  * 2023-04: on-browser streaming + light browsing on <Ubuntu 22.10>: about 2h45. Too low! Gotta try buying a new battery.
* 2022-01-04 updated firmward after noticing that <ubuntu 21.10 does not wake up from suspend> seemed to happen every time when not connected to external power. `dmidecode` diff excerpt:

  used the "Ubuntu Software" GUI as mentioned at: https://support.lenovo.com/gb/en/solutions/ht510810-how-to-do-software-updates-linux[]. Kudos for making this accessible to newbs.

  After doing that, another update became available to: 0.1.56, clicked it and was much faster than the previous one, and didn't auto reboot. After manual reboot, `dmidecode` diffed again:

  plus a bunch of other lines.
* 2021-06-05 upgraded to <Ubuntu> 21.04 with a clean install from an ISO. Selected
  * "Minimal installation"
  * "Erase disk and install Ubuntu". Notably, this erased the <Microsoft Windows> that came with the computer and was never used not even once
  * "Erase disk ans use ZFS"
  * Encrypt the new Ubuntu installation for security
  After this, the GUI felt fast, who would have thought that erasing a bunch of stuff would make the system faster!

  which gives an idea of how the above map to mountpoints.

  Had two GUI freezes since installation, a fixed images shows no matter what I do, possibly graphics only, but impossible to tell (next time I'll try SSH access). No <Nvidia> drivers installed yet.

2020-06-06: dropped some lemon juice on the bottom left of touchpad. Bottom left button not working anymore... I'm an idiot. There are many other alternatives, but very aggravating, I'll replace it for sure. Can't find the exact replacement part or any videos showing its replacement online easliy, dang. For the T430: https://www.youtube.com/watch?v=F3lzV9uXRjU Asked at: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile-Workstations/P51-left-bottom-button-below-trackpad-mouse-left-click-stopped-working-possible-to-replace/m-p/5019903 Also I could not access it because you need to remove the HDD first: https://www.youtube.com/watch?v=5Klawxc7T_Y and I can't pull it out even with considerable force, unlike in the video... And OMG, those button caps are impossible to re-install once removed!!! Then when I put the whole thing back together, the upper buttons were not working anymore. FUUUUUUUUCK. When first opening I pulled on it without properly removing the cap and it came off, but it didn't look broken in any way and I put it back in. Keyboard works thank God, so right black connector is fine, left white one oppears to be the one for upper keys and trackpoint, both of which stopped working. The hardware manual confirms that they are both part of the same device, so basically a mouse :-) TODO can it be bought separately from te keyboard? Doesn't look like it, photo of keyboard part includes those buttons. The manual also confirms that the bottom buttons are one device with the trackpad "trackpad with buttons", thus forming the second entire mouse.

2019-04-17: popup asking about "ThinkPad P51 Management Engine Update" from from 182.29.3287 to 184.60.3561, said yes.

<Ubuntu> 17.10 setup after buying it:

* partition setup: https://askubuntu.com/questions/343268/how-to-use-manual-partitioning-during-installation/976430\#976430
* BIOS:
  * for NVIDIA driver:
  * for KVM, required by Android Emulator: enable virtualization extensions
* TODO fix the brightness keys:
  * failed: https://askubuntu.com/questions/769006/brightness-key-not-working-ubuntu-16-04-lts/770100\#770100

Battery life shown by Ubuntu battery app after installation:

* before NVIDIA driver setup: 8h
* after: 6.5h

Unknown real developer name, claims to be from <Canada> on YouTube channel about: https://www.youtube.com/@TheBibitesDigitalLife/about[], likely because he's a software developer and wants to keep his employer's claws away from his side project.

Appears to be <closed source> unfortunately, so not suitable for research.

<video What will happen after 100h of evolution? by The Bibites (2022)> mentions it was started five years ago, so circa 2017.

Appears to be <Unity>-based, if you download and extract for <Linux> you get files named `UnityPlayer.so`.

Author is named Leo Caussan in game credits at startup: https://www.linkedin.com/in/l%C3%A9o-caussan-560350136/[], a <Canadian> <software engineer>.

Was not very <Linux> compatible: https://www.reddit.com/r/TheBibites/comments/vqk6ac/program_stalls_at_a_blue_screen/ Trying to run 0.5.0 leads to a blank screen after you click "start simulation".

<Ciro Santilli> has felt that perhaps what is missing in 2020's <AGI> research is:
* the interface between:
  * the continuous/noisy level (now well developed under <artificial neural network> techniques of the 2010's)
  * and <symbolic AI> level AI
  The key question is somewhat how to extract symbols out of the space-time continuous experiences.
* more specialized accelerators that somehow interface with more generic <artificial neural networks>. Notably some kind of speialized processing of spacial elements is obviously hardcoded into the brain, see e.g. <grid cell>{full}

Forcing these boundaries to be tested was one of the main design goals of <Ciro's 2D reinforcement learning games>.

In those games, for example:
* when you press a button here, a door opens somewhere far away
* when you touch certain types of objects, a chemical reaction may happen, but not other types of objects
Therefore, those continuous objects would also have "magic" effects that could not be explained by "simple" "what is touching what" ideas.
