Using Dapper Flexibly

Jason Schmidtlein .NET, Problem Solving, Technology Snapshot Leave a Comment

Dapper is a micro ORM (Object Relational Mapper) for .NET that is nearly as fast as using a raw ADO.NET data reader. It is a great alternative to Entity Framework, especially when performance is a top priority and you don’t need all the features of a “heavy” ORM.

In this post, I will provide an example of creating a generic CRUD repository that leverages the performance of Dapper while providing flexibility for a multitude of scenarios..

Gaining Docker Image Size Efficiencies By Separating Application Layers

Luke Patterson Docker, Java, Problem Solving, Spring Boot, Technology Snapshot Leave a Comment

Problem

I was pushing a new Docker image tag for each application code commit, and the admins of the private registry were getting annoyed at how much space I was using.

Solution Summary

Yes, I know there are strategies to clean up old tags but I first wanted to reduce the impact of the tags I was pushing. With the right layering strategy, I knew I could reduce the net registry size increase of consecutive tag pushes.

I wanted to only push what had actually changed in the application. In addition to reducing the impact on the registry, having smaller tag deltas could possibly speed up rolling deployments since nodes could potentially have less to download.

Refreshing Your Scrum

Keith Shakib Agile, Consulting, Design, Dev Methodologies, Problem Solving, Soft Skills 3 Comments

Most of us now have some experience with Agile Scrum practices. Many of us have had years of practice on multiple processes. As a consultant, I have the opportunity to see many differences in how organizations implement and practice the most popular development process methodologies.

While the prescription for good practices is well-documented, many of us have lost our “mojo” at least once and seen many of the benefits of using the process decline.

In this blog, I will indicate some key points required to return to optimal agile performance. I will highlight three common pitfalls, some common causes of those problems, and reminders of how to get back to a high-performance Scrum implementation. Let’s dive in.

Improving Performance in React Applications

Adrienne Gessler Design, JavaScript, Problem Solving, React 2 Comments

Let’s say you’ve stepped into a React application to make some updates or been involved in building one yourself. You have been at it a while, and feel somewhat comfortable using React, you understand React’s lifecycle and you may be using React libraries like Redux or MobX to some extent.

As with any technology, you start to notice that a few of the pages are looking a little slow. You know performance tuning too early is often a bad idea, but you feel like you might be at that point. After all, in your experience, end users notice even small lags and no one wants that. So what do you do now?

In this blog, I introduce six tips for improving performance and design in your React application.

State Management with MobX and React

There are many options when it comes to managing the state of a React application. Choosing the right one for your application can feel daunting.

The most popular choice, Redux, is often thought of as verbose because it requires a lot of boilerplate code, thus slowing down development. Redux is also very opinionated so it will take time for those unfamiliar with its functional programming paradigm to become comfortable with it.

In this blog, we’ll take a closer look at an alternative that aims to solve issues in React application state: MobX. To do that, I built a simple calorie counter application that will be used to showcase MobX in use.
