Prop Drilling is the act of passing data, in this case, react props, through several nested layers of components before it reaches the component that needs the data. Is this a problem in and of itself? It depends (which is the best answer for a question). Props are part of the “React way” of managing state, so using them, even passing them through nested components, isn’t necessarily bad. It depends on the scale. For small applications, this is not an issue. You can use either of the approache

Why are software development estimations so hard to get right? Here are some ways to get more accurate.

Anyone who's written a Domain-specific language (DSL) or found themselves accidentally entrenched in a shotgun parser knows the pains involved in processing a grammar. We found ourselves needing to take a predefined Abstract Syntax Tree (AST) and generate a UI from it. The pain we experienced along the way forced us into a disciplined simplicity from which some pretty useful design patterns emerged. In this blog post, we share the lessons we learned from situations where complexity led us into a

How we bridged Backend with Frontend by converting template syntax and how AI helped. What is templating? In web templating, a template acts as a blueprint or a skeleton for the web page. It contains the static parts of the page layout and defines placeholders or variables where dynamic content can be inserted. I believe every developer is familiar with it, as it comes from the ‘ancient’ web development times and has been around for decades. The ISML templating ISML stands for “Intershop

Your site has gone down. Users are contacting you for support, but you have no idea what could be causing the issue. Mild panic sets in. This scenario is all too common, and recently, I also encountered this issue. It turned out that the problem was not in the code I had recently written; but in my failure to realize the software development kit (SDK) I was using was deprecated. This article will explore the risks of using an outdated SDK and provide tips to avoid its pitfalls. So, what exa

A note to preface: you can find the project repository here. The origin story After a while developing software in Java, I was intrigued by all the praise of Kotlin and also interested in Kotlin/Native as a way to develop applications that don't require a VM to run. Inspired by this Golang implementation of traceroute, I settled on trying my hand at implementing traceroute with Kotlin/Native. tracerte is already available on every operating system, so why the hell would I rewrite it? Good qu

Package management can be something of a headache, but it doesn't have to be that way. Here's some tips to get you on your way with Maven Central.

With a React frontend, Django isn't responsible for the frontend and doesn't know how to start the frontend process. This causes the tests to fail due to there being no frontend to interact with. To fix the failing tests we need to have the frontend running when running the integration tests.

We recently completed a project with one of the largest affiliate marketing consulting firms in the US which turned out to be a great success for everyone involved. We asked one of the lead consultants on the project, Jason Lombardo, to answer a few questions.

Our project began with a small ask: build a small Python back-end using AWS Lambda and API Gateway (with just a handful of endpoints to support a few pages) and use Serverless [https://serverless.com/] to manage the Cloud Formation setup. Not very involved, not much code, not even much configuration for the deploy. Next came authentication. In pursuing the joint dreams of DRTW ("don't reinvent the wheel") and WALCAP ("write as little code as possible"), we selected AWS Cognito over other opti
