Requests (https://github.com/kennethreitz/requests) is a popular http request handling package. Its code is supposed to be well written and pythonic. So I decided to learn from it and improve my Python programming. Here is something that I learned or re-learned.

Simple, access files with the same IO patterns but different languages (C++, Python) and see the difference.

I have had gas problem for quite a while. Usually, right after I have lunch, gas starts to accumulate in my belly. Then comes the fart. It was really annoying, especially when you sat in the front row of a class. Sometimes it was even painful as there are too much gas in the belly that somehow couldn’t get out.

The goal is simple. During my research, I often need to run a lot of different workloads, plot the results and write some analysis text. My goal is to:

• find out parameters I used to generate the results. So I can answer questions “why I see an outlier in my figure?”
• find out the script that I used to generate the plot. So I can improve the figure for publication.
• rerun the whole program and get the results. So I can produce new results by changing the old one.

In Fall 2013 semeter, I read about 100 papers, for 2 courses and research. In the winter of 2013, I read some more papers for my PhD qualifying exam. That was very intensive. Here are some updates about reading papers (for qualifying exam, for details):

There are some tutorials on the Internet. However, they are not up-to-date. Currently Minix has the latest version 3.1.8. It has some changes, say a virtual file system. So a  newer tutorial is necessary. This article also includes a part for adding system calls to servers that are not visible to users. For example, users cannot call the functions in MFS directly because there is a middleware layer, VFS, between them. In order to call some function in MFS, one need to add a system call to MFS and then call it from VFS. The steps of adding system calls to MFS is slightly different.
