Programming

Programming has become a practical operations skill for network operations center engineers because modern networks expose APIs, generate structured telemetry, and require repeated changes across large device fleets. NOC analysts do not need to become full-time software developers. It is to make routine investigation, data handling, validation, configuration, and escalation more reliable than a collection of manual copy-and-paste steps. Cisco’s current CCNA Automation path reflects that shift. The 200-901 CCNAAUTO exam covers software development, APIs, application deployment and security, scripting, unit testing, workflow automation, and infrastructure as code. A NOC…

The Evolution of PowerShell PowerShell, initially introduced by Microsoft in 2006, has evolved from a simple task automation tool into a cornerstone of modern IT operations. As an object-oriented scripting language and command-line interface (CLI), PowerShell was designed to replace the traditional command prompt with a more versatile tool capable of handling complex system administration tasks. What started as a way to simplify the management of Windows-based systems quickly gained recognition for its powerful capabilities in automating administrative tasks and managing system configurations. The Beginning: PowerShell’s Initial Role Before PowerShell,…

Introduction to PowerShell: Getting Started The Power of PowerShell “Yeah, I know a little PowerShell” is a phrase often tossed around by seasoned system administrators. Depending on who says it, this statement can mean vastly different things. For some, it’s a humble acknowledgment of having explored basic scripting. For others, it’s an overestimation of their experience, often due to brief exposure or simply having heard the term used in technical conversations. PowerShell is one of the most misunderstood tools in the IT world—widely recognized, but rarely mastered, and often underutilized….

Python certification can be useful in 2026, but its value depends on what problem you are trying to solve. A credential can provide a structured syllabus, a measurable milestone, and third-party evidence that you understand a defined body of Python knowledge. It cannot replace the ability to write, test, debug, explain, and maintain real code. The Python Institute still operates a multi-level certification program. Its general-purpose track currently lists PCEP at entry level, PCAP at associate level, and PCPP1 at professional level as active credentials. The organization has also been…

GitHub Actions can turn network automation from a collection of scripts into a controlled delivery workflow. Instead of asking an engineer to run a local script against production, a repository can define when automation runs, which checks must pass, which secrets or identities are available, who approves a change, and what evidence remains after execution. GitHub’s current certification portfolio includes the GitHub Actions certification, with a direct GitHub Actions exam target in the ExamSnap inventory. The certification is broader than network automation, but workflow, security, artifacts, environments, and troubleshooting concepts…

As a professional working in an environment where automation plays a key role, learning and mastering scripting tools is a fundamental part of your skillset. One such tool is PowerShell, a powerful automation scripting language developed specifically for managing system tasks in a streamlined manner. Though there are many programming languages and automation tools available, PowerShell stands out, particularly for those working with Microsoft technologies. While it might not be superior to every language or tool, like Batch, VBScript, or Python, it is indispensable in environments where Microsoft products are…

The world of programming languages is vast and ever-evolving. With the rapid development of technology, new programming languages continually emerge, challenging established norms and offering fresh approaches to solving problems. Today, there are a plethora of languages used for various purposes, ranging from web development to data science and system programming. However, some of the older, well-established programming languages, such as Java, C, C++, and Python, still dominate the scene. According to various surveys, Java holds the top spot, followed by C, C++, and Python. JavaScript, another well-known programming language,…

There is no single universal “blockchain developer certification” that defines the profession. Providers use different platforms, languages, and exam blueprints, so the safest preparation strategy is to build the smart-contract skills that transfer across credible developer credentials and then map them to the specific exam you plan to take. For Ethereum-compatible development, that usually means understanding Solidity and the EVM deeply enough to explain what a contract will do, what it will cost, how it can fail, and how an attacker might abuse it. Start with state, storage, and execution…

Introduction to Python Python has long been considered one of the most accessible programming languages, both for beginners and experienced developers. Its design philosophy emphasizes simplicity and readability, which allows developers to focus on solving problems rather than grappling with complex syntax. Python’s clean syntax, which closely mirrors human language, makes it an ideal choice for individuals who are just starting their programming journey, as well as for seasoned professionals who need a language that is easy to write and maintain. Python is classified as a high-level, interpreted language, which…

Choosing JavaScript testing tools in 2026 is less about finding one universal framework than about matching a tool to the failure you are trying to prevent. A function that transforms data needs fast, deterministic tests. A React interface needs checks that resemble user interaction. A checkout flow needs real-browser coverage. Trying to solve all three problems with a single tool often produces a slow suite that is difficult to trust. The ten tools below cover different layers of a modern testing strategy. Some execute tests; others provide assertions, browser automation,…

The historical partnership announcement points to a problem that still exists The source article described an ExamSnap Training and Testhouse collaboration aimed at closing a software-testing skills gap. The named courses and tools reflected the era of the announcement, including older Microsoft testing and lifecycle products. The durable issue is more important than the old catalog: organizations still struggle to develop testers who can work inside fast delivery systems rather than only execute manual test cases at the end of a project. A current rehabilitation should therefore preserve the purpose…

JavaScript testing is no longer a choice between one general-purpose test runner and manual browser checks. Modern teams combine fast unit tests, component tests, API checks, end-to-end browser automation, static analysis, and CI feedback. The best toolset is therefore not the longest list of popular names. It is the smallest combination that gives fast feedback at the layers where your application can actually fail. As of 2026, Jest remains a mature general-purpose JavaScript test framework, Vitest is a strong fit for Vite-centered projects, Playwright provides cross-browser end-to-end automation, and Cypress…

Computer science has become one of the biggest fields in the world today, and more people are delving deep into this area every day. There are many avenues that you can explore when you are studying it, but one of the main realms is programming. When you talk about it, one of the key tools that you need to be a part of this field is to know the appropriate programming language. There are a lot of programming languages that you can rely on. However, one of the most popular…

Cloud application development has fundamentally changed how security responsibilities are distributed across the software development lifecycle, shifting many security considerations directly into the hands of developers rather than leaving them solely to dedicated security teams. As organizations increasingly adopt cloud-native architectures, microservices, and continuous deployment pipelines, developers find themselves writing code that directly impacts an application’s security posture in ways that traditional, on-premises development rarely demanded. This shift means cloud app developers can no longer treat security as someone else’s problem, since vulnerabilities introduced during development often surface in production…
