Unwanted AI bias is already a widespread problem. Machine learning models can replicate or exacerbate existing biases, often in ways that are not detected until release. So what can be done about it?

We reduce boilerplate with common OOP patterns, but often, the code overhead of using patterns is almost the same—if not bigger—than if we’d used boilerplate code in the first place.

In aspect-oriented programming tutorial, we implement two functions (aspects) that allow for generic database connection management and caching. These allow us to mark methods that, when called, will automatically have the required functionally present in through IL weaving.

Migrating in either direction between Microsoft SQL Server and Oracle Database? There are some significant pitfalls to be aware of…

Data collection and preparation slow down traditional NLP projects. However, transfer learning and BERT can reduce the amount of data required and change the way companies execute NLP projects.

Nearly every app requires an authorization system on top of an authentication system. We often need a fine-grained permissions model to allow only specific users to access certain resources while simultaneously restricting access for everyone else.

In this tutorial, Toptal Freelance Firebase Developer Joaquin Cid teaches how to build just such a system. Called role-based authentication, we’ll learn how to implement this system in an API using Node.js and Firebase.

Subscription-based apps need a special approach when it comes to analytics. Learn how a variation on the traditional sales funnel helps you work with LTV, subscriber retention, and churn rates to make your app better—and more profitable.

SQL window functions are calculation functions similar to aggregate functions but, unlike normal aggregate functions like “group by,” have access to individual rows and can even add some of their attributes into the result set.

In this article, Toptal Freelance SQL Developer Neal Barnett explains the benefits of SQL functions, describes when you’d use them, and gives you real examples to help with the concepts.
