DC connectors used by APC :Anderson Powerpole – Wikipedia
Posted by jpluimers on 2021/01/29
Different keying for each colour in the SB50 series. Note that black and grey are keyed the same making them interchangeable.
I bumped into [WayBack] Anderson Powerpole – Wikipedia through Cheap VS Expensive Solar Panels | 12v Touring | Project Cyan – YouTube.
APC uses some of these connectors (I have seen the yellow, blue and grey ones) in many of their systems: [Archive.is] apc battery connectors – Google Search
Images from wikipedia.
Quotes from the article:
Powerpole connectors are physically and electrically hermaphroditic, thus avoiding the need to worry about which end is the plug and which the socket, or which end has the correct polarity.
…
The Anderson Powerpole connector is more expensive than the older de facto standards of the two-wire trailer plug and the Molex connector, but provides a more reliable electrical connection (both mechanically and electrically), and is easier to adapt to a wider range of wire gauges.[19] Another advantage over the older trailer or Molex connectors is the Powerpole’s superior ratings to withstand 100,000 no-load insertions and 250 hot-plugs at full load. The specific hermaphroditic nature of the powerpoles is a significant advantage since batteries can be both a power source or a power sink, a power supply can be connected to a radio and/or a battery, and multiple batteries, radios, and/or redundant power sources can be connected in parallel using the same power distribution panels.
…
For use in amateur radio, the community has adopted a standard color code, polarity, and specific physical arrangement for assembling pairs of Powerpole connectors. One red and one black powerpole housing can be physically arranged in 4 topologically different mechanical orientations (red left, red right, red top, red bottom – when viewed from contact side with tongue up), 2 of which are mechanically incompatible (connectors won’t mate with ARES) and 1 is electrically incompatible (will mate but reverse polarity) with the ARES standard; there are also additional unusual configurations in which one housing is rotated 90 degrees. The standard is red positive and black negative. When viewed from the contact side, a mnemonic for remembering the arrangement is: “Red [on] Right — Tongue [on] Top” (note the first letter alliteration).

Detecting what language or script a run of text is written in, redux – The Old New Thing

Interesting: [WayBack] Detecting what language or script a run of text is written in, redux – The Old New Thing.
Do not confuse language with the scripts in which one or more languages can be written, and much more is covered in it.
