coding1: log query
coding2: buffer write, follow up: what happen if multithread write same file
experience: 會問你一個你工作過的一個系統，要選一個複雜的系統，不要用太簡單的，我用了一個read only service with cache, 他們覺得太簡單。

為什麼要RESTful，為什麼不用web socket等等,不要直接跳進去用一個tool/technology

follow up multi threading, 你可以說要加 lock = threading.Lock(), with lock:

谢谢楼主！给你加米了！

楼主能详细说一下coding 2 buffer write的题目要求吗？

楼主能详细说一下coding 2 buffer write的题目要求吗？

1. # Assume we have a File class whose constructor takes a filepath string as an argument. It has a single method called write, which persists bytes directly to disk.
   
2. 
   
3. # f = File('/tmp/my/file.txt')
   
4. # f.write(b"hello world")
   
5. # Write a wrapper class for the file object which allows us to buffer the writes in-memory. The wrapper class, BufferedFile is initialized with a File class object and a buffer size. It has two methods: write and flush. The data should be flushed to disk when the buffer is full, or on demand with a method called flush. All bytes must be stored in the buffer first before being written to disk. The buffer cannot use more memory than the max bytes allowed.
   
6. 
   
7. # Example usage:
   
8. 
   
9. # f = File('/tmp/my/file.txt')
   
10. # buf_size = 1000
    
11. 
    
12. # b = BufferedFile(f, buf_size)
    
13. # b.write(b"hello world")
    
14. # b.flush()
