Submission + - NSA Can Hack wifi 8 Miles Out - Implications For Commercial Use (ubergizmo.com) 2

littlewink writes: Assume that the NSA, as they claim, can hack wifi 8 mile out. Then it must be possible for a network of enhanced wifi routers (not controlled by the NSA) to act as a wide-area network similar to now-defunct Metricom's Ricochet system except far more robust, distributed and less costly. Such a network, by reducing the role of local ISPs, could reduce unwanted monitoring (by NSA and others).

I am asking for suggestions about software/hardware enhanced stacks for such a "New and Freer Internet"?

Comment Perhaps CA Could Allow Citizens To Be Armed? (Score 1) 396

Oh, but that's recently been banned, hasn't it? I'm fairly certain that all terrorists, just like all good liberals, have duly registered their CA-legal firearms/weapons and turned in their illegal ones to the appropriate authorities. We need not worry about jihadis in California - they're all good law-abiding citizens. Just heard a story on the radio today: soon after Pearl Harbor, analysts feared the Japanese would attack the West coast. Estimates were that the Japanese could not be stopped before reaching the Mississippi River. After the war the Japanese generals were questioned on this. The reason they chose not to invade was that they knew that most Americans a) had firearms and b)knew how to use them.

Comment CFLs A Costly Mistake For This Condo (Score 4, Insightful) 944

I was president of a condo association for 5 years. I made the costly mistake of replacing all outside incandescent lights with CFLs:

- all CFLs, regardless of brand, failed within two years. Outdoors CFLs don't last as long as the cheapest incandescents, despite all caterwauling to the contrary. Please don't tell me about your special brand: I've tried it and it failed prematurely.Please don't tell me to return them to the store under the 3-year guarantee: if I did that all my time/gas would be spent driving to/from Home Depot/Lowe's/Light Store and changing bulbs.

- CFLs were frequently stolen. This was an unanticipated cost.

LEDs are even worse: thieves can spot an LED from 100 yards away and will stop at nothing to steal them (since they're so damn expensive). Great to spend $300 replacing a weatherproof floodlight receptacle and the electrical tubing because a thief tore it off an outside wall to get a $50 LED floodlight.

After 3 years I gave up and went back to incandescents, which we will use forever. Savings due to CFLs low electrical usage are not recovered when you include failure and theft in the equation. In fact, incandescents are cheaper even when you include the cost of the rugged models.

There are good reasons why incandescents have been used for so long. And, as others note, you can heat the chicken coop, keep pipes warm, and do other useful tasks with incandescents. CFLs were a political solution to a non-problem.

Comment Devices w/o Keyboards Are Bandwidth-Limited (Score 2) 453

It isn't possible to type as quickly and accurately on a tablet or iPhone as on a desktop PC. It isn't possible to precisely select a graphical element in one step (as in a CAD drawing).

Since voice input/control is not there yet, we are restricted to using mobile devices' clumsy keyboards. Even with voice, it is likely that users will opt for keyboards for other reasons (privacy, quiet in a group work environment, etc.).

Comment Cheaper Solution: Use Culverts, Culvert Pipe (Score 1) 189

Protect yourself by climbing into the pipe.

It would have to be buried or anchored and topped with earth/asphalt/gravel/concrete to streamline air flow over the pipe.

Normally a culvert pipe is laid horizontally and could hold a number of people. Or you could use short sections and set them in the ground vertically. When trouble comes you climb in with a built-in ladder. Although these would be more trouble to maintain because:

  • - snakes, bugs and rodents would like to live there too,
  • - would be like having giant prairie dog holes in your yard: not very safe unless they had good covers.

Just as in a pinch, an underpass or a culvert pipe is a safe haven in a tornado, so this could cheaply save a group of people. And it wouldn't be as difficult as escape pods for those with claustrophobia.

Comment Wrong Solution - Use individual "Escape Pods"... (Score 1) 189

like in science-fiction movies. I envision a hardened shell, coffin-like (but they could be spherical or any shape really), whose entry is flush with the ground. Each would be anchored or chained at a number of points to galvanized stakes (like fence stakes) driven deep into the ground. When a tornado approaches, you climb into your escape pod and latch it shut until the storm passes. This could be cheap and effective for all but the claustrophobic.

Comment Financial Firms Do Not "implement" NSA Spying (Score 1) 513

"Also the heads of JP Morgan, Citibank, Halliburton, etc, and all the shadowy 1% who are implementing this police state."

There is no evidence that those corporations are willing prticipants, much less "implementors". You're jumping into paranoia with this statement.

I am no friend of those corporations and believe the financial firms should be prosecuted; the NSA data could be used to do this or merely to blackmail them into supporting government policy. So I don't believe that JP Morgan is a willing friend of the NSA.

Comment Violent Non-schizophrenics Are Much More Common (Score 1) 138

To be clear:

1.1% of the population are schizophrenic and 98.8% are not.

Of schizophrenics, the fraction 0.05 (5%) are violent, so the percentage of violent schizophrenics in the total population is

1.1% x 5% = 0.011 x 0.05 = 0.00055 (0.055%) .

Of 98.9% non-schizophrenics, the fraction 0.03 (3%) are violent, so the percentage of violent non-schizophrenics in the total population is

98.9% x 3% = 0.989 x 0.03 = 0.02967 (2.97%).

So there 53 (0.02967/0.00055) times as many violent non-schizophrenics as violent schizophrenics in the total population. That is, in a random encounter you are about 50 times more likely to meet a violent non-schizophrenic than a violent schizophrenic.

Comment 4. They're On The Lam... (Score 1) 629

You forgot a most likely possibility: they are fugitives from their own civilization. They need to get away for awhile to someplace safe and environmentally compatible until the heat is off. They could either plan the trip here or merely stumble across our planet while running away. So the first aliens we meet could be simple criminals.
