You know what would be really cool?

Published by Silveira on 2026-06-15

Sometimes while driving on a long trip I end up caught in a thought exercise. A creativity game that we can call “You know what would be really cool?”.

Then I try to think of something original. A movie, a game, a book. It’s also a world-building exercise. Then after some mashing of different genres and elements, I always come up with the same idea: “a space opera that’s also a western and that’s also a samurai movie”.

Sometimes I spend a bit iterating on this idea until I’m interrupted by some background thought that screams “Star Wars did it first!”.

The asymmetry of the historical record

Published by Silveira on 2026-05-21

“Yeah, I think that, I think it is important to recognize that much like the present, the past is largely a chronicle of misery.

I mean, people suffer. And the people who suffer the most leave the least evidence behind. And so, any history that begins with what survives has a real challenge to arriving at any proper perspective on the human condition.

I think that is the asymmetry of the historical record, right? The people who were wealthiest and most literate and had the greatest resources, not only left, not only made a lot of records, they managed to have their records preserved. And everyone else disappears and just vanishes, their remains are gone.

And I think it puts a special obligation on anyone who’s trying to write history or tell a story about the past to be attentive, to not give up in the face of the asymmetry and to try to repair the historical record by finding other kinds of evidence, the evidence that does survive, that makes sure that we understand the lives, both of the powerful and the powerless.”

Treat the elderly as you would your own elders, and the young as you would your own children

Published by Silveira on 2026-03-12

老吾老以及人之老，幼吾幼以及人之幼

“lǎo wú lǎo, yǐ jí rén zhī lǎo; yòu wú yòu, yǐ jí rén zhī yòu”

“Treat the elderly as you would your own elders, and the young as you would your own children.” Mencius (孟子)

Found this quote in this interview of Michael Crook by Dan Vineberg.

There is something similar in the Bible, Paul’s letter to Timothy (1 Timothy 5:1):

“Do not rebuke an older man but encourage him as you would a father, younger men as brothers,”

misery loves company

Published by Silveira on 2026-01-01

Doctor Faustus asks Mephistophilis why Satan seeks to enlarge his kingdom. Mephistophilis replies with the Latin phrase: 

“Solamen miseris socios habuisse doloris“

This roughly translates to “It is a comfort to the unfortunate to have had companions in woe,” or simply “misery loves company”.

Doctor Faustus, by Christopher Marlowe, written in the late 16th century and first performed around 1594.

3 keys and knob keyboard

Published by Silveira on 2025-12-26

A very useful and also inexpensive mini keyboard found on AliExpress. Mine is the specifically this one. I have added the notes myself using a Brother P-touch label maker.

Here is the drivers and configuration application in a Google Drive. Note to myself: if this share is deleted, search for “3 key keyboard software-20251226T192116Z-3-001.zip” in your own Google Drive.

This is how the “MINI KeyBoard.exe” looks like:

It should display “Connected”. To modify each key, click the green keys (left top corner), it will become red. Then select the operations then click “Download”.

This is my configuration as of today:

  • KEY1: Win L (Go to “KEY”, then select the keys. This locks the computer).
  • KEY2: Win Ctrl V (Go to “KEY”, then select the keys. This is the Windows sound output selector.)
  • KEY3: Mute (Click “Multimedia” then mute)
  • K1 Left (Knob scroll left): Volume- (Click “Multimedia” then “Volume-“)
  • K1 Right (Knob scroll right): Volume + (Click “Multimedia” then “Volume+”)
