CPython still needs to update reference counts after the fork even if your python code itself doesn't modify any data, making Copy on Write less helpful than it would first appear. Monolithic memory buffers like numpy arrays can be shared efficiently via CoW, but rich data structures with many PyObjects suffer from the refcounting issue.

To make this more clear as I have had the same experience and want more people to enjoy it: Mamba is more or less a drop-in replacement for the conda tool with the guts rewritten in C++ and as a result is much faster to resolve dependencies -- I want to say an order of magnitude faster or more. It's even noticeably faster at downloading and installing. You just

  conda install -c conda-forge mamba

in your base environment and then you can start running mamba instead of conda.

TIFF will support that size and larger. It can use JPEG or ZLIB compression as standard, or even WEBP or JPEG-XL which are unofficially supported by a small number of TIFF libraries.

I’ve used those Snappy brand cutters in a handheld cordless drill. It’s workable but tricky. You need to start with light pressure and high speed until the cutters score a clean circle, then gradually increase the pressure. The workpiece absolutely needs to be clamped down with zero movement, and it helps if you can find a way to brace your upper body and the drill as you work. The trickiest part is keeping the cutter perfectly square to the work in both axes —- if you tip it too far you’re likely to shatter the cutter as the metal is very brittle.

Also if the upper tray is height-adjustable, check the rubber one-way valve flaps in the middle of the supply tube that runs up the inside rear wall of the basin. If any of those flaps are damaged or missing, water will leak out there instead of being directed to the spray arm depending on which height position you're using. If you're lucky, you might still have one usable height position without replacing anything. Otherwise you need a whole new supply tube ($60-100) as the rubber part doesn't seem to be sold separately.

Nice work avoiding the copula there :)

PDF had support for JS at least since the late ‘90s as part of the scriptable forms system.
