I've recently used na RPi4 with a ArduCam OV5647 camera and a LS-40180 Fish Eye CS mount to make a home security cam as a fun project. Works nice and has a 194 horizontal / 142 vertical FOV.

I wonder if that setup would work for something like this? Does anybody have experience using cheap RPi-like equipment for things like these? Am I correct in assuming that this wouldn't work because of the low sensitivity of the sensor in the cam (I know next to nothing about photography)?
Ask HN: Help scaling a site for Covid workers
I was approached by people who have deployed a site that connects front line Covid health care workers with free local therapists. It's being used in the SF Bay Area with talks to roll out to the entire state and beyond.
I'm not affiliated at all with the effort but was approached to help push it forward in any way I might be able to. It was built quickly using Google Sites. The site displays therapist information, scheduling information. It collects no PII that I'm aware of.
I think this is a great service but it's a bit out of my domain so I'm looking for help with helping them. Some questions I have is should they move off Google Sites before trying to expand use or can they stay with Google Sites for now? What are some ways I might pull together other resources to help with this? What can I do to help them move this forward?
Thanks all

> Does that imply that steroids suppress the immune system in some way?

Yes. This is the reason why they're used in the first place.

Yes, but an entire year's worth of asthma inhaler is like one dose of oral prednisone, so the impact is quite low and you should not stop using your inhaler.

Yes.

Yes.

The data grids in PowerApps are woefully inadequate though... and people have been asking Microsoft to improve them on their forums for a while to no avail.
Ah gotcha. Hence I preceeded it with "I think..." Which part is not the case?
And heck, things like forward error correction and 5/4 encoding are giving up on getting anywhere near the Shannon limit and just trying to boost the average and worst case behavior high enough that people don’t throw their equipment away. If you do both and tcp/ip over the top you’re creeping up on 1/3 of the channel theoretical bandwidth just to make sure something, anything, makes it through.
This feels to me, like the next best vector to compromise users.

It's fascinating, reading how they figured all this out. Correlating data about magnetic field flipping, uranium decay, a dozen little things coming together to give an answer. I'm not sure what kind of implications this find has and the comments from from Mr. Spoor seem to be taking a cautious approach but just reading about the work of scientists is always exciting.

If all the data pans out, what kind of implications would it have? Just showing that different kinds of humans coexisted and cohabited? Or is it more about the migratory patterns of these different humans?

“We Are Treating the Wrong Disease and Doing More Wrong Than Good”
Not a lawyer, but to any fellow H1B's who are concerned about being laid off, and facing the near-impossible task of leaving the US on short notice during a worldwide lockdown: a 2017 law provides a 60-day grace period for "those whose employment ceases prior to the end of the petition validity period". Ie. if there is time left on your I-94, you should have 60-day grace period where you will remain in-status while you look for another job.

Here is the full document: https://www.govinfo.gov/content/pkg/FR-2016-11-18/pdf/2016-2... (search for "60-day nonimmigrant").

Note that during these 60-days you can then file for a change of status, and then you will still remain in-status while that request is pending (the change you file must be "non-frivolous" though!).

If you follow this route and try to change status, USCIS has the right to revoke the grace period retroactively (in cases of abuse, for example). Documentation that you were actively seeking new employment should help avoid this.

Anyway, concerned people should certainly speak to an immigration attorney (again, I am not a lawyer), but it is comforting to know that most likely we have 60 days to get our affairs in order...
Window Maker 0.95.9 Released
Exactly, that's the state of the experiment. There's just so many things that could have gone wrong without us noticing. Even though we trust the instrument is working, we don't know if the material under study is exactly as we expect.
As a matter of economics, that sentence is nonsense. Tax incidence is determined by elasticity of supply and demand, and has nothing to do with the logistics of which person gives money to which other person. This is the perspective that matters; you can easily observe for yourself that two taxes on gross revenue will have exactly the same effects if the only difference between them is that one is called "sales tax" and one is called "revenue tax".

As a matter of logistics, your claim isn't nonsense. But it is quite obviously false. The consumer gives money to the merchant. The merchant gives money to the government.

As a matter of legislation, it is, once again, plainly false. Here's the beginning of the California law imposing the state sales tax ( https://www.cdtfa.ca.gov/lawguides/vol1/sutl/6051.html ):

> For the privilege of selling tangible personal property at retail a tax is hereby imposed upon all retailers at the rate of 2½ percent of the gross receipts of any retailer

(emphasis mine)

And the law _must_ be stated that way, because if a vendor is selling something for $100 + sales tax, the customer pays $100 ("no tax"), and the vendor accepts it, the customer hasn't violated the law. The vendor is allowed to charge whatever price he wants. It's the vendor's responsibility to pay tax on the $100 of gross receipts he just received.

There is no framework in which "sales tax is paid by the consumer" is true. What were you thinking?

Right, now look at where "from" and "to" are in my sentence.

During and for years after WWII, the US was a major net exporter of oil, which is why I felt the need to specify the approximate start (some time in the 1950s or early 1960s) of the US's dependence on imported oil.

Yes, let's move away from the standard syntax used to specify generics, which is used in virtually every widely-used programming language of the past 15-20 years I can think of, and instead redefine the most common syntax used for array indexing (oh, and make array indexing look like a function call).

This fixating on relatively inconsequential issues, while totally missing the forest for the trees, is a dangerous attribute I've found in a small subset of programmers.
The town I grew up in would flood regularly (pro-tip: don't build your on town on marshy ground where two rivers converge).

Having one or more floods a year was a fact of life and the local store owners would design their stores to deal with that. The best example was a newsagent (remember those?) that had their magazine/greeting card shelves on jacks. Fully loaded racks of magazines would be jacked up 6ft or more, the water would come through the store, they'd hose out the tiled floor, and be back up and running within two or three days.

And then the town built a levee that would deal with everything except 1-in-100 year floods. So the town didn't flood for 10 years or more. People became complacent, and new store owners had no experience (nor plans) for how to empty their stores should the levee be overtopped.

The first time the levee was overtopped, the old timer shop keepers started to prepare their stores for the flood waters (emptying stock, removing electronics, etc.). A surprising number of newer shops literally did nothing, even when the government was telling people the levee wasn't going to prevent a flood. And, predictably enough, a lot of the newer stores literally never came back.

Moral of the story (if there is one)? It can be hard to prepare for bad times if you've only ever known the good times.
I think that this is the exact opposite of the point of government programs. We try to build these programs in such a way that they avoid the tyranny of the majority. Especially when you consider that those who need accessible interfaces are more likely to need government assistance in other parts of their lives.

Rye flour is vastly under-appreciated in my opinion. Love that stuff.

For a lot of things you can't really get away with fully replacing wheat flour, but you can usually do half / half with good results.

I haven't made sourdough for a few years, but I think I was either doing 1 : 1 : 1 (white, wheat, rye) or 2 : 1 : 1.

Also, the easiest way to create a sourdough culture is literally just mix rye flour and water in roughly equal parts. Cover with a cloth to keep bugs out, and then dump out (our use) half each day and add in more flour and water to get back up to the original level.

It's basically the most idiot-proof process I can think of.

The main reason I keep getting out of the habit is that you need to monitor the thing basically daily. Otherwise you can put it in the fridge and take a bit less care of it, but then you need to build it back up for a few days before you can use it.

I've always wondered if I'm just being too cautious about the starter though. I know that people have said they thrive on neglect.

Actually, before buying my Bose headphones I seriously looked at the Sony's. I even googled for a way to disable the touch control on them. But the only thing I found was a video on YouTube for the previous model, which showed how to disassemble the headphones and disconnect a wire to achieve this.

But good for Sony for giving that choice to the user via a firmware update.

IMO Paul Tarau has some good stuff in this area, e.g.: "On a uniform representation of combinators, arithmetic, lambda terms and types", Paul Tarau https://dl.acm.org/doi/10.1145/2790449.2790526

Abstract:

> A uniform representation, as binary trees with empty leaves, is given to expressions built with Rosser's X-combinator, natural numbers, lambda terms and simple types. Type inference, normalization of combinator expressions and lambda terms in de Bruijn notation, ranking/unranking algorithms and tree-based natural numbers are described as a literate Prolog program.

> With sound unification and compact expression of combinatorial generation algorithms, logic programming is shown to conveniently host a declarative playground where interesting properties and behaviors emerge from the interaction of heterogenous but deeply connected computational objects.
But if you are a PE and you're constantly buying companies for a 100 million by borrowing 80 million then driving the company into bankruptcy. How are the lenders getting paid their 80 million and how are you getting back your 20 million?

And if the lender is getting screwed out of 80 million dollars why do they keep lending to private equity?

It's not his main argument but it's an assumption that has to be true for his main argument to be true.
If you know of a lower bound that's higher than mine, based on as/more reliable data, you should mention/link to it. People are doubting the Lancet paper based on data source (I don't have a strong opinion on that), so this bound based on a different source of evidence should provide additional information for policymaking.

Your lower bound based on the population of earth is clearly not it.

> The "why are people surprised" line is a huge red flag for me that a person is not arguing in good faith. Accusing people of being "surprised" as an implication of naivete seems to be a very common tool of redirection when people are defending something perceived by others to be immoral or otherwise harmful.

This is a bizarrely uncharitable take. Posting an article implies some form of novelty, which is why we don't see articles posted saying things like "if you don't water your plants, they die" or "companies with large valuations tend to have high profits or revenue".

The parent comment isn't claiming that the lack of novelty makes an otherwise-bad thing acceptable; he's saying that any reasonable model of the current state of corporate taxation should already have assumed something like this.

He _separately_ makes the claim that legally minimizing one's tax burden isn't immoral; this is a claim that you can disagree with, but pretending that he's dismissing this entirely due to its lack of novelty is a bizarre non sequitur.

Tech exists in a new world now. The tech itself and it's surrounding landscape is starting to get boring.

- It's dominated by fewer companies that only seem to grow larger and larger. These companies haven't changed for a long time. Boring.

- Everyone decided X86 is going to be the main platform for everything that's not a smartphone or embedded device. Hardware has become boring and locked into this.

- Anything embedded that can have 32MB or more of RAM is an ARM-based Linux system. I think there's still a few MIPS holdouts. Embedded has become boring until RISC-V gets critical mass.

- Anything new mobile is either Samsung or iPhone. ARM bricks with touchscreens, battery, and a bunch of sensors. Fundamentally not different than the 2000's, just faster, more efficient, etc. Smartphones and mobile have become boring.

- Most people are poorer now than they were in the boom 90's when all this started. So everything becomes a spy platform to deliver ads. This is so common it's boring now.

- The smartphone and streaming have replaced the TV for everyone except boomers. Video streaming as a technology stopped being interesting a long time ago.

- Facebook and apps have replaced the news for most people. The rest have 24/7 cable news broadcasts. Facebook has been around a long time. It's not a mystery how Facebook works. It's boring.

So, political, social questions are coming more to the forefront.
> How are you going to disagree with me having never touched the product?

You claimed that volume and skip controls weren't important ("the important controls are buttons ... capacitive interface is for ... vol up/down ..." implies volume controls aren't important). That is what I disagreed with. I don't need to have used a particular pair of headphones to know that volume and skip are important controls for me. Same way I don't need to have used a particular keyboard to know I value having an "e" key.
Your camera is your limiting factor here - at 5MP, and ¼”, you have some pretty small pixels. The dark current etc.
is unspecified in the spec sheet. The lens is small. Together, that means low photons per pixel, and noise becomes dominant.

You would probably be able to image something, but you’d want a bigger sensor and lens ideally.

That said, you can still do plenty if you’re willing to set the thing up on an electronic equatorial mount (very cheap and cheerful would do for wide angle) and take many long exposures, and stack them - but the moment you try it with better gear you’ll be wishing you hadn’t bothered!

But then that’s a physical move. Plenty of companies have their executives/leadership in a location that is different from the taxable entity. If all the headquarters and executives physically resided in Caiman islands or Ireland or even Delaware, it would be different.
