Huh, I just learned that apparently ϕ is shorthand for diameter?
Oh, wait. I get it. Because it looks like a circle.
Except this installation manual I was reading was using φ! That doesn't look like a diameter anymore.
Engineers, I have questions.

С развитием сетей 4G и началом развертывания 5G в России протокол `Diameter` стал важнейшим инструментом для современных телекоммуникационных операторов.
`Diameter` используется для:
- управления доступом в сети LTE/5G,
- аутентификации пользователей и устройств,
- реализации биллинговых систем и учета трафика,
- поддержки качества обслуживания (QoS).Кроме того, Diameter активно применяется в системах управления политиками (Policy Control), которые позволяют операторам предоставлять персонализированные услуги на основе потребностей абонентов.

»Während er über die Kyjiwer Autobahn rast, tippt er auf seinem Telefon und erzählt von der Operation "#Diameter". Es ist eine lange Geschichte. Später werden andere Quellen die Erzählung ergänzen und Lücken füllen.
„#NordStream war ein militärisches Ziel“, sagt der Mann. Ein legitimer Akt der Selbstverteidigung, so sieht er das. Deutschland, das wiederholt er, habe man nicht schaden wollen. Die Pipeline sei eine Geldader Moskaus gewesen.«

Today’s #APOD is not a #photography but an #artist view of the #dwarf #planet #Makemake (pronounce MAH-kay MAH-kay) and its #moon to scale. Makemake is really a dwarf planet, it is only ~1430km (888 mi) in #diameter, hence 41% of the size of the #Moon, and 60% of the size of the dwarf planet #Pluto. Both dwarf planets are actually smaller than the #Moon.
