This makes no sense, because the only reason React would suddenly fail on you is if your project is so very badly engineered that you don't pin dependencies and cache them locally. And even then, your deployed instances would remain unaffected.

A dependency is something you own (a checked-out copy of). A better comparison is with services. So you may be using a payment gateway in your product, and maybe you need just a single one - but at the very minimum, you should have a plan in place to switch to a different one at a moment's notice. That's reasonable redundancy.

I think I've come up with an analogy for demand-side supply chain issues though. Imagine you have a web service that's constantly under 90% load during normal operations, and that eats almost exactly as much money in the infrastructure costs as it earns. Imagine that service gets mentioned on Hacker News. It almost immediately fails due to increased demand, you can't provision new instances because you don't have enough money in the bank, and then when suddenly the demand drops, you can't afford to keep it on at all.

Only a series of very bad decision would cause the above scenario to happen, and yet it's almost exactly like how supply chains operate in physical space.
Python's time.time() call is also going to be affected by system time changes and thus not guaranteed to increase uniformly. So Date() in Swift and time.time() in Python are the same in that regard.
how is this shit even legal? I mean, assuming there are laws enforcing any semblance of "best practice" in a country? where are they incorporated?!
If Signal were federated, there would be no single entity to shut down. Alas...
I mean the Fed's actions will increase the nominal value of bonds, but this increase will be due to inflation rather than because they're paying more than the rational valuation.

Usually it's more people who get laid off start talking about it on Twitter, then the news media get wind of it and start talking with the laid off employees, and find some willing to describe in detail exactly what went down, send along a screenshot of the announcement email, etc.

If I got laid off I'd talk about it on Twitter too. That's a natural reaction for many people. You want to commiserate with others in the same situation and share useful unemployment and job-finding resources. Hell, a big layoff gets its own hashtag.
I don’t think you can claim definitively that that is why Uber lost. Uber lost in other markets too, like in Southeast Asia.

I don’t think anyone can win this argument with you since you can always claim that the Chinese government favors local companies, so therefore ____ lost.

But at least I can give some counterpoints: Tesla hasn’t lost in China.
One other thing is that the dimensional restrictions often apply only to "permanent structures." You can sometimes get away with larger buildings because in many locations if you don't have poured footings or a foundation, the structure isn't considered to be permanent.
There aren't a lot of jobs that can really use the 'space' provided by VR. I think the adoption here would have to drastically outpace multiple monitors and OS workspaces and keyboard shortcuts. I can easily get to 10-20 tabs in VS Code or a browser, but my attention is only really ever on one at a time. If I have to search through them, I'll have to do that on a monitor or in VR. I might be able to organize better in 3D: HTML files on the left, CSS files on the right, JS in the middle, backend reference above, tools and console below (like 5 monitors in a plus pattern).

I'd need probably a dozen or so channels of information that I had to cycle between quickly to convince me, given I've gotten used to multi-monitors, workspaces, and keyboard shortcuts. Maybe some futuristic high level analyst job that needs to look through lots of different kinds of information (geographical, text, videos, etc) at once.
In terms of military might, yes. In terms of economy? We'll see when the pandemic passes. The thing I see is US being too slow to react to COVID-19 threat and its economy being probably one of the most fragile (because of being most market-optimized).
Hi - I tested this for you, just so you know you have a message in your payment form that may need to be changed"100% off Sizle Pro monthly subscription for 12 months." but you said no end date in your post. The error checking system is forcing a credit card even though there is no charge.
Yep! :) Sounds like you've thought it through and I see your point.
Not ELI5 exactly, but the article does a pretty good job of explaining in the first paragraph:

> The default mode network (DMN) is an internally directed system that correlates with consciousness of self, and the dorsal attention network (DAT) is an externally directed system that correlates with consciousness of the environment... the DMN and DAT appear to be in a reciprocal relationship with each other such that they are not simultaneously active, i.e., they are “anticorrelated.”

The "temporal circuit" the paper describes is the neural architecture that facilitates the transitions between these two networks.
Hi, author here, thanks for taking the time to read the article!

The objective of the demo was not to see which language could sum up a bunch of numbers the fastest. You could keep optimizing that until you are left with just `print(<the resulting number>)`. The objective was to have a simple example of looping over an array a bunch of times. The only reason I ended up summing the numbers in the array and printing them was so that LLVM wouldn't optimize it away and be unfair towards python. I actually wrote it first in Python tbh.
Thank you kind stranger :)
The Seattle Art Museum does this. There's an attached/affiliated gallery that sells art, and also provides rentals, as long as you're also a member of SAM. It's 10% of the price to rent for 3 months, renewable once, and if you decide to purchase, half the rental amount goes towards the purchase price. I used it quite a bit when I first began collecting art.
So, I was under the understanding that Safari was dragging their feet on the whole WebRTC thing, and if they had come out with it when Chrome did, that these types of apps would then be able to run in the browser (just like Jitsi does today, I presume).

I know that companies have a perverse incentive to sell your info to advertisers and such, so I'm not trying to wave that away.

Just wanting to understand if Safari DID have webRTC much earlier, would we be talking about Zoom today?
In my case the first sentence was the title and the second the body; I guess having the 2 together might’ve thrown it off. I didn’t know only one of the fields was actually required.
This looks very nice! I've been thinking about something like this for quite a while. May I suggest two additional features that I would love to see in such a window manager:

1. A way to neatly arrange all the windows on a virtual sphere that surrounds the user, possibly arranging them automatically in a similar manner as a tiling window manager.

2. A way to rotate the before-mentioned sphere around you without forcing the user to rotate it's head. This would avoid much of the neck strain. It could be done by, for example, holding a button on the keyboard while moving the mouse or by a simple keyboard shortcut to rotate the sphere by X degrees in any direction.

This concept could also be extended to virtual desktops where each desktop is a sphere around the next, like an onion, with the ability to "zoom" in to the next desktop.
I sincerely hope most foreign businesses move their factories away from China.

On top of that, China has to be held responsible for crime against humanity and must be punished.
For instance this makes it fake:

"Unsurprisingly, Sweden has received no assistance from China. Instead, one of the country’s hospitals had to secure philanthropic funding to buy Chinese medical gear. Sweden happens to be China’s European bête noire, the result of its support for the imprisoned Hong Kong bookseller Gui Minhai, who became a Swedish citizen in the 1990s."

"Though an airplane would reach the desperate Spaniards (some 85,000 coronavirus infections, more than 7,000 deaths) much faster, Beijing made sure that the Chinese supplies currently heading for Spain would travel by train along the Belt and Road route, a journey that takes 17 days."

"Some propaganda campaigns are more brazen still. According to recent analysis, 46% of tweets using the hashtag #forzaCinaeItalia, which translates as “come on China and Italy,” were generated by automated bots. For #grazieCina, meaning “Thanks China,” it was 37%. China’s Foreign Ministry Spokeswoman Hua even posted a video on Twitter of Italians in Rome applauding health workers at noon from their balconies—but dubbed with the Chinese national anthem and claiming, spuriously, they were chanting “Grazie, Cina!”"

Yup. I don't like Yelp, but in this situation the choice isn't between layoffs and no layoffs, it's between layoffs and bankruptcy. And in bankruptcy you'd see massive layoffs anyway.

There's not really even a choice here.

I can see how that would lead to an illusion of continuous subjective awareness, but I don't think it supports the notion that subjective awareness is entirely illusory. I think therefore I am, the existence of qualia [1], etc.

Well, now about a half of decade passed since that expert opinions were raised. And no data-breaching bugs were found in Telegram, but there were plenty of them in WhatApp.

Surely, that doesn't mean that expert were wrong, but at least mentioning that in Telegram vs WhatsApp debate doesn't look like a strong point.
Because while payroll is a cost it is not the only cost that a business that no longer has any revenue needs to cover. The maximum amount of a loan is 2.5 times the verified payroll. That's 2.5 months of pay. The rest of costs still need to be paid, except there's zero guarantees that the revenue of a business is going to recover immediately after the stay at home is lifted [it won't immediately recover] and it is unknown when the stay at home would be lifted. Lets presume that all other costs of running a business are added to some other loan. That loan is not 0% and it is personally guaranteed.

This means that by taking this loan and spending it on a payroll for next 2.5 months, the owner of the business in a month number 3 is in a worse position than the owner of the business would have been today if the owner were to simply lay off everyone.

The only winners in this are banks making a percentage of a zero risk loan that can be serviced at an incremental cost of a couple of dollars (electronic payments). It is, frankly, disgusting that the congress yet another time took small business loans as a base and made it a money stream for banks.
Beatsaber is really fun as well!
Yes, there is a thing called corollary discharge in the human visual system that keeps the world steady as one glances around (in the real world). Changing the direction one is looking causes the image to shift rapidly on the retina, yet perceptually we see a world that is not wiggling.

Corollary discharge[1] causes the brain to “subtract” out the motion of the image on the retina. It happens when our nervous system instructs the eyes to look in another direction. You can have someone else move your eyes or even do it yourself by pressing gently on the side of the eyeball with a fingertip on top of the lid. Wiggling one eye this way is not supported by the hardware of the eye and produces a very noticeable wiggly view of the real world.

I mentioned subtracting out the motion going on in the visual system. Experiments suggest that something like this is happening. If a muscle paralyzing drug is injected into the eye’s muscles it causes a wiggly world because the intent to glance somewhere causes both an ineffective command to move the eye, producing no real movement of the image in the retina while the triggered corollary discharge subtracts the intended motion from the still image and causes a perceived motion (in the opposite direction).

I'd say the culture is very, very different. Java/C#-heads are in love with OOP and create layers on layers everywhere, hiding as much state and methods as they can (you can't use this operator, you'll shoot yourself in the foot!) and rarely doing pure functions. It's just a long way from how math works.

Not saying it wouldn't work, it definitely would, but I think I'd rather switch profession than deal with Maven and Eclipse in 2020.

Swift culture is more about having non-mutable structs that in turn is extended via extensions and heavy use of copy on write when mutable structs are needed. It's a small difference but it's there.
The moon is at the bottom of it's own rather deep gravity well. Landing equipment and men there is many times more expensive than putting them in low earth orbit.

Returning mass from the moon takes about two thirds the delta v of just getting something into LEO from earth, and that fuel has to be shipped from earth, so another order of magnitude more expensive. That's why the Apollo lander returned so little mass.

And moon projectiles take days to reach Earth, are easy to track and intercept.

So no, putting kinetic projectiles in LEO is far cheaper, far more accurate, far harder to stop, and can hit targets within minutes. A Falcon Heavy could lift 100,000 lbs of "rods from god" with fuel to LEO for less than $150M. That would only get a few thousand pounds of equipment/fuel to the moon.

The moon has no military value for Earth. Far too expensive, far too far away.
While job losses will pile further misery on the economy, I hope that means there are now fewer ad sales people trying to shake down local businesses so that they offer Yelp protection money to keep their ratings positive.

Companies like this always start with a noble purpose, before the pressure to monetize causes them to ruin what was once a valuable service.
From what I remember, each disk was roughly a single "island". I think they tried to keep it semi-logical but I doubt it was as effective as they would have liked.

Nations were useful, particularly when almost all problems were local problems. Doesn't mean it's an ideal top-level organization for XXI century.

You have bodies like Germany or the US, which function as a federation of states. Looking at Germany and EU, you essentially have states within a state within a sort-of state. You can stack governments recursively, so it's possible and in some ways desirable to have a single one at the top level.

If anyone wants to find out more on what Cormier wants to focus on over the coming years, he did a small QnA: https://www.redhat.com/en/blog/get-know-red-hat-president-an...

It will be interesting to see, how his management style is going to impact Red Hat over the coming years. Considering his background and acumen, I feel like there is going to be a stronger focus on tailored services and specific solutions for organizations. They are already very active in the health care and financial industry, so this could be an area they might expand.
This is a solution that, if done "perfectly", should be able to catch 100% of spam submissions. This is in contrast to things like captchas (because they "test" something other than the end-goal [no spam] to guess at whether something is spam or not, while ignoring spam from humans [or humans filling out captchas on behalf of bots], and cause problems for both humans and benign bots).

Obviously, it's an extremely hard problem that is hard to do 100% correctly. But it's a viable non-lazy solution (that still needs a lot more work than the current state-of-the-art implementations) compared to the lazy solution of just putting captchas on the page.

The ideal solution would get rid of spam without inconveniencing users who aren't submitting spam, I'd think, which means captchas aren't it.
If you have access to an infinite number of CPUs then every problem can be solved in finite time. This is clearly obvious conclusion (excepting perhaps problems which involve transfinite numbers, in which case you need to pin down which infinity you mean).

In the real world, communication is limited to the speed of light.

If your message is going out to the "infinite number of mathematicians", then after time T your message reaches 4/3 π (c*T)^3 of space, which is polynomial in time. You therefore cannot contact an exponential number of mathematicians, which is what you would need in order to demonstrate the trivial reduction of an NP problem into P.

See https://en.wikipedia.org/wiki/Limits_of_computation for other real-world limitations.

You mention "twitter ... where it's quite possible to send messages instantly for all practical purposes."

There are fewer than 10 billion people in the world. That's a finite number. Even a quadratic problem remains quadratic if there is a bounded number of compute resources. (Any finite number of people/CPUs will be a problem, even if the entire galaxy were populated by humans and/or computronium)

Consider https://en.wikipedia.org/wiki/Ramsey%27s_theorem#Ramsey_numb... with the famous description attributed to Erdős:

> Erdős asks us to imagine an alien force, vastly more powerful than us, landing on Earth and demanding the value of R(5, 5) or they will destroy our planet. In that case, he claims, we should marshal all our computers and all our mathematicians and attempt to find the value. But suppose, instead, that they ask for R(6, 6). In that case, he believes, we should attempt to destroy the aliens.

Even with the entire mathematical population of the world working on it, Erdős doesn't think R(6, 6) solvable in reasonable time. Now try solving R(n, n). Can it really be solved in linear time even if the entire world becomes proficient in mathematics?

There’s a rumor some company in SV, some time around the new millennium, was looking for a routing/router expert. I have no idea how the interview proceeded, probably done by a non SME, anyhow, they ended up hiring a guy who really knew routers, except the ones to work on wood. I think they kept him and he learned on the job...

I’m pretty sure you never focus on anything up close in VR. It’s all “far away”, as someone who is near sighted I absolutely have to use glasses in VR. I suspect but am not certain some far sighted people might not need correction, as something may seem close up but really it’s just “big and far away”.

Try it!
I have a hypothesis that people treat open source a little like the way that some managers and product managers treat software engineers — as dispensable, as people that shouldn't have authority or control, as people that don't know what the best is for the product. Unfortunately this isn't true. Empathetic makers — the ones that are most successful — are often deeply in touch with (a) needs of customers and (b) know what they are capable of offering. Unfortunately, what individuals offer is often not thought of as a gift (in both the open source world and in business), but rather as a given. This orientation is harmful to the human spirit, but unfortunately we have grown used to it in our world of seemingly endless commodities.
In a past life I did some real wizardry with dynamic in C#, drastically improved performance on a thing that had been using strange combinations of T4 compile-time templates, Reflection.Emit, and some very kooky multi-database lookups with a custom IDynamicMetaObject provider.

It was definitely worth the effort then. I also recognize why it is a very unlikely scenario to repeat.

The other place where I used dynamic most heavily in C# was that it was really great for IronPython interop where you could have a bit of "data science" done in a Python module, build that to a .NET assembly and call into the Python module from C#. (Though the other direction was more common, using IronPython to do data science around a bulk of C# models and code.) With so much more data science since that past life of mine having moved to Python, it's almost a shame that IronPython hasn't really kept up.

>We demonstrate that the transitions between default mode and dorsal attention networks are embedded in this temporal circuit, in which a balanced reciprocal accessibility of brain states is characteristic of consciousness.

I read it is as the temporal circuit manages the anti-correlated relationship between the two networks to produce consciousness. Almost like the temporal circuit is a function whose goal is to return 1 given two anticorrelated inputs that add up to about 1 and the computation to arrive to the solution is what consciousness is. Weird unresponsive stuff happens when the sum of the inputs is above 1.

Consciousness is an emergent side effect of trying to keep two input systems synchronized
It is a good story as in if they didn't do what they are doing today - say every healthcare worker quits tomorrow, we are in a huge trouble.

They are identical to soldiers. Some healthcare workers are being exposed to Coronavirus and dying.

In fact, we should have similar veteran-like benefits for healthcare workers for their sacrifice during this time. Same with delivery workers - they are the logistics arm of this war.
The bill seems like it would result in forcing e2e out of the market. Each product that offers e2e would then need to make a choice. Remove e2e or keep e2e. If they keep e2e then either they proactively dump the US market or they face legal peril. It seems like the same thing to me.

They don't want to offer a product that doesn't support e2e.
I agree, working on small teams and on bootstrapped apps it's just hard to imagine 1000 engineers or even 100 engineers working on a web application.
I don’t know about you, but I don’t often feel a yearning to have a brand new language feature that’s never been thought of before; if it’s never been deployed in any existing programming language, you’ve got a whole lot of ground to cover to even just prove it out.
