> In all settings, viruses need water to survive. "Viruses can withstand a small amount of dehydration," says Dr. Paul Meechan, a former director of safety at the Centers for Disease Control and Prevention and president of the American Biological Safety Association.
One thing to note is that in your calculations, you are using 50cm distance, but in the study you linked, they are using 3 cm distance. Since this is inverse square law, that makes sense it would take longer to deactivate.

For another point of reference, this study[1] says it takes 1.8 J/cm^2 to deactivate the flu virus. I'm not sure which is more hearty but from my calculations, it seems as though it's similar (about 2 J/cm^2). If that's the case then if you brought the intensity of your light up (bring the bulb much closer and possibly wrap it in material that reflects UV-C if that's even possible) then it would only take seconds to deactivate the virus.

NRA sues California Gov. Gavin Newsom over gun store closures
hey! relevant anecdotal data here. I work in an automotive repair garage. Anyone who has to drive a vehicle dropped off by a customer has to make sure its been UV sanitized first. We drape a 40 watt CFL UV lamp from your rearview mirror, put your floor mats on your windshield and rear window, and cover the windows with scratch mats for 35 minutes. After the timer goes off, a big blue sticker goes on your window. We then do it all over again before we give the truck or car back to you.

We had 2 ozone generators we were using (normally to remove cigarette smoke from car seats) but they take hours. the bulbs are cheaper and faster!!
When it happened to me (before all this, summer 2019) they gave me a FedEx account number and asked me to FedEx it back. It was a company account so I just had to show up and make a minimal effort of stuffing it in a box. And I was across the country from HQ. I imagine even with people stuck remote even in the same city, they could just do the same and have people FedEx it back, either now or later.
Surely a Freakonomics question.
the corona virus (similar to the HI virus) has an envelope which is a lipid bilayer, there are viruses without an envelope. Now you may think that a virus with an envelope is more stable than viruses without, but the contrary is the case. once the bilayer tears, the virus is dysfunctional.

Also, what is not always talked about in the media currently is, that not all viruses are replicated functional. In fact, a large fraction of viruses produced are not capable of infecting a cell in the first place due to replication errors, mutations, etc.

> If that were true, it'd be great. But which is the party that supports municipal broadband for all residents as a public utility? California has a Democratic governor, Democratic legislature, and in the most populous areas Democratic local government, and yet no municipal broadband.

California politics is a clusterfuck of epic proportions because of systemic deficiencies so I'd caution against taking any conclusions from it, even though on paper one party has had near total control for decades. The major bills like budgets and taxes require a 2/3 supermajority and until independent redistricting was implemented, any sort of progress on those issues required capitulating to a small number of gerrymandered districts that tended to produce extremist politicians (relative to their demographics). I'm not talking about districts in Fresno or something, but several right in the middle of Orange County. Passing a budget in California used to be a year round job of porkbarelling and horse trading for a significant fraction of the legislature.

Once the FCC introduced net neutrality rules, no one felt it was worth the effort to revisit the rules that limited municipalities from establishing ISPs. Trump really galvanized the party in CA but now, the state is a battleground between the "neoliberal" and "progressive" factions which are both ostensibly Democrats but have fundamentally different views on the free market's place in society. Even though a lot of the "read my lips, no new taxes" types are out, there is still a fundamental philosophical difference within the party that requires compromise and politics moves slowly.

That said, (late?) last year CA won a major ruling against the FCC (remains to be seen what the Supreme Court will say) that allows it to diverge from FCC regulations so expect a lot more progress once the list of high priority items shrinks.

Generally you don't want to be around most UVC (253nm) because these wavelengths are very good at giving you cataracts, etc. So if you buy these things online, don't stay in the room when you turn them on.

There are some newer lamps (210-220nm) that don't seem to penetrate the outer layer of the epidermis (cornea or skin) and so might be OK for occupied spaces. But companies are still being very cautious about occupied uses, because this all still has yet to be proven in real life. Also, 220nm requires excimer lamps, so 253nm is way easier to get for now.
Make sure you wear longsleeve clothes and sunglasses, so you do not burn your skin or eyes!
When I bought my present laptop, it was about $200 cheaper to order the min-spec (4G RAM/500G hard disc) and add aftermarket RAM and SSD upgrades than to buy it the way I wanted from the maker.

I could imagine a firm that ordered 1000 units and did (or contracted out for) the same upgrades, now has 1000 unneeded 500-gig hard drives they can unload cheap.
The GM bailout was, in essence, a partial and temporary nationalization. The losses weren't socialized; again, the US taxpayer made a small profit off the rescue program.

You're probably using a different definition of 100% than any impossibility proof would use.

Consider some code:

---

a=malloc(1);

needfree=true;

if (hashfn(first_factor(huge_static_rsanum1))&1){needfree=false;free(a);}

if (hashfn(first_factor(huge_static_rsanum2))&1){needfree=false;free(a);}

if(needfree)free(a);

---

The decision if this has a double free or not depends on the factorizations of two huge difficult to factor constants. It either double-frees or not depending on those constants.

Surely your software cannot decide that...

What you probably mean is something like "100% on real programs rather than contrived cases". Of course, in that case, your definition of 'real programs' is the catch. :P

Sometimes things that seem like they should always work except on contrived junk like the above example actually run into limitations in practice because macros and machine code generation produce ... well ... contrived junk from time to time.
> The weight of Chrome as a browser and the more general concept of using the web as a desktop app platform are two different things.

I understand where you're coming from, but when someone says says "Electron apps are slow resource hogs", they're fundamentally referring to the underlying engine that makes those apps slow. If that engine was fast and light on resources, the complaint wouldn't exist.

Apple _does_ allow developers to use Safari Webviews within desktop apps, but by using Chromium everywhere, developers don't have to deal with cross-browser issues. Case in point: Slack video calls don't work in any web browser other than Chromium, because they don't implement WebRTC properly.
It's a very simple change, since the fundamentals of the game is still the same. It should take no more than a day to change the code and re-train the model.
As you point out, competition is better than monopoly because it provides a surplus that advantages consumers. But some things we do not want a surplus of, for example river dams. Other things can not be competitive even in principle like surface streets. Likewise as was discovered with mass transit and utilities in the last century in a world that did it's absolute best to be laissez faire.

So there are some rare cases where there must be monopolies and if you must have a monopoly, it is better to have one controlled by a democratic government than a self interested clique. At least then there is some possibility of working in the public interest on price and innovation.

That ISPs must always be a monopoly seems unlikely to me. But if it's politically impossible to break them up, then nationalizing them is still far better than the current situation.

Hacker News has incredibly good long term retention of active users (commenters/submitters). I just published a blog post on the subject (https://probdist.com/2020/03/28/the-graying-of-hacker-news-u...).

Lots of users on HN are actively contributing for years after sign up. This to me is a good sign of health. The counter point is of course, the rapid drop off in engagement after the initial month. Where a large number of users each month never return to the site.

The average comment on Hacker News last month was written by a user with 5 years of tenure on the site. Depending on your perspective you could argue this is a good or a bad thing (new users aren't contributing as much as old users, or old users are continuing to contribute!).

Is that the case? I would have assumed that restaurant kitchens are a lot better at avoiding wastage and random spoilage than home cooks. I guess there's left-overs, but you'd also have that at home.

Yes that's the plan, definitely

This far, some people have contributed translations. I think right now it's a bit complicated to get started with writing source code and running tests, and there are some refactorings and renames I started but didn't finish yet, making the source code directory structure a bit confusing.

This isn't really Chesterton's Fence. It doesn't take any soul searching or insight to answer "why was this not written in Python3 in the first place" - the answer is almost certainly that Python3 or some key libraries didn't exist.

And I ask, what's the difference? Let's try not to be pedantic here, because if they are a legal monopoly, at the end of the day they have to do what the government says, because if they don't the government could just tear the monopoly down and prop up competitors.
I believe this is the correct answer. My daughter with the masters in biology also said this was the answer.

Interesting side effect is that you can deactivate the virus by putting it in a warm dry atmosphere. The warmth encourages evaporation and drying.

Sadly I don't have any equipment for doing viral particle counts (was tempted to bid on some here: https://www.equipnet.com/auctions/ but alas, I already have way more EE test gear than I can use, no sense adding a full bio laboratory to the mix :-).

Even though I cannot prove its viability as a mitigation solution, since I have a heat gun I spray my mail with 610 degree F heat to ensure it is dry and warm (without exceeding 452 degrees of course!)

During the last 100 years Asia has seen a significant shift towards eating much more meat as their prosperity has increased, and that's very 'calorie inefficient'; if you have some chickens or a pig at a farm, then that's often a form of "recycling" various scrap; but factory farmed animals consume huge amounts of crops grown for them that have much more calories than the resulting meat/eggs/dairy/etc.

If your daily meal is mostly rice with some vegetables, then cutting down on production means famine.

If your daily meat is processed meat, then cutting down on production means slaughtering the animal stock and processing the soy/corn/etc for human consumption.

It's also good that in the northern hemisphere, where most people live, we can still choose what crops to prioritize for the 2020 harvest; there's some lock-in with specialized hardware and availability of seed stock, but in general we can adapt quite a lot still.
No, they just got their EUA submitted.
Imagine this pseudocode:

void main() {
check_goldbach(); // iterates over every integer > 2
// to see if it is an exception to
// the goldbach conjecture, and
// returns if so
use_after_free();
}

This program may be memory safe. It's possible that there is no exception to the goldbach conjecture, so check_goldbach will never halt, so use_after_free will never be called. It also may not be memory safe. If the goldbach conjecture is not true, check_goldbach will eventually return and then we'll call use_after_free.

You say your compiler accepts all programs which are memory safe, and rejects all that aren't. If so, you can use it to prove or disprove the goldbach conjecture. Since proving or disproving that conjecture comes with a one million dollar prize, it is surprising that you can solve it with your method

edit: I didn't mean to disparage WatlerBright's work, I only was taking issue with the idea that any method of static analysis can accept 100% of correct programs and reject 100% incorrect programs. This is an unavoidable consequence of the halting problem and being aware of it allows you to decide where you want the tradeoff to be. it sounds like his implementation has no false negatives at the cost of a few false positives that are rare enough for them not to really be an issue, which is still really cool

> it's hard to use more than a few megabits per person on average.

With the coming rise of streaming services(currently using 6 to 12 mbps) and other things I can regularly see each individual person using 25mbps or more with the rise of 4k. And in a house of 4. That means the house needs 100mbps real capacity. And then it needs to not be bottlenecked on the street with dozens of other houses.

And not just streaming of games. But of movies. Education. Meetings. And tons of other streaming related activities compounded on potential normal usage non streaming.

And lets not forget that my predictions are based on the short term (<5 years) time frames. Infrastructure shouldn't need replacing every 5 years, but perhaps every 10-15 years at the lowest. So in that regard I'd bump it up to say at minimum every household should be able to sustain 500mbps symmetrically during peak concurrency strain hours.

Perhaps offer up to 1 gbps to 10 gbps during non peak times and during short spikes.
Can you? The rules are unclear. Interpreted literally they would mean that the pawn could move into the square (directly in front of it) and then take one of the opponents pieces in that square.
The problem is that AT&T was pretty heavy federally regulated prior to the breakup, Carterfone, etc, and the company achieved most of this work under a regulatory framework that was an early version of what we have today for the industry - and in fact because this was prior to CLECs and RBOCs was actually more similar to a "public utility" regime (e.g. electricity) than what we have today in the telecom industry, with regulated tariffs and the gov't achieving the policy goal of ubiquitous availability through tariff rate rather than the modern surcharge arrangement. The benefits of AT&T's golden era are most attributable not to their monopoly status but to their status as a government-regulated monopoly in a fashion similar to utilities operating under franchise - one which, unlike typical franchise utilities today, was permitted by regulators to maintain a substantial R&D operation.

The system was always somewhat haphazard, for example post-WWII AT&T faced 'competition' from rural telephone cooperatives under the REA as a means of speeding up rural development. However, this was initially a bright-line geographical division of duties and REA telephone coops continued to rely on Long Lines for transit.

Of course many, many things went wrong, including the regulatory regime being a cause of AT&T's decay even prior to court action against their favor. However, it's hard to say if that would be the outcome of such a regulatory framework today (or outright nationalization), because this was the nascent stage of telecom regulation which both the government and AT&T had equal hands in "making up as they went." This was the era in which regulatory capture was more or less invented, for example, and not necessarily on purpose.

My point though is exactly that describing AT&T as "a bad monopoly" or "a good regulated private interest" are not really great arguments in that both of those things were entirely true at the same time, and the particular environment in which The Bell System formed is not one that will likely ever exist again. Newer communications utilities have broadly been shoved into the category of telephony for regulatory purposes or entirely left alone, so it's hard to foresee any future in which we will have a second "telephone era" in which a new debatably-utility emerges to be managed.

This is a nice counter example. Although it's clear the article has good intentions, it's promoting unscientific thinking with an appeal to authority ("yes, they go brrrrrr extremely quickly much of the time, and senior developers know that!"). I think there is a point to be made about how we all could benefit from quelling our outrage at decisions we initially disagree with before we've heard all the evidence, but that has nothing to do with seniority.
Linux tutorial: Passwordless SSH key-based authentication
Just to add, when I did some research on excimer lamps last week, producers are few, and the research I discovered were sometimes using the 253nm lamps, but adding filters to get to the 210-220nm range. It quite confusing, to say the least.

Edit: Indeed the article linked above is one such study:"We used a bank of three excimer lamps containing a Kr-Cl gas mixture that predominantly emits at 222 nm25,26. The exit window of each lamp was covered with a custom bandpass filter designed to remove all but the dominant emission wavelength as previously described15. Each bandpass filter (Omega Optical, Brattleboro, VT) had a center wavelength of 222 nm and a full width at half maximum (FWHM) of 25 nm and enables >20% transmission at 222 nm."

Faster is taken to mean that a lens has a larger maximum aperture, meaning more light gets in, so you can use a faster shutter speed, and hence get less motion blurring. Non-intuitively, because depth of field gets smaller as the aperture increases, faster lenses can also offer better separation of the subject from foreground / background features
