The Four Pillars of Programming Logic in Software Quality Engineering

Aggregated on: 2024-02-12 19:32:08

Software development, like constructing any intricate masterpiece, requires a strong foundation. This foundation isn't just made of lines of code, but also of solid logic. Just as architects rely on the laws of physics, programmers use the principles of logic. This article showcases the fundamentals of four powerful pillars of logic, each offering unique capabilities to shape and empower creations of quality. Imagine these pillars as bridges connecting different aspects of quality in our code. Propositional logic, the simplest among them, lays the groundwork with clear-cut true and false statements, like the building blocks of your structure. Then comes predicate logic, a more expressive cousin, allowing us to define complex relationships and variables, adding intricate details and dynamic behaviors. But software doesn't exist in a vacuum — temporal logic steps in, enabling us to reason about the flow of time within our program, ensuring actions happen in the right sequence and at the right moments. Finally, fuzzy logic acknowledges the nuances of the real world, letting us deal with concepts that aren't always black and white, adding adaptability and responsiveness to our code.

Leveraging Java's Fork/Join Framework for Efficient Parallel Programming: Part 1

Aggregated on: 2024-02-12 19:02:08

In concurrent programming, efficient parallelism is essential for maximizing the performance of applications. Java, being a popular programming language for various domains, provides robust support for parallel programming through its Fork/Join framework. This framework enables developers to write concurrent programs that leverage multicore processors effectively. In this comprehensive guide, we'll delve into the intricacies of the Fork/Join framework, explore its underlying principles, and provide practical examples to demonstrate its usage. Key Components ForkJoinPool: The central component of the Fork/Join Framework is ForkJoinPool, which manages a pool of worker threads responsible for executing tasks. It automatically scales the number of threads based on the available processors, optimizing resource utilization. ForkJoinTask: ForkJoinTaskis an abstract class representing a task that can be executed asynchronously. It provides two main subclasses: RecursiveTask: Used for tasks that return a result RecursiveAction: Used for tasks that don't return a result (i.e., void tasks) ForkJoinWorkerThread: This class represents worker threads within the ForkJoinPool. It provides hooks for customization, allowing developers to define thread-specific behavior. Deep Dive Into Fork/Join Workflow Task partitioning: When a task is submitted to the ForkJoinPool, it's initially executed sequentially until a certain threshold is reached. Beyond this threshold, the task is recursively split into smaller subtasks, which are distributed among the worker threads. Task execution: Worker threads execute the subtasks assigned to them in parallel. If a thread encounters a subtask marked for further division (i.e., "forked"), it splits the task and submits the subtasks to the pool. Result aggregation: Once the subtasks complete their execution, their results are combined to produce the final result. This process continues recursively until all subtasks are completed, and the final result is obtained. Take, for instance, a task designed to calculate the sum of values in an integer array. For small arrays, the task computes the sum directly. For larger arrays, it splits the array and assigns the subarrays to new tasks, which are then executed in parallel.

The Cost-Benefit Analysis of Unit, Integration, and E2E Testing

Aggregated on: 2024-02-09 19:02:06

In software testing, the goal is to balance thoroughness with manageability. Unit testing is efficient and manageable, yet it plateaus in effectiveness beyond 70% coverage, a benchmark difficult to achieve in practice. End-to-end (E2E) testing, while comprehensive, becomes increasingly challenging to maintain as software complexity grows, making full coverage impossible. Integration testing is indispensable for ensuring components work together seamlessly, but it also demands more maintenance with software expansion. The key is to strategically combine these testing methods to ensure software quality without overburdening the process, recognizing that more testing doesn't always translate to better outcomes. “Teams always want to reach high E2E coverage but can’t — and they should reach high unit testing coverage but don’t.“

Making Dropwizard Metrics Accessible via CQL in Apache Cassandra

Aggregated on: 2024-02-09 18:02:06

Metrics are a vital part of complex distributed storage systems, such as Apache Cassandra. It's important for an operator and a user to have access to metrics at the OS, JVM, and application levels to have full control over the data that is being processed and to prevent emergencies before they occur. To make metrics accessible, Cassandra heavily relies on the open-source Dropwizard Metrics library, which acts as a skeleton for both metrics representation and storage. Metrics representations are provided as Histogram, Timer, Meter, Gauge, etc. classes for metric types, while storage uses MetricRegistry. The Dropwizard library makes it easy to expose the database internals through various APIs, like JMX or REST, in addition to the sidecar pattern. Apache Casandra has a vibrant ecosystem in this regard, for example, you can write your java-agent to export all data from the registry to the collectd Unix daemon. In conjunction, Cassandra's virtual tables, which are a relatively recent development by the project's standards (available since 4.0), have only a fraction of all the metrics so far, so don't give a full view of internal processes and need to be improved to rectify this.

Five Java Developer Must-Haves for Ultra-Fast Startup Solutions

Aggregated on: 2024-02-09 13:17:06

Many solutions that promise ultra-fast startup times for serverless Java apps force you to compromise on developer experience, throughput performance, or security. We’ll show you how to get ultra-fast startup of your Java apps without these compromises. Say, for example, you’re writing a Java web service that provides a catalog of items that your business sells. At quiet times, your application needs to stop all unneeded instances of the catalog service so that your business is not paying unnecessary cloud bills; at busy times, your application needs to rapidly spin up more instances so that your customers get instantaneous response times on your website. This is “scale-to-zero,” and your application needs to do it fast.

In the modern software development landscape, data reigns supreme. Product decisions are driven by customer feedback, analytics rule the roadmap, and ideas face endless validation before seeing the light of day. But are we sacrificing creativity in the quest to remove intuition and guessing from the equation? Buildkite's CEO Keith Pitt believes we just might be. While data and metrics fuel today's development, Pitt argues that breakthrough products don't spring from spreadsheets. "Innovation does not come from focus groups," he asserts. "Customers aren't good at ideation."

REST Gateway for a gRPC Service, Part 2

Aggregated on: 2024-02-08 20:32:05

As a quick recap, in Part 1: We built a simple gRPC service for managing topics and messages in a chat service (like a very simple version of Zulip, Slack, or Teams). gRPC provided a very easy way to represent the services and operations of this app. We were able to serve (a very rudimentary implementation) from localhost on an arbitrary port (9000 by default) on a custom TCP protocol. We were able to call the methods on these services both via a CLI utility (grpc_cli) as well as through generated clients (via tests). The advantage of this approach is that any app/site/service can access this running server via a client (we could also generate JS or Swift or Java clients to make these calls in the respective environments).
