If "i" wasn't called "imaginary" I don't know if anyone would find it weird when it appeared in physics.
In many ways i is as weird as negative numbers, irrational numbers, and transcendental numbers. But we're somehow ok with all of those.
(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.
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.
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.
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

There's actually a funny story here, and one day we'll tell it in more detail.
TDLR: it's a coincidence / slightly obvious given our names. We discovered the similarity on the day we launched our logo, and it almost made us change our logo and/or company name XD
We have since met the getstream.io folks and had a good laugh about it together.
What always bugged me about QR codes is that they're not human-readable.
I'd love if there were a standard where you'd simply have a human-readable URL plus some markers at the start and end to help with OCR. And you could standardize the font too.
This was a big deal in some academic circles in the early 2000s
