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. 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: Using a debugging tool, Printlining --- Making a temporary modification to the program, typically adding lines that print information out, and Logging --- Creating a permanent window into the programs execution in the form of a log. Some beginners fear debugging when it requires modifying code. How to Understand Performance Problems

Twitter is one of the most popular social networks for businesses, and it gives you an advantage that you may never have had before. Because so much Twitter data is public, you can easily use that data to learn so much about your competitor’s followers and strategies. In this post, we will look at seven ways you can use this data to look behind the scenes of what your competitors are doing. Before We Get Started If you are not already using a Twitter management client, I would suggest you try one. For these examples, I am going to use my Twitter management client, HootSuite, as you can do everything discussed using a free account. 1. One of the best ways to get to know what is working for a competitor is to watch what they do. You don’t even have to directly follow them. In the above example, I am following two accounts from Best Buy. 2. Why watch just one side of the conversation? The lesson? 3. Well, now you can. 4. 5. 6. 7.
Google HTML/CSS Style Guide Strictly keep structure (markup), presentation (styling), and behavior (scripting) apart, and try to keep the interaction between the three to an absolute minimum. That is, make sure documents and templates contain only HTML and HTML that is solely serving structural purposes. Move everything presentational into style sheets, and everything behavioral into scripts. In addition, keep the contact area as small as possible by linking as few style sheets and scripts as possible from documents and templates. Separating structure from presentation from behavior is important for maintenance reasons. It is always more expensive to change HTML documents and templates than it is to update style sheets and scripts. <! <!
