My Journey into Backend Development

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

I remember after I got my laptop, I dove into backend development immediately. Little did I know that there were some “interesting” challenges ahead.My name is Chris Friday, and I am a Python programmer and an aspiring Backend engineer. I have been into backend development for almost two months, and I honestly must confess it’s quite amazing and thrilling to make a website come to life with a brilliant use of logic, database manipulations, and all the nitty-gritty of backend stuff.I remember very vividly when I was working on a Trip app project using Django, and I ran into a…

stp2y0 CommentsNewscoding, community, database, development, engineering, inclusive, kubernetes, opensource, postgres, software

If you are learning about databases and Kubernetes or running or migrating PostgreSQL to Kubernetes, I want to show you a great open-source tool for database monitoring and troubleshooting. I will discuss a tool to help you better understand your database, its parameters, and its health. You can access a Query Analytics tool to help you find slow queries. In addition, you will have dashboards to monitor the Kubernetes cluster itself. In the previous article, I discussed the pgAdmin and PostgreSQL cluster created using Percona Everest. Today, I installed Percona Monitoring and Management (PMM) in my cluster, made some test…

Strong Performance with EC2, Lambda, and the Momento SDK for Rust

stp2y0 CommentsNewsarchitecture, aws, coding, community, development, engineering, inclusive, rust, serverless, software

I wrote recently about Mind Boggling Speed with Caching with Momento and Rust and wanted to continue in that theme as I explore the Momento SDK for Rust. Caching is a technique that builders reach for when looking to accomplish either improved performance or reduce the burden on resource-dependent parts of an application. It might also be a choice when looking to save costs if an operation is charged per read such as with DynamoDB. In any of those scenarios, caching must be fast. But caching must not also introduce a high amount of complexity. This is where I love…

What is Associative Arrays in Computer Science

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, programming, software, tutorial, webdev

In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with a finite domain. It supports 'lookup', 'remove', and 'insert' operations. The Dictionary Problem The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays. The two major solutions to the dictionary problem are hash tables and search trees. It is sometimes also possible to solve the problem using directly…

Scaling databases with AWS RDS and read replicas

stp2y0 CommentsNewsaws, cloud, coding, community, database, development, engineering, inclusive, software, tutorial

Amazon Web Services (AWS) Relational Database Service (RDS) is a managed service that simplifies the process of configuring, operating, and scaling a relational database in the cloud. AWS RDS is a versatile choice that supports several database engines including PostgreSQL, MySQL, Oracle, MariaDB, Microsoft SQL Server, and Amazon's own Aurora. Advantages of using RDS over a self hosted database Managed Service - AWS RDS is a fully managed service, which means that AWS takes care of provisioning, patching, backup, recovery, and even scaling. This allows developers and database administrators to focus on the application development and optimization rather than managing…
