Why is my hot water cylinder making this noise? And please can it stop? Anyone know what’s going on?

PSA for Australia (especially QLD, NT, SA, WA): You can watch the ABC’s NSW feed in iview, and go to bed up to two hours early tonight. #australia #newyear

Vaguely fun thing I discovered - https://www.youtube.com/results?search_query=Podnews&sp=EgIIBxgA This search query to YouTube is a scoped search to *just* search for podcasts. The "sp=EgIIBxgA" bit is the filter you want. If a creator hasn't marked their content as a podcast, it won't appear in this search. I've, boringly, sent a feature request for that filter to be surfaced somewhere in the YouTube interface. Because that would be nice, wouldn't it?

Started reading my email but just can't be bothered today
