A short circuit occurs when there is a new path of least resistance created in the circuit. For example, the worn out wire of your lamp touching a different neutral wire.
When there is a new path of least resistance, MUCH more current is delivered through this path (Ohm's Law, I = V / R). When current increases, that power is dissipated as heat (Joule's Law, P = I^2 * R). That heat can melt insulation and start fires.

The FIRST $1.50 hot dog combo may have been sold in San Diego on Morena Blvd at the original Price Club store (the Costco I regularly go to!! Costco Warehouse #401).
Not only that, this location was the FIRST ever Price Club, founded by Sol Price in 1976. Price Club merged with Costco in 1993 to form "PriceCostco", later renamed "Costco Wholesale Corporation".

For sourdough, be precise with measurements (hydration, ingredients) but flexible with time. Rely on the dough's temperature and visual feedback (yeast activity) to determine bulk fermentation and final proof readiness.

To minimize waste, refrigerating sourdough starter is more forgiving than reducing its size while maintaining daily feeds. Smaller starters are less stable (due to reduced microbial mass), more temperature-sensitive, and show less visible activity.

Breadmaking has evolved through several key milestones::
- Early breads were simple flatbreads (e.g. naan, pita, tortilla) made from flour and water.
- Leavened bread began with sourdough, naturally fermented by wild yeasts and lactic acid bacteria.
- In the 19th century, scientists isolated a specific type of yeast and began mass-producing it, making commercial yeast a fast, reliable leavening agent for both bakers and home cooks.

Google Chrome's DevTools has a "Local overrides" feature that lets you modify network responses? Incredibly useful for testing frontend behavior by tweaking backend responses, or even mocking backend APIs before they exist.

Each Jupyter notebook typically connects to its own kernel, which executes code and maintains state (variables, imports). Though isolated by default, notebooks can share state by connecting to the same kernel. Kernel handling varies by environment - Jupyter Server allows multiple users to connect to same server/kernels, while VS Code manages kernels locally with one per notebook by default.

In Go, passing a slice by value still permits in-place modification of its elements. That's because the slice contains a pointer to the underlying array, along with its length and capacity. https://go.dev/src/runtime/slice.go
