LearningLog is the tag that I use to describe the posts about what I have learned in my self study. I will create this kind of post when I am studying new things and what to write some information down for later reference. The information may be what I have learned or questions that I haven’t known the answer yet or some observations I find interesting. The posts will not be in a tone of tutorial. Because it is about self studying so the accuracy of the hard details in the post depends on what I have learned so far. The details can be not very accurate and I may come back and corrected them later.
