That article is way too vague to be of any use. There are a handful of small studies that show less-than-optimal results for pre-exercise stretching when we're talking about running.

Soccer, basketball, dancing, weight lifting, rock climbing, none of these have anything to do with those results, and you should talk to people who have been doing the activity for years about how to be healthy, not about.com.

The concept has merit IMO, but I'm not sure about the current implementation. I assume (perhaps wrongly) that they are going to establish relationships with merchants ... or maybe they're building something that FB or Groupon can plugin to their network of merchants.

When I need to send a list-minute gift or a gift to someone out of town, I almost always email an Amazon gift card. And I can't see (yet) why I'd use this instead.

I would also be interested in something like this.
Having built websites in Ruby and Python, I've found Clojure to hold its own in terms of productivity. Clojure's library ecosystem is healthy and growing and you can tap into the battle-tested Java frameworks with ease.

Saying that Asynchronous I/O and multiprocessing solves 80% of the problems is hand-waving away the complexity such approaches might add to a project. Clojure simply gives you more and better tools then Ruby and Python currently do for dealing with concurrency.

You might not bet your business on Clojure, but certainly other people have for a couple years now and they don't seem to take issue with it.

EDIT: removed the defensive bit. My experience, as this thread shows, is that people get touchy about the limitations of the GIL.
"While there are enough programmers that know PHP (which is clearly a plus) there’s just not enough sex going on here. As with Perl, PHP really wasn’t in the loop."

How is that a valid argument? "not enough sex going on here" ... if you choose a language because it's sexy and not because of its utility, you are making a poor business decision.

Digg spent a long time revamping their system in new languages and on new databases and look how that turned out (not that the languages were the core part of their failure, but still)
It's a reasonable point, but we don't yet know whether there will be LTE phones that work on both AT&T and Verizon, let alone when roaming abroad.

Review my startup Munchery, solving "What's for dinner?"
Link to sign up: http://gomunchery.com/via/yc

We want to help busy people not having to stress about planning for dinner on a daily basis.

We are going with the less-is-more approach: instead of having to make decisions about what to order from a menu, chefs decide for you.

You subscribe to chefs and specify the number of meals for the days of the week you want (you can change or cancel anytime). Each chef has a fixed price per meal. Once subscribed, the chef selects the ingredients, decides the menu, prepares and delivers the meals to your home/office.

We are still making a lot of enhancements, but the gist of it is there and you can definitely place a subscription order. To encourage you to give us a test run, we are giving out $10 credit for new sign-ups (until we go broke!)

We lined up a few independent chefs and restaurants to start. Just launched our beta this past Friday and would love to get your feedback.

Thank you

Exodus international's "Gay Cure" app sucks dick
From the article:
“If patents are too easy to invalidate, the risk of invalidation – as well as the prospect that every infringement suit will be met with a burdensome validity challenge – may raise the cost of enforcing a patent to the point where the expected value of the patent cannot justify the outlays entvation (sic),” the government’s brief states.

“By allowing a lay jury to second-guess the PTO’s judgment even in close cases,” it continues, “the preponderance standard would diminish the expected value of patents and would reduce future inventors’ incentives to innovate and to disclose their inventions to the public.”

This seems like one of the best steps toward ending SW patents. If you can't knock them off the books, effectively make them toothless. Of course the US government is strongly in favor of the status quo.
"As a nation, we spend more one education than the military..."

You say that as if it's a bad thing. I spent four years in the military and can tell you that there's a lot of waste there. Your last sentence could very easily be applied to the military, or at least to military personnel.

I think a better way to think about teachers might be as force multipliers. There are parts of teaching that can be relegated to technology, but there are other (arguably more important) parts that probably can't or won't be for a long time, and KA seems like a great way to free up those resources for uses that are most effective.
Stating an opinion is not getting defensive.
You can do whatever floats your boat.

EDIT: RE: Don't take me wrong, I sometimes hate the limitations that the GIL brings.

I'm continually looking at alternative implementations, like Pypy or Rubinius or JRuby, or other languages, like Haskell or Clojure, but then I end up doing a lot of yak shaving and nothing gets done.

We do give you the model's measurements but they don't necessarily mean much. The stylists for the models will pin the clothes to fit well so the pictures look good.

People who are models generally fall within a certain range of sizes, but it's still impossible to predict perfectly what will fit them, and you might not even have all the sizes available.

Ask HN: Anyone interested in a private Ruby gem hosting service?
As part of a project I'm working on, I've built a service to host my custom Ruby gems. Many of them are proprietary and will not be released via RubyGems.org, but some are just tweaks I've made by forking projects on Github that have not been pulled yet. The service makes my deploying story much simpler.

At this point, it's in "single player mode" but if there is interest in the community, I can hack it up for everyone else. Either reply to this thread and/or leave your email here if you're interested in updates: http://www.gemfury.com/

Question: which major carrier(s) are not known (or known not) to do this? T-Mobile supposedly had little evidence against them, but they're being assimilated.
Here's one I wrote earlier for British YC companies with a few updates:

Cambridge: Immad Ahkund (Heyzap), Jude Gomila (Heyzap), Rahul Vohra (Rapportive), Martin Kleppman (Rapportive), Sam Stokes (Rapportive), Ian Hogarth (SongKick), Pete Smith (SongKick), Michelle You (SongKick)

Imperial: Tim Davey (SnapTalent), Sumon Sadhu (SnapTalent), Niall Smart (Echodio), Nathan Chong (NewsLabs), Jof Arnold (FitFu)

Oxford: Peter Nixey (Clickpass), Harjeet Tagger (Auctomatic), Kulveer Taggar (Auctomatic)

Bristol: Tom Riley (Fabricly)

LSE: Ari Helgason (Fabricly)

Southampton: Benjie Gillam (FitFu)

Kent: Mike Laming (Propable)

Anglia Ruskin University: Peter Clark (Still in stealth?)

Newcastle-upon-tyne: Einar Vollset (ReMail)

No university: Michael Ossareh (HeySan)

It's not comprehensive and I wrote it from memory, but it's indicative that there is some level of correlation (Oxford, Cambridge, Imperial, Bristol and LSE are all generally ranked as "top-tier" universities).

For personal experience I'd say Cambridge graduates are far more likely to found startups than those from other universities. I was at Cambridge StartupWeekend a week or so ago and there were probably 20-30 students from Cambridge university there.
The best analogy I've heard of Twitter is it's like I were to stand on my balcony and shout at the crowd below.

API is the future of marketing
It's interesting that Google is the most desirable employer for the general professional population (which doesn't have the skills to work there) while simultaneously being perceived as suffering from a (no doubt exaggerated) brain drain by their desired employee demographic.

My guess is that this is largely a trickle down effect of the legendary stories about life as a Google employee that circulated in tech circles 7-8 years ago.
I've been learning to weld (using the TIG process) and it does have that cool mixture of being able to produce amazing, strong physical objects and also being Dark Magick for the average person. The TIG process in particular is a mixture of science and art that makes you feel like a wizard when you start getting good at it.

Watching a professional bricklayer work is pretty mesmerizing. The really good ones achieve this rhythmic action where they seem to manage to quickly and accurately place and set every brick while taking advantage of inertia of the moving bricks to expend the minimum physical energy possible.

I don't think there are any ditchdiggers left in the united states though, only bobcat or backhoe operators.
Pretty cool to see a screenshot of my app, Zite. Feel free to ask any question or suggest areas to improve!
Can't speak to YC's experience, but I attended a historically black college/university (referred to as HBCUs) and knew a number of top-notch African-American CS students/hackers while I was there.

At one point, out of 7 or 8 undergrads in a research group I was with, more than half had completed PhDs and I think the rest of us (I was the lone white student in the group) had picked up MS degrees.

A number of the higher-quality students from this institution were heavily recruited by big corps with eyes on increasing minority hires and diversity rates.

What I mostly know is that successful CS students from this institution had their choice of top-notch careers or academic research opportunities. As a school (and my general region), not much emphasis was placed on entrepreneurship. Maybe both facts come into play with startup culture today.
I know - Gazelle quotes $175 for the phone. But the battery was draining quite a bit faster than usual, it was rooted and I didn't wanted to sell it to someone only to get it back or have them ask it for less.
I know it's hard to build out into other markets with a biz model like this, but would totally give you money for something like this in South Florida. :) (And could even hook you up with a few local chefs that I've tried this with on a one-on-one basis.)

The biggest problem I've had solving this on my own is agreeing on the menu ahead of time so I don't get blindsided with the bill afterward. Would love to see how you solve this without signing up.

I agree. I'm doing it myself also, otherwise it would be impossible to develop for android. But you need to test your application on different screen sizes, dpi etc.
Or you can buy loads of different phones to test on them all.

Ask HN: is there any distributed pub sub framework built using node.js?
I came across following two link where the authors claim to have built a pub sub framework. But I see that they are single server based. All publishers and subscribers are talking to one same server.

I need something where there are multiple servers arranged in different kind of topologies.

Is there any such thing already ?
The best way of thinking about it that I've found: Did Flash games kill the PC gaming market? No. Will iOS/Android/etc games kill console games? No. Perhaps they'll encroach on the handheld market (PSP, 3DS), but I don't think they've got the same "depth" that most console and PC games do.

Don't get me wrong, it's a lucrative market to be in, and it seems much easier to break into for most developers (although indie PC gaming is also a good size scene) than traditional console/handheld development. I just really, really am not convinced that they'll kill off console games. I've never heard someone who's actually a more hardcore "gamer" entertain the notion, and that makes me think that most people making these claims don't understand the market for them whatsoever.
I though hardcore FPS players mostly uses high-end PCs rather than consoles.
Love it! I would really like to use this service right now. I don't really mind shopping, but I can't visualise the clothes with something else. If I can find everything in one place, that's a little better, but I'm completely lost if I buy a shirt that I like and discover it doesn't really look that good with what I already have.

I'm not sure if I would actually buy online, but asking me questions and presenting with an idea what to buy would be a great help. I tend to use the people working in the shop for this - since they usually wear the clothes available in the shop, I end up with "I want to buy the stuff you're wearing" (or some less creepy alternative) when I spot someone whose style is ok.

I've seen plenty of people on HN tout Khan Academy as the awaited usurpation of the education system.

Many also call it "the future of education" in a vein that it's meant to replace parts of the educational system.

I think Khan Academy is going to do wonders for the American K-12, if teachers are made aware of its advantages.
France Fines Google Over Street-View Wi-Fi Data Collection
It's not about the product, it's about the passion behind it. I'm a classic example of this. I have some great ideas, but so far I always lack the attention span to see them through. And, sadly, it seems as I get older my projects end up dead a lot sooner than they used to sigh or maybe I'm just gathering up experience points for when the big day comes :)
And what is the point of negotiating if you know there is just no way you will one this one :)
We're using Riak to store forms that can have varying schemas as JSON. That and the no-single-point-of-failure were two of the big draws.
I didn't mean to suggest it's bad that education is bigger than the military, I was merely trying to describe the scale of our spending. The military is a popular example of a a big wasteful government agency, so I thought a comparison was illustrative.

I spent four years in the military and can tell you that there's a lot of waste there. Your last sentence could very easily be applied to the military, or at least to military personnel.

I'd love to reduce spending in the military as well. If a manufacturer of military robots said "we aren't trying to replace soldiers", my first question would be "why not?"
Agreed. Monetizing dress.me as a preferred associate of clothing sites, or as a walled garden market where only you can offer select deals, would be far more palatable. I am also in your target demographic, but all I want is an algorithm that tells me when polka dots and stripes don't match.

We think it was because of the economic crisis. The restaurant sector was hit pretty hard and that probably caused a lot of companies to stop advertising.

The revenue is now back to it's old levels, but it stayed that way for 6-7 months.

We started a program that allowed restaurants to advertise directly with us. Made it very easy to try by not having any contracts and being a lot cheaper than our competitors. We got someone to do sales on a commission-only basis. He was so good (~ 70% of the restaurants he calls become a customer) that he is now a partner.

We also added affiliate links to sites where you can order food online, make reservations, etc.
Monopolies prevent competition from entering the market (by definition) by building barriers to entry. AT&T is not a monopoly, people like to throw that word out whenever a company does something like this. What Intel did to AMD is a good example of a company using a monopoly position to prevent competition.

Very true, education is paid for primarily at the state and local level. The comparison to the federal deficit was mainly for the purposes of an order of magnitude. I've edited my post to clarify this.
