Edited to add that I think EPMs are under more pressure to be Apple cheerleader than engineers.
A “carry” or “live on” device doesn’t have to be used for personal email and messages. It should just be used for more real-world non-test workloads. The lessons of only testing iPhone 4 in stealth cases hasn’t been forgottten.
I do agree that Apple likes to have it both ways, though.
but long after The Prince was a thing.

Apple can afford to do test fabrication while abiding by the rules, but chooses not to. https://www.sfgate.com/tech/article/apple-fine-over-bay-area...
This page https://obsproject.com/forum/resources/capture-card-document... warned me about it, but I haven't seen any updated info on the newer AVermedia or Magewell interfaces, for instance https://www.magewell.com/products/usb-capture-hdmi-4k-pro This gives 4k60 4:4:4 only on the loop-thru output, higher resolutions require 20GBps USB 3.? but my Mac only goes to 10. I'd need Thunderbolt capture which start around $1000 https://www.bhphotovideo.com/c/product/1500555-REG/blackmagi...
I'm using an Elgato CamLink 4k at 1080p60 for now & I'm wondering if the awful mouse feel in Linux (with a Mac for display) is maybe due to delay. Going to get a cheap-ash monitor to simplify. I thought it would be nice to have my 6k Pro XDR display have windows from all computers, but it's just too messy.
Worked on DEC Alpha, AMD K7 & K8, Broadcom, P.A. Semi, was in turn purchased by Apple. Jim spent four years at Apple before first returning to AMD, then on to Tesla, Intel and finally Tenstorrent.

No more detail on this, but it was huge for MIDI not to end up "becoming a nightmare of endless fine-tuning better suited to electronics engineers than musicians" like CV/gate was.
https://midi.org/midi-history-chapter-6-midi-begins-1981-198... spells it out in more detail:
Mieda-san from Korg responds on behalf of the Japanese companies to the meetings at the 1981 Gakki Fair with Sequential and Oberheim and confirms the discussion that were they had at the Gakki Fair.
• 19.2kbps is too slow
• ¼” Jacks will have ground loop problems
• There is no concept of synchronization, clock or the ability to start and stop sequences

Ground loops are the bane of musician's lives and sometimes the mitigation is the end of their lives
"Boeing Military Airplane Company; Hughes Satellite Systems; Hughes Helicopters minus the civilian helicopter line (which was divested as MD Helicopters); Piasecki Helicopter, subsequently known as Boeing Vertol and then Boeing Helicopters; the St. Louis–based McDonnell division of the former McDonnell Douglas Company; and the former North American Aviation division of Rockwell International."
making it not just too big to fail, but too important to US and allies' defense to fail. I guess defense could be split from commercial aviation which could be reduced to producing parts to keep fleets in operation until Airbus can replace all planes over 30 or 40 years. Some of McD-D's commercial planes have a second life as military, though, e.g. the P-8 Poseidon based on the 737-800.
I took a couple of cross-USA flights recently, some on 737-800 and some on 737 MAX 8 and noted that the 800's cruising speed is faster (cf. United's Hemispheres magazine). I suppose the carbon footprint of the MAX is lower, but whatever happened to flying at mach 0.9 ?
However, I'd hope that anyone that cares about fidelity has a CD player that does a little more to generate a DAC clock. NCO run by a software PLL or a hardware PLL with a good loop filter are things I've heard of, but control systems is not my specialty.

It's not just the GPU that shares memory with the CPU. The "media engine" buffers are in there, too at 18 megabytes per frame for 4k reference pictures in the decoded picture buffer. The decoder, scaler, GPU, and DRAM are fast enough to have several tracks of 4k (which even the iPhone 11 & SE can shoot), so don't let RAM size be your limit. I'm happy to see a max of 24GB vs. the M1's 16GB.
I have an Apple Pro Display XDR and it's just not worth the hassle trying to use it with Linux or Windows machines. Instead, I plan to use an HDMI capture device to get 1080p windows on a Mac. OBS's [guide](https://obsproject.com/forum/resources/capture-card-document...) shows some devices that capture RGB at 1080p60 like the $170 AVerMedia Live Gamer Ultra (GC553) and $300 Magewell XI100DUSB-HDMI. Uncompressed 24bpp x 1920 x 1080 x 60 is almost 3 megabits/second, so OK for USB SS, but not great for networking over a distance, but my application doesn't need remote.
My son was able to book the last 2 seats on a Southwest flight so we only lost a day of a $500/night AirBnB. Luckily, my son uses gmail so we got the confirmation w/ a check-in link OK. We lost our car rental reservation because Alaska's idea of a replacement reservation arrived 32 hours later and Budget only holds for 24 hours. Even the SWA was 26 hours later, but somehow Priceline + Thrifty found a car.
So a shitshow could have been even worse if the 2nd outage had started earlier & my kid had taken my advice to de-google. My sister & parents also use Fastmail due to my advice, but aren't as dependent on timely email.
One thing that did save me is that I brought a notebook which has all my old email. Almost left it behind, but it's 2.8 lb & 1.61 cm thick. Smartphones still have their limits....
"While most airlines do not have a firmly defined maximum number of batteries under 100 Wh that can be brought aboard, we'd suggest travelling with no more than 4-5 LiGo's per person in order to avoid extra scrutiny. We have had customers travel by air with as many as 12 LiGo modules on them, but we wouldn't recommend that as a matter of course."

The Grin Technologies motor simulator https://ebikes.ca/tools/simulator.html predicts (the "Load Line") 837 Watts for "MTB upright", 648W for "MTB, Tuck" and 570W for "Road, Tuck".
I do find that in an upright position it takes 100-200W of human power in addition to 750W power measured at the input to the motor controller. The controller's pretty efficient, but the motor (GMAC) is only 85% max, so there's maybe 570W at the axle. The US CPSC and California laws aren't clear whether the 750W/1 horsepower limit is power in or power out, but power in is what shows on the display, so I limit it to that. Also, even a mild grade will cause the motor to approach the 70 deg C limit I chose after 1 minute. I live in the flattish Santa Clara County, but I'd definitely want a mid-drive if I lived in a hilly area. A 250 or 350W Riese & Müller Delite https://www.r-m.de/en-us/bikes/delite/ I test rode needed a lot of human power to hit the 45 kph max, but it climbed hills in Larkspur like a goat.
750W will have no problem getting a recumbent bike to 30MPH, but don't count on it for an upright.
