The Redis docker page says that it is “an open-source, networked, in-memory, key-value data store with optional durability.” This description captures the key (nice unintentional pun) features of Redis.
Open source — Anyone can inspect Redis’ code or contribute to the project.
Networked— Redis uses the client-server model, in which communication between clients and servers happens over a network. In this…
I arrived in the United States (U.S.) several years ago to pursue an undergraduate education as an international student . There is a lot I could say about the international student experience in the U.S., but the purpose of the short post is to share some of the resources I have found helpful for keeping me informed about relevant immigration policies and filing procedures.
When I talk about my experience as an international student, I sometimes mention that in addition to the formal education I received, I also received an informal one in U.S. …
Microsoft’s releases of the Windows Subsystem for Linux (WSL) and Windows Terminal were causes for much excitement as they signified Microsoft’s commitment to improving the developer experience on Windows. There is still much to be desired from both products, but they have already significantly improved the developer experience on Windows.
One of the issues I have with Windows Terminal is the annoying sound that gets triggered when I hit a text or navigation boundary using the tab, backspace, or arrow keys. Apparently, that sound is a bell, and it is left on by default. …
There is an outstanding issue regarding dependency resolution when both boto3 and s3fs are specified as dependencies in a project. See this GitHub issue if you’re interested in the details.
This is still an issue as of 2021–02–19.
This function comes in handy when there are one or more possible values that could be assigned to a variable or used in a given situation and there is a known preference for which value among the options should be selected for use if it’s available.
If you have been writing SQL queries of at least a moderate complexity, the purpose of a
coalesce function may already be clear to you. But for those who are unfamiliar with it, a motivating example may be instructive.

As a coder, tinkerer, and a proponent of Free and Open Source software (FOSS), I’ve been partial to Linux operating systems for almost as long as I’ve been intrigued by computers.
And while I’m still partial to Linux systems and use one everyday for work, I can’t ignore some of the things Microsoft has done in recent years to make people like me feel a bit more at home in Windows.
In a previous Haskell video, Exploring Binary Trees (Part 2), we implemented three useful functions for extracting values from a Binary Tree into a list. We implemented these functions using the preorder, inorder, and postorder traversal strategies.
If you are not familiar with these strategies for traversing binary trees, I highly encourage you to watch the Exploring Binary Trees (Part 2) video before continuing with this one.
This is a braata video. And if you don’t know what that means, it just means its a little supm supm extra.
In the comments section for the Exploring Binary Trees (Part 2)…
Before we dive in, let us define some key terms that are typically used interchangeably, but are important to distinguish in the coming discussion.
Database — an organized collection of logically related data arranged for ease and speed of retrieval .
Database management system (DBMS) — “a software system that is used to create, maintain, and provide controlled access to user databases” .
In 1970, a computer scientist named E. F. Codd blessed the world with the relational model, an idea rooted in the mathematics of relational algebra that gave us the now popular view of data organized as tables…
The recursive algorithm for reversing a linked list can be very unintuitive for a lot of people. In this article, we will gradually build our intuition about this algorithm in the sections that follow.
Before discussing the recursive algorithm, it’s important for us to understand why we are able to use recursion in the first place.
Here’s the big idea. The linked list is a recursive data structure, which means we can use recursive functions to query or perform operations on it.
We can use recursive functions to query or perform operations on recursive data structures.
Typically, we learn that…
