> It would have been sensible to close our borders and halt international travel 8-12 weeks ago, and begin widespread screening of suspect individuals.

Types easy; is hard.

11 weeks ago was Christmas. How many Americans were overseas on holidays for Christmas? How many Americans with Chinese relatives were in China? How many Chinese students of American universities were home on break? Is flying Boston to Seattle meaningfully different than flying Boston to Toronto? If you halt international travel and close the borders, where do the stranded travelers now live? For how long? Who pays for it? Do they lose their jobs/have to quit college? On average, nearly half of international travelers are on their way home, not out. These are real people.

> But at the time everyone said that was nuts, you want to tank our economy over some virus that's barely even outside Wuhan!?

If you set the system parameters tightly enough to prevent the virus from leaving Wuhan, I think you're basically closing travel all the time. How many people get sick and die of random, novel things? How many of those have the theoretical potential to be silently but exponentially transmissible? How can you set a system tight enough to prevent all of them while having travel and commerce?

It seems quite possible that such a tight system would be a cure that's worse than the disease. I'm not suggesting that we're doing all that we can or that we shouldn't have taken some of today's steps last week, but I am saying that I think it's completely unrealistic to think we could prevent this entirely in any sane way.
I'm not a parent, but I had a period of time, about a month, when my Mom had to teach me, because I couldn't attend school. What worked well for us was structuring and scheduling time. What didn't work well was her winging it with the curriculum.

I think if we went through that time again and I was in her shoes, I would take advantage of Khan Academy. Especially for Math, it's incredibly well structured and forces you to convince it that you've truly learned the content with built-in quizzes. It doesn't hold you back if you've got a handle on the lessons and makes sure that if you're having issues that you practice until you've really got it down.

I think the most work for you will be setting her up properly, making sure she's comfortable with the system, and being available if she's got questions that it's not quickly answering.
First, Elon Musk has an incredibly skewed version of the world.

Second, for people without educated parents (which most people who go to college can't comprehend because most people going to college had parents who also went to college), I believe a STEM education has way more value and you do in fact learn valuable things in programming, electronics, biology, chemistry, etc. from experienced people very very rapidly. It's hard finding good intro books on your own, and even harder finding people with expertise who can answer questions (if you look at a circuit and wonder what one particular capacitor is doing, it can be a rabbit hole).

Third, software, is (perhaps an unpopular opinion), not that hard to pick up. You can basically Google everything. Using Google you can even solve problems in languages you don't know. A ton of people do this. That's also part of why you see so many people programming who don't have a C.S. degree. I personally don't have a C.S. degree and feel like a lot of the projects I work on I would have been capable of learning back on middle school. You don't need years of scaffolding like you do in in physics, where each year they layer on more math and theory until they finally build up to the ability to grasp the concept you're interested in.

I think if you want to be a chemical engineer and you don't go to college, you're going to have a bad time. Same for physics. Same for electrical engineering.

For the humanities (and I'm lumping in software, because for Christ's sake, we even call them languages), I'm not really certain college provides much education. The real value is getting hired by a tech company that requires a degree (for the actual humanities... not even that I imagine).

TensorFlow Certificate Program
The growth rate in South Korea is low (1.05) because they are doing fewer tests, as they are finishing testing the sect members, as KCDC explained. IOW it does not reflect the true growth of the outbreak, but is an artifact of testing slowing down.

"so many people here debunked you"

I was criticized, but the criticism was invalid. My estimates turned out correct according to published studies (note that the high CFR >9% is not the same as the IFR which takes into account underascertainment and is lower around 0.5-1.6%):

A CFR of 18% was estimated by https://www.imperial.ac.uk/media/imperial-college/medicine/s...

A CFR of 33% was estimated by https://institutefordiseasemodeling.github.io/nCoV-public/an...

A CFR of 5.3 or 8.4% (depending on two scenarios) was estimated by https://www.mdpi.com/2077-0383/9/2/523

(These reports have been quoted by the WHO in situation report 30 (references 10, 11 and 12) and report 31: https://www.who.int/docs/default-source/coronaviruse/situati... and https://www.who.int/docs/default-source/coronaviruse/situati... )

For reference I have always claimed a WIDE range for the CFR: between 9% and 56% (see https://blog.zorinaq.com/case-fatality-ratio-ncov/) So two of the three studies support me, and the third one is slightly outside my range (with one scenario where they calculated 8.4% being close to my lower bound of 9%.)

Note that these are NOT "apocalyptic estimates", as these three published estimates and my estimate only claim to be valid for one particular case: the CFR (1) for China, (2) as of January/early February, (3) not accounting for underreporting of cases. The CFR does change significantly over time, depending on countries, and depending on the ascertainment rate. The biggest factor is underascertainment, and if we correct for this in China, we calculate a much lower fatality closer to 0.5-1.6%, we call this the Infection Fatality Ratio (IFR). See the last section in my blog post "Updates & Validation": https://blog.zorinaq.com/case-fatality-ratio-ncov/#updates--...

Perhaps you thought or assumed I was calculating the IFR, not CFR.

Let's Chat was one of the first apps we packaged for Cloudron. We used to use it as our full time chat for our customers. A great feature is that it has XMPP support (can connect using any XMPP client).

We have since moved on to Rocket.Chat. The main reason was that development stopped 2-3 years ago. Atleast back then, there was no mobile app as well

I don't mean to be glib, but isn't this a good opportunity for her to learn those skills? I wasn't a good self-learner until I was in AP Bio and the teacher was very incompetent and I had to just face down the book. That groundwork helped me so much as a freshman in college where there were lots of kids who had always had awesome, attentive teachers. Especially if you are there with her!

I love Khan Academy, and the cool thing about youtube is there are so many content creators that there will be someone your daughter thinks has a nice voice or is easy to understand or funny.
My college just basically closed and hour ago saying everything is online now after spring break. Kinda nice for my easy classes. Sucks for my harder ones though.
So you’re saying that all companies should have everyone work from home from October to February.

That’s flu season. The flu is more transmissible, has a higher fatality rate than COVID-19, and is more dangerous for the same immunocompromised demographic (young, elderly, and those with preexisting conditions).

And you think I’m being irrational.

I have mild respiratory symptoms right now (mucus in nasal cavity, post-nasal drip, fever, aches, cough) in a region where coronavirus is prevalent. There’s a good chance that I have coronavirus right now. It’s not nearly bad enough to prevent me from working, which is often the case with coronavirus because the symptoms are usually mild.

Many people with coronavirus are completely asymptomatic, recover fully and don’t even realize they had it.

You are watching the news too much, and not being appropriately skeptical of it.
> Moderating less

it means they are less likely to intervene in the discussions on them.
> but the side-channels themselves are not patched.

And might never be patched just like FLUSH+RELOAD never was. And the paper itself even points out that FLUSH+RELOAD is a more applicable attack than Load+Reload is:

> Comparison with Flush+Reload. While Flush+Reload invalidates a
cache line from the entire cache hierarchy, Load+Reload only evicts
the data for the sibling thread from the L1D. Thus, Load+Reload is
limited to cross-thread scenarios, while Flush+Reload is applicable
to cross-core scenarios too.

Collide+Probe is more interesting as it can use virtual address instead of physical address in comparison to Prime+Probe. That may get a microcode update to do a way flush on context switch as part of general Spectre mitigations (just like the branch predictors are), but it can also be handled entirely in software by adjusting how the AES implementation works as the paper also talks about.

But fundamentally what these attacks enable are super old & well known, with multiple existing mechanisms that fulfill similar roles. It's why Spectre/Meltdown never focused on the side-channel part of the attack, because it seems to just be assumed side-channels will always exist. And why the paper used existing, documented vulnerabilities to do the exploit side of their PoC, just changing the side-channel used to ex-filtrate the data.

Is there something particularly unique or severe about "Take A Way" other than techchrunch's bad reporting of it?

Sometimes I think that spirituality is something people either "get" or they don't.

For me, to consider the very fact of existence rather than non-existence, the beauty and order of it, the people around me who have somehow manifested as conscious beings from chaos... (and on and on)...

none of those things require a supreme being or intelligent creator, but the sense of awe after giving sufficient consideration is difficult to differentiate from feeling god.

I completely disagree about the Moon being more difficult. We can get to the Moon in 3 days flat. We cannot do that with Mars; to go there, humans have to spend months in space being exposed to hard radiation. With the Moon, that isn't a problem because 3 days cosmic radiation exposure isn't a big deal, as proven by our many landings on the Moon in the 60s-70s.

On top of that, the Moon has proven mineral resources which can be mined and refined on-site a lot easier than trying to do the same on Mars.

Mars is just too far away. If you're going to neglect distance, then we should just skip Mars and go straight to Alpha Centauri or some other star with a bunch of exoplanets.

I don't have kids but there's lots of Khan academy and legit youtube stuff (3blue1brown) that can be used to learn things, even if they don't get credit for the classes.

I don't know how to turn non-self-learners into self-learners though. And admittedly if I was a kid during this, I'd be playing as much video games as possible.

Hopefully most teachers have a clue and will realize this was some pretty serious circumstances and not be as harsh and do more review.
Very nice. I wonder if rr can be used as well for reverse debugging a windows DLL on Linux.
Honestly this is the last thing I'd be worrying about. A child can skip 6 months to a year of school and have almost no negative effects on their life outcomes. If they get sick and die, or their close family members do, they will definitely have negative effects on their outcomes.

There are tons of resources and communities for homeschooling on the internet. Happy to help point you to stuff if needed, but please prioritise health over potential educational slowdown.

For me the most valuable part of college was discovering how much I liked computer science. If I had picked a career when I was 17 it would not have been software engineer. Once I was in college, it was pretty simple to take a computer science class to see if I liked it, and I really did like it, even more than I had enjoyed teaching myself to program during my k-12 years. When I got bored with my original choice of major, it then seemed like a good idea to switch into computer science, and I’ve been happy with that choice ever since.

It is a shame that college is so expensive, but to me the real problem is people taking out loans to go through degree programs that don’t give you a high expected income. If you take on a lot of loans to get a CS degree from MIT, it’s probably going to be a worthwhile investment. If you take on those same loans to get a philosophy degree from Tulane, it’s a bad idea.

[EDIT] I greatly misjudged this audience. Fear is everywhere, but (at least) so is data.

WHO 10 March report: https://www.who.int/emergencies/diseases/novel-coronavirus-2...
Who is blaming here? This is a movement by the concerned for everyone. Our government is the one that has completely failed us, not just employers. Employers are expected to fail us. Every one of the issues above could be solved by a government that wanted to stop this. But no, it's a hoax to our government. Or whatever dumb shit idea they are on now. If anything, that's who the blame is falling on implicitly in this article and rightfully so. The response has been a disaster, especially in the US. After this, the only good thing that can come if it is if these scumbags get the virus themselves and it runs its course. That's the policy they are pushing anyway. So it's up to people to do what they can in the face of almost complete government inaction on the problem. What else can we do? Expect employers to fix it? It's amazing what has been done so far by then has been done without coercion. We should congratulate any steps taken voluntarily by the business sector.
I hope my kids school closes, and I'm happy to make a commitment to spending a lot of extra time helping them make up the lost progress.

My plan is to let them enjoy the time off, for the most part, and then spend the next n months on reduced entertainment in favor of extra studying.

Seems a small price to pay given how many lives will be saved by closing schools.

Edit: one concern I heard is that health care workers need schools to take care of their children. Why not start by letting anyone that can take their child home, take their child home. This would reduce the risk for the children that stay in school by a lot, which will help health care workers not get sick.

Because currently I'd risk punishment for taking my child out of school "unexcused". Which seems like some seriously backwards bs.
>As a solution to this dilemma, some advocate strong "non-moral" stances (ala "free speech") where everyone can do as they want, unrestricted

Since when is that the definition of free speech? Free speech has nothing to do with a lack of repercussions to what you say, and especially do, it's about having the right to say things, even if disagreeable, without systemic silencing or punishment from a higher authority. It doesn't mean you can't shun the crap out of people saying dumb shit though.
It's very much relevant to what we're talking about when we talk about "the API". I am skeptical that when people think about what the above reply described as the "creative work at issue", they're not thinking about the implementation at all.
True.

We keep mostly everything in-house, but team communication was the hardest part, as we wanted something that defaulted to end-to-end encryption. Surprisingly hard to beat Wire.com.

Ended up going with an XMPP server with OMEMO for encryption, and Jitsi Meet for video.

Imagine a corporate executive comes to eat at Noma but to afford that $375 meal, he had to make enough money by offshoring clothing manufacturing to Bangladesh to some worker paid $1/day working in harsh conditions. I feel it matters how that money is earned and spent. I'd rather that executive pay $2/day plus improved working conditions to that worker and instead have a more modest meal.
Yes, it's still early days for them so signing up isn't as easy as it can be. It's very usable already, though.
My plan is to report to the police, report to the company (in that order), and then get a lawyer and touch nothing else of the companies systems until the issue is resolved.

I don't give a damn what the company policy is, that shit is so corrosive that I'm not doing anything with it beyond reporting it to the authorities and then protecting myself.

The study linked in GP seems to directly refute this.

"Overall protection factors calculated per type of mask were stable over time, and did not change statistically significant with prolonged wearing."

The quote from the CDC makes no claims about efficacy, only that supply is limited and healthcare workers should be given priority.
Thank you. A lot of people think there's no big deal. The major ones to suffer are the elderly, and to walk about because you're invincible doesn't mean you're doing the world a favor. You're possibly helping the spread to elderly people.
> Well, that’s not a “true” /health endpoint, then

You cannot make such a "true" health endpoint, it's super easy to make a service that contains a paradox about what such an endpoint should do.

1 service with 2 endpoints A and B. A relies on an external service and the database, A and B both rely on the database. What to do if the external service is down bringing A down? Either your health endpoint is useless because A is down and it reports the service is fine or you just cascaded the downtime to B while there is no reason to do so. Same situation for 1 endpoint but any branch dependent on the request etc. etc.

Of course you can use a health endpoint for determining restarts, load balancers etc, but its not replacement for circuit breakers on your calls.

> but isn't this a good opportunity for her to learn those skills?

I think that’s a fair question, and I’d love to be optimistic about her ability to hunker down and build those skills. But, she has some behavioral challenges and just getting her to do homework is a nightly struggle consisting of meltdowns and arguments, so I’m not as hopeful that she’ll be able to do it. She’s a bright kid, but definitely one who -needs- the structure of a classroom to be successful.
