📌 Technical Origin of OpenML - A Quantum Physics Problem
The conceptual foundation of OpenML dates all the way back to 2013 when a college boy in Physics major was
reading and implementing the Matrix Numerov Method for Solving Schrödinger Equation

Extensibility Ecosystems
Systems such as ChatGPT Plugins and Gemini Extensions
allows OpenAI and Gemini to connect to external apps and services to retrieve real-time information and perform actions,
allowing them to interact directly with Google Workspace (Docs, Drive, Gmail), Google Maps, Google Flights, Google
Hotels, and YouTube.

Why is AI Deeply-Seated with Philosophy and Language?
AI is not just a consumer of linguistic data; it is a producer of new philosophical questions. It forces us to be more
precise about what we mean by "meaning," "understanding," and "thought," turning centuries of abstract debate into a
pressing, practical challenge.

KV Cache
2026-07-15
Specifically created to solve the massive memory bottleneck and inefficiency of serving Large Language Models in
production, vLLM at its core resolves the problem of LLM serving and inferencing. Before vLLM, the bottleneck in
serving LLMs wasn't just the model weights themselves, but the KV Cache (Key-Value Cache) - the memory required to
store the attention context for generating tokens sequentially. This posts helps us systematically learn KV cache.

MQTT Essentials
2026-06-28
In the rapidly evolving landscape of IoT, MQTT has emerged as the de facto standard protocol for data exchange. This
post on MQTT is designed to equip decision-makers, solution architects, and IoT professionals with a strategic and
practical understanding of MQTT and how to execute it for scalable, reliable, and seamless data movement. Delve into
how MQTT can help organization overcome the challenges other IoT protocols cannot address with features such as
persistent sessions, retained messages, Last Will and Testament (LWT), Quality of Service (QoS) levels, and more.
After reading this guide, you'll be ready to use MQTT to optimize connectivity and lay the proper data foundation to
enable any IoT or IIoT use case.

Introduction to Audio Data
2026-06-19
In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common
example is the conversion of a sound wave to a sequence of “samples”. A sample is a value of the signal at a point
in time and/or space; this definition differs from the term’s usage in statistics, which refers to a set of such values

OpenML's backend Tech Explained
2026-06-06
In this post, we explore the core architectural philosophy behind OpenML's backend infrastructure: a deliberate choice
of explicit control and standards compliance over framework magic. By anchoring our microservices to the strict rules
of the JAX-RS specification, and leveraging precise engines like Jersey and Quarkus rather than comprehensive
ecosystems like Spring, we ensure our codebase remains portable and maintain absolute sovereignty over our entire
execution environment.

Codebase RAG for Coding Agent
We are all familiar with RAG system as a customized LLM trained with private data. How about applying a codebase as
