I have seen password attacks on all the ports i have sshd on. They port scan, or a least some do. Either way i can't see how this can work without really bad passwords/pass-phrases. As long as the password is not password, i can't see this working at all.
One of the programing sites i frequent was having a large problem with human spammers. The solution was to add a programming question. You have say what the program outputs. Not only did this get rid of the spammers, but it also got rid of the 16 year olds that just finished playing some AAA that demand you teach them how to write such a game before dinner.
You have taken the analogy way to far. On the internet you need packets to come back to your machine. If the sender field is wrong that does not happen and you can't get a connection. Basically is not that easy to spoof ip numbers outside a syn flood or the like.
Thorium can and has been used to make weapons. Just 2, but they worked just fine. They can melt down or otherwise have containment failures just like any other reactor. Thorium is not magic, you bread 233U from it and and burn that, which has pretty similar fission products as 235U. You save a bit on the actinides though. Otherwise there is still decay heat, there is still buckets of radiation, there is still waste.
Liquid sodium is *not* a liquid salt reactor. Liquid sodium reacts explosively with water, and even fairly violently with the water vapor in the air. What could possibly go wrong? As for molten salt reactors, well they are no panacea either. For example the salts are either water soluble (Chlorides) or react with water (Fluorides). You may be able to burn the very long term waste products, but you still have fission products in the waste stream, ditto with Th.
The prototype pebble bed reactor in Germany was complete failure. Not only was there some serious leaks and breaches during operation, but it has also become a decommissioning nightmare. That was without anything going "seriously" wrong. They are not the magic nuclear energy elixir you have been lead to believe they are.
I wouldn't say its the exception. After all it not news when bridges don't fall down, or last longer than expected or [insert positive outcome here]. Its only news when something goes wrong. The bulk of our engineering works fine not only in design conditions, but well in many cases a little "off design".
Software engineers at least in my country are also liable, just like regular engineers. In fact they are regular engineers. Software developers not so much.
Trademark is about if its clear what the consumer is getting. There is no doubt that a web site called Pinbook can be confused with facebook, it is not diluting anything.
The only problem with the 3He is there is hardly any on the moon. Like 2.8ppb. So about 100x less energy dense than coal, and you still need to get the 3He out of the stuff. You would probably end up using more energy getting the 3He than you would get out of it. Now add the fact that if you can burn 3He you can also burn DD, there really is no point at all. The 3He reason to go to the moon was invented my people desperate for a reason to go back.
Which is why i have an Android. I can pick a model that fits what I want. I don't get to pick jack with apple. I wanted a small phone with a few days battery life. I don't want these big phones, the screen is still to small for a lot of reading and battery life is awful. Well i waited till there was a model that fits what i want, that was the galaxy fit, but by the time i got round to getting it, there was the galaxy y. A perfect model for my needs. It was also only 100EU, I get 3 days battery life mostly, and with a 16gig mem card is a pretty good mp3 player. It was perfect for skiing (gps tracking) etc. The much smaller size is great.
As for the android market. Well yea, there is soo much for free and even if there is something in the 1EU range, it is such a pita to register for pay apps. The barrier to entry is that the free ecosystem on android is really good.
This is true. We could use our cell phones in a Faraday cage we built on the 6th floor at a physics department. In the end we used the local "FCC" facility that is underground. It was the only way they could the local background EM noise down to acceptable limits for testing.
Not even close. It wouldn't change the weather at all on the scale of days. The energy needed for a tsunami like the one that hit Japan just short of a year ago requires enormous amounts of energy. The thing is that the earth is really really big, and even though this rock is moving pretty fast, its not that fast, and its not that big. It is comparable to nuclear weapons that have been tested, these did not change weather or produce "significant" tsunami's. At lest not at the scale you are thinking of.
This is quite wrong. The smaller ones are hard to track, but anything big enough to be civilization destroying is much easier to spot. Typical estimates is 5+ years or more warning.
Well one we don't know if exotic matter exists that *can* warp space the way that is needed. There are no particle candidates in the standard model either. The next big problem it that you need more energy than in the entire visible universe. There are a bunch of other problems, like that it does not conserve some things that are widely held to be conserved. etc...
Since number of rare events in a fixed interval is Poisson distributed, or equivalently the time between events is exponentially distributed. Just dividing by 8 is not correct.
Lets use a binomial distribution approximation since it tends to be more intuitive. Let the probability that a flare will happen in a year is p. Also we assume the probably that 2 flare happen in a year is small enough to ignore. Then the probability that no flares happen in 8 years is (1-p)^8. The probability that just one flare happens is p^8. The probability that n flares happen in 8 years is (8 choose n)p^n(1-p)^{8-n-1}. ie a binomial distribution.
If we equate the chance of no flare happening we get (1-p)^8=1-1/8. Hence p=1.65%. At p=1.5% the probably of no flare happening in 8 years is 88.6% or in other words the probability that at least one flare happens in 8 years is 11.4% (compared to 12.5%).
All of it. A geomagnetic storm has zero effect on small things. You need loops of conductors kilometers long before you get any problems. HDD and the like are a bit smaller than that.
Because we are given jobs by big university HR departments. They count up "impact factors" and other BS metrics to measure your output. So publishing elsewhere can be a good way to not get your next job.

What the hell does first to file have to do with obviousness or prior art. Pro tip: Nothing.

You can run the numbers easily enough.
