KeyholeSoftware.dev—the innovation arm of Keyhole Software—has released a new open-source HTTP load testing command line utility implemented in Go. khsLoad is used to test the performance of APIs and websites through user simulation with features for creating data graphs useful for SLAs.
Go With A Vue
Last year I blogged about creating a Lean Mean Vue Machine called Quotes on Demand. The application was a fully-featured CRUD application served from a NodeJS server and had a self-contained VueJS front end. Since then I’ve also added a Python version of the same API.
But wouldn’t it be a nice test to see if that same Vue application could switch over to another API – say, something like a Golang application server?
In this post, we will create a Golang application server that will have 100% parity to an existing NodeJS web application. This will enable an existing VueJS front end to connect to the application with no additional code changes in the user interface code.
Go “On The Fly”
People that know me, know that I love to fly fish and tie flies. I made up the saying “Time flies when you’re tying flies.” It is true, just like when you are trying to solve a programming problem, time flies.
Over the past few years, we at Keyhole have utilized Docker (with assorted technologies) and have gotten up to speed on the Hyperledger blockchain framework. Something that all of these technologies have in common is the Go language. Go is the language used to implement Docker, Hyperledger, OpenShift, and many other system-level applications.
Personally, I like to peek under the hood to better understand the tools I’m using. That led me to learning about the Go language. And in my opinion, the best way to learn a language is to build something.
So, I built an application for fly tying videos. There are numerous fly tying tutorials on YouTube, so I built an application that allows them to be organized into virtual fly boxes and types.
In this blog, I will introduce you to the Go language. We’ll go over some of the key language concepts by walking through how the https://flytyerworld.com server-side API is implemented using Go.
Machine Learning: The Time is Now!
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….
