Okay, I think this may be it. I'm ready to turn in my slashdot ID. No story has EVER been this lame. Not the dupes, not the slashvertisements, not Taco's marriage proposal. Nothing. This is it. So terrible. I think I'm done. Bye, all.
There are a few problems with using your ISP as your outbound relay: You are now dependent on their SMTP and DNS service. Both for performance and availability. Part of the appeal of running your own SMTP server is that you can operate independently.
For inbound, port 25 has to be unblocked, which eliminates many residential connections. This is less of a big issue, but not ideal.
No. Most of the trades happen on computers in datacenters in New Jersey. You could shut down the NYSE trading floor and it wouldn't have a big impact on overall volume. Some people consider the trading floor to be mostly symbolic. NASDAQ is entirely electronic.
It seems that it is getting more and more difficult to successfully run your own SMTP server. See, for example, this post responding to the idea that a user was going to move off gmail to their own server. Are there any prospects for meaningful SMTP reform that would lower the barrier to entry for legitimate emailers?
DNS has been often criticized as a centralized single point of failure / censorship. Have you been following the development of namecoin and P2P DNS? Are these systems viable in your estimation? How would you improve them or encourage their adoption?
The US Customs department recently created headlines in seizing domains. These seizures appear to be extra-legal (not founded in law), but ICANN has gone along with them. Are those fair statements? Should ICANN's trustworthiness be suspect as a result of this process?
Wall Street as a physical location only has a handful of big financial institutions now. NYSE, Deutsche Bank (40 Wall), Bank of New York (1 Wall), Citi (111 Wall). Many of them have moved to other parts of the the city, including midtown, or even to Jersey City. Many of the buildings have now been converted to residential condos or apartments (15 Broad St., 37 Wall, 45 Wall, 63 Wall, 75 Wall).
If they actually occupied the street it would mostly just piss off the local residents and prompt arrests from the NYPD.
I know that for instance mortgage is a different thing in the US, in Holland the debt stays with you and if selling the house doesn't cover the debt you get to keep paying, whereas Americans can apparently just abandon the house and walk away, the debt is with the house.
This is not true. When people say they walk away from a mortgage, it essentially means they are declaring bankruptcy and their credit is destroyed. If you sell a house below the price you paid for it, you will take a loss and still have to pay off the loan.
Where is the RTG? I'm sure the future lunar colonists will want to be able to locate the RTG. If just to secure it. (FYI, this was part of the ALSEP experiment package)
Look at the records for 144MHz and 430MHz long distance ham radio contacts (two-way contacts; ignore the EME section, those are being bounced off the moon). Note that distances are in kilometers. Tropospheric ducting is occasionally strong enough to even propagate 430MHz FM signals long distances, like the 2672km contact between northwestern Spain and a ship off the coast of Mauritania.
Most countries limit their ham radio licensees to less than 2kW. In the US it is 1.5kW. In the UK it depends on the license level, I think. This is more than enough power to reach long distances, even on VHF and UHF. The reason your FM broadcast radio doesn't reach long distances is basically that broadcast radio receivers are generally very poor in terms of sensitivity. And the antennas used are similarly poor. Another factor is that the US radio market (maybe the UK also?) is fairly saturated in metropolitan areas. When you drive close to the edge range of a transmitter, often another station begins interfering. There is a zone where you can receive neither very well without directional antennas.
Some more reading on VHF propagation is on Wikipedia.
The problem is you can hide different payloads in each, including malware. If a program (or antivirus) treats it as one file type and not the other, then the remaining data will be ignored.
For a demo, see the 38:00 mark. The windows "calc.exe" is modified to simultaneously a valid windows exe, a valid zip archive, and a valid PDF. The same file can appear benign to anti-virus tools even though there is malware contained in the file when interpreted in certain ways.
I didn't say anything about cost. Regarding nuclear, you should look at the power output for one of those plants. They are 2000MW or greater. Although I have to agree on disaster risk.
Who said anything about more expensive? As for "similar heights", the largest radio tower was the Warsaw Radio Mast, which was 2164 ft before it collapsed. The currently tallest radio mast is the KVLY-TV mast which is 2063 ft. This would be 26% taller than KVLY, would be free-standing (unguyed), and would be solid (wind cannot blow through it). This tower is more comparable to a occupied structure.
The current highest capacity wind turbines are 7.6 MW. I haven't been able to find figures on the area proposed for the collector area of this tower, but it is possible that 30-50 simpler and proven wind turbines or 1 to 5 concentrated solar units might be able to replace this tower.
You know they wanted to build one of these in Australia, right? The proposal stalled and it looks like it will not be built.
The idea that we would build the 2nd tallest structure in the world for 200 MW is ridiculous. This doesn't even come CLOSE to being a top producer of energy per power plant. The top 10 power plants in the world all produce more than 6000 MW. Even the largest biofuel, geothermal and tidal plants currently exceed 200MW.
I'm not looking for a technical fix. Of course if you can view it, you can save it and re-upload it. I'm looking for a fix within the system as designed.

The problem is that the AT&T and T-Mobile HSPDA+ frequencies don't overlap. So you would be limited to just 2G data.

Okay, I found this on wikipedia about land use:
A 200 MW power plant with the same 1000-metre-high tower would need a collector 7 kilometres in diameter (total area of about 38 km^2).
http://en.wikipedia.org/wiki/Solar_updraft_tower#Conversion_rate_of_solar_energy_to_electrical_energy
Since this is "only" 800m, it will need a larger collector area (how much larger is unclear).

This is a ridiculous idea. The only structure that is taller than 2600 ft is the Burj Khalifa (Burj Dubai), which is 2717 ft.
