(By the way, I don't mean to imply Scott Aaronson finds complex numbers weird. He's just wondering why not other systems, and even mentions quaternions as an alternative — which could be called weird in their own right... So in a sense I'm attacking a straw man.)

Great video, except for a few wrong details that really get to me...

- The pixels in an LCD aren't little light bulbs. They are little lamp shades. (The pixels in an OLED display are little light bulbs though)

- A CRT doesn't shoot light. It shoots electrons.

- The video makes it seem like pixels in an LCD update all at once. Not true! They're scanned.

- The video makes it seems that there's no temporal bleeding on CRTs. This sounds unlikely to me...

- The main difference in image quality between coaxial and composite inputs is not that coaxial needs to stuff audio and video together. It's that in coaxial the signal is shifted to a carrier frequency as if it came from an antenna (usually channel 3 or 4) so the decoder needs to bring it down to the frequency it uses internally (called the intermediate frequency) before sending it to the screen. This degrades the signal.

Argh I was making some changes and messed things up. Sorry about that.

This is a library for use in Streamlit (which is a Python framework for data apps), and Streamlit already supports Vega-Lite behind the scene. So I'm just riding on their Vega-Lite.

Here's more info about Streamlit: https://streamlit.io

(BTW I'm a cofounder there :) )

Check out the example app, linked in the README. I meant for that to be a replacement for the README, since it actually lets you interact with the plots.

But I'll add a picture to GitHub anyway

I just have alternate layouts depending on what I'm doing.

English, programming, and some bits of Portuguese = US keyboard + compose key

Portuguese = US-intl (but in mine, all the keys you mentioned are dead keys. No Alt need)

Hey, Streamlit co-founder here.

This should just work out of the box in Streamlit:

caption = st.text_input("Meme subject or caption")

if caption: # do search here

If that doesn't work for you, do you mind posting in our forums? I'd love to get to the bottom of this!

(Cool app, btw!)

Chrome on Linux here. Google Meet blurs my background just fine.

Or perhaps the opposite could happen: as more and more people start carrying devices that have access to the internet via cellular connection, airports could start providing Wi-Fi for free, as they could use that for tracking, marketing, and other "fun" uses

Actually, Observable is not JavaScript:

I think it's an amazing piece of technology, hosting some of the best interactive stories on the internet — but I too find it hard to use.
