User engagement means how much a person uses an app and stays interested in it. It's super important for developers to give users good reasons to keep using their app. In mobile marketing, a big goal is to get more people engaged with apps. This can be done in different ways like sending them emails that they're interested in, making content that's just for them, and trying out new marketing ideas.
In this series, we have looked at the "musts" (databases) and "shoulds" (asynchronous jobs, websockets) of a web application. Now we turn to one of the "coulds" (that is nonetheless recommended for scaling businesses): caching. In particular, we mean caching HTML fragments and other snippets of data, as referred to in Rails Guides. We are not concerned with HTTP or SQL query caching. In this part, we'll see how to speed up our Rails app using LiteCache.
Welcome to part two of our series on profiling and optimizing CPU-bound tasks in Node.js!

At most federal government agencies, acquisition teams are understaffed and overworked. They have open positions that they can’t seem to fill. And their acquisition “systems” aren’t helping matters. Rather than working with one integrated government acquisition system, many agencies rely on separate applications that each perform one function. And the applications don’t communicate with each other or integrate with the financial system.
Design patterns can help to simplify your codebase so you don't need to reinvent the wheel. In this post, we'll go into how to use Draper. But first, we will start with an overview of the decorator pattern and how to use it with Ruby's standard library. Let's get started!

Parallel processing in computers is like having an efficient team working on different parts of a task simultaneously. In traditional programming, tasks are executed one after the other, like solving a puzzle piece by piece. However, parallel processing divides the task into smaller chunks, and these chunks are handled simultaneously by multiple processors or cores. Python provides modules that allow programs to leverage multiple processor cores efficiently.
Businesses are in a persistent productivity slump that could last through 2030, according to a 2023 World Bank study. The tech boom that powered innovation and growth over the last three decades is fading. Many companies are counting on artificial intelligence (AI) to boost operational efficiency and counteract these alarming trends.
JVM uses threads to execute every single operation. And during its lifetime, these threads can go through various stages. One such stage, where the threads are unable to move any further or are blocked from operating is called as the thread-waiting situation. There are various scenarios in which a thread can enter a waiting state. Identifying and diagnosing thread-waiting situations is important for maintaining the performance and reliability of multithreaded applications.
