Tracing a multi-agent LLM system: otel-swarm and a SigNoz dashboard pack

The problem A single LLM call is easy to reason about. You send a prompt, you get tokens back, you log the latency and you move on. A swarm is not that. Four or five agents run, some in parallel, each with its own model. One of them times out and quietly falls back to a cheaper model. A critic agent reads the output and sends work back for another round. When the whole thing takes 40 s...

Andrej Karpathy's "Deep Dive into LLMs like ChatGPT"

As a software engineer, I use Claude Code to write code, generate architecture diagrams, investigate issues, complete Jira tickets, u...

Best Data Grid for Python Dash in 2026

Dash gives us a way to put Python data in a browser. There is a lot of stuff we can add there, but main focus of this article is data grids, its the most common request for us. I work on RevoGrid, so I know that option best. But RevoGrid is not the only choice, and different grids suit different projects. Here is the short, practical version of how the main Dash data grids compare in 2026. ...

The checklist I wish I'd had before my first mainnet deploy

Pilots run a checklist before every takeoff. Surgeons run one before every incision. Not because they forgot how to fly or operate — because the cost of skipping a single step under pressure is too high to trust to memory. Shipping a Solana program to mainnet-beta belongs in that same category: irreversible actions, real value on the line, and a dozen small things that each seem obvious right up u...

I tried to port an Indian FII/DII trading strategy to MNQ, MES, SPY, and QQQ — it lost money on all four

A trading YouTube podcast (Upsurge Club, ft. Amit Dhamija) describes a strategy built entirely around India's NSE exchange data: daily FII (Foreign Institutional Investor) / DII (Domestic Institutional Investor) / Proprietary / Retail participant-wise open interest. The claim is that tracking whether "smart money" is building or unwinding positions gives a real edge over price action alone. I wan...

Web effects with an X-ray mode: toggle a layer, see which lines of code it owns

Copy-paste an effect from anywhere and you get a finished snippet. It works, or half-works, and the moment you want to change one thing you're reading forty lines trying to find which one does it. TinkerFX is 79 web effects built the other way round: every one of them comes apart. Toggle a layer off, and its code gets struck through Each effect is split into named layers. Turn one off...

I Built a Free Image Editor Because I Didn't Want to Pay for an Expensive One

Building an Open-Source Image Editor Because the Alternatives Were Too Expensive When I started integrating image editing into one of my applications, I evaluated several popular image editing libraries. Many of them were excellent. They offered polished UIs, powerful editing capabilities, and years of development behind them. However, I quickly ran into a problem. No single library ...

Four ways a file-sync tool eats your data, and how to not

I've been building a small sync tool — it moves files between a remote project and a local folder, git-style (clone, pull, push, status). The moment you write a tool that touches other people's files on both sides of a network, you inherit a category of bug that's worse than a crash: silently destroying work the user can't get back. Here are four data-loss traps I hit (or nearly hit), each with t...

Stop Validating AI Agents Only at the Start: Introducing Mid-Chain Governance

Modern AI agents rarely complete a task in a single model invocation. Instead, they execute multi-step workflows: Retrieve documents Call APIs Query databases Generate intermediate plans Invoke external tools Produce a final response Most AI safety mechanisms, however, only validate the initial prompt or final output. This leaves an important gap. The Hidden Risk in Multi-Step AI Workflows Im...

LangChain’s tool routing is a bloated mess. So we built a <10ms local semantic registry to replace it at US Neural.

Look, LangChain was great to get the ecosystem started 0 to 1. But let's be honest: taking LangChain to production with 50+ tools is a nightmare of abstraction hell and brittle if/else logic. The AgentExecutor is slow, and relying on it to route complex tools feels like fighting the framework. Tool discovery shouldn't be an LLM's job, and it shouldn't require a heavy python wrapper. It’s a distri...
