occasional emotion

    Before I knew it, it was Thursday night again. This week's work was not too busy, but for me, this week's study plan seemed to be stranded. There was a security loophole in the function that was launched the day before yesterday. Thanks to our testers, who helped me find this problem, and promptly closed the loophole, which saved a lot of losses for the company and made me realize that The development of the trading system must always be sensitive to security, otherwise the loss will be immeasurable.
    But most of the spare time this week was used for fitness. Looking back on the harvest this week, I only have some understanding of the working method and algorithm of the JVM garbage collector, sorting, B-, B+ tree learning has not been implemented (also Because my foundation is not solid enough, it is still difficult to learn these two knowledge points), whether the plan is unreasonable, or my concentration is not enough, it is time to think about it.
     Forget it, there are still three days this week, and on weekends, I still need to go to the library to return the kindle, return books, and borrow a few more books to recharge. In the rest of the time, in addition to fitness, the sorting algorithm must be implemented. The algorithm idea must become your own, the code must be implemented, and you must write the heap sort, quick sort, and merge sort algorithms yourself.
     Going back to work, in another week, the last round of inspection by the central bank will come. I still need to prepare the structure of the database table for my work, as well as the problems that may be encountered during the inspection. I also need to prepare in advance. The security issues in the system also need to be sorted out systematically, and these need to be implemented step by step.
     Going back to life and study, I am tired of work these days. I always feel that the content of my work has not grown up, and I have been filling the holes left by my predecessors, from the unreasonable design to the control of safety issues. The processing of redundant code, the sorting out of business processes, there are still many things that need to be done. Anyway, let's go step by step.
