Grouper Social Club seeks Rubyists
Hey HN,
We're looking for social hackers to join our engineering team.

Who are we?

We're a tiny team working to engineer the perfect night out with friends. What goes into that? So far we've built matching algorithms, an extensive A/B testing framework, customer service AI, and a real-time collaborative email client that's better than Gmail.

A few months ago, we shipped an iOS app that’s like Uber for your night out.

Then we open sourced the framework we used for it:
https://github.com/Grouper/FlatUIKit

Who are you?

You're a world-class developer with a track record of shipping excellent products. You're comfortable hosting a brown bag tech talk. You're a fearless explorer - If there's something you don't know how to do, you'll figure out the lowest cost path to understanding it.

I'd love to chat, just email me at tom@joingrouper.com

You can learn more at http://joingrouper.com/jobs

Cheers,
-Tom
Once you actually travel like this a lot you come to realize that changing clothes is basically optional. And as far as value per kilogram goes, smartphones are pretty much impossible to beat (well, maybe certain categories of medicine if you have some kind of condition, but otherwise I can't think of anything)
Cool idea, but what's actually a safer dense liquid? Maybe a very clever colloidal suspension.
Coin is awesome - but my mind is on fees
Or, the startup could save that insurance fee up each month, when the standard funds are gone, they declare EOL and burn through the savings doing maintenance while users migrate (of course, they'd burn through the extra, so the third-party does work better there).

The problem with a third-party is the complexity of handing over a full system and the fact the majority of startups fail early, i.e. the insurance fee would be much higher earlier in the life of the startup.
:( you're probably right, the universe always finds a way to ruin all the good ideas.
Yes! Mercury! Why didn't I think of that?
You can get up to DDR3-3000 from what I've seen but performance varies with application. The problem is that throughput isn't the only important metric, latency determined by the timing specs of the module are also very important. Higher throughput modules generally have significantly worse latency. For some applications, the throughput is far more important than latency but for many applications latency is just as important if not more important.

There are a few benchmarks at different speeds / latencies here: http://www.anandtech.com/show/7495/adata-xpg-v2-review-2400-...

It's just an old-timey filter that's hot right now, I don't think it's really particularly associated with online dating.
Lisp, so he knows how much fun programming can be before sinking back into the cesspool of more conventional languages.
:) well, technically they did use a web worker in their demo, so it's on a background thread, at least.
> China should abolish the death penalty.

Every country should, not only China. A murder is still a murder, no matter where and why it's been committed.
I'm starting to think there's a reason he doesn't want us to know the reason.
There's one in England that's mainly for tea kettles after major television events, like Eastenders. They're one of the power storage options that has the quickest ability to change their output.
Show HN: Tweets Machine is tracking #awsreinvent
Thanks! It will be interesting to see how much it will speed up as JS runtimes get faster, and as we are able to apply additional optimizations with Emscripten.

In particular, asm.js is explicitly disabled right now because of the need for memory growth. In the meantime, I'm planning on having a build with it enabled just to benchmark times on smaller files (where the growth is not needed).
Wouldn't you need to decrypt, on a jailbroken device, it to get something useful out of the assembly?
Or is that not needed for disassembling?
Thanks for following up; I'm not the perfect person to ask but it would make sense to allow all the metrics to be specified as sort criteria. Here are a few ideas:

* number of forks
* days since last commit
* ratio of open to closed issues
* days since commiter response to issue

Definitely copy the default / demo repo implemented by the OP too.
Looks pretty neat. I went to signup, but then noticed that they require commit access to my public repos. Why do you need this permission to integrate links to the code and similar features? I don't like giving out commit access unless absolutely necessary.
The problem with the "natural" approach is that then you have to deal with 1) natural increase in life expectancy, and 2) immigration.

Because of this, most European countries are still growing, albeit slowly. Japan has all but removed factor 2 and so its population is overall stable, but they're experiencing a slow shrinking of their working population (which brings a lot of economic problems).
You only need a large shaft if you construct the weight out of some material other than the matter from a neutron star.

I built a small app to cheat at Landlord (http://www.landlordgame.com) to check and buy venues from anywhere in the world. There was also a small script to get huge amount of coins (through faking twitter and facebook sharing).

After 10 days i was number one in the rankings. Scores and amounts of $ was so large that the iphone app was starting to bug... Of course it does not work anymore.

Isn't the Flash version using the same back end and API calls as the iOS version?
I'm waiting until Dropbox pulls a Twitter-move and disallows third party integration.
Well, good news for you, you can run the harp server on your own hosting! However, at that point I would just use the static site generator that I am accustomed to (Wintersmith).

Email and password. It's not really better to be fair

I can give a new service a disposable email address, I don't have a disposable Github/Facebook/Twitter/etc account. Not even a shred of a chance of me testing something if you're requesting anything other than the most basic of read-only permissions too
If you ever want to integrate real-time video chat as well, send us a note at vLine: https://vline.com. We actually have what we call a "GitHub identity provider" (https://vline.com/developer/docs/getting_started) that should make it really easy.

We used that to build GitTogether (https://gittogether.com), which is a similar concept to this: text chat and video chat with people you follow plus members of your teams and organizations.
killswitch, what's your username, i'll sort this out for you
That it's probably not a good measure of skill in any sense worth measuring, unless you think that 98.5% of the programmers worth hiring are men.

I don't see how those two points are related. A measure can be good or bad independent of who you choose to measure by it.

Github(not necessarily just having an account but actually looking at what they have done) is a good measure of skill because it allows you to see the person's work output. You know exactly what they contributed to a project and what type of work they are interested in and are familiar with.

Now just because it is a good measurement of skill doesn't mean that it is a good hiring filter. The two are similar but not the same thing. A good hiring filter filters for skill but doesn't filter for other attributes like race and gender. It is kind of like saying measuring how much weight a person can lift is a bad measure for determining a person's strength because we only measured white guys. It is a good measure of strength, just misapplied if you are trying to find the world's strongest person.
Express.js Fundamentals

But if you're using third party JS libraries and want to integrate with a Dart app? Seems necessary to still have to understand JS to integrate properly since you still have to know how those libraries' API works.

Edit: text overflow.
Ridiculous article. In essence they are saying "The press overreacts. The relief work is fine. If the press wouldn't report the problems then the relief effort would be better".

The press needs to shine the spotlight on the problems. Security is part of the relief process. That's typically provided by the state forces. The relief effort is broken if they can't reach the people who need help. We are talking human lives being lost. Every minute counts.

Microsoft's dystopian pitch for remote work
Yeah and the rent is too damn high too.

Compared to all the costs of marketing and doing business (like the landlord who'd rather charge $2X for rent and have 30% of the storefronts be idle), credit card fees are nothing. Storefronts, employees, shipping and advertising eat up much more of the cost of a purchase than does the credit card fees.
Nice! I did the same: https://github.com/bouk/rumble-solver

Where can I learn more about #1? Sounds very interesting.
I would love a port of Py-GNUTLS to the current GNUTLS. That is badly needed, as there have been major changes.

This is used by many interesting projects, like Blink (http://icanblink.com)
Yes, the part of the income that you consume would be taxed.

The point is that pretty much all of what megacorps make for their owners is not consumed - on that scale, houses, clothes and food are a small percentage, a rounding error. Don't think about what a small business owner is doing with his profits, think about what happens to profits of Walmart or Microsoft. Not about income of the 1%, but income of the 0.1% (which is the big part).

What is a billionaire doing with his money? A major part of it is reinvested to earn even more money - that can be done through the company; so the main feedback loop of rich-gets-richer is completely untaxed. Part of it is used to fund pet projects (like Virgin Galactic or 10,000 Year Clock project) or buy companies for control/prestige purposes - not taxed. Part of the wealth is simply accumulated to be given to your heirs - if there's no capital gains tax, would an inheritance tax stand? Part of that is used to buy political and social influence by funding parties and advertisement - not taxed. Part of that is used to buy prestige - ok, buying a fancy house to show off is taxed; but buying a major football club to show off isn't.

In essence, this means that the continuing concentration of wealth is untaxed, and you're taxing only the spending of wealth, which is something that actually redistributes wealth to the rest of society. This is not sustainable; that tax policy would fuel a rising and inescapable inequality. The society is better off if billionaires spend their wealth on fancy services (giving fancy income to the service providers), instead of owning all those service providers.
I thought the same at first. An OkCupid date isn't something I would expect to find here. The travel plan of buying a flight to one country and a flight back from another with no plans between, however, was fascinating and the type of thing I do enjoy finding on HN.
Computation intensive applications can be done in multithread by easily using web workers. It is been around for a long time. See the following site for a quick benchmark. [1]

It makes my felt lovely though ... have I introduced you to my friend the hare?
The theory is that seeing them close together, will cause an association in the (assumed male) reader's mind, between the qualities of the attractive sexy model and the product, so that when the reader sees the product in the future, he will be attracted to it on a subconscious level, and thus more likely to buy it ... or in other words, "sex sells".
I guess the first question is: why prevent people from doing this?

In my opinion, with games like this the ultimate goal of the server is to make sure one person doesn't ruin someone else's fun. Seems fine to let them ruin their own fun.
I have observed lot of people and the only people who I find to be happy or content are the ones with least ambition or those who create something (no matter the size of their creation). So my suggestion to you is focus your energy into creating something.
Other than the title and the beginning, I barely even noticed OkCupid in the story (maybe it was there, but it was not the part that interested me so I ignored it?)
Remember Draw Something? That game that was sold for $180 million to Zynga? I wrote an API library for that in Python https://github.com/bouk/drawsomething-api that allowed me to just add coins (the currency they sell for real money) through simple API calls.

Good times
We did use software escrow at my last company (hospital customers). I believe we just did source code hosting and it was roughly $1000 to set up and for the first X customers, and additional customers were a smaller additional fee. Given how aggressively SaaS services are priced these days, companies like Iron Mountain may have special pricing for SaaS. Getting a quote is the best way to go!

Also, if it's too expensive to do for everyone, you can of course offer it as a premium feature or a differentiator for an enterprise pricing tier.
Take something like the free the Square magstripe-to-audio converter, record a swipe. Clean it up and/or amplify it, connect the Square reader as headphone output, and blast the recording as loud as necessary to induce the read in a nearby swipe reader. Security-wise, "the magnetic field will generally fall off as the cube of the distance from the magnet".

China's total lack of an independent justice system and the resulting atrocities is not news, but bears repeating.

If you don't believe in universal human rights, there's probably nothing I can say to convince you otherwise. I guess the 20th century's bloody history didn't teach mankind very much, when people still look up to "thriving" nationalist states that build economic growth on the tortured flesh of their citizens.
I (like many people) have had this idea an energy storage mechanism. Unfortunately gravity batteries have an extremely low energy density for weight [1] or volume and so are only really a valid choice for something that operates at the scale of a hydroelectric dam.

Heat batteries make more sense for energy storage at a household level, whether it's heating or cooling. They're smaller, can require almost no maintenance and have a much higher energy density.

The display on the coin shows you the selected card, the expiration date and the last 4 digits of said card. So I believe your first point is moot, assuming the display stays active at all times or for a long enough duration that the cashier can get the last 4 digits as needed.
Oh, I realize how weird it is to fly on only one engine. I'm not rated for multi, but I've had some training.
Ah yes, the obligatory pessimistic/negative HN comment. I can think of some things an "ffmpeg.js" would be good for. Maybe not super-high-performance, but the masses don't care. Keep in mind ffmpeg does more than just videos. It processes images & audio files too; depending on what was --enabled during compile.

- Upload a short video-clip and turn it into a looping gif without the webapp's backend doing the work?

- Take an already existing looping gif and append/truncate it

- Add watermark

- Make a ringtone from your music-in-the-cloud?(This is an idea I've been thinking about for awhile, btw)

- It'd be kinda cool to see a program like, say, Adobe After Effects or Photoshop re-implemented in a browser. This happened: http://pixlr.com/editor/

- ffmpeg also supports streaming to twitch.tv; it's the backend to http://www.ffsplit.com/. What if you could stream straight from your browser? Some HTML5 canvas window streamed via "ffmpeg.js" to some other place? Access your webcam/microphone maybe?
You generally can buy flexible flights. It's a key thing to look for in mileage rewards programs, as it can let you use rewards miles more efficiently.
I don't see how that would make any sense. Why would they do that? To me, it seems like Dropbox wants to sell storage to people, the more things that plug into Dropbox, the more storage they sell.

Twitter made a bunch of moves to limit third party integration because they need to control the channel so they can sell ads to be displayed on the platform, and display promoted accounts and tweets.
Yeah, the problem is simply practical - digging a shaft like that and keeping it from filling with water is expensive.
I am not surprised at all. Same thing happened when I was away on vacation for three weeks. It definitely refreshes your mind. You start to realize on what to focus really focus on.

Thank God there's HackerNews, that way I don't have to spend my time browsing through 10 different blogs. Instead I rely that HN will deliver the best news value :).
Ask HN: Offer given as a cofounder
I'm looking for a startup opportunity in London. I was given an offer to be a startup cofounder. B2B app for finance market. The team will be me an a business guy. He is giving all the money for initial stuff (hardware/desks/software/hosting) as well as my salary. The offer is 24k (50-60% my market value) and 10% with standard vesting schedule. He is not going to take salary.

Risks:
- Don't know him very well
- He is not technical
- He's first motivation is to have a company that produce cash rather than sell
- He knows the market, but I don't
- Possible regulation or data issue (don't know if we can store it on Amazon)

Let's break it down. After 4 year I will have 10% change to have 3% of 20mŁ. That gives expected value of 60K in stock and 100k in salary which is 40k a year. Assuming I'm going to work 80h a week that gives me 20k a year for a risk free corporate job.

Is it a good deal? Should I ask for more? Maybe different deal when he's money will be company's liability? Should I get a layer to advise?
I'd say that most people wouldn't consider paying for more lives cheating. But that editing the communication between the game and the client is.

It would be like playing an arcade game. Putting in quarters for more lives isn't cheating. Creating a device that you can put in the quarter slot and pull out to reuse that triggers the game to think it's just got a quarter is.

It's curious.
As a condition of my employment, I had to sign a contract with my former employer that basically said since I was a software engineer with them, they owned all the software I wrote, even if I wrote it outside of my work hours. This obviously prevented me from working on any OSS.

Also please read my above comment. https://news.ycombinator.com/item?id=6740089 The article links to another article about why it favors white men.
Yes, I have the readme be the same everywhere... uff!

I think that is important a distinction between a full fork and a "I do a single fix" fork... but how?
RocksDB | A persistent key-value store for fast storage environments
Designing an API: Correctness, ease, then speed
What's the practical performance? Encoding a 24-minute episode with high quality seconds is a 6-hour overnight job (at least on my machine); if this is fast enough to finish in one night then ok, but I don't fancy leaving a browser running for a week.
What is the real story behind Samsung and Tizen?
I appreciate the feedback! I think if you talk to business owners, you'll find that's not true. It's the second highest store-leve cost for most businesses, including Big Box.

I, for example, was running a monthly ramen-box business charging $20 per month per box. My costs were:

Ramen: $7
Shipping: $5
Credit Card fees: $1.20

That means without CC fees, my profit went from $8 a box to $6.80. That's a 15% reduction on my profit, and that's without labor costs factored in. With labor factored in, that's my whole profit, 100%. Sure I could have raised the price or whatever, but there's always options: my point is you can see how destructive that can be.
Or there's increased pressure on people to generalize solutions so that they can release them on their own as github projects, benefitting everybody.
Whether lightweight abstractions exist is moot. The point of the grandparent was that sockets are portable. If you're going to use an extra library besides pure sockets anyway then why is that any better compared to using ZMQ?
Except in a live coding exercise most people are trying to be efficient or 'to it right' and paying attention to what they are doing and how.

I realize this is anecdotal, but 95% of the public code in my git repo is stuff I did as fun. I didn't care about being right, or care about memory issues or being thread safe or anything other than 'I wonder if...'

In that instance, and I suspect a lot of other people public where they aren't contributing to something using the repo code as a talking point is counter-productive.

Why did I do it that way? Because I wanted to see what would happen.
The travel idea is fascinating to me. Lately I have been really interested in taking a month off work and hitting the Andean countries in South America. Start in Colombia, hit Ecuador, Peru, Bolivia, Paraguay, Chile, and Argentina. Brazil and Uruguay if there is time. Adding this to it would give me much more flexibility and encourage me to be spontaneous. I probably wouldn't go as far as they do with no stuff though. I'd bring clothes and my MacBook Air at least.
Lessons I have learned in my first 80 years
FoodSnap

You take a photo of everything you eat. The app organizes the photos by day. The daily digest view shows you everything you ate for that day.

This could be used for dieting (perhaps looking at everything you ate that day before going to sleep helps you realize how much you actually ate, as opposed to not thinking about it when you're munching bite by bite).

This could be used for personal discovery (probably everything you eat has an effect. You can start to become more vigilant of your food patterns by keeping a visual journal).

This could be used for medical purposes (need to monitor what you're eating, etc).

Anyhow, probably v1 is very simple. Version A might involve image detections. Version B might just get some mechanical turks to identify what you ate to make the visual data textual. Version C might let you make quick notes after you take the photo.

Brainstorm to where the app is something people pay to download or use.

This is how I do most of my holidays. I don't have the time to plan holidays in detail, so typically book flights to/from two different places, and go.

The other option is that I jump in the car and drive until I hit desert, jungle, snow, or whatever takes my fancy.
