In a way, most new algorithms either solved a previously unsolved problem or improved efficiency (in terms of memory overhead, speed, or other characteristics) of the previous solution. This is the fundamental cycle of scientific research. The binary tree data structure sped up database lookups significantly. Later B-Trees did the same thing. Dijkstra’s algorithm sped … Read more
Do you know the following problem: you know you should write cleaner code—but you don’t actually do it. My biggest struggle with Python so far is building good habits. Examples: To build an object model when it is warranted instead of trying to run functional code. Start with comments. Learn to use automatic testing. Niklas … Read more

A programmer who only works on algorithms is a rare beast in the wild. For some, it sounds like a dream job — others would never touch a job with such a description. However, there are some jobs that involve lots of algorithmic design: Computer science researcher. When working as a computer science researcher in … Read more
My freelancer course member Pratyush wants to improve learning efficiency in Python. He asked me the question: “how can I accelerate the pace of my problem-solving mind?” Focus first and foremost on reading and writing massive amounts of code. It’s that simple. Maximize the time you are looking at source code, and improvement will come … Read more
