There are better separators included in ASCII, but not used as often: 28 File Separator, 29 Group Separator, 30 Record Separator and 31 Unit Separator.

Isn't iframe the replacement? iframe is not deprecated.

I'm planning to do something similar, but using addressable RGB LEDs (like WS2811, also known as neopixel).

They are simple to work with. Each LED has 4 connections: GND, +5V, DATA IN and DATA OUT. Each LED grabs the first 24 bits of the data stream (8 bits for Red, Green and Blue) and sends the rest on DATA OUT for the next LED.

There are few well-documented standards. There are ready-made solutions that have worked for decades. What do you think AI would add?

I sometimes use them for machine to machine transfer. The biggest problem is that regular editors don't handle it in a sensible way.

The phantom power at 48 volts used with XLR connectors only have a current at about 10 milliampere. Enough to supply power to a little microphone.

The connector is bulky and of metal, and designed to be used inside. It's also expensive compared to other connectors. There are a lot of cheaper, more suitable connectors, designed to carry power.

Depending on the country you live in, the laws might allow you to do work on equipment that is below 50 volts, but require you to be a certified electrician for anything above that.

> appending things to arrays etc can't be done elegantly

Are you referring to the possibility to point to the end of the array? If so, a single minus sign might solve it: "/path/to/the/array/-"

RFC 6901 JavaScript Object Notation (JSON) Pointer > exactly the single character "-", making the new referenced value the (nonexistent) member after the last array element

All vehicles that can be steered have that possibility, even cars: If there is a steering wheel, it is possible to deliberately crash the vehicle. If it is possible to shut down engines, it can also be used for malicious purposes. In other words, there is always the possibility of using everything for malicious purposes.

On the other hand, the ability to shut down a system that has failed can save everyone on board.

There are approximately 40,000,000 flights each year. Almost all occur without incident. In the entire 120-year history of aviation, only a few accidents have resulted from the pilot intentionally crashing the plane.

A quick search shows it in the documentation for version 8.4, released July 1, 2009.

Maybe 15 years is "somewhat recent feature". :)

Remember that ASCII is short for "American Standard Code for Information Interchange".

base64 was proposed in 1987 to work with ASCII, EBCDIC, and other character encodings.

No need to change the system clock for a millisecond. The operating system has an API for changing allt the timestamps of a file.

Remember to first punycode the domain part of an email address before trying to validate it, or it will not work with internationalized domain names.
