Today, you can simply enter 1.6449340668 into Wolfram Alpha, and find pi^2/6 as a suggestion. Cool.
Seems like your personal experiences do not fit your generalizations. Think about it.
Before I forget, there are lots of local people who do not understand or care for democracy, human rights, etc. (In my country, a lot of these guys are also quite anti-american, probably because they believe that America is ruled by the "jews".) Unfortunately, your arguments/anectdotes sound a lot like theirs.
I live in one of those countries, so I can read national news. Even better, I can form my opinion from first hand experience. You may read this stuff in the tabloid press, but that does not make it true. How do you know that "much of the immigration moving in to Europe has no intention of ever integrating"? And let me add something about the riots in Paris: these are not caused by cultural differences, but by largescale unemployment. Think South Central Los Angeles.
Obvious question: what is 95% confidence supposed to mean? How is it different from say 94%?
As long as the student cannot come up with something like "there is a chance of 5 in 100 that the result was caused by the sampling process" he has no idea what he is talking about.
Speaking of critical thinking, the student should also understand that one in twenty results with 95% confidence will be wrong.
Of course seven stones is a lot. Also, this was not a tournament game. But still, this is amazing progress.
Btw, an older version of mogo is freely available, try it out for yourself.
Just some thouhgts:
The paper ballot can be understood and verified by every voter. The technique used may be simple, but the protocol is quite sophisticated.
To verify the system you propose, you would still need to repeat all calculations. Also, how do you verify that the random numbers are really random?
Your argument for stochastic verification suffers from a lack of randomness. The 0.1% percent that actually check will be far from random.
Electronic voting is supposed to make the voting process easier. Manual verification of hashes of several hundred bits is not my idea of simplicity.
Even if this works in theory, there may be flaws in the implementation. And even if implemented correctly, there may be issues with key management.
But most importantly, for 99,9% of the voters, it is impossible to understand the system, let alone verify the actual vote. Therefore, it is just a matter of time (or money) before some manipulation by insiders takes place.
The real problem with electronic voting vs banking comparison is that banking has a completetly different aim: earning money.
Electronic banking is not secure. Period. E.g. in 2008, in the U.K. online banking fraud caused losses in the order of 50 Million Pounds. However, the banks still make a profit. ("It's just the cost of doing business...")
This kind of thinking is a bit problematic with voting.
You obviously have no idea what a context switch is.
A context switch happens when the scheduler stops one process/thread and gives the CPU to a different one. This has nothing to do with cross-library calls.
For those who don't know Der Spiegel, it meant "The Mirror". And to those in the UK, yes, it's the same kind of newspaper.
Huh? Der Spiegel is considered a high quality magazine, if there ever was one. Of course they are a bit politically biased, and yes, they are intellectual snobs. But still, their articles are usually very well backed up by recherche.
Slashdot Mirror
It also means you were very likely using a freeware assembler that used decimal labels. Those were the days...

Maybe so, but stuff like boost multi-index containers is really great.
Yawn. The first time I read this hex joke was about FORTRAN8x.
Oh, and Sweden's quickly climbed to the top of the list of "Places for a Young Muslims to Travel and Find Young Girls to Rape".
much of the immigration moving in to Europe has no intention of ever integrating into the society around them
This is just the kind of unsubstantiated stuff the european far-right parties keep repeating.

Well this is nothing special. E.g. Greece has a similar law.
Who modded this paranoid rant insightful? Any idea what "invasion" means?
Calvin was not a jew, dude.
ah, so that's the other half!

These days are over.
Go program beats professional 9 Dan at 7 stones handicap
On a side note, Zhou Junxun won the LG Cup 2007, so this is definitely a top player.
Maybe I am overlooking something, but what is the point of hashing here? What is the gain compared with simply handing out a random number?
Assuming the number is not random or can be stored, the hash will not prevent a dictionary attack.
Great idea, send your secret random bits to some web app for harvesting

Moore's law isn't exatly as reliable as it was 15 years ago when talking about a direct improvement to the desktop computers speed.
Since Moore's Law is about Transistor density and says nothing about speed, I see no difference in reliability.
... but bad programming habits prevail ...
as promptly demonstrated by the following rant:
PLEASE! What could be more fundamental than screening out acquired text data for illegal characters and lengths?!
Answer: usage of prepared statements.
And while we are at it, let us not forget to mention Qt.
