While I can't speak for people who downmodded it initially, it was probably downmodded because "sarcastic acronym guessing game" is a trope on this site that people see frequently and are getting tired of: it seems like it at first glance, especially given that there were already people implying it was a programming language by the time you sent your comment. However, APL is niche, so you probably were well-intentioned rather than playing a part in that.

It's hard on Internet forums to see if something is genuine or sarcastic, so sometimes even the nicest comments get downmodded.

That said, complaining about them only invites more. You have a higher chance of getting back to a positive score by not bringing it up, and it's against the News Guidelines to, anyway:

Please don't comment about the voting on comments. It never does any good, and it makes boring reading.

If you're consistently posting good, helpful or kind stuff to the site, it almost always outweighs downmodded comments in due time, so don't sweat it!
Here's the solution I thought of, which is pretty similar.

Start with the case definition of min.

Notice that min(a,b) <= a, min(a,b) <= b and min(a,b) in {a,b}

Let d = min(a,min(b,c)) and e = min(min(a,b),c)

Then d <= a, d <= b, d <= c and d in {a,b,c}

Same goes for e.

Since e is in {a,b,c} and d <= a, d <= b, d <= c, it must follow that d <= e. And by symmetry e <= d. So d=e.

Singapore and Taiwan are basically cities, very dense. China is a Communist country with all kinds of totalitarian policies. South Korean cases are still climbing at more than 100 a day. You can't tell precisely what the growth curve has been because there's going to be a higher bias when they ramp up testing in many countries.

At any rate, no, a town that has 50 people per square mile should not be forced to respond in the same way as some city with 50,000 people per square mile.

People are going to be working home in one way or another. I suppose that some people will be staying home to care for children. In the speech the Prime Minister said obviously some people would end up losing their jobs based on the current situation.

I didn't follow the speech very well myself because my daughter thought it was fun to throw a one person party celebrating not going to school for two weeks, my wife started yelling she couldn't understand what was being said because my daughter was being too loud (wife being Italian has sometimes difficulties following Danish language)

But anyway there are a variety of child care options in Denmark, one is thing were a person watched 3 or 4 children during the day at their house, I don't know how that is affected. I suppose it is affected the same as other services but on the other hand it might be reasonable if that was left open because I am expecting that to make the tedium somewhat manageable there will be a lot of play dates for the next couple weeks - so essentially people will have 3-4 kids at their houses they just won't be getting paid for it.

Ask HN: Engineering group to fight Covid-19 needs fee waiver from Slack
Hi,

We're organizing an engineering group to devise solutions to help against COVID-19.

We currently have 390+ people in our Slack. This includes ex-FANG, software developers and mechanical engineers. We also have PhDs, medical doctors, nurses and other clinicians.

The growth of our group was (is) extremely rapid. I expect to be quickly approaching Slack's horizon of 10,000 messages via the free plan.

Cutting off our messages will deprive us of important past insights and discussions. This will hamper our activities significantly.

Paying the standard plan's fee seems punitive in this situation. Indeed, even the non-profit rate implies monthly fees of $1,125 if we reach 500 members (we added hundreds today).

We are literally working to find ways to help frontline medical staff, who we are worried might be overwhelmed by COVID-19.

Given the time constraints, we are concentrated on products, not on funding.

Under the unique circumstances, can someone reach out to Slack corporate to ask for an exemption?

Our group is: helpfulengineering.slack.com
Bay Area, I'm wfh, my wife is wfh, all our family and friends that work for major tech companies are wfh, 85-N had no traffic at 9:30 AM this morning, we pulled our kid out of gymnastics class 2 weeks ago, we haven't been going to museums (one of which is closed, because of coronavirus), and his day care (which nominally has 12 students) was down to 7 last Friday and now 3 of those are out because of hand-foot-mouth disease. Berkeley, Stanford, and Santa Clara University have all gone remote-only and sent the students home. Stores are completely out of rice, beans, toilet paper, hand sanitizer, etc, and a bunch of people are wearing masks. I figure it's just a matter of time before we're on complete lock-down.
The first - and until now only - time I came across that 'grim little ditty' was in LeTourneau's autobiography "Mover of Men and Mountains".

Chris, glad you like it. I can relate to that feeling, which I also had as an undergrad. It was a big motivation for this work -- and I think the analogy can go even further. For example, there's a really cool lecun paper about NN training dynamics actually being a lagrangian system: http://yann.lecun.com/exdb/publis/pdf/lecun-88.pdf. Another thing I want to try is literally write down a learning problem where S (the action) is the cost function and then optimize it...
I never said they need to be treatable nor curable to be called diseases.

What I am, is wrong about it not being a disease. All these are listed as diseases: SARS-COV, MERS-COV, and nCOV. Even, also, the common flu. I never thought of that as a disease before now, since it's a viral infection. Thank you for making me learn a little more tonight.
About the same range as influenza, which is thought to be about 48 hours, but significantly longer than most common cold viruses, which remain active for only a few hours at most.

Yeah, I was thinking about symmetries <=> conservation laws because of Noether's theorem. Think of regular NN training as not having any symmetries...since they aren't baked into the model. But we can let the model learn symmetries <=> conservation laws by adding the Euler-Lagrange constraint to the forward pass of a NN.

> and is largely absent in truly free software contexts

I curious about what you mean by "truely free software"?

My impression is there's a divide in "non-proprietary" software philosophies, with Stallman out one end of the bellcurve on the "free as in speech" side, and perhaps ESR out toward the other end closer to "free as in beer". That's also close to the divide between "free software" and "open source software" in my head. There re people who are perfectly happy to give huge codebases away with almost no restrictions (for me the champion of this would be Larry Wall and the Artistic Licence/GPL dual licensing he uses for perl), while there are other people who are more politically or "freedom" motivated (like Stallman, who champions AGPL like viralality because he believes its "right" and "socially good").

Trying desperately to escape either of those outcomes are organisations (for whom I have a lot of sympathy) like MondoDB and RedisLabs, who are trying to build business models around large/expensive codebases and getting undercut by "the cloud industry" who've found legal but probably unintended holes in the licenses they released under. I don't know if RedisLabs' RASL or MongoDB's SSPL will work out long term. I kinda hope they do, because I think it'll allow a new kind of OpenSource/FreeSoftware to exist - projects the require a team of engineers getting salaries paid to do the engineering - allowing software to be created on a scale that loosely connected groups of individuals are unlikely to be able to achieve. (I know the Linux kernel is an obvious counter-example to that claim, but it's an outlier in the vast sea of open source and free software projects out there.)

(And, regardless of the implications of works like "rhetoric" and "entitlement", I can't see how _anybody_ could argue against a code/project author being able to use whatever licensing they choose - including whatever restrictions that places on people who want to use that code. Copyright law allows them to refuse you to use their code at all. Any further rights they grant you in a license are not something almost any other creative industry grants. Nobody realistically complains about the burden LucasFilm is imposing on them by the choice of what rights they grant you to use StarWars copyrighted story/theme/images/whatever - you can't show StarWars to people for free just because you're a volunteer or non profit organisation. Why should someone else's C/Python/Java/Rust code be any different?)

Finally getting around to getting a proper desk/chair/monitors really made me enjoy working from home a lot more. I don’t do it terribly often, but I really feel like it makes me more productive.

Also working with a remote colleague who doesn’t have good webcam/microphone/headphones is an absolute nightmare. I’m sure most of us have had colleagues that were frustratingly hard to communicate with remotely, and I’m sure most of us have avoided communicating with them because of it.

I've done a pretty lean amount of stocking up of supplies since I'd hope that even in a quarantine situation, there would be an opportunity once every week or two to restock. I don't have a lot of money, so going all out would ruin me since the roof over my head is just as important as food. What gives me anxiety is the fact that I've mostly worked in food service type jobs, and I've been working part-time until recently so that I could have some free time to skill up and get better work, so in a pandemic, it might become harder to find work that'll pay rent and for food. I only have enough money for one or two months of rent left, so I'm pretty desperate, trying to find work again while under all this anxiety. I have to avoid getting sick too, because I don't have healthcare and am not insured. I'll probably become homeless and die if I had to go to the hospital and got a bunch of debt I can't possibly pay. All I can do is pray and hope for the best honestly.
Just don't lick the plastic your toilet paper comes wrapped in, unpack it when you get home, and wash your hands. Same with trips to the store. This calls for being a bit more conscious of basic hygiene, not showering in disinfectant.

Is it? Don't all viruses die after a more or less fixed timespan? Do they decay like radioactive elements?
Two main things.

1) Timezones

1) Working from home takes a rather significant toll on teamwork and collaboration. Allowing people flexibility with their working hours/location is a no-brainer imo. But unless the role is specifically suited to it, you probably want people to spend most of their working hours in the office.

You get the same issues when you need people in geographically separated offices to work together. Obviously lots of companies do that already, but you still have to account for the inefficiencies it causes.

That there are results to validate that this happens on some occasions, doesn't mean it's universal or even common.
