My friend and I hacked on something like this for a while, and eventually got something pretty accurate for measuring heart rate. Shipped on iOS as [0].

It did indeed require a lot of additional tweaks and benchmarking. Honestly don't think any part of our original algorithm or the tricks in the paper made it into the final version. Just doing a Fourier type thing works rarely (~20%), but the principle does work; you can get it working ~90% of the time. That said, I'd be surprised irregular heartbeat were doable in a short recording period. But I'd love to be surprised!

Nice work! The other day I was doing a SVG renderer for Shiki[0] (a code syntax highlighter), but found no easy way to measure font width/height (SVG needs absolute positioning) in Node.js. The only library that does that records fonts' metadata in the package source[1].

I ended up using puppeteer[2]. Would love to switch to `skia-canvas`, however `ctx.measureFont` doesn't seem to work correctly yet. Measuring cap `M` produces positive `actualBoundingBoxDescent`, although `M` should sit comfortably on top of baseline.

That is very cool, my dude. Someone else also built an AI writing assistant like this that I tried. It was really quite good.
Someone is spamming it from a lot of different IPs.
Unfortunately, given the times, I am supposing your question is asked in bad faith. But if "society itself viewed her as black" and then society itself found out that she was systematically lying about her childhood[1] and past experiences of discrimination[2], then society can certainly change its mind.

The real thing about race being a social construct is better expressed by Dubois: "the black man is a person who must ride Jim Crow in Georgia." That is, you can't discuss race without understanding that it's nothing more than a psuedoscience designed to enforce a hereditary and geopolitical caste system - discussing it taxonomically is a sucker's game.

So while Krug might have been able to successfully lie about being black (while also styling her hair/makeup to make the ancestry more plausible), that doesn't mean very much when she actually spent her life at the front of the bus.

EDIT: On race being "oppression first, ancestry later," see also former NAACP leader Walter Francis White, whose recent ancestors were mostly European but whose parents were both "clearly" black. White himself was blonde and had blue eyes, and he often went undercover as a white man. From Wikipedia[3, racist slur censored for HN friendliness]:

> Granted press credentials from the Chicago Daily News, White gained an interview with Arkansas Governor Charles Hillman Brough, who would not have met with him as the NAACP representative. Brough gave White a letter of recommendation to help him meet people and his autographed photograph.

> Learning that his identity was discovered, White was in Phillips County briefly before taking the first train back to Little Rock. The conductor told him that he was leaving "just when the fun is going to start" because they had found out that there was a "damned yellow nr down here passing for white and the boys are going to get him." Asked what they would do to him, the conductor told White, "When they get through with him he won't pass for white no more!" "High yellow" was a term used at the time to refer to black people of mixed-racial descent and visible European features.

Reminds me of reading an article talking about how Walmart used to lock people in who worked the night shift like stocking shelfs. Seems like Walmart was doing this in the early 2000s, there's an article from 2004 in the New York Times. Didn't know that there was a similar thing at Best Buy, wonder what year that was.

> How is something harmful if the effects are below a measurable threshold?

Your parent didn't say below a measurable threshold, they used a much weaker "you don't notice." Lead has been shown in countless studies to be harmful, and a lot of its effects are subtle like behavior and learning problems, hyperactivity, lower intelligence, men's fertility, fetal health, cardiovascular problems, kidney function... so you might not notice low grade lead poisoning but it can still be slowly wrecking your body.
> What would be a good line to draw?

Parking is a convenience, a benefit as such. Your responsibility is to arrive at the entrance, ready for work on time (or clock in). When someone from the company prohibits you from entry to clock in or leave on time, that is on the company.

Another aligned argument here, could be that the closet food restaurant is 20 minutes away and you have 60 minutes for lunch. It is not the companies responsibility to make sure you make it there and back in 60 minutes, you account for traffic, ordering time, eating time etc. But if the company stops you at the door with a security guard for 10 minutes, before you can go get your lunch, and when you enter back from lunch then it's their problem.

Flattening is a battle between gravity and a material's binding energy. The Moon's mass permits steeper slopes with similar material. (There are still limits, of course.)

I agree with this, we should allow our cats to be outside. However, I do not think we should allow domestic cats to roam wherever they please. We should let them roam in a somewhat controlled manner.

Additionally, feral cats are awful for native bird and small mammal populations. Your cat will probably hunt and eat small mammals and birds if you let it roam freely.

This isn’t true: because the secret never leaves your client machine, mitm attacks can’t be trivially leveraged to access other systems you have access to.
for the last month (v6.6.0 and v6.7.0) libvirt has been released with a new key 453B65310595562855471199CA68BE8010084C9C (first seen:2020-07-20).
It hasn't been signed or verified by any other source in libvirt / redhat yet.
https://www.redhat.com/archives/libvirt-announce/2020-July/m...

That is preventing downstream distros, like arch, from admitting these new releases into their package repos.

Critical infrastructure, indeed.
I think the key is, you can't tell if the system's been compromised by looking at it. And not even by taking it apart and examining it, bit by bit. Not without an electron microscope. And unlike with banking, you can't tell by the results either.

We need a clear way to communicate why it's so dangerous that computer illiterate people will understand, and that's as clear as I can put it.
Theft is a major issue and all anti-theft measures will result in increased cost. One possible option is for the battery manufacturers to make the stolen batteries useless by short circuiting them or something like that. So there is total deterrence against theft.

It’s fun to see the rhetorical positions nowadays: pick an argument that doesn’t require evidence and can’t be disproved. You’re always right!

It’s also a wet dream for people with anxiety and hypochondria - say the side effects are a complete wildcard and people assume the worst case scenario.
Cats do kill an insane number of birds. We've found that attaching a large, colourful collar with reflective bits helps immensely on our cat. Birds are highly sensitive to colours, and our observation is that the cat simply isn't able to catch any birds anymore. They see him coming far too early.

As for the other points, I suspect you're overestimating the dangers, but that's not my call. I personally think no animal should be kept imprisoned in a home, though; I don't want to give any animal less freedom of movement than I have. Imprisoned pets even more depressing to me than zoos.

I think a big step forward is for folks to pin versions of things. NPM and pip and many other systems let software depend on a semantic versioning of their dependencies which makes it impossible to know what will be installed. If you at least know what is going to be installed and the URL is known then you can rely on a third party notary to tell you the expected contents...

Which is what we are building with Asset Transparency to provide a public transparency log backed database of URL content digests.

We have started to build tools for integrating into release pipelines too:

The pay outside the hourly rate for a given employee should be total employee commute time (factoring in extra minutes for employee parking lot, etc) minus total commute time for a non employee from the same starting point (they can park wherever, etc), plus any time the employee is delayed before/after clocking in/out (waiting in line to clock in, security checks, etc).

I have nothing against TK or Racket. I haven’t used these two in particular, but I used equivalents like Windows Forms or wxWidgets, and I was happy with both. However, they only work when you don’t have high bar for visual quality, are happy with stock OS-provided controls with minimal customizations, and don’t have too much GUI in general.

GP mentioned styling and visual debugger.

Styling is needed for projects where you have a professionally-made GUI design on input (i.e. Photoshop or Illustrator or XD, or much less often non-Adobe equivalents), and want to make GUI close to that design. Such projects often include custom UX in addition to custom GUI, like animated transitions or decent touch screen integration for custom controls.

Similarly, visual debuggers are only needed when you have very complex GUI, and/or non-trivial UX code.

Other typical requirements for high-quality GUI are internationalization (Unicode all the way down including these surrogate pairs and ideally colored fonts, support for right-to-left languages), and good DPI scaling (this requires vector graphics for assets instead of bitmaps).

I don’t like Electron nor JavaScript, but I have to admit they are often the best tool for the job.

QT is close, but requires C++ with all the unsafe shenanigans, and depending on the project the license can be expensive.
One of my friends has a startup where individuals can sell computer time to the highest bidder. I've told him that I didn't think it was a good idea, but this library could change that. I wonder what the performance overhead is like.

Live in NYC. I know of a few people who have sadly died. No direct friends or relatives, but heard of relatives of coworkers who passed. Brother in law got it and was very sick for 4+ weeks and had to isolate.

Mar/Apr was a very scary time to be in NYC, it felt like you could catch it from just opening your window or touching the wrong elevator button. Now it feels less scary and less "real" here—even though I know it's dangerous to let your guard down. I am glad to see most people wearing masks diligently. Also happy to see people come up with ways to still patronize restaurants (they have all built makeshift outdoor dining areas).

I am shocked at how many people I overhear touting conspiracy theories about this or that [country/rich person/religious group] creating the virus, or that it will magically disappear after the US elections in Nov.

I don't think we'll get anywhere close to normalcy until we have a proven, safe vaccine being distributed widely. But I hope we've seen the worst as far as peaks, outbreaks and deaths.
JSON is a bad configuration format simply for the fact that it doesn't support comments. Some parsers do but most don't. XML for all its verbosity and complexity at least has comments where I can quickly try out configuration changes without needing to save the old configuration somewhere else.

Hell, even INI files had support for comments and were just as expressional as JSON. I wonder why we regressed in that regard. Was it just because of the success of JavaScript and readily available JSON parsers? Because I'd argue that an INI parser is just as easy to write.
