When learning to program, my first major project was a feature-loaded N-back in C#/XNA. I crammed in every option I could think of. The game and code is available at http://workingmemoryworkout.codeplex.com, and it's worth noting that the inspiration came from Brain Workshop. (http://brainworkshop.sourceforge.net/)
They reached out to us on Monday asking if it was OK to be featured. I'm sure they'll be contacting more sites soon.

Great concept. Bandwidth cost savings are a big plus.
No evidence obviously. Just a silly notion that SSL would be a well encapsulated standalone user-space library, and inherently fairly portable. In hindsight, that was naïve from me.

This is precisely why The OpenPhoto Project exists. We're building a system where users give applications valet keys to their data.

Data ownership without portability is a moot point. Many services allow you to download a blob of your content but that's of little to no value for most users. What we really need (it's 2012 after-all) is a more thought out system where the user actually owns and controls their data and gives applications access to them.

This means multiple applications can leverage the same set of data and the user doesn't have to continue using any of them. Basically, there's no single point of failure in terms of data interoperability.

Currently, a user's Facebook content can be used by other services but for this to remain the user must keep their Facebook account open.

We're solving this problem by letting the user grant OpenPhoto software access to their photos. Most likely it's a bunch of photos that reside in their dropbox account but could also be an S3 bucket or box.net account once those become more consumer friendly.

In this particular instance we are talking about a mobile app hooked to web services, so it's in essence a web app with a mobile UI that was designed for mobile phones from the beginning.

Also, the ecosystem for mobile apps is very young, so the comparison is a little unfair. To the contrary, useful mobile apps have a lot of potential because these new generation smartphones are going to be in everybody's pocket in 1 or 2 years, permanently connected to the Internet, no matter if you're on your daily commute, drinking a coffee at Starbucks or visiting your parents.

To be fair, I wouldn't have paid 1 billion for Instagram, but then again I'm not rich yet.
Glad to have my company on there (http://codiqa.com/). Stripe has been great so far, I can't believe I ever used PayPal before.

My one desire for Stripe is more recurring subscription features, like notifying users of expired cards, sending invoices, receipts, etc. Initially I did that by hand but we've since paired it with Spreedly (http://spreedly.com/) which does all of that and it's a nice combo.

I would also like to disagree. In design, it's often the smallest details that make a particular design successful.

For example, Google Maps has a pixel or two of white around text. It's something you would never notice unless you looked for it, but it's part of the reason why gmaps have been so pleasant compared to something like MapQuest's maps.

Before 'Watergate' Could be Googled
I was originally going to link to the Mims memo, but I noticed that it had a few inaccuracies at the time of posting, so I opted for the Verge's recap - looks like the original's been updated (http://www.technologyreview.com/blog/mimssbits/27776/).

(Very excited about this whole thing, btw. Have been hearing rumors around town about a bunch of MSL folks moving up north to work on something very cool...have been dying to find out what that something cool is.)
After reading the blog post, I actually agree more with the 501 Developer manifesto. One year after graduating from college and landing my first professional job, I discovered that although I love programming, I love life a lot more. For me personally, it's all about maintaining a balance between my career and life.

In the end, no one dies wishing they worked more:

> "Write a technical blog"

I found that I enjoy writing a lot more when it is not about technical stuff. The few technical blog posts I write serve more as a mental bookmark for myself, that I can reference back to in the future.

> "Contribute to open source projects"

Honestly, I have yet to find an open source project that I feel passionate enough about to contribute to regularly outside of work. Until then, I'll continue focusing on my personal projects.

> "Attend user groups in your spare time"

I would rather spend time with friends & co-workers going out to happy hour or watching a good movie rather than discussing the frameworks/languages I use on a daily basis.

> "Mostly only read books about coding and productivity"

For the longest time, all I did was read technical selections on Safari Books Online. It got pretty monotonous after a while. I still read some technical books, but I would pick a great fantasy/fiction novel over a book on cross-browser CSS hacks any day.

> "Push to GitHub while sitting on the toilet"

That's insanitary IMO.

> "Are committed to maximum awesomeness at all times, or would have us believe it"

I'm not that awesome. Being part of the HN community has been an incredibly humbling and educational experience.

Ask HN: Any way of getting Pragmatic Bookshelf titles for less?
I was wondering if there was a way out there to legally get hold of Pragmatic Bookshelf titles for less.

As someone interested in Rails and programming in general, I love their books, and I find many of them super useful. I like them so much that I'd be ok with paying some kind of bulk fee, maybe 100-200 bucks, and have access to the entire catalog instead of paying for each title individually.

Does anything like that exist to this day? Do I have options?

It is actually like a blogging service like blogger.com or wordpress.com So if you want to post more than 140 chars on Twitter, you can login with your twitter account and publish your text, photos or videos.

Google is not right. The site has a lot of original content. Even Brazilian government authorities use richtweets.com to talk to their people. We have over 20k posts an these posts get a lot of comments, retweets and Facebook shares.
I really have to wonder, why is there no "peer to peer" social network? It seems ideally suited for this type of usage, and this would ensure that data is only in each node rather than on some central server. Does something exist like that already?
The scientific evidence for Dual N Back improving fluid intelligence is actually fairly weak as far as I can tell, see this critique and the other studies discussed:

http://www.gwern.net/DNB%20FAQ#criticism

My personal theory is that solving difficult math and programming problems is a better use of time than doing working memory training exercises. I'd guess that solving math and programming problems improve working memory just as fast as playing 'brain games', and they have the additional benefit of improving one's math and programming skill.

Of course, this is just a guess of mine that is unsupported by any experimental evidence.
It's the same problem with politics. The coverage is so much about the meta aspects of politics, the daily "he said, she said", not the actual policies that are being proposed. It's easier to employ people to write about the superficial horse races aspects, and because the subject matter is trivial, the audience is larger. It's profiting on the dilution of the media and everybody loses.
If that's really the case then there's no way Facebook is worth what (most) people think. Instagram launched in October 2010 and were acquired with only 13 employees. If a tiny company like that even has a chance to dent Facebook's market position then they are in an extremely precarious spot, IMHO.

More startups like Instagram are going to appear. No one can predict when or where but given the low barrier to entry, it's going to happen. If it costs Facebook $1B per "bullet" to kill them then they are going to run out of bullets.
I'm curious. Is this due to Shopify's reputation, or do you specifically seek out successful Kickstarter campaigns as potential customers?

This nine year old essay by pg is very well known: http://www.paulgraham.com/avg.html

Our hypothesis was that if we wrote our software in Lisp, we'd be able to get features done faster than our competitors, and also to do things in our software that they couldn't do. And because Lisp was so high-level, we wouldn't need a big development team, so our costs would be lower. If this were so, we could offer a better product for less money, and still make a profit. We would end up getting all the users, and our competitors would get none, and eventually go out of business. That was what we hoped would happen, anyway.
You and I aren't going to resolve the macro debate here -- there are better minds working on the job, and haven't gotten to the bottom of it.

But I wanted to take the opportunity to point out to other readers why they should be skeptical of the Keynesian prescription.

First, Keynes oversimplifies the system by assuming that everything is one big commodity. Everything is considered in terms of aggregate demand. The thing is, we don't have an aggregate demand problem in this recession: in aggregate, we're doing fine, and have been for some time. The problem is that we've got over-investment in some areas (like housing), and the need to shed that excess, and redirect it into sectors that have greater demand, is painful in any case. But the government's efforts to prop up housing costs is actually interfering with that process. And putting people to work on infrastructure projects as a stimulus doesn't do anything to help. Keynes's model assumes that demand (again, let me remind you that his terminology is "aggregate demand") is one homogeneous thing.

Second, inflation can't be used so effectively as a tool. Milton Friedman demonstrated pretty conclusively that such manipulations can't be effective, except in the very short term. The people aren't stupid, they can see that the government is inflating the currency, and then they take action to protect themselves from the losses that it would engender. The result is that the market will stymie the government's effort to benefit from inflation (not that the market will stop the inflation, but that it will interfere with any good that it might have done).

Further, inflation turns out to be a vehicle for redistributing wealth -- in the wrong direction. Before the inflationary pressure is felt, the first ones who get their hands on the new specie will enjoy its full value. And those people are the bankers. Do we want to make the banking sector the beneficiary of all that extra buying power?

I realize that my post is unclear, so I'll edit it. Yes, Earth -> LEO is by far the most challenging, but LEO -> Earth is far from free of pitfalls. Absent a space elevator, there seems to be no reasonable way to get the necessary components for a smelter to space, so any ore coming back would be coming back raw. Throwing bits of asteroid at the planet seems inefficient, to say the least.

Do you work at Facebook? :)

I think you're missing the point. Facebook doesn't have to hand out a text file with your name and a list of all your friends for it to be considered "selling your data".

It's considered "selling your data" when you go to an unrelated site and that site gives you customized content based on information you gave to Facebook.
What Ever Happened to Microsoft?
Firm Fixed Price is what the EADS did with the A400M. When governments kicked in, dictating engine suppliers, changing specs to fit all militaries involved...

well let's just say it did go well. Lesson to be learned: If you are in full ontrol of everything from scratch to delivery and have clear costumer specs you can do that.

If you are a quasi state-run business with political obligations serving multiple customers with different requirements, you better don't.
Right. If I still lived in Portland, Oregon, or even Eugene, I'd probably spend lots of time at Powell's or Smith Family and load up on real books. As it is, the selection of English language books here in Padova is fairly limited, and the other option, ordering from Amazon.co.uk is kind of slow too (despite reading, writing and speaking the language fluently, I don't enjoy reading in Italian as much as English for whatever reason, especially when the original is in English).

In that light, a device that lets me read books instantly is something of a minor miracle, and one of the best gadgets I have ever purchased.
"This is just mind blowing to me. These are endeavors normally left to nation states. There's something buried in here that I find fascinating."

One wonders if the rise of markets, global communication, etc., have rendered the nation state somewhat obsolete.

In theory, we still depend on our governments for things like public works, for ensuring peace, for promoting justice, and protecting personal property. These are things that we believe corporations would be ill-suited for.

And yet, in practice, at least in the United States and in the PIGS of Europe--we see that hey, holy shit, they've dropped the ball in a lot of cases. I'm willing to wager that we wouldn't be too much worse off with a different system.

Note: I take this position not in support of our new corporate overlords, but out of the necessity born from the realities of our government. If our government actually helped the public, actually had a legal system that worked justly and fairly, and actually did Good, I'd shun the amorality of the free market. But it doesn't, so I can't.

Would be better with some more data.

Ex: Overall literacy rates:

"In 2011, the National Institute for Literacy estimated that 47 percent of adults in Detroit, Michigan are "functionally illiterate," meaning they have trouble with reading, speaking, writing and computational skills."

So Detroit is not likely to be a hotspot for ereader sales.

No, I disagree two times on "relationship with target X is strong" and on "They don't feel like they can vouch for you". This may be the case be but must not necessarily, the motivation for such a behavior comes from my experience usually from somewhere else:

If one replies as I posted it's rather a strong sign that this person wants to control the relationship and the process as long as possible in order to particiipate—usually by getting some "advisory shares". We know that those shares should be given to people who made key intros (it's an unwritten law) but still it's cumbersome to deal with this kind of intromakers because they instantly show distrust to you (and more and more are getting like this)
At its heart, the internet is about information dissemination, in whatever form that information takes. Discovery has always been the issue, from link portals to message boards to search engines, it's finding information you're interested in. The current "social network" trends are another aspect of that discovery process. The difference being that an individual (or company) can more directly impact how the discovery is made and who makes it. This makes it more viable for an individual to provide information and it to be discovered. I think all of the 'mundane' applications of it you see are exploring different facets of the same thing. What we have is a specialization of one aspect of the internet (dissemination of personal information to a small network) and I think the next step will be the same for different categories of information. Not a "social network for code", but a platform for discovery that appropriately fits the niche. We then get q hierarchical discovery model where you search for where to find the information, and then search for the information. But we need all the boring steps in between to find the right model for each niche.
