Introduction In one of the job interviews, I was asked to answer a puzzling question. The question was simple; but yet intriguing and tricky. Here is the question: You are going to play two teams for three rounds in total. You can not play one team twice in a row. You need to alternate. and…

Bus-Factor
What is your bus-factor? Bus-Factor conveys a very important message, however, in a very morbid manner. I admit, there are other ways to emphasize on the same goal, and I have heard a few different explanation of the same topic. But this one stood out, for obvious reasons. The first time that I heard the…
It works! sometimes!
I had an interesting discussion with one of the employees in a sport complex. I am not going to name the sport complex, because I like that center, and this incident is not going to change my mind about going there. At least not yet. There is a device that everyone needs to use in…
To comment, or not to comment, that shouldn’t be even a question!
What’s the story about commenting? Recently, there was a discussion on LinkedIn around comments, again! As usual, it appears that people either fall on the side of comment everything in this code or the side of avoid comments at all costs, even if there is a gun to your head. Moderation?!! any one?!! This is…
Piecewise-Linear Functions: Part II
In Part I (here), we discussed what are Piecewise-Linear Functions (PLFs). In Part II, this document, we are going to discuss how to estimate the coefficients. As it was mentioned in Part I, if we do not need to guarantee the continuity, all you need to do is to just fit a line to each…
Piecewise-Linear Functions: Part I
We are going to divide this document in two parts. The first part, this document, we are going to discuss piecewise linear functions (PLFs) and how to implement one in Python. The second part, Part II, we will discuss how to fit the coefficients, detect the break-points locations, and even optimize the number of the…
Can I Directly Translate A Math Equation To A Code?
If you have answered yes, then you are betting on being lucky. If you are saying: “I always have done so and never had any issue!!!“, well, (1) you are lucky that you never executed your code with numbers that would cause problem, (2) you are using a library that handles these things under the…
Learning SQL
I see a lot of SQL posts in my feed, getting the impression that SQL is making a comeback and becoming a hot topic again. Indeed, SQL could be a very handy language for many systems/projects and if you are in Data Science and/or analytic positions knowing SQL not only doesn’t do any harm, but…
The shepherd who cried wolf!
How do you understand mathematics? I like to connect them to real world situations, real applications, physics, even stories. This helps me not just learning how to use mathematical techniques, but understanding them. Once an undergrad student who was working on classifying some aerial imagery reached out to me for some help. He wanted to…
