If you’re the typical hacker news reader, I suppose there’s a good chance you have a decent quality SLR or mirrorless camera. If it has a clean HDMI output, you can use it with a capture card (80USD or so) on amazon and you’ll have the best webcam money can buy. Couple that with a cheap lavalier mic or similar and you’ll have far better quality than any video call is likely able to transmit. If you’re feeling really…

During a crisis the primary goal is maintaining societal stability. Exploiting the rich and the desperate deteriorates that stability. People would rather have a lottery than an auction in these scenarios.
I presume a shortage is far more destabilizing for the most essential things than a higher price. Plus the government can act as a central buyer to back those who have the greatest needs. That and companies should be responsible for providing protection for employees
Why shouldn’t the price increase with a supply chain disruption and demand boom? Would you prefer a shortage with no incentive to increase production?
If I used to produce 100 units per month because that's how many I could sell, but now I know I can sell 10000 units per month, that is incentive enough to increase production. Notice here that raising the price is not at all required to increase profits. It's just something companies tend to do because they know they can get away with it in high demand markets. And since raising prices to increase profits is not nec…
And more to the point: you have no idea. Prices are emergent from trillions of decisions, and are used to communicate a great deal of information. People want to act like it's an engineering problem where we can dial up and down one part without affecting other parts, but anyone who has worked even on a controlled marketplace knows this isn't true.

I've had huge success with IP Webcam, especially since it appears to be a standard MJPEG stream, so very hackable (in the good sense). The web interface also crucially adds UI for focusing, in addition to the customizable in-phone UI.
I've not been able to get it to work smoothly without specifying at least a 1000ms buffer, which kinda ruins the ability to use as a real time communication tool. Gigabit local lan, strong wifi N MIMO signal, Galaxy S10 and a fairly recent Macbook pro (dual booting to Win 10). Have you encountered a similar hurdle?

People started hoarding out of hysteria. Which creates shortages for no reason. Which drives the prices up for no reason. Which benefits and encourages hoarding. Which encourages yet more hoarding out of speculation. Which means resources needed at this instant are instead sitting idle, at best awaiting higher prices at some arbitrary future date. And earnings, rather than going to producers, are wasted on pointlessl…
@TomMckenny, is there a resource that speaks to this economic theory of yours? Because the sources I cited here: https://news.ycombinator.com/item?id=22815572 reflects mainstream economic theory and what I have learned in my economic courses at university.
I can't know what was said in your classes. Assuming no control on prices in a crisis, did they say how holding a large stockpile of a rarely needed item for the long term with it's associated storage cost and risk is in some way more profitable than simply cornering the local market on the commodity at the time it is needed and indeed helping those prices rise rather than fall? In honesty, that may be a hidden assumption against price gouging more than an ideal market example used in a classroom.
At any rate, few if any mainstream economists suggests that sudden monopolization of emergency commodities that are needed immediately but briefly during a crisis would be remotely a good thing. It is more a Cato institute / libertarian position driven by ideology rather than real world data and history which consistently refute it. It is also why no sane society allows it in emergencies on crucial goods.
As if to prove the point, the theory has just been tested yet again: there are no world wide government price caps on toilet paper and yet there is an enduring shortage at the moment.
If interested in this, here is a Nobel prize winning economist writing right now on the issue:

Apparently you don't have a dog or a child :) I cannot stress enough how (especially) a standing desk needs to be super sturdy with children/dogs in the vicinity!!!

Great write up. I agree I do not trust them very much and would not use them on a network that has internet access. They are a great cheap option when using their custom RTSP firmware with synology surveillance stations. I throw them on their own SSID that is isolated from other local networks and does not have internet access. The SS can reach into their network but they can't initiate connections out. Still they br…
I don't think that was a great write up. I'm no panda-hugger but I was hoping for evidence/walk-through for the following claims made in the article, and I didn't find any direct evidence in the article. Did I not read it closely enough? (Pretty sure the claims are made without support) > Yi Camera is a front for the Chinese Ministry of State Security. Full stop. > Yi Cameras send all customer data to Xiaomi as I hav…
Honestly I’m not familiar with the Yi cameras, I haven’t read that newest post, I’ll have to look into it. But, 12 Security is credited with disclosing the 2nd Wyze security breach in December 2019 (the 1st one not even a full calendar year before).
Wyze reluctantly admitted the breach days later, but went into damage control mode, claiming the DB was only exposed for part of the month of December. 12 Security says otherwise, that it was exposed for the majority of the calendar year, and many parties across the globe accessed it according to logs.

Neat, where did you order yours from? I've actually been looking for a sensor without a Bayer filter on it to use with a spectrometer, and this looks like the sort of thing that might be able to be used for that.
I'm not sure exactly what you are looking for, but there are a lot of machine vision cameras available that do not have Bayer filters and are grey scale only. https://www.baslerweb.com/en/products/cameras/ https://www.alliedvision.com/en/digital-industrial-camera-so... These cameras most likely DO HAVE a NIR (near IR) filter on the sensors. You would need to check on specific models. Basler provides some documentatio…
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…
