Let me preface this post by saying I suck at recursion. But it never stopped me from trying to master it. Here is my latest (successful) attempt at an algorithm that required recursion. Background: You can safely skip this section if you’re not interested in the back story behind why I decided to code this up. I was listening to KhanAcademy videos on probability. I was particularly intrigued by the combinatorics video....
I did a presentation at our local Python User Group meeting tonight. It was well received, but shorter than I had expected. I should’ve added a lot more code examples. We talked about usage of cProfile, pstats, runsnakerun and timeit. Here are the slides from the presentations: Download profiling.pdf The slides were done using latex-beamer, but I wrote the slides in reStructuredText and used rst2beamer to create the tex file which was then converted to pdf using pdflatex....
I decided to try my hand at the Stanford’s AI Class. The pre-requisites mentioned Probability and Linear Algebra. So I started watching Probability videos on KhanAcademy. Sal Khan was teaching how to find the probability of 2 heads when you toss a coin 5 times. A classic nCk problem: The probability of getting 2 heads while tossing a coin 5 times is: But I wanted to find out the probability of getting at least 2 heads when I toss 5 coins....
When was the last time I vented about C++? The answer for that is always: “TOO LONG AGO”. The initial friction to setup a substantial project using C++ is unfucking bearable. When we started code revamp at work recently, I decided to be a good citizen and decided to incorporate cpptest, a unit testing framework in our project. It made me realize how unreasonably complicated Makefiles can be. After 3 hours of peeling away at the complexity I managed to add cpptest to the build dependency of the project....
I was recently assigned to a new project at work. Like any good software engineer I started writing the pseudocode for the modules. We use C++ at work to write our programs. I quickly realized it’s not easy to translate programming ideas to English statements without a syntactic structure. When I was whining about it to Vijay, he told me to try prototyping it in Python instead of writing pseudocode. Intrigued by this, I decided to write a prototype in Python to test how various modules will come together....
