Personally, I mostly use favouriting tweets for my own personal needs only - to bookmark some things. My behaviour would be unchanged if favouriting became private and no one was notified that I favourited their tweet.

Sometimes, if I really like a tweet, I'll favourite it because I have no other way to say +1 (other than replying to it). But I must like it enough to want to sacrifice the integrity of my bookmarks.

Based on what I'm reading here, it seems that people have wildly varying ways in which they use favouriting.
> if he's created something that is truly capable of sustaining health for the lifetime of a person he should be rewarded

Why? The world isn't short of food. Food is just poorly distributed, or contaminated, or with insufficient micronutrients. None of those problems are solved by this type of feed.

Sometimes there's a need for crisis feeding of a population - during a famine or feeding lots of people in a evacuee camp or somesuch. Again, this feed is of minor use there.

I guess he's having fun doing this stuff, but it's of no use to wider society. Especially because complete liquid feed of high quality already exists, made by different companies and subject to very high levels of quality assurance.

Thanks for the link. I for one will be implementing this then! Probably start testing tonight actually (I'm excited).
A good version exists here: http://www.planetmule.com/
I happen to think that maven is a good idea in principle, but poorly designed. One fundamental issue is that it does not distinguish between what I call 'products' and 'modules'. Modules have transitive dependencies and tend to have a common structure, and products do not.

When you are building a product (e.g. an installer, some documentation, a website ... etc.) with the build tool, what you create is an artifact, that once built you can treat independently of its dependencies. A module is library code, and when you depend on it you implicitly depend on its dependencies as well.

Build languages/dsls are a complete intellectual cul-de-sac. Java is a perfectly acceptable (in fact quite decent) language for doing build tasks. There is nothing in ant that cannot be equally concisely written in java, given the right library support.

I have written more this subject in the articles on the website.

http://www.ebuild-project.org/

The website is not completely upto date, the latest version is 0.8.4.
>Their conclusion is that a “magnetic hose” consisting of concentric tubes of superconducting and ferromagnetic materials ought to do the trick. They say that a tube consisting of 20 concentric rings that is about ten times longer than it is wide, should transmit about 90 per cent of a magnetic field at one end to the other. Indeed, a tube of just 2 concentric rings should transmit about 75 per cent.

"About 75 percent" is a stretch, at least if the article author and I are looking at the same paper. According to the actual paper, in figure 2e, it looks closer to 68 or 69 percent. Not a huge nit pick though.

>These guys have tested this idea with a single superconducting tube 7 cm long (made of BiPbSrCaCuO) and filled with a ferromagnetic alloy (of cobalt and iron).

How much does a superconducting tube of BiPbSrCaCuO that is 10 times as long as it is wide cost to manufacture? How much does it cost to keep it cool enough to superconduct? It's billed as a high Tc (108 K) superconductor from the manufacturer (Can), but there is no price list to be found. Figure 4a in the paper seems to indicate that this effect is indeed only observed with a superconducting tube with a ferromagnet core.

Regardless, it's still a cool effect to see in action! If there's an actual physicist in the room, I'd love to hear more about Chapter four in the paper. It seems that the discretization to more than just a single Superconductor-Feromagnet pair --figure 2e in the paper is the main graph showing the efficiency gains as the number of pairs goes up-- was done using FET, after a brief justification argument that goes over my head, and was not actually produced and measured in lab. I think it'd be a logical extension (if not an expensive one) to produce some of these higher-paired tubes and take more measurements for another paper.
Thanks, your "x" function looks useful. May I ask about the organization? Why the NN- prefix for filenames? Some type of standard I'm not aware of?
Indeed. To sum up some of the basic issues with his research so far:

Sample size is 1.

He's still eating, just much less often. Some nutrients are only required in very small amounts, which he may still be getting from his occasional meal.

Three months is a very short time frame on which to evaluate a diet. Even something as simple and well-understood as scurvy can take three months to develop. In other words, he could have forgotten something as basic as Vitamin C and still lived this long.

He has something to gain (even if just recognition) from this diet working. He also wants it to work. The effects he reports could be psychosomatic.
I have to say I am immensely disappointed. I pre-ordered/signed up for a devkit over a year ago now. The disappointment level for me is high because I got an email a week or two ago saying it would be shipping to me in May.

I was already disappointed as I felt having backed them (to an extent) for so long, I would at least be getting the hardware before it was commercially available in stores like BestBuy.
Game publishers stab in the dark as to what people want from a game.

That's why it's a blockbuster mentality (not an artform mentality).
I agree wholeheartedly. Unfortunately we're in a country (assuming US) where everyone wants handouts and an even playing field, regardless of their lifestyle choices. People demand their offices install ramps for mobility scooters when they're morbidly obese and it's discriminatory not to oblige, but try arguing your work should open later because you drink too much every night. Overeating and copious alcohol consumption are one and the same, IMO.

It's also easy for others to assume everything they don't have was given to others or comes naturally. Out of shape people give me hell all the time for being in excellent physical condition, but they don't know about the 10 miles of running every day and 6 hours of training I put into wrestling for most of my life, or that I run and lift weights daily and watch what I eat. To them, they're not willing to work on their body to have what others have, but are willing to bitch about it. Granted some people are just born unattractive, but it's amazing what a little focus on your appearance can do to change how you look and are perceived. We can extrapolate unattractiveness out a little bit and look at appearance as well. Would you be fired from an office job for dressing like a bum, smelling like body odor, and looking disheveled all the time? Most likely. Is that discrimination? I would argue it's not.
You are very forward thinking. Soylent is in the aisle one.

Comfort and pleasure are subjective irrational metrics that have a lot of inertia, but that change with time. I'm sure it's plausible that people would love soylent just as much as a freshly baked croissant, but it takes time. The way things stand right now, soylent solves a problem that few people have and it comes at a price that is awful. So, yeah, it's unorthodox.

It's nice to see Facebook is aware of the areas which it lacks in. Just recently (in the last couple of days), there was an article clearly saying how mobile developers are in fact turning away from Facebook, for a variety of reasons. Acquiring Parse is not only demonstrating acknowledgment of this problem, but also providing a potential solution and way to tackle the problem.

Congratulations to the Parse team and good luck in helping to bring more developers to Facebook's platform! Given Parse's success so far, I don't see how or why Facebook shouldn't benefit from this acquisition.

You're right, I could have chosen a better title. This article may have been looking at correlations after the fact, but the conclusion is that present changes in search volume can provide insight into future market movements.

Of course, any real opportunity for a profitable trading strategy using this information would be quantified and reflected in prices, so I don't expect the results to persist over time, but I found the findings interesting nevertheless.

Congrats to the Parse team!!

As a customer, not necessarily happy about this. I don't like Doug Purdy's quote, "We don’t intend to change this." We use Parse and love it. I really hope they maintain some autonomy as to not get sucked into the "move fast and break things" or "documentation? f--k it." Nonetheless, probably makes a lot of sense for Facebook's mobile strategy.
Damn. I was going to use Parse for my app, but now I will not. What are some of the alternatives out there?
Whoa. This is pretty big news. This + Piecable + Facebook's huge push in mobile development recently = Facebook building a new, simpler development platform/environment for mobile apps? This speculation can be taken pretty far.
Boolean projections are fundamentally different than numeric ones.

Well obviously, the point was only to make it impossible so that students cheated.
Soon FB will monetize most of their APIs too. Example: Real-time access to all its social stream is going to be a paid usage API.
This made me curious too... What is the cost breakdown of a Tesla car? What part(s) do we need to improve to lower the price to that of a regular luxury car?
As a fellow young professional, in my opinion the only way to improve decision making is to increase the amount of information and experience that you have to draw from to make the decision. This can be first hand information and experience or second hand.

So work on gathering information before making a decision, surround yourself with people with more experience and/or different areas of expertise and take every opportunity to try and absorb their second hand experience that you can, and finally make decisions and learn from them. The more you have to draw from the more likely that you will be able to make the best decision.
Could this mean that Facebook is positioning itself as the AWS (in a very metaphoric sense) for mobile and expanding opportunities for the Facebook kapp ecosystem?

I understand that this is a new revenue stream for the company but I've never really seen the Facebook apps platform spawn "fully-fledged" apps other than those that boasted some form of basic Facebook integration. On the desktop at least, a Facebook app has always existed as a second-class citizen, being on a separate page that is segregated from the rest of the Facebook experience. Of course, you can argue that News Feed integration is one way to mitigate that, but from what I've seen, such integration is sparse and jarring - serving as an ad for the application that people on Facebook see.

What I actually did was read the article linked. If it's inaccurate shrug, I don't know, but a googling of "girl scout badge entomology" doesn't show much. If there are and they're meaningful, super, I'm pleased and 'part of the problem' is revoked.

As far as "science to dig out of cosmetics", that's rather a non-sense question. Yes, there is science, good, hard science. It's biology and it's chemistry, it's not "beauty".

Yeah, I get it, the 'idea' is we connect things they're interested in to science. Well, IMHO, the problem isn't getting the girls (or boys) who are into style and make-up to 'dig' science, the problem is encouraging and networking the girls who do dig science and math. (this is already done much better for boys, again IMO).
I'm a big fan of Parse even though I prefer Firebase as a developer. This is sad news because I think they were one company that was executing really well and would have been successful on their own. Even though Facebook and Parse say they are not going to shutdown the service we all know how that story goes.
Eventually! Good to know that someone would use it.

This doesn't surprise me in that it seems like a natural fit for Facebook, who has a Mobile Problem [tm].

As much as people fear Facebook becoming The Internet (in the AOL sense), Facebook is actually really late to this party.

Apple has a mobile OS, a content and payments ecosystem and a deeply integrated set of products.

Google has a mobile OS, GMail, a search engine, a burgeoning content ecosystem and its Maps/local properties.

Amazon has a content and payments ecosystem, a limited mobile presence (Kindle Fires basically, which are of course tablets not phones) and cloud infrastructure.

All of these things are (IMHO) pieces in technology's future. Facebook really is a one trick pony (although an 8000 pound pony if you want to stretch the metaphor).

It's why you saw them panic about Instagram (if a ~2 year old company with 13 employees is an existential threat then your position is, by definition, precarious).

It's why rumours of a Facebook Phone have circulated for a year or two (eg Project Spartan) and why Facebook launched Facebook Home. It's trying to get the benefits of having a mobile OS without actually developing one and building market share (ask Microsoft how hard that is).

Facebook's strength really is being a closed silo/platform for The Internet (or a version of it at least). So buying Parse makes perfect sense as they want to extend the reach and power of the Facebook platform.

Congrats to the Parse guys.

"It drains talent by offering smart people salaries that other industries can't afford."

Bullshit. The difference is that in finance (trading, at least), good technology is seen as a competitive advantage that makes a meaningful impact on P&L. When financial companies do well they tend to share the love in the form of cash bonuses. This is a strategy other industries could adopt but choose not to.

Also one other nit, there are only a few companies (the megabanks) that are big enough to have a government backstop if they blow up. There is a whole world of smaller outfits doing business without any such guarantee.
Welcoming Parse to Facebook
Lucky :).

But that's my point: It's not even first-come first-serve anymore, it's a server-load-powered lottery.
That really sucks. I mean it is great for the Parse team but I trust Facebook as far as I can throw Zuckerberg.
I think for this parallel to be valid he'd have to be eating McDonalds or what-have-you every day. The point is variety (mostly) ensures we get everything we need from somewhere. I think it's almost assured that in the long run 100% (or so) soylent will turn out to be more detrimental than even the 'average diets' out there. BTW, I'm kinduva healthy eating nut myself, but this just isn't 'healthy eating'.
You can totally do real-time raytracing. I wrote my first raytracer a couple of weeks ago — http://canonical.org/~kragen/sw/aspmisc/my-very-first-raytra... — and it gets about 4fps on simple scenes on my netbook, despite being the product of only a few hours of work. If you use a GPU and/or SSE and/or a faster CPU, you should easily hit full-motion video.

My netbook is probably half the speed of an iPad.

It would be fun to put together a custom OS-less AMI to raytrace partial frames in realtime on EC2. 20 instances spun up in a few hundred milliseconds could do pretty substantial real-time raytracing.
Ask HN: Time to fix the online ticket space. What would you do?
It's been an ongoing problem but these last few weeks have really focused my attention on it as a huge problem needing to be fixed.

Online ticket sales are absolutely broken. I'm not talking specific outlets, though they are broken for tons of other reasons, but the ability to resale tickets has been a huge pain as of late for many. Scalpers purchase their max tickets and turn around and put them up for sale at 10x the cost for concerts.

What really made me point this out now is this article on /.
http://apple.slashdot.org/story/13/04/25/2026214/wwdc-sells-out-in-2-minutes-ticket-on-ebay-45-minutes-later

What would be your solution here?

Mine would be simple - don't allow resale. Only allow the tickets purchased to be used by the person that originally purchased it. I can't help but think that applications like iOS' Passbook would be perfect for this. That way if you purchase a ticket, only YOU can use them. Even if you purchase many, then you have to be there to allow anyone entry.

I hate paying MORE for concerts these days but this solution would also provide an "insurance" at a nominal price that would allow a full refund if unused. Other sites already charge a ton for "service fees" so I'd happy purchase a ticket that only I could use and pay a little more to make sure I can get fully refunded if I don't go.

Thoughts? What's wrong with this solution? What would you do to fix this?

Soylent is certainly polarizing on HN, and pretty much everywhere else as well. This will only be resolved once it's widely available and people can confirm/contest Rob's results.

Personally, I'm very curious to give it a trial run. It certainly can't be any worse than what I eat now. Rob said it best:

Since when OCaml is semicolon-free? It not only has semicolons, single semicolon (;) means something different than double semicolon (;;). The former is used as an expression separator, like comma in Erlang, and the latter denotes the end of a top-level declaration, like period in Erlang. That's a pain while refactoring, but I can live with it. Anyway, that's just a style, nothing more, you can learn to love it or you can write a "transpiler", it's really a non-issue.
