The estimates are just absurdly wrong though. Ask any investor and most will just laugh at those estimates. 99% of estimates for all companies haven’t dramatically been decreased yet. So I would take these estimates with a grain of salt.
I wouldn't oppose intentionally restructuring or regulating any of these industries. That is not what we were talking about, however. We were talking about simply letting those businesses fail, and seeing what happens on the other side of this. That could result in something better, or it could result in something worse. Given the situation, I think it's likely it would result in greater concentration. I do not think let it burn down and the chips fall where they may is a good strategy.
That last sentence means that if you want to contact distant stations, you have to connect through satellite relays or by bouncing radio signals from Earth to the Moon and back to Earth (EME)
No offense to anyone here contributing to Elm, but the project sounds like it's a dumpster fire based on the linker post.
How do you handle code challenge/exercise in your job when hiring candidates?
Hi,

I'm working on a product to improve the technical evaluation of candidates during hiring processes.

I'm curious to know how's the hiring process of your company if you use a step to send a code challenge exercise to candidates.

Thank you
Just had this conversation with a friend. We can no longer remember what the current name is of Google's messaging products. For a company that prides itself with it's brand and product management, it's ridiculous.

Wasn't it called Google Chat / GChat back in ~2007?
It makes them at least careless, and that borders on stupid.
How would a company be liable if it isn't stationed in the US nor does any business there? Asking sincerely, I don't see any way that it could be.
The N95 masks are made out of plastic, not pulp.

I looked into the pulp claim, and it's true that pulp is used to make some types of lesser surgical masks. But there's no reason to think there is anything all that special about that pulp - it could be sourced from the US too at somewhat higher cost.
Good lord man. Why not nuke all the buildings in a city and see which ones people want to rebuild?

No, a thousand times over no.

The existing meeting schedule is the carefully calibrated result of a thousand different constraints running into each other and finding a workable balance.

Why would you destroy that?

Best-case scenario, you add a ton of busy work for everyone to re-create the same thing, and everybody loses a quarter of a day trying to resolve who owns which meetings and is everyone back on them.

Worse-case, you inject utter chaos as only half of the needed people show up for key decisions and critical processes grind to a halt for a few weeks.

Sometimes I'm shocked at how cavalier some people can be about management.

So much of this conversation accepts the government’s anti-crime message is made in good faith.

Is isn't. What‘s more, you all know that. Everyone agrees the act is unlikely to to stop dedicated pedophiles and terrorists. The Republicans and Democrats know that as well. Crime is a useful pretext to openly push for what they can’t say aloud. They wish to suppress dissent.

They know the threat unbreakable encryption poses to their wealth and to their power. It’s freedom. Freedom from detection, identification, coercion to comply. Freedom to do what you think is right.

If it’s passed, terrorists will reasonably include domestic terrorist. Which will broaden to include Antifa [1] and Black Lives Matter [2] in the government’s eavesdropping. Then people who attend the same protest that BLM or Antifa appear at will need to be monitored. And so on. This is the whole point. Not pedophiles. Not Al Qaeda or Isis. They pose no threat to the power of the ruling class. You do.

Where else are you gonna go but the USD?

The second reserve currency is the EUR, the EU is already actually starting to break up with the departure of the UK, and is way more likely to continue to break up than the US.

As for CNY, China is a known currency manipulator with no free exchange mechanisms, no central bank independence, and no rule of law.

JPY or GBP? I don't see it.
Agreed completely. I think the licensing model is the issue, and if you look on this page alone people who have had to pay all say it was because of a mistake rather than as something they did because the money gave their company an advantage.

Also, I've personally tried out Qt a few different companies over the years and several of them would have been fine paying $50-200/dev/year (depending on company size), but the current price starts at $5508/dev/year! This is so much higher than Jetbrains or Visual Studio pricing that it's clearly targeting a market other than normal developers. This creates an awkwardness for Qt in my opinion. They want to build a community of developers to encourage and grow use of Qt, but most developers in the community are priced out from participating outside of open source.
If you want the feds to supply masks, they have to get them from somewhere. Furthermore, if you want the feds to supply masks, you'll get them at the discretion of the feds, not local authorities.

You're seeing what's wrong with centralized planning of things that don't need to be centralized.
They're just in it for the fame. Or the lulz.
Having spent some time in VR in the past, remapping inputs like "the mouse speed of your head" can be super disorienting when you return to the "real world," perhaps dangerously so if spent the majority of your workday in VR.

Your brain adapts, and starts to believe at a primal level that "things fall this speed when I drop them," "I move this fast when I walk", "when I point over there, it's at this angle," etc.

If anybody remembers playing GTA for too long, and later walking outside with the feeling like you ought to be able to jump in the nearest car and drive it a way, you have an inkling of how your brain gets remapped.

Remarkably quickly, moving around in the real-world can feel "off" to the same degree that it felt "off" when you first entered the VR world when you start messing with these primal feedback loops. Get ready to bump into things, and don't operate any heavy machinery if you've been in a non-1:1 VR mapping.
Is there a COTS radio set I could use for non-line of sight communication in the mountains?
> No matter how consciousness and subjective experience are implemented in the hardware of our brains, it is still a concept that we use to describe the experience, and the experience is real no matter what.

What does it mean for something to be "real"? Physics says your car is not actually real. There is no "car" particle or field in the physics ontology, there is no physical experiment we can run to definitively test whether something is a car or is not a car, such that aliens that evolved on another planet would agree perfectly with your assessments. If physics is our best theory of what actually exists, then your car doesn't really exist.

Analogously, this is the crux of the hard problem of consciousness: is the qualitative experience of consciousness actually real, or is it reducible to third-party objective facts, like every other phenomenon we've encountered, and so the irreducible properties it seems to have are actually an illusion that is reducible to non-conscious particles and fields?

Given the way you've phrased your post, that the brain "implements" consciousness, I expect you might agree that such a reduction is ultimately possible. In that case, you too might be an eliminative materialist, which asserts that consciousness does not really exist.

That said, all materialists agree that phenomenal experience requires an explanation, it's just that they assert that explanation will come from neuroscience. Antimaterialists assert that no such explanation is possible.
But $18,000 in taxes they've paid (or will pay) that should have been spent on roads, schools, hospitals and more social services won't be.

So everyone's life is $18,000 worse off.

Wow, this blew my mind! I read all the pg essays when I first started programming so I must have read this at some point!
This fiduciary responsibility is often brought up, but is largely inaccurate. Many companies, quite legally, do things that don't contribute to the bottom line, and in fact may damage it. And the courts have been fairly lenient in ruling in these companies favor.
It's very likely that the French News services will 'go dark' on Google as has happened in several other European countries. After a month or two without web traffic, there will be a rethink by the French news services.

Previously: "In Germany, some publishers [...] decided to allow the U.S. tech giant to publish their content for free after a drop in traffic."
Use "chat" instead of "communicate"? Really that does not sound like good advice to me.

Here is a tip that's really helped me over the years. Have the computer read highlighted sections back to you (via Accessibility features on MacOS, for example). I do this so often on my Mac that I have a keyboard shortcut for it; ctrl-esc. I use this feature all the time including for the composition of this comment. It is amazing to me the number of mistakes you can catch in this manner that you would not catch otherwise. The reason is your brain takes the same mental shortcuts in reading aloud (as the article recommends) as when you write.
I think Inmarsat makes a nice little unit ;)
Imo people’s love of Jupyter notebooks is another one of those “this is My Thing and I love it despite the flaws” situations.

Jupyter notebooks are painful to read, the allow you to do silly stuff all too easily, they’re nightmarish to debug, don’t play well with git, and almost every. Single. One. I’ve ever seen my teammates write eschewed almost every software engineering principle possible.

You’re not using them wrong, they shepard you to working very “fast and loose” and that’s a knife edge that you have to hope gets you to your destination before everything falls apart at the seams.
You could just as well argue that the highest levels of trade are the result of peace, not the other way around. Especially given that levels of trade were already high enough for people to make this same argument before WW1, as this book illustrates.

The article is specifically written for VC-funded startup founders. That type of company burns capital to fuel customer (not revenue per se) growth. The point of this statement (and the surrounding text) is that you can't do that now, and have to switch to preserving runway and/or growing revenue.
FT8 is part of a suite of digital transmission modes that are designed for weak signal / long distance communication. Often times these modes can be decoded even when the signal is below the noise floor.

What are possible applications?

This feels right. The site name seems to promise something it doesn't deliver: the process of production as education / entertainment. This could be a major differentiator vs bricks and mortar galleries. Lots of streams of the work in development.

Of course; it’s a remarkable feat either way.
It's important to distinguish between React "rendering" (asking components what they want the UI to look like), and actually applying updates to the DOM.

React's default behavior is that when a component renders, React will recursively re-render _all_ of its descendants. it then diffs the VDOM render output to see if you've asked for any changes to the UI since the last time it updated. If the two VDOM trees are the same, React says "nope, nothing to do here!", and ends the render pass. _If_ you requested changes, it then gathers them up and applies them all to the DOM in one step.

You can optimize the rendering behavior in some ways if needed. The `React.memo()`, `PureComponent`, and `shouldComponentUpdate` APIs [0] allow you to tell React to skip re-rendering if you know that a component's props haven't meaningfully changed, and thus would result in the same UI output as the last time. This does require that the child components be separate component types (ie, `<MyComponent />`), not just the parent rendering a bunch of plain elements (like `<div>`).

For lists in particular, React needs to know how to identify which items are which. React doesn't care about object references, but you can pass a special prop called a `key` when rendering items in a list. That way, if you move a list item up, swap a couple others, delete one, and add a couple more, React knows what existing list items ended up where, and can update the DOM efficiently in response. Otherwise, changes to lists without good use of keys can result in more DOM work being done than actually necessary.

The Spanish flu was selected for extra virulence, because it started during a war and the sickest soldiers were sent back from the front to hospitals. Usually when people get sick, they isolate themselves, so the weakest forms spread.
Great comment, thank you very much. As the Fed is not actually buying stocks, can you explain the mechanism by which its actions are preventing the stock market dipping by another 1/3 or 1/2?
It's been a few years but I remember our one needed at least 8gb ram
I got from the USA (east coast) to Tasmania on less than 10 watts once, but not on 70cm.
The book didn't argue that the war wouldn't happen, only that it would be economically disastrous for everybody involved, and thus to choose to go to war is foolishness, since everybody is strictly worse off than they were before - i.e. there are no absolute winners. Countries did go to war anyway, and, exactly as predicted, it was a disaster for all of them, proving the point.
Under a democracy, allocation of resources is always going to be driven by politics. Whether it aligns with facts, logic, greatest good, or science is purely arbitrary.
GPS satellites broadcasting L1 signals are transmitting 25 bit/s at 25.6W and they're only about 12551 miles away and moving at 8700 mph.
For some context on why this is interesting: since the dawn of radio, we've known that relatively low radio frequencies (up to maybe 30MHz, depending on time of day, solar activity, and other factors) can propagate for very long distances, by following the earth's surface or bouncing off the ionosphere. This is why a portable shortwave radio can pick up radio stations from the other side of the world.

Higher frequencies don't benefit from these effects, and generally don't propagate beyond direct line-of-sight. But in rare circumstances, atmospheric refraction can cause high-frequency radio signals to propagate much farther than normal, which is what seems to have happened here.

On a technical level, this radio contact was made possible by the recently-developed FT8 digital modulation scheme, which is designed to transmit a minimal amount of data (basically just a pair of callsigns) at only a few bits per second, so as to make even extremely weak signals detectable. The "dB" column in the screenshot illustrates that the received signal strength was roughly 100 times weaker than the background noise.
I've never understood the point of privacy without anonymity. Or of plausible deniability. Both depend on rather idealistic assumptions about adversaries.

This sort of thing is why I stopped open sourcing my work (I had several successful open source projects a decade ago). I realized that it was the responsibility of an open source maintainer to put the community first, but I was only interested in strictly pursuing my own interests. Neither side was wrong, I just realized I wasn't cut out to be a maintainer. Maybe Evan should also consider if he's cut out for the job.

Good thing we're not sheep or wolves. That's why I alluded to Orwell. The pigs from Animal Farm are a better metaphor.

The senate doesn't exist to protect the will of sheep at the hands of wolves. It exists because 250 years ago, the edit: New Jersey delegation wasn't willing to relinquish its equal power at the Constitutional Convention to a state like Virginia. Its never been about sheep and wolves, it's been about the political power of a political class that sought to concentrate as much of it as possible for themselves at the expense of others.

If you want a better way to look at it, it's a dozen wolves convincing a dozen sheep that the wolves should have twice the voting power on dinner because they have a bigger grazing area.
While this is true, it's become extremely cheap to move raw materials around these days. Shipping ore from Australia to China was at something like $8 a ton (I assume changed due to recent crisis).

I'd expect with Japan internal shipping costs may be a greater problem. They intentionally distributed their industries around the country.
>Is it better to just shut down now? For his example business, a corporate catering business, the answer is probably yes.

If privacy isn't an issue, we could insert tracking chips into the children and give them identifying tattoos, then track their locations.
Could have does not imply would have.

Neither the difficulty of planning at that scale, nor the failure modes of a centralized government entity, should be underestimated.
In this pandemic, we aren't shutting down things that are deemed essential - and any manufacturing facilities used in pandemic response would, of course, also be essential.

Whereas the current state of affairs is that China just stops exporting masks, and there's nothing we can do about it.
Has there been any work to minimize the size and number of dependencies, or modularize it, or produce a "PostGIS-lite"? Usually I'm happy to grab a good library even if it's overkill, but PostGIS pulls in many hundreds of megabytes -- far more than every other library I use combined. I wish there were a way to say "I want the GIS data types, but I don't need JPEG2000 and every other possible image format".
I don't want any third party to read my messages, including the US Government.
Laid Off ISO vs. NSO Options
Hey all,

I was recently laid off from DataRobot. Womp womp.

Anyways, they gave me the option to extend all my ISOs excercise date for a year, but to do so they will be converted into NSOs.

Is the tax benefit really worth that much more that I should exercise them now? Could I potentially be missing something else?

I think those are very good questions. Technically, they seem to use pretty ordinary gear. The bit rate is super low, about 5 bps so you're not going to be sending over your movies any time soon. It's been tried but nobody ever succeeded and conditions would have be just so for this to work.

Possible applications from a practical point of view not that I can see, though I'm sure that now that it has been shown to be possible there will be attempts to replicate it and from harder locations.

But HAMs are known for doing things the hard way, after all, you could just pick up the phone and talk, that's not what this is about. It's about being able to do it, just like mountain climbing.
No idea who or what youre talking about, but I’m sure youre not achieving whatever it is you set out to achieve here.

A related anecdote: I seem to recall a team from another country (Israel?) not being able to attend the world championships, but they were able to send their robot, and coordinated with another team to have that team operate the robot.

But yeah, a match is 2.5 minutes; and only in the first 15 seconds is the robot is entirely autonomous, for the remainder of a match there's a 2-person drive team (plus maybe a coach standing behind them) operating it over WiFi, and also a human player that is able to interact with the field from the sidelines. Nevermind all the activity in the pits, repairing and adjusting the robot.
UHF is line-of-sight. The article speculates about a transient effect ("marine ducting") that allowed the signal to propagate further this time. It's not likely to be reliably repeatable.

FT8 is ~10 bits/second (think of it as CW/morse code + better modulation + forward error correction).
> And how's that working out for Sweden? 20x death rate to date compared to neighboring Finland which has a lockdown in place, and an ever accelerating rate of infected. Cool, cool.

Think about it: if you allow it to spread, then yes, you will see people die. The same is true of the flu, which has so far killed more people in the same period of time than COVID has according to the CDC -- in every age category [5].

I bet flu deaths are plummeting in Finland, too. I bet you anything that Sweden has 20X the death rate from the flu as compared to Finland and Denmark. Because nothing spreads when you're locked in. But it would be absurd to lock everyone inside because of the flu right? It's a question of risk management not risk elimination. [1]

And they're quite right, that they will be safe from a second wave as no other country will.

So, to answer you question, it's working out well.

> Also China today is nothing like China pre-covid. Mandatory mask wearing everywhere, temperature checks every few blocks, in every shop, mobile codes to scan certifying your virus free status before being allowed to buy anything. They're not exactly planning their next Disneyland trips over there.

1. They wore masks anyways due to the pollution ([2] this photo is from 2013 not 2020).

2. They had police/army stops anyways due to the PRC government being totalitarian. [3]

3. They have actually re-opened Shanghai Disneyland, as of March 9th. [4]

Sounds pretty similar to me.

It’d be awesome if you could do this natively on the Quest (sideloaded). Native gesture control, inside-out tracking, wireless, almost twice the resolution, and wouldn’t even need to be connected to a PC at all so could be used anywhere (with Bluetooth keyboard and mouse).
