As I understand it, the difference from flu is that it's much, much more contagious. 10 pct hospitalized is very different if there are 100,000 cases vs 100,000,000. There are roughly a million hospital beds in the U.S., I dont know how many ventilators but a lot less. The healthcare system could be easily buried if we can't "flatten the curve". The same number of people, roughly, will get sick, just not as many at a time.
I think those ruminative philosophical talks can be intellectually stimulating but you need some real world practical experience working in tech. IT can be a broad term, there's helping people with their computers, hardware issues, configuring companies web pages or intranet, software engineering, these are all very different things, you need to clarify what you are getting at. I'm guessing software engineering.

Lisp is a great language, however there are far more software jobs using other languages. I suggest you work on some fun toy problems and try programming in a more commercially employable and approachable language, I suggest python. You can do everything on line. There are these self-contained browser programming environments. After you get started you can install software on your own computer, I wouldn't start with that. A quick web search found this page - https://www.learnpython.org/. But there are tons of them. Find one of those, work on something interesting to you and then see if you are interested. There are lots of interesting things in the computer science world, but since you have years of yearning, I suggest narrowing your focus to something that is more direct, assuming employment is your goal. As a beginner with no recent school experience as a dev or employment (apparently), it will be hard to find that first job, but once you have one your resume will get you considered for the next. Good luck!
I also wonder if encouraging this form of meetings could be viewed as discriminatory if you have employees who have physical disabilities that might make walking unpleasant or slow.

My understanding is that young people are at lower risk of severe symptoms, but they can still get infected and transmit the virus to others.
in terms of risk it's not an unreasonable thing to assume, waiting is more risk.

There is literature on respiratory infections in dormitories:

I teach graduate and undergraduate courses in the humanities at a university in Japan. We don't know yet what will happen with our new school year, which begins in April, but some of the faculty have already started to experiment with online tools to see what might be feasible.

Each semester I teach a graduate seminar that typically has about a dozen students, all sitting around one table in a cramped room. The format is ideal for discussions, as we can all see and hear each other and read each other's expressions and gestures in real time. (Needless to say, the format also seems ideal for spreading coronavirus infections.)

If I had to, I could teach the seminar using Google Meet or a similar service, though it would be difficult to replicate the spontaneous interaction of the in-person discussions. However, there might be advantages to online discussions, such as allowing people more time to compose their thoughts before speaking or writing. I won't know until we try.

My bigger concern is with two freshman courses that I am scheduled to teach starting in April. While graduate students are already socialized to university life, first-year undergraduates are being exposed to it for the first time. I worry how well newly admitted students would be able to adjust to the university if they are still sitting at home by themselves in front of their computers. (Most students at our university live at home or in their own apartments, not in dormitories, so the housing issue is not so serious.)

Other commenters here have noted the difficulty of moving lab classes online. To those I would add foreign-language classes that emphasize spoken interaction and practicums in subjects like nursing, medicine, physical education, etc.
Nobody manufactures used cars. They all start as new and they all have a finite lifetime as a result of wear and collisions.

A used electric car is better for the environment than a used ICE car, but the only way to get used electric cars is to make new electric cars.

It depends on where you live. My understanding is that in most places in the US you have to have both people's consent. However, in New York, for example, due to laws put in place to make it easier to fight organized crime, recording doesn't require the other person's consent.

Is there any blogs or interviews with people who have the virus and aren’t over 60 years old?

When we launched https://glideapps.com, we expected to use PWA as a temporary platform as we tested our product theories. The advances Google, Microsoft, and even Apple have made in PWA support since then totally surprised us, and our web-based apps have taken us further than we ever imagined. I've always been skeptical of non-native but I can't argue with what I see every day.
Food itself is meant to be safe. So as long as you wash your hands right before eating this doesn't seem any less safe.

If you stand up a python json rpc server (using whatever libraries are mentioned at the top of the article) it will be nowhere near the untuned numbers. I’d guess more than an order of magnitude off, based on experience with similar python stacks.

If you tune and use a performance oriented language (on a big multicore machine), you can probably get about 100x better than the untuned not-python throughputs. So, for http hello world, 1000 untuned python servers ~= one beefy server.
Marketing on Pinterest
A few years ago I worked for a company which was sending many hundreds of thousands of Twilio SMS messages and observed a lot of undefined behavior at scale. Sometimes messages would be delivered twice, sometimes messages would take hours (or days!) to send, and sometimes messages weren't sent at all (even though we were charged for them). I received all sorts of "explanations" most of them naming various intermediaries in the pipe using opaque black lists and undisclosed rate limiting.

Is the SMS backbone in the US reliable during peak traffic (such as at a large sporting event or in an emergency situation) such that I can trust it as a single-point-of-failure for critical applications, and how does the US SMS backbone compare to that of other countries with less investment in their IT infrastructure? Finally, how vulnerable is SMS messaging to snooping by authoritarian governments compared to other forms of authentication?

FWIW this is definitely a project i'll be following, from the perspective that authentication can often be a "bounce-point" for new users of consumer applications and superior authentication strategies can translate directly to $ales.
Maybe there's some ML/AI that can be applied to help, if the data were available publicly
Although this company could certainly provide rate limiting services, a perfectly valid answer to this might be "you build the rate limiting yourself". You understand what a valid use case looks like better than this third party does.

I think maybe part of the problem across the board is a tendency to use analogous thinking to 'raise the stakes' of relatively minor matters by comparing them to very serious matters. It's important to keep ourselves grounded and remember that we're discussing programs, not pogroms.
While plot in the current political climate is obviously a stretch, it’s an allusion to the annexation of Crimea. Overall, given constrains, it’s well executed.
It's worth mentioning that cargo culting and arbitrary decision-making aren't necessarily bad from the perspective of the Chesteron's Fence thought experiment.

It may not matter if people who left the fence alone even knew why they were doing it. What matters is whether the fence serves an important purpose. Of course, there is wisdom in finding out exact reasons, but sometimes the reasons aren't consciously chosen. There are such things as emergent and unintended benefits.
Haha not sad. It's hard to have an informed opinion, better to acknowledge it.

I am impressed with the XBee series 3 modules that I've bought. Digi is 100% behind the product. The documentation is great. The engineering is of the 'we're go to the Moon' era not 'move fast and break things' crap the perforates startups. I'm very impressed so they're a tough entrenched to beat.
That's true in practice with current radios, but it was a beautiful discovery in 2006 that it's not true in theory! In a world where radios are perfect and nodes cooperate to do decentralized beamforming, the capacity-per-node of a random mesh network scales as the number of nodes increases. See Ozgur, Leveque, and Tse, "Hierarchical Cooperation Achieves Optimal Capacity Scaling in Ad Hoc Networks," IEEE Trans. Info. Theory (2007) (https://arxiv.org/abs/cs/0611070).

(Also worth reading: Tim Shepard's Ph.D. dissertation from 1995 (http://groups.csail.mit.edu/ana/Publications/PubPDFs/Timothy...), which predates a lot of the "information theory" interest in this subject.)
Would that kind of language/dialog be tolerated if it was directed at other people present or on the team? Or towards stakeholders? Of course not.

The ESR comment clearly directed at an OSI "person present" who also was a stakeholder, FYI.
And this was obvious from the start. Tesla is in a unique situation where they basically build their own battery factories and get exclusive access to batteries. ICE manufacturers don't want to become battery manufacturers themselves but they also don't want to commit money to bootstrap a third party manufacturer (that may end up supplying their competition) if they can get away with selling ICE cars.
Ask HN: Is there an algorithm to generate coherent color palettes?
Designers come up with a collection of colors that are aesthetically pleasing.

Colors on electronic screens are just numbers. So by first principles, designers are in fact picking some numbers from an infinite set.

This selection process is certainly not random. It's common knowledge that blue works well with red on flags.

My question is: can a computer come up with a color palette (ie hex codes) that will work well together?

Is there any literature around this topic?

PS: I'm working on a side project that needs to generate color palettes and I have no clue about it.

Thanks

Yeah, obviously it's not an easy decision, but my definition of "won't even notice" is that it even if it's a $20M write off, it's like 0.06% of their 2019 net income. For a lot of independent events (like SWSX) canceling the event means losing most of their operating budget.
Consider what the media stands to gain from all this frenzy. You think they want people calm or reading/watching/consooming as much as possible all hours of the day?

Use your judgement
Flu typically doesn't need breathing apparatus. I think in 1-2 months we will know much more and will have better stats. Until then I think treating it as R0 > 2 and mortality rate of 1-2% would serve us well.
How would that help with this issue, which is specific to the processor itself?
I'm not in the market for a Tesla and I will probably never be even though I am very interested in EVs.
Not really. Some people like to stock up on bottled water and toilet paper so they can play zombie apocalypse, but taking appropriate safety measures to prevent it from spreading is a sufficient response.
Just like a big percentage of Japanese cars destined to the US market are assembled in the US or Mexico, Tesla will probably build their highest volume cars in the EU the moment it makes sense. They've broken ground for a large factory in Berlin already.

OK fair enough.

One advantage that drew my interest in SQRL (besides being free and open) is that it avoids having any secrets being kept by any service, making any potential leaks a non-issue.
I'm not following this logic. That $20B created a million vehicles (and counting) that release much less pollution over their lifetime than $20B spent making ICE vehicles.
are you implying it was engineered for this?
Apart from the fact that, within the context of the other words of my post, your first sentence is plain not true, I'm not sure I (to paraphrase Babbage badly) I understand the level of confusion that is required to come to your conclusion.

When combating a large-scale crisis like this, you need well-coordinated action. The very basic thing you can not have is every Dick and Harry making their own decisions and improvising on what is the best course of action, each from their own (limited) knowledge of facts and circumstances. More concretely, you can not have every random call center employee decide for themselves whether or not to follow the explicit instructions they are given. That would devolve into chaos in a matter of hours. So no, nothing that happened here is 'negligent' or 'reckless'. ('harmful to human lives', we'll know in a few months or years, but it's a different matter all together). You need central control, and you suggesting that people should just make up their own course of action (call center employees, no less - the people tasked with the dissemination of the very protocol itself) is so far beyond my frame of understanding that I do not think we can have a meaningful discussion on this.

(and you 'recalling reading some paper on epidemiology' and basing your (seemingly very strongly held) opinion on everyone winging it on that, just confirms this view on how to manage large scale hazard events)
I wrote a similar one to correct people's misspellings of the word 'definite'. It got banned quickly, but it's clear why. Unsolicited @ mentions are against the API terms. Was fun while it lasted but definitely deserved the ban.
The cruise ship isn’t a good test of anything because the healthcare the infected received wasn’t under strain and resource limited like it will be when widespread infection hits. I get why people cling to its example out of optimism, but look at the reality in Italy now for a better example of what things will look like further out, and what most people will face.
Life Care Center in Washington had 120 residents a week ago. Now 19 of them are dead.[1] Does that sound like "just the flu?"

There's plenty of evidence that this is much worse than the flu. R0 is >2, compared to 1.3. Mortality rate seems to be at least 5x higher. And those are low bounds. And this is all adding to the regular load on hospitals. It has observably overloaded hospital capacity in China and Italy.

> We should go further and invent the conservatism of the archive. When we contemplate changing the rules of society, the archive needs to contain more than just the justification of the new rules, analogous to the purpose of the fence. The defeated opposition must also have their place in the records.

> Write down your rules. Write down why you have chosen them. Write down what your critics say will go wrong. Write down what your critics say we should do instead

This is a lot less valuable than you're implying. The problem with this approach is that practices succeed or fail independently of why people believe they succeed or fail. The archive can only tell you what someone thought the benefit of a practice was; it can't tell you what the benefit actually was.

An open source maintainer is not your boss. If your work on an open source project is not being accepted, you can just fork the project and effortlessly escape any "hostility", while still taking full credit for your coding. The proposed Persona Non Grata clause actively creates a full-blown "hostile work environment" problem where none existed before (by purposely obstructing the "freedom to fork" aspect of FLOSS development), so if you're right it's Ehmke who is doing what you describe, not ESR.
And inversely, if you're well, fewer trips out to common spaces where exposure is possible.
FWIW I don't record meetings, I record notes when I am walking by myself. That said California is a two party consent state so if I were to record a 1:1 I would insure that I had the other person's ok to do so (recorded :-))
Is that really what second order thinking is? I wanted to see some examples of successfully thinking through consequences of consequences, but the examples seem to be only going one level deep. For example in the CFO in a startup example, I would think that old employees jumping ship when snacks are made paid is a first-order impact - just that the CFO did not think through all possible connotations. I would think second order thinking would be thinking about what is the impact of the savings itself, and realizing that it might not be worth it.
Sure, but the dining halls are being closed for the same reason as the dorms. If not for the coronavirus then neither closure would be happening.

In other words, it's not like the dining halls are being closed and then as a consequence the dorms are being closed for lack of food options.

Yep, most JPEG images might not look different, however the OS allows RGB values outside the regular range for any color specific API. When working directly with colors, the wide color support is still relevant (and for me, led to the bug I described - devices prior to iPhone 7 didn’t exhibit the bug, because the OS clamped RGB values to the standard range.).
What I don't understand is what the "untuned" case here is. You could stand up a Python JSON RPC server and simply "not tune it". That would be "untuned code". Presumably that isn't what's being described.

Is this some C code written by the author? Is it Apache? Something else? Is the point just how much faster native code is than Python?
That's the plan here. HSAs align a lot of interests between insurers, consumers, and doctors. Unfortunately Uncle Sam is left out so I don't expect a lot of support over the upcoming years.

Yup, it's the same reason why most people now see the Japanese internment as unjust. They just know we won the war and fail to connect the dots that the internment was potentially critical to winning the war.
Probably, the better way to view these measures by various organizations is in terms of liability.

1. There's various low-hanging performance fruit that hasn't been picked.

2. Python has several different ways to do concurrency (because they evolved over ~25 years) that shouldn't be mixed but it's very easy to accidentally mix them.

3. Binary RPC (e.g. gRPC or Thrift) is more efficient than REST.
Language / framework and DB choice does matter for performance. A lot.

https://www.techempower.com/benchmarks/#section=data-r18&hw=...

As you can see, the fastest Python implementation is just 11% of the top solution in Rust.

And your key/value store choice matters a lot. Redis is well known, but it's much slower than Tarantool or LMDB. Which is slower than RocksDB or Aerospike (though take this claim with a grain of salt, they can perform differently under different loads (writes, reads, updates, deletes) and different number of concurrent requests).
The tragic part is there were probably employees pushing for change but management must've smothered them like a dying patient with a pillow.
