recommended to find a full-time go development work. Of course, it is more prudent to use go to write something and accomplish some tasks directly in the current position. The most important thing is to apply this technology to practice and to generate value. The main need to pay attention to the design and writing procedures, Java is too oo, so Java programmers are easy to fall into OO thinking, in fact, in addition to OO there are other excellent programming ideas. BTW, I was from Java t

In the early ADT version, there was a bug in which the RAM value must contain "MB", such as "512MB" instead of "512", otherwise the above error message is indicated.It has also been mentioned that the resolution is one of the reasons, but I have not actually encountered, if only to change the

or a view of CPU usage? I went to multicore programming and wanted to see the difference between multicore programming and single core CPU performance ...Cpuz's official website has a tool that can get CPU usage through counters inside the CPU. In addition, you can visually obtain the program's speedup by comparing the execution time of the program. Note that the diagram in Windows Task Manager is unreliable, primarily because multiprocessor environments are complex, such as a dual-core process
