Learning Angular C.R.U.D.

Chris Berry Angular, Articles, Development Technologies & Tools, JavaScript, Tutorial 5 Comments

So, you’ve learned JavaScript and now you’re wanting to get into Angular. But where do you start?

There are quite a few examples out there. One of the best ideas I have personally found useful for a new developer to learn is how to do Create, Read, Update and Delete operations.

In this blog we’ll go through the process of building a simple, working Angular address book application with C.R.U.D. operations. By the end, and by studying the full, working code, you should have a better grasp on Angular.

Keyhole Labs Releases Trouble Maker v2.0.0

The Keyhole Labs team has announced the release of Trouble Maker v2.0.0.

Trouble Maker is a platform-agnostic tool that randomly takes down services to test stability. It also provides an ad hoc console to produce common troublesome issues in your platform so you can test durability on-demand.

Trouble Maker v2.0.0 introduces specific performance improvements implemented with Spring Boot and Java Websockets. Additionally, the Trouble Maker dashboard user interface has been re-designed, built from the ground up using Angular 2…

Taking A Mixed Approach To Single-Page Applications

Chris Berry Angular, Articles, Development Technologies & Tools, JavaScript, Single-Page Application Leave a Comment

A coworker came to me with a problem. The client he was working with would be building hundreds of single-page applications and all would need to be tied into a single shell application. He had first attempted to use an iFrame contained within another single-page application to display the child applications.

While this worked, he came up against another requirement: the child applications may or may not need access to data from the parent shell application.

It was at this point he came to me for suggestions. I had been playing with this exact idea for sometime; how can you manage a collection of Single-Page Applications and still share data between them?

At this point, I decided to create a hybrid solution of mixing Single-Page Applications with a server-rendered shell application. The following is the process I took for creating this solution, highlighting some of the pain points with some suggestions for further enhancements.

We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.

The basic flow of this post will be:

Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy

Coding For Fun: MIT Battlecode Challenge 2017

Joshua Robinson Articles, Community, Development Technologies & Tools, Educational Event, Programming Leave a Comment

I recently participated in the month-long MIT Battlecode competition where I programmed a team of virtual robots that competed against another team in a real-time strategy game. In this blog, I discuss some of the lessons learned during the programming competition. I was surprised how much of it could be used as a lesson in the real-world of programming!

We’re in this industry because we love programming and writing code. It is in this spirit that I suggest to all readers to consider challenging yourself and doing something similar to “code for fun” and improve your skills!
