Group work is awful in regular classrooms.

In a specialized environment where everyone actually cares about the subject, group work can be fantastic. This is why hackathons and similar settings are good things - everyone is there to learn, and you don't have demotivated people who are content to sit there and do diddly-shit.

In contrast, in your standard class, where most people couldn't care less, the result is that the one motivated person in the group does the bulk of the work, everyone else gives a token effort, and then educators pat themselves on the back for "facilitating peer collaboration" or whatever the ed-speak buzzword is.

Edit: The fun part is that teachers know that this is what happens, and the result is that group projects end up being hilariously easy if you get a group of kids who actually care. They're built for one person to do!

> There are plenty of real, non-physical things. Evolution is real, and non-physical, you can describe it using mathematical formulas. Math decides how the real world happens.

Math is an invention of man it doesn't exist in the real world. There is matter and energy and they interact. Quantities of stuff exist but there are no numbers. That is extrapolation and modeling with man-made tools. Math decides nothing as it is not a fundamental aspect of reality.
I know it pretty well. My stuff generally renders right after the 8th or 9th try / refresh!
Kids don't destroy your sleep pattern unless you abuse them by going against millions of years of co-sleeping and throw them in a crib in a different room (doubling their risk of SIDS). In a year and a half we've had exactly one "troubled night" and that's because she had hand foot and mouth disease.
Children cry because something is wrong. Sometimes that may be "I want to pull the cats tail but she's running away" but more often than not it's something that can be addressed by a parent. Love, attention, and affection has solved every bout of crying so far.
For what it's worth, vigorous exercise is barely more than walking:

E.g. if you do an hour on the elliptical machine at 150 bpm then that's already 80% of your exercise RDI for the week.
Huh? IQ is a number representative of not much. Take 3 tests and get three results. Perhaps we mean something more general, like speed at skill learning?
And by innovative we of course mean: intrusive.
In response to his "responsive numeric stepper," he could have substituted over 20 lines of CSS and eliminated the unsavory plethora of element-specific media queries if he'd just used non-breaking spaces (`&nbsp;`) to achieve the desired line breaks.

Better yet, he could have set `white-space: nowrap;` on `.passenger__label` instead and just thrown a `<wbr>` element before the first parenthesis.
Real world financial transfer systems are often used for net settlements. And writing the entire history of the world's transactions on a single append-only ledger that has low throughput and costly storage may not be ideal, while approaches like Lightning might allow instantaneous transactions.

Still many ifs, but if it works, there could be some interesting advantages for speed and scalability.

"Learn cantonese". Let's see how that one goes. Click.

"I would like to welcome you to the Cantonese lessons. I'm here to help you (bold)learn Cantonese(/bold)". Hello there, content-farm-robot-pretending-to-be-a-person.

Lesson 1: "Cantonese Alphabet". There is no alphabet in Cantonese, it's a Chinese language. Click.

"Today I will teach you the (bold)Cantonese alphabet(/bold). If (...more filler...). Cantonese contains more than 9900 letters". Hu, OK, let's stop here for the 'alphabet'. A quick look at the other 'lessons' shows what is obviously missing but would be in any true '101' Cantonese course: it's a tonal language, so you'd have to explain the tones first.

If you skim through multiple languages you will see a 'Translation' service (with a paid option, but it's the same page as the free one) that always point to the same (stock photo) translator. Not sure what that website is for, but it's not for learning any language.

I clicked on Cantonese as well. Their "alphabet" is just a bunch of Hanzi with Mandarin Pronunciations next to them.
It's just a vapid meme, which hopefully will eventually die off. We took it out of the title above.

Summary: reduce alcohol, don't smoke, stay fit.

Yet another super long article that the bottom state the obvious.
Imagine a long hallway segmented with closed doors, where each door represents a decision made during a mission. As you continue walking down the hallway, opening doors, the morality of each decision becomes more difficult to square with your original frame of reference. Finally you encounter a door that you decide to leave shut.

That is roughly how it works, self selection. The SF groups that, to put it charitably, operate under legally ambiguous circumstances are people who know each other really well, and they only invite in those who are a known quantity. There isn't any kind of laboratory-prisoner-execution/choose-the-red-pill sort of test, the evaluation occurs continuously in the daily performance of one's duties.

SEAL teams are, relatively speaking, high profile SF - and therefor much less likely to be tasked with strictly illegal and morally objectionable missions. I have a lot more trust in someone who has SEAL team affiliation towards the end of their military service. They've walked the hall and stopped opening doors pretty early on, so they're a well measured quantity.

Also, it is my experience that veterans with combat action ribbons are far less likely to mindlessly appeal to state authority or be swayed by utilitarian justifications. Of the dozen guys I've kept in touch with, most are libertarians and a few are anarchists. I guess seeing the ugliest side of the state will flip a switch :)

Your last comment on the seemingly circular relationship between Clara and a "turing-test-passing bot" is especially salient. This reference (found in the second footnote in the post) http://www.ijcai.org/Proceedings/95-1/Papers/125.pdf has a lot of interesting perspectives on the role of machine learning vs. human intelligence.
They have an advantage that their own local market is quite large (and growing). It's similar to how a US company can do very well focusing on just us consumers, because the market is so big. Or, same as Japan .

That may purely be a symptom of age though on my behalf.

I still remember the first time I tried visual basic and had a form display. I instantly wanted to display some characters from a game I as playing (ultima online I think), and I need up writing a script creation program for a free server a friend of mine was running.

Raw Alignment
Sure it does: the sub-human conscious experience of a paramecium is what it's like to /be/ the part of the universe comprising the paramecium. Although that part of the universe is as much a paramecium as the part that's human is human, so I don't think what's going on there is 'sub' human. That said, there's less complexity there, so it seems like being that part of the universe would be less 'interesting'--but then again, that's just a human value judgement and probably similarly irrelevant to the universe and paramecia. Neurons aren't central to what I'm talking about; I'm just applying something like a variant of the panpsychic hypothesis to the human situation.
I was intrigued by the "why are traffic lights red, yellow, and green?" question at the start .. and then the article didn't actually give an answer!

Decent overview of the origin here: http://www.todayifoundout.com/index.php/2012/03/the-origin-o... Most interesting, they originally used white for "go", but ran into big problems when the red colored lens fell out by mishap!
I've used maybe 20 different ereaders on various devices. Pretty much all of them have some stupid fatal flaw on them. None of the vendors ever respond to my suggestions.

1. touchscreens and eink do not mix. give me fwd/back buttons

2. the newer kindle can only remember your last read place in one pdf. Open another pdf, bam, you're reset back to the beginning on the other! This makes me furious.

3. Windows' pdf reader ups the ante by remembering the place in the last 4 pdfs you were reading. Open a 5th, and the oldest one gets pushed off the bed. You'd think with a 512G machine there'd be enough memory to remember 5, maybe even 6!

4. no MicroSD slot in most of 'em

5. miserable bookshelf display. Come on, how hard can this be? Just look at a real bookshelf. Do it like that. Click on the 'spine', and you can then see the front and back covers. I'd like to sort the bookshelf by a 'star' rating I assign myself, so I remember which ones I want to read next.

6. some correctly display the first page of the book as the thumbnail. Some display a stupid generic PDF logo. It makes you want to scream.

7. Microsoft does even worse, if you add a folder.jpg of the cover, it warps it into some ridiculous trapezoid, surrounded by so much whitespace you have to do lots of scrolling.

8. The Kindle DX has this stupid toggle button that sticks up so it's easily busted off.

Amazon got it (mostly) right with the ancient Kindle 3 (the keyboard one) and my beloved Kindle DX. I am very careful with the DX so I don't damage that button! I regularly buy their newer Kindles, and they just wind up in a drawer somewhere or given away as I go back to the old ones.

iBooks in the iPhone is pretty good, except for the small screen, which is uncomfortable for dedicated reading. The bookshelf view is barely acceptable, still making poor use of the screen real estate. I suppose getting an iPad would fix that. Battery life is an issue for it.
> why do VCs make founders jump through hoops that don't matter?

Depending on the celebrity of the VC, I can imagine a truly massive deluge of cold emails mostly from supremely unqualified companies.

I can understand their desire to be insulated from that.
I disagree. You've described a very good way of actually conducting science, which would probably be more reliable than the way we've been doing it. You italicised "disprove" in your earlier post because you know that when people do science, they don't try and disprove their own view. At best, they come up with experiments designed to disprove someone else's view. In reality scientists are searching for data that can be comfortably explained in terms of their view but which cannot be so comfortably explained in terms of competing views.

But the thing about science is, that even though people are doing it wrong, it still works. Science is somehow robust even to such fundamental mistakes, that it ceases to be science.

Then again, we might have spent the last century or so building a completely false model of the universe because our technique is wrong, because we haven't actually been conducting science according to the sort of definition you give. It's worth considering, but I doubt it's true.

At some point I really should just sit down, make, and then work through a bunch of box model excercises. After 8 years of trying to treat CSS display as a sensible thing, I've concluded that I really just need to learn it by rote.

> an organization like the EFF could make it a policy to publicly disclose when they've been hired or terminated by a client

I've worked at EFF for a long time and I don't believe EFF could adopt such a policy as a matter of prudence -- or legal ethics. I can tell you that there are many reasons that lawyers will regard the existence of conversations, client intake, consultations, and representation relationships as confidential. In fact, they see that as an important principle of legal ethics.

You can see some discussions of the confidentiality of the fact of legal representation as a matter of legal ethics at

https://www.google.com/#q=legal+ethics+"fact+of+representati...

Many times, EFF has to talk to clients and prospective clients about matters that, for a variety of reasons, it's not EFF's place to make public. Just as a start, it's important that people feel comfortable talking to our lawyers when they have questions about their rights in a particular situation, whether or not we end up going to court for that person, and knowing that the matter won't end up in the press or be revealed to other parties as a result of those conversations. Lawyers can also become subject to protective orders issued by courts specifically instructing them not to reveal information about a case.

Legal matters are sometimes embarrassing. Many people who've been sued, arrested, indicted, investigated, subpoenaed, or who anticipate a possibility that one of those things may happen, aren't necessarily keen to draw any further attention to the situation. Often, people involved in legal issues are quite anxious and distressed about what's happened to them. Sometimes people ask lawyers for help dealing with other people's improper disclosure of personal, private information, and naturally don't want their lawyers to draw more public attention to what's happened.

And people who are considering filing a lawsuit, giving information to a journalist, launching a new product, introducing or changing a corporate policy, or responding in some way to a government request, among other things, may have various acknowledged and alleged duties and responsibilities to other people. Announcing or implying that a particular legal case, issue, or situation exists or that a person is taking legal advice on a certain matter could have significant repercussions. It could lead to claims that someone has breached a duty of confidentiality, or it could damage personal or business relationships.

This isn't an exhaustive list of reasons that lawyers will keep confidential the fact of representation or the fact that a prospective client has sought legal advice (whether or not the lawyer ends up representing that client on an ongoing basis), but hopefully it helps to illustrate that this is something that lawyers take seriously as an ethical matter.
Your definition of physical existence above is not circular in some sense, it is circular in any sense since you define physical existence in terms of interacting with other physical existence. Just to test your definition, are colour or sound physically existent in your definition?
> "Why are traffic lights red, yellow and green?"
> When a child asks you a question like this, you have a few options. You can shut her down with a "Just because." You can explain: "Red is for stop and green is for go." Or, you can turn the question back to her and help her figure out the answer with plenty of encouragement.

My wife and I were just talking about this idea at dinner. There's this really deeply held belief that you have to struggle with something in order to learn it and value it. It shows up everywhere in our society. From the title, I was hoping this article had some data either for or against, because I'm interested. It reminds me of some of the new thinking going on like the basic income project YC is running - maybe struggling is only valuable sometimes, maybe sometimes it's harmful and only slows progress.

One thing we've noticed with our kids is that they learn some things faster if we give them the answer without making them struggle or stop to do "constructive thinking" or whatever. This has made me start thinking about how animals learn things by example. We don't withhold the right way to say things from babies, we just show them and tell them, repeatedly.

We tried to use allowance to get them to value and budget their money and earn their keep with chores. It was a constant battle. We switched to allowance comes with no strings, and they can spend their own money on whatever they want. Chores are simply an unassociated responsibility that can't be questioned, and it's like night and day - they do extra chores to win approval, and they're saving up for months for games and game consoles they want.

This stoplight parable is an unfortunate example of an arbitrary human system, they could have used something from the natural world instead. Making a kid stop to just guess at the answer is, I'm sure, about as fun as when kids ask me "Guess what?". I'm running out of dad-joke responses.
Take a look at Stuart Hameroff's research. He is definitively doing that
>What's wrong with BMI for something like this?

How many runners do you know who would complain about BMI? Or weight lifters? It's the fat people who don't like it.
> How are you even still in business???

People who are in dissonance ask questions that have no answer. I would respectfully ask that you refrain from making blaming statements and asking questions with no answers.

I actually wrote out a whole reply for you which put a double bind on your argument, but then I said "fuck it". I'd rather eat dinner with my wife.

Did you get an email from my friend a while back about the possibility of buying real/high quality soy sauce? I'm not so much curious about the actual exchange, just reminding you that there are other (food) things that are hard to get outside of Japan (partly due to the language barrier, and not all traditional crafts shops being particularly Internet savvy) -- that a lot of people would likely be willing to pay a premium for. It would proabably be a quite different business model - maybe enough of a change for you to keep your interest (and us to get our good stuff). I know he did sign up for the candy either way, and was very happy that I pointed him to your service ;-)

Btw, for others interested in good food, and/or Japanese food, the inspiration for this request came from the excellent documentary:

This cocky attitude fuels racial discrimination and should be strongly condemned.

If you have some basic ideas about human history you should know that the Arab world helped preserve a great deal of classical knowledge from the Greek/Roman Era while the "Western Civilization" f*cked itself so hard in a cultural regressive "Dark Ages".

All human inventions are progressively built on past discoveries and you should be ashamed for only taking things at their face value.

Does anyone have a pointer to a list of these lists? Would be interesting to know what models people use on a day-to-day basis, like usesthis.com for the brain.
Unless you're a hot company, the power imbalance favors the VC.

This means you should be communicating on their schedule, not yours. Email is async and hands down beats phone calls (which are synchronous).

Also, a lot of people really just hate phone calls. I won't even talk to recruiters on the phone—if they try to call me, I tell them to send me an email.
My heart was in my mouth reading this; what a moment to have been alive. I can't begin to fathom the emotions for all involved. It must have been terror mixed with elation, doubt, fear, hope and wonder. Any small mistake from the ground or space crew regarding any number of tiny details could have ended the mission. I'm in absolute awe of the training and skill involved.

Does anyone else know of similar accounts of early spaceflights? I'd love to know if the audio from the radio is available too.
The truth is the opposite, and always has proven to be: the natural sciences are the only way to acquire real understanding, while every form of mysticism by which "nothing is beyond us" ends up being us fooling ourselves again.
The agricultural revolution was about feeding the massive postwar population boom.

I'm talking about the 1890-1940 activity to make food safe. Stuff like mandatory pasteurization of milk, wholesomeness requirements for meats, etc. You had early 20th century Typhoid epidemics in NYC fueled by bad milk.
Using company.com makes for better metadata, in two directions.

It makes it easier for them to immediately look up your company just from scanning their inbox. If they later come across your company separately, it makes it easier to find your message and to follow up on the email thread (they probably don't remember your name).
This is super useful, I have a similar list but it also includes techniques and ideas

* Dimensionality Reducing Transforms
* Hysteresis, Feedback
* Transform, Op, Transform
* Orthogonalization for things that are actually dependent
* Ratios, remove units, make things dimensionless

A big one, that helps me immensely, is that when I need to do a big/risky/complex task, is to imagine myself doing with with sped up time. Instantly creates an outline and list of tools that one will need.
