Another thing that makes home construction a bit different in this regard is that you could claim to build a house for yourself, live in it for a bit, and then sell it on a couple of years later. That'd be an easy way to avoid or evade taxes. Not so easy with lettuce -- once you've eaten it, you've eaten it.

On my workstation, I run statistical simulations in R which can be wasteful with memory and cause a lot of transient memory pressure, and for that scenario I do like that zswap works alongside regular swap. Especially when combined with the advice from https://makedebianfunagainandlearnhowtodoothercoolstufftoo.c... to wake up kswapd early, it really does seem to make a difference.

That said, if you want it to behave at its best when OOM, it does help to tweak vm.swappiness, vm.watermark_scale_factor, vm.min_free_kbytes, vm.page-cluster and a couple of other parameters.

See e.g.

I don't know of any good statistics script for zswap, I use the script below as a custom waybar module:

  #!/bin/bash
  stored_pages="$(cat /sys/kernel/debug/zswap/stored_pages)"
  pool_total_size="$(cat /sys/kernel/debug/zswap/pool_total_size)"
  compressed_size_mib="$((pool_total_size / 1024 / 1024))"
  compressed_size_gib="$((pool_total_size / 1024 / 1024 / 1024))"
  compressed_size_mib_remainder="$((compressed_size_mib * 10 / 1024 - compressed_size_gib * 10))"
  uncompressed_size="$((stored_pages * 4096))"
  uncompressed_size_mib="$((uncompressed_size / 1024 / 1024))"
  uncompressed_size_gib="$((uncompressed_size / 1024 / 1024 / 1024))"
  uncompressed_size_mib_remainder="$((uncompressed_size_mib * 10 / 1024 - uncompressed_size_gib * 10))"
  ratio="$((100 * uncompressed_size / (pool_total_size + 1)))"
  echo "$compressed_size_gib.$compressed_size_mib_remainder"

Of course, the parent may also have been referring to getting clients to pay in cash and not putting anything on the books, at the expense of getting barely any pension in the end, but that's not how I read it. This is getting somewhat less common because people are more likely than 20 years ago to get a loan from a bank to pay for renovation work, and the bank will want to see invoices.

The installer also completely broke the Windows partition that came with the workstation even though I was planning on dual booting, but oh well, no great loss there.

Other than that, there are some small conveniences and apps that I miss from MacOS (the mac calendar and mail apps are just so nice!) but the Niri window manager is just so amazing that at this point I don't think there's anything that could make me switch back.
