These days, even phone-class CPUs can decode 4k video at playback rate, but they use a lot of power doing it. Not reasonable for battery-powered devices. For AC-powered devices, the problem might be heat dissipation, particularly for little streaming boxes with only passive cooling.
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.

Audi's with Torsens only lock front-to-back (but then so do a lot of 4WD vehicles). They use brakes to stop slipping wheels so the other side will get torque. A long time ago, they had lockers for the rear for low speed use.
Yes I did. It definitely caused some nausea for me when taking on an empty stomach, but taking it with even a small amount of food seemed to eliminate that entirely.

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.
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

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 ?
Someone made a website showing which airlines have the most delays, so airlines just added an hour of padding to every scheduled flight, and then fly slower / burn less fuel when there aren't delays. We do the same thing with commuter trains. Someone was mad that they were late to work one day during a snowstorm or something. Now trains with a top speed of 80mph take 80 minutes to go 40 miles. But are on time 99% of the time! Look at all the time saved from not being late to work!
Personally, I'd rather be 4 hours late to work once a year and save 1 hour commuting every day. But the masses have spoken and decided the opposite. I work from home, so not my problem, I guess.
Japan is better than the US, but I've definitely been standing around in Shinjuku station waiting an extra long time for a train, freezing my butt off, while the signs scroll "because of heavy snow in Gunma prefecture, trains are running with 15-30 minute delays." Weather is weather.
My favorite US-ism is when Andrew Cuomo (the governor of New York at the time) shut down the NYC subway because of a forecast of 24" of snow. The reason the subway was built was because of the transport disruptions caused by a big snowstorm in 1910. To close it for a snowstorm was the ultimate irony. The snowstorm didn't materialize and he looked like an idiot. The MTA then developed an actual service plan to keep the subway open during snow, and it hasn't been a problem since. (Well, not for me. For people that live on non-underground lines, they are probably annoyed. I think the pre-Cuomo policy was "play it by ear and hope for the best". That was rarely ideal but probably let a few people get home from work before trains started getting stuck. Now nobody gets stuck, but they also get stranded when the snowstorm ends up not being bad.)
Has NYC even had a comparably large snowstorm since then?
The reason Cuomo pre-emptively shut down the subway was because a few years prior there had been a serious snowstorm that did severely disrupt subway service. He was trying to avoid a repeat of the same scenario. It turned out that the weather forecast was wrong, but if we actually did get 2 feet of snow and the subway was up and running the next day, with nobody stranded in tunnels or on bridges, he would have looked like a genius.
Cuomo did a lot of stupid stuff (e.g. spending millions on pointlessly renaming bridges and setting up illegal highway signs), but that particular move was not one of them.
> The MTA predicts that over 12 inches of snow or blizzard conditions could cause “significant service suspensions” or a full system shutdown. However, before that, there are several contingency plans in place for winter weather and extreme snowfall.
> Has NYC even had a comparably large snowstorm since then?
14 inches in 2021.
> To this day, the MTA says that over 12" of snow would still result in system disruption and service suspension
I think the MTA's "underground only" service plan is fine: https://new.mta.info/map/9471. This popped up right after the big shutdown. I don't see why 12" of snow would have to go to a full shutdown, unless MTA employees can't get to work. (I don't know how likely that is.)
Maybe we'll find out tomorrow! (I'm personally placing my bets on "100% rain".)
(Edit to add: apparently we got 27 inches of snow on 1/23/2016 and all underground subway service ran. I have absolutely no memory of this. I might have been in Vermont skiing.)
New York's snow woes really surprise me. I grew up in the suburbs of Chicago and really only ever heard about snow days on TV. We would get 3 feet of snow and still have to be at school the next morning. Every winter, I dreamed of the "phone tree" being executed. I learned the weather patterns that would result in a lot of snow. I looked at the weather page in the newspaper every day, and glued myself to the TV after school if it was looking good for snow. A few times a year, I would get really excited. It was looking like a big one. I'd stay up late and look at the snow piling up on our deck. Higher than I'd ever seen! The next morning I'd wake up and turn on the local news and watch the list of school cancellations, as my parents got ready to go to work. Never mine. Not once. I think my parents would usually drive me to school, though, which was nice.
So I guess I'm just surprised how in New York we just shut down the city upon the forecast of a couple feet of snow. Maybe it's necessary at scale. Or maybe we're just wimps.
> Cuomo did a lot of stupid stuff (e.g. spending millions on pointlessly renaming bridges)
I guess the issue is that the yards where the trains are stabled are all above ground. If you can't get the crews to them, inspect, and operate them safely, you can't get them in the tunnels. Subway trains are all also 3rd or 4th rail powered, so I can see how lots of (effectively) standing water makes people nervous.
The mitigation I suppose would be to get them underground in advance, and when/if the snow hits you just run with what you've got.
In NYC we actually have a bunch of yard capacity that is completely underground, and then a bunch of other yards that are covered (like condos built on top). Typically the snow service plans involves stacking as many trainsets as possible on the express tracks, while service runs on the local tracks. There are a ton of extra express tracks on the network (because the IND had what appears to be unlimited money when building their system), so capacity doesn't suffer a ton.
Honestly, in the 12 years I've lived in NYC, there have really only been 2 or 3 nasty snowstorms. Generally things ran OK except the one time Cuomo freaked out. (Hurricane Sandy was pretty nasty, of course. Rain and storm surge are much worse than snow here.)
I mean, yes, of course, weather is weather. Nobody expects perfection in the face of force majeure. US railways, however, seem to specialize in delivering the minimum possible experience that doesn't result in open riots.
Less about carbon footprint and more about fuel costs, IIRC; passengers are generally more cost-sensitive than time-sensitive, so if a plane can only hit mach 0.8 (or even worse) but has better fuel economy at the relevant speeds, that's better for the airline.
Airlines found out that people, in aggregate, care more about ticket prices than about speed. Flying a bit slower allows planes to be more fuel efficient, and thus allows them to offer lower ticket prices.
I wouldn't be horribly surprised by a Boeing breakup, honestly. Even BDS might splinter down into smaller units.
The real question in a Boeing breakup, IMHO, would be what happens with BGS, because the org as a whole does an insane amount of hide-the-salami with repair/return/rebuild.
The problem is not the values delivered to the DAC. It's the aperture error of when the DAC was clocked. This affects what those sample values actually represent. If the clock is being extracted from the pattern of pits and there's a way to reduce the jitter, you will get a more accurate signal.
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.
Things have improved a whole lot since then. Used to be that as soon as you opened any app, it just requested full admin access to everything. Now its that you try to share the screen and you get a popup asking if you want to allow sharing the screen.
It's actionable now. You can use an app without allowing the permission request, and the permission request is tied to when you try to use the function rather than at install time or app boot.
