Those are all good points.

I think my basic objection is it feels like I'm being deceived. It's like going to a concert and finding out they're just playing a recording and pretending to play their instrument live or sing live. Sure there's the crowd, the venue, the stage, the show, but at a basic level I paid for a live performance, not a recording. Similarly I paid for a meal made by the restaurant, not made by someone else and just served at the restaurant.

Just be honest about it.

I don't get upset when the menu says "Donuts from Dynamo Donuts" or "Ice Cream from Humphry Slocombe" so tell me "Chicken Kiev by Sarah Lee" if that's the case.
Remarkable story, thanks for the pointer.

This is so important. It's incredible the difference it makes to the difficulty of the exercise let alone the damage you prevent to your body.

What would be awesome to take this idea a step further and create a Kinect app (or perhaps some other related/similar tech) which could determine if you are executing the correct form and make suggestions about how to correct yourself. This could also be used to monitor your progress in getting more flexible (e.g. in yoga).

EDIT: Obviously, not applicable to this app, but the idea stands nevertheless
That may be true for researchers, but there are a lot of implementors who take original research and try to apply it to problems.

I just wanted to point out, that even though I'm not in the target, the product looks excellent. I can see by the level of presentation and the way labels are created that you've put a lot of time and effort in developing this, there aren't many products these days that show so much accuracy from early stages. Great job!

As a programmer I don't make videos, I write source code. We're not talking about me waltzing off with the git repository, but of me videoing my software as it does what it does. I for one, after 20 years experience mind you, have never signed a contract explicitly forbidding me to make a video of the product that I worked on running. I think that most other programmers are in the same boat. Which means that for most programmers, unless you are aware of a specific legal protection afforded to viewing software in action, your advice is scaremongering, and not helpful.
Cool idea... but doing some back-of-the-envelope calcs on this, I get:

Yield, assuming 3 harvests/year = ~ 24,000 l ethanol per year

Price of ethanol =~ $1/l... if feedstock = 50% of price, then value of beet grown = ~ $12,000/year

Neglecting all running and maintenance costs,to get a 6% return you'd need to cover your hectare with conveyor belt for $200,000... that's $20/m2, inc substructure. Considering carpet costs $40+/m2... I doubt this could be done economically.

Comments?
This is SO well done. So, so impressive.

A side question, for any doctors on HN-- I'm really curious, what do you think about the Blood Tests section? That is, the benefits of monthly blood testing. From talking to one earlier today about related topics (coincidentally!) I could imagine the following response:

1. The ideal ranges for each value on your blood test do not necessarily represent the ideal range for you personally -- and not only do they not necessarily represent the ideal range for you, if your number is outside them and you're otherwise asymptomatic, your number is likely already "healthy" (with very few major exceptions like blood pressure and cholesterol.)

2. So by doing this, you aren't actually tracking things that need to be improved, or rather, you have no way of knowing if you'd be "more healthy" by being within range

3. So, getting monthly blood tests is useless, and any changes detected would also be useless

4. (And as an aside, annual physicals for young healthy people are not beneficial (and can be harmful) to health)

Is this right? Was I just talking to a curmudgeon? Tech-optimistic doctors, what do you think?
Then there's how to read a research paper for hackers.

I see each article as a patch. Our minds are both running operating systems and decentralized repos. Each of us are specialized and running a different custom OS, so may require different sets of patches.

Science is specifically concerned with our mental models of how the world works. Different fields in science are like different levels of abstraction in programming.

My specialty leans more towards higher levels, so subjects like psychology, philosophy, biology, are more relevant to my mental model than lower level mathematics, chemistry, and physics.

When I read research articles, I'm primarily interested in extracting an abstract high-level idea, which I can apply to my repo. I start with the end of the abstract, then discussion, conclusion, results, to find the main point, then only look at details if I can use them.

Once I have a simple idea, I merge it by connecting it to related ideas in a functional way. Each idea then becomes like a code snippet of a function, and my process of learning is like coding, where although you may copy/paste a snippet off the web, you still need to reason with logic to connect it into your code so it actually works.

If I can't make something work right now in my repo, it doesn't commit, so is temporarily stashed, where I may either forget about it, or come back to it if I find the missing pieces to fit it into the working directory.
As someone who's parents are going through this I cannot disagree more. There are circumstances where it does happen.

I don't think this is YC's goal. I recall comments from pg to the effect that if all the companies raised money on demo day, then maybe YC wasn't selecting properly (for the risky, out-there, stuff).

>The average maximum force the bricks can stand is 4,240N. That's equivalent to a mass of 432kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000.

>So, 375,000 bricks towering 3.5km (2.17 miles) high is what it would take to break a Lego brick.

>"That's taller than the highest mountain in Spain. It's significantly higher than Mount Olympus [tallest mountain in Greece], and it's the typical height at which people ski in the Alps," Ian Johnston says (though many skiers also ski at lower altitudes).

>"So if the Greek gods wanted to build a new temple on Mount Olympus, and Mount Olympus wasn't available, they could just - but no more - do it with Lego bricks. As long as they don't jump up and down too much."

Well, in theory you can go as high as you want, by tapering the tower towards the top. The 3.5 km limit is only valid for straight, constant cross-section structures.

Which mountains certainly are not.

Me too. I've had jobs where I had to work in areas with high foot traffic, lots of distractions, I could never get in "the zone" and never got any real work done. Well, looking back, I did get some work done, but I always felt like I was too distracted to focus, and it definitely took me a lot longer than it would have otherwise.

I'm afraid the one-page review assignment part at the end of the article won't give much satisfaction to the instructor who came up with it. A lazy student could simply paraphrase the paper abstract to address the first two bullets (summary, arguments, conclusions).

I think asking for a one-page detailed example and illustration of the paper would force a more careful read, and would be more interesting for sharing with peers.
Sounds interesting. Could you maybe post a couple of resources that you found useful and would recommend going through? Thx!
I'm intrigued that they keep pointing out that it's not using any asm.js optimisations, but still "performs well".

"Performing well" in this case still means significantly slower than Firefox does on the same code:

Which isn't to say that it's not a big improvement over where it was. But there's still a way to go on making it competitive, so far as I can see.

Thats what the AGPS system is, the Almanac and Ephemeris data is provided over a data channel from a server rather than directly from the satellites.
The idea being that receiving the data over a dedicated data channel is much quicker than a low-power broadcast from a sat.

This is often confused for a similar mechanism for triangulation of a position using the relative powers of multiple cell towers. This provides a low-resolution position fix suitable for use as the initial seed of the kalman filter (which narrows down the position iteratively).

Why Data Visualizations Provides You a Competitive Edge
Unfortunately I think the increased complexity in javascript engines is also a security risk.

Fuzzing and other techniques may be able to cause all sorts of crashes and memory corruptions in the jit compilers code or in the generated code. This issue may have just been amplified by the extra complexity in the massive amount of LLVM C++ code added.

This is less of an issue for llvm when used as a static compiler, but as a jit on untrusted code, I don't know.

Time will tell, but I wonder if Rusts memory safety will make it a better candidate for implementing advanced JIT engines that process untrusted code than C++ like in LLVM.
Hi, I have several good ideas, some of which I've already implemented on my own property, and thousands of (possibly) less viable ideas in my wastebasket. I'm an automation programmer/sysadmin and so everything I do has to be automatable. I've found thought that often things can be automated naturally, without arduino or anything. Here are things I would look at doing:
1. Grassland management. See Alan Savoury http://vimeo.com/80518559
Note: I would do this with a honeycomb structure of hedges with automatic gates.
2. Aquaponics. I have just finished/am finishing a ~60,000L aquaponics system at my house. Naturally automated (other than planting and harvesting, which can be automated/made efficient. See my blog (posted below)

Also read up on Ben Falk's research. If you're honestly wanting me to put something in place, we'd have to discuss the details and we'd have to fly out and put things in place. I lived in Wisconsin for years but I'm working in London now and honestly I'd be VERY interested in trying some things specific to the mid-west. Good luck! Oh, to contact me, jump on #opensourceecology on freenode and shout for me I'm always on.
True but people forget (or don't know) that calories from fat, protein and carbohydrate are not the same! The metabolic fate of these components explains why this is a fact and not, as stated on many links, a 'suggestion'.
Here a small Hack. You can scrape a local list of new incorporations, and set up a system to check for them on google. If one don't get results, could be interested in your services, so contact them. I think it's feasible, to scrape an official list and a small script that searches google from that list, as the names of the companies normally appear in the legal sections of web pages. Regards.
(oh, and, the pet theory also includes occult Illuminati-ish inauguration rituals for C-level executives. "swear to $DEITY that you will spend lots of dough on fun fundamental research or forever stay the meager mid-level manager you are". Candles, catacombs, robes, distant humming male background choir, that sort of stuff)

(they'll keep the shareholders in check by a mixture of nonsense and honesty about why IBM really needs to do so much fun fundamental research. if all C-level people talk the talk the same, and otherwise don't suck at what they do, then i bet they can keep the shareholders from getting all too grumpy about spending $3B on something that might pay off in 20 years, maybe)
Yeah, seems to me like this article is just advertising for YC. The only real content is the suggestion that biotech is now viable for accelerators/VCs but with no citations that point is weak. Not that I mind reading about YC's investments, it's just that Hacker News articles generally contain at least SOME useful/interesting content.

Last time I looked, the canonical manuals for the ARM architecture were quite expensive. If anyone has advice on piecing the basics together please let me know. I don't know much assembly, am currently playing with 6502 assembly, and have been writing a 32-bit VM just by working it out as I go.

I do have a set of reference manuals, opportunity purchase, for acorn-era ARM systems. What sort of consistency would I find between historic ARM instruction set and the latest 32 and 64 bit versions?
Identifying different behavior in genders doesn't exactly make him sexist. Not in the bad sense anyway. Personally i think the notion that both genders behave identically (on average) is flawed.

But isn't a tower characterised by its straight construct as compared to a mountain (or say, castle)? Although, I guess you could describe a mountain as 'towering'.

Of course, you are right, if they built a LEGO mountain, they might pull it off; but that wasn't what they was asking for.
Introduction to APIs
It's funny; As I get better at any given language or system, I inevitably move away from frameworks into individual libraries more and more. I don't think it's to be effective as much as because it's fun to force yourself to learn the things you just don't when someone else has handled it for you; then again, I still use Rails in my day job and Ember for my side projects.

At the same time though, I love having a good list like this. If I could have this for Golang, it'd be a godsend. Having an upkept list of relevant libraries to put things together makes so much possible- if not for certain libraries existing, I don't know that I'd ever have embarked on many of the projects I do. They make me realize how much more is possible.
Actually, punching a kid in the face in the middle of class was a viable strategy for getting adults to deal with bullying when I was in school. They could ignore the bullying up until then, but once there was a physical altercation in front of them, they had to admit there was a problem.

I got suspended (1 day out of school, 2 days in-school) but the bullying got dealt with. YMMV

I don't really care about the new logo. But I do wish that the "new airbnb" allowed me to sort the listings by price. This is standard practice on any other site I can think of. Sure I can set a price range but this still forces me to have to think. I like the fact that when I sort results I know that as I continue scrolling the price is going to increase. That way when I find a place I am happy with I know that there is not going to be a place further on which is better value. Please let me know if I am just being stupid and have not figured out how to sort the results.
A good joke for the morning, thanks :).
Well, you are flying a semi-toy without proper safety near people, buildings, above roads, cars, etc on a tourist site. An arrest might be slightly over the top, but this should not be allowed.

I'm a model RC pilot for 20 years and these kind of "stunts" are hurting the hobby. At least ask for permission next time.

A phantom only has 4 motors, and the quality is "meh" - there is hardly any 2nd control (fa I have tripple recievers in my jets, if one RC system fails I still regain control over another radio).

It has a "failsafe" - i=even if it works it's still not really good in an urban area. GPS signals might be weak (flyaway danger) and it's only flies to 25 meters when returning to home. It could fly into a tower or even not reach proper 25 meter when the 3D GPS lock is weak or disengaged.

My 2 cents. Sorry. Please people, don't fly above crowded areas. I've seen a Phantom hit a car it's almost 1KG of deadweight when it comes down. It's only a matter of time until someone gets hurt.
PDFs don't necessarily support that. Some PDFs draw a lowercase i by drawing two filled shapes, more draw it by calling a function that draws two filled shapes. And, yes, some draw it by invoking 'i' in a font.

I think the main draw is that the wallet is being built with first-class citizenship for many of the features that provide maximum anonymity. Most other wallets seem to be implementing those things slowly, without a real roadmap. Also, those building darkwallet are some of the folks who spec'd out the BIPs for those features (if i understand correctly).

"Features" being these: [1]

- built-in implementation of COINJOIN protocol for mixing

- STEALTH ADDRESSES for address re-use. As i understand it for darkwallet, the sender can take one recipient address (like a public donation address), and create a dummy transaction with data that only the receiver can decode, containing a private key with the funds. So the receiver scans the blockchain looking for the dummy data, and can claim it, but it looks like two separate transactions. Kinda like a drop-box with cryptic public note telling that the recipient will recognize as a clue to where the money is :) [2]

- MULTISIG - being done elsewhere, but prioritized highly here.

- various UX stuff like pockets and identities to help ensure that separate histories never mistakenly mix

Still investigating it all, so likely got some stuff a little mixed up

Most of these "libraries" are way less than 1 Kb in size, so why is it a factor so important it must be emphasized this much?

Also the colors make my eyes bleed, so I had to close after a few seconds. Nice dataset, bad presentation.

Also, can JavaScript developers finally learn how to program instead of looking up 0.03 Kb sized "libraries" for every tiny thing. I'm all for code reusability and 3rd party software, but you need to consider the cost of each dependency in your chain. Small utility one-liners rarely worth a full-blown package.
