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!

The host of the crate:

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.

Hi,

I have to interface with systems that use iso-8859-x encoding (not by choice...), and I'm surprised that the following doesn't throw an error:

>>> str(bytes(range(256)), encoding="iso-8859-1", errors="strict")
'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~\x7f\x80\x81\x82\x83\x84\x85\x86\x87\x88\x89\x8a\x8b\x8c\x8d\x8e\x8f\x90\x91\x92\x93\x94\x95\x96\x97\x98\x99\x9a\x9b\x9c\x9d\x9e\x9f\xa0¡¢£¤¥¦§¨©ª«¬\xad®¯°±²³´µ¶·¸¹º»¼½¾¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ'

Bytes in the 0x80—0x9f range are not valid iso-8859-1, and I was expecting the above to raise a DecodeError of some sort; instead it looks like those are passed through.

I'm perfectly happy with this behaviour, I would like to make sure I can depend on it. Can I take an arbitrary byte buffer, decode as ISO-8859-1, and never get any error? Is it guaranteed to be lossless ?
