How to Configure Full Parallel Execution in TestNG via Maven (with Dynamic Thread Control)

Running automation test suites sequentially can quickly become a bottleneck in CI/CD pipelines. To optimize execution efficiency, you can enable full parallel execution using TestNG and Maven, allowing you to control thread counts dynamically right from the command line without modifying XML files every time. Here is a step-by-step guide on how to configure your framework for flexible parallel ex...

Put Your Docker Images on a Diet with Alpine Linux (2015)

Archival repost — originally published on my old blog on June 21, 2015, back when Alpine was still a dark-horse pick rather than the default. Already in English, lightly cleaned up for dev.to (fixed a few typos). Alpine did go on to become the mainstream slim-base choice — but it's not the automatic right answer anymore either: its musl libc trips up some native Node/Python modules, and DNS resolu...

From 45 to 70 Free Tools — Toollium Just Got a Lot Bigger

A few weeks ago I shared Toollium here — 45 free browser-based tools with no sign-up, no watermarks, and nothing uploaded to a server. The response pushed me to keep going. Toollium is now at 70 tools, and I want to walk through what's new and why I built it this way. The philosophy hasn't changed Same three rules as before: No sign-up, ever No watermarks on anything you export Files never le...

Technical SEO Checks I Run Before Writing More Content

“We need more content” is one of the most common conclusions in SEO. Sometimes it is right. Often it arrives too early. If search engines cannot reliably crawl, understand or index the pages already on a site, another twenty articles just create a larger pile of URLs with the same problem. Before planning content, I run a technical pass in a fixed order. It is not glamorous, but it stops expens...

I used JSON files instead of a database for 1,699 records. Here's what actually broke.

Three years ago I'd have called this a bad idea. I still might. But I've been running ryzenstudy.com on flat JSON files for months now — 1,699 exam paper records, 699 distinct subject codes, five academic programmes, zero database servers — and the failures haven't been the ones anyone warned me about. Nobody warned me about slugs. The setup It's a Next.js 15 app on App Router, one VPS, PM2 in ...

Agentic AI That Survives the Enterprise, Part 5: Humans in the Loop Without Burning Out Humans

Part 1 ended with a confession: you'll never test your way to 100% correctness. For critical workflows the final safety net is a human. But "human in the loop" has a dirty secret. Badly designed, it's theater. The rubber-stamp problem Route every agent action to a human for approval and watch what happens. Week one, careful reviews. By week three approval fatigue sets in and people cli...

Agentic AI That Survives the Enterprise, Part 4: Boring Engineering Wins

The first three parts covered thesis, cost, and security. This one covers everything that separates a demo from a production system. None of it is exciting. All of it is why some teams sleep at night. The production checklist Trace everything. Langfuse, LangSmith, or OpenTelemetry; pick one and stick with it. When (not if) a workflow misbehaves in production, traces are the difference ...

What Coding Agents Say When They Talk to Each Other

An observational study on a five-day corpus — 179 messages between parallel coding sessions — followed by an experiment built from what the corpus said. Every message was coded twice by independent coders, and disagreements are reported rather than resolved in my favour. One machine, one person, one set of repositories: the ceiling is coverage, not confidence. Claude Code sessions can now messa...

Agentic AI That Survives the Enterprise, Part 3: The Agent With Credentials

Parts 1 and 2 covered reliability and cost. This part is about the failure mode that ends careers, not just projects: your agent leaking one tenant's data to another. Here's what changes when you give an LLM access to tools and data. Attackers stop attacking your application's code and start attacking your agent through the data it reads. A poisoned invoice, a malicious resume, a crafted support ...

Agentic AI That Survives the Enterprise, Part 2: You Are Overbuying Intelligence

Part 1 argued that most enterprise agent failures are architecture failures. This part covers their favorite architecture mistake: paying frontier prices for work a cheaper model does just as well. Teams default to the biggest model because it feels safe. Then they run it billions of times on tasks like extracting a date from an email, and wonder why the AI line item looks like payroll. ...

Agentic AI That Survives the Enterprise, Part 1: Probabilistic Engines, Deterministic Businesses

Enterprises run on workflows that must be auditable, explainable, predictable, and correct. A single arithmetic error is not a quirk. It's a financial loss. Access control, data privacy, and robustness aren't features either. They're the price of admission. LLMs are the opposite kind of machine: probabilistic, open-ended, general-purpose brains. Brilliant at ambiguity, terrible at guarantees. Pu...

OpenAI Cuts GPT-5.6 Luna and Terra Costs, Reshaping API Budget Planning

OpenAI has reduced usage costs for two GPT-5.6 model variants, cutting GPT-5.6 Luna pricing by about 80% and GPT-5.6 Terra pricing by about 20%. The changes apply to API usage and to the way credits are consumed in ChatGPT Work and Codex. At the same time, OpenAI introduced a Fast mode for GPT-5.6 Sol that can process work up to 2.5 times faster at roughly twice the price, while Sol's standard pri...

You scroll products like Instagram reels, and the feed learns your taste — with no backend, no login, and no tracking servers. The whole recommender is ~150 lines of client-side JavaScript.

Cura doesn't have connector generation. I built a plugin, and a one-click installer, that does.

OrcaSlicer and PrusaSlicer both let you generate mechanical connectors, plugs, dowels, snaps, dovetails, when you split a model for multi-part printing. Cura doesn't, and it doesn't expose an official plugin API you can hook into to add this the right way either. That gap is why cura-connect exists. How I built it Two phases, verified at each step rather than assumed to work: Phase 1...

Sharing memory between processes with java.lang.foreign and jextract

Java Foreign Function and Memory API (java.lang.foreign) is a powerful tool that you can use to take advantage of various OS-specific optimizations. Often though, due to high usage of the C/C++ preprocessor and its powerful macros it can be cumbersome to write and maintain the Java-side code. Help is available in the form of jextract - a JDK tool that reads C/C++ header files (*.h) and gen...
