Term of the day01
Transfer Learning
“Using a pre-trained model”
Taking a model trained on one task and adapting it to a different task. The early layers learn general features (edges, syntax patterns) that transfer. Only the later layers need task-specific training. This is why you can fine-tune BERT for any NLP task.

Prompt of the day03
Build a dashboard
Build a personal metrics dashboard in Next.js. Metrics: [list your five: name, source API, what good looks like]. Layout: a top row of stat tiles (current value, % change vs previous period, sparkline), a main line chart for [primary metric] with range toggles (7d/30d/90d), and a breakdown table for [dimension]. Fetch server-side with keys from env vars; cache responses 5 minutes; show a last-updated stamp and color the tiles green/amber/red against the targets I listed. Password-protect the page simply. Deployable to Vercel.
