Here is a digital reconstruction of the city of ruins in 1945: http://www.youtube.com/watch?v=FXD51CY8DkA
Google Earth historical imagery also has aerial photos of Warsaw from '30s, 1945 and present.
If you have a parallel port, an adapter is trivial to build for old joysticks using only passive components.
There are Linux drivers for such adapters. I guess there are drivers for Windows aswell.
A Windows driver exists, you can find it if you google ppjoy (parallel port joystick).
For the EU soccer fans, attent a US sports event once and make it clear you are a foreinger, the Americans will welcome the newbie and show you everything, just remmeber that they like to play pranks and so will offer you a drink of cooled piss and pretend it is beer. Just smile politely and drop it somewhere. It is all part of the experience.
Write a program that tries to help to solve one of your everyday problems. It mustn't be the best in general, but it should be as good and as well suited for your own needs as possible.
It could be something for you personal finance tracking, something for entertainment, a better interface for data that you can download from the web (dictionary? thesaurus?).
The most important thing is that the problem must be interesting enough for you to finish the task so you should be able to at least get the software to a certain level of usability.
Then write documentation for it.
Education, like medical care or any other service, is not a right.
In Europe, specifically my country, part of EU - it is a right. It is government's obligation not only to provide education for each child under 16, but also to ensure that no child is denied such education.
Let me put it this way. Have you seen the Berlin Wall? I have. In some places there were actually two walls, with a no-man's land in between. In that space were machine-gun towers, spaced so close that the guards could kill each other.
And people were willing to sprint through a machine-gun killing ground, just to escape from communism.
I have lived on the other side of the wall. It wasn't so bad and, to stay on topic, health care was quite good and universal. Very important for societies growing from the ruins of WWII. The reasons for people sprinting through the killing ground in Berlin were much more complex than just communism. (Which hasn't been implemented anywhere in the pre-1989 socialist states of Europe anyway).
i.e. if a boolean poll has 49% for one side (9) the other answer has to be 51% (1) The last digits (1 and 9) are completely dependent.
He could just as well pick the lowest number of the two and check distribution of 0-5 digits. I have a bigger problem with his analysis, from TFA:
I did not include "non-response responses" like "other" or "undecided", nor did I include a tally for third-party candidates in races beteween the two major parties.
Given the dependence between the possible outcomes of the poll, I'm more curious about results with this data included.
I'll concede the numerical distributions where base 10 is important, e.g. your $10K tax cutoff, are not going to obey Benford's law.
If there are artificial constrains to the data, like $10K cutoff or some maximum level, the Benford's law is not the right tool.
For example there is no point in applying that method to prices of single products. There are many goods at level x.99â. However, you could apply the Benford's law to the turnover.
very clever how hey grab info using a laser pointer and measuring the vibrations. i'm afraid you might notice the big red dot on your computer though. sienfield flash backs.
You might not notice if they move from proof of concept with laser pointer to a real device. Are you able to see infrared?
Sauerkraut is best not cooked, there are however dishes like Polish http://en.wikipedia.org/wiki/Bigos where cooking brings something new to the flavour.
It seems that admins are recently too happy with removing information from wiki, than adding it.
Mathematical proofs are as much important and informative as their theorems. The proof allows for better understanding of the theorem, you can see why there are certain assumptions in the theorem and what is broken when these assumptions are not met. For some applications the proof is a blueprint for algorithm to solve problem stated in the theorem.
But I guess that biographies of fictional characters and detailed descriptions of Japanese cartoon episodes have much more important place on wikipedia.
I have been working in agricultural market research company. We were receiving data from studies all over the world and had to do some data mining on them. Some quite advanced statistical methods were used so at one point we had to start organizing seminars for our clients. That was very rewarding for a math guy - I could do some math work and teach with decent salary.
I have to use Excel at work for presentation because we need dynamic charts based on pivot tables. For inspiration I recommend these pages. Most of these methods show ways around Excel limitations and twisted paths to display your data right.
For paper presentation I'd go with gnuplot. It requires some work to get it right, but results are impressive and can be easily embedded in LaTeX environment.
As for TFA, I would think that with a programming language and graphics library we would be able to see some more information on a chart. Like the bottom one.
While metric was designed for science, imperial was designed for "normal" use. While metric designates zero degrees and 100 degrees the freezing and boiling points of water, imperial ties them to a reasonable estimate for the coldest and warmest days in a temperate climate zone. Having a basic unit of measurement between a cm and a m (ie a foot) seems nicely convenient for measuring things at the size of an average human work product, given the size of our hands, feet, etc
The argument that imperial is better for daily use is repeated here over and over. However I have been using metric system all my life and it is intuitive for me that where I live there is at least 30C in hot summer, about 20C in spring and 0C to -15C in winter (except January 2007). I can easily estimate dimensions of things in cm by looking at them, their weight in kg by trying to pick them up etc. I know how 500ml of beer will affect me and what will happen after four shots of 100g vodka glasses (or 8 x 50g, both are common).
There is nothing special about imperial or metric system for daily use. You just have to be accustomed to it.
A unit between cm and m exists: 1dm = 10cm = 0.1m, but is rarely used (at least here).
Yes, they follow the law. Otherwise they face fines (companies) and jail (people responsible for personal data security or lack of it).
I have worked in one of European national telecoms, I had access to full personal data of millions of our clients. Our computers were locked down so we couldn't copy the data on floppy/cd/usb. The network was tightly separated from the rest of the company intranet not to mention the Internet. Our office was monitored.
Before even touching the keyboard for the first time we had two full days of lectures about the relevant personal data protection bill, internal company rules, how to behave in case of security breach and so on.
Yes, personal data security is taken very seriously here. It always amazes me why with you don't have similar set of laws in the US.
Point being, the sqrt(2) problem requires logic to solve, but it also requires significant education to be able to solve
Education is required to know what is the difference between rational and irrational numbers. From this point it is only logic. The proof starts with question: "what would happen if sqrt(2) was rational?" and follows with consequences. It is an excercise in logic.
There are no data write pins on IDE cables. Removing WR pin (data direction) would prevent the host from sending any commands to the device - including 'identify' and 'read sector'.
Always rounding up, which is what US kids are taught in school, will eventually create a bias and throw the aggregates off.
Here, in the middle of Europe, I was taught to round like this:
3.4 -> 3
3.50-> 3
3.51-> 4
3.52-> 3 ...
3.6 -> 4
So, if a digit after '5' is even I round down, when it is odd I round up. It can be used the other way round, but just have to be consistent over all calculations. This way the bias is minimized.
Banking accounting programmers should already know that you can't store and calculate on decimal fractions accurately using binary floating point numbers. It's not a big deal to write a decimal arithmetic class on your own, but first - you have to be aware of the problem.

...what are the Bennett Hasleton's thoughts on that matter.

Dear God, this is so true.
Why is coalition government called "risk"? It's quite common in continental Europe and in European Parliament too. What is the problem here?

Spying and betrayal is not as black or white case as most readers here would want. Consider two biographies:
http://en.wikipedia.org/wiki/Ryszard_Kuklinski
and
http://en.wikipedia.org/wiki/Marian_Zacharski
How do you think? Which one was a hero and which one was a traitor. Both of them? Neither?
(or in another words - applied math)

You propose rational not real numbers. It's been done before.

However creating a real number object is interesting thought excercise, considering how reals are constructed from rational numbers, like Cauchy sequences: http://en.wikipedia.org/wiki/Construction_of_real
Probably not practical.
