mixed emotions

As we all know, the system automatically generates a swift.h file when Swift and objective-c are mixed. Not the bridge file, which was used to import the Objective-c class into Swift, said to be used to guide Swift in Objective-c. At that time on my own computer run no problem, git upload after someone else update alive hint Xxx-swift.h file not found. We all know now that Swift has just come out, is a pit, at that time was afraid of Swift has any spe

In many ways we use the powerful mathematical computing power of MATLAB, while the Java language is the most used programming language today. Now Android is also implemented using the Java language.I've done a few steps on how to do mixed programming.The first step: Of course, the installation of the MATLAB program and JDK, I use the MATLAB version is r2013a, JDK is version 1.7, while using the Eclipse development tools as a Java development tool.Step

Because of the project, node. JS has recently been used to take a restful interface.Performance is good, feel faster than spring boot and the like. And in addition to good performance, as long as the program structure is well organized, do not let too many callbacks to confuse the program structure, overall development efficiency is much faster than Java.Using C + + to optimize some of the modules is a good choice if you want to improve efficiency further. In particular, Nodejs's support for

I have not learned the compilation, the specific principle can look at other people analysis: http://blog.csdn.net/thanklife/article/details/7362893)because extern "C" can always be C + + on the function name, variable name and other symbols name reorganization, so the compiled C target file and C + + target file variables, function names and other symbols are the same (otherwise not the same, for reasons mentioned in the previous paragraph), The linker can reliably link two types of target fil

In general, after using the table in Word, the space between the left and right sides of the table can not be entered text, that is, the text and the table can not achieve the mixed row, because the table completely occupied the table range of all the lines, so that the text has moved to the bottom! As shown in Figure one, There is no place on either side of the table that surrounds the text. So, can we get the form to be

When you make a website with ASP, you often encounter the case that you want to intercept the string. The Len function in ASP, whether in Chinese characters or English characters, is calculated by one unit, because the width of a Chinese character is twice times the width of an English character, in the case of mixed Chinese and English, the actual width of the string is not calculated. If you intercept a string by the length calculated by the Len fun
