@NiklasMM @JennyFluff @kevin yep. They're all dry cells. A 9V battery is just 6 AAAAs wrapped in a rectangular package. @JennyFluff @kevin literally had a discussion about this yesterday after someone from our assembly went to the Media Markt for AAAA batteries for a tablet pen 😂 @eloy @JennyFluff @kevin @kevin TIL that A and AAAA are actually both: https://en.m.wikipedia.org/wiki/List_of_battery_sizes @kevin AAAA is also a battery believe it or not. They aren't used in a lot of consumer electronics, but you'll find them hidden inside a few things, often soldered in. I've seen a few mini remotes for various devices (not TV remotes) that used them though. Also, these days manufacturers are so cheap that you'll also find them in most 9V batteries. They literally just wrap up six metal cased batteries with another metal case so you can't tell. @kevin This naming scheme for DNS actually comes from the fact that DNS Records are written in these said batteries and these batteries are then placed into the nameservers. right? @kevin so AA and AAA batteries are therefor two and three times respectively the size of a single ipv4 address size (32 bits). This makes so much sense, thanks! It blew my mind when I discovered when my ISP started to support IPV6 they gave me a /48 prefix, this means (quote) '[it] contains 2^80 addresses, being 2^48 or about 2.8×10^14 times larger than the entire IPv4 address space of 2^32 addresses... 🤯 @kevin Aren’t they all dry cleaning or automobile towing businesses in the local Yellow Pages directory? @neilo My father used to work for a company that repaired TVs and other consumer electronics (decades ago, when people still did that). It was named A-Amphi TV, for the same reason. @kevin AAAAA : Association amicale des amateurs d'andouillette authentique (Friendly Association of Lovers of Authentic Andouillette) I accidentally ordered AAAA batteries once. I still have them. Never seen thing that takes them. @kevin my Surface pen takes AAAA batteries. I didn't know they existed until it died and needed a replacement. @kevin AAAA is also a battery: https://en.wikipedia.org/wiki/AAAA_battery @kevin@mastodon.km6g.us everyone is saying how AAAA is a battery but I think A is a battery too, just even less common than AAAA @kevin believe me or not, my brain just clicked on this memorization tip last week. After years trying to find a way... @kevin don’t forget: Then skipping down a bit: Well... this toot blew up a bit, and for the first time I've seen the actual 'fragmented reply view' problem that lots of ActivityPub people have been talking about. I got seven replies mentioning that AAAAA is the French andouillette society, and there's a pretty strong chance that none of the people who sent those replies could see the other ones as they were all sent from different instances. |
@kevin but AAAA can also be a battery
