Some lesser-known avenues of C++ — C++ compiler adopts several techniques for optimization. One such optimization technique involves eliminating the temporary object created to hold return values. Such a technique is called Return Value Optimization (RVO). Return Value Optimization (RVO) In the RVO technique, the implementation eliminates the copy operation resulting from the return statement. RVO is a part of…

Some lesser-known avenues of C++ — RAII in the context of C++ stands for Resource Acquisition Is Initialization which is a design pattern in C++ that guarantees that the resource is available to any function that may access the object, and prevents leaks. …

Some lesser-known avenues of C++ — This may sound like a utopia but C++ has a type that is suitable for cases when the return value might just not be present. I would be honest here, I didn’t know about this feature and I realize that need to update my C++ knowledge. std::optional was introduced in…

Interview Question @Aeva ft. HackerRank — Aeva is a LiDAR startup by Apple alums, backed by Porsche SE. It recently went public through SPAC. The company boasts to innovate a ‘4D Lidar’ — the first of its kind that can measure speed and distance simultaneously without losing range. A few weeks ago, I was contacted one…

And Why should we use them! — Virtual functions in C++ play an important role in extending the concept of object-oriented programming. One key aspect of object-oriented programming is polymorphism where the same function calls allow to do different kinds of tasks. …

A metric for object matching with an example in Python — In the last few decades, we saw breakthroughs in data collections in every single domain we could possibly think of transportation, retail, finance, bioinformatics, proteomics and genomics, robotics, machine vision, pattern matching, etc. To analyze and organize these data, it is important to define the notion of object or dataset…

Unification of multiple datasets — Manifold alignment is a problem of finding a common latent space where we jointly perform dimensionality reduction on multiple datasets that preserves any correspondence between those datasets. Before we dive into the details of manifold alignment, let’s understand first what is Manifold. What’s Manifold? An n-dimensional manifold is a most general mathematical…

Dan Brown’s masterpiece — Recently, I felt I was missing Dan Brown’s Inferno that I had completed recently. Crisis, WHO, world population, Florence, Venice, Istanbul … no I am missing a vital lexicon: Dante!
