I think that given the magnitude of the adopted measures it is understandable that they were decided in the course of a few days. Stopping a country of 60 million is no joke. I'm not sure about the panic, but it seems hard to avoid when you tell a whole coutry to not leave their homes. We were also in uncharted territory, in the west: other countries can watch and follow what Italy has done. And yet they seem too slow in taking action. The US hasn't even started testing people.
Fact 1: There are always bugs or unforeseen events in software.

Fact 2: When there is an unforeseen event, the developer did not consider what to do.

Fact 3: Developers often deal with other people's buggy code.

It's clear that exceptions aren't the perfect solution to anything, but given these 3 facts, exceptions are around to stay.

Plenty of lower income lawyers out there, but yeah. Like anything, the best candidates get the best jobs. You’re not going to a top firm if you graduate at the bottom of your class and went to an average school, unless you have some other magical quality or connection.
The basic calculation is: 1-1/R0

R0 is around 3.

So 1-1/3=0.67 => 67% of population will be infected.

That is the situation if we don't do effective measures on a population level.

Edit: I am unable to math, fixed.
Can someone ELI5 where all the costs are to flip from black to red like this? Are they not including things like salaries to calculate gross margin? It seems those are the COGS of an IP based business, not raw materials

GAAP gross profit was $157.5 million, or 86.6% gross margin, compared to $105.7 million, or 86.6% gross margin, in the fourth quarter of fiscal year 2019. Non-GAAP gross profit was $160.6 million, or 88.3% gross margin, compared to $106.3 million, or 87.1% gross margin, in the fourth quarter of fiscal year 2019.

GAAP operating loss was $91.2 million, or 50.1% of total revenue, compared to a $43.4 million loss in the fourth quarter of fiscal year 2019, or 35.6% of total revenue. Non-GAAP operating loss was $23.1 million, or 12.7% of total revenue
kx also have a version for ARM (available here https://kx.com/download ). Note this is the non-commercial version, not sure if they have a commercial version for ARM.

Their frequent mention of IoT is (I think) more to do with storing data from IoT devices, not directly on the devices themselves.

Shakti (Arthur Whitney's current company) has also mentioned a wider support of architectures I think, but at the moment their k (k9) is in pretty early stages, still x86/64 only I think.

There are various other open source implementations of k (posted elsewhere on this HN thread), some of them might also support other architectures (although they won't have the performance of Kx/Shakti versions).
That would be a terrible idea at best and a recipe for disaster at worst. The idea right now is to reduce the rate of transmission, so the health system can cope with the demand, as 20% of the cases will require hospitalization.

Throwing this kind of parties would do the opposite, saturating the health system and thus, increasing the death rate.

Sorry, but it's the worst idea I've heard in a while, by far.
SOC2 doesn’t judge which SSO you use (or even if you use SSO).

> if ... accurate, that Trump intentionally did not want more testing, to keep the reported number of infected low, to ... increase his re-election chances. ... it's not politics. It's unethical and immoral...

I'm no fan of Trump, but that's loading on too much. It's just bad instincts and leadership, no one could know how this would unfold.
Eh, preprints have become incredibly common over the last few years and, in my experience, most scientists seem to take them almost or as seriously as the "final" peer-reviewed journal article.

Don't forget that the traditional pre-publication peer review is more of a sanity check than a sacrament. All that happens is that ~3 people spend ~5-10 hours each reading the paper, thinking about it, and writing up their comments. This is often enough to flag major issues, especially in the interpretation of the data, but it's certainly possible for subtle errors to slip through.
> That sentiment of "a real Python programmer" speaks to a mentality of in-group superiority,

I don't agree with you at all. By the context, the term "a real python programmer" clearly meanys a developer who actually has used Python in the past in a remotely significant way, at least slightly above the level of an intro to Python tutorial. Knowing the syntax is not knowing how to use a language.

It isn't elitist or classist to see red flags in a C++ programmer who fails to use smart pointers or doesn't understand the difference between pass by value and pass by reference. If someone passing himself as an experienced C++ programmer fails to allocate memory with new and just throws mallocs around, the reaction would be the same.

I'm fairly certain finding the vaccine is really quite easy to develop and has been done by multiple companies small and large already. The main issue is to do the clinical trials and get it approved and mass produced in a timely fashion.

These trials and the validation can take about a year.

The next sentence was worse:

There's a better solution: use open-source cli tools that do just that!

1. 520 Python checks? Use `wemake-python-styleguide` (wrapper around flake8) that has bigger amount of checks: https://github.com/wemake-services/wemake-python-styleguide There's also `pylint` with a set of awesome checks as well.

2. Type checking? Use `mypy`: it just a single command!

3. Autofixing? Use `black` / `autopep8` / `autoflake` and you can use `pybetter` to have the same ~15 auto-fix rules. But, it is completely free and open-source

I don't like this whole idea of such tools (both technically and ethically):

- Why would anyone want to send all their codebase to 3rd party? We used to call it a security breach back in the days

- On moral side, this (and similar) projects look like thin wrappers around open-source tools but with a monetisation model. How much do these companies contribute back to the original authors of pylint, mypy, flake8? Ones who created and maintained them for years. I will be happy to be wrong here

No mainstream physicist really objects to decoherence - it is obvious. But just decoherence doesn’t give you single outcomes - it gives you many worlds.

And people do debate how to derive our single world experience from many worlds. It can’t be done without more assumptions.

Many in this field do accept it, but say the other worlds are not real (QBism, dBB).

But that position is philosophically weak, so those against many worlds still look for alternatives.

It hasn't been just two men. Damn near half the politically interested country do not care what Trump does.

"You know what else they say about my people? The polls, they say I have the most loyal people. Did you ever see that? Where I could stand in the middle of Fifth Avenue and shoot somebody and I wouldn’t lose any voters, okay? It’s like incredible,"

It's the party, it's the newly installed judges, it's his family and associates.

Trump won't topple the Republic. He will test every weakness of it and teach future iterations how to do it better. He is teaching adversaries how to manipulate and control this country better.

Rome didn't fall in a day. Neither the republic nor the empire.

The two men are figureheads for a whole system, some known, some not, which is dealing a serious blow to the institutions of the republic; damage that won't just be undone by a "good" election.

We need to elect a president that actively wants to limit the power of the presidency (not of the government, of the office and branch) and a Congress which is more interested in the individual representitives and their views than the parties. We have to have a voting republic that values these things instead of the mixture of team sport and religious crusade which American politics has become.
Not to mention a better baseline immunity within the population, and more preparedness as a whole.

Testing kit shortages, lack of information, no vaccine, etc. are all a function of how little time we've had to respond. If we can buy 3 months, that's a lot of bonus time to prepare.
For me as a developer and CTO, it's still a huge pain figuring out how to properly configure and scale AWS, Azure, or GCP. In-depth reports on "How to configure your AWS EC2 for max. performance" would be great, one report each for a specific use case, e.g. realtime chat app, basic apache webserver, nodejs web app, ... If you think about it, there are only a handful common use cases.
> the term "a real python programmer" clearly meanys a developer who actually has used Python in the past in a remotely significant way

As a "real python programmer" that is trying to manage a conversion from Python 2 to 3, I can confirm that there is no superiority complex. We feel whipped and beaten, forced to convert a code-base that has been deemed "legacy" in exchange for a few nice string manipulation features that we don't really need.

A "real python programmer" in 2020 is an abandoned class.

You mean Congress and anyone reverses it / figures it out.
The gold standard would be: I just click "add new server", and you start off with some basic, general compute server. The server then itself figures out the optimal network, EC2, Storage, ... and all the other parameters by itself (just by knowing what general use case you're aiming for [see above])
There are also some cases of people getting the illness again so it seems like there is little benefit to this idea.
Just look at how many people from other other countries got infected in northern Italy a few weeks ago. Italy had diagnosed a few hundred cases, yet suddenly hundreds and hundreds of people who were in the area and have returned home now have it in other countries. It's clearly far more highly prevalent than testing suggests.

Thanks for the quick reply.

In the article I referenced, the company says they use a novel plant based method which allows mass production, and expect phase three clinical trials to be completed by November.

The company, Medicago, is not on the list you provided. It also seems to be a Pentagon funded biotech company so trying to understand how credible this news may be (I'm sure there are many unscrupulous companies trying to claim a miracle cure at this point!)

It is astonishing that even on a side like hn people are not capable of understanding some simple maths.

10% of infected persons need intensive care including ventilation.

The US has 100k intensive care unit beds. About 90% are already occupied.

If only 10% get infected at the same time, the health system will be totally overwhelmed.

If 30% get it at the same time, millions will be left dying.

I am missing the words to describe the stupidity of a Corona party.
PostgreSQL wire protocol has a concept extended query which splits out query execution into 3 steps, parse, bind and execute. https://www.postgresql.org/docs/devel/protocol-flow.html#PRO... If you send one parse message and multiple bind and execute messages you can insert multiple rows parsing the statement only once. Currently psycopg2 doesn't support that, which is the first thing the blog post was talking about.

If working in the confines of psycopg2, you could do something like insert .. on conflict .. select * from unnest(%s) rows(a int, b text, ...); and pass in an array of row types. Parsing a huge array is cheaper than parsing a huge SQL statement.
Covid-19 vs. Open Source Development
At Shakti they are working on that; there are quite a lot experimentations with embedded boards in the (small) community of people who work on the core. They might provide ARM compiles (they already work) so it should work on quite a range of devices; however you do need somewhat more memory than for instance I am used to work with (MCU's with 23 kb usable memory); I think it needs at least a few 100kb to do anything and (probably) a few meg to do actual work with it. It'll improve.
Based on the points above, I am still not convinced this is significantly better than existing players, but I could be wrong. Additionally, some of the problems you've mentioned in other comments have already been solved by your competitors.

Do you think the fact that you're a late entrant into this market makes it difficult and/or challenging for your team? Why have your customers chosen you over other platforms?

Biden did not interfere with any investigation.

- His son was never accused nor suspected of any crimes

- The prosecutor he asked to be removed had been in his position for 18 months and had made no progress pursuing burisma nor would he like his predecessor he was in bed with monied interests in the Ukraine. He as corrupt and everyone knew it.

If his son was guilty of anything beyond trading on his father's rep shaking up the status qou would be to his sons disadvantage.

- The president asked for a public announcement of an investigation on TV purely and only to solicit help to smear a political rival. There is no other narrative that makes any sense whatsoever.
That'd be amazing. However servers don't see all use cases, especially ones that will break it, until it gets broken. This is why anomaly detection also only goes so far.

Worse, you're changing the equation constantly when you work on your features.

Finally when these things do happen, the server will protect itself in the interim. When it does that, things will be broken.

Hey man, no argument from me; I appreciate the need to study deadly diseases in the flesh. I just wonder if they could maybe locate their biosafety-level-4 lab somewhere other than in a metropolis of eleven million people. You know, just in case.

For what it's worth, one of the names on that paper is Shi Zhengli, one of the lab’s top researchers who is now defending the lab to the media:

[Shi Zhengli] said on her social media account that she “guaranteed with her own life” that the outbreak had nothing to do with the lab but was a “nemesis for the barbaric habits and lifestyle of some people – like eating wild game including bats.”

https://asiatimes.com/2020/02/coronavirus-lab-leakage-rumors...

EDIT:

As I noted in my other comment, these researchers didn't actually create a new coronavirus, but rather a much simpler and safer virus purpose-built to test some receptor-binding structures.
You can’t get any information from that because the main interpretations all make the same predictions from an outside perspective, which is what you’ll expect to see.

Besides to put a person in a superposition may require a machine as large as the universe, so you get issues with the speed of light.

The only way to test MWI is multiverse immortality - many worlds means you should expect to always have some future experience - there is no real death.

FWIW. My wife is Japanese and I lived in Japan through Fukushima as well.

A lot of people seem to think that Japan must somehow have a higher infection rate but I haven't seen any evidence that this is true.

For all the docileness of the mainstream media and the lame-duck politics it is a free and democratic society. The government couldn't hide a mass outbreak of corona virus anymore than it has been able to hide any other scandal. In fact almost certainly less given the levels of public interest.

The Ministry of Health and Welfare publishes updated statistics daily (https://www.mhlw.go.jp/stf/seisakunitsuite/bunya/0000164708_... -- in Japanese). looking at the current stats published there's not really any obvious problems. They're seeing about an 8% positive rate on corona virus tests and 1.8% of those with confirmed infections have died. This is well below the rates seen in Iran, Italy, America and China suggesting they've been relatively thorough in catching infections, although less so than South Korea.

In truth the Japanese healthcare system is probably the best in the world at providing population level care. Since long before Corona virus standards of hygiene have been very high. Masks and hand sanitizer bottles have been a common site for a long time, hand washing and gargling is heavily encouraged, and direct contact (hand shakes, hugs, back pats .etc.) is very restrained.

Whats more for all the criticism it copped the Japanese government has been pretty decisive in responding to corona virus. It's shut down schools. It's shut down public spaces (museums, libraries .etc.). It's discouraged crowds. It's encourage working from home. It's restricted travel from hot spots. It's isolated those with infections. Also most age homes seem to have gone into lock down weeks ago.

In theory this might be true. But with the current corporate debt bubble not all will survive this recession.
Care to explain why there was lack of leadership in 2009 when 57 million Americans got infected with H1N1? Or why Ebola response was also botched? There seems to be a long history of incompetence here. You can't fix incompetence by giving the incompetent more money or keeping them around.
Unless you are about to accuse Trump of shooting someone on Fifth Avenue it isn't really that worrying. The man has been known to say things that he doesn't actually believe.

Ask HN: What is good circuit designer and emulator for me?
Hi,
I'm planning to build a 8 bit CPU using TTL logic gates. I'm having difficulty finding a circuit designer and emulator. Emulation is critical for me since I need to debug before implementing the circuit to lower the costs because logic gates are really expensive in my accessible markets.

Logisim was promising before but I had hard time using it.

Are there any good circuit emulators for my use case?
Thanks.
