This gist started with a collection of resources I was maintaining on stream data processing — also known as distributed logs, data pipelines, event sourcing, CQRS, and other names.
Over time the set of resources grew quite large and I received some interest in a more guided, opinionated path for learning about stream data processing. So I added the reading list.
Please send me feedback!
| 用python写一个将中缀表达式转换为逆波兰表达式的程序，并用unittest模块为它配上单元测试 | |
| ## Notes: | |
| ## Version 1: I submitted solution failed last time. And copied my local code again into this box. (Called Huang Xiaomao already. :-)) | |
| ## Version 2: Add code to handle operators * and /, which with high priority. | |
| ## Version 3: Add code to handle parentheses. (Test Failed) | |
| ## Version 4: Fix test failure about handling parentheses, add test case. (Failed to submit code agian, so copied the local code. ) | |
| ## Version 5: #TODO: Do refactor about logic, and code paths. (Too busy on current working staff, will not do this any more. :-)) | |
| #!/usr/bin/python |

Locate the section for your github remote in the .git/config file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
| f = open('jobs.txt', 'r') | |
| num = int(f.readline().strip()) | |
| jobs = [] | |
| for l in f: | |
| l = l.strip().split() | |
| jobs.append((long(l[0]), long(l[1]))) | |
| jobs.sort(key=lambda x:x[0]) | |
| def keyfun1(a, b): | |
| val1 = a[0] - a[1] |
