How to be a Programmer: A Short, Comprehensive, and Personal Summary
Debugging is the cornerstone of being a programmer. The first meaning of the verb to debug is to remove errors, but the meaning that really matters is to see into the execution of a program by examining it. A programmer that cannot debug effectively is blind. Idealists that think design, or analysis, or complexity theory, or whatnot, are more fundamental are not working programmers. The working programmer does not live in an ideal world. Even if you are perfect, your are surrounded by and must interact with code written by major software companies, organizations like GNU, and your colleagues. Debugging is about the running of programs, not programs themselves. To get visibility into the execution of a program you must be able to execute the code and observe something about it. The common ways of looking into the ‘innards’ of an executing program can be categorized as: Some beginners fear debugging when it requires modifying code.

How To Become A Hacker Copyright © 2001 Eric S. Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker?".

A lot of hackers now consider it definitive, and I suppose that means it is. Still, I don't claim to be the exclusive authority on this topic; if you don't like what you read here, write your own.

How to be a good programmer...My tips (Sandip Dev's blog) This article has been cross posted from my personal blog : At the very onset, let me make it clear that I DO NOT consider myself a good programmer. I rate my coding skills as average and I am still learning and have a long way to go before I am even slightly pleased with my programming skills. Yes I am better than quite a few people when it comes to programming, but thats merely because they are lazy and like to sit on idly all day and never bother about programming. Their horrible skills make my less horrible skills look marvellous. I have performed abysmally in ICPC and have never done well in any coding contest worth mentioning (I DO NOT consider college level contests worth mentioning).

New Programming Jargon Every field comes up with its own jargon, and oftentimes subgroups within a field come up with their own specific words or phrases (those of you familiar with Microsoft Canada’s Developer and Platform Evangelism Team know that we have our own term for “broken”, named after one of our teammates who is notorious for killing all sorts of tech gear). A question recently posted on Stack Overflow asked for people to submit programming terms that they or their team have coined and have come into regular use in their own circles. I took a number of the submissions and compiled them into the alphabetically ordered list below for your education and entertainment. Have you come up with your own jargon? Tell us in the comments!

History of Linux, Who Invented Linux, How Was Linux Invented Who invented Linux? Linux is the first truly free Unix-like operating system. The underlying GNU Project was launched in 1983 by Richard Stallman originally to develop a Unix-compatible operating system called GNU, intended to be entirely free software. Many programs and utilities were contributed by developers around the world, and by 1991 most of the components of the system were ready. Still missing was the kernel. 10 steps to becoming a better programmer Hi and welcome back to my blog!

Data Visualization for Non-Programmers: Impure Impure is a new programming language designed to give non-programmers access to professional tools for data visualization. Users can use it to process and display data from social media feeds, financial information and more.

The history of Linux: how time has shaped the penguin As we sit in front of the latest version of Ubuntu, Fedora or SUSE, revelling in the glorious animated desktops, taking pleasure in the ease-of-use the GUI grants and enjoying the fact that most of our hardware works out of the box, do we ever wonder how on Earth our favourite operating system got to this point?

How to read XML file in Java – (DOM Parser) In this tutorial, we will show you how to read an XML file via DOM XML parser. DOM parser parses the entire XML document and loads it into memory; then models it in a “TREE” structure for easy traversal or manipulation. In short, it turns a XML file into DOM or Tree structure, and you have to traverse a node by node to get what you want.
