How to do Coding Peer Reviews with Github

In my current contract, we do coding peer reviews. When I was first introduced to this process, I was a bit sceptical. Mostly, I thought it was a huge time-suck and an overly-laborious way to fix bugs.

After several months of going through the coding peer review process, I can say I’m a convert. Anything that improves the quality of code and simultaneously enables a team of coders to give feedback and learn from each other, is a good thing.

In this video, I go through some of the main benefits of the coding peer review process, as well as demo-ing how to do coding peer reviews with Github.

Biggest Developer Frustrations Reported By You (Q&A)

As part of our weekly monthly newsletter, we send a survey out to all of our readers. A small percentage of our readership respond, but their answers are always telling.

One of the questions we ask is: What is your biggest frustration?

The top 5 answers are:

  1. Not having enough time
  2. Finding work as a developer
  3. Too many technologies to learn / fast-pace of technology
  4. Finding bugs
  5. Coming up with ideas

I address how I personally cope with all these frustrations in the following video. If you have any of your own personal tips or techniques, I’d love to hear them.

Hello React.JS – Absolute Beginners Guide to React

In this video I’ll walk you through how to create a basic Hello World application with React.JS.

After spending a few months learning React.JS and following all of the official and unofficial tutorials, I found that there was a gap in the information. My goal with this video is to bridge that gap and show you some of the tips and tricks that most of the tutorials don’t teach.

Here are the links you’ll need to follow along:

How to install Node.JS v6 on Linux

This video is a step-by-step instruction of installing Node.JS version 6 on Ubuntu or Linux Mint. Hint: As tempting as it might be, don’t install it through the package manager. I’ll explain why in the video below.

Introduction to the Python Debugger Tool

In this video demonstration, I’ll show you how to get started with the Python Debugger tool.

The Python Debugger (PDB) is an incredibly useful tool which can save you hours when writing Python applications.

This tool has replaced my former debugging process – which was laborious and not at all efficient. I use it whenever I’m debugging my code or troubleshooting issues.

Install and configure PyEnv on Linux

PyEnv is a great tool for installing and switching between different versions of Python, which is particularly helpful if you’re working on multiple projects or for multiple companies that use different versions of Python. In this video, I’ll show you how to install and configure PyEnv on Linux, but these steps should also work on Mac.

Dockerizing a Django REST Framework Project

In this video I’ll show you how to create a Docker container for a Django REST Framework project. This video was inspired by my Build a REST API course on Udemy. In the course, I build a REST API using Vagrant, but Vagrant is not the only way. You can use Docker, it just has a steeper learning curve.

How I became a professional developer

So I thought in this post I’d do something a bit different and I’ll go through my journey as a professional software engineer.

I’m a full-stack software engineer, that means that I work in all different languages from the backend to the frontend, so I can do backend DevOps, hosting and server administration. I can also do programming in Python and frontend development in JavaScript and some Android and AngularJS.

The way that I got into programming was I started when I was 12 years old. I got my first computer and I was just fascinated with making applications and I was really curious about how to make your own programs on the computer.

I think it was a Windows 98 or Windows ME machine, so very old from modern standards.

I looked up how to program and I asked my parents and they didn’t know because, I mean, it’s not something you know — especially back then — unless you’re a professional working with computers.
