Manufacturers know people do this. The TV will attempt to connect to any open network (neighbors) and I'd be shocked if they haven't at least considered packaging them with 4G/5G antennas. You're gonna need a Faraday Cage.
If you try to render tables with millions of cells the browser does a really poor job and the performance is abysmal. The only solution when you need to render that many cells is to virtualize the table and only have the visible cells (plus some buffer) actually in the DOM at a time. That plus weird restrictions browsers put on certain table elements (looking at you thead) that prevent them from being "sticky" headers means that the developer is left with absolutely positioned divs as the only solution. Blame browser vendors for not providing a native way to present tabular data with more than a few hundred thousand rows without causing performance issues.
The term "range" (in the context of a "home") typically describes a multi-function cooking appliance that features a rangetop for heating pots and an oven directly beneath it. Why is this page about lightbulbs? The subtitle even has the word they should've used instead of "range": "products".
The react-virtualized library works around this issue by scaling the the scroll position it sets for a row based on the ratio of "max CSS height allowed by browser" to "computed height of all rows" if the latter is greater than the former: https://github.com/bvaughn/react-virtualized/blob/master/sou...
It's quite astonishing how complicated it is to draw lines in 3D graphics. As a novice it was a little unbelievable that the primitives for drawing lines was effectively limited to a solid screen-space pixel wide line. Want to draw a 2 pixel wide line? Do it yourself with triangles.
