Using Zero-Width Assertions in Regular Expressions

Aggregated on: 2024-07-08 21:23:22

Anchors ^ $ \b \A \Z Anchors in regular expressions allow you to specify the context in a string where your pattern should be matched. There are several types of anchors: ^ matches the start of a line (in multiline mode) or the start of the string (by default). $ matches the end of a line (in multiline mode) or the end of the string (by default). \A matches the start of the string. \Z or \z matches the end of the string. \b matches a word boundary (before the first letter of a word or after the last letter of a word). \B matches a position that is not a word boundary (between two letters or between two non-letter characters). These anchors are supported in Java, PHP, Python, Ruby, C#, and Go. In JavaScript, \A and \Z are not supported, but you can use ^ and $ instead of them; just remember to keep the multiline mode disabled.

Test Smells: Cleaning up Unit Tests

Aggregated on: 2024-07-08 21:23:22

In practical terms, knowing how not to write code might be as important as knowing how to write it. This goes for test code, too; and today, we're going to look at common mistakes that happen when writing unit tests. Although writing unit tests is common practice for programmers, tests are still often treated as second-class code. Writing good tests isn't easy — just as in any programming field, there are patterns and anti-patterns. There are some really helpful chapters on test smells in Gerard Meszaros's book about xUnit patterns — and more great stuff around the internet; however, it's always helpful to have practical examples.

AWS: Metric Filter vs. Subscription Filter

Aggregated on: 2024-07-08 21:23:22

In this blog on AWS, let’s do a comparison study between two filter tools available with Amazon CloudWatch Logs — Metric Filter and Subscription Filter, which play a crucial role in log data management, allowing you to analyze, monitor, and act on log data effectively. Metric Filter Metric Filters define the terms and patterns to look for in log data as it is sent to CloudWatch Logs. CloudWatch Logs uses these metric filters to turn log data into numerical CloudWatch metrics that you can graph or set an alarm on. For eg., you can create a metric to count the occurrences of the word “ERROR” in your logs & set an alarm if the count goes beyond a certain threshold.

Real-Time Testing: Best Practices Guide

Aggregated on: 2024-07-08 21:23:22

Real-time testing is a crucial part of the Software Development Life Cycle that involves testing software applications for their reliability and functionality in real-time. This involves simulating the real-time environment or scenarios to verify the performance of the software application under various load conditions. Due to this, real-time testing has become one of the major aspects of software testing. It has been popularized based on its ability to test the software application in its operational mode. In this fast-growing software industry, organizations struggle to maintain the pace of software application development and its release. In this process, testing application quality, performance, and functionality is the priority phase which helps ensure end-user requirements are fulfilled. However, software testing is a vast domain, and software applications have to undergo various stages of testing that vary from functional to non-functional testing as per software application requirements.

Enhancing Cloud Security: Integrating DevSecOps Practices Into Monitoring

Aggregated on: 2024-07-08 21:23:22

In the fast-changing world of tech, companies must get their apps out quickly but can't forget to keep them safe. Gone are the days when security checks happened only after making the app. Now, there's an intelligent way called DevSecOps that ties together software development lifecycle, security, and operations into one smooth process. Prolific DevSecOps practices ensure safety measures are part of every step in getting an app from idea to user's hands through continuous integration (CI) and delivery (CD), covering everything before launch and after it goes live. DevSecOps isn't just a fad; it marks a significant change in the overall production environment and in how people think about building and sending out software. By weaving security into each phase of app development cycle, devsecops teams can release secure software quicker than ever. They're better at finding and fixing security flaws early on, enhancing the traditional software development cycle and staying on top of legal rules for protecting data.

Aggregated on: 2024-07-08 21:23:22

Have you ever come across a situation in automated API testing where you were not able to identify the issue in the test failure and after debugging for multiple hours, you noticed that the data type of the value supplied in the response of the API had changed. Did you then notice that this was the core reason for the test failure? This type of scenario can generally happen when you have third-party APIs integrated into your application. A real-time example of such a scenario would be integrating with the Bank APIs for making a payment for your e-commerce application or integrating with third-party API which provides the registration and login functionality using two-factor authentication.

Understanding and Mitigating IP Spoofing Attacks

Aggregated on: 2024-07-08 21:23:22

Spoofing is a type of cyber-attack used by hackers to gain unauthorized access to a computer or a network, IP spoofing is the most common type of spoofing out of the other spoofing method. With IP Spoofing the attacker can hide the true source of the IP packets to make it difficult to know the origin of the attack. Once access to a network or a device/host is achieved, cybercriminals usually mine them for sensitive data, with computers they can turn into zombies and can be used to launch Denial-of-Service (DoS) attacks. What Is IP Spoofing? IP addresses are used for communication between devices on the internet. Cybercriminals use a false source IP address to hide and impersonate another system. Essentially making it harder for the destination system to detect. Such attacks come with the intent to steal sensitive data, infect your computer with malware or viruses, or even crash your server.

In this article, I will discuss how you can apply the Pareto principle to quickly learn a new programming language and start solving real-world problems while you develop a deeper understanding of the programming language. What Is the Pareto Principle? The Pareto principle, also known as the 80/20 rule, states that for many outcomes, roughly 80% of consequences come from 20% of causes. Applying this to a personal level, 80% of your work-related output could come from only 20% of your time. I first came to know about this principle after reading the book "The 80/20 Principle: The Secret to Achieving More with Less" written by Richard Koch.

How To Remove Excel Worksheets Using APIs in Java

Aggregated on: 2024-07-05 14:38:20

Manipulating Excel documents with code is more than just a value-add process in many environments. It’s often a necessity, eliminating the manpower that would otherwise be committed to the monotonous task of adjusting large and complex spreadsheets in a predictable, cyclical way. Thanks to various open-source libraries (like Apache POI, for example), programmatically creating, manipulating, and deleting Excel data is reasonably straightforward for experienced developers. Libraries like these provide a layer of abstraction between the developer and the behind-the-scenes “button-pressing” required to make XLSX (open office Excel) files perform actions akin to what we might accomplish with points and clicks in the Excel application.

Packages for Store Routines in MariaDB 11.4

Aggregated on: 2024-07-05 00:53:20

MariaDB 11.4 introduced many advanced features. One that grabbed my attention is the general support of packages for stored routines. Although this was previously available by activating the Oracle compatibility mode, now the feature is available generally out-of-the-box. This will help you to significantly enhance the organization of database development within a MariaDB environment. Packages provide a modular approach to managing database logic. This addition aligns MariaDB more closely with other advanced database systems that have long utilized packages, such as Oracle, and sets it apart in that regard from other open-source relational databases that don’t support packages. Packages in MariaDB allow you to group related stored procedures, functions, variables, and other elements together into a single unit. This structure provides several benefits, including improved code organization, enhanced reusability, and simplified maintenance. Prior to this update, each stored procedure and function in MariaDB existed independently, which could lead to a cluttered schema and more complicated management of complex business logic when implemented in the database. Packages address this issue by providing a way to logically group related routines.

At its current state, Generative AI can be useful in certain scenarios, but it’s far from being the be-all and end-all that was promised or imagined. The cost and expertise required to evaluate, develop, and deploy Generative AI-powered applications remains substantial.

Maintain Chat History in Generative AI Apps With Valkey

Aggregated on: 2024-07-04 22:53:20

A while back I wrote up a blog post on how to use Redis as a chat history component with LangChain. Since LangChain already had Redis chat history available as a component, it was quite convenient to write a client application. But, that's not the same with langchaingo which is a Go port of LangChain. I am going to walk through how to do the same, but for Valkey (not Redis). Valkey is an open-source alternative to Redis. It's a community-driven, Linux Foundation project created to keep the project available for use and distribution under the open-source Berkeley Software Distribution (BSD) three-clause license after the Redis license changes.

Building an Effective Zero Trust Security Strategy for End-To-End Cyber Risk Management

Aggregated on: 2024-07-04 21:08:19

You've probably heard a lot about zero-trust security lately, and for good reason. As we move more of our applications and data to the cloud, the traditional castle-and-moat approach to security just doesn't cut it anymore. This makes me come to the realization that we can no longer have a "trust but verify" approach, assuming everything behind the corporate firewall is safe. "Never trust. Always verify." Now that’s the stance we need to take going forward.

Flask Web Application for Smart Honeypot Deployment Using Reinforcement Learning

Aggregated on: 2024-07-03 23:08:20

Honeypots are the digital traps used by cybersecurity professionals to lure in attackers. These traps imitate real systems and services, such as web servers or IoT devices, to appear as genuine targets. The goal of a honeypot is to deceive attackers into interacting with them, enabling security experts to observe and analyze their behavior. Challenge and Proposed Solution Traditional honeypots have limitations as they can be easily identified by skilled attackers and struggle to adapt to new threats. By applying RL, we can develop a smart honeypot deployment system that learns and adapts to emerging threats in real time. Imagine a cybersecurity team using a Reinforcement Learning-driven honeypot to combat phishing attacks. The honeypot monitors incoming emails and adjusts its responses based on the perceived threat level of each email. Over time, it learns to identify phishing attempts more effectively and assists the team in understanding how attackers alter their tactics.

Organizations typically use the lead assignment rule and case assignment rule to automatically assign new leads or cases to the users or queue. When we create leads or cases from MuleSoft using the Salesforce connector, by default it does not trigger the assignment rules and does not send email notifications to owners.

An Effective Way To Start a NextJS Project

Aggregated on: 2024-07-03 00:53:18

Choosing a framework for starting a new project can be quite challenging, considering the many frameworks and tools available today. Developers who want to build high-performance and scalable web applications often choose Next.js over others. No wonder, since Next.js is a React framework created by Vercel, offers a comprehensive solution for building server-side rendered (SSR) and static web applications. Here are some of the key advantages: Server-Side Rendering (SSR) and Static Site Generation (SSG): Next.js supports both SSR and SSG, allowing developers to choose the best rendering method for their needs. SSR improves SEO and page load speed by rendering pages on the server, while SSG can pre-render pages at build time for faster performance. Built-in routing: Next.js simplifies routing with its file-based routing system. By organizing your files and folders in the pages directory, you can automatically create corresponding routes, eliminating the need for an external router library. Optimized performance: Next.js comes with a host of performance optimizations out of the box, including code splitting, automatic static optimization, and image optimization, ensuring your application runs efficiently. Starting from scratch can be time-consuming, especially when configuring essential features like authorization and CRUD operations. A proper approach is to use a ready-made boilerplate that includes these settings, allowing you to focus on building features rather than setting up the basics. By applying a ready-to-use Next.js boilerplate, you would get:

How to Configure Custom Metrics in AWS Elastic Beanstalk Using Memory Metrics Example

Aggregated on: 2024-07-02 21:08:18

Recently, I encountered a task where a business was using AWS Elastic Beanstalk but was struggling to understand the system state due to the lack of comprehensive metrics in CloudWatch. By default, CloudWatch only provides a few basic metrics such as CPU and Networks. However, it’s worth noting that Memory and Disk metrics are not included in the default metric collection. Fortunately, each Elastic Beanstalk virtual machine (VM) comes with a CloudWatch agent that can be easily configured to collect additional metrics. For example, if you need information about VM memory consumption, which AWS does not provide out of the box, you can configure the CloudWatch agent to collect this data. This can greatly enhance your visibility into the performance and health of your Elastic Beanstalk environment, allowing you to make informed decisions and optimize your application’s performance.

Performance and Scalability Analysis of Redis and Memcached

Aggregated on: 2024-07-02 21:08:18

Speed and scalability are significant issues today, at least in the application landscape. Among the critical enablers for fast data access implementation within in-memory data stores are the game changers in recent times, which are technologies like Redis and Memcached. However, the question arises of choosing the best one. This article takes a plunge into the comparative analysis of these two cult technologies, highlights the critical performance metrics concerning scalability considerations, and, through real-world use cases, gives you the clarity to confidently make an informed decision. We have run these benchmarks on the AWS EC2 instances and designed a custom dataset to make it as close as possible to real application use cases. We compare throughput, operations per second, and latency under different loads, namely the P90 and P99 percentiles. We investigate deeper in a clustered environment and try identifying the scalability characteristics of both Redis and Memcached, including the implementation and management complexities of either. This level of comparison detail will assist decision-makers with the information they would need to make a more appropriate choice of an in-memory data store for their needs.
