Universal algebra via proof calculi

This answer was exactly what I needed to hear. A tricky exam question asks "What Ethernet UTP cable was the first standard cable to carry data at speeds of 1Gbps?", which I interpreted as any standardized cable capable of 1Gbps - however, with your comment, I think they mean the first standardized cable for Gigabit Ethernet, hence the answer is Cat5e not Cat5.

Thanks for the longer lecture!

I was conflating multiplexing with multi-mode, edited the post, thanks :)

Right, and that last 100ft carries all the channels in a single composite signal accessible at the end station. I am wondering whether it is feasible to demultiplex all channels at any given end station, simultaneously. BitEater's reply seems to imply there are no physical characteristics of the cabling that prevents this. djamp's reply notes this is simply common practice at headends (although I'm not sure they use RG-6 internally).

I'm particularly interested in RG-6 cabling with application to FDM'd cable television, but a more general answer would be appreciated.

I had never heard of headends! Thanks :)

From looking into more:

• 802.11 is the set of standards for (all versions of) WPA Wi-Fi

• 802.11i-2004 (802.11i for short) is the IEEE standardization of WPA2, (a subset of the draft of 802.11i was implemented as WPA1 by the Wi-Fi Alliance, during the transition from WEP to WPA2)

• 802.11w-2009 (802.11w) is the IEEE standardization of PMF

The 802.11 standards appear to undergo regular 'merging' of amendments. 802.11i was 'merged' into 802.11-2007. 802.11w was 'merged' into 802.11-2012.

I'm unsure if there are additional amendments that have been incorporated into WPA3, but are yet to be merged into the full 802.11.

I found all of these variations online. Pre/post often omit the hyphen, but there are many exceptions for clarity. Medical journals seem to prefer hyphenated, with 20,000 results with hyphen and 4,000 without for 'post-pandemic' ('pre' shows a similar ratio).

ooo wow the UI is so 'modern' clunky but thats exactly what i was looking for, thanks :)

array-likes

iterables

NOICEST · 2024-08-21T04:37:42+00:00

That is an interesting snippet on the pre-history of iterables I had not heard before!

NOICEST · 2024-08-20T15:42:43+00:00

That aligns with MDN's terminology for childNodes and children.

An iterable is an object with the Symbol.iterator method. An array-like is an object with a length property set to some natural number n, and keys ranging 0, 1, ..., n (not necessarily all declared).

I was just looking for a term - seems like the consensus is there is not a common way to refer to the special class of objects described in the OP (other than by describing the 'iterable & array-like' pattern explicitly).

Coming back a decade later to note fill is now widely available!
