It might be “weird” that this link was submitted to HN, but the purpose of No Tech Magazine is to host things that Low Tech Magazine links to, to ensure the articles don’t suffer link rot.
There is a little value to the current link. I didn't know about No Tech Magazine, but now I do. It lead me to read several other interesting articles, which would not have been the case if I'd landed on the fridge article's original source.
Submitters, can you please link to the original source if the one you link to adds no value?
