Hey there, fellow engineers and tech enthusiasts! I’m excited to share one of my favorite strategies for modern software delivery: combining Docker and Jenkins to power up your CI/CD pipelines. Throughout my career as a Senior DevOps Engineer and Docker Captain, I’ve found that these two tools can drastically streamline releases, reduce environment-related headaches, and give teams the confidence they need to ship faster. In this post, I’ll walk you through what Docker and Jenkins are, why they pair perfectly, and how you can build and maintain efficient pipelines. My goal is to help you feel right at home when…

In a strategic move that could reshape the economics of artificial intelligence (AI) development, Chinese AI startup DeepSeek introduced discounted off-peak pricing for developers looking to use its AI models. This pricing strategy could pressure competitors in China and internationally to reduce their rates.The Hangzhou-based company, which grabbed global attention in January when its R1 model triggered a $1 trillion-plus sell-off in global equities markets, continues challenging established players with innovative business approaches. DeepSeek’s latest pricing model allows developers to access its powerful AI capabilities at reduced rates during periods of lower demand, optimizing infrastructure utilization and developer costs.“This is…
Nearly half (45%) of developers say they don’t have enough time for learning and development, according to a developer experience research study by Harness and Wakefield Research. Additionally, developer onboarding is a slow and painful process, with 71% of executive buyers saying that onboarding new developers takes at least two months. To accelerate innovation and bring products to market faster, organizations must empower developers with robust support and intuitive guardrails, enabling them to succeed within a structured yet flexible environment. That’s where Docker fits in: We help developers onboard quickly and help organizations set up the right guardrails to give…
F5 has introduced the F5 Application Delivery and Security Platform, the industry’s first ADC 3.0 solution that converges high-performance load balancing and traffic management with advanced app and API security capabilities into a single platform. The announcement, made during the keynote at F5 AppWorld 2025, addresses the growing complexity of application delivery in hybrid, multi-cloud and increasingly AI-powered environments.The Evolution to ADC 3.0François Locoh-Donou, F5’s President and CEO, described how application delivery has evolved through three distinct phases: ADC 1.0 (hardware appliances in on-premises data centers), ADC 2.0 (cloud-native services) and now ADC 3.0 – a comprehensive platform approach designed…
Docker simplifies containerization by removing runtime complexity and making app development seamless. With Docker Engine v28, we’re taking another step forward in security by ensuring containers aren’t unintentionally accessible from local networks. This update isn’t about fixing a single vulnerability — it’s about security hardening so your containers stay safe. What happened? When you run a container on the default Docker “bridge” network, Docker sets up NAT (Network Address Translation) rules using your system’s firewall (via iptables). For example, the following command forwards traffic from port 8080 on your host to port 80 in the container. docker run -d -p…
I grabbed this book over the 2024 holiday season as it was on sale and recommended by the DevOps practitioners over at ITRevolution.A Radical Enterprise looks at a new way of building organizations, actually a few way, where the power and decisions are decentralized.I am pretty open to trying new things and experimenting, but I was very skeptical this would work in many places as I started this book and remain so after finishing it. I kept thinking this felt like a feel-good, kumbaya approach to running an organization. Giving responsibility, devolving it from management to individual teams and having…
Linux is a powerful and reliable operating system, but even seasoned users encounter unexpected problems. Whether it’s a deleted file, a forgotten root password, or a sluggish system, knowing how to troubleshoot efficiently is key to becoming a true Linux expert. This guide presents real-world Linux problem-solving scenarios along with step-by-step solutions, which are common among system administrators, developers, and everyday Linux users. Scenario 1: You Accidentally Deleted an Important File You accidentally deleted an important file using the rm command, and now you need to recover it. Unlike Windows and macOS, Linux does not have a built-in “Recycle Bin”…
Generative AI, a subset of AI, is a new technology that can create content in different forms, such as text, images and videos. Integrating generative AI into DevOps practices can benefit an organization’s business processes. This article addresses the advantages, obstacles and opportunities concerning blending and integrating generative AI with DevOps. Understanding the Problem Organizations can benefit from efficiently managing their IT resources according to their management goals. However, the challenge lies in integrating new technologies into their business processes. Business owners face a daunting challenge when they receive customer complaints about issues that arise. As a result, these problems can only…
I’ve created countless security tools over my years in cybersecurity, but few match the raw power and simplicity of a well-crafted keylogger. Let me show you how to build one in just 10 lines of Python code.A keylogger captures every keystroke a user makes. While legitimate applications exist for monitoring activity, I must emphasize this guide is strictly educational. Unauthorized keylogging is illegal and unethical.A Python keylogger requires just 10 lines of code using the pynput library to capture keystrokes and the logging module to record them to a file. This minimal code creates a powerful monitoring tool that can…
Textual v0.80.0 was released today, and it included the brand-new MaskedInput widget. If you have used other GUI toolkits, such as wxPython, you might already be familiar with a masked input widget. These widgets allow you to control the user’s input based on a mask string that the developer provides when instantiating the widget. Let’s spend a few brief moments learning how this new widget works. Getting the Latest Textual Before you can use the MaskedInput widget, you must ensure you have version 0.80.0 or greater. If you have an older version, then you’ll need to upgrade by running the following…
