I built Unicode Text Tools , a free site with a bunch of text converters — superscript, subscript, bubble/circled text, upside-down text, small caps, and more. Type something, get it transformed, copy it out. The whole engine is one dependency-free JS file built entirely from character mapping tables . No AI, no server, no libraries. Here's why that's the right architecture for this class of tool, and how the trickier conversions work. The core idea: it's all just lookup tables ...

More agents do not automatically produce better engineering. They usually add total tokens, duplicated context, handoff delay, and integration risk. Their defensible advantages are narrower: reduced elapsed time for independent work, isolated investigation, or specialist evidence that one agent might omit. The useful question is therefore not “Can this task use subagents?” It is: Does this task contain independent, bounded work whose value exceeds the coordination cost? Codex Ho...

LLMs can now call tools, but turning their output into a trustworthy event stream is still a puzzle. We wire Claude’s function‑calling to an SNS FIFO topic, giving you ordered, deduplicated notifications that downstream Lambda functions can consume with zero‑loss guarantees. Why SNS FIFO Is a Good Fit for LLM‑Generated Events When an LLM decides to “publishAlert”, you usually want the alert to be processed exactly in the order it was generated . Imagine a fire‑alarm system ...

There is a habit I have for other people's libraries that I do not have for my own code: before I call something, I read what it returns. With my own functions I skip that, because I wrote them, so I know. Three times in three days that turned out to be false, and the third time I caught it before it cost anything only because I had started treating my own modules like somebody else's. The version I had already been burned by twice I maintain qbofile , a set of browser-based ...

Customizing cell backgrounds in Excel is one of the fastest ways to transform a plain data dump into a professional, scannable report. Whether you need to highlight headers, flag key metrics, or add visual polish to dashboards, the Free Spire.XLS for .NET library makes it easy to apply solid fills , texture patterns , and gradient effects programmatically. In this guide, you'll learn how to implement each style with concise C# examples. Prerequisites Install the libra...

TL;DR An agentic RAG pipeline treats retrieval as a tool the AI agent can call, evaluate, and call again rather than as a fixed step. The pipeline can search an internal knowledge base first, then use real-time web search when the available evidence is missing, weak, or outdated. Internal documents and web results should be converted into a shared evidence format before the model generates an answer. A reliable system must preserve URLs, publication dates, document identifiers, and t...

I just started a blog and published my first blog post about Logical Volume Management. I'm new to documenting my work, so I'd really appreciate any feedback on the content, clarity, or writing style in general. This site is a mix of a blog and a portfolio. Since I'm new to all of this, it would be great to get some feedback on whether this post works well just as a blog post, or if it actually holds up as a portfolio project too, before I keep writing more. www.mvtechblog.com Thanks ...

The schema catalog for an AI assistant is the artefact that answers the question "what does this database look like right now". Whether the database is Postgres, MySQL, SQL Server or Redshift, the shape of the problem is the same: the catalog carries table names, column names, types, keys, and enough relationships to let the assistant write a query that resolves. It lives somewhere between the database and the assistant, has to stay in sync with a database that changes underneath it, and is almo...

The strongest candidate I ever voted no on solved the problem in eleven minutes. Clean. Optimal. Caught the edge case I normally have to hint at twice. Then I opened my notes to write the scorecard and found one line: "Solved it. I have no idea how." That is the short version of why strong engineers fail coding interviews. Not because they can't code. Because nothing they did survived the trip from the room to the scorecard. The interview is not the thing being graded. The document I wri...

As of August 26, 2026, GitHub reports that 398 merged pull requests carry my name on the author line. Twenty nine of those live inside repositories that I own myself, so I removed them from this count on purpose. What remains is the number that actually matters to me: 369 pull requests merged into other people's repositories , across 33 external projects , maintained by strangers who had zero reason to trust my code. Every single one of those 369 merges is real, dated, and linked in th...
