Those are good videos, and I also endorse them. However, you will not truly know what is going on until you solve some real problems with them.

One interesting option that computer programmers have to understand linear algebra that most people do not is that you could go do some stuff with computer graphics. Grab three.js, and then once you've followed some tutorial somewhere to get a triangle on the screen, start doing things, but do them manually, including implementing matrix multiplication yourself. Modern graphics has moved so far up the stack nowadays that you probably shouldn't say that you "know 3D graphics" after that exercise, because you'll know 3D graphics circa 1995. But you will have a much better intuition for linear algebra, and those videos will either make sense, or be trivially obvious to you.

(One of the reasons why the linear algebra videos can be so helpful is that it has historically been very easy to take an entire class on the topic and just grind numbers, without ever getting to that level of intuition. Differential equations, if you took physics that did not use them, can have a very similar problem, where you just grind through problems for a semester with no motivation.)
And how do you feel about it?
Why assuming Jus ad bellum or the right to defend your self is valid - there are some forms of killing that are not "evil"

Distrust of the NSA has cost it the deference it was given by academic cryptographers to basically ignore the process norms of public crypto standards. That's not the same as saying the academic cryptography community distrusts a simple ARX design.

It was the huffington post which first pointed out the timing of Trump's ZTE concessions relative to a Trump Organization-affiliated project the Chinese government agreed to finance.

This is the first WikiTribune story I've personally noticed on HN. The story is not as juicy as the headline makes it out to be, but it's good to see WikiTribune as a source of news nonetheless. I'm excited to see more from this site in the future.
People say you have to "do" math to learn it. Usually they make it sound like you need to do the exercises in the books. I think that doing just that can be boring and demotivating.

I would suggest finding projects that can motivate you and help you exercise your math. Some suggestions of mathy things I regularly work on for fun:

1. Make a video game. If it's a 3d game, you'll have to do your matrices, dot products, trigonometry, etc.

2. shadertoy.com - This is a community site where people just program cool looking graphics for fun. All the code is open, so you can learn from it. Similar to game programming but without the mathless overhead. :)

3. Machine learning projects - I love writing various machine learning things, but the project that has been a great ML playground has been my self driving toy car. It gives me plenty of opportunities to explore many aspects of machine learning and that helps drive my math knowledge. My car repo is here: https://github.com/otaviogood/carputer but a much easier project is donkeycar.com. ML will touch on linear algebra, calculus, probabilities/statistics, etc.

The most important thing for learning is to be inspired and have fun with what you're learning. :)

>I am not sure why some people instantly assumes that the whole purpose of making drones more autonomous is to make them more precise: historically, the DoD/US military have made virtually zero efforts to even try to reduce civilian "casualties".

????

That's not even close to true. On any level. You are confusing the inevitable willingness to tolerate civilian casualties with an outright disregard. Civilian casualties have consequences, and they are avoided. Not strictly, but it is a cynical fantasy to imagine that there is a complete disregard for civilians.
Aside from making it easier to get clicks, I think that's just the enthusiasm and the fact that Tesla is the only game in town right now. From what I've seen, when Electrek criticizes other automakers it's because they're not doing enough for electrification. There are many different reasons why automakers themselves are not eager for EVs, but that's what Electrek is judging them on. It's no surprise that Tesla is the standout.
Anything 3D over 720p. 2-year old games are barely playable at 720p low settings. Even faster memory doesn't help much. But for photo/video editing it should be totally fine ;-) For HTPC in 1080p even the BayTrail-based NUC 2820 is totally sufficient (e.g. Kodi).
Ocam's razor, so yes.

I learned very young there are differences, like I literally (NOT figurative at all) couldn't see the motivation behind destroying school equipment, drawing on walls, etc. While for some, it's fun.

But even after all those years, it's just so hard to wrap my head around that.
I think the thinking (I'm not defending it) in some circles is that the courts are slow and expensive. Anything that keeps disagreements out of the courts is a win for society. If accidentally run into your mailbox, rather than requiring you to sue me, we can come to an agreement outside the courts. This is much more efficient.
> "So the “moral” engineers have an incentive to stay and act as a front line against “immoral” actions, or at least have an insider’s position for whistleblowing."

This is true if the engineer is in such a position of power within the company that he can effectively influence things towards the ethical goal. Most of typical for-profit corporation engineers who care about that ethical goal have no such position. If they strongly disagree with what they contribute to, the best decision for them and the ethical goal is to quit.

It seems bad that huge centralized social networks like Twitter have such societal influence and can unilaterally decide to do stuff like this, and all users can do is trust them not to fuck it up.

There's an obvious way around this: use a decentralized, open source social network like Mastodon or Pleroma instead. You don't have to trust any one group not to screw things up, because you can just switch instances or forks if they do. But unfortunately, because of network effects, alternative social networks are not very good for people who care about reaching a very wide audience.
I'll second this idea having survived a Physics BS doing just this. I'd also strongly recommend a series of books called Schaum's Outlines, they vary in quality but cover many advanced topics and have hundreds of solved problems in them.

Without knowing any more about what you are trying to do, I would just recommend a framework we learned at business school that I keep coming back to. It's for when you're looking at developing or altering a product. It's really just a checklist, and it's super simple, but it's effective. Can be tweaked to understand how different brands are attacking a market.

5Cs, STP, 4Ps

5Cs: Just list out a bunch of facts to get acquainted
- Context: what are the wider trends (e.g. millennial habits, etc.). This is where you start wide

- Customer: what 'job' is your customer trying to do? Who could that be? What is your unit of analysis: a person, an occasion, a ___ ??

- Company: what are you good at?

- Competitors: Who else is trying to serve that job?

- Collaborators: Who could be a partner? (Vendor, complementary service, channel partner, etc.)

STP:

- Segmentation: What are the different customer segments? What are the dimensions that make two {people, occasions, etc.} different in a meaningful way

- Targeting: Which are the viable and nonviable segments? Who's your target?

- Positioning: What is your:

-- POP/POD: point of parity/point of difference

-- Frame of reference: who are you stealing share from?

-- Reasons to believe: why would someone believe that you can deliver?

4Ps/marketing mix:

- Product/brand: what is your product? what's it's functionality? what's your brand?

- Price: level and structure.

- Place: distribution channels. Pull vs. push.

- Promotion: where will you advertise? What's your message?

> The schools won't allow my kids to use Wikipedia as a source

Would they allow your kids to use Wikipedia's own sources — as long as they're legitimate — as their sources?

I do not trust traditional journalism as a source either (unlike Wikipedia and most schools). I try to find their sources; and when I can't, I regard it with suspicion.

This is either incredibly childish or too subtly tongue-in-cheek for me. Neither is the article "mine" in any way, nor was I "mad". I was genuinely curious.

The problem that they are carrying concealed weapons is minor compared to the problem of giving out cop badges for money. Just when I thought I couldn't respect cops less, they do this. It's not a few bad apples, it's a barrel full of only rotten apples.
The Constitution mandates that people have the right to bear arms; it doesn't specify about concealed carry or open carry. Yet I, as a Californian, can do neither. Open carry is illegal in California, and only a small few can get a concealed carry permit (varies by county). It is very clear that Californians' constitutional rights are being "infringed".
Hi HN, I'm excited to share the public release of Bowlcut with you. At Pollinate we've been developing and using an internal version of this library in production-facing product customizers since late 2013. Bowlcut was originally developed to create vector logos for sports teams, but it could easily be used for more complex graphic design purposes.

There's not a lot out there in terms of frontend SVG text layout and distortion libraries, so I'm eager to see how the greater web uses Bowlcut. Since this is one of our first projects to open source, I would appreciate any feedback you have on the structure and documentation of the library.
Second "The Devil's Candy," even if you're not interested in Bonfire of the Vanities at all.

I haven't read the book or seen the movie (yet) but The Devil's Candy was an incredible look into how badly things can go in Hollywood. You can probably generalize it to any large project where multiple competing interests all have a stake.

I second this but starting to watch actual undergrad lecture series is beneficial because sometimes the book your working through May just be missing that one piece of the puzzle you need to start getting enough of a grip to solve a problem.

Also with physics, you need some tricks that are usually done in derivations or calculations (cause not everything can just be solved) and those do not necessarily appear in a book - but they do in lectures.

Edit: the book gives you the fundamentals though on which you work. also, they will teach you the necessary abstraction - the first thing standing in my way of a degree in physics was my intuition and need to picture stuff. working a lot with differential geometry now, I've got some of that visualization back but with linear algebra even and quantum mechanics it can stand in your way.
https://books.google.com/books/about/Physics.html?id=8MvvAAA...

Is it that the text you’re referring to? We used the 5th edition in my physics course this year. It was a tough textbook to learn from but I feel like I learned a ton.
I understand the desire for uncensorable communities like that, but how do you suggest decentralized systems combat the "un-moderated communities tend towards hate filled dumpster fires" problem? Even light touch moderated communities tend to be more cesspool than not.
Also, I should mention, one big lesson learned... Maths build on each other. Don't be embarrassed to start with a pre-calculus text/course.

You probably don't remember much from high school, and most low-div calculus problems are some simple calculus rules combined with a bunch of high school algebra/arithmetic manipulation that if you don't have it all ready at your fingertips, you _will_struggle. (this means memorizing all those trig identities again) The hardest part of low-div calculus is this stuff... The actual rules of calculus are simple, easy to grasp and dare I say it, intuitive.... if you can do the pre-calc.

You seem to be suggesting that the fact of one's residency in a country should influence one's moral evaluation of that country, that there should be a different set of standards applied to one's own country than a foreign country. I believe that standards of good and evil should be applied uniformly to all nation states. If anything, one should hold one's own country to a higher standard since you have the most hope of influencing your own nation's behavior.

Arguably, it is precisely the inability to consider international conflict from a vantage point outside a nationalist worldview that is the root cause of all external wars.
Exactly. Every time I tutor someone in math, I tell them to use up at least a sheet of paper for every interesting question. When they do, their skills improve quickly. Saving paper is a false economy when it comes to math.
Satellite data suggests that China, Russia are fudging their GDP reports
I'm referring less to the rounding and more to the way it's representing scanlines/interleaving of output, which while "signal accurate" isn't really "experience accurate", and if you're going as far as to emulate the rounding of the monitor, you really don't care what the signal was, you care what the person saw, and because of CRT bleed, that's far worse than some other display options (even repeating lines looks more accurate in some circumstances, I think).
If you're going to say that the US has brought hell to Pakistan, you should at least back it up with some reasoning. What would Pakistan look like right now without the US killing those 4000 people? What would surrounding countries look like? Why did the US kill those people? Would any other country in the US's position have reasonably killed them?

It's a complex issue that can't be summed up by saying "fuck that".

domain registration data is in a weird place for the modern internet. I can see the value of having a real registry when it was first developed, but now it seems like a pretty easy way for people to shoot themselves in the foot with regards to privacy. Also, some registrars charge a premium for WHOIS privacy. It should not cost extra to have your legal name and address to be hidden from the entirety of the internet.

The standard library is not going to have more advanced features than what the community can do, if only because of the release cycle.

Meanwhile, I was not a user of attrs before, rather I used collections.namedtuple and then typing.NamedTuple. So, data classes is a win for me and other people like me who weren't using attrs. And you can continue to use attrs without being bothered at all.

In Raymond Hettinger's talk [0] at PyCon 2018, he even says that more features from attrs will likely get added, such as data validation [1]. And that his talk was the one chance for the developer (Eric Smith) to get praise, because everyone is going to instantly second guess every decision he made.

Interesting. I have absolutely zero ethical concerns with Google building a drone which can more accurately target someone. I'm also perfectly fine with US government using those drones to kill bad guys.

Now if they use it to kill good guys, then it's a problem that needs to be solved.
It's really challenging to unpack this kind of dogmatic argument. Are you a pacifist in general? Are you against violence and military intervention in every conceivable case, up to and including Rwanda or WWII? Do you think it's good for relatively liberal and democratic countries to have less military capability than relatively authoritarian countries?

The cause of human rights, freedom, dignity, and survival would have been actively harmed if British and American scientists and engineers took the same moral stance that you're taking and refused to participate in the war effort. Do you think it was wrong of Turing to help break German encryption?
I believe that's the point of the comment you are replying to. You may develop weapons believing in the goodness of your country's military, but those weapons may come into the hands of people with more dubious moral positions.

We could have gotten nuclear tech without the will to kill people. There are smart scientists outside of the military, and a need for power plants. Which everybody agree would have been built with safer tech without the need for the bomb.

Now the problem is never the tech, as usual. It's that the society we are living is not constructed in a way that can prevent the tech from being abused.

We are talking about a country that attacked Irak while lying out the WMD and against the vote of the majority of the world, killing countless people for no proven result and living a country still in ruin decades after that.

Ask HN: Samples of Employment Inventions&Assignment Contract Benefiting Employee
I am a software engineer who is about to sign an agreement titled "Inventions and Assignment Agreement". There are certain parts in the agreement such as "the Company owns all, ideas, work, inventions, ..., etc during work hours and after work hours, weekends and nights" which is throwing me off and this is just one of them.

I like experiencing with new technologies and like building new things on the side which i like to keep as my own.

I would like to come up with a different or my own version that does not claim my soul os their property.

Is there any sample agreement i you can point me to or advice you can give me that i should put under protection somehow?
You need to cross reference things like Hollywood accounting[1]. Profit can be manipulated. The original Star Wars movies have never made a profit. Let that sink in. Corporations and the rich are quite good at cooking the books for a variety of purpose in order to subvert the will of the people. So "profit" is not a good measure. They're too good at lying about it in the right way.

The difference is the cost to yourself, or people you care about, when you want someone dead. Popular sentiment turned against the Vietnam war in the US because Americans were coming home dead, not because of the Vietnamese that we were killing. When we eliminate the cost of war, we make it more likely to enter one, and stay in one.
I take issue with this is a rather rigid classification of things, that isn't useful, and I hear a lot out of various modern scientist/philosophers.

> There is nothing supernatural; there is nothing outside of or distinct from Nature and independent of its laws and operations.

It's pretty common to associate supernatural with magical because super-natural sounds like beyond the rules of nature, when it can just as easily mean beyond the known rules of nature. If you can't explain events under natural law (rules, whatever), it's practically and effectively supernatural. That doesn't necessarily exclude a future explanation, just because people have been averse or ignorant, to investigate in the past. Straight from history, countless supernatural events have been brought in to the fold.

Otherwise, this guy sounds like he had some contemporary beliefs shared by rationalists.

Which is a very plausible assumption, considering dropping traditional bombs is much more inconvenient for the killers. With drone attacks, the cost and political fallout is minimal. And with more meal available, the appetite grows - the killers will use the new capabilities to do more killing.

This has changed somewhat with the decline of Moore's Law. Companies are keeping equipment longer, past the point that OEMs typically provide warranties or even parts.

When you know that's going to happen you want to start with something that uses standard parts rather than vendor-specific ones.
