Measure Code Quality using Cyclomatic Complexity
The article talks about how McCabe’s cyclomatic complexity could be used to measure several different aspects of code quality. The objective of this article is to help developers quickly assess code quality by looking at the code. However, let’s try and quickly understand what is cyclomatic complexity and how could it be measured? Thanks for reading it further. And, apologies for spelling mistakes. What is Cyclomatic Complexity? Cyclomatic complexity is a measure of code quality that takes into account the number of independent paths through a piece of code. A high cyclomatic complexity indicates that a piece of code is more difficult to understand and maintain, and is, therefore, more …
Checklist for Effective Code Review

GitFlow Workflow Best Practices & Quiz Questions
In this post, you will learn about some of the best practices in relation to managing your development and production releases using GitFlow Workflow. There will be a master branch which is called as an official repository. Forking a develop branch of the master: To start with, we will fork off another branch of the master which we may call as “develop”. This branch will act as an integration branch for features branches. NOTE: feature in features branches does not represent the features in machine learning. “Develop” branch will act as a parent to the feature branches. This means that developers would fork from “develop” branch and their changes are merged back into “develop” branch. In real-world scenarios, …

Top 5 Performance So-called Concerns of Meteor JS
Many working with Meteor JS wonders about performance concerns associated with Meteor JS. This blog points some of those concerns and represents my opinion on why they are invalid concerns. Database as a Bottleneck Inability to handle heavy read-write loads, especially, write load/performance; However, with latest releases of MongoDB, MongoDB is good enough to easily handle very large data requirements of read/write. Following are related details: MongoDB supports different techniques to scale out appropriately based on the read-write requirements. They are as following: Secondary reads (reads from slaves, writes from primary/master). Sharding techniques MongoDB (3.0+) has come up with new storage engine, WiredTiger, which supports document-level concurrency control for write …
