This was surprisingly beautiful. As a geek in programming/computers/information/mathematics, but only a physics admirer from afar, it is very suggestive, even natural, to explain the deepest physical reality in terms of information:

"It was as though particles gradually lost their individual autonomy and became pawns of the collective state. Eventually, the correlations contained all the information, and the individual particles contained none. At that point, Lloyd discovered, particles arrived at a state of equilibrium, and their states stopped changing, like coffee that has cooled to room temperature."

“What’s really going on is things are becoming more correlated with each other,” Lloyd recalls realizing. “The arrow of time is an arrow of increasing correlations.”

“The present can be defined by the process of becoming correlated with our surroundings.”
I had problems getting an upstart script to recognise 'source' - it had to be . ./foo. From memory, 'source' is a bashism.

It's an inapt comparison and the comparison should not be made naively.

If I spent the next 6-12 months writing libraries in Rust targeted towards Python-level code, we could spend time comparing Rust + those libraries vs. Go and have a productive discussion.

Personally, I think that Go is a clumsy language, a chimera of C plus Python, having neither type safety nor significant abstraction nuance. More sophisticated minds than I have flamed Go in depth, I won't bother parroting them. :-)

Go's primary advantages are:

1. Google.
2. Targeting the Python/Ruby developers & needs.
3. Compiled & statically linked
4. Relatively stable.

Rust's chief disadvantages are:

1. Still < 1.0.
2. Semi-manual memory management. Gc'd pointers are kind of a pain.
3. How many pointer types again? >.<
4. Strongly typed. [1]

If I was given a mandating hand to develop a reliable and efficient system for most applications to maintain (with funding) over the 5-10 year term, I would be OK with choosing Rust today, with the expectation that we'd have some porting and heavy lifting as things change, possibly even contributing development time to the Rust project.

[1] Probably should expand this. You have to spend serious time understanding how the type system works after you get into the more advanced type systems. Haskell, ML. It's a disadvantage for quick learning and the quick hack to get the system working. Changes simple in a less typed language (e.g., Perl) can have non-local type ramifications in a project. /me handwaves. It's double-edged.
Batteries are really hard.

The combination of electrochemical systems, with mechanical requirements make the tradeoffs subtle and the gains sometimes elusive.

Ex: We tested some new SLA(Sealed Lead Acid) batteries that claimed 20% improvement. They provided very close to that number. But they were totally unacceptable for us - the plates were too fragile and were breaking/shorting in transit.
This is okay, but what about showing the actual queries? What about showing how long each query took? I wrote some code that actually logs all this information directly to Chromes Console log. Pretty awesome: http://bakery.cakephp.org/articles/systematical/2013/05/08/h...

Wow.. this is missing the entire point on why lens blur occurs. Lens blur in normal photographs is the price you pay because you want to focus sharply on a subject. The reason photos with blur looks "cool" is not because the blur itself but its because the subject is so sharply focused that its details are order of magnitude better. If you take a random photo, calculate depth map somehow, blur our everything but the subject then you are taking away information from the photo without adding information to the subject. The photos would look "odd" to the trained eyes at best. For casual photograph, it may look slightly cool on small screens like phone because of relatively increased perceived focus on subject but it's fooling eyes of casual person. If they want to really do it (i.e. add more details to subject) then they should use multiple frames to increase resolution of the photograph. There is a lot of research being done on that. Subtracting details from background without adding details to subject is like doing an Instagram. It may be cool to teens but professional photographers know it's a bad taste.
The framework battle is really between Backbone, Angular, and Ember. No one else I can think of off hand has the marketshare that those 3 do..

And each has their own strengths and unique opinions. My preference is Ember, but it's just that, a preference.
I mostly agree with everything you say. I think it's sad that so many in our industry use such poor tools. Racket, for example, is an excellent tool for beginners. The PLT group that produces it has long had a focus on introductory programming and has produced resources such as HtDP (http://htdp.org/) and Bootstrap (http://www.bootstrapworld.org/) yet Racket is far more capable than Node, Ruby, and the like.

As someone who has tangentially interacted with YC, I seriously doubt that is the reason. YC cares about the team above all, then followed by customers/users/traction (but really, it's the team). The addressable market is not very high on their list of concerns. Though it certainly is a factor, I don't think it is the reason for rejection.

One question I have is how well does the team know each other? What are some of your team members' accomplishments? Honestly YC doesn't care very much about all the degrees you have (I would even argue that the fact that there are 5 degrees among the 3 of you is a negative signal for YC because it indicates credentialism, but that's just my opinion).
Quantum mechanics is where physics became more like mathematics: common sense no longer provides much guidance. It is really cool that it provides the missing explanation for one of the most common sense ideas in classical physics: the arrow of time.
Point Grey Research makes stereo and 360 cameras. They aren't really designed for consumer use though. The Nintendo 3DS also comes with a 3D camera.

I can think of a few reasons why you don't typically see this in consumer products. First is cost. You need two lenses and sensors. Second is workflow. There isn't a lot of consumer level software available for processing image pairs to get and use depth data. Third is display. Most people don't have 3D displays for looking at the final result. What else is a consumer going to do with this data? Points two and three combined lead to low demand for a product that does this.
Why do they use `::before` instead of `:before`? Is that a typo?

If his goal is to make meal replacements, optimized for health, why are the meals lacking on this point?

I'm dying to give this a try.. but i also don't want to hurt my body. To be frank, i've got no clue what the health risks are, i just hate eating 90% of the time, and as a result i eat very poorly. I don't go fast food or anything, but i often skip meals or substitute some random protein (cheeses/etc) just to make the hunger go away.

I'm ready to order 2 weeks of this stuff tomorrow, would better minds than mine care to elaborate more on the health risks/points that coolsunglasses brought up?

Thanks

Animal protein isn't a human requirement there are plenty of other amino acid balanced sources.

As far as I understand it this has very little impact on the security of OpenSSL and can only be abused by someone with access to a signing system (and then you have more problems anyway).

What happens is that during the signing phase the certificate up the chain is read and checked, then during the generation this root certificate can be swapped out form underneath the process, and the generation proceeds as if nothing happened.

This means that the newly inserted root certificate is inserted into the chain of trust, while it was not explicitly added.

Magnetically Actuated Micro-Robots for Advanced Manipulation
core.async [1] is basically the canonical example of a Clojure library that relies on macros to do its job, although surprisingly few macros actually need to be exposed in the public API. Most notable is the go macro, which performs deep-walking code transformation on its body, permitting clients to write async code in a straightforward, boilerplate-free way.

There's usually a heavy emphasis in the Clojure community on keeping macros as small as possible – the thinking is that any behavior that can be implemented with ordinary functions should be, and most macros should be lightweight wrappers over these functions. This seems to fit together well with what I've observed: functional programming idioms often circumvent some of the more common legacy uses of macros in practice, relegating macros to a still-essential but less prevalent role.

The reasoning sounds a bit iffy as in:

“Finally, we can understand why a cup of coffee equilibrates in a room,” said Tony Short, a quantum physicist at Bristol. “Entanglement builds up between the state of the coffee cup and the state of the room.”

I think you can understand coffee cooling quite well without any quantum stuff - the atoms in the coffee are moving faster than those in the room. There will be a tendency when one impacts with an atom of the air in the room for that to speed up and the coffee atom to be slowed.

Actual quantum entanglement is a strange and interesting thing. It's a shame people tag the term on things it is not really relevant to try to sound impressive for the most part.
I've always wanted to study quantum mechanics because of this very "entanglement". Can people please post recommendations on good resources/books on the topic for a person like me having no solid experience with physics(except college level courses)?
That is not true. Stopping down the lens aperture increases the depth of field without reducing detail in the focal plane, until the diffraction limit (around f/16 for a 50mm lens on a full frame DSLR).
Nice! Since they got a depth map, 3D-scanning can be a next step.
Hate to be a naysayer, but I think you are reaching too high with this. Knowing how to cut videos in a meaningful way is not something that can be accomplished with current state of the art A.I as it requires a higher level of cognition. You need a human to tell what content is interesting.

You can't predict which situation will teach them more. You can safely say that they'll learn different things in each situation. Starting and running a company can teach a lot of things like budgeting, hiring, firing and interacting with employees, project planning, fundraising, bargaining, conflict resolution, sales, working with whatever tech the company uses. An internship will have less variety and more focus. If you're there to write code you'll learn more about writing code and the planning and processes that go with coding in a professional setting. You'll also be exposed to experienced developers who can show you tips and tricks they've accumulated over years. What ends up being better depends on what your long term goals are.
I'd love to read more about Future[T] and how that type works. Got any more reading on it?
The physical implications of entanglement might be strange but on a mathematical level it's all just vector addition so it's not really that strange.
NICE. This shit is dope.
Wow, just today I read this:

and I thought it was all explained quite simply
and now this?
You've come to the crux of the matter - but I think this is a battle we can win.

I was recently in BC, Canada, and I was purchasing a SIM for data use, and was told that it was, "Unlimited for 3 days". When I asked them "How much is unlimited" - I expected to have to dance back and forth a bit before getting an answer, but the sales rep instantly said, "4 gigabytes."

I then noticed on the brochure that I got from them, that the plan clearly was listed as, "Unlimited data over three days up to 4 gigabytes"

I guess that could be considered winning half the battle.

Even better, though, is Singapore - where there is no concept of "Unlimited" with Singtel - word never appears anywhere. You purchase data packages with very clearly listed time and data amounts. And, if say, you want to use 100 GB - then you go purchase 14 GB for S$25, 4 times. Couldn't be more straightforward.
I do not understand what you mean by "Shallow depth of field is artificial in all cases. Your vision doesn't really work that way." If I hold my hand very close and focus on it, the background obviously becomes blurred.
This is a good driver for tech. It makes sense for everyone to have their own battery at home to be like a google server ups... Distributed is far more reliable than centralized. Heck the power grid wouldn't even have to be 24/7 anymore if it could handle both the peak current and deliver enough average power.
I lived in London for 5 years and used grocery delivery services a lot. Now I live in Seattle, and don't use them anywhere near as frequently.

There are many difference between grocery shopping in the US and UK cities, but by far the biggest is that in London, a lot of people live without a car. This means walking or taking the bus to the supermarket. (Eg: in San Francisco, 28% of households have no car [1]; in London that number is 60%. [2])

Home delivery allows Londoners to buy the type of and volume of products you want. (I'd rarely buy a 6-pack of 2-liter orange juice cartons alongside the rest of the groceries when I had to walk 30 minutes back from the store.)

Without a car, you also have to make more frequent trips to the store, increasing the overhead of shopping. Being able to drive to the store for a 'big shop' every week or so is much more efficient.

...but to be honest, in everyday work Javascript feels a lot like a bondage and discipline language, because it lacks so many features and in practice you always use a restrictive "coding guideline" and a linter configured for the maximum strictness you can have, so you end up with a pretty verbose, retarded and restricted dynamic language. In order to keep your sanity and be able to work in a team in Javascript you basically have to throw away the baby and keep the bathwater to work with :)
The rate of information increases.

Hence why

Information wants to be free.

Parasitic on

Only information explains its own existence.

Which all, I think, intuitively follows from Spinozist/Cartesian "Conatus" principle. That is to say:

The order and connection of ideas is the same as the order and connection of things.

Some of us rave about this or that: "well, how many folk use X today" or "qualify as X" or "subscribe to X". But these expressions are all within the scope of multiply converging nexuses of increasing correlative potentia. The coffee cup is a simple example — so like Wittgenstein's point: "if a lion could speak, we could not understand him". The lion, like the cup, has restricted correlative powers: these laws apply, these others do not.

The laws of information are laws about the dimensions of proportionality, which give the arrow of time an aspect of curvature (needing to exhaust a universe for exponentially narrowing arrows, so the onion-skinning of properties of a thing "come way may" at "frozen" temporal localities — what happens when we "bend" time at certain family resemblance (physical) properties?).
> OpenVPN is hard to setup and maintain.

That's not true. OpenVPN is the easier, most straight-forward solution when it comes to set-up[1] and configuration (routing, firewalling, client auth, etc.). Try to setup OpenSWAN and you'll see what hard to setup really means. I don't know about new software like SigmaVPN.

[1] Or maybe I am too used to it.
I thought it was the second law of thermodynamics that already explained the arrow of time? Well, that and friction?
One of the most amazing quarks of the American legal system is how you can rescind, revoke, and give away your rights which are protected by that very same legal system, and it's all perfectly legal to do so.
oh, yes, indeed, the ->> macro is slick. reminds me of the bind operator in haskell. i don't know why i haven't seen something like it in other lisps. but as you said, that's part of the language.

anyway, should clarify: i'm interested in libraries that define and then use lots of macros in order to solve a specific problem. i'd like to know what problem domains are particularly well suited to the sort of language extension that macros provide.

Ask HN: What source code is worth studying?  
This is one my favourite questions, asked by idlewords: https://news.ycombinator.com/item?id=879101
But its been a long time since then, and with a new set of programming languages, I believe there are new code bases that's worth studying about and learning from.
So, which code-base should I be reading about to improve myself?

Yes its interesting; you can easily imagine that the following trends are detected:

* "home and safe" "safe as houses" etc

* "safe in bed" "safely tucked up in bed" etc

* "volcano" ... no clear data. Certainly dangerous being a volcanologist, but that'd be great AI googlefu

* "pensioner attacked in park" .. "our parks are not safe" etc... Hmm, Parks are the most dangerous.

Because frequency of local newspaper reports is a bad measure for volcanos I guess.
What would you say is the biggest benefit compared to Photoshop?

Do we need entanglement to explain the Arrow of Time? Even though in classical mechanics, the past and the future are both equally observable, we remember the past and not the future because the future does not contain certain information yet -- the information to be introduced into the universe in the form of quantum fluctuations. One could even argue that all information in the universe was created at some point in time due to one quantum event or other.

I may have misunderstood though (I'm not a physicist). Entanglement does however, explain why systems tend to equilibrium rather than any other type of state as it evolves forward in time.

On a related note, I found this quote interesting. It reminds me of how HN comments about quantum information theory has a tendency to get downvoted:

> The idea, presented in his 1988 doctoral thesis, fell on deaf ears. When he submitted it to a journal, he was told that there was “no physics in this paper.” Quantum information theory “was profoundly unpopular” at the time, Lloyd said, and questions about time’s arrow “were for crackpots and Nobel laureates who have gone soft in the head.” he remembers one physicist telling him.
Photoshop has been too hard to use for anyone outside the design community to want to learn. It's the new MS word. The export for 1x, 1.5x, 2x, etc. could be useful for making assets for Android.
Reminds me of a hack day at Yahoo where one team made a captcha where you had to match a photo with its tags and another team made an algorithm that would assign tags to a photo. Both based on Flickr humans meant that the captcha was easily solvable by the algorithm.
