O\'Reilly is celebrating the release of Java 7, and our inaugural OSCON Java conference: July 25-27 in Portland, Ore. Java\'s open source ecosystem is strong and healthy, one of the primary reasons for our creation of OSCON Java. Over the last decade, several projects have traveled beyond mere adoption and had effects dominating the Java world, into software development in general, and some even further into the daily lives of users. JUnitPorted to Java by Kent Beck and Erich Gamma from Beck\'s work in unit testing in Smalltalk, JUnit has been largely responsible for popularizing test-driven d...

Usually if you see on your website a white/blank space instead of Adsense ads, this means that Adsense cannot show adds in that unit for some reasons (we are going to talk about possible reasons below) and also you have enabled the “Fill space with a solid color” feature (in the “Choose what to display if no relevant ads are available” settings of this ad unit). I probably should also say that if you set “Show public service ads” instead of the “Fill space with a solid color” one, the PSA will be shown instead of a blank space.If you notice no us...

If you are a student, you probably know C, C++ and Java. A few know VB, or C# / .NET. At some point you’ve probably built some web pages, so you know HTML, CSS and maybe JavaScript. By and large, it is difficult to find students who have any exposure to languages beyond this. And this is a shame because there are a number of programming languages out there which will make you a better programmer.In this article, we give some reasons why you must learn Python or Ruby2.Compared to C/C++/Java – Python/Ruby allow you to write the same program with much, much fewer lines of code. It i...

When it comes to hiring practices, the tables have turned – capsized, actually. After a global recession saw thousands of jobs lost in IT departments everywhere, now the race is on to hire swarms of top talent. The trouble is: There isn’t enough talent to go around, and the threat of losing key staff to “poachers” is growing daily.“In the current war for talent in Silicon Valley, a lot of leaders believe that it is not possible to compete with the Google and Facebook phenomena and take it as a given that they will lose key team members to these giants,” sa...

Next are some tips for writing highly efficient PHP codes. They are described below:0. Use single quote to replace double quote, this will be better since PHP will serach for variables in double quoted strings. Note, only echo can do this;1. If we can define methods of a class as static, then do it. It will increase access speed by 4 times;2. $row["id"] is 7 times faster than $row[id];3. echo is faster than print, and also use echo's multiple parameter format such as echo $str1,$str2 instead of echo $str1.$str2;4. When using for loop, make sure the maximum number of executions instead of calcu...

This article describes the steps to create a custom PHP extension DLL for the Windows platform. The Zend API documentation that comes with PHP 5 on Windows (see php_manual_en.chm) does a good job explaining how to write extension methods, parse method parameters, and return values. But there is not currently a good step-by-step tutorial on how to get your first extension project up and running on Windows. The aim of this article is to fill that gap.PrerequisitesVisual Studio 2005You can alternately use the free Visual C++ Express Edition or the VC++ 8 compiler in the Windows SDK v6.0 if youâ�...
