> It therefore requires the measurement of light transmission or reflection from a body segment such as a finger at two different wavelengths (usually in the red and infra-red).

> The Samsung Galaxy series of phones had a red light emitting diode (LED) built into the phone in addition to the flash light and camera. There were no details released by the company of how its app used the LED to estimate oxygen saturation, but it appears from publicity material on YouTube that it worked via a single-wavelength measurement (albeit with a monochromatic light source, the LED) and therefore that oxygen saturation could not be accurately derived from it.
I think you have a misunderstanding of what mathematics is. Mathematics is the field that is as removed from reality as possible.
So let's say that so far you stood apart, are or not at risk population (age, previous conditions, whatever) or just live with someone in that group. Now the shutdown gets over, you have to go to work or else get fired, and odds that you meet someone with the disease will be still high (the 20% in the Bronx is an indicator).

I don't see how this could backfire.
Cockpit doors were pretty straightforward and appeared almost immediately. There's a pretty good chance we will never have an effective COVID-19 vaccine. No knowledgeable scientist thinks it's a sure thing, nor that it will be widely available anytime soon.

Airplanes are uniquely awful in that people are packed closely together and the air is almost entirely recirculated. Nothing else even comes close.

That’s what I meant, yes. Interesting approach and impressive.
That's really cool. I haven't seen photogrammetry offerings that much in the space you are targeting.

How good is the spatial resolution? Do you see your gear competing with Lidar pointcloud scanners any time soon?
I have just downloaded it too and witnessed this issue, the text looks weird, like a little bit blurry, it would be perfect if it looked like on Sublime Text 3 or on this image https://i.ibb.co/qYCpx3x/1588859182372.gif
They aren't equally difficult problems. From a thermodynamic perspective, all processes in your environment deteriorate into either waste heat, or is moved outside your environment with work.Low-cost heating is easily available, whereas cooling can occur by moving heat to another location.

So for heating, you can just max out on insulation, decrease your surface area to volume ratio, and the waste heat from interior equipment will be more then enough to provide 'free' heating.

If you outdoor temperature is high (so natural ventilation doesn't do anything), there really isn't much we can do other than try and find higher and higher efficiency heat pumps to cycle out the heat, but even then you're just dumping the heat outside which creates its own issues. We can reflect/control short/long-wave radiation, but the sensible heat from the environment is a problem. Not an impossible problem, but requires more sophistication to resolve.
Looks like a really slick app, can't wait to walk around and use it.

It is a little funny to see that some of the quests are on map features that I have recently added. I suppose I will both fix those things and learn what I can do better when I am mapping in the future.
The picture of Craigslist being unbundled shown in the article is really good. Is there a similar pictorial “map” of the space zapier covers?
NYC's 20% infection rate of 20% was reported on April 23rd.

There is no reason to think the virus is more deadly outside of NYC. To lockdown until a possible vaccine is to kill additional thousands beyond those who will die from COVID-19.
Personally, I'm thinking of its comparison to Geany. A wonderful editor but I have a feeling the first difference is it's going to seem real bloated. Time to see.

https://youtu.be/z0-86M6DOqM I worked with Palmer luckey in 2009, he credits me for the idea of the rift in the Blake Harris book, history of the future. Chapter 33, William (bill) Wallace. I got scared when I found out he lied about making the rift open source as he promised for years. The day the Kickstarter went live, he removed all references to open source. He also had accepted 17 million from people like Stanford rapist Joe Lonsdale before the Kickstarter, causing Kickstarter to be sued and forcing them to change several official policies. I remember telling Palmer in 2010 about an old ad that Activision used to run about the infocom games, a picture of a brain that said no graphics processor could ever match human imagination. I just watched the get lamp documentary and found the Crawford and Pinsky interviews deeply spiritual. Have you ever watched a movie called world on a wire? It's an old German film about the simulation hypothesis.

This isn't true.
Sites like github often "optimize" images to lower bandwidth costs. Basically any platform you share images on that is at scale will probably re-compress images. For PNG they often reencode the image in a lossy way.
We don’t know, obviously, but immunity to some other coronaviruses only lasts a few years.

The question about why some viral infections confer lifelong immunity while others don’t is still an open question, I believe.
Show HN: Fully unshare and transfer ownership of Google Drive folders/files
The scale issue is a problem with any software like this unfortunately, it makes doing this type of processing in chunks very difficult as you are getting different scale outputs and nothing really relating the chunks together. OpenSFM does some neat stuff where they use location data and just search for matches between images near that location.
Sure, but if someone says they want not-heroin, but spends money on heroin, that doesn't mean they want heroin, except in the most asininely reductive misrepresentation of their preferences.

Maybe most people don't care about, say, the existence of servers that will put their desires above those of the game company (which is one of the things self-hosted software practically provides; no one disputes that running the server on your PC just because is a niche scenario), but the fact that they fail to effectively strategise their spending toward that goal is not evidence in favor of that conclusion, because it's much more easily explained by the known fact that people (note I didn't say "most") are short-sighted, impulsive, technologically-illiterate (okay, that one's most) hypocrites in most of their decision making.
Ask HN: What should I do with my expiring AWS credits?
I have a pretty sizeable amount of AWS credits that are expiring in a couple months ($15k).

Any ideas on how to make use of them? The unfortunate thing is it'll probably mean we leave AWS, as it's not a perfect fit for us (unrelated). It seems a bit silly to just let them "expire" though.

Would love any thoughts on how to make use of them before they expire.
Yeah, GPU helps a lot. I did not mention it as I personally find the idea of a desktop machine without a good GPU... crippled :)

So far COVID-19 has killed 0.25% of NYC, with that number continuing to rise. The idea that fear is more dangerous than that is facile.

+1. You can easily turn 10 hours of connecting the dots into 2 hours with the right materials.

Though in my experience, the courses on Udemy/Udacity and the like have been disappointing. I always get the feeling that they're trying to fill up time, and they tend to move really slowly.

I've had more luck with books being very useful.

Haven't there been commentary about finance struggling "more" to find talent more in the decade after '08/ Occupy Wall Street?
Now a lot of that talent has gone towards ad-tech probably, which now is itself getting the negative press.

What's special about their engineering?

You can easily point to ford and Toyota's major innovations that changed not only the car industry, but manufacturing on the whole.

The Prius also stands out as the big success on moving drivers off of fossil fuels. What's Tesla got?

At a surface view, I'd say their engineering is worse than their competitors. Poorly engineered products and manufacturing processes make for slow production -- a problem that Tesla is pretty famous for o think?

My understanding is that they design overly complex parts and use overly complex mechanisms to build their cars.
I have mixed feelings about Udemy. On one hand, it's a large platform with lots of interested customers. On the other, courses are often heavily discounted and priced very low. 50+ hours of content for $20? You have to treat your audience like they're both smart and busy. I don't have time for that. I'd rather pay $100 for 5 hours of good content.

Doom has had an immediate huge impact in its time ; even before the source code got released the game had a hacker-friendly wibe to it. For instance DEU (the first editor I used) was released in 1994 (https://doom.fandom.com/wiki/Doom_Editing_Utilities). The 'unofficial specs', still invaluable today if you want to hack Doom, were released in 1994: http://www.gamers.org/dhs/helpdocs/dmsp1666.html

Magazines would bundle floppies (and then CDs) full of levels, with new textures and recorded games. Total conversions were made. Tools appeared to directly manipulate the executable and achieve various effects. As far as I remember no other game before had clustered such a large and active community around it? (which is not to say that no other great and amazing games existed before, so many gems lie in the past!)

And then there was the networked play. I spent an afternoon with a friend soldering a cable to play 'null-modem', and we got it working around ~6pm. At 5am the next day we were still playing, me on a luxurious 486 DX2-66, my friend in a tiny window on a 386 DX-33Mhz, both with red eyes. This was an experience like quite no other at the time.

The gameplay was simplistic but huge fun. The immersion was intense. The tech was stellar. But I am obviously biased by nostalgia ;)
I don’t think that’s an issue here, as PeerTube is a software package, not a hosting service (that I know of). I can use it to host Creative Commons videos, and you can use it to serve box office movies, but in either case PeerTube itself has no say in how you or I are using it.
I'm lost on exactly what you are trying to say here. Something that can be radix sorted can likely be condensed at least partially to an integer.
TypeScript: Unions
Thank you for the kind words. As I’m writing it I just keep thinking “How would I want to be taught this?” As another parallel rule of thumb I pretend that I’m writing to someone who is smarter than I’ll ever be but,

1. Doesn’t know anything about this particular subject yet.

2. Is probably very tired from whatever it is they’ve been doing. (Day job, raising kids, just general anxiety keeping them awake all night, etc.)

3. Might be drunk.

So I try to be plain in my language choices, calming when facing something with an aura of complexity (eg. “this thing that you heard is complex is really just a fancy name for these two simple elements combined”), consistent, and to present actual examples instead of everything just being an impenetrable brick of text.

(And then occasionally I break all my rules by throwing in hyperlinks to random tangents / hiding Missy Elliott lyrics in the code / whatevs.)

I posted about this the other day in the Finnish thread - of course they are, there's probably a 300% salary difference between a banker with 6 yoe and a social welfare worker with 12+ yoe. You don't have fields attracting people for purely financial incentives when the salary difference between these two is more like 10-20% for a seasoned professional. It's an entire systematic issue which has compounding effects, but when you mix in global instability, food security, etc. would you rather play ball here or expatriate and take a risk with the educational and career opportunities your children have somewhere else.

So, obviously, "native" is a spectrum. On OS X, Cocoa > QT > Java > Wine > Docker + X11 forwarding.

But one thing I think is being missed here is that Lua, Python, and other scripting languages are just a lot more resource efficient than electron, in terms of runtime size, memory usage, cpu usage, etc. A very highly optimized Electron app like VS Code might outperform a more run-of-the-mill Lua app, but that's an outlier.
This page keeps crashing on my phone. I can get down to the toilette flushing.

This is going straight into the toolkit. The main thing that keeps me from doing more inline python is all of the printing boilerplate.

Well, two things, the second thing being performance.

How's the startup time? I find it hard to get python utils under a few hundred ms just to spin up.
I think the issue is that techy/engineer-types are big fans of elegance. It's undeniable that services like Zapier are elegant in the sense that they generalize pretty well, they can "do it all" and, in all honesty, they're not too hard to figure out. With that said, there's no true value in elegance. And while generalizing is definitely a good idea for a mathematical proof, it might be a bad idea for a product.

I have to admit that a lot of times (especially when building side-projects/toy startups), I second guess myself when it comes to these kinds of product decisions -- "Is this product too simple? Too bare-bones; too much of a one-trick-pony? Would anyone pay for this?"
Something similar is Revery, written in ReasonML (OCaml) [0].

While your local authorities may have voiced such a recommendation for people to follow, as far as I know, no country which has mandated mask usage, is requiring specific behavior around the donning and doffing of that mask. (Please point to specific legislation if this really is the case where you are.) If there is no requirement and enforcement mechanism around a certain behaviour, then IMHO it is excessive for any of us here to complain that the general public is not observing that behaviour.

We can only expect the general public to observe any restrictions to the least possible degree; only if there is a hard rule that is being enforced will society overall heed it. Public-health authorities generally know this, and so if they are not pushing for certain behavior to be actively enforced, then that behavior likely matters less to curve-flattening efforts than you might assume.
Unfortunately no... I should have made one!

Essentially Zapier would technically cover all integrations. So any sort of data transformation from one app to another.

SDL has hinting because it uses freetype. But this program doesn't use that. It uses stb_truetype which does not support hinting.
> virtual DOM implies DOM existence

No, it doesn't. I addressed this in the comment above. React's virtual DOM has been used to render:

- Plain HTML (e.g. server-side rendering)
- Native UI framework objects (e.g. React Native)
- Text-based interfaces (e.g. Ink)
- Smart TV devices (e.g. Netflix's Gibbon)
- Browser `<canvas>` elements
- Markdown formatted text

And a whole bunch of other targets.

> DOM based systems use so called retained mode rendering. But this one uses something that can be classified as immediate mode rendering.

This seems orthogonal to the question? I'm not trying to be difficult, I sincerely don't understand why this would mean the two are "not even close".
This made me nostalgic for a utility I wrote back in 2005 called `pyline`:

http://code.activestate.com/recipes/437932-pyline-a-grep-lik...

I'm sure I wasn't the first to scratch that particular itch. It always seemed odd, back then, that Python didn't have better support for the Perl one-liner style of programming.

Card counting is possible but extremely sensitive to the precise rules of the game being played.

The principle is that you bet (more) when the cards remaining in the deck are favourable to you. Even if you can identify when that happens, precisely or heuristically, it's then also important to consider what percentage of your bank you can bet to best avoid bankruptcy.

If you've considered all of this carefully enough, your method will likely no longer work when the casino modifies the rules in any way - most crudely by increasing their take to cover any variance in bet value.

Edward O Thorp explains the mathematics of card counting extremely clearly and readably.

Well at least your thoughts seem very distorted because you seem to claim that using the tool of language is useless and no one should do it, and then still keep using it and even try to defend using it.

"Language itself is a distortion of your thoughts" is just one of those truths, one of the first things any growing human being sees when they start on a journey of spiritual growth. The point of it is not to stop using or stop trusting the language, stop communicating. The point is to see how it works and how it relates to the rest of the self, so that it can fulfill its great potential as a tool for spiritual growth and learning.

There's the obvious time savings, but to me there's additional value. Docs tend not to be learning focused, and you'll end up reading a lot that doesn't matter for your desired result. We get paid for business objectives, not framework knowledge. Additionally, there's so much docs don't cover, in terms of standard opinions and best practices (eg, "Where the f* should I put this file?!") that experienced practitioners can guide you.
Why save the start and end? Why not just save the barrier between each line?
To require non-essential workers to go back to work right now is far more fascist than to require people to stay in place to protect their health, but Elon sees it the other way. He wants people to weigh whether their lives and their loved ones lives are worth being able to afford living in a society that won't give them a bailout because of scabs like Elon, only focusing on stopping the economic bleeding while humans are hurting in more profound ways.

We don't live in some utopic society where Elon gets a special authority to do whatever floats his enormous personal debt. Compromise is required. That means selling some TSLA shares to pay that debt so that you don't become a scum-sucking demon.
