It had never occurred to me that, during a shortage, the most expensive products would sell out last. It makes sense now I've seen it happen, but I've always associated food shortages with austerity - instead I'm suddenly buying premium organic free range duck eggs.

This is because this is not an actual shortage. This is people panic-buying things they don't really need, and then of course they can't justify spending that much...

And the coronavirus was just a flu. And there's pent-up demand in out economy which will just explode when we get out of this.

No. This is not panic-buying or hoarding. There are actual supply chain disruptions, shifting demands, fewer workers going to work, and things just aren't keeping up with major disruptions to economic structures based on low margins, having just enough capacity, and doing everything just-in-time.

They're addressable, but we're not addressing them. Instead everyone tells themselves pretty stories about how the problems aren't real, and everyone else seems to believe it.

As far as I can tell, no one actually keeps an eye on these things either. We have no idea if we will have too much or not enough food in 6 months, and my guess is not enough (B2C producers aren't scaling up due to pretty stories, while B2B ones are shutting down due to lack-of-demand).

Average is meaningless. Either you have broadband and you're physically capped at 1 Mbps upload, or you have fiber and it's -roughly- unlimited. The average of 9 households having broadband and 1 having gigabit fiber may be 100 Mbps theoretically, but practically that's 9 people who can't use a HD webcam.

Which part do you need more explanations about? I find modulation a fascinating topic.

Broadband ADSL has a total usable bandwidth around 20/1 Mbps due to how it works, that goes down significantly as a home is further from the phone center. Many homes won't get any better than 5/0.5 as they're kilometers away.

A single fiber can do a Tbps both ways. The difference is night and day.

The part that ignores the existence of cable internet? Or the fact that plenty of people are on cell phones for their broadband usage?

The available options are more than "DSL, fiber, or nothing".

The webcam and video call market has stopped to improve like, 10 years ago. There's some exceptions, like the Brio, but they are worse and more expensive than a whole cheapo phone with 2 cameras. Overall we're mostly stuck with 1280x720 fixfoxus usb-2.0 crap. On the software side, things don't look better: UVC 1.5 finally does support hardware encode with bitrate control, but software support is scarce. Completely un…

The Meeting Owl Pro appears to be an exception to the innovation complacency. https://www.owllabs.com/meeting-owl

$1k webcam?

And standing desks. I've been trying to source some for my business (to retail) and all of the cheaper models are sold out. The models we have been able to source are a harder sell at their price point. https://www.elementrelocations.com.au/work-from-home

Just an idea, would it be possible to use plumbing pipes or construction scaffolding instead?

One of our customers uses his ironing board; he put it next to his regular desk.

Some of the first consumer level usb 3.0 webcams capable of 60 fps only came out a few years ago. Before that it was impossible to get such framerate on a webcam because usb 2.0 did not have enough bandwidth.

Personally I’d put a higher frame rate near the bottom of my wish list for a better webcam. First, improve low light performance, autofocus, white balance, dynamic range, and autoexposure. Once those are good then we can talk about frame rate and resolution....

HDR in particular is a feature sorely missing from webcams, where it seems everybody is being darkened by a nearby window.

It's incredibly annoying that you can't use your APPLE iPhone camera as a webcam for your APPLE Macbook, but instead are forced to use the atrociously terrible cam that comes with the Macbook. I've tried workarounds using the excellent OSB, but there's currently no software that let's you reroute video on a Mac (like Loopback does for audio) EDIT: I stand corrected, as user wolfhumble points out below, EpocCam seems…

If you are ok with a MacBook screen nearly as thick and heavy as an iPhone, you can have a better camera. The increasing thinness of modern laptops has come at the expense of improving their cameras.

I don't understand how Amazon has not shut this down. I went to buy one a month ago and it was already at this piratical price. Don't they actively prevent price gougers when they find them?

I guess it’s human nature to prefer there be no webcams available at all, than for one to be on sale at a high premium.

Not sure where you're living but that's not true. Home broadband has gotten a lot better over the last 10 years here in the UK. I don't know anyone (admittedly I don't know many in the countryside) who can't stream at 1080p. Even 4K Netflix is often fine.

He's referring to upload, not download, since that is the relevant metric when talking about using a webcam.

That still depends on where you are. Don't assume that the rest of the world is like America.

Here in South Korea, 100M symmetric is the bare minimum. For just a few dollars more, you can upgrade to an "up to 500M" plan that usually provides something like 300M symmetric. Often, upload speeds are even faster than download speeds because there's less congestion in that direction.
