Originally, this was going to be an article on how to use specific tools for an AI data pipeline and how to train a specific machine learning model. However, it is the concepts of data engineering and the data pipeline which are important. While some of the tools will be used across projects and companies, […]

Writing smart contracts with Rust and CosmWasm for Cosmos blockchains is fun to do.
We’re going to walk through the basics of machine learning and applying it to the problem of email spam prediction. We are going to do this by loading training data sets, building a few machine learning models and then checking their performance on test data sets. The data sets we are using are small enough […]

SCRUM Methodology
For project managers who are training in SCRUM agile, here is a reference. In SCRUM user stories are added to a product backlog, which are organized and prioritized by the product owner into a sprint backlog. The work that needs to be done is in that sprint backlog and is worked through and checked on […]

Coaching as a Team Leader
In this article, I talk about how a team lead should be a coach and mentor to the team. I talk about a few scenarios and about the contrasts between the “coach” and “fixer” mindsets that leaders can adapt. This applies in other management and leadership positions, but the example I’m using is one specifically […]
Reactive programming is a concept that is finally gaining some popularity among programmers. It makes it easier to think in data flows and to manage and work with them. Instead of imperative programming, you’re thinking about code as a series of processes that take place on streams. This is similar to the conceptual shift to […]
There comes a time in the life of every Ruby on Rails project where you and your team will end up with long running tests. Rails tests can contain factories, fixtures and lots of setup procedures before tests are executed, and all of these can contribute to major slowness in the test runs. I’ve seen […]
As part of a prototype/exploratory project in March 2016, I explored how to build a GraphQL server using Node.js and interfacing with a MongoDB database using the Mongoose library. The best reason to use GraphQL is if you have multiple frontend clients that communicate with your backend and they each have differing data needs. For […]
I was in Montreal, Canada for the PyCon Canada 2017 conference and presented on the ideas and philosophy that are present within the Python programming language. I covered how the Python language influences your coding style and how that coding style is now in the mainstream and has made its way into other programming languages. […]
