Silicon Keyboard cover

I have a silicon keyboard cover, it is full of dust and it won't stick, If I wash it soap and water will it remove the dust and stick again? I remove the cover every time I finish using the laptop, because I heard it can damage the screen, and effect the closing of the lid. --つがる Talk to つがる:) 🍁 02:10, 4 December 2020 (UTC)[reply]

Have you tried rinsing it with just lukewarm water and just a drop of soft soap or a mild liquid detergent? This is a howto on cleaning silicone keyboard covers; since it is hosted on the website of the Houston Chronicle, a reputable newspaper, where it was published eight years ago, I think we may assume it is sound advice. With certain laptop models, such as MacBooks, leaving the cover on when closing the lid can indeed damage the screen. --Lambiam 08:54, 4 December 2020 (UTC)[reply]

Math notation on Everipedia

The site called Everipedia has copied every Wikipedia article and their project appears to be running a Wikipedia-like site on a blockchain.

However, everything that is in mathematical notation on Wikipedia appears there simply as a non-editable image, rather than using anything like Wikipedia's TeX-like software. Their spokesperson explains this by saying things that are possible on Wikipedia may not be possible on a blockchain. I don't trust his word on this because he omits too much.

Does his claim have any merit?

(Whether it does or not, Everipedia ought to announce that the mathematical sciences are unwelcome there.) Michael Hardy (talk) 20:40, 4 December 2020 (UTC)[reply]

It sounds like malarkey to me. --Lambiam 21:27, 4 December 2020 (UTC)[reply]

There's no reason the notation can't be stored as plain text on the blockchain and then rendered as the formula in the browser when a user wants to view a page --Condimentary (talk) 22:25, 9 December 2020 (UTC)[reply]
