> I always doubt extrapolation, even when it's based on good statistics.

The extrapolation is based on an extremely well tested and understood theory of epidemics. It's really as simple as: the number of people infected each day is proportional to the number of people who carry the virus, so the growth in infections is exponential. That's extremely solid logic and it's been proven time and again, so complaining about extrapolation doesn't make any sense.

> I think you're inventing things for me to have said/wanted/believed because I haven't written much that you can actually argue against.

I think your motivations are obvious. You keep dismissing the science of epidemiology, saying everything is uncertain, and you keep returning to the idea that the lockdowns will destroy the economy. A lot of people are arguing like you are.

> Maybe I'm wrong this time, and I guess we'll know in a 3-8 weeks.

At which point the US will have to go into lockdown anyways, only that the epidemic will be much worse. Better to do as doubleunplussed explains, and crush the epidemic now with a relatively short lockdown, and then partially reopen and try to contain the virus at a much lower level with widespread testing and contact tracing. China did this, and South Korea, Singapore and other countries did enough testing and contact tracing early on that they haven't had to go into lockdown.

Check any news outlet to know why, and you’re likely to also read about zoom in some article.
It's possible that there was a temporary bloom in bison and/or a few other species during the formative period of American inland exploration. The populations were hunted out so quick after this that it's hard to know how temporary this was.. if it happened at all.

But those quotes are about a lot more than one iconic species. Overall, the picture is accurate.

Yes, i was also a bit disappointed reading e.g. the reference e.g. about CSPs, it should at least link some other textbooks here. However, I admire the work being put into this. It would be great if all university teachers would make the effort to publish open access. A dream would be collaboratively maintained textbooks with strong single editors for readability and consistent style. Also there should be foundations like apache, etc that market such material and put up quality control, pay lectors where the publishers are largely failing atm.

> Owners who aren't active on Yelp may never notice this feature, and so the money is never claimed.

That's likely the whole goal this thing was set up in the first place.
They are in the same trap as traditional car manufacturers are with combustion engine cars. The profits are in the established technology, yet the writing is on the wall for the new technology. You know where the market is going eventually, but for sure you don't want to disrupt your current revenue stream until the new technology is really ready to replace the old one.

For many years, basically Nikon and Canon split up the "professional" market between each other. They already had this position with analog SLRs, and continued after the transition to digital. The reason is a mix of having very good cameras, a large lens setup, especially considering the more exotic/expensive lenses mostly used by professionals and most importantly, with the service organizations. At each olympics, they would have large service centers on-site, for repair and exchange. And also outside of these events, they have services networks which enable a professional to get the equipment serviced/exchanged with loaners in minimal time, which is a very obvious benefit. Which basically prevented other brands to make a huge inroads in the professional markets.

So their profits were driven by the established systems. They were milking this cash cow and consequently were late to the mirrorless game. Their recent offerings are nice, especially Canon has some very interesting lenses for their new mirrorless system, but even for those companies it takes a whole lot of time to have a remotely complete lens offering.

It might also be worth while to look beyond the 35mm format. In 2013 Olympus brought the OMD E-M1 to the market, which was possibly the first mirrorless camera, not only matching but in a few aspecs exceeding the performance of comparable DSLRs. This shows, how much Canon and Nikon are lagging behind.
Usually companies just hire on people at that stage to show growth, so that they’ll get more money.

Look at AirBnb - they don’t need thousands to operate their business, but they have them and they continue to hire

I changed from ynab classic to ledger cli because I’m fed up of the myriad workarounds I end up doing eg for refunds and the bucket system doesn’t really work well for my scenario. It took about half hour to Learn the basic usage and it looks really promising. It is so much more flexible. It’s like going from visual source safe to git. Looking forward to using it every day (I used to dread doing it with ynab4)

Anyhow yes cutting back a lot on expenses.
I'm really liking Zoom's responses to incidents lately. Both this and the "oops we implemented certain features by leaving a localhost webserver gaping open" fiasco fairly recently got extremely nimble responses from them, and the responses were absolutely the right thing to do. They could have hand-waved the http server away and claimed to have "secured" it, and they could have hand-waved this away as "standard practice", which, let's be frank, it almost certainly is. The fact that they understood the seriousness and swiftly yanked the features in both instances is HUGE. Kudos to them for this.

edit: some people won't want to give them any slack because they committed the offenses in the first place, but I think that's silly. Reward them for trying, because if this is the way they're going to respond to blowing it, they're one of the good guys.
I really like that you can see the doubling rate.

Nice way to bury an innocuous "iOS Advertiser ID" in the middle of the list. What "iOS Advertiser ID" means is, to a very good degree of approximation, your deanonimized identity.

Also, that just linking the SDK in your app deanonimzes the user to Facebook is very, very clear in its documentation. It's not like Zoom didn't notice until someone told them. They made a decision, and now they're changing it because they were called out.

Your points boil down to:

a) China keeps on exporting,

b) liars are caught and Trump didn't caught the Chinese regime lying,

c) The Chinese regime enforced quarantined effectively.

From these points, only the third has any relation with and impact in the outbreak of covid19 within China.

However, as the virus is reported to have an asymptomatic incubation period that can be as long as 2 to 3 weeks, and as there are reports from within China that show that covid19 can be transmitted at over 4 meters, then, as we have seen in Italy and Spain, the impact of this measure would only start to show with that much of a lag.

I admit I am not an epidemiologist, but claiming that an epidemic was just stopped on it's tracks almost instantly has little to no credibility. For that to be even remotely realistic, there needed to be zero asymptomatic carriers from one day to another.

To add insult to injury, the Chinese government reported that the only new covid19 cases experienced within China came from foreigners who imported the disease.

I'm sure the measures imposed by the Chinese regime has a profound impact on the epidemic, but none of the official reports appear to have any credibility whatsoever. A disease with a 1 to 3 week incubation period does not stop spreading or killing people from one day to the other. What does stop immediately is how you chose to report the data, specially counting the dead.

Another buggy painful non-open reimplementation of Motif, which arguably had the silliest name of any user interface toolkit in the entire universe, was Sun's and AT&T's (Unix System Laboratories) "MoOLIT", the Motif Open Look Intrinsics Toolkit, that let you switch back and forth between those two different competing looks and feels (both of which sucked in their own ways), and which was based on "OLIT", then Open Look Intrinsics Toolkit, which itself was based on the horrible X Toolkit Intrinsics (Xt), which was the root of all evil.

>MoOLIT (Motif OPEN LOOK Intrinsics Toolkit) is a graphical user interface library and application programming interface (API) created by Unix System Laboratories in an attempt to create a bridge between the two competing look-and-feels for Unix workstations at the time: OPEN LOOK and OSF Motif.

>The library provided common GUI features such as boxes, menus, lists, and buttons, but allowed users to choose which look and feel they wanted at runtime. It was a short-lived project, as the industry was moving towards Motif as the de facto GUI standard, a trend culminating in the COSE initiative in 1993.

Of course if you just wanted a laugh at the name, you could also use the X Anathema Widgets (Xaw) toolkit, but I think MoOLIT was funnier. I cracked up every time I saw some Sun marketing droid in a tie seriously talking about it.

No, not really. If(?) they want to increase adoption, they need to convince scientists to write their simulation programs in it. Realistically, that's not going to happen via HPE/Cray people having lunch meetings with individual scientists.
And my point is you can’t be prepared for months of no revenue. No consumer is going to pay the high prices needed for a business to insure itself for an extinction level event, because an alternative business won’t and will offer lower prices.

For example, a hotel owner can choose to squirrel away cash to protect the hotel and its employees for months of no income. A competing hotel will instead choose to renovate the hotel. Which hotel will customers choose to stay at?
Not anymore they don’t

The Government of Spain talked with WHO representatives(world's health organization) the 2th of February.

They(WHO) recommended them to buy covid fast tests. They did not. The Gov expected "one or two cases" so why the fuss?

So instead other countries(after having the same meeting with WHO) did it taking good quality test out of the market. Those are high accuracy.

But the Government of Spain waited for 9th of March to act because they wanted Women's manifestation to happen,the 8th of March, which for both parties in the Govertment(socialist and communist) was a priority over anything else(in order to show how progressive they were).

Waiting for so long meant the illness went out of control. It was too late for controlling it and a week later they recognized the problem.

So when they wanted to act they panicked and there was no good quality stock in the market, they bought what they could.

When the test kits came, they distributed to hospitals and the first thing they did was testing the kits, given the fact that they already have ill people and PCR machines(that give the results after hours or days).

They got an accuracy of just 30%, so the kits could not be used. It has been in any newspaper front page in Spain(El Español, El Pais[those are socialist so they are extra kind to the Gov], El Mundo).

So the order was cancelled.

If you know Spanish, it is extremely simple search:"test defectuosos". For example:

The book that provided me with the proper knowledge about investing in the stock market would be:

The Five Rules for Successful Stock Investing: Morningstar's Guide to Building Wealth and Winning in the Market

The reason I recommend this is because it teaches you how to read IFRS Financial Reports and calculate Discounted Free Cash Flow, with practical examples.

Fun fact: many people have asked me over the years what my secret to investing was, and I've always pointed them to the book, and told them it's basically just about reading and understanding each line the financial reports. It takes a lot of time to do this, and you have to do it every quarter, for all stocks you own, want to own, and keep an eye on. With time you will learn what sections to skip and it gets faster, easier. But you have to get your information from the reports themselves. To this day not even one of those people has followed my advice and read the book. I guess the thought of putting in effort scared them away as they were also asking me if they can find the reports summarized on some website and use that as their source if information, or if they can pay for some service to calculate discounted free cash flow for them. To me, having the summary and calculation alone is pointless, and it's also the fastest part of the process. What's important is to understand the reason behind the data in the report, something which the summary eliminates. I have not yet attended a Shareholders Meeting for any company, but this also helps with understanding the reasons behind the data.
