Course Introduction：What does a day in the life of a programmer look like? After a busy day at the company, I work overtime, come home, lie in bed and play with my mobile phone, and go to bed at twelve o'clock or even later. Days passed like this, and in a few years, technology reached a bottleneck and wages remained unchanged. There is no difference between working for ten years and working for one year. Slowly, my life became something I hated. There are too many such examples around us. I believe that if you live every day according to the above, you will definitely encounter the 35-year-old crisis when you are 35 years old. So how to change and avoid this situation?

How to make API call in created hook in Vue 3?
Returning to vue after a long break. In my solution I'm using composition api and after creating the component I need to get some data so I can display it later. In my current solution, the template is rendered before calling. Probably stupid mistake but I still can't figure it out (it's clear in vue2.0 - create() hook). 2023-11-04 08:48:38 0 2 248 Issues with Vue.js 3 and Pinia Getters 2023-11-03 18:52:56 0 1 244 Connect Visual Studio Code to a remote MySQL database: Simplify the connection process 2023-10-24 20:41:24 0 2 231 Course Introduction：The time it takes for the CPU to fetch an instruction from main memory and execute it is called the instruction cycle, which is often represented by several machine cycles, which in turn includes several clock cycles; the instruction cycle refers to the steps that the CPU goes through to execute the instruction. 2020-02-14
comment 011149 Course Introduction：Data cannot be exchanged directly between the hard disk and the CPU. Reason: The CPU is fast and the external memory is slow. If the CPU is allowed to access the external memory, the CPU will waste a lot of time waiting for the return data from the external memory; and the read and write speed of the memory is much higher than that of the external memory, so the hard disk and other external memory The data in the memory must be transferred to the memory before it can be accessed. 2021-06-24
comment 029202 Course Introduction：本文的目的是在Java进程中确定哪个线程正在占用CPU的时间。当您的系统CPU负载居高不下时，这是一种有用的故障排除技术。下面是详细步骤：1.首先确定进程的ID，可以使用jps-v或者top命令直接查看2.查看该进程中哪个线程占用大量CPU，执行top-H-p[PID]结果如下：可以发现编号为350xx的共有9个线程占用了100%的CPU，好，接下来咱们随便取一个线程ID，假设我们想看编号为35053这个线程。首先将35053转成16进制是88ED（可以用开源中国在线工具转换）3.接下来我们将进 2024-06-07
comment 0215 Course Introduction：There is a cooperative relationship between the CPU memory and the hard disk. The CPU memory is responsible for the data exchange processing between the data on the hard disk and other hardware and the CPU. It has the characteristics of small size, fast speed and electricity storage, while the hard disk is used to store data such as information and software. The equipment has the characteristics of large capacity and no loss of data when power is turned off. 2020-07-27
comment 07834 Course Introduction：PyCharm provides methods to view program running time: Run configuration: enable the "Collect CPU usage and profiling info during execution" option. Profiler: Collect data and click the "Start profiling" and "Stop profiling" buttons. Performance Monitor: Displays metrics such as CPU usage and runtime. timeit module: Import the module and measure runtime using the timeit.timeit() function. 2024-04-18
