follow the tutorial exercises. When I really started to write programs, even if it was a small problem, such as storing data, I had to spend a lot of time to fully understand.But I have a lot of time, because I was on the summer vacation, and nothing else to do.What would you do if you had to ask for help and ask questions?Usually I use Google search. But because I'm still a novice, it's going to take me a lot of time. The best option is to go to Stack Overflow. If stack overflow still doesn't

directly with the interpreter that you have implemented. That's what Pyston did before he introduced Libpypa. There is another way of thinking that directly implements a Python bytecode interpreter, the parse. pyc file is available. What you need to know then is the Python object model (for example, how a Python object is represented in memory). If it is the C language to achieve it is probably "everythin

". Anything that happens more than three times means you're wasting your time.It is important to stop planning at a specific point in time, start coding, and then see where your plan needs to be adjusted accordingly. That, by the way, is one of the reasons why I became a fan of agile methods. The best developers I know will be willing to give up their plans when they are no longer appropriate or if they find their plans flawed.HTML5 Technical Personne

What do you need to know about BroadcastReceiver? I spoke about the Service of one of the four major components a few days ago. Today I want to talk about its brother BroadcastReceiver. I am quite entangled in writing this article, because the broadcast receiver is indeed relatively simple, but you should not think that it is simple and will not be connotation. Maybe we will discuss it one more day. In prac

incrementing a local variable.21. Incrementing an undefined local variable is 9 to 10 times times slower than incrementing a pre-defined local variable.22. Defining only a local variable without calling it in the function also slows down the speed (which is equivalent to incrementing a local variable). PHP will probably check to see if there are global variables.23. The method invocation appears to be independent of the number of methods defined in the class, because I added 10 methods before a

all, unless you create a hash-based algorithm yourself.An alternative approach: SHA1You may know that the cryptographic hash code SHA1 is sometimes used to identify objects (for example, Git does this). Is it not safe? No. SHA1 uses a 160-bit key, which makes the conflict almost impossible. Even if there are many objects, the odds of a collision in this space are much lower than a meteor hitting the computer you are executing the program on. This art
