Can't resist tooting my own horn. These are from my Klein bottle website:

    TOPOLOGY CONSULTANT Part-time design of low-dimensional manifolds in glass, wool, plastic, titanium, niobium, pentium, and unobtanium. Ideal candidate is fresh out of college with 20 years experience in applied topology; and can solve Poincare's, Heawood's, and Hodge's conjectures. Pay & benefits are epsilon above unemployment. Compensation package includes trillions in worthless stock options.

    GLASSBLOWER Construct borosilicate manifolds using lampwork. Handy with glass lathe, oxy-hydrogen torch, and bandaids. Must know the usual cuss words to describe breaks & cracks. Experienced in minor burn treatment. Special bonus if you know the difference between inside and outside.

    MANIFOLD OPERATOR. Curvaceous, conformal Riemannian vector field desires normalized Ricci tensor with nice eigenvalues. Will relocate within proper metric space. No polymorphic permutations, please.

While it certainly saves the average traveler from having to guess the queue length and service rate for themselves so they can estimate the wait via Little's Law ( http://en.wikipedia.org/wiki/L... )
It is hard to see how it manages to not be confused by people standing around the entrance and then walking away rather than in, or separate those speeding through the Priority or Pre-Check lines from the regular lines.

It would seem a simple electric eye counter or just giving the guy who sorts you into lines a clicker might do just as good a job. So while I don't like hopping into the tin foil hat explanations too quickly it is hard not to suspect that maybe this is just a cover story for the fact that they are indeed using it for surveillance purposes.

But then they already know everything I am doing in the airport tracking my phone doesn't personally make me any more under their eye than I already am. Not that I like them gathering all this data and lying about what they keep, I'm just not sure this actually adds to the degree I have already had my privacy compromised by the government.

Except the article said we run out in 30 years

Earth’s carbon budget—the remaining amount of fossil fuels that scientists calculate can be burned without destroying the climate—will last only about 30 years at the rate we’re going.

The 2035 date had to do with bringing everyone to the US standard of living.

Close enough that we have to DO SOMETHING NOW!, but far enough that no one will ever be called to account for being wrong, but not so far away that it's not in our life time and can be ignored. Having lost track of the number of such deadlines for the point of no return that have already passed in my life time let me just say I am a little skeptical.

And you know the Indians, the Chinese, and many others could care less and are going right on growing their populations and carbon production and there is no chance they will do anything but grow for the next 30 years. So if the author is right and we have only that long before we have irrevocably ruined our environment, then the choice for those of us in the industrial world is clear.

Enjoy all the vacations and recreational activities you can now. No seriously, if they are right then we are doomed, so you might as well enjoy it while you can, and they are wrong then you will have the last laugh while they sit around entertaining themselves doing the crossword puzzles, while they suffer without air conditioning.

It is both modeled on Napoleonic Navel Fiction while at the same time being physically accurate withing the constraints of its sci-fi universe. Accelerate at full speed for an hour in one direction, well then it will take you an hour to come to a stop. Long trips at high fractions of the speed of light have shorted subjective shipboard times. The light speed time lag in sensors and communication plays significant tactical and strategic roles in almost all the battles.

Hi gang,

        Thanks for the reports of stale gasoline - I'm convinced. Tonight I'll head out & recycle my old gas. The problem isn't getting things together; it's keeping it all up to date & ready. Your comments hit me in the right place: be prepared.

        I'm associated with a ham radio emergency group; the rule is that the station's equipment must be immediately ready for action. In an emergency, you don't have the luxury of stringing a cable, or figuring out which power supply can work with which rig. If the transceivers aren't wired up, tested, and set to go, they might as well be underwater. Same's true for on-the-air skills. You gotta check into the 2-meter net at least every month, or you'll get rusty and screw up when things get hot.

      And so it is with earthquake readiness. It's not enough to put away a survival stash and let it molder. Gotta keep things fresh - gotta keep my skills sharp.

Best wishes,
-Cliff
        ps to ksmithderm ... sure, I've got Klein bottle hats (and Mobius scarves). They're on m'website.

by Cliff Stoll (#47743541) Attached to: Slashdot Asks: How Prepared Are You For an Earthquake?

Background: I live on North Oakland, next to Berkeley, in the Rockridge section. Urban, detached 2 bedroom house about 100 years old.

We bolted down our house, fully reinforced the stemwalls, and installed shearwalls. For our little 2-bedroom bungalow in Oakland, this set us back around $20,000. Earthquake insurance seemed outrageous (around $2,500/year, with very limited benefits). Along with the earthquake retrofit, we set aside a few cases of food & twenty 5-gallon jugs of water. A 2Kw Honda generator. Radio, flashlights, FRS walkie-talkies, etc. Small amount of medical stuff.

Yes, I have onsite and offsite backups (that's easy); the real problem would be connectivity after a quake. There's probably a hundred telephone poles between my house and the central office.

Some challenges: Keeping food & water fresh is a problem - cans get rusty as water condenses on cold surfaces. Some camping food goes bad. MRI rations taste, well, horrible. We should replace water & food annually, and generally forget to. (We discovered diapers in our earthquake stash, left over from when our college kids were infants)

    Storing gasoline for the generator is a problem. I'm told that gasoline gets stale after a few months (is this true, or an urban legend?). It's a pain to lug a 3 gallon gas can around, and it's not something I want under my house. (I store it in a shed, where it's out of sight & out of mind - so I rarely refresh it. Is there a small, 5 or 10 gallon under-ground gasoline storage tank?). I should start and exercise the generator every month; it's more like every two years or so. Our experience in the 1989 quake was that gas stations can't pump after an earthquake (no power).

  Our neighborhood's quake group (the Oakland - Rockridge Shakers) meets every summer, and the earthquake drills have been quite useful - we've had several fun practice sessions, where we hunt for human dummies hidden around the neighborhood, search for downed wires, and practice using walkie-talkies. Afterwards, it's a block party, and we compare notes while sharing lunch.

    My home business, Acme Klein Bottles, lost two glass Klein bottles in last night's quake. Both fell off a shelf and shattered on the floor. Good lesson: keep my glassware stored down low, with holders to prevent boxes from shifting. Since most of my glass Klein bottles are stored under our house; a major local temblor that destroyed the house would also wipe out the business.

Getting lots of people running Tor even if they don't need to, even if the implementation may not be the "best" possible, for various definitions of best, is that it dilutes the number of users using Tor for "bad" things.

I don't know what the percent of users of Tor are using it for the standard list of things the government needs to save us from, but you know that eventually the argument will get made, which owing to the nature of Tor will be almost impossible to disprove, that basically everyone using it is doing something illegal and thus running a node makes you an accomplice, and using Tor is probable cause for the government to come and search your stuff.

If that argument has not already been made in court you know it is only a matter of time before it is.

They make no mention of having been clearly non-responsive to the FOI request. The FOI asked for "Acquisition documents" that they hadn't got one yet doesn't get them out from having been trying to get one. And the excuse of "well we didn't know what the other department was doing" fails, the whole point of a FOI request is for them to find out of someone has the documents in any of their departments. The real problem is that these FOI laws lack meaningful penalties for failure to properly respond so no one ever does.

You can't prove a negative

It's called proof by contradiction.

No you have it backwards, proof by contradiction is a method of showing something is true by showing that if it were false it would be a contradiction with something known to be true. An example in this case would be to say,

"assume there are purple unicorns, that would imply through a chain of logic that there can not be pink spotted elephants, since we know that pink spotted elephants do exist then purple unicorns can not exist, QED"

since you are likely to have difficulty finding a contradiction that results by assuming that purple unicorns do exist this method of proof it unlikely to helpful in this case.

The illegibility that you find so shocking would seem to come from the terminal the poster is using (based on their previous comments) the content would seem to come from the fact that all they appear to want to do is assert that various political view points are bad along with those who hold them regardless of how relevant it might be to the discussion at hand.
