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...

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...

This time, there was no project team, no IT budget, and no stakeholder meetings. Just me β and the need...
Who watches the watchers? LLM on LLM evaluations
While using LLMs to judge LLM outputs might seem like the fox guarding the henhouse, turns out it works pretty well (and scales better than humans).
Virtualization Meets Acceleration: Powering AI Workloads
Artificial Intelligence has quickly moved from buzzword to business driver. From chatbots and fraud detection to medical imaging and predictive analytics, AI has found a home in nearly every industry. But as AI evolves, so do the infrastructure demands that support it. Training large models or running real-time inference pipelines isnβt trivial β it takes serious compute, bandwidth, and orchestration. Hereβs the good...
Keeping my Nix inputs fresh

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.

The Top 20 Problems With Batch Processing (and How to Fix Them With Data Streaming)
Batch processing has long been the default approach for moving and transforming data in enterprise systems. It works on fixed schedules, processes data in large chunks, and often relies on complex chains of jobs that run overnight. While this was acceptable in the past, todayβs digital businesses operate in real time β and canβt afford to wait hours for fresh insights. Delays, errors, and inconsistencies caused by...
