Validate Bracket And Parenthesis Combos Using Stacks

Job interviews for software engineering and other programming positions can be tough. There are too many things to study, and even then it still might not be enough. Previously I had written about a common Fibonacci number algorithm and finding duplicate values in array.

Those skill refreshers were written in JavaScript. This time we are going to take a turn and validate bracket combinations using the Java programming language.

Prompt User To Rate Ionic Framework Mobile App

So you’ve released a great mobile app and have had a decent amount of downloads, but no one is rating or reviewing it. Downloads can be increased significantly by having a greater number of ratings.

So how do you encourage more downloads in your Ionic Framework Android or iOS mobile application? Thanks to a library created by Alex Disler called ng-special-offer, we can make use of Apache Cordova native dialogs to prompt users to rate or review based on application open count.

Calculate If Duplicates Exist In An Array Using JavaScript

You’ll notice previously I did a post regarding the Fibonacci number, a popular interview question for programming jobs. To keep up with this trend of interview questions, we’re going to look into the different ways of finding duplicates in an array.

Finding array duplicates is a good question because it tests your knowledge of algorithm design and your understanding of various time complexities.

Use The Ionic CLI To Integrate Crosswalk Into Your Project

Not too long ago I wrote a very popular tutorial for integrating Crosswalk into your Ionic Framework mobile application. Since then, the guys at Ionic released version 1.3.2 of their CLI and it makes the process even easier than I had previously demonstrated.

The CLI integration is still beta and there is a lot of confusion around it, but this article should clear things up in regards to its usage.

The Fibonacci Sequence Printed With JavaScript

If you’re familiar with the material I write on my blog, you’ll probably be confused at why I’m making such a post. Anyone who has been a part of a Computer Science program at a university will probably have dabbled with Fibonacci in their first semester of school. However, many Computer Science graduates don’t realize that this is a common job interview question regardless of the company or job level that you’re applying for. Whether you’re applying for a new graduate position or a senior level position, there is a good chance you’re going to be screened with a question on this topic.

With that said, I think this can be a refresher to anyone going through the interview process for a programming or software engineering position.

Monitor MySQL And Auto Recover From A Crash

Since starting this blog in July of 2014, I have had an unexpected amount of growth. So much, that a lot of strain has been placed on my virtual private server (VPS).

A common issue that has plagued me and many other WordPress users is the awful MySQL crash due to exhausted resources. This is because the server has run out of resources due to traffic spikes or other anomalies. The worst part for me is that MySQL tends to crash while I’m sleeping, putting my blog out of commission for up to six hours at a time. This is not good when you’re trying to be a reliable source of information on the internet.

Luckily, I’ve developed a script that will elegantly resolve these related problems.

Embed Video In Your iOS And Android Ionic Framework App

I’ve received a few requests from my subscribers for an article regarding embedding videos in their Ionic Framework application. This could be a challenging task for a few reasons. There are known issues with the HTML5 <video> tag for Android. One might also ask how to make the videos responsive for multiple screen resolutions.

In this guide, I’m going to show how to do responsive embeds of YouTube videos into an Ionic Framework list of cards.
