Episode 21 - Maps, Hash Maps, Tree Maps, and Hash Tables
Today in less than 20 minutes, we'll explore what maps are and how they work under the hood. We'll talk about the differences between treemaps, hash maps, and hash tables. We'll dig pretty in-depth...By the end of the episode, you'll understand how to implement hash tables using an array, hash function, and a linked list!

Episode 20 - Static and Dynamic Systems
Today we'll look into static and dynamic systems. We'll discuss what does it mean for a programming language or a framework to be static or dynamic. In the second part of the podcast, we'll focus on some of the properties of static systems and how they can help in better compile-time optimizations, development experience, and more!

Episode 19 - Type Systems and Type Checking
In this episode, we'll look at the very basics of type systems and their enforcement. We'll discuss strongly and weakly typed languages. After that, we'll dig into different enforcement strategies - runtime with dynamic typing and compile-time with static typing.

Episode 10 - Topological Sort
The chances are that the information from this episode will come in handy to you during a coding interview and likely in real life! In this episode, you'll learn the topological sort algorithm. Along the way, you'll understand what's a dependency graph and how topological sort operates on this data structure. We'll also discuss a few real-life examples where I had to implement topological sort myself!

Episode 9 - Sorting. Counting Sort.
Have you ever been frustrated during interviews thinking that your interviewer expects you to have memorized a bunch of sorting algorithms you'd never need in real life? In this episode of the podcast learn how to approach such situations. In performance critical systems you may have to implement an efficient sorting yourself. Learn how to beat the built-in algorithm in a few lines of code!

Episode 8 - Decorator Pattern
Today you'll learn how at runtime, you can enhance the behavior or existing objects using the decorator pattern. In this episode, we'll discuss the advantages of decorators over inheritance and look at two examples from real-life - implementing a network communication protocol and enriching user interface components.
11 minutes | Feb 11, 2020
Episode 7 - Tries
In the episode today, we'll talk about the trie data structure. You'll learn what tries are, how you can use them in practice, and how to implement them in your favorite programming language!
