Docker, Inc.®, a provider of cloud-native and AI-native development tools, infrastructure, and services, today announced the acquisition of MCP Defender, a company founded to secure AI applications. The rapid evolution of AI-from simple generative models to powerful agentic tools-has transformed software development in extraordinary ways. But as with all powerful technologies, new capabilities bring new security challenges. We recently highlighted critical MCP security issues on the Docker blog, emphasizing how essential it is to secure our emerging AI infrastructure. Building on that discussion, we want to offer our perspective on the current state of AI security, outline its trajectory, consider…

When working on a Linux system, every command you run returns a status code (also called an exit status or return code) that tells you whether it ran successfully or failed. As a Linux user, especially if you’re learning shell scripting or troubleshooting, knowing how to check the exit status of a command is super important. In this article, I’ll explain what exit status means, how to check it, and why it matters. What is Exit Status in Linux? Whenever you run a command in Linux, the system quietly gives it a scorecard at the end, which is just a…
In today’s digital-first and cloud-native world, observability is beyond collecting metrics, logs, and traces and this action must be eligible, directly driving business results. Observability empowers organizations to quickly detect and resolve issues, customize user experience and align IT operations with broader business goals. In this blog, we will find out how to make observability efficiency really impressive for the success of business, illustrated with solid numbers and examples from the real world. What Does it Mean to Make Observability Actionable? Traditional monitoring often answers “what happened” but not “why” or “how it impacts the business.” Actionable observability means: Connecting technical data with…
DNS (Domain Name System) is a fundamental facilitator of several networking technologies such as mail servers, Internet browsing, and streaming services e.g., Netflix and Spotify, among others. It works on a special computer called a DNS server – which keeps a database record of several public IP addresses along with their corresponding hostnames for it to resolve or translate hostnames to IP addresses upon user request. This happens so that we would not need to bother ourselves with remembering the IP addresses of the different websites we visit. While there are several things we can discuss on DNS servers, such…
A report published this week by Sonar finds the GPT-5 platform released by OpenAI has the potential to generate better code but at significantly higher costs.Based on over 4,400 Java tasks, the report finds that depending on which of the four levels of reasoning capabilities that OpenAI now makes available, the overall quality of the code, especially in terms of the vulnerabilities generated, significantly improves.However, the overall volume of code being generated per task also substantially increases, which creates additional maintenance challenges for application developers that are not going to be familiar with how code might have been constructed in…
If you’re new to Python, you probably just want your scripts to work without crashing. That’s cool, but working code isn’t the whole story. It needs to stay secure too. A buggy program bugs you, sure, but one that spills secrets or invites hackers? That’s real trouble.Big firms aren’t the only ones at risk with security stuff. Your little apps or fun projects can get hit if they connect online, manage sign-ins, or hold personal details. Start thinking secure from day one—it saves headaches later.Security goes beyond your scripts, though. Your setup counts a lot. Like, coding on open Wi-Fi?…
Running large AI models in the cloud gives access to immense capabilities, but it doesn’t come for free. The bigger the models, the bigger the bills, and with them, the risk of unexpected costs. Local models flip the equation. They safeguard privacy and keep costs predictable, but their smaller size often limits what you can achieve. For many GenAI applications, like analyzing long documents or running workflows that need a large context, developers face a tradeoff between quality and cost. But there might be a smarter way forward: a hybrid approach that combines the strengths of remote intelligence with local…
It is time once again to share a list of the best free and open-source software I’ve come across in 2025. Some of these programs are long-standing favorites that continue to improve year after year, while others are newer projects that caught my attention and proved useful in my daily Linux workflow. As always, this is not meant to be an exhaustive list, but rather a personal collection of tools that I’ve found reliable, practical, and worth recommending. It is in the spirit of sharing that I’m writing this article, hoping you’ll discover something here that makes your Linux experience…
It always starts the same way. You open your laptop on a Monday morning, coffee in hand, ready to tackle the week, only to spend the first hour hunting for “that one report” you swear was shared last Thursday. You search your inbox, scroll through chat threads, dig through shared drives, and finally find three different versions of the same file, each telling a slightly different story. By the time you figure out which one is current, your coffee is cold, and your patience is gone.That’s the chaos Microsoft Fabric Workspaces were built to end.If you think a Fabric Workspace…
September 2, 2025 by Jenn Yarnold As businesses like yours turn to AI to drive innovation, data has become the strategic lever for agility and growth. Yet for many organizations, the promise of AI remains out of reach because entrenched legacy data systems stand in the way of progress. These aging architectures, characterized by siloed data, technical debt, and a lack of scalability, create significant roadblocks that inhibit innovation and increase costs.
