Comment While there, if you do go Kayaking (Score 1) 278

Well, if you do spend time in Fall City, when kayaking or canoeing, go upstream and put in on the Snoqualmie river at the turbine house just past the base of the falls. It is a nice half day float, but don't bother going much downstream of Fall City as the river gets really slow to almost being stagnant and winds around forever before you get to Tolt River Park at Carnation.

Having been there, Fall City probably needs an AA program more than it needs a internet addiction program

Comment Re:"for civilian use" (Score 1) 167

There are fundamental engineering differences in how the reaction is propagated in the RBMK Chernobyl rector vs the Three Mile Island(TMI) Pressurized Water Reactor (PWR) (http://en.wikipedia.org/wiki/Pressurized_water_reactor#Moderator)

The US National Reactor Testing Station which is now the Idaho National Lab performed the Loss of Fluid Tests (http://en.wikipedia.org/wiki/Nuclear_fuel_response_to_reactor_accidents#LOFT) to better understand what a loss of coolant accident would mean (http://en.wikipedia.org/wiki/Loss_of_coolant_accident). Understanding that the loss of water which acts as both coolant and moderator for fast neutrons means the reaction cannot continue in a PWR reactor. The prevention of a Chernobyl like accident in the TMI reactor is far beyond 'Luck' as it was designed into the PWR from years of testing that occurred. The intent was to achieve what is known as 'Passive nuclear safety" (http://en.wikipedia.org/wiki/Passive_nuclear_safety) which is a driving fundamental engineering for all modern reactors.

The Chernobyl reactor did not benefit from this fundamental engineering in the reactor design, and to top it off, it was revealed that they were performing a very risky and unwise test of testing an untested emergency core cooling system (http://en.wikipedia.org/wiki/Chernobyl_disaster#Planning_the_test_of_the_safety_device) with many unconfirmed assumptions of turbine momentum and pump power being made used as excuses to perform the test on a full scale power reactor instead of in a lab reactor or modeling prior to accident with safety contingencies set up to prevent excursions. This combined with the low power level in the reactor and the impatience to approach such a condition properly, they added water and MANUALLY REMOVED THE CONTROL RODS to increase power in a xenon neutron poisoning situation, set them up for the catastrophe. The RBMK reactor was taken far from its normal mode of operation for this accident to occur, even with its less then modernly acceptable design and construction.

Such testing activities here in the US are probably criminal, someone from the NRC or with that knowledge would have to confirm that though.

Libel statements about shift workers at TMI DO NOT CONTRIBUTE to ANY good analysis and lessons learned for the Nuclear Industry.

As for the main topic's discussion of the accidental disclosure of various nuclear facility locations, most of them were probably unclassified anyway, and knowing where something might be (as stuff gets moved and the disclosed locations can change) is not even most of the battle. Physical security at these sights is probably set up on a military as opposed to a police scale, and organized with support from local military assets. The federal government may have the Department of Energy manage nuclear materials for the Department of Defense, but the Department of Defense still owns the materials. As for civilian locations, the guard forces are still fairly military like in nature, with well planned protocols for various events. This accidental disclosure probably does not increase risk in any significant way.

Comment Some home (castle) defense options (Score 1) 828

Well, a castle with a long straight entrance can use large rolling objects to crush the invaders with fairly good efficiency.The properly designed crusher will be roll-able back to a reloaded position for the next wave. If properly set up, a similar entrance could be turned into a water channel for temporarily diverted water sources to was the bad guys away.

Moats with pointy objects (spikes) concealed in them has had a fairly good deterrent. The moat must be at least 50% longer than two of the taller trees lashed together.

Moats with moat monster wildlife crocodiles, piranha, saltwater moats with sharks, jelly fish, etc have some effectiveness as long as the said monster(s) are in the mood to be pestilential.

Trap Door draw bridges may be effective traps.

Sharp Shooters with High powered crossbows have been good at sniping leaders of besieging forces, people manning siege engines, and Calvary charges to create a hole in their charge.

Mechanical power provided by waterwheels (~5hp) and windmills (~10 to 15hp) could be used to drive GNASHING SPIKED POWERED WHEELS OF DEATH HA HA HA HA, with reasonable effectiveness.

Anyway, it is not like I gave this any thought.

What he did could very possibly be considered assault, or in today's climate of legalities a bio-terrorist attack. I believe the only reason nobody go up and kicked his ass is because of who he is, which is probably the only reason why he has not been arrested by DHS. They arrest other people for mailing unidentified powders as a joke now!

Making a point about how lame some parts of the world can be with diseases doesn't cut the mustard for this kind of stunt, anyone here at slashdot pulling this off would probably be arrested.

Comment 9x80's are nice (Score 1) 1055

It definitely has it's nice points. With the three day weekend every other week, usage of vacation time is more efficient. It gives a weekday during which you can run business hour errands , and if a project is in an emergency, you can squeeze in some extra time to complete things. It is also a nice thing for me as a parent to use the time to go on a lunch date with my wife while the kid is at daycare. Since I consult, I see several schedules, and I like the 9x80s better than most. 4x10's seem too long some days and the regular 8 hour day schedule lacks the nice 3 day weekend.

I hope this schedule works out for you, as everybody's life is different, but I suspect you will find it a nice change.

At my first exposure to the 9x80's schedule the company split into two shifts with half of the company having one Friday off, and the other half having the other. While this may complicate holiday with vacations sometimes, having Fridays with only half the people there made for a more peaceful and productive Friday. But not all companies will split like that.

Comment Patent Spam (Score 1) 284

Here is a crazy idea, using the flaws of the current patent system, patent spam and then sue the pants off of the spammers for using your IP without your permission, and simply withhold permission from everyone. If enough people file patents for spam in all of its various forms, we should get this problem licked.
