A personal pet peeve of mine is this newfangled stretch denim that more and more jeans seem to use. At the start of the day the fit is fine but before the end of the day the elastic has relaxed enough to where you need a belt to even keep them on at all. Add to that the magically shrinking pockets and I haven't been able to find reasonable jeans in a few years now.

Anyone looking for a co-founder?
For the last few months, I have been looking to join an early-stage tech project as a co-founder.

There have been a few false starts along the way, but I suppose that's inevitably part of the process!

I am desperate to get my teeth into a new venture, and based on my past experience I would be most suitable for a CMO/Sales Director type of role. My background is in finance so any fintech/financial start-up would be ideal, although I am definitely open to other concepts.

In terms of credentials, I have a degree from the University of Cambridge and I've got a strong financial sales background, having been a top performer at JP Morgan. I've also got an extensive network in the PE/VC world. My skillset lies in fundraising, marketing strategy and managing an end-to-end sales process. Of course, I'm more than happy to muck in wherever needed.

My current role is highly flexible, so I would be able to commit a significant amount of time to a project. I have the drive and energy to get a project off the ground! I'm currently based in London, but am happy to work remotely or relocate.

I've been amazed at the generosity of our community, so I thought I would reach out. If you're looking for a team or if you've just been sitting on an idea for a while, I'd love to hear from you.

There’s a lot of research on this in the effective charity set. See [1].

First, it is highly paternalistic to tell people what to spend money on.

Second, it takes a huge bureaucracy to manage and enforce controls. Folks still sell their food stamps.

You got a link to any tales about this happening? Would love to read about it.
This is going to last all year, and possibly much longer and most jobs can't be done from home. We're simply not set up to educate kids from home. Hence the economic hit the blog is talking about. Just because many of us have tech jobs we can do from home, doesn't mean that's a viable option for enough people for it to make a major difference.

Washing hands and not touching our faces will slow it down, not stop it. There are numerous recorded cases on transmission with no physical contact, and virus concentrations in throats and saliva are ridiculously high. This is an aerosol disease, you get it just by breathing and many of the masks out there aren't very effective against it. That's why so many health care workers are getting it. Yes we should do these things, but they won't solve the problem, only slow it down a bit and the guy writing that post knows it.
Risk analysis doesn't require complete information. I understand the risks given the current information that is being provided.

By the sound if it, your risk analysis (also based on incomplete information) has lead you to believe that I should take some measures that I am not. That does not concern me.

What do you mean exactly? If you mean locking people up in their homes for a whole year, I think this will have not only economic, but also deep social impacts.
I think the end of Soviet was bigger. This is probably the biggest thing since then.
One perspective is that we will continue on pretty much as we have been, replete with bullshit jobs, manicured lawns, and consumption to excess, because those are the only choices we know how to make.
Bullshit jobs are the job market equivalent of software bloat. They have the same issues: you can take a popular modern webapp or "desktop" app and notice that it's 80% of fat that isn't necessary for it to deliver all its value, but if you zoom in, almost every single piece of that fat can justify its existence because of other pieces. So you can't just start cutting it out piece by piece, you'd have to redesign the whole application.

Same with the job market: a lot of jobs are just fixing the damage done by other jobs, or implementing a distributed consensus algorithm through zero-sum competition. Every job is justifiable in terms of other jobs it serves, even though a whole lot of them could be pruned with no loss in value created for the society.
Anybody that wants more money. You know, the same reason that folks look for promotions: more responsibility for more money.
The anti-mask thing in the west is so upsetting, and it's more aggravating because it's the health care workers giving the horrible advice. I don't care that we don't have enough N95 masks for everybody, N95 are for preventing inhalation of virus. What we need are the disparaged "surgical" masks which are for preventing spittle flying everywhere. And they do not have to be high-tech they just have to cover the mouth. It should be mandatory to wear one out of the house. That's what China did.

> You can't get sick if you aren't exposed.

The problem isn't the short-term; the problem is the long term. Are you suggesting the entire world work from home and interact only over the internet for the rest of our lives?

One of the biggest questions in this thread is specifically what kind of immunity we can have from the virus. If catching it gives you 10-year immunity, then slowing things down might work. But what if catching it only gives you a 6-month immunity? The only way to stop it would be for the entire world to manage be SARS-CoV-2 free at the same time. Otherwise, we're looking at a situation where the thing might just keep going around the world indefinitely.
I just read this preprint: https://www.medrxiv.org/content/10.1101/2020.03.05.20031773v...

People over ~50 have a ~50% chance of not showing symptoms, under 50 is ~10%. I wonder if there was a flu/cold epidemic 50 years ago that is causing the difference?

I know that some flus have different effects depending on age group due to cohort exposure decades ago.

Though it is a preprint, so could be all sorts of sampling reasons for that outcome.

Recursive CTEs are sublime, not only for orthodox trees: combined with XMLTABLE you can even use it for recursively descending XML, normalizing it into tuples of ([array, of, tag, names], value). Then you can join on that table/view using simple and easily composable autogenerated SQL expressions instead of Xpath. And you can string-join the element path with '/' to get an Xpath expression that would get you a value from the source XML, if you need to!
I use this a lot to work with XML, even exposing it through an ORM (Django's in my case). You can do a similar recursive descend on JSON.

Not an American, but the United States and its allies - and actually probably even most of its enemies - derive enormous economic value and peace from its military control of the world, which it achieves by its navy controlling the world seas and general striking power of its armed forces [0]. The United States determines the "world order" by being the remaining world's superpower (China is only beginning to challenge the US, and mostly at a regional level).

Like it or not, the U.S. armed forces underpin the world's current economic system and its relative peace. The prosperity as a result of America's control is called Pax Americana [1].

Some might consider the U.S.' powers undesirable, but I'm not arguing in favor of the general desirability of Pax Americana here. I'm just saying: keep in mind that "keeping U.S. forces at home" and significant scaling back of the foundation of Pax Americana is not desirable from both an economic perspective (for nearly everyone) or military perspective (for probably everyone).

Don't get me wrong - Pax Americana will end at some point, but it's in the best interest for everyone that this will be a mostly gradual change. For all Americans or non-Americans, it's not desirable that the U.S. withdraws its global army for any reason, including this calamity [2].

[0]: Nukes aside, the United States army has the sheer striking force to obliterate any other armed force world wide. In a "U.S. versus the rest of the world combined" scenario, the U.S. would still have a good chance of winning.

[1]: https://en.wikipedia.org/wiki/Pax_Americana

[2]: Not the point of my post, but I don't believe this would even be a reasonable calamity for the U.S. to withdraw its armed forces for at all - outside of a small percentage of reshuffling things. Not playing down the trouble we're in at all, but we should also be making an effort to make a relative return to normalcy well within this year / within a couple of months. This is what's already being done in China.

This is talk that really drives up any resistance against sensible health support. And the worst part, the resistance is more or less justified.

You don't even know yet if the quarantine worked. We currently have data from countries without it that don't fare any worse. 2 weeks incubation period probably makes the tool worthless, but we don't have any conclusions yet.
> First, it is highly paternalistic to tell people what to spend money on.

Indeed, and that's kind-of the point: (1) you eliminate bullshit spending (on things like alcohol, tobacco, lottery) that many people are prone to do, but that they arguably shouldn't (to some extent, those products are "predatory"); (2) it provides a minimal standard (survival) yet incentivizes people to work (be productive) to increase their standard of living (e.g. to be able to buy alcohol); (3) avoids inflation, as only a very limited set of products would be affected by increased demand (in particular, not real estate, as "free" housing would only be available in government-owned real estate) that the government can plan in advance.

My prior is that "bureaucracy" can be reduced significantly with modern IT technologies.
It's worth throwing into the mix that CTEs can be an elegant solution to more than just recursive queries. I've used them to "refactor" out common parts of queries where the same subtable is referenced multiple times in the same query.

So instead of

select something from x join y on x.foo = y.foo and blah = 'cheese' where some_complicated_join_conditions ...
union
select something from x join y on x.foo = y.foo and blah <> 'cheese' where -ome_other_complicated_join_conditions

...you can have

with nerk as (
select something from x join y on x.foo = y.foo
where
hopefully you can find some common part of the complicated where clauses
)
select something from nerk where blah = 'cheese' and something
union
select something from nerk where blah <> 'cheese' and something_else

...obviously a trivial example but you get the idea. When I tested this on postgres (some time ago) this was very significantly faster for my use case.

It also helps in use cases where you want to allow user-defined filtering and ordering logic controlled by a gui. You can put your basic query as the CTE and then have all the user-controlled bits and pieces in the final select and they don't get mixed up together.

1) The employers will shut down, guaranteed. It's just a matter of whether we do it now or a few weeks from now. Just keeping everything open and running through this is not an option. The only way you can do that is to have an incredibly competent government that is on top of testing and contact tracing at all times, and that ship has long sailed. Look at the UK to see how this "keep things running and just protect the vulnerable" strategy plays out. It's already starting to break down and they'll be in lockdown in a week or two, but many more will ultimately die than they would have if they had locked down before they were forced to. It's not a question of if we lock down, but when.

2) Disagree. Again, look at Europe right now.

Covid19: Cell.com Published document having wrong date
But it needs to be based on good science. As someone in thread said, the false positive rate needs to be staggeringly low. And the false positive for Testosterone -> AntiSocial behaviour is huge - marathon runners to entrepreneurs and weight lifters.

So the idea is good - test people for something bad they will do - but the ability to test reliably for all the bad things is real low. I think we shall just stick to past crime not FutureCrime for now.

And honestly, using "bad authoritarian governments do bad things with good tools so we should not use those tools" does not make a good argument. it just means we need to double down on democracy.
Delayed, it was my takeaway from unfortunately having read far too many announcements in similar language. I could be entirely wrong, it might have been a sudden health condition.
The "herd immunity" theory seems to be the UK's approach, but it's going to fall apart quickly, I predict. They'll be in lockdown within 2 weeks.

In NYC, they just decided to shut down schools but they're providing childcare to essential personnel still, as well as meals and online education for school aged children.
I share your sentiment, this will be amazing and also a 'working together' time.

But - time - is the issue. It's medical. Stuff takes a long time to develop a test, there are real ethical rules that won't get broken I think even now.

50 years ago, there would be either some brave volunteers who would be willing to get infected or some poor souls somewhere who would be unwittingly infected to see the results. No more of this.

It's possible however the CCP may 'volunteer' some prisoners, or they may allow brave citizen volunteers. I can see that happening. (I can see brave volunteers coming from everywhere, but I don't see governments allowing such a program to go forward).
Now they work as expected. Maybe it only occurs the first time you load the page...

Sorry, I wish that were true. A non-trivial number of people under 60 year old also end up seriously ill and require critical care. In Wuhan half of all patients admitted to the ICU were age 25-49 ( https://www.thelancet.com/journals/lancet/article/PIIS0140-6... ).

For these younger people their prospects are good if they receive that care. An overloaded health system may be unable to provide that care to everyone who won't survive without it, including some younger people.

A tremendous number of working people also have preconditions which are implicated for covid19 including hypertension and obesity.

If you are a younger person and carelessly get an avoidable infection and end up in an overloaded hospital needing intensive care, your life may well be saved due to being triaged ahead of an older person with worse prospects. But in that case your life would be saved at the expense of someone else's. ... someone else who's infection might also be due to your spreading. I wouldn't be okay with that, and I hope you're not either. So I hope your glib attitude doesn't mean that you're not taking avoidable risks.

In the US there hasn't yet been clearly established ethical guidance to direct triaging like that. Your local hospital may assign ICU care first come first served... if so mortality rates there for younger people won't look so good.

> The full lockdown you are advocating for could cause significantly more devastation than it prevents.

The financial hit will be very real, but there can and will be mitigations down the line. What do you think are the chances that city, state and federal governments are all just going to let people starve in their homes? For example, the California state government has promised to keep paying teachers and school staff despite school closures. Not to mention companies, organizations and individuals. Many tech companies are continuing to pay maintenance staff despite office closures, for example.

As for the devastation that it prevents - well, many unnecessary deaths. The government might be able to pay you a portion of lost wages, give you a loan or reduce your taxes this year, but it can't bring back your loved ones if they die from the coronavirus.

> I'd be surprised if a majority of people actually did that

There are always going to be idiots and morons. But I think if cases and deaths skyrocket over the next few weeks, as is currently expected, the number of people flouting the quarantine is going to go down pretty dramatically. Not only will people become more aware of the risk, but more businesses will be closed so there's less incentive (e.g. all bars and clubs closed in several states, Starbucks is now takeout-only in some places, attractions like Disneyland closing down etc).
Why would they do that? What was their investors' reaction?
