SSR + Suspense - React Router v7

I was trying to implement SSR with rrv7, i didn't want to use smelly useQuery's isLoading and isError states( i might be dumb for that, pls point it out if i am wrong ) , so i went for useSuspenseQuery and used a Suspense Boundary with LoadingSkeleton to make it look beautiful It was very late when i realised that only skeleton was loading when JS was disabled, implying that SSR was only rendering...

What the browser can actually tell you about your hardware (and what it can't)

I spent a while building browser-based hardware diagnostics and came away with a much clearer sense of where the web platform is genuinely capable and where it quietly lies to you. Notes below, with live demos for each API so you can poke at them yourself. Refresh rate: requestAnimationFrame is the only signal you get There's no screen.refreshRate. The only approach is timing requestAn...

Four patterns that keep my YouTube longform JSON queue from going stale

I manage the YouTube longform queue for my BuilderStack channel as JSON files in content/yt-longform-queue/. A spec file lands there when a generator script commits a new dialogue; the publish workflow picks the file, renders it to MP4, uploads it, then moves the file to uploaded/. No external queue service, no database rows, no management dashboard. This has worked for three months without a maj...

Code Review From the Terminal and CI, No MCP Client Required

A month ago I shipped aicraft-code-review, an MCP server that reviews code locally. This week I added a CLI mode — because not everyone wants to wire up an MCP client just to check a diff. Now the same reviewer runs three ways: MCP tools — review_code / review_diff / review_file inside Claude Code, Cursor, Cline CLI — mcp-code-review review-file path/to/file.py CI — pipe git diff into it an...

How to Catch a Pine Script Repaint Bug Before It Costs You Real Money

I've watched too many TradingView strategies look great in the Strategy Tester and then fall apart the moment real money went live. Almost every time, the code compiled fine. The bug wasn't syntax. It was repainting, the script quietly using information it shouldn't have had yet. Repainting doesn't throw an error. It just quietly makes your backtest better than your live trading will ever be. Her...

Why your App Tracking Transparency prompt doesn't show up (and how it got my app rejected)

App Review rejected my iOS app under Guideline 2.1. The note said reviewers were unable to locate the App Tracking Transparency permission request when they tested the build. The prompt worked on my iPhone. Every single launch. It just didn't work on theirs. The cause turned out to be two properties of the ATT API that are easy to miss individually and genuinely nasty in combination: together th...

So…#WTH is State Machine Replication?

Every replicated database, Kafka partition, and Raft cluster relies on one rule: if deterministic replicas start identical and apply identical commands in an identical order, they stay identical. Violate the order by one message, and you’ve built two different databases. In my blog, I learnt and then broke down the mechanics of State Machine Replication (SMR). I cover: -> The Deterministic Pr...

Building Multi-Agent Systems That Actually Scale: Lessons from Hermes, LobeHub, and the 2025 AI Agent Explosion

Originally published on tamiz.pro. The AI agent landscape shifted dramatically in 2025. What began as single-agent chat interfaces exploded into multi-agent ecosystems where dozens or hundreds of specialized agents coordinate, debate, and execute complex workflows. Hermes and LobeHub emerged as two distinctive approaches to this problem—neither a toy demo nor an enterprise suite—and their archite...

"I turned an IEEE amusia research prototype into a real-time pitch correction app — open source, runs entirely on-device"

*About 1.5% of people have congenital amusia *— their brain genuinely can't tell pitches apart, no matter how much they practice. Most "can't sing" cases are just undertrained ears; this isn't that. There was an IEEE research prototype built to give people real-time pitch feedback, but it lived as a Streamlit demo — stuck on a laptop, unusable by anyone it was actually meant for. I rebuilt it as...
