Programming is a high-risk job
August 22, 2017 at 12:34

Programming is a work with high work intensity, high concentration, and high risk. High risk, first, because the task originally planned to be completed within about 3 hours, may actually take 5 to 10 times, or may be completed ahead of time, the time is completely unpredictable; second, development is very uncomfortable, need to grit your teeth and persevere, survive the hardest part, and do complex coordination, mathematical operations, and a lot of debugging every day.

But the benefits of programming are that you always have the functions you need, and when you're done, a machine is born. More than 90% of programming is mathematical, and the finished product can achieve many incredible functions. Most functions can be implemented as long as there are ideas and requirements.

PHP PK Shell
August 19, 2017 at 12:37

Recently there was an important file management project required Shell + PHP, which were completely different platforms, but could be called from each other to achieve the required functions. The syntax of PHP is succinct and easy to read. When you need to judge whether a process exists in the system, you must use the shell command to program. PHP does not have such this permission.

Both of them have their own advantages and disadvantages. Shell is a built-in command of the Linux operating system. It has higher permissions and can directly implement many system-level functions, but the debugging is cumbersome and the syntax is not easy to read. I preferred to give more functions to PHP to implement.
