While I agree that setting up separate repos for subprojects is a good idea, I don't see any need to leave them out in the BDFL's GitHub account. Not only...

Add Braille Glyphs

3

[htop](https://hisham.hm/htop/) uses glyphs from the [Unicode Braille Patterns](https://en.wikipedia.org/wiki/Braille_Patterns) block, but it seems that Source Code Pro doesn't have these. Could they be added?

Probe can't find /usr/include/SDL2/SDL_ttf.h

17

On `5506d39a2`, the current head of `master` as I write this, `configure` on my Debian 9 system fails to find only one library, `SDL2_ttf`. The relevant lines in `probe.log` appear...

HTTP_PROXY et al. Environment Vars Not Supported

3

Unlike [`requests`](https://pypi.org/project/requests/), `treq` doesn't support the (semi-standard) environment variables for proxy configuration, such as `HTTP_PROXY`, `https_proxy`, `no_proxy` and others. This makes it unusable in some applications, such on company networks...

Clarify "reference" in filters for `docker images`

1

This is possibly related to (though not the same as) #1332, "docker images --filter=reference giving seemingly unpredictable results." It's a copy of issue [#7618 in docker/docker.github.io][7618] which was just now...

Default to input() instead of getpass() to fetch MFA credentials

6

Currently in `botocore/credentials.py` class `AssumeRoleCredentialFetcher` the default `mfa_prompter` is [`getpass.getpass()`]: self._mfa_prompter = mfa_prompter if self._mfa_prompter is None: self._mfa_prompter = getpass.getpass This is unusual in that MFA authentication user input normally...

Why is the peripheral clock (φ2out, bus pin 23) separate from the CPU clock (φ2in, bus pin 21)?

6

The 6502 has a φ2out pin (39) to allow access to the system clock when the internal oscillator is used. This doesn't seem necessary if an external oscillator is used...

In [PDF schematic for the Debug board](https://github.com/tebl/RC6502-Apple-1-Replica/blob/master/RC6502%20Debug/export/RC6502%20Debug.pdf), the `SYNC` signal has a directional indication that it's an ouput from the clock input of the 74LS74 to the bus, but in...

The [`map_to_ascii()`][map] function in pia_communicator seems to be at least partly nonsensical. It's passed the output of [`Serial.read()`][read], which returns a byte read from the serial port. An examination of...

The control character output handling of the PIA communicator is [substantially different from the actual Apple 1][sedoc]. Here is the original Apple 1 behaviour: * ASCII Control characters ($00-$1F) other...
