Machine Learning: The Time is Now!

David Pitt Machine Learning, React, Tutorial Leave a Comment

Machine Learning enables a system to automatically learn and progress from experience without being explicitly programmed. It’s a subset of the artificial intelligence (AI) technology space being applied and used throughout your everyday life. Think Siri, Alexa, toll booth scanners, text transcription of voicemails – these types of tools are used by just about everyone.

Image recognition and computer vision are also widely being used in production; recently just heard that Los Angeles, CA has made it illegal for law enforcement to use face recognition technology in its numerous public video cameras. The current state of the art allows real-time identification.

Interestingly, the algorithms and know-how for Machine Learning have been around for a long time. Artificial Intelligence was coined and researched as far back as the late 1950s, the advent of the digital computer, and expert systems and neural networks, that theoretically mimics how our brain learns.

The increase in Machine Learning production-ready applications started around 2012, with increased processing, bandwidth, and internet throughput power. This is important as deep learning algorithms like Neural Networks require lots of data and FPUs/GPUs to train.

In this blog, we introduce a conceptual overview of Neural Networks with a simple Neural Net code example implementation using Go. We will interact with it by building a ReactJS interface and train the Neural Network to recognize hand-drawn images of the numbers 0-9. Let’s dive in….

JavaScript Bake-Off: Angular, React, and Vue

David Pitt Angular, JavaScript, Opinion, React, Single-Page Application, Vue Leave a Comment

As Keyhole consultants, we are exposed to a plethora of technology stacks and implementations from client project to client project. Particularly with our enterprise clients, great care must go into selecting the best technologies for the company’s technical needs and current landscape. After all, they don’t want to be re-writing the same application in just a couple of years due to lackluster choices and shortage of developers to add functionality.

In this post, we present an open source reference application developed three times using three different frameworks, React, Vue & Angular.

Blockchain Implementation With Java Code

David Pitt Blockchain, Java 2 Comments

Bitcoin is hot — and what an understatement that is. While the future of cryptocurrency is somewhat uncertain, blockchain, the technology used to drive Bitcoin, is also very popular.

Blockchain has an almost endless application scope. It also, arguably, has the potential to disrupt enterprise automation. There is a lot of information available covering what and how blockchain works. We have a free whitepaper that goes into blockchain technology (no registration required).

This blog will focus on the blockchain architecture, particularly demonstrating how the “immutable, append-only” distributed ledger works with simplistic code examples.

As developers, seeing things in code can be much more useful in understanding how it works, than simply reading technical articles. At least that’s the case for me. Let’s get started.

How an SMS Application Took a Job (i.e. Task)

David Pitt Conversational Apps, JavaScript, Keyhole Creations Leave a Comment

This blog is about a human’s job being replaced by automation. But, before you start composing emails and social media responses, know that it’s a job that I think most folks would gladly allow an automated mechanism to take over.

The “job” discussed in this blog is the need to contact individual users (in this case, employees) when those users forgot to accomplish a required task.

In this blog, we discuss a conversational application solution used internally at Keyhole Software for automated SMS text messaging features surrounding time tracking. The solution, implemented with conversational application platform KHS {Convo}, allowed for time entries to be submitted via text and automated, schedule-based notifications….
