  Do NOT use boolean variable as function parameters

We follow lots of coding styles and coding standards when we do programming, but we may frequently forget one. The forgotten one is that do not use boolean parameter as the function parameters. The reason is it would greatly reduce the readability of the code. Don't believe it? When you read the following code, what does this code mean? widget->repaint(false); Do not repaint? Or what does this mean? After looking at the document, we know that this parameter is whether ...

  My secret Hobby: Applying for jobs

I have a probably unusual habit: I'm applying for jobs as programmer at least once a year. It 's not that I don't have a job, or that I don't like what I do, but since I am self employed and running my own company I have the feeling that I am coming out of touch of what the current job market is like, and so I started to apply for jobs at different companies once in a while.
