are these videos larger than the iphone SSD or TB SSD DRAM buffer and will need to drop to NAND erase/write speed?

isnt that how the modern telephone system works? digitize your voice, encode, transmit, decode, convert to analog audio. with buffering or keeping bits in memory all along the way?

is a telephone call a recording?

from the video I thought the wearer had to enable it, just as today where the wearer has to enable the audio recorder app.

its not unheard of for large public companies to do spinoff. a few examples that seem to have worked out fairly well

Phillip Morris / Altria / Kraft / Mondelez

HP / HPE / Agilent / Keysight

I assume for something like a phone these things are non-linear. going from 2 PCIe lanes (nand, radios) to 3 (another radio) may cause an SOC to jump from entry-level to mid-level, larger PCB and increased layer count, more antenna for simultaneous use, etc. so its not just the cost of the chip but all the secondary effects.

I think the Rd pulldown options are for 0.9/1.5/3A without PD negotiation.

> Grocery stores have very small margins, as little as 1%.

Looking at the Kroger 2024 Annual report shows that they have 22.3% gross margin . they pay dividends, had a stock buy back, etc so its entirely possible that they had a very low margin but gross margin seems to be similar to a home builder.

Sales $ 147,123

Merchandise costs $113,720

Rent, Depreciation, Amortization $655

Gross profit $32,748

for a gross margin of 32.7/147 = 22%

> certain cables won't charge certain devices

not sure how you can make a cable that doesnt connect power from end to end. I can see if it doesnt charge as fast as others if it doesnt have the bits required for higher current support. and if a device requires >5V to charge, thats on the device not the cable.

> other cables won't transfer data

again, not sure you can make a cable that doesnt connect the USB2 pair from end to end. but if device doesnt use USB2 and requires something else without mentioning it then that again seems to be on the device not the cable.

> Year over year price hikes with minimal improvements

did you have a specific example in mind? It seems that the price of the hardware generally stays the same from year to year.

for example, from iphone 3g to iphone 6s was $199. and iphone 12 through today's iphone 17 is $799. I think the change in the middle was due dropping carrier subsidies and going to full-screen with face id.

> 1000Base-T uses two pairs per direction, actually. It's full duplex. Each port sees two TX and two RX pair.

you may be thinking of 1000Base-TX (TIA‐854) which uses 2 pairs in each direction, similar to 100Base-TX (IEEE 802.3u). whereas 1000Base-T (IEEE 802.3ab) uses all 4 pairs in both directions.

basically, the -TX are dual simplex with a set of wires for each direction and -T are full-duplex with the same wires used in both directions at the same time.

> For example, consider a president who dies in office a few days into the term. The VP becomes president, serves out the remainder of that four-year term and then be elected for two more terms

text of the 22nd amendment covers that. serving more than 2 years of someone else's term means you can only be elected once.

Section 1. No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once.
