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.

Including Attractive Charts In Your Angular Web Application

It’s probably obvious, but most modern applications crave data and in many of those scenarios, being able to visualize the data is a necessity. This is where charting and graphs become valuable within frontend applications. Having attractive charts in your application can make a world of difference and with a convenient library like Chart.js, it isn’t complicated.

If you’ve been keeping up, you’ll remember I wrote a tutorial titled, Use Chart.js to Display Attractive Charts in a Vue.js Web Application which focused on Vue.js. This time around we’re going to see how to include charts in an Angular web application.

Use Chart.js To Display Attractive Charts In A Vue.js Web Application

Charts are a great way to illustrate data within an application. No one likes trying to make sense of raw data or looking at it via a table. Instead a nice bar chart or line graph can paint a perfect picture of what’s going on.

There are a lot of charting libraries available, but my personal favorite is Chart.js. It is a vanilla JavaScript library, so including it within a framework can be a little intimidating.

We’re going to see how to work with Chart.js within a project that uses the Vue.js JavaScript framework.

Using Charts In Your Ionic Framework Mobile App

I’m always trying to add more flair to the mobile applications that I develop whether it be through slick user interfaces or graphics. For a while now I’ve wanted to mess around with charts in my mobile applications, but it kept getting pushed to my development back-burner.

I decided to push myself to give it a shot. Using Ionic Framework to build mobile Android and iOS applications, you’re left with a few possibilities for adding charts because so many JavaScript libraries exist. In particular, we’re going to take a look at Chart.js and the AngularJS wrapper, Angular Chart. We’re going to look at this library because not only does it look great, but it plays nice with AngularJS which is what Ionic Framework is built upon.

Create A Minesweeper Game With Native Android

So recently I was presented with a challenge. Make a Minesweeper game using native Android with no additional frameworks such as Unity3D or similar.

Minesweeper via Wikipedia:

A single-player puzzle video game. The objective of the game is to clear a rectangular board containing hidden “mines” without detonating any of them, with help from clues about the number of neighboring mines in each field.

This task can be accomplished many ways. For example we could choose to use OpenGL, a 2D canvas, or something else. In this particular tutorial we’re going to be using a 2D canvas because it is simple and acceptable for a game with minimal to no animations.;

Various Graph Search Algorithms Using Java

If you’ve been keeping up with my blog, I’ve made a topic regarding Binary Search Trees, but another very important topic in computer science and software engineering is in regards to Graphs.

Graphs via Wikipedia:

A graph data structure consists of a finite (and possibly mutable) set of nodes or vertices, together with a set of ordered pairs of these nodes (or, in some cases, a set of unordered pairs). These pairs are known as edges or arcs.

When interviewing for a new programming or software engineering position, it is incredibly likely that you are asked a question on this topic. Because of this, I figured it would be a good idea to go over a few of the Graph search algorithms.
