Working with big data databases in Delphi – Cassandra, Couchbase and MongoDB (Part 3 of 3)

This final part of our trilogy on big data databases introduces a Delphi driver for MongoDB. This driver is independent from any other data access frameworks in Delphi and provides direct and efficient access to data on a MongoDB server. The previous posts in this series focus on Cassandra and Couchbase. For more information about… Continue reading Working with big data databases in Delphi – Cassandra, Couchbase and MongoDB (Part 3 of 3)

Face Detection on Android and iOS

Android and iOS have built-in support for detecting faces in photos. We present a small platform-independent abstraction layer to access this functionality through a uniform interface. You can find the source code on GitHub as part of our JustAddCode repository. Like we did in our post on Cross Platform Text-to-Speech, we expose the functionality through a Delphi… Continue reading Face Detection on Android and iOS

Experiments in Uniform Memory Management

We experiment with algorithms to make memory management in Delphi more consistent between desktop and mobile platforms. This eases debugging and finding memory leaks. We look into using object interfaces and semi-automatic memory management based on ownership. Along the way, we touch on using linked lists and Delphi’s messaging framework. Warning: this post is more… Continue reading Experiments in Uniform Memory Management

Using Google Sign-In for Firebase SDK on Android

In this article we will show you how to use Google’s Firebase SDK for sign-in on Android devices. While most login implementations launch a web browser to start an OAuth/2 flow even in Windows, iOS and Android apps, we will be demonstrating how to directly use the Google SignIn SDK in your app to present… Continue reading Using Google Sign-In for Firebase SDK on Android

SIMD Assembly Optimization

We get close to the metal as we demonstrate how you can incorporate assembly optimized SIMD routines into your Delphi apps. This can be done by using inline assembly code for Intel platforms, or by creating and linking a static library for ARM platforms. Nowadays, with optimizing and vectorizing compilers, few people still hand-write assembly… Continue reading SIMD Assembly Optimization
