True but isn't that a part of the normal maintenance cycle of the plant anyhow?
The point is: if the Brown's Ferry plant doesn't make the energy then another plant will have to. In that part of the United States that other plant is quite likely to be coal fired plant in the midwest. Now your kilowatts are coming from coal which adds more carbon to the air, not to mention radon, and if you believe in global warming this increases the chances of a heat wave in the future...
You may not be playing word games but the site that quoted the 88% efficiency rating rating is. There may be economic value to my "waste" heat during the winter in Finland but that same "waste" heat will have no value during a summer heatwave in Tennessee.
Someone has referred people to Wikipedia already but this stuff is so simple that a reasonable educated person can figure it out with proper guidance.
You probably expect something like 85 ~ 90% efficiency. A 17th century French mathematician name Carnot figured this out in an attempt to measure the quality of steam engines. The practical result of his work is an equation that lets us compute the maximum efficiency of any engine which applies heat to a gas for the purpose of generating energy. If you understand the ideal gas law and can conceive of a very long closed cylinder and piston, one end of which is engaged with your heat source you can figure this out too.
It turns out that the only parameters that matter are the temperatures of the gas in the cylinder before and after the work is done. If we define the temperature before we extract work as H and after as C then the formula for the maximum efficiency engine is (1 - (C/H)). Don't forget that this case the temperatures are absolute (Rankine of Kelvin) rather than relative to the something convenient like the boiling a freezing points of water (Farenheit or Celsius).
If we start with dry steam at 1000K end up with saturated steam at 373.15K then our maximum efficiency is 1 - (373.15 / 1000.0) or about 62.685%
TFA has the engineering wrong. The problem isn't the river temperature as much as the air temperature. A nuclear power plant needs to be located near a river so it can have a large supply of relatively cool water to use as a working fluid. The river water gets boiled into steam by reactor water in the nuclear reactors primary coolant loop. This is steam is what turns the turbines and generates the electricity. When it exits the turbines it's still steam, it's just cooler and wetter. You can't return it in this state because doing that would dramatically raise the river's temperature. You have to cool it down before you can put it back. To do that you use a passive air to water heat exchanger. But they're having a heatwave down there. Between the starting temperature of the river and the reduced efficiency of the passive heat exchanger using all three reactors in the plant would heat the river to unacceptable levels.
Unacceptable is not boiling it's probably something in low 90F range because if the mean temperature of the river was over 90F for any period of time you raise the risk of algae blooms and fish kills.
Physical conditions are not preventing the plant from running, environmental considerations are. And if the river's temperature is close to or exceeds the contracted discharge temperature without being heated by the plant then reevaluating the environmental decision may be in order.
It's not just about boiling rivers. It's also about agreements made based on obsolete assumptions. The assumption here was that the air temperature would be below some temperature, say 95F, most of the time. Sadly it leads to a nasty situation where you have to balance damage to one part of the ecosystem against damage to another part.
Many people seem to think that the problem is that the plant cannot run if the river exceeds a certain temperature. That's not the case. The plant takes water from the river and heats it into steam to generate electricity in a turbine. After the turbine the river water is still steam. It may go through some other processes like heating more river water to increase overall operating efficiency. In the end the water ends up in the final cooling stage. Here it passes through a passive air to water heat exchanger. These are typically the cooling towers that you see at a power plant. The air and water trade heat in the heat exchanger. The air gets hotter and the water gets a little cooler. However, the heat exchanger is passive so the water will never leave the heat exchanger cooler than the ambient air temperature. In fact the efficiency of the passive heat exchanger depends greatly on the ambient air temperature. From here the water discharges back into the river at a hotter temperature then it was at the start of the process. The total water used in the process is a fraction river's flow so the net result is that the temperature of the river downstream of the plant is probably a few degrees F warmer than it was upstream of the plant.
The balance that has to be made here is between damaging the ecosystem of the river and slowing down the damage we are doing to the atmosphere. The region is in a heatwave. Regional electrical demand is probably at its highest from air conditioners. And for all of it's problems the nuclear plant is carbon neutral. I'm not arguing that we should build more of these things. But much thought needs to go into the decision about shutting down 1/3 of the capacity of an already built, already functioning, carbon neutral, nuclear power plant. The problem is that the energy to run those air conditioners will coming from somewhere and it's a safe bet that the plants that are generating it are anything but carbon neutral. So the cost of protecting the river is greater damage to the atmosphere which will lead us to the same question more often next summer.
Although I am a PostgreSQL proponent, I've got to say that mysql will happily handle > 100000 rows in a table. Especially if you properly normalize your tables. I ran a virtual inventory application on MySQL which tracked well over 100000 items (assigned and available IP blocks, atm virtual endpoints etc) for a medium sized ISP. I'm currently building a small decision support application. One of my tables has 8000000 rows in it. It's used twice in a query and that query takes no more then 0.1 seconds to execute under any conditions in MySQL.
Encrypted disks will be found, and now it's up to a judge to choose between your excuse why you can't show the court whats in it, and the FUD the procecuter will throw out.
Why does the existance of an encrypted disk allow the Judge/Jury to presume that you are guilty? I think that an encrypted disk tells them nothing. Assuming one: that you are using something decent like CFS or TrueCrypt and two: that you're smart enough to use it for all of your illicit material you've completely denied the prosecutor any evidence that you committed a crime.
prosecutor to computer expert:You can see from these log entries that the defendant made use of the Bittorrent program on his computer on these occasions....
defense to computer expert:did you find any illicit files on the defendant's computer.... No. Are there any legitimate uses of the Bittorrent network say for example to download the Linux operating system from the Fedora Project?
1/3 of the content of an average commercial television show is commercials. If I start watching a one hour program that runs from 10:00PM to 11:00PM on TiVo and I don't want to see any commercials I have to wait until 10:20 before I start watching. That way as I forward through the last block of commercials at about 10:55 I catch up and am watching the last part of the program in real time.

According to Wikipedia the IFR is a liquid metal cooled reactor. In this case the metal is Sodium. Just in case one was concerned Sodium (Na) reacts violently with water: 2Na+2H2O->2NaOH+H2 yielding Lye (NaOH), Hydrogen Gas, and alot of energy. In my high school chemistry class we dropped a 3mm square x 0.5 mm thick chip of room temperature sodium into the drain. This resulted in an explosion forceful enough to blow the drain cap 3m up to the ceiling. I'm just happy that we didn't listen to the person who suggested dropping the chip into a pyrex test tube filled with water. That likely would have violently shattered the test tube.

I agree that this is an act of desperation on the part of the spammers. I think that the filters are proliferating, getting smarter, and becoming easier to use which is impacting the spammers bottom line. For a while I was seeing 50 more messages per day in my spam folder. Lately that has gone down. I think that the target of this attack is not the filter but the user. To the filter this attack is no different than the "word salad" approach that spammers were using six months ago. But the user sees a paragraph of readable prose rather than a collection of random words. I think the spammers are hoping these messages will be misclassified as ham and that will open the door to more spam.
This has been going on for months. State of the art in spam these days is a paragraph of text and a image attachment that contains the actual payload. The idea is that the text is non-spammy and lowers the filters score and the filter cannot "read" the actual spam payload to raise the score. I don't think that this technique will work because the literature they are using tends to be public domain and most of it is pretty old. The problem for the spammer is that this text doesn't really resemble modern English. It confuses people because they can read the text. This is a little different than six months ago where the text was a paragraph of random words strung together. While a person may have to think twice about this new text a Bayes filter isn't reading the message. To the filter all text looks a collection of words. Once the user trains his filter against these new messages the filter will see the old fashioned words as spammy since they don't appear in modern communication. Then these passages become beacons that reveal the message as spam. I think that this attack only works in two cases, where someone mis-classifies one of these messages as ham or if the filter belongs to an English Literature professor.
Paul Graham spoke to this issue on NPR yesterday (Aug 8, 2006) morning. Here's a link to Paul Graham's interview.
The case, of hiding your web travels while at work, was mentioned in this article which was cited in the post.
I recently had an employee, an MIS employee at that, fired. He was using Anonymizer at work. We have a tracking system (Web Inspector) and I kept noticing that he was leaving no tracks.
I consulted with my supervisor and he decided that I should analyze the employee's system. I found footprints, hacking, and a batch file he...
You'll note that, though the company did find out where their fired employee was surfing the reason for his dismissal was the use of the web anonymizer to hide his tracks in the first place. There is a simple rule known by anyone who is a parent. If there isn't any noise then the kids are probably getting into trouble. Take note of that when you choose your stealthing tools.
Actually this is only partially true. While the energy costs for living in the city are higher than living in the country without a car it's really hard to counterbalance the inefficiency of using a 3000 ~ 4000 lb vehicle to transport a 180 lb of cargo. Unfortunately that's exactly what the average person does when they jump in their car to run an errand. On the other hand a fully loaded semi trailer carries 80,000 lb of cargo. Even if the tractor and empty trailer weigh 80k lb then they are doing alot better than the individual person getting groceries in a car.
If I make the assumption that the cost of a useful Kj is constant across electricity and gasoline then your math doesn't add up. I just switched from driving to work (gasoline) to using light rail (electricity) and that has reduced my monthly energy bill by 75%.
Nice detailed article. I'd love to see the results for a vehicle that was less overspecialized though. My ideal test car would be optimized for expressway commuting like a Toyota Camry or a Nissan Maxima. The Jeep is really set up and styled for off road use and as far as mileage is concerned that yeilds a compromise in gearing, frontal area and coefficient of drag. I'd bet that with a Maxima or a Camry or pretty much any street Sedan or Coupe you'd find the mileage peak between 100 and 130 kph (62 ~ 81 mph). I'd love to test this out with my own fleet. Anecdotally I would say that my mileage peak is right around 100 kph and I'm pretty close to the EPA's 14% improved mileage using cruise control over flat or hilly terrain. I think that the big difference is that I'm driving sedans that are setup for the expressway so they are geared to have the mileage peak at highway speeds.
> I'm just guessing, but wouldn't ssh tunnels be readily identifiable if a smart network admin wanted to look for them?
No, the port forwarding is done within the encrypted channel. Rather than thinking of ssh as terminal session protocol that uses encryption you really should be seeing it a protocol for creating an encrypted pipe between two arbitrary nodes. This protocol uses the terminal session authentication methods of the destination. The entire contents of an ssh session are hidden using good strong encryption. A terminal session is just one defined use of the encrypted pipe.
Many security admins don't like ssh because of the port forwarding but realize that they have to take some bad, port forwarding, with the good, secure connectivity for external administration with strong encryption.
If the coffee shop only has an access point then the ISP will have no trouble verifying that the offending material has been eliminated. Since it has been eliminated they will probably not shut off the coffee shop. Consider that by the time the MPAA has notified the ISP and the ISP has notified the coffee shop the user's laptop will be long gone.
My local coffee shop downtown features wifi access. I put in two or three sessions a month for about 2 hours at a session. My coffee shop want's people hanging around chatting and in general adding to the landscape. The offer no services with the wifi. The attendents only know that there is wifi access. If you cannot figure out how to connect then you cannot use the wifi. They won't even reboot the access point. The cost to them is the monthly cost of a DSL line. They seem to have absorbed this a part of the fixed cost of doing business. When I'm there the place is mostly empty. I don't know how many customer's like me it takes to offset the fixed cost. I've seen other wifi users there on several occasions and as the cost of DSL is probably a fraction of a percent of their rent and other operating costs, I'd imagine that they are making their money back.
It's a sad thing that the poster of this choose to take that particular quote out of context. If you read the article Marcus puts blame at the feet of everyone in the process of building security.
Well, as a parent who was childless up to two point seven years ago, I can tell you that the loss of productivity for having a child is real. However, the childless, myself from two point seven years ago include, tend to overestimate the value of this.
As of three months ago the problems Eric described have not been fixed. Two points: First, Eric isn't trying to just set up a printer. He's trying to share a printer using the cups broadcast/autodetect feature; Second, Eric is really aiming this rant at people designing the user interface on OSS. The particular mistakes here are that the cups designers: did not extend the GUI to allow the sharing of printers; and they really buried the options which control this extremely valuable feature.
Even after having said this I'm sure that most people don't get what all the fuss is about since they can probably go through the web gui to manually add a printer in cups. That part is pretty well designed but a cups "server" can also be configured to send out a broadcast packet periodically which tells anyone who is listening on the lan what printers are available. So, on one of my networks when you visit with your laptop you don't setup printers. It's automatically done 30 seconds after you connect to the network.
Does this mean that my Cable company will provide me with a connection and that I could choose a different ISP. To get for example a line where I could run servers and a web hosting farm out of my basement? If that is the case I welcome the change but it would be bad in the short term for the Cable company and I predict that my service would suffer over the short term.
It's not about checking ID's. It's the fact that the details of the law are hidden from the public's view and that there are apparently more laws which were enacted in reaction to September 11th which are similarly hidden from the public's view. If you follow the status of this law you realize that it's something the airlines want because it allows them artificially keep prices high.

That part is pretty well designed but a cups "server" can also be configured to send out a broadcast packet periodically which tells anyone who is listening on the lan what printers are available. So, on one of my networks when you visit with your laptop you don't setup printers. It's automatically done 30 seconds after you connect to the network.

Does this mean that my Cable company will provide me with a connection and that I could choose a different ISP. To get for example a line where I could run servers and a web hosting farm out of my basement? If that is the case I welcome the change but it would be bad in the short term for the Cable company and I predict that my service would suffer over the short term.

It's not about checking ID's. It's the fact that the details of the law are hidden from the public's view and that there are apparently more laws which were enacted in reaction to September 11th which are similarly hidden from the public's view. If you follow the status of this law you realize that it's something the airlines want because it allows them artificially keep prices high.
