Learn to Program, by Chris Pine A Place to Start for the Future Programmer I guess this all began back in 2002. I was thinking about teaching programming, and what a great language Ruby would be for learning how to program. Unfortunately, there wasn't much Ruby documentation geared for newbies at the time. And it wasn't very good. What saved me was that I made it really easy for people to contact me, and I always tried to help people when they got stuck. A couple of years later, it was getting pretty good. :-) So good, in fact, that I was ready to pronounce it finished, and move on to something else. It took me another year, but now I think it's really good, mostly because of the hundreds of brave souls who have helped me write it. What's here on this site is the original tutorial, more or less unchanged since 2004. Thoughts For Teachers There were a few guiding principles that I tried to stick to. Another principle I've kept in mind is to teach only one way to do something. About the Original Tutorial Acknowledgements
What Would Happen If You Shot a Gun In Space? | Can Guns Fire In Space? | Can I Shoot a Gun in Space? Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required. The only difference between pulling the trigger on Earth and in space is the shape of the resulting smoke trail. The possibility of gunfire in space allows for all kinds of absurd scenarios. Shooting stars Imagine you're floating freely in the vacuum between galaxies — just you, your gun and a single bullet. If you do the latter, Newton's third law dictates that the force exerted on the bullet will impart an equal and opposite force on the gun, and, because you're holding the gun, you. Once shot, the bullet will keep going, quite literally, forever. Getting down to details, the universe expands at a rate of 73 kilometers per second per megaparsec (about 3 million light-years, or the average distance between galaxies).

Disturbing Simple Facts and Errors in the BP and Oil Commission Reports Disturbing Facts and Errors in the BP and Oil Commission Reports A Preliminary Review of BP’s and Oil Commission’s Reports- Some Disturbing Simple Facts or Errors (References) on Depths We are compelled to ask how there can be so many disturbing facts (inconsistent) and simple errors in both the BP and Oil Commission Reports? Simply put, there are now many more new questions and concerns given the data and information that has been officially published. The following cursory assessment presents a “report on the Reports” submitted to the Gulf Oil Spill Remediation Conference by BK LIM, Geohazards Specialist. We leave it to the reader to decide how to interpret the various basic discrepancies.

There are really wonderful sources to start learning these new languages, understanding the concept behind programming and giving it a try with some interesting problems. Basic Programming Via XKCD To learn a new programming language, it’s much easier if you already know the concepts because you can start learning the new structures in no time. Programming Concepts : This is a brief tutorial for new programmers from the City University of New York. Learning a Language Whether you already know some programming languages or you are moving forward, you should choose a language to work with. Learning HTML Via Cyanide and Happiness HTML is quite a simple language that doesn't use variables or operations. Learning Python
