"Calculus" by Tom Apostol has lots and lots of simple physics applications.

I cant think of any obvious applications of calculus to the average non-technical person's daily life. If that's what you mean, you're going to have a bad time, as I think it's a misconception of what math is supposed to be for.

Sure, some bodies don't, some bodies do. There is nothing natural about the body ability to eat whenever it feels like and as much it feels like and not get fat. A lot of cats and dogs will get fat if we give them unlimited access to food as well and others won't (well, at least some cats won't). Humans are not special snowflakes.
Until these things work well with phones, I can't buy into them. I have a U2F key that I use as a shortcut for accessing things like Google's services. But I am sticking to always using either Google Authenticator or SMS, if it's available, as a primary option. When I am looking at a website in bed on my phone, and my YubiKey is in my laptop downstairs, I can't say I am happy that I can't access my account.

I think the form factor for these things is just wrong. I don't always have my keys with me. I do have my phone much more frequently. Even more frequently I have things like my Pebble. Maybe some kind of NFC interface with a wrist watch would be a better alternative.

Google supports the U2F standard for logins through Chrome. It's a theoretically standardized browser API, but it's only been implemented in Chrome so far.
Then again, the author worked on the topic, doesn't try to hide the fact that this is a personal project and provides open source, auditable code. As much as I understand that crypto is somehow special and cannot be done "almost right", this is just someone bringing something to the table no matter what. Maybe it will somehow encourage others to try to understand the concepts behind cryptography, which will foster exchange and debate, which is always good.
>Musk is talking about a direct brain to computer interface. Video/typing/etc cannot be compared, even remotely. You're missing Musk's point if you argue down that path.

While I think its clear the direct to brain interfaces are not even remotely similar to video/typing, I don't think that is relevant to the GP's point vis a vis:

>We really struggle to get computers to understand what we mean.

What I mean is that even if we had the rich interaction of a direct brain to compute interface available, it might not be worth much of anything for programming computers, where the problem is about clarifying concepts rather than expressing information. Having said that, one has to imagine that these kind of interfaces could do a lot for artistic projects that can make direct use of information in the brain.

Here's some background for the strike: https://en.wikipedia.org/wiki/Professional_Air_Traffic_Contr...

The Professional Air Traffic Controllers Organization or PATCO was a United States trade union that operated from 1968 until its decertification in 1981 following an illegal strike that was broken by the Reagan Administration. According to labor historian Joseph A. McCartin, the 1981 strike and defeat of PATCO was "one of the most important events in late twentieth century U.S. labor history".

Also you have to remember Ukraine only became a country in 1991. Before that is was USSR. For someone like Putin, Ukraine is still a rouge state to be brought back in the fold. Like Taiwan/China. I feel the world has moved on from USSR boarders but I also understand how someone who lived longer may see things differently. Its not that long ago.

If Canada were to allow China to start building military bases and anti-ICBM defense sites on the Canada/US border, there'd be regime change on Parliament Hill within the week.

Every empire needs aligned, friendly, or at least, neutral buffer states on their borders - and will violently defend incursions into their buffer zones. Observe the shitshow over Cuba - sixty years of sanctions, terrorism, assassination attempts, an invasion, and a nuclear crisis later, the United States still hasn't forgiven it.

The United States was ready to bathe the entire world in nuclear fire - because a neighbouring country entered into a military alliance with the USSR. Let that sink in... And then consider what expanding NATO into Eastern Europe, US support of Georgia, regime change in Syria looks like from the Russian point of view.

> Unless you think the Russian government is filled with incompetent idiots I don't think they're incapable of understanding American resistance to the idea of war over Latvia regardless of what the President says.

If one thinks that "they understand what we think anyway" then the whole idea of foreign poilicy, military posture, diplomacy is moot - it's just various mind readers knowing what everyone thinks :)

Obviously the russians have a good idea what America think and vice versa. Deterrence is having that tiny doubt in the back of their minds that "maybe, just maybe, Article V is really invoked if we do X".

The only thing that is dangerous is removing that doubt - which really can only be done via a clumsy statement from one party bound by it. So long as it's guessing about the status of Article V in a Baltic crisis it's fine. All a US administration has to do is keep everyone guessing.

Supporting or undermining it by unpaid distribution of its disgusting output material? If he was directly supporting it, he would be already convicted based on tracing the payments, I guess.

From the studies I can Google, the jury still seems to be out on the dominated trans fat in animal sources, vaccenic acid, and related compounds known as conjugated linoleic acids. The later group of trans fats actually might be beneficial to human health: some studies have linked it to anti-cancer properties (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4964663/) and fat loss (http://ajcn.nutrition.org/content/85/5/1203.long), although as indicated studies are very preliminary at the moment, so you really can't conclude anything definitely about this.

I can even Google papers such as this -- https://www.ncbi.nlm.nih.gov/pubmed/19935865 -- that seem to say vaccenic acid might not be that bad, which is contrary to the link you provided. Again -- this is more not to say vaccenic acid is good, and more that I believe the science is inconclusive right now.

Elaidic acid (the "bad" partially hydrogenated vegetable oil trans fat) is present in natural sources as well, but in much smaller quantities.

Small amounts of trans fats are pretty much found in any animal product, so it is difficult to avoid trans fats entirely unless you become completely vegan. Personally... my guess is that a small amount of animal based trans fat is not going to be a big deal overall, so a little butter is fine. The studies are most damning at the moment over partially hydrogenated vegetable oil.
"You keep plaintext archives and drafts of your messages, because that's a fundamental feature of email clients going back 3 decades."

No it's not, you don't have to keep it at all or in plaintext and it's irrelevant for new clients supporting encryption, their UX have to be redesigned anyway. So it's a UX issue at most.

"Your peer accidentally forgot to encrypt a response and quoted your own plaintext back to you."

Again, just a UX issue. Although all messaging apps actually have incentives to provide a UX that lets them spy on most people's communications or be open to add that possibility some time in the future.

"that has your security one surreptitious Javascript injection on an XHR call away from complete collapse"

This is a problem of centralization that you are trying to ignore and none of those messaging apps can solve it. Any centralized system is one tiny change away from a complete collapse. It can also be shut down by the state just to force people to use plaintext or backdoored alternatives. The problem is even bigger than it looks, even if you make a completely decentralized protocol there will still be incentives to centralize as much of it as possible to make money and still leave a strategic possibility to spy on everyone also for money. Makes sense?
100% correct! Does the Cuban Missile Crisis ring any bells??
It is a threat to our system, and the fallout of our system is a threat to our life, but the AI aren't intentionally threatening us; our lack of foresight and stubborn desire to live under a wage earning system will eventually hurt us because our efficiency is always going to lag behind a digital intelligence. This isn't Skynet, this is the logical conclusion of capitalism.

Psychology in Design. Principles Helping to Understand Users
>If data science just becomes a code word for brogramming your way through a set of black-box ML algorithms, then I will welcome the inevitable crash of data science.

A fundamental challenge I see here is how bottom-heavy data science feels now. There are tons of people out there trying to "get into data science" from other fields, but the number of people with substantive domain knowledge, strong programming skills, and the math background to be able to understand the ML black boxes is quite small relative to the number of people calling themselves data scientists. In other words, real insight definitely is (or should be) the goal, but real insight is really hard, and scikit-learn is so easy.

My hope is that this improves over the next 5-10 years - the more mature data science becomes as a discipline/career, the better the education will be and the more experienced people there will be. There is a risk in the mean time, though, that a flood of relatively inexperienced people causes a collapse in expectations for data science, making businesses less eager to hire them in the future.

You can actually store the key you use for SSH authentication on the Yubikey [1]. The main advantage is that the key never leaves the device, so even if your computer is compromised, your key is still safe.

Same thing goes for anything else involving GPG keys - email, signing git commits or tags, software releases, etc.

I don't personally use it for OTP. I do use it for services that support U2F (which is different from OTP, and has the main advantage of being immune to phishing).

> Constitutional rights protect citizens from our government regardless of their physical location.

Well, the constitution is the rules and limits that apply to the US Government mainly (for the benefit of not only the US citizens).

However the Constitution is pretty much defined as the Law of the Land (Article VI https://en.wikisource.org/wiki/Constitution_of_the_United_St... )

And if the case is as you describe then it seems it's a case for a federal prosecutor to make in Court.
What's the benefit of decentralization? Not being snarky, I just don't really see it. What does a decentralized PGP email have that I don't have with my Signal Messenger?

Also, given how PGP works I fail to see how you can claim that you can achieve comparable client design/ease of use/UX to Signal.

At the very least it appears evident to me that the problem is much much harder than Signal (and it should be, Signal was designed from the ground up with UX in mind, and made several important trade offs for it).
Augmented reality is a big idea like the smartphone, Apple CEO says
In your story I can find a similarity with a problem I had: you were put on hold because of a "key customer" while I haven't enough "bargaining power" to have my customer to stop the former website from receiving new orders and new registrations (it is an ecommerce website) for a time long enough to have the site correctly migrated without further pressure. In both cases there were an added difficulty because of being too much "compassionate" with the customer needs.
My university uses gitlab and it feels very slow. Pushing changes takes 5-10x longer than anywhere else, even from the university network. (compared to github or even my server sitting at home on a normal home DSL connection)
No, maintenance to existing infrastructure. This distinction is important. Most people think of new roads, bridges, dams, railroads when they think infrastructure. Politicians love to attach their names to such things so they get funded first. Often at the expense of keeping existing infrastructure.

You see this all over, roads that people use in bad shape while new "roads to nowhere" are being built.
That doesn't change the fact that you may still need to use it in a friend's computer, or at an internet café.

Do everyone a favor. In the future, when such projects come up for vote, assume the politicians are lying to you and, most importantly, they are as incompetent as a truck driver attempting open heart surgery. That's a good start. Then do some research and see if in the last fifty years they have ever completed any project on time, on budget and without major problems.

Armed with that reality, please don't vote to give incompetent liars the ability to create another mess and screw us all, again.

If there are such places, I would suspect that their existence relies on careful management of endless september and being selective in terms of allowing participation...or another way of looking at it, is that they are unlike the internet in terms of cultural norms by being unlike the internet in terms of promotion. E.g. the best way to facilitate scholarly discussion is by restricting discussion to scholars.

All of which is speculation.

Do they fidget? Under lab conditions people who seem to do no exercise but consume lots of calories without putting on weight are found to never actually keep still—they fidget and their legs vibrate.

Obese people usually display the opposite: they sit very still.

I often wonder how much obesity is a result of telling young children to keep still and stop fidgeting.

> No, it's not. It's the only widely available, decentralized system, with which you can send to anyone, if you know the address.

They have to be email users to have an address. Granted, it's so widespread that even signing up for one of the other messengers often requires an email address, so even the non-email users have email addresses.

But I still think email is going to go the way of usenet, non-internet phone calls and the dodo. Perhaps it's too hard fixing email, compared to just moving to something else. Email is obviously hard to solve since it hasn't been solved already.
Yes, it's bad because it's a crime.

Even though the term is not used in it, possibly the best sci-fi novel example of an Incident Pit is "The Wreck of the River of Stars" by Michael Flynn. A ship's crew independently make a set of small decisions, any one of which would not result in failure, but in total which result in the loss of the ship and much of its crew. It is much more character-driven than most sci-fi, since the story is basically about a breakdown of teamwork due to the crew's inaccurate perceptions of each other.
Help a Frustrated Developer to get back into developing…
Hello Hacker News. I am a software developer/engineer that has gone through the management path, and didn’t liked it.

I have been out of software development for 8 years, and now I want to start learning new technologies so that in the soonest possible future I would be able to get a job in development.

I know OOP and procedural programming, but I want to either do front-end or back-end development, or maybe both. But the problem is that it is overwhelming the amounts of new technologies and languages to learn.

What would be a good path for back end development? And front end? What about desktop Java development? And for each case, what would be the top 3 or top 5 books to follow/read at each step?

Thank you very much. A frustrated manager.
I don't think tapes replaced LPs so much as supplemented them. With the exception of the car-mounted record player that was an option on some Chryslers[1], the advantages of 8-track and cassette were their ability to take your music with you on the road. I still listen for the "clunk" of the 8-track player changing tracks in the middle of Rush's YYZ..

I think the bandwidth problem of providing high-quality streaming music could be solved by a peer-to-peer system (put your already-downloaded library online for others to listen to). But the record companies would strenuously object -- with good reason, even even if access were controlled via encrypted subscription.

If I were a multibillionaire, I'd do the same thing: build really cool stuff and solve problems I think are important that no one else is really addressing appropriately. I'd be building spaceships and flying cars and things like that, just what Musk is doing (well, not flying cars, but close).
