Several years ago, I created an XML editor with the wxPython GUI toolkit called Boomslang. I recently thought it would be fun to port that code to Textual so I could have an XML viewer and editor in my terminal as well. In this article, you will learn how that experiment went and see the results. Here is a quick outline of what you will cover: Get the packages you will need Create the main UI Creating the edit XML screen The add node screen Adding an XML preview screen Creating file browser and warning screens Creating the file save…

Linux users often need to use one command over and over again. Typing or copying the same command over and over again reduces your productivity and distracts you from what you are supposed to be doing. You can save yourself some time by creating aliases for your most commonly used commands. Aliases are like custom shortcuts that represent a command (or set of commands) that can be executed with or without custom options. Chances are you are already using aliases on your Linux system without even knowing it. List Currently Defined Aliases in Linux You can see a list of…

In our recent report, we describe that many enterprises today face a stark reality: despite years of digital transformation efforts, the majority of enterprise workloads—up to 80%—still run on legacy systems. This lag in modernization not only increases operational costs and security risks but also limits the agility needed to compete in a rapidly evolving market. The pressure is on for technology leaders to accelerate the ongoing modernization of legacy applications and to accelerate cloud adoption, but the path forward is often blocked by technical complexity, risk, and resource constraints. Full Report: Accelerate Modernization with Docker.Enterprises have long been treating…
Let us be honest; most database upgrades feel like a patchwork of performance tweaks and security updates. But SQL Server 2025? It is not just an upgrade. It is a redefinition of what a database can be in the age of AI, real-time analytics, and hybrid cloud ecosystems.I did not approach this release like a checklist. I approached it like a challenge: What if your database can think faster, search smarter, and connect deeper; without rewriting your entire stack?Here is what I found:Vector Search: SQL Meets SemanticsForget keyword matching. SQL Server 2025 introduces native vector data types and Approximate Nearest…
The future arrived quietly this month, but not in the way we hoped. While developers worldwide were busy leveraging AI to write code faster and solve problems more efficiently, a malicious actor was demonstrating just how easily our AI assistants could turn against us.Amazon’s Q Developer Extension for Visual Studio Code, a tool trusted by nearly a million developers, briefly became a potential weapon of mass digital destruction. The incident, quietly disclosed in AWS Security Bulletin AWS-2025-015, represents more than just a security hiccup. It’s a glimpse into a new category of cyberthreats that should fundamentally change how we think…
File Transfer Protocol (FTP) was once a widely used method for transferring files or data remotely. However, it transmits information in an unencrypted format, making it an insecure way to communicate. As we all know, FTP is not secure because all transmissions occur in clear text, which means that anyone sniffing network packets can easily read the data. Because of this, FTP should only be used in limited cases or on networks you fully trust. Over time, protocols like SCP (Secure Copy) and SSH (Secure Shell) have addressed these security concerns by introducing encrypted layers for securely transferring data between…
As a software Engineer, I would like to deploy my Dockerized Python Application to Azure Container Instance (ACI) using Azure DevOps so that I can automate my workflow and eliminate any manual intervention during the deployment.In this blog post, I will walk you through how to build and deploy a Dockerized Python Application to Azure Container Instances (ACI) using Azure DevOps. The workflow will build and deploy the docker image to Azure Container Registry (ACR), and finally, the application will be deployed to Azure Container Instances.What is Azure? Azure is a cloud computing platform and services, provided by Microsoft. It…
