Building Realistic Test Data in Java: A Hands-On Guide for Developers
Thereβs something that every backend or API developer faces sooner or later: the need for good fake data. Whether youβre testing a new API, populating a database for demos, or simply trying to make your unit tests less βboringβ, fake data is part of your daily routine. The problem? Most fake data feelsβ¦ fake. You end up with βJohn Doeβ and β123 Main Streetβ repeated over and over, which doesnβt look great when showing...
Securing HTTPS From the Inside Out: Preventing Client-Side Interception Attacks
Overview HTTPS is the most common mechanism used to protect client-server communication on the internet. Most teams focus on SSL/TLS and server-side hardening β and for good reason β but security is layered: the system is only as strong as its weakest link. This article focuses on a specific class of HTTPS man-in-the-middle (MITM) attacks that is not widely discussed. The aim is to harden one of the weaker links in...

Popular DevOps Automation Tools
DevOps automation tools streamline the path from idea to deployment by turning repetitive, error-prone steps into reliable, repeatable workflows that reduce toil and shorten mean time to recovery (MTTR). This article walks through five categories of DevOps automation tools. Expanding your tool stack thoughtfully is less about quantity and more about reducing change failure rate and increasing deployment frequency in a...
Using LLMs to Automate Root Cause Analysis in Incident Response
Executive Summary In todayβs complex cloud and microservices-based systems, itβs no surprise that things break. While weβve made huge strides in detecting issues quickly with modern observability tools, getting to the actual root of a problem β what really caused the incident β is still a tough, manual, and time-consuming task. Thatβs where large language models (LLMs) step in. These AI models are trained to understand...
Evaluating LLM-Powered Voice Assistants: A Guide Beyond Traditional Metrics
Voice assistants have evolved from being simple, rule-based systems to advanced conversational agents driven by large language models (LLMs). Early versions of voice assistants could only handle specific tasks with pre-defined commands. In contrast, modern LLM-powered assistants can now engage in long and open-ended conversations, follow complex instructions, and perform multi-step reasoning. These improved...

412: 2.0 Embedded Pens
Or just βEmbedsβ as we more frequently refer to them as. Stephen and Chris talk about the fairly meaty project which was re-writing our Embeds for a CodePen 2.0 world. No longer can we assume Pens are just one HTML, CSS, and JavaScript βfileβ, so they needed a bit of a redesign, but doing as [β¦]
Copper-Engine: a new 3D game engine made to empower indie Devs around the world

As stated previously, one of our core...
How GenAI Can Eliminate SME Bottlenecks in Enterprise Systems
In large-scale enterprises, tribal knowledge often stalls developer productivity and slows operational agility. Subject matter experts (SMEs) become bottlenecks when critical business logic and configuration decisions live only in legacy codebases or in the minds of a few veterans. This article presents an architecture that leverages GraphCodeBERT embeddings, FAISS vector search, and large language models (LLMs) like...

Theia Deep Dive, Part 2: Mastering Customization
In the first part, we set up the basics: Theia runs in the browser, plugins work, themes and icons load, and we even added a splash screen. That gives us a functional IDE, but itβs still pretty close to stock. This part is about shaping it into our own product. Weβll start by stripping out what we donβt need, then adjust the UI and wire up contributions so the editor feels focused and intentional.
