The purpose of networking is to build mutually beneficial relationships. That is hardly achievable if the only activity one engages in is attending events and exchanging social media contacts with other attendees.

It will be more productive if after introductions, participants discuss shared interests projects they worked on or are working on the challenges they face and how they can overcome them open source projects they (can) contribute to and learn from connecting themselves to people or communities who are interested in what they’re doing The good thing is, one does not have to be at tech events to do these....

In working with collections (lists, queues, maps) of data, you usually have to perform one or more of the following operations on the collection: accessing, searching, appending, inserting, replacing/swapping, deleting and sorting. Binary search is one of the most popular algorithms for searching for a number within a sorted list of numbers. It has a time complexity of O(log N) which means that its ability to find a number in a sorted list is minimally affected by the length of numbers in the list....

I recently developed a practice of using single-letter identifier names in code I write. This practice is quite contrary to my principle for writing clean code. I aim to make readers understand the code I write without thinking too hard. However, I have two points of view to support this practice. identifier is the generic term for variable names and names of constants. I use the term identifier and not variable name because identifier encompasses variable names and constant names....

In November 2023, I was at the API Conf Lagos meetup. One of the speakers, Toni Alaribe, asked members of the audience to signify by show of hands if they write tests for HTTP APIs they build. Myself and a couple of other people raised hands. He asked members of the audience to signify again by show of hands if they write API documentation, update the documentation with the latest changes and also keep a changelog of the changes....

It was a bit challenging for me to understand Flutterwave’s documentation on cross-currency transfers. After discussing with her staff on Slack, I was able to understand how it works. I have put this guide here for anyone who may be going through this challenge.

This article will help you understand what an interface is, irrespective of the programming language that you use. It will also cover the concept of programming to an interface, not an implementation....

How it started I was working on a project recently where I used mongoose-paginate-v2 to retrieve paginated data from the database. I was trying to type my output because I deselected some fields from the documents returned, but I could not do it because the library did not provide that functionality. I had experienced this in a couple of other projects that I was working on. This time, the inability to achieve this got me frustrated....

In a pet project that I worked on recently, one of the requirements was to allow users to submit the URL to their Facebook social media profile. This article describes how I ensured that only Facebook profile URLs were submitted. JavaScript was used but it does not matter as much as the algorithm used; and that algorithm is described here. function validateUrl(url, expectedOrigin) { const urlObject = new URL(url); const originPattern = new RegExp(expectedOrigin....
