Deploy TensorRT-LLM on NVIDIA H100 & RTX 6000 — Step-by-Step Tutorial

The demand for fast, affordable Large Language Model (LLM) inference is at an all-time high. Every additional millisecond of latency and every extra dollar per million tokens directly impacts product economics. To maximize throughput and lower costs, enterprise infrastructure teams are standardizing on the two most proven, scalable, and immediately available GPU architectures on the market: the NV...

The "Minimum Viable System": How to Ship Early Without Shipping Junk

There is a dangerous piece of advice in software development: "Just build an MVP." It sounds reasonable. Build the smallest possible version. Launch quickly. Get feedback. Improve later. The problem is that many developers interpret "minimum viable product" as: Remove everything. Skip architecture. Ignore security. Ignore testing. Hardcode everything. Ship it. Then six months lat...

6 Sports Fan Engagement Companies Worth Watching in 2026

Sports fan engagement has a software problem. Most clubs don't lack digital tools. They have too many of them. Memberships live in one system. Ticketing lives somewhere else. Payments are handled separately. Match-day engagement might be another app. Fan communication is often disconnected from all of it. That creates a strange situation: clubs can have more digital touchpoints than ever while ...

One Database Can't Hold Everything: Learn Database Sharding

This is Part 9 of my "From One User to One Million" series, where we'll build an understanding of System Design by following a simple application as it grows from a single user to millions. Instead of memorising technologies, we'll learn why they exist by solving real problems as they appear. Look at what we've built so far. We started with a single server. We added more application servers wh...

LINE Service Messages vs Messaging API: Choose the Right Message Path

LINE MINI App Service Messages and the LINE Messaging API can both deliver messages to users, but they solve different problems. A Service Message confirms or follows up on an action completed inside a LINE MINI App. A Messaging API message comes from a LINE Official Account and supports conversations, direct outreach, and audience messaging. They differ in: Sender identity Trigger Recipient m...

How asyncio Really Works Under the Hood

Python's asyncio is usually introduced through its public API: define a coroutine with async def, suspend it with await, and run several operations concurrently with create_task() or gather(). That is enough to write useful programs, but it does not explain why those programs behave as they do. The difficult questions sit below the API: Why does one blocking function stall every coroutine on th...

One skill per action looked like the safe boundary

I've been building an AI-assisted editorial pipeline in Cursor. Notion cards capture observations, skills score and schedule them, and agents draft markdown that eventually syncs to dev.to. In that setup, a skill is a markdown file the agent loads when you invoke a workflow: it defines what the agent may do, what it must not do, and how it routes between sub-steps. When I started, that model felt...

Why Context Engineering Is More Important Than Prompt Engineering

For the past few years, prompt engineering has been one of the hottest topics in AI. Countless tutorials have promised the "perfect prompt." Courses have been built around writing better prompts. Developers have spent hours refining wording to squeeze better responses from large language models. But after building AI systems across multiple projects, I think the conversation is changing. Prom...

Demystifying the Factory Method Design Pattern in Java

Introduction In software development, creating objects can become complicated when a program needs to work with different types of objects. If object creation logic is written directly throughout the application, the code can become tightly coupled and difficult to maintain. The Factory Method Design Pattern provides a solution to this problem. It is a creational design pattern that defines a me...

Cursor vs Claude Code: Which Wins for Laravel Devs?

Quick answer: In the Claude Code vs Cursor debate, Claude Code wins for Laravel developers who delegate large tasks — multi-file refactors, building a full module, upgrading Eloquent relationships across a codebase. Cursor wins for developers who stay hands-on — writing Blade views, tweaking Livewire components, and reviewing every diff inline. Most Laravel teams in 2026 run both. And for Laravel-...

Accessibility Audit: A Practical WordPress Plugin for Finding WCAG Issues Before Your Visitors Do

Web accessibility is no longer something website owners can afford to treat as an optional enhancement. An inaccessible website can prevent people from reading content, completing a purchase, submitting a form, or even understanding what a button is supposed to do. At the same time, regulations such as the European Accessibility Act have made digital accessibility increasingly relevant for busine...
