That's sound. Very lossy sound, presumably at a very low frequency, but sound nonetheless. There's a physical medium, and a signal is being passed through it via tennis ball pressure. If you had a sufficiently dense field of tennis balls, you could visually observe the wave moving across it as the field compressed (in the direction the signal is traveling) and then uncompressed, cyclically.

A good trick to telling the difference is thinking about the direction of the frequency. Frequency is a back and forth movement. If it's going back and forth in the direction the overall signal is moving (like a tennis ball going faster towards the destination and then more slowly or backwards, or like the wall at the source of the signal vibrating towards the other wall), that's a physical wave. If the back and forth movement is happening in an entirely different plane, that's like an electromagnetic wave.
I was in stitches watching that. So good. Never knew about it either! That would have gone so viral if social media was a thing back then. Absolutely classic.
"But, in a country like the US, the high risk population is much, much larger than the nursing home population. Age or health conditions means that probably at least 100 million people in the country would be high risk"

FWIW, 65% of the 9373 COVID19 deaths in Massachusetts occurred in Long Term Care homes [0]. This is a terrible thing that could have been prevented (or at least mitigated) and do I believe the Commonwealth has failed here. However it does seem to indicate that LTC home occupants are generally more at risk than people not in a LTC home (which seems to make some sense, if you're in a LTC home, it's probably for a reason -- e.g. significant health issues/frailty). We can do better.

This is what happens when your language allows statements and you only want expressions! It’s okay to have conditions in code! It’s that they should always resolve to a value.
I became an awesome salesperson once I started selling something people wanted.

Prior to that it had felt hard - I thought it was hard because I wasn't an experienced salesperson.

It's got to be the same with demos - what you are demonstrating matters. If you're demonstrating something that people want, like, are interested in and understand then the demo will go one way. If you're trying to demo something they don't need/want or understand then it will go another way.

If you are demoing something people are ambivalent about for some reason then IMO you are better spending your time on making some other product rather than trying to craft the ultimate demo for the thing they are "whatever hohum" about.

It's the product/market fit thing. If you've got product market fit then the customers will pull it out of your hands.

The REALLY hard thing is of course making something people want, but I'd rather spend my time on that than being really good at selling something hohum.

I don't really agree with you being downvoted; I love LaTeX, I use it for basically any kind of mathey stuff that I need, but it is an objectively irritating language, especially for beginners.

That said, the fact is that for mathematical equation editing, for better or worse, TeX-based systems have a near-monopoly on high-quality typesetting; KaTeX giving us a fast, easy-to-use implementation of it is still a net good.

Ask HN: What is the best way to learn how to build your own hardware?
For the last few years, I have really had a strong urge to build a smart device. Basically, a mixture of a Google Home, with a light that can remotely change colours.

The thing is, I don't really know where to start when it comes to actually building a device that would be able to do this.

Does anyone have any recommendations on the best way for me to start this journey? Any books, YouTube videos or websites that might guide me on the right path?
This looks great! I made something similar for crypto back in the day, though it was much smaller.

Can I ask what tech stack you used?

That sounded sort of vacuous to me at first, but I think it’s a genuinely good point.

I think human nature or whatever you want to call it is always going to mean that some number of people don’t follow The Rules to some degree, and that achieving 100% perfect rule adherence should not necessarily be the one and only goal of society.
>Is not privacy a fundamental American principle? What the hell happened?

Eternal vigilance is the price of liberty and we have not been vigilant.
That's not entirely accurate. It's not uncommon to see "prevailing party pays legal fees" in American contracts.
Sorry, let me be clear, it's absolutely a good thing, and I exodized (if that's a word) quite some time ago. It doesn't seem to be happening fast enough, which I will attribute to a lack of a clear, decentralized but dead simple alternative.

Look at how quickly something like BitTorrent was adopted back in the day.... it's an esoteric and difficult to understand thing under the surface, until clients and sites came along that made it super simple.

Maybe Urbit will evolve into this, maybe Mastodon, we'll see.

I didn't claim that paywalled articles are not on topic as submissions, I claimed that short, dismisive, substance-free, non-contributing, non-constructive comments whining about paywalls when the article is not about paywalls, are not on topic as comments.

Had I read the FAQ more closely, I would have pointed directly at the entry "please don't post complaints about paywalls. Those are off topic." in defense of flagging and downvoting said comments.
How would an argument against Chrome this even hold up? Google has decoupled the technology from the distribution. The chromium browser is open source, any body can build on it and many companies have. The platform where chrome is pre-installed doesn't prevent the use of other browsers and underlying technologies unlike Apple. How does consumer preference make one a monopoly when moving away from chrome is not difficult at all as you have no lock-ins
> You skipped the part about how it was right. Current IFR estimates are on par with the flu:

For some reason, I assumed that once we got to hundreds of thousands of dead in the US, that people would move on from this.

Even the CDC puts the IFR around 0.65%. And, for example, you've got multiple boroughs in NYC with hundreds of deaths each that have exceeded a population fatality rate of 0.5%. You've got entire countries that have passed 0.1% population fatality rates. And, of course, none of these places have actually hit 100% of their population being infected.

> Moreover, Michael Ryan of the WHO estimates 750M infected globally, which would put the IFR at around 0.1%

This is only useful if you also estimate deaths, otherwise you are comparing confirmed deaths against estimated cases. Given the level of missed covid deaths, this only works to downplay the fatality rate.
That is because it is NOT written in JavaScript.

I have written JS since 1997 and kept up with ES6 and so on over the years. Used it in frontend until now.

The JavaScript-ecosystem just isn't very productive [1] for multiple reasons. The language is untyped. You have no multi-threading. It's hard to debug. You have to spend many brain-cycles on learning Browser-problems, which muddles your understanding of the language. The web-way of: we can fix it and everyone will reload the browser, leads to a "don't care" attitude.

For web/backend this is approachable, though still not good.

For build-systems this is terrible. Why? Because if a bug shows up in a build-system you stop a million developers from being productive. The bug won't get fixed right away, most will just work around it, use different plugins, copy/paste yet another webpack config etc.

Plus JavaScript tends makes people realized what FP is, and they all start putting functions in their functions and making everything modular and plugin-able. (See high-order-components in React). While this can be nice, it leads to even more confusing bugs.

Writing plugin-architectures is hard in any language. Writing it in JavaScript is a recipe for disaster.
Hence the modern JS-ecosystem.

Thanks! Rails for the webserver. Postgres and Elasticsearch on the backend!
Thank you. Maybe it's easier to recover the river from the optimisation case: we profile first, then optimise. This is because the only things that count are what actually eat wall clock time. Similarly, the only places in value chains that accumulate wealth are where there are actually consistent margins. And it doesn't matter if there are rocks in a riverbed (which could potentially make bottlenecks or waterfalls), if they're located in a pool between higher rocks, so the water level is higher than they are.

Does that make more sense?
Sony has their own software for using your mirrorless camera as a webcam, whether APS-C or Full-Frame. But the quality is inevitably lesser to an HDMI adapter. A version for MacOS is being developped, according to their website

It's called "Imaging Edge Webcam" : https://support.d-imaging.sony.co.jp/app/webcam/en/

I'm personally using an A7ii with a Tamron 28-75 for Canon EF, and it works much better resolution and quality wise with the HDMI, just because of the limitation to 1024x768 of the USB camera mode, which was really meant for tethering. Coupled with a 4$ phantom battery, it's awesome! I can get a clear image in the very low light conditions of my room at night, too. No need to turn the lights on, even :)
With governments consistently landing on the wrong side of good, no wonder people seek comfort in things like qanon.

You didn't put quotation marks around the second, and the first has no spaces, so this is not a fair comparison. "undefined is not a function" with the quotation marks has 449,000 results.
No need for a mirrorless camera, most DSLRs can do it, if they support clean HDMI out/external recording.

Have you ever used another browser and seen a "This site works better in Chrome, download now" on a Google property?

They do it even to other Chromium based browsers. They degrade the experience on Firefox, Safari, and Microsoft Edge, persistently nagging people to switch browsers.

That persistent nagging has an impact, especially for non-technical users who might only understand that Google, YouTube, Google Maps, or another Google property they trust is telling them that Chrome is better. Well, if Google is saying it, it must be true, right?

And that's not even mentioning the ways in which Google has degraded the experience in more tangible ways by turning off features for mobile browsers, fighting app compatibility on Windows Phone to the point of breaking Google Maps - literally just serving an inferior experience and using user agent detection to impair Windows Phone - or blocking the YouTube API on the device.

I just opened up google.com on Edge and this popped up in the top right corner:

"Switch to Chrome for Windows

Built for Windows. Hide annoying ads and protect against malware on the web."

I then went to maps.google.com:

"Google recommends using Chrome
Try a fast, secure browser with updates built in"

I then went to news.google.com:

"Google recommends using Chrome
Try a fast, secure browser with updates built in"

That was just a fresh first sign in experience, and as I understand it, these prompts recur - I still see them occasionally on my primary browser, Firefox!
> "Well, their existence as a trans person does, when you reject their own identity and replace it with one you have chosen instead."

The hole in this argument being that one can substitute anything else, no matter how outlandish, into that justification and it fits just as well. Try substituting "furry" in and ask yourself whether you are willing to add accommodations for people in fursuits. (And I'm sorry to pick on furries; the few I've met seem like nice people and are sincere in their identity.) If we wish to go for a more disturbing example, there is body integrity dysphoria: https://en.wikipedia.org/wiki/Body_integrity_dysphoria . These people are also sincere in their identities.

(And for the record, I'm a liberal and have no problem with trans people. But the above is just not a compelling argument.)

> The reason there is no huge Amazon.nl is the same reason there's no huge eBay.nl; there's already a large local competitor: Bol.com (and Marktplaats.nl).

eBay has owned marktplaats since 2004. I think they’re conceptually the same.

I’m also unsure if eBay’s modus operandi has ever been to acquire and transition local platforms to their eBay platform, which is probably for the better.
For sure. Massachusetts seems especially high as a percentage re nursing homes. I believe the national average is ~40%. So, absolutely, a priority should be to focus on nursing homes.

And that's also part of my point - nursing homes were known to be extremely high risk from the very beginning - remember that outbreak in Washington. Despite that early warning, we still, by and large, failed to protect these smaller, super high risk communities. If we can't even do that well, what chance do we have in protecting the much larger "high risk but not super high risk" populations?
What you have to tolerate in non-free societies can be far worse. It's just not called "crime". History is full of examples.
Don't forget that the people writing the grants are heavily influenced by what is required to obtain a grant. If the aim of writing a grant becomes to not be in the bottom 25%, than the average quality of grants will go down.

I think it has not been proven to be impossible to determine the difference between a top 5% and a top 10% grant, it has just been proven that the current system does not do that. In trainings for grant applications it is often mentioned that members of grant committees spend extremely little time per grant proposal, which I imagine is just sufficient to weed out the bottom 25% proposals (those that contain obvious flaws)
I gave this problem a stab a few years ago. I wrote an ascii-math derived language (but more powerful, and a little easier) called MathUp. I planed for it to be quick to write and easy to read (kind of like markdown for math). However it is not nearly as powerful as latex (and I don’t plan for it to be). Target are people that are writing quick math-notes (e.g. in class), or on forums where participants don’t necessarily know latex but might need to write a non-trivial equation or two.

On the very small boards you use chording to access different layers for symbols and numbers.

Like for me I hold down my right thumb key (which is also space if i were to just tap it) and that changes the layer allowing me type symbols like (){}[]<>.

In practice it's as if you were using shift to capitalize something and it becomes second nature very quickly.

Getting used to chording and layers is what allows you to eventually use less and less keys like the split 36 key board I use these days: https://kagizaraya.booth.pm/items/1235510

The term copyright misguides your assumptions I think. Apparition of printers in China, long before Westen rediscovered it, didn't lead to that kind of laws.

I mean, cultural and social structures also play a meaningful part on what is enacted.

The topic behind copyright is not simply about copy, it's about who benefit of some exclusive privileges on cultural works and what kind of social inequalities are enforcable by law.

Interesting that Kemper hasn’t been mentioned yet. They are a German company who make profiling amps, which basically consist of software able to profile an existing amplifier within ~2 minutes, and then perfectly replicating it. In an interview the inventor said that they have only on the order of 30 parameters which are configured during the profiling process, in which the device sends certain signals through the amplifier, and analyses the output. To make it stage-ready, it also has hundreds of effects and pedals (delay, wah, fuzz,...) on board.

Those Kemper profiling amps are widely used in the music industry, from hobbyists to absolute professionals. There are studios who profiled their 100s of custom amps with different mic pickup settings, and now only use the profiling amp instead. Paul Gilbert has one, and loves it, and he is reaaally picky about sound.

Apart from profiling your own amps, there is also a vast online library of profiles uploaded by community members. So if I want my amp to sound like Green Day, or just pick a certain amp like a Mark IV, I just search for that, load a matching profile into the profiling amp, and try it out. A plethora of parameters like gain can additionally be adjusted like on a normal amp - the profiling process somehow accounts for those parameters too.
It happened to me many times. So much so that I quit amazon and went to brick and mortar instead (who will often price match amazon anyway)

Amazon is welcome to sell these returns instead of throwing them away that’s not the issue. The problem was that they sell something as new when it’s been opened and used. I think no one would have an issue with it if the returned items were sold as such for a discount.
You should think of MathML like SVG. Most people use equation editors (a la Inkscape for SVGs) or a library (d3) that outputs MathML that you can include in your website. You also have the option to write simple equations by hand, but most people won’t.

Depends under which jurisdiction. The Swedish ambassador to North Korea complained to his secretary that the driveway outside was still full of snow. He was about to order some of his own men out, but minutes later a bunch of North Korean labourers appeared and cleared all the snow away in front of his embassy, including the driveway. When he asked the secretary, she told him that she hadn't called anyone. Then they both stared suspiciously at the flower pot.
