Hackety Hack! Computer Programming Basics. A computer program is nothing but a set of instructions, which when executed, give results to a certain operation.

Computer Programming Basics

These instructions need to be written logically, i.e, they should be in a flow, and before writing the program, you need to decide the flow of the program. Remember, the computer is a very intelligent machine, but it can do only what you ask it to do. So the program that you are writing will go wrong, only if there is something wrong with its set of instructions. Problems arise in computer programs due to manual errors. Before going into further detail, let us try to understand the different levels of programming languages. Machine-Level Language At root level, a computer works in bits and bytes. Assembly Language An assembly language is just one level above low-level machine language. High-Level Language High-level languages are far simpler to understand than assembly language or machine-level language.

Ruby on Rails Tutorial: Learn Rails by Example book and screencasts by Michael Hartl. Michael Hartl Contents Foreword My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP (Google me to read about the drama).

Ruby on Rails Tutorial: Learn Rails by Example book and screencasts by Michael Hartl

This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on Rails Tutorial is what I used to switch back to Rails again. Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it. The linear narrative is such a great format. Enjoy! Derek Sivers (sivers.org) Founder, CD Baby Acknowledgments The Ruby on Rails Tutorial owes a lot to my previous Rails book, RailsSpace, and hence to my coauthor Aurelius Prochazka. I’d like to acknowledge a long list of Rubyists who have taught and inspired me over the years: David Heinemeier Hansson, Yehuda Katz, Carl Lerche, Jeremy Kemper, Xavier Noria, Ryan Bates, Geoffrey Grosenbach, Peter Cooper, Matt Aimonetti, Gregg Pollack, Wayne E.

About the author Copyright and license 1.1 Introduction. A Unix and Perl Primer for Biologists. Available translations of this page: Belorussian Deutsche Russian Serbian We have written a basic introductory course for biologists to learn the essential aspects of the Perl programming language.

A Unix and Perl Primer for Biologists

This started as a course for grad students at UC Davis, and we then ran it as a one week intensive course for anyone on campus who was interested (sponsored by the UC Davis Genome Center). The feedback from these courses was very positive and so we have decided that we should make it available to anyone who is interested. The course is very much aimed at people with no prior experience in either programming or Unix. It is increasingly common that biologists have to deal with vast amounts of in silico data as part of their research, often in the form of many large text files that are the output from research equipment or computer programs.

To start the course, you first need to download the course material (a set of test files and directories that relates to the documentation). Learn Python - Free Interactive Python Tutorial. Code It Online.
