Sales Call CRM Actions: Node.js MP3/WAV Speech-to-Text Uploads Across US/EU

The constraint that changes this choice is provider portability. A sales-call transcript is an intermediate artifact, not the product: the useful output is a small set of CRM actions that can survive a transcription provider change. For a Node.js application accepting MP3 and WAV uploads in the US and EU, the fastest integration is the one with a narrow adapter, an explicit regional policy, and an...

Running an AI image upscaler & sharpener 100% in the browser (TensorFlow.js)

I wanted to sharpen and upscale images without uploading them to some server. It turns out you can run the whole ML model right in the browser — the image never leaves the device. Here's what I learned shipping it as two free tools. The stack TensorFlow.js (WebGL backend) for inference UpscalerJS as a thin wrapper around an ESRGAN super-resolution model All loaded from a CDN — no bu...

Data Scientist Learning JS: Promises and resolve()

Context: I'm a data scientist/analyst (in Python and R) learning development from scratch. Inevitably, I am learning these through the lens of what I already know. If you have a similar background and are a beginner developer, I hope these analogies help! Any comments, especially if you spot any misunderstanding, are appreciated. Commenting is caring <3 Motivation: I was building a mock data l...

Parallel Coding Agents Need Handoffs, Not More Terminals

The concrete problem Running two or three coding-agent sessions is easy. Knowing when their work is safe to combine is not. One session changes an API while another writes regression tests against the old shape. A third investigates a production failure and quietly edits the same configuration file. Git worktrees prevent immediate filesystem collisions, but they do not explain task dep...

I Score Every Trending Topic Before Writing About It. I've Never Scored My Own 30 Articles.

Twice a day, a scheduled task in this repo pulls DEV.to's top posts for six tags (ai, llm, mcp, claudecode, agents, productivity), scores each one as positive_reactions_count + 3*comments_count, and picks the highest scorers that don't already overlap with something I've written before. The task prompt is explicit about the second half — cross-reference against my own back catalog, reject anything...

My MCP Server's GitHub Token Can Write. The Code That Promises It Never Will Had No Test.

My MCP server (developer-presence, the one that lets Claude check my GitHub profile and manage my DEV.to posts) has exactly three GitHub tools: get_github_profile, list_repos, get_repo_stats. All three read data. None of them create, update, or delete anything. The GITHUB_TOKEN behind them isn't scoped that way. My own key_facts.md says it plainly: Token scopes needed: `repo`, `user` — add `de...

Building a Production AI Agent in Spring Boot: Canary Releases, Model Fallback, and Cost Caps (Part 10)

Last Monday I shipped the shipping-tool prompt from Part 9 to 5% of live traffic. It had won the pairwise gate 24 to 7 with 9 ties, the tool discipline diff was clean, and the money-path cases read fine by hand. I went for lunch confident. At 6:42pm the canary dashboard disagreed. P95 latency was up 38%. Tool calls per conversation had climbed from 3.1 to 5.4. The reworded tool description I was ...

Alexa, Are You Testifying Against Me?

Your smart home is not smart. It is just very, very observant. I did not buy a smart speaker because I wanted a friend. I bought it because it was on sale for $29.99 and it promised to play rain sounds on command. For two years she lived on my kitchen counter. She set timers for pasta. She told me the weather with the aggressive optimism of someone who has never paid rent. She was h...
