While it's not exactly a viable skill to learn at the moment, I found learning a social partner dance to be eye opening.

(Slight aside: I started with Lindy Hop, which is typically danced to Jazz music. It has its roots in a variety of Black dances and grew out of the Savoy ballroom in Harlem starting in the late 20s. It's certainly not the only dance that teaches these skills, but I think it's a good choice.)

At the core, it's about communication and collaboration; communication and collaboration with the person you're dancing with is the essence of a partner dance. You want to make space in the dance for a balance your ideas and your partner's, and so whether you're leading (initiating movement) or following (responding), you want to share your ideas and listen to your partner's. Non-verbally. In real time. Over a lossy communication channel.

Beyond that, you're communicating and collaborating with other dancers sharing the floor. Unlike some dances, there's no macro-level choreography that keeps dancers from running into each other. You need to pay attention to your surroundings, understand how your movements are going to affect others, and adjust as the situation changes.

During classes or practice sessions, communication and collaboration with peers and instructors is also important. It's silly, but dance classes were the first time I ever really learned how to listen to and give constructive feedback in a kind and effective way.

All of that said: it's a bit like math. You'll start by counting (literally, perhaps), not with an understanding algebra or combinatorics. It won't feel revolutionary at first. You may not have any epiphanies until your instructors take of the "kid gloves" and at least reveal that "improper" fractions are just fractions and that it's a-okay to subtract a larger number from a smaller number. (And just like math, you can go as deep down any rabbit hole as you'd like. One day, after a few years of dancing and hundreds of hours of classes, I spent a full hour-long lesson exploring the complex topic of: walking forwards and backwards.)
This article is an example of why, even as an avowed lefty, I just don't like Current Affairs; this is far too many words just to say "Silicon Valley luminaries don't understand the media properties they claim to love."

My wife and I arrived in France the same day as a holiday. All the grocery stores and restaurants were closed and we had absolutely no food - we spent an hour driving/walking from place to place. Defeated and on our way back to our car to go to our rental, our savior appeared.

I was playing with it to try to model a simple regenerative system from permaculture design -- the "Three Sisters" plant guild: https://preview.tinyurl.com/ydxqmmwd

The model is really off since I can't specify units or connection weights. I was hoping the tool would be adequate enough to use as a kind of visualization or a kind of sandbox/lab to illustrate different regenerative processes. Might still work.
Seems more likely that fast charging did not work than that the phone uses >15W sustained to power the webcam?
I don’t disagree, on principle I think it is better to know your tools and know them well.

At the same time I too once had to learn my tools, and I can empathize with those that just want to quickly get to work and don’t want to memorize every single command-line option, whether this tool uses one dash or two dashes, or single letters, whole words, was it a capital “A” or a lower case “a” to do the thing I want. Personally I won’t be using fig, but I could see why someone might try it. If it helps new developers learn the command line, or helps them get to the meat of working with code without feeling hindered by what they perceive as this old archaic interface, but they want to learn this thing eventually, there’s probably some value in that.
He said: "I stopped doing CV research because I saw the impact my work was having. I loved the work but the military applications and privacy concerns eventually became impossible to ignore."

Initial good results on CV doesn't mean that you realize all the ways it'll start to be used and the implications thereof.

User 29athrowaway mentions in another comment that they use Sympy through Sagemath, so they probably could answer your question best. It sounds like Sympy is a subset of what Sage offers, but I'm not familiar enough with either tool to know.

> What a house of cards the U.S. economy is.

No, actually pre-corona it was the strongest in world history because the US actually makes things, unlike the European "sick men" welfare economies.

My concerns are:

1) the societal rot that has set in, that will ultimately weaken the US and has already resulted in a populist President. Health insurance and education costs are an assault on the middle class and small business owners.

2) the monetary life support provided to Wall Street since 2008 with no effort at unwinding federal support for private industry since then. We've doubled-down during corona.
Overall yes it wasn't clear to most commentators, but there were actually plenty of people who predicted pretty much exactly what would happen and why, Horace Dediu for example.

When the iPhone came out I knew Apple would own the future, I could feel it in my bones not only because their software technology was so ridiculously far in advance of everyone else, but because none of their competitors except Google even seemed aware what was happening or why and Google at the time wasn't even in the game yet. A lot of my friends thought I was going a bit crazy, I was so sure Apple was going to utterly own the future. I was entranced by the early iPhones, they felt like something out of Star Trek except even better. Maybe part of it was I always hated mobile phones, they were so clunky and ugly and the tech was so primitive. The iPhone felt like an advanced graphics workstation in an era of teletype terminals.

The problem was I was recently married, had two kids and we'd just bought our first house at a huge financial stretch, and had no spare savings whasoever. We were practically living hand to mouth. When we did have spare savings 6 or 7 years later I did consider buying some APPL, but I thought most of the opportunity cost had already passed and Android seemed to be catching up at last. Dumb.

But honestly, imagine what today would be like if Andy Rubin hadn't immediately ditched their plans for Android to be a BlackBerry clone and switched tracks to cloning the iPhone. Microsoft genuinely didn't get it. They took 3 years to even realise there was a problem.

Sorry, ranting, but thinking about this really triggered memories from that era.
I had overlooked the potential impact of internet censorship. It seems like it would be very hard to take a graduate-level class without access to resources like Google Scholar.

In Sweden, yes.

If you have tested positive within 30 days before dying, that is counted as a COVID-19 death.
I only went through the first ten or so questions so far (will do more later cuz it's neat stuff) but yeah, all if this was covered in a single semester of automata in my undergraduate. Although, maybe a graduate entrance exam isn't supposed to test much more than what you learn during the course of undergraduate classes.
The definitions are different and always have been.

There is a long history of reasoned debate about which measure is better and what the differences are, and there are many worthwhile articles on the subject.

Phylogenetic analysis showed that in most countries there were multiple seeding events before the infections were discovered. In short, it wasn't just one sick person.
The main problem (and again, I shouldn’t be doing a value assessment of Quilette sticking to my original point, but you’ve asked) is that Quilette “scholars” seemed to have started from 1700s race research, jumped to Jim Crow-era race research, and seemingly skipped everything before and after The Bell Curve(1994) research that does not suit their argument of genetic determinism.

To my initial point, value-arguments aside(I’m certainly not going to convince you), does an African developer want to seek out Quilette to publish?

HN downvotes me because Claire Lehmann is a Paul Graham darling, but the only thing "Libertarian" about Quilette is the fact they bypass violation of the NAP with the argument the black people are either (A)not people or (B)"less than" people.

I don't really buy this. You're framing this as if people don't use this notation because they are self taught. But I've worked in companies full of fresh out of college people and we didn't use this notation when working on projects. And when working on group projects in college, we didn't use it either when discussing possible solutions. We used pseudocode.

Beyond that, I think you're selling an ideal here in these other professions that doesn't necessarily exist. There certainly is some vocabulary overlap but a huge problem in e.g. medicine is practicing doctors not being able to understand the science behind medicines and procedures that biased 3rd parties are recommending they offer to patients.
Parent poster was not talking about people who are merely being asked "to support their side in the current moment"; their concern was specifically wrt. the slogan/hashtag "Black Lives Matter", which is associated with a radical Marxist organization. One can care about Black lives and even demonstrate that they care without endorsing a harmful slogan.

> I think I'd actually feel a lot better about things if I were witnessing an argument about fringe political beliefs coming to the fore, rather than finding out how many people I know are overtly or covertly racist.

That makes sense, but it's also sensible to ask whether hijacking a much-needed conversation about race and police brutality to push fringe, Marxist-inspired political views helps people and institutions become less racist. It's not even clear that 'Black Lives Matter', as an overtly organized and led social movement, is doing all that much to meaningfully improve Black lives.

As others have mentioned, socat acts more like a router between different socket types/protocols but it doesn't change the behaviour of the program in question.

So for example if you have a service listening to TCP port 1234, you could do something like this:

socat UNIX-LISTEN:foo.sock TCP:localhost:1234

Now the service will still listen to port 1234 and you now have another socket that redirects to the other. This not only comes with a bit of overhead, but port 1234 is still reachable.

While using packet filtering on that port might lower the attack surface a bit, this won't prevent other (possibly compromised) services/users on the system to access port 1234.

Sure you could also filter based on uid, but IMHO it's better if that port isn't accessible in the first place.
I could also indicate that the excess deaths is due to the lockdown or from how a country are handling the Covid-19 pandemic, i.e. not handling other cases in time.

Elon Musk Ends Up Making over $50M from His SEC Settlement
I'm a developer and I think it'd be useful. I'm semi-fluent (conversational?) when it comes to CLIs, and this looks like a great way to recall stuff for less frequently used commands or edge cases.

Two reasons why I would download this but not a full on GUIs for things:

1. There's a long tail of CLI tools I use just rarely enough that I can't justify downloading a whole application for something. I just don't need to run awk or sed that often. But if you aggregate "all terminal commands I need to Google usage for", then that adds up just enough to download a helper.

2. There are contexts in which I can't use a GUI. For example, sometimes I need to SSH into a headless server and update a Git repo or do something with sed and awk on a giant pile of logs that I don't want to transfer to my local machine.
What some friends remember most about their grad student days in the States is having the police called on them because they were walking around their neighbourhood. "We have a car. It's in our garage." was their defence when grilled by the responding officer.

Setup Map on an Android Application in smart way
Part of it is because he’s painting now whereas before he was mostly drawing. You just can’t get as much detail that way.

But even so, yes, this looks amateurish. Which is probably due to he fact that he no longer paints / draws for a living and because he’s just starting out in this medium.
Classification as fear mongering should depend on the frequency and harm caused.

I tend to think that the reporting on these complications focuses on the fact that it can happen, without sufficient detail on how often, and how bad it is, and how often it happens in the absence of Covid-19. This information is necessary to inform people of how concerned they should be. Without it, readers are left up to their imagination.

If covid has a 0.X% infection fatality rate, and a 0.0X% chance of a less severe complication, how much more concerned should the public be?
I think the alternative boils down to "neglect my child so I have more free time" which isn't really a sensible option.
They are preventable, vaccine on the horizon.
In industry, yes. I had the impression this article was aimed at academia and research in AI.
I think SARS was what motivated these countries to be prepared and it paid off.

On the other side of the world it was complete lack of leadership and even dismantling of the preparation efforts that were taken earlier.
And comparing statistics from different countries is difficult under the best of times due to differences in definition, reporting quality, etc.

For something as polarized as COVID? Good luck.
I feel that so many of these articles on Sweden fail to mention the reason for Sweden's strategy and often say it due to another reason. The reason that the Swedish government has given for the strategy is that they think that people can follow the restrictions long term. It's not to save the economy or to create heard immunity (which I have heard from many people.) I think it's too early to judge Sweden's strategy as presumably the intent is that things will be better down the line.

On a more personal note, I live in Sweden and I am not a Swedish citizen and I can say that things aren't "Business as usual here" and plenty is being done to stop the spread of the COVID 19. I can't say I 100% agree with the policy but I also don't think it's the huge mistake people make it out to be.

I have linked below an explanation for the strategy by one of Sweden's top epidemiologist and the one that's often credited as the architect of Sweden's strategy.

> in any case, I think that free software movements are a sociological anomaly, I wonder if there is any academic research into this from an antropological or an historical economics viewpoint.

I don't have the proper background to make a strong case about this, but I feel like middle ages guilds would be closer to the open-source model than to the current "trades secrets" one, wouldn't it?

Likewise, I don't see farmers of ye olde times keeping their crop-growing tricks to themselves as secrets and so on.

Furthermore, we've known about many indigenous cultures where "the tribe" is regarded as more important than the individual, meaning that sociologically they should be more aligned with the open-source model than the capitalistic one, shouldn't it?

Again, I'm not an expert in the area, but it seems to me that our current society is more "historically anomalous" at the commoner level than any more socially-conscious one would be (i.e.: common people has leaned to greed/individuality these days than almost always in the past).
That proposed title subtly promotes the "covid isn't that bad" theory by hiding some of its worse outcomes. I can't do anything about the proximal cause, I can however protect against the distal.
Just trying to provoke an answer with a little humour ...

It is obvious to anyone that one of the primary uses of computer vision is to watch other humans at scale. This cannot be surprising to anyone in the field yet now there are ethical concerns mixed with politics through the roof.

Maybe we can be more precise about this?

The work here is a technical achievement but there are some weird comments here which I think has something to do with the author being Chinese.
And even if it was the best course of action, that doesn’t mean there won’t be unintended consequences.
I can see the power in a future OS interface that really combined the terminal and GUI in a powerful way. Maybe this is a good start to thinking about that.
Let's look at British Columbia, Canada where we have managed to stabilize at ~10 cases a day. How long before we get the same number of deaths with our population of 5 million people. Hmm, 5 million divided by 10 divided by 365 is 1369 years. Even if we consider 10 cases for every one detected case that's ~137 years! Longer than a human life span. Ignoring things like improved treatment options, vaccines, and other things that are going to change in our understanding.

So I think this proves the argument wrong.

If you consider the other costs you're avoiding, long term issues for sick people, the cost of treating all these people in hospital, the potential for people to get sick with this multiple times (we don't know if you get any immunity by getting sick) then it's even clearer.

But medicine once you get to application of drugs rather than anatomy (setting bones, surgery) crosses over into another domain: chemistry, and at it's lowest level chemistry in turn is physics. Doctors need to know how to diagnose an issue (which often involves other disciplines within medicine for instance radiology), and then what particular medication or procedure to prescribe to solve the problem. The implementation details of that medication are not that important until you get to side effects, akin to how a programmer might select a library to perform a certain function.

Flu vaccine reduces risk of death. Coronavirus has no vaccine yet. I do think we take the flu too lightly. Urgent care and hospitals definitely need to be more risk averse even after this pandemic is over, and I hope we learn that lesson in this pandemic.
