Actually, we tried both exhaustive search and sufficient search (where we had a soft-deadline and accepted the best solution reached within the deadline). Even with this dark launch found queries in our stream that had unacceptable delays. We were in contact with the team through the development process, so we at least had some reason for belief that we were using best practices. And you're right that ultimately the CP solver wasn't the right tool for this job -- simplifying the problem and giving up some capabilities was the solution. We had hoped that a general solution would be feasible, as that would allow expressing some things efficiently which we couldn't in our existing setup. But it was not to be.

Yes, the Handle procedures are associated with their objects by means of function pointers (for e.g. C++-style OOP), but also inside themselves they implement big ol' IF,THEN,ELSE chains to do (Smalltalk/Actor-style OOP) messaging handling.
I've been wondering if there's a correlation between authoritarianism and lead pollution. Like how leaded gasoline seems to correlate with violence and crime. Then that cohort (boomers, more or less) became the largest voting block and changed politics.

In my grossly oversimplified worldview, authoritarianism is shorthand for heightened fear response and lowered empathy.
My suggestion is that the on-site people should have alerts about hardware events. Unless it's a failing sensor, there shouldn't be any false positives - if a machine is exceeding its recommended operating temperature it's still not good and warrants an investigation even if it isn't yet causing problems (in fact the point of these alerts is to catch and fix these issues before they cause any user-facing issues).
Yes, my point is that this is being ignored by the government as it lends its ears to behavioural economists.

We have no good way to measure the CoV spread beforehand so being prudent and proactive with the response is better than to delay introducing additional measures until it is absolutely necessary because you won't know it until it hits you and then it's too late.
I do wonder how long the general public, many of whom are now sitting at home on their ass all day, are going to continue doing so and let themselves, their families and friends, and the rest of the nation starve, instead of taking a risk and volunteering to help make and deliver food.

The divisive, isolationist, "only me and my immediate friends and family matter" attitude that is so prevalent in America starkly shows its corrosive effects in crisis.
Ibuprofen is an anti-inflammation drug, which means it weakens somewhat your immune system (which is responsible for the inflammation in the first place). It makes sort of sense that taking such medication while infected with a virus for which there is no treatment can be dangerous.

In related news, there have been cases of "severe" forms of Covid-19 among young people with no antecedents, all of them having taken ibuprofen.

Please don't take ibuprofen.

How long does any particular region of vents last? If these active geological phenomena are anything like volcanos, some of them might well last for millions of years, which is plenty long for biological evolution.

I'm not sure if this is the case, but it seems to me it could be the case that some vent regions are isolated from others, such that life adapted to one cannot find it's way to another. This is certainly the case with many species of troglofauna (cave dwelling creatures.) Destroying one group of ocean vents may wipe out numerous species of life that exist nowhere else.

The biggest reason to keep TOTP in a password manager is that people are more likely to use it, which is a much better security stance than having a better system that no one wants to use.

For example, if you use 1Password to fill in your creds on a website with a stored OTP setting, 1Password puts your OTP on the clipboard so that you can just paste it into the next page without taking any other steps. This has driven up adoption immensely at my work.
I work with csv files a lot. I have a short awk script which truncates/pads each column to a fixed width which I can specify at runtime. It also repeats the top column (headers) every 20 rows in a different ANSI color. I pipe the output to less -SR for interactive use so I can scan delimited data in a scrollable grid, with all columns aligned and labeled.

I understand there's vim plugins for this, but, ehh.
> If anything, I would expect higher prices would discourage hoarding

This is false. We are seeing artificial shortages due to hoarding that has already occurred. Higher prices would encourage hoarders to profit from their hoarding. I think it’s fair for people to stock up on a few weeks to a month’s worth of food and toiletries to avoid unnecessary trips to the store until they need to stock back up again, but if a hoarder bought way more than they’ll ever need and they can’t profit by selling their wares at higher prices, then they might as well just give them to those in need, or be left with a lifetime supply of toilet paper occupying their guest room.

The stores will restock. This is not a shortage due to production deficits. This is just people taking everything off the shelves as soon as they are restocked. These stores are just going to keep restocking and the panic buying will subside.
The actual title of this article is, "Are patients with hypertension and diabetes mellitus at increased risk for COVID-19 infection?"

The relevant portion about ibuprofen, lightly edited to make it more readable, is:

> Coronaviruses bind to their target cells through ACE2. The expression of ACE2 is substantially increased in patients with diabetes, who are treated with ACE inhibitors and ARBs. Hypertension is also treated with ACE inhibitors and ARBs, which results in an upregulation of ACE2. ACE2 can also be increased by thiazolidinediones and ibuprofen. These data suggest that ACE2 expression is increased in diabetes and treatment with ACE inhibitors and ARBs increases ACE2 expression. Consequently, the increased expression of ACE2 would facilitate infection with COVID-19. We therefore hypothesise that diabetes and hypertension treatment with ACE2-stimulating drugs increases the risk of developing severe and fatal COVID-19.

More broadly, they're saying that many of the medical notes of patients who died mentioned that the patients also had diabetes or hypertension, and they're wondering if the correlation is about the treatment for those conditions and not about the conditions themselves.

It's not clear to me whether they're implying that anyone who takes ibuprofen (e.g. for a headache or even for a COVID-19 fever) will have more ACE2 and therefore be more susceptible to severe and fatal COVID-19, or if that effect only happens in the context of treatment for diabetes and hypertension. I can see how you can read it in the first way, but it feels like they would have titled it clearer if that were what they were actually saying.

In particular, there is plenty of advice for people with mild COVID-19 cases to do the normal things they'd do to take care of a flu at home, including take ibuprofen. If that's a bad idea, I feel like they would have said that more loudly.

(For instance - does it matter whether you've got more ACE2 if you're already infected and trying to keep the symptoms under control?)

EDIT: Thanks to 'FeteCommuniste in another comment for linking this Twitter thread https://twitter.com/angie_rasmussen/status/12389469379166822... which points out that this is an un-peer-reviewed hypothesis.

> A: Yes, two patients in the U.S. tested positive for MERS-CoV infection, both in May 2014.

The hospitals (nurses at them) that I've heard from say they don't have the masks on hand and they have received no training for how to deal with something like this on this scale. In fact they are being told things contrary to their training like having them wipe down the disposable shield of a CAPR [2] with bleach to re-use it (they are supposed to be single use).

They have limited (10 in the case of the CAPR shields in one hospital) because it's only required for specific diseases that they see few to no cases of per year. They don't have stockpiles of n95 masks because they could alway just order more if they needed them (same with CAPR). They are having to use the CAPR's temporarily because you need to pass a n95 mask fit test [3] (to insure nothing can get in) but the nurses haven't done that. At one hospital they just so happened (dumb luck) to have someone working that day that knew how to administer it and so they have been rushing to have nurses complete it.

> I can’t imagine that this calculation is meaningful in any way. The errors don’t average out here; the curve we’re modeling is exponential, tiny errors in assumptions can lead to roughly 100% error in the output. Isn’t there a word for when a lot of math and complexity and specific numbers with names imbue an article with some extra sense of being true or having authority?

The official term for the issue is False Precision [1], though I usually just say “false sense of precision”.

If someone does actually carry through and calculate margins of error due to their varied assumptions, it lets the reader decide. Unfortunately, I’ve rarely seen folks treat errors as anything other than independent, unless they’re actually building a model that they evaluate with a Monte Carlo method (e.g., system temperature and cpu busy-ness are correlated when machine failure rates).

Except California has price gouging laws that make it illegal to increase prices more than 10% in an emergency situation. Good luck doubling or tripling wages with that 10% margin.

59 million people in Hubei province. 67,000 confirmed cases, 3000 deaths.

Lets assume all cases were identified. 59 million did not get the disease. It kills 4%.

A vaccine will take at least 18 months to develop. Can China keep Hubei locked down at the current rate for 18 months? Could we do that in the West?

We run into this for customer support (www.assembled.com) and one of the things we've learned is that the ability to solve the fully constrained problem in the real world is not quite enough, at least for our customers.

Quite often, people are looking for the right set of constraints to apply so they're kind of running a meta problem on top of the NSP. How many back-to-back shifts should I allow? Should people's shifts always start at the same time? Can I give some people regular 9-5 schedules? All of the above questions will decrease the strict optimality of the solution, but increase the happiness and long term retention of your workforce. Thus, the question really become, how much do each of these cost in terms of optimality and what are the tradeoffs.

We've found that developing a very fast heuristic algorithm for the NSP allows people to iterate quickly on these types of questions (even though it's not quite as optimal as a SAT solver). We use a greedy algorithm with a heuristic that is relatively specific to our problem domain to ensure that we have a reasonable combination of speed and optimality.
I’ll go out on a limb here and say that this sounds “Dr Strangelove” level bad. Like, phenomenally cavalier.

They need to release the data and assumptions they’re basing their simulations on, because this will affect the entire world, not just the UK.

The current numbers have COVID-19 at something like 20x more deadly [than the flu] for people under 50. It’s not nothing. At scale, that’s a lot of people dying. Those numbers are also a reflection of the treatment being done in all the other areas of the world right now. Does their model adjust for an increased mortality rate that would surely occur in an overwhelmed medical system? Are they assuming a nearly perfectly executed quarantine of the elderly?

They need to share their data and assumptions.

> In related news, there have been cases of "severe" forms of Covid-19 among young people with no antecedents, all of them having taken ibuprofen.

I'm not sure what you're trying to say here - are you claiming that all young people with severe cases of COVID-19 (including, for instance, 33-year-old Wenliang Li) took ibuprofen?

Or simply that there exists a small group of people such that all people in that group took ibuprofen, and there are also other young people with severe cases who did not?

Given that standard advice for young people (who are expected not to have severe cases) is to take fever-reducing medication like ibuprofen, I feel like we need a lot more information here before we can turn this correlation into causation.

There were zero cases in Italy 6 weeks ago.

Lets assume China and South Korea manage to stop every single person from having it - even people with mild symptoms, and get 99% of people crossing the borders into quarantine for 14 days.

They then lift the lockdown.

Aren't they simply back to the stage Italy was in 6 weeks ago? A couple of weeks later one or two of the 1% of people avoiding quarantine. They can try the "contain" phase again, but eventually that will fail, so after 4 months from loosening the reigns, they're back into major outbreaks and back with lockdown. Expect that to happen many times over the next 18 months.

Even with a vaccine we haven't managed to eliminate polio or measles, and almost everyone is immune to them and doesn't carry it, we won't be able to eliminate covid either.
But this isn't even the real headline. The real headline is "Are patients with hypertension and diabetes mellitus at increased risk for COVID-19 infection?"

Second rules out cause though. If you have A=>B and B=>A as possibilities, and you can rule one of them out with a very simple question, that's a good way to start.

I'm the original/lead developer of ardour, a cross-platform digital audio workstation, written in C++.

Our dependency stack contains about 80 3rd party libraries. We have a custom build script to download and compile these libraries.

58 of those libraries can be built using common steps that assume the use of autotools. The remainder are riddled with special case instructions.

I wish I could say that I was more optimistic about efforts like those described in the linked-to content, but I frankly am utterly pessimistic that "dds" or any similar system will ever handle the build requirements of a project like Ardour.

Note also that a large chunk of those libraries are not even written in C++, so their authors and maintainers would not consider them part of any C++ ecosystem should one ever emerge.
I'm wondering if some of the downside of anti-inflammatories is that they often lower fevers. A fever is the body's natural response to infection, to raise the rate of chemical reactions and make more immune cells:

https://www.sciencedaily.com/releases/2011/11/111101130200.h...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4869589/

I also think that this is part of the mechanism that makes zinc effective against viruses as a catalyst.

Generally, I think that it's good to keep fevers down for non-lethal infections like the common cold, especially for children. Just beware that aspirin may cause Reye's syndrome in the young:

https://www.healthline.com/health/headache-reyes-syndrome

But for serious infections like Covid-19, maybe it would be better to maintain a relatively safe temperature of say 101-102 F (38-39 C)? I'm honestly curious to know what doctors think of this.
