TPDP Episode #22: NoSQL Databases And The Flexibility Of A Non-Relational Model

I am pleased to announce that the latest episode of The Polyglot Developer Podcast is now available for download. In this episode titled, NoSQL Databases and the Flexibility of a Non-Relational Model, I’m joined by Matt Groves where we talk about use-cases for NoSQL versus relational databases and how to use NoSQL in your own applications.

Matt Groves and I used to work together at Couchbase, which is a NoSQL database company, and is by no means the focus of this episode. The focus is NoSQL in general and all the great things that you can do with it.

Developing A RESTful API With Node.js And MongoDB Atlas

Most modern web applications need to be able to handle data consumption requests and data manipulation requests from clients using HTTP. It is the norm to pass JSON data between these requests so it makes sense to use a NoSQL document database because JSON and similar is the common storage format, eliminating the need to marshal data to new formats in every request.

Lucky for us, leveraging these concepts and technologies is not a difficult task.

We’re going to see how to create a RESTful API using Node.js and Express Framework that communicates to a cloud instance of MongoDB called Atlas.

Creating A Basic Chrome Extension

Chrome Extensions have been around for a long time. I believe they are a very under-explored technology - and if you’re a traditional web developer, there’s a very small learning curve since Chrome Extensions are comprised of HTML, JavaScript and CSS. Bonus - you don’t have to worry about every browser under the sun, just Chrome! (though Firefox is becoming extension-friendly, it might be a good idea to not include Chrome-only web features).

Peer-To-Peer Storage With A Raspberry Pi And Resilio Sync

I’ve been slowly trying to cut down on my online file storage footprint by switching to software and tools that I’m in full control over. For example, I was once a very heavy user of Dropbox and similar tools when it came to transferring files around between my computers, but that could leave my files exposed in the cloud, not to mention it was slow due to the time it took to communicate with the remote server.

This is where Resilio Sync comes into play. Once called, BitTorrent Sync, this software allows you to transfer files between devices on your network, without a middleman, in a peer-to-peer (P2P) fashion, like you would find with the popular BitTorrent protocol. The more devices, the faster the synchronization.

We’re going to see how to install and configure Resilio Sync on a Raspberry Pi to act as a synchronization node on your network for file storage and fast transfers.

Inheritance And Composition In A PHP Application

As developers, we have encountered scenarios where some of the code we write can be reused by other code pieces. This has brought the concepts of code reuse in paradigms like object oriented programming. In this article, the author seeks to explain when to reuse code as well as how to achieve code reuse.

TPDP Episode #21: Developer Evangelism

I am pleased to announce that the latest episode of The Polyglot Developer Podcast, titled, Developer Evangelism, is available for download on all the major podcast networks.

In this episode I’m joined by Matthew Revell, founder of Hoopy and DevRelCon, where we discuss a potential career path for developers and marketers known as Developer Evangelism.

Profiling UI Layouts In Android For Performance Improvements

Something that any application should be concerned with is performance. One way to look at performance is via profiling. Most IDEs and platforms provide tools to profile your application to take a look at detailed system information about various parts of your application. With Android applications you can execute an adb command to generate a very thorough snapshot of the graphics information and that’s what we’re going to look at in this post.
