"5000 Erlangs" - oh, they meant 5000 instances of some Erlang interpreter.
Not Erlang as a unit of measure.[1] One voice call for one hour is one Erlang.

- lawik 1y agoI was aware an Erlang being a unit though I'd forgotten what it measured. I Need to have my fun when giving titles to these things. Hope it fell within bearable tolerances.

- robocat 1y agoWhat does 5000 Animats measure? Does 1 Animat convert to metric nitpicks? You know you're successful once you're added to: https://www.theregister.com/Design/page/reg-standards-converter.html https://www.theregister.com/Design/page/reg-standards-conver...

- QuantumNomad_ 1y agoNeat! I always thought the name of the Erlang programming language just meant “Ericsson Language”, since this programming language was invented for Ericsson. Never knew there was anything more than that to the name!

- RossBencina 1y agoI believe it's neither: "The origin of queueing theory dates back to 1909, when Agner Krarup Erlang (1878–1929) published his fundamental paper on congestion in telephone traffic [for a brief account, see Saaty (1957), and for details on his life and work, see Brockmeyer et al. (1948)]." -- https://www.sciencedirect.com/topics/engineering/queueing-theory https://www.sciencedirect.com/topics/engineering/queueing-th...

- Animats 1y agoIn the early days of telephony, system load was measured by how much current was being drawn from the talk power supply. This was done with a watt-hour meter, calibrated in erlangs.[1] (It's amazing how little logging went on in the phone system before computerized switching. But that's another subject.)

- RF_Savage 1y agoAnd it was a pun by Ericsson engineers, as they used Erlang to program telephone switches where the capacity planing included Erlangs.
- lawik 1y agoAccording to Robert Virding at an unnamed bar in Berlin ~3 years ago they just wanted to be like Pascal in terms of picking a mathematician. But Ericsson Language certainly helped sell it internally, I'm sure.
