I define my mind as everything there is out there, so, obviously, everything is in my mind. But we have science, precisely, to try to understand what it is out there, and "out there" means outside of our minds.

But that is the very point of solipsism - because you are experiencing the outside world only through your senses in your mind, you are unable to decide whether the outside world even exists. The two options are 1) your body with your brain and your mind exists in the usual universe and you can learn about the universe through your senses and 2) the usual universe does not exist, only your brain or your body or something along that line actually exists and the entire universe you think exists outside of your body is just something your mind made up, your mind is simulating the universe for you.

So this is not about redefining mind to mean all the universe, it is about emptying the universe until only your body or your brain or whatever remains, dreaming or hallucinating or simulating the thing we just got rid of all day long so that you can not tell the difference.
Yes, the syntax is LaTeX (thanks to MathJax). See Chapter 2 of the bookdown book: https://bookdown.org/yihui/bookdown/
Yes, habit is about cues. Time is one cue, but it can be a weak one if your ordinary routine varies. If you set your exercise time as 6pm, but your activity at 5:30 is not routine, then the time cue may not be enough to trigger the habit. You'll lose track of time and suddenly realize it's 6:15, at which point (like this comments says), you'll feel like you failed and you'll rationalize not doing it at all.

The key is to entrain a new habit with an old one---exercise when you get up, or on your way home from work, or at some other point in the day where you're reliably doing the same thing every day.

I'm vegan but I'd never make stuff up. Notion of food being unhealthy or healthy is borderline orthorexic. Saying that red meat is unhealthy is vague. There's no concept in science that categorizes food as either healthy or unhealthy. There has been no strong evidence that diets containing meat are unhealthy.

As much as I'd like everyone to severely decrease their meat consumption and eventually stop using all animal products I won't scare them with shaky facts.

Would USA population benefit from eating less food, definitely. Are epidemiological studies strong enough evidence for diet related health benefits? No.

HN is full of orthorexic hivemind demonizing ingredients like sugar, cholesterol, fat, meat or whatever.

There are plenty of valid, rational reasons to stop eating meat. If one is in good health then health is not a valid reason.
Hell yeah I have been. And then realized it was stupid later.
No, the speed of light is the same in ALL inertial frames of reference. This is the crucial postulate from which all special relativity comes as a consequence.
Very good, thanks for sharing. In fact, last week I had the idea that there was room in the world for a tool like this.

Why so many people here attack so aggressively anyone who even suggests that Europe should not let everyone in?

There are many countries which limit immigration (USA, Australia), or even make it practically impossible (rich Gulf states, Israel, Japan). But you don't compare them to 1930s Germany, do you?

Why do you think that Europe ought to accept everyone who wants to live in there?

I checked some profiles and it seems most of you live in the US. Why do you fell entitled to teach other people who they must let in into their houses? And compare them to Nazis if they don't want to?

Not to mention that it is US who created this whole mess in the Middle East...
Sorry but I don't think "AI winter" as a term
is appropriate here.

The "AI winter" as I know it was around 1988.
I've still vintage issues of "AI Expert" and other publications of the time (which I kept for their great linocut-style artwork, and because they were expensive items here around).

Back then it wasn't so much about ML (aka "Deep Learning") but anything Prolog, expert systems, artificial neural nets and their generalizations, and Lisp.
Neat! Extension methods and getting rid of "var that = this;" in one!

It seems that it also extends to full expressions on the right-hand side of ::, so you can even do, for using Array operations over things that look like arrays but not quite:

document.querySelectorAll('p')::([].map)(f)

instead of:

[].map.call(document.querySelectorAll('p'), f)

(replace [].map with Array.prototype.map if it feels less gross)
Is more from old habits than a badge of honor. Fewer new developers use emacs or vi for coding. But I think "single digits" is too low too. I've been to talks by Microsoft engineers where they code using vi or emacs. One of the reasons is that the IDEs are always a step behind the languages.
Note that the business itself is on sale and will hopefully carry on, albeit in a different place. The saccharine post seems to tiptoe around the real issue: Alan Hughes is retiring and is cashing out by selling the building separately from the business. Because of the London property market being what it is, that building is likely the largest asset the business ever had. It would be trivial for Hughes to sell the building, relocate and carry on; but he's only doing half of that, and if a buyer for the business can't be found, "well that's too bad".

Alan Hughes might be a man who "embraced the patterns that prescribe his existence", but he's clearly decided to cash in, tradition be damned. In that, he's more consistent with his generation than the umpteen that came before him.
Actually for a photon time is so dilated, it does not exists anymore. From its perspective everything "happens" at the same "time". There are quite a few answers for this :

.. and more to the point perhaps there is something to the statement that "those who insist on using purely pharmaceutical means to treat diseases are holding back research into the power of the mind to heal itself, i.e. the theory that a majority of ills (particularly mental-health) are psychosomatic is being under-explored because there is too much money to be made in selling drugs".

I mean, its not a popular opinion, but once the door is opened to start questioning either side of this argument, the sky is the limit.
Developers who've significant experience with functional programming understand that it would be easier and more reliable to solve many (or most) problems using a functional language over an imperative one. But the majority of developers have little to no experience with functional programming. In almost every conceivable way widespread adoption of functional programming would make everyones jobs significantly better. And these days we are beginning to see mainstream imperative languages starting to incorporate functional concepts slowly because people are starting to realize the value of it.

Right now we have far superior tools available to us than the ones used by the average programmer, but due to a combination of historical reasons, poor education, and sheer inertia of past commitment to inferior tools, we don't yet see widespread adoption of the superior tools that are already available.

The visual languages that I've seen so far are a kind of adaptation of existing languages to make them simpler and more accessible to beginners. What I'm talking about is not merely simplification of existing languages, but more a shift to an entirely different kind of paradigm. A shift that would require the development of new abstractions that are uniquely suited for visual programming that are not just adaptations of existing abstractions.

But as with all tools there are limitations. Certainly visual languages will not be best tool for all jobs, but there are certain classes of problems that are going to be easier to tackle with a visual language. There is also the possibility of solving a particular problem (or different parts of the problem) with both visual and text-based programming concurrently. First class support for data structures like graphs are easier to do with a visual language. I use Neo4j for graphs and the cypher query language is quite good, but it's effectiveness comes from the fact that it incorporates visual elements within the text. Something like MATCH (n)-[:REL]->(y) is a query for matching a part of the graph but you're still limited by the one dimensional structure of the language. You could imagine a visual query language for graphs being vastly more powerful in ways that a text based language couldn't possibly be.

Very good question. Speaking honestly, I had no awareness of that at the time I started. I was super young and very naive about the idea of equity -- I accepted what they offered me without reading the fine print or exploring the implications at all. I am fortunate that the founders of Kickstarter are incredible upstanding men and really looked out for me, but (for the record) I do not recommend this tactic for any other first hires. :) It is incredibly important to do your research, dot your i's, cross your t's, etc.

People have good reason to doubt food science "experts", the current obesity epidemic is thought to be from bad recommendations of the food pyramid.

Jotvid - Easy video notes
Last resort testing
Hey, 3D vision system amateur here, but very interested to learn more!

Can anybody point me to some literature or reference materials about attempts to combine the inputs from multiple techniques simultaneously?

E.g. a device with stereo conventional cameras and infrared cameras & emitters which compares the resulting model from each input source/technique and actively re-adjusts final depth estimate?

Is "sensor fusion" the right jargon to use in this context?

Or, even crazier, a control system which actively jitters the camera's pose to gain more information for points in the depth map with lower confidence scores / conflicting estimates?

But maybe such a setup is overly complex and yields minimal gains in mixed indoor & outdoor scenarios?

There's John earnest's oK on github (am on phone right now or I would link). It's a JavaScript implementation that runs everywhere.

K is not more polished, it is differently polished. It is much more minimal than J, which makes the syntax simpler and thus the shortest program is often longer and slower in K; however, in my experience typically the length and performance are on par.
Totally depends on what type of person you are. Are you incredibly self-motivated and comfortable setting/pursuing your own goals? Do you have a wide skillset and/or if you don't know how to do something, are you willing and eager to figure it out? Then get in at the beginning, because that temperament will take you far. If you are more comfortable with structure, experienced management, and a clearly defined role -- enter at a later stage, when more administrative structure is likely to be in place. Just my two cents!
Hi Cassie. How do you believe a Kickstarter campaign can be a precursor to an Equity Crowdfunding campaign on platforms like VENTURE.co?

It is a universal constant. See above.

The photon travels at the speed of light c. If you look at the expression for the time dilation, you will see that it tends to infinity as v approaches c. Remember that this relates the time experienced between two frames moving relative to each other at a constant velocity v. However the fact is that the expression fails when v=c, since you have a division by zero. This reflects the fact that it is impossible to do a Lorentz boost that relates two frames moving relative to each other at c. This in turn means concept of time dilation in an object moving at the speed of light, such as a photon, is meaningless. There is no such thing as the time experienced from the point of view of the photon.

I realise I probably wasn't very clear, but it's difficult to lay it all out in a small paragraph.

It only makes a difference when you finally face real adversity. I'm a serial entrepreneur. I've had 8 companies, 6 of which have failed. Twice I've been literally reduced to the clothes on my back (actually the second time was even worse: 30 grand in debt, to the government).

When shit goes REALLY bad, your ability to deal with the nastiness of reality is put to the test. I fought for a month and a half with a broken rib, because I refused to give in. I've climbed out of some very nasty holes and endured the most humiliating circumstances holding my head high, because I will not concede defeat. If I have to die, I'll kill my enemies first. If I fail, that's MY fault, not other people, not circumstance. I have sole responsibility over myself, EVEN if I'm not the one who got me into the mess originally. It's MY responsibility to get out, and no one else's, because let's face it: no one else gives anywhere near as much of a shit about you as you do.

The speed of light does not change for each given reference frame, i.e. it is constant. However, space and time are observed differently depending on a given reference frame.

With regards to your second question, photons experience no time whatsoever. From the photon's perspective, they travel the universe from the point of emission to the point of absorption instantly.

If you want to understand this, I highly suggest watching this video explaining reference frames: https://www.youtube.com/watch?v=aRDOqiqBUQY

Of course! Many things were much easier to manage in the early days, when there were just a few of us, and we functioned like a family: there was lots of time for conversations, Feelings, and talking things through. That naturally ebbs once a company begins to pick up steam. I will say, though, Kickstarter's core spirit was (and has been) remarkably consistent, and I think that's because of the consistency of vision from the top.

Can I write Clojure that gets compiled to JavaScript with ClojureScript and run that on JVM's JavaScript engine Nashorn?

Obviously turning code into JavaScript at least once is a mandatory requirement for fulfilling the "web" part of "web scale" and running the JavaScript on JVM gives me the "scale" part.

I think if you read the essay you might get the idea that he wasn't being entirely serious and re-read it again in that light.
Like GP, I thought I had cleverly thought of this idea up myself. So glad that smarter people than I have did this up right!
I think the point of the essay was that the affect that some modern readers interpret as arrogance or even phoniness was actually a sly humor. If you see his work as a prescriptive how-to, you'll see his writing one way, but if you see it as winking, wry social commentary you'll read it another.

That's not to say that this essayist's point of view is "correct," but I found it to be an enlightening point of view.
Why wouldn't they already be maximizing their own profit today?

The moment I didn't have to explain what we did anymore -- to anybody. Which happened remarkably fast. People would say "What do you do?" and I would say "Kickstarter!" and I would see their eyes just light up. It was very cool and exciting.
That's an older form of ranging. It's easier to do than pulse ranging, but you have to outshine ambient light at the color being used full time. The Swiss Ranger [1] is a good example of such a system. It's indoor only and short range. With a pulse system, you only have to outshine ambient light for a nanosecond, which is quite possible in sunlight.

I've been expecting good, cheap non-scanning laser distance imagers for a decade. In 2003, I went down to Advanced Scientific Concepts in Santa Barbara and saw the first prototype, as a collection of parts on an optical bench. Today ASC makes good units [2], but they cost about $100K. DoD and Space-X buy them. There's one on the Dragon spacecraft, for docking. That technology isn't inherently expensive, but requires custom semiconductors produced with non-standard processes such as InGaAs. Those cost too much in small volumes. There's been progress in coming up with designs that can be made in standard CMOS fabs.[3] When that hits production, laser rangefinders will cost like CMOS cameras.

Recommended homeschooling bloggers?
Hello,

This is the first time that I'm posting here and I hope that I'll be getting some replies. I've been following the boards for a long time but didn't have the guts to post until now.

So here it goes... Who do you think are the top homeschooling mom bloggers out there? I am working on doing an interview with them and I need all the help I can get with building the initial list.

Thank you!
It's just the process of organizing your ideas in a logical order. At the start, I have a bunch of ideas and I do my best to organize them into an outline. But as I begin writing and continue my research, I realize that some of my ideas suck, or I have new, better ideas, or I see a better way to share my ideas with the reader, so I need to constantly reorganize my document.

I don't know if this process is a sign that I'm an amateur writer or not, but Scrivener makes document organization incredibly simple compared to writing in a normal text editor. It also enables me to keep my notes sorted without interfering with the prose.

By the way, updating all the references is very easy using Bookdown and a bibtex bibliography.
"Does anyone here use any lisp for Web Development?"

The code behind the site https://news.ycombinator.com is written in a Lisp: http://arclanguage.org
Clojure is pretty drastically different from Lisp in most ways. If you wrap your head around macros in Clojure that will mostly carry over to CL, but just about everything else will be a learning experience. They're both very cool languages, but much more different from each other than for example Python and Ruby are. If you're interested in Lisp, learning Clojure first is sort of like learning Spanish because you're interested in French.
But it's much more difficult to steal my Bitcoin because I don't go around typing the private keys in plaintext nor are they printed on a plastic card I carry around in my wallet.

Credit cards need velocity limits and insurance and fraud checks and all that stuff mostly because their actual security is godawful.

Anyways all I'm saying is that for certain people and certain transactions, Bitcoin is superior to credit cards. For everything else there's Mastercard.

> I doubt you'll get that, because nobody thinks that progress in machine learning will stop.

Robin Hansen is notoriously skeptical about the possibility that Deep Learning can make real gains. He for some reason thinks brain emulation is more likely to make large progress in AI.

>An AI winter doesn't mean that progress stops.

It doesn't completely stop, but progress would be at a snails pace.

> The hype then dies down. Research continues, though, until enough progress is made that machine learning starts to produce results that excite the public again, and the cycle goes into another hype phase.

I think we as a community may need to take a good long look at the hype cycle theory and be skeptical it has any merit.
It's a tradeoff. Maybe most people just don't think slowing climate change is worth reducing meat consumption.
