While of course a valid question I feel like some of your assumptions might have a different impact in reality. For Germany "50% of people follow up correctly" for example seems unrealistic due to a few factors:

- The proposed centralized solution would have to rely on malice to easily identify people that did not follow up correctly since there was no means to do that in it. The only upside you would have had was more trivial means for data collection on population scale to validate random epidemiological models and validate follow up.

- 50% of people failing to follow up correctly seems like an unreasonably low number given that it's not that different from breaking quarantine with the existing process and there's few enough cases of that to still garner high profile media attention here.

- Even if 50% wrong behaviour was a correct assumption, that would be a slippery slope in most models. If you lose, say, 10% of the overall population because it's allergic to the historical and privacy implications of the system design, misbehaviour of 50% of people left using it can be pretty irrelevant.

- AFAIR adoption in Singapore, which is often used as a reason to use this model in the first place, so far has not been anywhere close to the 50% of 80% of phone users. Many people seem to suggest looking at WhatsApps growth rates for realistic adoption time frames.

Fraser et al have a few general articles and calculated through scenarios on the matter that might be interesting, maybe you get something out of those:

Many discussions w.r.t. the epidemiological impact of these trade-offs at the moment seem anecdotal because they lack proper validation. I do not think any of them so far directly address the one you are looking at here.
These conversations are always the wrong way round. Being excited about running a company is not enough - affording to do so matters. Restricting founderdom to the already wealthy or the maniacally driven seems a dumb idea.

My conjecture is that more successful companies are founded during downturns because more founders are forced into the process by circumstance.

If we want to increase the successful startups in the world, increase the number of people who can afford to do so. We are seeing paycheck protection programs across the globe - why not use some of the same cash as giant seed funds.
It sounds to me like your risk assessment is a little unbalanced.

We also have no idea what the medium and long term effects of being infected with SARS-CoV-2 are, so why are you happy to be exposed to it?

If its a the processing plant that's kind of true, even if they could run them through the automated 'harvesting' system its probably really expensive to store until an undisclosed time for it to be processed and then sent to market. At a significant loss in Market price, I imagine. So its best to take the subsidy/insured loss and restart again.

This is actually really fucking sad... I hope it encourages more people to focus on the World's broken food supply and its immense waste and do something about it. I hope we don't have to see the same thing that happened with toilet paper, and paper towels happen with our food before people get the message that we have to re-think our entire infrastructure.

> Americans eat 24M chickens per day. So 2M killed is only a fraction of the number eaten in a single day.

That's a horrible calculus, and quite frankly stereotypical of People so detached from their food system: have you taken into consideration the externalities of hatching, raising, and ultimately getting them to Market size? It's actually incredibly costly. And they were probably factory farmed, which makes it even worse given the cruel practices involved.

On a positive note: Spring is finally here, and I saw a bunch of people's Community Garden's today.

I can't say that my experience is typical, or encompassing. I'll say that I really like the way they present the APIs. but the business practices, and support are were I ran into issues.

From a work perspective we had similar issues, where the account wasn't set up on their end properly, and we were getting server errors, and issues. It took a lot longer than I would like to get it sorted out (I admit most people would say that)

I also didn't care from the developer perspective, but I think that more to my expectations of how it was sold.

If it works for you, keen, but it was enough for use to step away from the monetizing API, and just present it in a more traditional method.

This is a fantastic summary! In the United States, I believe that the Pacific Northwest and parts of the Maine coastline were also considered, but for many of the reasons above, I don't think any of those projects really achieved critical mass for wider adoption.

I'm not bullish on the future of tidal power--there may be some use case for it, but the reality of the engineering challenges associated with putting hardware in a marine tidal zone for years at a time presents serious obstacles with limited advantages over versus a wind turbine or solar array of the same capacity.

There are many small differences. Not grammatical but some off the top of my head:

* Quite means something different. In British "quite good" is similar to "particularly good". In American it's more like "OK",

* Spelling of -ing form of words ending in l. Br: travelling, Am: traveling,

* Placement of stress on multi-syllable words. It almost seems like anything British people do is the opposite in America. Br: 'adult, a'ddress, ice 'cream. Am: a'dult, 'address, 'ice cream.
"Volunteer" shouldn't be the word here.

It should be "paid".

If the pay was $10k per participant, the world would happily pay 100 people for each of 10 vaccine trials.

The people would understand the risk they were taking and be happy that the $10k was worth it for them. Countries would be happy that the payment was good value for money for finding a vaccine for their population.

"Volunteering" is in my mind ethically wrong - you are paying people in 'goodwill', which doesn't and shouldn't cover the risk satisfactorily.
The other side is that sometimes you answer the PM to actually go in a bike shop, but the company does not have the budget.

Sometimes you know that they ask a bike but will change the specifications later, so you try to prevent the mess.

No one claimed such a thing.
Do you enjoy creating stuff with the tools?

I've been interested in programming since I was a teen, but it was always the applied side - I enjoy building stuff, and the tools are just like any other tools you'd use.

I don't find the tools or methods particularly interesting, not nearly interesting enough to devote a huge part of my time to study them extensively.

And it was with that realization that I understood the following: I will never become a good computer scientist, theoretical or practical.

So my solution was simple: Do not chase, or focus jobs which require a passion or deep interest in computer science, because:

1) There are far more highly intelligent and highly passionate programmers out there, that are genuinely interested in the theory and technicalities. I will never be able to compete with those.

2) I will burn out spending my days on something which does not naturally interest me (enough to do it for min. 8 hours a day)

3) My energy should be directed at being more productive, where I can actually show good results. We have a finite amount of time to do something, so don't waste it.

All these realizations came during college. Some of my classmates would read books on compilers in their spare time, because they simply could not wait for the classes (which we had a year later).

Compilers are fascinating on a high level, but not fascinating enough for me to read whole books on them.

Furthermore - to me, proof of concept (and novelty) is more fascinating than the optimal solution.

There are lots of jobs for both types, you just need to find out what really tickles you, and follow that lead. As others have said, bridging fields ("businessman" and "developer", etc.) can be really rewarding.

Think of something that really interests you; Anything! And then try to find out how you can enhance that with development. Do it because it's fun, not because it's something you feel like forcing yourself to do.
Concentration of rainfall into artificial lakes to generate power was already done centuries ago:

Btw this same issue exhibits in python with threads. If you spawn an async computation in a thread and an uncaught error is raised, the thread disappears silently, leaving you with a callback that’s never called or a future that’s never resolved.

In the hackathon environments I've been in there isn't really an organizational hierarchy per team. Team Leader really means Team Representative; i.e. they only want one person coming up to give/receive items/documents/information, so they ask each team to pick a leader who can interact with the event staff.

> Let's check the numbers. Collective wealth of all the billionaires in the entire world is 8.6-8.7T USD [1]. Collective retirement and pension assets in just the US is 19.1T USD [2]. So it seems that commoners, relying on the retirement and pension assets, would benefit much more from a stock market recovery than the elites.

Pensions are not equity. Pensions also usually fall very high on the cap table, saving them from restructuring in bankruptcy.

> Maybe yes, maybe not? UK / France / Italy / Germany / Spain all have public healthcare and have ~320M people between them, roughly the same as the US. And yet, their COVID-19 deaths are ~100K vs ~55K for the US when both the continents had fairly similar advanced warnings. Why is this simpler (and presumably better, from your tone) system producing a far worse outcome?

That's not really how pandemics work for one; the Milan fashion show arguably killed tens of thousands of people as a superspreading event. The US healthcare system is terrible, whichever way you slice it (cost, infant mortality, outcomes).
As someone who's invested pretty heavily in real estate over the last few years (Seattle) I sometimes ponder if we are all eventually destined to a fate similar to that of Japan's. It seems to me that the US is only a superpower because we were geographically fortunate to not share contiguous borders with Europe post WWII and we've taken that for granted. Policy makers in the US don't have a long enough horizon to adequately plan for the future; and birthrates are projected to fall—it's hard to say how much, but, eventually, even below replacement rates (?).

As of late I have started to question the long-term prospect of indefinite economic growth, and what the implications of challenging the status-quo here are. I would be interested as to what people's perspectives are around the likelihood of advanced nations inevitably sharing a fate similar to Japan's.
There is not a trap in algebra that is shown in that proof: there is a mistake in that proof. They do something that is not allowed, even if it's not obvious what that was at first glance.

I don't think one can compare mistakes with thoughtful and powerful modelling.
That is indeed one of the authoritative explanations, and in a few seconds of ad-hoc search we may find at least two refutations from authoritative sources.

For example, gyroscopic-forces-as-stabiliser don't need the Schwab paper's "ton of math" to be undermined. A simple counter-rotating wheel was used empirically at Cambridge to show as much, alongside notes that gyroscopic forces are relevant to the dynamics of a loaded bicycle, but misconstrued; far from assisting to hold it upright whilst ridden, they induce instability at the beginning of a change in direction, and more so at speed, a phenomenon (counter-steering) familiar to cyclists and relied upon by motorcyclists.

Then there's a simpler observation that can be made: people have to learn to ride a bicycle. The fact it stays upright when rolling unloaded, but not when loaded, is indicative of how small the gyroscopic effect is, not how significant it is. Ergo, that argument would suggest, it is tiny shifts body position that contribute all of the stability.

And then others, proposing further explanations, etc etc ad nauseum.

I have come around to the view that in fact they don't stay upright, and they are almost always falling over, but in a many-branched configuration of the universe our observer effect sends us preferentially down the vanishingly unlikely path where they didn't, and there are an uncountably many alternatives of Me that have nothing but knee scars to show for it.

Have to agree with this. I was just reading through to try to figure out its pitch, and was struck by this (early on): "To create a value, you must merely invoke its name. This is convenient. You don’t have to gather building material for your values or pay for them. You just call for one, and whoosh, you have it"

I mean, that's totally correct, but that's paragraph 7. It's way too abstract for a beginner to understand - and usually, if a beginner is getting lost in the first few pages, they're unlikely to make progress in the book (even though they probably could in this case, by skipping ahead a bit).

It's impossible to isolate only the at risk group. That's like 30% of the population. Also, there is growing evidence that even mild cases can leave more or less permanent damage.

SARS-CoV-2 is pretty similar to other coronavirus types which humans have been exposed to for millions of years.

Vaccines on the other hand have a pretty dubious safety record. We still put mercury in many vaccines for example!

If it weren't for the massive benefits of (working) vaccines, they would undoubtedly be banned for being unsafe.
Lagrangian and Hamiltonian mechanics. That is usually presented in a very mysterious manner. Also I think most engineers do not get taught these.

More succintly: In the SIR (Susceptible, Infected, Resolved) epidimic model, r0 is the ratio of dI/dt / dR/dt. r0 < 1 means people are recovering at a rate faster than new people are getting sick.

If each new case, on average results in less
than one new case, and all cases eventually resolve (recovery or death), then it's a mathematical truth that the number of active cases must go down over time. The decrease isn't necessarily monotonic, but over a long enough time frame it's inevitable. The bursty nature of super-spreading will produce variance, but as long as these super-spreaders are accounted for in the observed r0, the variance itself doesn't change the long-term outcome.

Now, the estimated/measured r0 is just a sample/estimate of the (unknowable) "true" r0, and r0 isn't constant, but those are separate issues.
Absolutely none, unless they are car maniac.

That simply isn’t true. Other than those extremely cash-constrained choice of car is a very personal thing, as much as style of clothing.

One note: While using field number for anything is perfecrly valid SQL, this will not pass a code review if I'm the one doing the review. Reason being, it's not clear without looking at the field list what is being ordered. For extra shame do something like:

select * from foo order by 2

Order of the fields when doing "select *" may be guaranteed (I don't know) but they have been dependent on when the feild was added to the database on every system I have worked with, and sometimes patches are applied in diffrent orders on diffrent databases.
