[Solved] Python question: How to convert list to sort with multiple keys? in c/programming@programming.dev
[โ€“] Fred@programming.dev 9 points 1 week ago* (last edited 1 week ago) (2 children)

Inside the lambda expression you can have a comprehension to unpack the keys list to get the same sort of uplet as your "manual" example, like this:

>>> items = [{"core_name": "a", "label": "b"},{"core_name": "c", "label": "d"}, ]
>>> keys = ["core_name", "label"]

>>> tuple(items[0][k] for k in keys)
('a', 'b')

>>> sorted(items, key=lambda d: tuple(d[k] for k in keys))
[{'core_name': 'a', 'label': 'b'}, {'core_name': 'c', 'label': 'd'}]
Simple table topper for gaming in c/diy@beehaw.org

Would some battons (like that: https://www.wickes.co.uk/Wickes-Redwood-PSE-Timber---44-x-44-x-2400mm/p/9000281515, or possible smaller depending of the profile of your table), fixed to the underside of the gaming top so that they're leaving a negative image of the fixed table top? That way, once installed, the gaming top can't slide around. That would only work well in my mind if the gaming top is a single piece.

Edit: with that idea, minimal length of the gaming is that of the table plus two thicknesses of the baton you'd use, ie. more than the 20mm you seem to have in mind. Maybe, maybe not an issue.

For the cover, I'd consider a felt with a waterproof backing, although I don't have a specific material in mind. If you don't add felt, I'd soften the angles of the MDF.

A crate for puppy (europe.pub)
 

I made a crate for puppy! He keeps outgrowing the ones we bought, so I made a large one out of his playpen panels that should be big enough until he's fully grown.

The floor is a sheet of plywood. I put vinyl wrap on it for waterproofing (turns out it's too fragile, by the time I made the rest I made a couple of tears).

For the top, I made a lip out of PSE wood (I think 25mm), to give more rigidity and allow fitting a hinged top.

Cabin hooks for the door, but they turned out to be too loose, so I added a Brenton bolt.

Puppy likes it, so overall a success!

Oiled with tung oil,still oily 9 days later (europe.pub)
 

Hi,

Weekend before last (ie Sunday 24th) I applied tung oil to plywood (simply described as "12mm hardwood plywood" by the DIY shop). One week and a bit later, it looks dry to the eye, there is no shiny spot, the wood has a warmer colour, but if I run my fingers on the surface I get a tiny amount of oil.

I applied the oil by pouring a small amount on the surface of the wood then rubbing with an old rag, leaving no pool of oil.

Sunday (the day before yesterday ) I used kitchen towels to try to dry it off. The towels picked up a tiny bit of oil, but evidently not everything.

Is tung oil that slow to dry? Should I wait another week? Can I do something to help the process along? (Sanding or steel wool? Too aggressive for the thin veneer of plywood? Rub with a small amount of white spirit? )

I'm making a crate for Puppy who has outgrown two crates already, I picked the oil that was advertised as food & toy safe without realising how difficult it'd be to apply. In fact that's my most ambitious project to date, I'm really a beginner.
