Criteria is a framework-agnostic PHP package that simplifies the use of the criteria pattern for filtering, sorting, and paginating data. It helps separate query logic from repositories, making the codebase easier to maintain and extend over time. By using Criteria, developers can handle complex querying needs without spreading filter logic across different parts of the application.
Guard clauses are a practical way to write cleaner functions by handling the unwanted cases first. Instead of nesting your entire function inside a stack of if conditions, you check for the early exits up front - returning or throwing as needed - and move on. It's a habit that keeps code flatter and easier to read. The structure becomes simpler, and it’s immediately clear what the function does and under what conditions it doesn’t even bother.
In Agile, measuring success isn't just about counting completed tasks - it's about ensuring teams continuously improve while delivering value. Without metrics, teams might feel like they're making progress, but they wouldn’t have clear evidence of what's working and what isn't. The right metrics give teams visibility into their workflow, highlight areas for improvement, and help them make better decisions. But Agile isn't about chasing numbers - metrics should support improvement, not dictate behavior.
Adjusting a fan's speed using an Arduino is a great way to learn about PWM (Pulse Width Modulation) and motor control. With just a potentiometer and some simple wiring, you can create a smooth, manual speed adjustment system. This setup is useful for cooling electronics, ventilation projects, or any application where adjustable airflow is needed.
Agile helps teams adapt, deliver value faster, and improve continuously. However, applying Agile in real projects is not always smooth. Teams often run into resistance to change, unclear priorities, inefficient collaboration, and struggles with Agile scaling.
These challenges can slow down progress, frustrate teams, and make Agile feel like more effort than it's worth. But the good news is that Agile itself provides ways to address these problems. Recognizing common obstacles and knowing how to handle them helps teams get the most out of Agile without falling into frustration or inefficiency.
Motion sensors are essential in modern automation projects, playing a key role in security systems, smart lighting, and interactive devices. These sensors detect movement and trigger specific actions, making them useful for various applications. When paired with an Arduino, a motion sensor can be programmed to respond intelligently, creating an efficient and responsive system. This guide explains how motion sensors work, how to connect them to an Arduino, and how to write the code needed to make them function properly.
Agile is all about flexibility, but that does not mean teams work without organization. To stay aligned, productive, and continuously improve, Agile teams follow structured routines called ceremonies. These ceremonies provide opportunities to plan work, track progress, and reflect on how to get better.
Agile teams are designed to be flexible and collaborative, but that does not mean everyone does everything. To stay effective, Agile teams rely on well-defined roles that help organize work, support decision-making, and keep projects moving forward. While different Agile frameworks may use slightly different role names, three key responsibilities exist in almost every Agile team: the product owner, the development team, and the scrum master.
Managing a project means making choices about how to plan, track progress, and handle unexpected changes. For years, traditional project management methods, often called waterfall, were the standard. These methods rely on detailed upfront planning, structured phases, and a clear path from start to finish. Every step is carefully mapped out, leaving little room for adjustments once the project is in motion.
The way teams build products, develop software, and manage projects has changed a lot over the years. Traditional project management methods often struggle to keep up with shifting priorities, unexpected challenges, and fast-moving markets. That's where Agile comes in. Originally designed for software development, Agile has grown into a popular way of working across different industries. But what does it really mean to be Agile?
