I find the concept interesting and I can see real applications for something like this (delaying someone's access to a file). For example, one could use that to disseminate press releases ahead of time without actually revealing the contents.

That said, it seems the current implementation is impractical because you will "on average" decypher after a certain time, but that time can vary greatly. Are there plans or methods to explore in order to make this more deterministic?
Minor clarification/nitpick: shorter half-life is generally considered more dangerous, all else being equal (which it never is, especially if you're using Ci or Bq as your units, which correct for this by being disintegrations per second).

The extreme example of this is Bi-209, which has a half-life of order 10¹⁹ years. Of course, it's perfectly safe to ingest, especially with pink dye and a nice bottle!
That sounds like an ad for some lifestyle product, not reality. Frequent in-person meetings aren't that important to the economy. It's cheap, quick and simple transport of goods throughout Europe that is important, not some executive traveling to four countries in an afternoon.
So far I think it's anyone's guess how things will shake out, though I'm still hoping for a "return to normalcy" with reduced trust in the government. Do you have a different theory on how things will look going forward? If so, I'd appreciate a different perspective.
Yes, I'm aware that's what he was referring to, but it's not the entirety of the tax burden in the US, and even people who pay nothing in income tax still pay taxes.

This is precisely why a flat tax disproportionally impacts lower income people.
It's also different from how Common Lisp handles default arguments, and ... how C++ handles default arguments.

I think the other thing to worry about with live updating is client interaction security footprint. In most platforms you better be damn sure that your client rerendering code is bulletproof, because if an adversary finds an input permutation that hogs CPU or worse, panics your backend you'll really be up the creek, though Phoenix/liveview can take advantage of erlang process isolation in a way that it's way less of a concern.

Amazon is very well known for having A LOT of middle managers too, so I'm not sure it's a good example?
Well that's just reinforcing their point. Do you have any idea how much Google spends on creating some semblance of "search quality benchmarking" that actually means something? I'd venture it's way, way more than you imagine.
Yes, Musk is the example here but I don’t think that it’s that hard to implement this, simply because there are many many cults out there that function in similar manner. Probably there is a formula for that.
As so often is the case when quoting Strunk, he violates his own rules.

"Vigorous writing is concise and should contain no unnecessary words or sentences. But the goal is not conciseness per se, rather that every word tell."

The analogy with machines unnecessary; the analogy with drawing incorrect; the hypothetical writer a distraction.

And yet, it's not as forceful. Maybe he's just plain wrong?
Why don't you share your insights?
That's how immunity against pathogens usually works. There are exceptions like the flu which mutates into sufficiently distinct strains that the immune system doesn't (fully) recognize. I'm still oversimplifying here.
Containers are basically a very thin layer on top of namespaces and cgroups, which are most definitely in kernel primitives.

Docker adds packaging and distribution, but the hard work is in kernel.
I think it's an overstatement. When you recover from it, you don't still have it, even if you test positive. That means that at least some of the "got it a second time" reports are false.

Are they all false? Don't know. There's hope, but not yet evidence, so far as I know.
As a mathematician I can tell you that game theoretically, Alabama is not able to bail out anyone. They use more money than they contribute to the country. I think a better example would be should Texas or Massachusetts be obliged to bail out California.

I guess I don't understand why more people aren't asking for a solution that allows them to sustain themselves and their families and also doesn't elevate the risk of spreading COVID-19. I don't get how "end the lockdown and let a bunch of people get sick" or "possibly starve homeless in the streets" became the only two possible options, and I don't get how anyone becomes a staunch advocate for either.

>in other words, when you recover from covid-19, you are immune

Well, it may appear to be the case so far but afaik that hasn't been rigorously confirmed, and this article doesn't imply immunity to live virus upon reexposure.

>but that doesn't mean the virus is some sort of strange monster

Except there are dozens of papers being publishes about a range of effects - damage to a multitude of organs, virus fragments found in brains during autopsy, high incidence of clotting/stroke. By many SME accounts it is very much a strange monster. Also recall the documented rapid progression from asymptomatic to dead.

>It's extremely infectious, and somewhat more lethal than influenza

So one of these numbers (CFR) is about the same, but the R0 is anywhere from 2-4 times larger, and the critical rate appears to much higher than the typical flu. So the response of "terror" isn't totally unwarranted.

>When I first heard about those patients who had recovered from the virus, and yet were still testing positive, it felt like a mistake. I'm glad it's been cleared up.

Agreed. And another reinfection case occured in an immunocompromised patient. So it's looking like the infection doesn't become chronic or dormant.

There’s a PARC paper from the Cedar team benchmarking base-and bounds vs marker-terminated (e.g. null terminated) strings and base-and-bounds won hands down on a variety of use cases. Won on speed, not just the safety grounds. In those days some people actually worried about the space taken up by the extra bounds variable.
Wow; not too many HNers are in a union, I'd guess. Next thing you'll be telling us is that you have a pension.

Of course, if the company goes bankrupt, all bets are off. Or even if things get so dire that the company manages to claw back some benefits in the next negotiation. Seems unlikely though.
The article doesn't say what you think it says.

>One of the most common questions about the Federal Reserve is this: Does the Fed print money?

>There are really two ways to address this question. In terms of the actual, physical printing, no, the Fed doesn’t actually print or produce money in any form. Coins come from the U.S. Mint, and paper currency comes from the U.S. Treasury’s Bureau of Engraving and Printing. The Fed distributes currency after it’s printed.

>However, what many questioners might really be asking is whether the Fed has the ability to control how much money is in our economy. That’s a different story.

>The Fed adds to (or subtracts from) the amount of money in the economy by buying (or selling) U.S. Treasury securities and other financial instruments. This is referred to as “open market operations,” since these transactions take place in the open market. (The Fed isn’t allowed to buy securities directly from the U.S. Treasury.)

>The Fed pays for those securities by crediting funds to the reserves that banks are required to hold, either cash in their vaults or deposits at a Reserve bank.

>“So, in that sense, we can think of ‘printing money’ as adding reserves to the banking system,” said David Wheelock, vice president and deputy director of research.

Six months is before the pandemic really set in though. I really don't think that stock prices at the end of October had the pandemic priced in.
Presumably there's more valuable data than just maps. I would imagine that Lyft could give valuable real-time data like areas of the city where there's traffic congestion and slower drive times. It's unclear how you'd value that, but it seems like an acquiring company would get more than just raw map data for all available streets.
There are no savings on the federal level (or any level, really). Federal, state and county level are generally driven by debt and steadily increasing their budget due to mission creep.
Intuitively I think it is because "root" means "origin" (e.g. tell me about your roots i.e. your family, or the root of all evil etc.), and the top node is where you start when navigating the tree (it would be the memory reference you have first because it is stored in a variable, and you need to traverse to get to other nodes).

Using a physical tree analogy I'd call it a trunk rather than a root (and ignore that a real tree has roots entirely because they are a tree in their own right!)
Historically, pension benefits were one of the main benefits unions fought for (and won) so that their members could have an income in their old age and retire.

Today, very few workers still have pensions, but the few that do tend to be those represented by a union. In many states, this includes government employees: teachers, firefighters, police, etc.
> Most web developers are probably not particularly concerned about how fast their code is in relative terms.

Absolutely. As long as our app performs without any input lag on IE11 I'm happy. Our users don't care and our higher-ups don't care either. They care that we built out new features quickly and have a better user experience than our competitors. If React lets us trade some minor rendering performance for better developer productivity it's doing it's job.
Stock market is a predictive pricing mechanism. It prices assets based on future expected returns. News about the economy is history and hence it is already priced in.
I also struggle with this, and this is my theory:

In 2008 every day brought in bad news, with more and more banks failing, home being foreclosed, bad financial numbers, Congress trying to bailout .... which led to overall bad sentiment and the decline in stock market.

Right now, if I look at the new cycle what do I see: A city wants to open up, layoffs, a state wants to open up, stimulus money, people on the beach, layoffs, more stimulus money, GDP down, virus in works, 20% in NY may have been infected, Remdesivir is working....

So, is it a bad news or optimistic news? It's all mixed in. No one knows how to process medical side and financial side together. On top of that there is a lot of liquidity in the market. So, what happens, it ends up in the stock market thus inflating it.

I think there would be a massive whiplash once we start seeing higher unemployment numbers and the real impact of March-? shutdown and see a massive drop in the stock market.

But who knows??
The back-to-work strategy will most likely be led by large businesses. They have resources, they will decide what strategies they want to follow, and they're all working on that now.

And really, no one can argue with them on that. A governor or president can order businesses closed, they can lift that order, but they can't force businesses to go back to work before the business leaders and customers are ready to.

What governments need to do is clarify the new rules of the road for businesses. For example companies that used to be heavily restricted on how they can use health information are now going to need to test all their employees, make decisions based on those test results, provide protective medical equipment, etc.
>And I specifically use deplorable to call out the political excesses of my own accustomed "tribe."

And, either purposely or naively, you're misconstruing the context and scope of a single quote as if you were a part of the other "tribe."

The "basket of deplorables" comment is widely and incorrectly assumed to be an expression of elitist disdain by "the left" for all rural white males, all Trump supporters, or everyone of lower socioeconomic class, when it rather explicitly referred to the - and I'm paraphrasing almost directly from the quote here - "racists, sexists, homophobes, xenophobes, Islamophobes" who took over Trump's base and steered it in an extremist direction. In other words, people who should be considered deplorable.

It may not have been a precisely worded criticism but it was an accurate one.
It's worth pointing out that Google cripples its apps in Firefox intentionally and since Edge is now basically Chrome, MS probably, (perhaps unintentionally?), follows suit.
That depends. How much liability and risk is Google taking on by being more hands-off? From this perspective, it's understandable why Google would wish to delegate medical judgments to a known institution, similar to how the rest of the video content industry delegates to the FCC.

I'm sure Google would like to have no risk and simply host pirated content like they used to.
> I'm not quite sure if the states are hoping the federal government will come out with some unifying strategy/process/materials/procedures at some point, or what, but it sure ain't happening.

They're not - most of the megaregions are forming interstate compacts to coordinate medium to long term strategy. Colorado and Nevada just joined the Western States Pact which CA/OR/WA started a few weeks ago around the same time the East Coast created their own. I think the Great Lakes states have one as well.
Perhaps because the claim "The way EU works is by letting monopolies in a few west European countries expand their market to east" is clearly ludicrous as a summary of how the EU works?

I mean, the EU - ignoring the name changes over the years - had existed for over 30 years before the fall of the Iron curtain and nearly 50 years before admitting new members from the the East. The idea that the whole thing was set-up and run based on the goal of economically exploiting recent entrants from the East decades in the future is simply silly.
Invidio.us seems unusable.

I tried to do simplest thing: create playlist - the only thing I'm really missing not having YT account (beside commenting).

1. First of all, it forced me to create Invidio.us account. Why it can't store everything in my cookie?

2. Next, I searched for a video typing its YT code "fVCAFvIq_F8" - no results. After several attempts I figured out that sometimes it does find it and sometimes it doesn't. Weird.

3. Alright, I copied full address of a video into search box, clicked on result - and got an error: "The uploader has not made this video available in your country." Umm... What? I have no problem watching it on YT itself, why would Invidio restrict me? But even if it was country-restricted, why would Invidio reproduce this stupid Google-imposed geographical restrictions/discrimination?

3. Very irritated, I went for another video (OlNC6gK2y0I) - only to get another error: "The media could not be loaded, either because the server or network failed or because the format is not supported" ...

4. It was getting boring, but for the sake of experiment I went for yet another video - Invidio found it and played, but... there is no "Add to a play list" button? Turned out, first you need go to a settings, scroll down, find and click "View all playlists" link, on the next page click "Create playlist" link, on the next page create it, then go back to a video you wanted to add and add it. Thats... a clusterfuck.

5. Alright I go to a front page - where can I see my playlist? Nowhere. You need to find and turn on separate setting just to get "Playlists" link on the front page. (Isn't it obvious that I need playlists from the very fact that I created it?)

OK, maybe at least Invidio has additional functionality compared to YT, like downloading video? No, "Download is disabled." Why?

To all of that I must add that Invidio.us worked very slow, sluggish and unresponsive. Occasionally I was getting "Rate limit exceeded" error just trying to open front page.
I just go to their website so I don't know, sorry.
> If you rent for 30 years, at the end of these 30 years you will have nothing

That chestnut again. It makes me sad to see it on HN. It's just a dishonest comparison.

The money saved by not paying back a bank loan plus interest goes into long term investment, not into consumables. In most places on the world, for the last 40 years, the renter comes ahead of the home-owner in spe in terms of total cost.
As it is so often the case, the choice between monolith and microservices is not a binary one; rather, it is a sliding scale between two extremes.

On one end we have a real monolith: a single executable binary, with no external dependencies apart from the OS bindings. This is very rare in practice, and most commonly found in games and probably mobile apps; when it comes to Web-based services, even a traditional idea of single-codebase app usually has a SQL database as an external dependency.

On the other end of the scale there is a complex system consisting of hundreds or even thousands [0] of tiny services that require complex orchestration mechanisms such as a service hub or service mesh.

So each team (in a wide sense: could be a company, organisation, department etc) needs to consider where they fall in the continuum, considering a) which architecture will provide most benefit while b) still being maintainable by the team; both the architecture and the team need to evolve together.

Six tips for running more productive remote meetings
Viruses don't work that way.

Even if they did, it's not the point -- the presumption is that the immune system would handle them like it treated live viruses, with antibodies and an immune response. The point is that this isn't a second infection, it's dead fallout from the first one, and the patent is likely immune against reinfection.
The most annoying is the way it handles updates. There's no easy way to turn off auto-update (I get updates via my package manager), and the functionality in Firefox is completely broken. It downloads the update and then refuses to open any pages until the browser is restarted, but the restart functionality is broken, and it just exits, losing all of the tabs that were open.

It happened again one day, and when Firefox exited I just started Chromium up instead.

It feels, to me, that Firefox and Mozilla have a very annoying "We know better than you" attitude towards a lot of things. That's great for people who want that, but I don't.
> somewhat more lethal than influenza

My understanding is that most evidence points to order of magnitude more lethal even when the hospitals aren't overflown.

Regarding "testing negative then positive" the experts already expected that there were no real reinfections.
That doesn't strictly follow.

Here is the thought process, though. Typically when you get an infection, your body builds antibodies that can attack the pathogen. The next time the pathogen shows up, your body kills it before you get sick. This immunity doesn't always last for a lifetime, but there is pretty much always some immunity. With COVID-19, early reports showed that this wasn't happening; people got sick, recovered, and then got COVID-19 again. What the news article says is that the test was wrong; when they tested positive the second time, the test was just returning incorrect results (because of limitations of the PCR technique; it's testing for certain RNA, not for the existence of an infectious live virus).

So to say that this means you can be immune to SARS-CoV-2 is not strictly correct. What it says is that there is no reason to think that this virus is any different from many of the other viruses that we already know about. (We do know about viruses that you can't be immune to, like HIV. But those viruses explicitly attack the immune system machinery that is supposed to kill them. We have no evidence that SARS-CoV-2 does that.)

That may be a point for the US, but not so much for Germany. We already only have air travel between major cities as the country isn't that big. We do have small regional airports, but they are mostly for hobbyists and private planes, not for Lufthansa & commercial airlines.
> the default value does not have to be a literal value

The default isn't a literal value when it is [], by the way.

If [] were a literal, then this would not be safe or correct:

def fun():
local = []
local.append(3)

The fact is that whenever [] is evaluated, it produces a fresh list each time. It's a constructor for an empty list, exactly like set() for an empty set. It just has slicker syntactic sugar.

Python just calls that a literal because it looks like one.

Looking is being, in Python. Except for all the pitfalls.
Journaling Prompt Generator for Covid-19
Alabama gets ~$3.50 form the federal government for every $1 it contributes in federal taxes. California gets ~$0.97 for every dollar it gives. So the real question is should Californians be bailing out Alabama all the time. Should states like South Carolina, Alabama and North Dakota just be left to die? I mean they are takers in even the best economic situation.

The answer is of course not, they are states populated by real people who live under the laws and economic system of the United States Federal government. The government should ensure that all people are entitled to enough funding to provide opportunity, health and justice. We don't just leave people to suffer regardless of who they vote for. At least we didn't used too.
And a tremendous amount has been done to mitigate risk for sales. Curbside pickup; delivery; masks and shields; repeated sanitization.

I got to believe we're not arguing in good faith here any more. Goodbye.
