some 2x4 wood (get it from a dumpster or construction site)
New circuit breaker (take it from another unused circuit)
Cheap 25000 BTU window AC unit ($600)
1) Convert your 20A circuit from 120V to 240V, or move to Europe, or get a smaller AC unit.
2) Cut a hole in you computer room to the outside. This could be a hole to the real outdoors or just into another room. You don't care because the computers are all you need to deal with for this project. If this hole happens to be into another room it will still work just fine as it will move heat from the inside of your computer room to the outside (into your office or where ever).
3) Use the 2x4 wood to build a support for the window AC unit in your new hole. You don't want it falling out, then you'll just have a hole in the wall (another cheap cooling idea).
4) Install the cheap window AC unit into the hole and seal with the duct tape. Plug it into the outlet and turn it on.
5) Profit!...I mean, you're done. If you need redundancy then repeat the procedure for a second unit (assuming you have the power, or a long extension cord).
This is not a joke...I have seen this setup in a few places (eg. basement computer room), it's a crude setup but the computer room is cool.
Note, if the AC unit happens to be next to your office cubicle then you might want to move first. Don't forget to put a large trash can under the back of the AC unit as it will drip condensate all day. Also in the winter, please don't walk on a the rug in your computer room as you will build up a big static charge because your humidity (RH) will be about 0-5%.
For about $600 you can get a 25000 BTU window unit. With that you can cool about 7KW of computers. If you only have 120V then you can get a 15000 BTU unit for about $400 and cool about 4KW of computers. Don't forget to include the heat from your UPS (assuming you have one).
If you need better humidity control, put a big bucket of water in the room for the winter, and add a space heater for the summer (for reheat, you run both AC and heat).
Now if you made a mistake in your post and have a $6000 budget then you can get a ductless split system and have it installed (unless you are in a real office building and can't get outside access).
Almost no one gives ReplayTV any credit. They had a far better product than Tivo or anyone at the time.....I guess it's the old Beta vs. VHS....The first Replay units cost way too much but they changed everything.
Now with HDTV on cable/Sat (OTA is too hard to deal with) I'm stuck (for now) with the Motorola box on Comacst, and with my D-VHS I can record the HDTV movies at 15-30G per tape. The Motorola DVR does work most of the time execpt when I have to reboot it because it locked up. Nothing works as well as the old ReplayTV 3000 units (I still have two running)!
It's like I'm back in the stone age again. My "cable ready" TV does not work and I'm using video tape (unless I want to compress the hell out of HDTV).
ReplayTV says they have a new software solution for the PC soon...sounds like another HTPC setup.
This all proves no one can survive with just great technology, you have to have good marketing and deals with the bigboys (the reason Tivo is almost dead without EchoStar, and ReplayTV is basicly dead).

Don't forget about Write Amplification. It can help kill a drive faster than total bytes written:

I guess the easiest way to "support" IPv6 is by name alone...
ipv6.slashdot.org = 216.34.181.48
No IPv6 AAAA record for ipv6.slashdot.org

So will they just get their own area code? Say 466 and start all numbers with 4 (yes that's GOOG).
