I don't know much about core math, but what are is the "context" the parents are missing? It seems to me that the homework is going to pretty hard to solve if it doesn't contain the complete "context." Or is he referring to some terminology that the parents probably don't know? Why is this context missing, or not available to the parents, if nothing else via the text book or handouts?

And how many different ways is there to add two numbers?
> How would content producers possibly deter copying without exerting control on the consumption hardware and software? The only answer there is standardized DRM.

They could use the legal mechanisms that have existed in copyright law for a long time: they could find, and sue, infringers.

Part of the problem with DRM is precisely that it shifts the power to decide what infringement vs. fair use is away from the legal system, which has checks and balances and has to keep the interests of the public in mind, and toward those who control the technology. That is not an appropriate shift: copyright is a legal right to certain forms of control over work, given to creators as a compromise. It provides an incentive for them to produce that work, which is in the public interest. But how far that control extends should be a matter for the law, not media companies, to decide.
Awesome. :) Please note that that date is an 'expected launch.' Things are progressing nicely, but that's not a hard date. But soon!
Interesting thought. In the history of man, I wonder how many people have ran or came close to running an impromptu 4 minute mile due to being chased by an animal or other human beings and having their life on the line? Perhaps zero. Even if a human had the genetics I doubt anyone would have anywhere close to the world class training it takes. Still, something to think about.
If it's a fresh hard drive, why not partition it?

Unless you are looking to use it on both Windows and Ubuntu, and in that case Ubuntu should have no problem reading and writing to it if you set it up in Windows.
There is (immutable) data and there are modules. Encapsulation / Demeter make it hard to work with data. OTOH, Encapsulation / Demeter are good for modules.
In this case, probably because when you're being tortured, it's small comfort to know how the synapses of your tormentors' brains are firing. Things like defiance in the face of adversity or finding meaning in life seem to be universal across cultures, and a lot more fundamental to the way our brains work than something like scientific understanding.
I went to a state school and Caltech, which is not an Ivy League school but it is well regarded. The math courses were definitely much more difficult at Caltech. The incoming student caliber is much higher than at the state school, so even the introductory courses are very challenging in comparison. This sets a high bar immediately, which allows every succeeding course to maintain that high bar.

College-aged students are highly motivated, but they are often highly motivated simply to do well at school. Only a minority know what they are passionate about otherwise, which is evidenced by students switching their majors all the time.

I strongly believe that who you surround yourself with determines what you strive to become. Ivy League schools constantly tell you that you can become a superstar, so students believe it and your friends all strive to become superstars.

If your friends are all starting tech startups and you know people who have sold companies, suddenly it becomes something you strive to do. If you hang out with drug dealers then you will strive to get respect in a different way. This social factor transforms people just as much as the classes.
Exactly how would you put your paw up to a mirror without "high fiving" yourself?

Hmm, I find it surprising, hasn't been my experience at all.
Can someone please explain what is the purpose of this. Why dockerize a python app vs. just running on a Linux instance. Also, do you get forever hooked on Amazon services in the process?
Thanks for posting the correction.

FWIW, I think it would be better to leave the original comment, and edit it to say "I was wrong - read below". This way you preserve the context, and also other people who make the same mistake as you (like me!) realize what you think and why it's not true.

Here is a bit from Robert Antelme's "L'Espèce humaine", badly translated by me from the German version ("Das Menschengeschlecht") into English:

"On Sunday we have to do something, it cannot go on like this. We have to get out of the hunger. We have to talk to the people. There are some among them who are rapidly deteriorating, they are letting themselves go, they let themselves get destroyed. There are even some among them who forgot why they are here. We have to talk with each other."

This happened in the tunnel, and was carried on from mule to mule. In this way a language started to exist, which was no longer the language of cursing or something thrown up from the stomach, and also not the barking for a cup of food. This language here created a distance between the human and the muddy, yellow earth, so that he was no longer dug into it, but its master, master even over the empty pocket of his stomach. In the pit, in the bent body, in the deformed head, the world opened."

My guess is that it's only in the 20th and 21st centuries that the "developed" world is bringing back latent talents and skills in the population that were left to rot for a few centuries. The Tarahumara run an easy long distance (100 miles!) pace at around 7:30. Again, my guess is that the lack of a 4 minute mile before Bannister is more likely due to lack of observation than lack of ability.

Let's take a framework I know pretty well: Django.

It's not uncommon to switch from one database to another (say, MySQL to Postgres). Django's DB abstractions keep you from having to really worry about what actual database you're running on; unless you had hard-coded dialect-specific SQL somewhere, you just flip a couple settings and now you're talking to the other database.

Same for changing replication setups, for changing authentication mechanisms, for changing logging setup, for changing how you do caching... all of these are things that can and in the real world do change, either from testing to production environments or over the life of a production application.

So it makes sense to abstract those, and the abstraction is backed by "these are things people have really needed to do frequently".

What I have a problem with, and what I criticize as overabstraction, is when someone then comes along and says "well, what if you replace the persistence layer with something that's not even persistent, like volatile memory or stdout (which is actually logging, not persistence, at that point -- a confusion of concerns!)" And then they write a blog post explaining how really you should keep abstracting to the point that the code can "persist" data to those things.

And that's why I say that the examples almost always feel incredibly contrived; it's like somebody didn't know when to stop, and just kept abstracting everything they could find until they ended up with an overengineered mess. Static/dynamic actually has very little to do with this, since even languages that do static typing in overly-verbose and un-useful ways can handle the kinds of abstractions people actually use.

So I don't see a point in re-architecting for these weird contrived hypotheticals, which always seem to be the focus of whatever we're calling the indirect-abstraction-for-everything pattern nowadays; it produces code that's more complex than necessary, has more layers of indirection (and hence bugs) than necessary, and doesn't actually gain any utility in the process.
The other side of the argument that accessing IP is not a human right is that forcing DRM into every channel is not the industry's right. They're going to corrupt the web with DRM because that's where the users are. Just like they corrupted every other open medium. We were hoping the web could be different and stay open, guess not.
I agree with you that the post is a great explanation of why Demeter is good. All I mean to say is "this is just Demeter" is not a refutation of "I think the Law of Demeter is shit and never follow it." (See my links in your sibling, that's a quote.)
Because such slippery concepts make it more possible to survive adversity. It's almost as if it was a trait selected by evolutionary pressure because those were the mental models that helped their users survive.

Not only that, but apparently mouse movements contribute more toward RSI and carpal tunnel than using a keyboard so it has health benefits too (according to an ergonomics coach I spoke to years ago, this may be disputed by research, for all I know, but it seems reasonable to me)
It seems like the author's confusing two concepts here. He postulates about isolation from human contact, but all his examples are for isolation from sunlight or sensory deprivation. I don't disagree that there are connections between the two, but it doesn't feel like he jumped that gap.

Edit: Seems like the whole article is based on the author's book. So maybe it was taken a little out of context?
I'd agree with it being an "advanced technique" in the sense there's a skill to getting the figure right, but I'd actually argue that when it's optimal, it's because it doesn't require much actual negotiation skill to pull off e.g. in the common situation of knowing they won't pay much of a premium over a well-established market price, you may as well start off with a bigger premium

More negotiation skill is required to credibly threaten to walk away or justify your worth after they've opened by lowballing you.

If you do have reasonable negotiation skills and enough insight into the other party's assessment of your value to avoid underestimating how much they think you're worth, you can probably hint you know the size of that value and anchor their offer to it without making the commitment of an actual offer anyway.

At least we can agree on that. Thanks for the chat.
A newly discovered ancient skeleton answers an anthropological mystery.
Hypothetical test:

With human subjects, we have other ways to gauge theory of mind.

Take the statement, "For example, compared to controls, schizophrenic individuals were less likely to understand a request hidden in a husband’s statement to his wife, 'I want to wear that blue shirt, but it’s very creased.'

Perform these alternate types of tests on subjects in a FMRI machine. Conceivably with enough subjects, it may be possible to discern distinct sections of the brain responding to these questions.

Then test the subjects with the mirror test. Place a spot on the nose, or eyebrow, etc.

The first thing to check is if, indeed, the same areas of the brain respond in the mirror test as in the other non-visual tests. If so, this is an excellent indicator that the mirror test is actually showing what researchers have believed it to show.

The next step would be that if the mirror test proves to be accurate, hook up chimpanzee subjects in a FMRI and perform the mirror tests. See if associated sections of their brains respond as ours do. Further, test this against various great apes. If all of us have passed the standard mirror test, I would hypothesize all great apes will have similar responses.

Things to check for in subjects (human and ape): Mental disease. As is mentioned in the article, patients with schizophrenia would not be good test subjects. Try to make sure the apes aren't diseased in a similar way.
And that's why we have other companies around the world have software for that; that's why we have other types of legislations too: to circunvent DRM schemes.
People are ok to pay. Netflix is a proof.

However, IMO it's still not good enough: Netflix is simple and very accessible, but not enough (recent) content. Because content providers are abusing DRM and it's purpose.
Well, that's the trouble with the all or nothing part of Kickstarter. Each poster he printed was profitable, so he was much better off setting a small goal and making some money, than setting a large goal that he missed and making no money.
I think you should write "rights holders" instead of "content holders". They're two different things.
Unfortunately ^F2 doesn't seem to consistently work in my experience, so I have unmapped it and use a Keyboard Maestro macro triggered by same keystroke globally...

1. Save mouse position
2. Mouse mouse to 0,0
3. Click left button.
4. Restore mouse position.

It's a hack but it works.

I also wish there was a consistent keystroke for focusing to the top-level element of a page in Safari: when browsing using Chrome I frequently use the excellent Vimium extension (Vim shortcuts in Chrome; plus great highlighting of links to pretty much navigate quickly with keyboard only). In Safari I use the similar, but not quite as good Vimari. However I find that after navigating to a page from the URL bar, the shortcut to trigger Vimari doesn't ALWAYS work until I click on the document somewhere...
I think this is a great lesson for any budding entrepreneur. Business Plans get a bad rap around most startup communities, but it's undeserved.

Sure, writing a formal business plan to conform to some standard in an MBA class is ridiculous. And it's true, most numbers in a business plan are made up.

BUT, most entrepreneurs these days never even bother to put pen to paper and think of the basic costs of their business. Sure, some of this post is about mistakes, but a lot of it is things that anyone with a shred of business experience could've foreseen. All it took is sitting down and doing the damn math.

Kickstarter projects aren't exempt from having to make the math work on a business. Neither are startups, incidentally.

The Affero GPL is a modificated version of the common GPL that explicitly handles the case of software used as a service through internet.

It's fairly uncommon, but those projects licensed with this version have specific function built in that allows any user to get a copy of the source code (and you couldn't remove it without breaching the license); and some known names use it (MediaGoblin, MongoDB, Diaspora, Ghostscript, Launchpad, POV-Ray are some examples).

Yeah, the ideal way to do this kind of project would be to do the Kickstarter to raise the funds to create the print (the $15k in sunk costs). It's hard with art though because people are reluctant to buy something they can't see.

Uber $10 Billion Valuation
My cat ignores mirrors. He also ignores screens and isn't bothered by audio of dogs or cats. At the same time, he's very alert and will generally spring to attention if he hears a dog or cat outside. A few years ago he was introduced to another cat, separated by glass, and his reaction was completely different compared to looking at a mirror. I don't remember the first time he saw a mirror.

I think that cats have a pretty decent idea of what is and isn't real. While a reflection may be interesting in that it looks like another cat, it lacks the accompanying sound and smell of an intruder and is therefore safe to ignore.

On a related note, many years ago my family lived in a house with a lot of bird life in the back yard. There was a family of magpies, a number of chickens and a solitary male guineafowl. While moving in we leaned an old mirror against a fence in the yard and it ended up staying there for years.

Initially, the magpies attempted to fight their reflections but they quickly learned that there was no point. After that they ignored the mirror. The chickens never seemed to notice it in the first place. The guineafowl, though, was most interesting. This is a species that forms flocks in the wild. This particular guineafowl, though, had been separated from its flock for years and was completely alone. To begin with it had the same reaction as the magpies and attempted to fight itself in the mirror. Over time, however, this behavior stopped. Instead of fighting, it would simply stand in front of the mirror for hours on end.
By placing what they want to do so far out of the realm of legality that the court battle never happens.

This entire scenario simply couldn't happen if internet were a Title 2 service.
> tldr: At the end of the day, if you want to consume mainstream media, you've got to put up with the mainstream consumption hardware/software.

I don't put up with it, and hence have chosen to avoid devices which would impose DRM on me.

I'm a voracious reader. Several of my friends have asked why I don't have a kindle, and the answer is simple. Kindle may be the best reader right now, but unless I can freely move any books bought for it to another device down the road, I will REFUSE to pay the prices of e-books.

If I can not move it the same way I can move a physical book, I haven't bought it. Therefore, I will not pay even close to the amount of a paperback copy. Something like 30-40% of the physical copy price, at most, would be the correct range. And since I don't own it, I should expect to pay for it about the same amount I would get for it when taking it to a used book shop.

So, in reality the correct DRM'd e-book price for me would be something like 10-15% of the physical book's price. Anything more and I simply won't bother unless the book is supposedly really good. All in all, I'll rather leave the book unread for now and eventually get it for ~25% of the price second-hand.

That's a market the publishers don't make a penny on. Their loss.

Except none of the provisions for paid-prioritization mentions, let alone mandates, new roads. If this were about new toll roads, these already exist and are paid-peering arrangements, CDNs, etc. [1]

These new rules are explicitly about 'traffic shaping', by price, by destination, existing traffic along existing routes.

So this is less like using toll roads to cross New York State and more like selectively saying "everyone in New York State that's driving to a Starbucks needs to travel 10/mph slower -- however they're getting there -- or kick in $2/mo to drive the old speed limit."

[1] Microsoft pays Comcast gobs of money to ensure a performant network connection for XBox Live. This is quite different from Comcast being able to say "Sony isn't also paying us money for better service. Let's slow them down -- to protect the network -- until they pay up."
