Seems like a cool product but glasses are a thing of the past. People moved to using contacts because of the annoyance of glasses, and wearing them all day can actually hurt my ears and nose. And once we start taking them off and putting them in our pockets while not using them, they become a phone with less features.

I want something like this, maybe in a pair of contacts, but even contacts can be irritating. How about a genetically engineered eyeball?
What scares me is there is next to no choice on buying these, particularly if they are fast. There is an extreme advantage to people having easy access to information as it is presented in the video. Moreso than smartphones, it is a game changer.
Are you kidding about the iPad? It definitely suffers from lack of RAM. Almost every time you change tabs, it has to reload the page.

One quick note: I tried to select something on this page and nothing would happen. I finally figured out that I had to sign up for a service first.

Have you considered creating a bit of javascript that any site can embed on their site that would allow a visitor to annotate? This could be a really powerful channel for getting sign ups. Especially if you partner with some quality sites.

Also, have you considered making it anonymous to start like github:gist? It would be great to test it out without making a commitment of signing up. I.e., "Do I really have to sign up for something, before I even know if it will provide value to me?"
"Project Glass" Google's HUD

Great source!
(Seemingly) explosive growth garners much attention, it's human nature. Tech 'reporters' Techcrunch, VentureBeat, Mashable, etc, like a good story.

Maybe I'm naive, but it seems like there's always been this question mark over their model being non-sustainable, and to those who are aware of 37Signals hold them in much higher esteem.
They can measure the bags, but that does not guarantee that those bags end up in the box.

Also, there is a series on Discovery called "How it's made" (or so) I remember seeing one about Lego; they did measure the box.

That leaves open the risk of exchanging bags. Maybe, they are decreasing that by making sure that all bags hanging around when they are filling boxes for a particular set are different in weight?

I do not know whether that makes sense for huge sets, though. The variance in weight between boxes would, at some set size, outstrip the average size of a bag.
I find it ironic that a new e-currency designed to remove the need for cash or cumbersome online payment methods would reward it's challenge winners with probably the most cumbersome currency; gold bullion.

Anything that gets drivers' eyes back in the general direction of the road is a good thing. As a bonus, putting data at (perceived) infinity means that older drivers who have become farsighted will have less difficulty reading their speed, GPS directions, etc.

There has been at least one add-on HUD-type display for motorcycle helmets for a few years (http://www.gizmag.com/go/2430/). Last I read they weren't technically legal for road use in the US, not that I think anyone would be ticketing you for it.
That's not really true. You can store Bitcoin keys on paper with QR codes (or even just in your brain), and sign transactions on devices that have never touched the internet and never will. It's just the infrastructure that hasn't been built yet, but there is a lot of development going on to enable the average user to utilize these possibilities. That's not even mentioning multi-signature transaction support.

Ask HN: Payment Processing for marketplace
I'm working on a marketplace website which connects services providers and services seekers (much like eLance, oDesk etc). As in typical such a model, it escrows money from service seekers, makes match between providers and seekers and distributes money to providers when the job is done, while retaining its own commission.

I'm wondering which Payment Processing Provider will be best suited for my needs given that there will be many small amounts of collections as well as payments (ranging from ~$20 to $150). I also don't want to take the hassle of lot of manual admin overhead.

Stripe seems like a great choice only if you are doing only collections. Although PayPal makes receiving and sending money pretty easy, I've heard horrible stories about it.

Are there better options out there?
AVR behaves similarly. Branch instructions take 1 cycle if the condition is false, and 2 if the condition is true.

Next to no choice? You're saying people will just all want this by default?

I think most people will want to try this, myself included. But personally I draw the line here and I think many others will. I would never want to own a pair. This will be a niche product for those people who already use Bluetooth headsets, who are a minority.
True all that, but on the other hand Royal Mint - being a government agency - can't possibly be the source of a anonymous decentralized money initiative, can it? It'd be rather foolish to expect them to be. Nonetheless, this is a surprisingly innovative development to come from something as conservative as a money governance body.
You've nailed it with the last line: "simply becuase they lack the users and culture that instagram have built up."

It's all about content, and the content curators and contributors on Instagram are insanely passionate about their "art", and treat it as art with the same sort of engagement you would find among such groups (Burning Man, WoW Clans, etc.). Instagram embodies the Apple culture in that it has created an ecosystem. You don't just download Instagram because it's technically superior to other apps (it's not), but you join Instagram because it's a lifestyle.

Disclaimer: I was greatly addicted to Instagram for about 6 months, then moved on to the next big thing. Nevertheless, I was on it long enough to appreciate why it was so engaging.

Not having kids seems to be the first item in the list for that particular plan, so having a son disqualifies you!

Not to say that's a great plan. Having a life without kids wouldn't be a satisfying life for most people, and so if its a choice between kids and wealth, then most would choose kids.

I do think having kids early probably makes it much, much harder to become wealthy. My friends who had kids in their early 20's are generally poorer than my friends who waited until their 30's. I think a more realistic plan would be something that includes children, but waiting until you've had time to get some type of career started.
This comment: "Third, every time something goes wrong anywhere, a blizzard of new rules and procedures descends upon the school's obligations, lest that mishap recur anywhere else" is a lot like the part of The Other half of Artists Ship (http://paulgraham.com/artistsship.html) where pg says,

"Whenever someone in an organization proposes to add a new check, they should have to explain not just the benefit but the cost. No matter how bad a job they did of analyzing it, this meta-check would at least remind everyone there had to be a cost, and send them looking for it."
Lost Smart Phones and Human Nature
This reminds me of "Use the force Luke". I hope people don't start walking around with things like this all the time. I feel like in a 10 years people will walk around talking to themselves all the time and acting quite odd for today's standards ;p (I still find the people talking on handsfree cells phones weird at times.)
>“We’re sharing this information now because we want to start a conversation and learn from your valuable input,” the three employees wrote. “Please follow along as we share some of our ideas and stories. We’d love to hear yours, too. What would you like to see from Project Glass?”

Why would you ask that? This type of product is so different from what's available on the market that I doubt the Project Glass team would receive any type of suggestions they'd find useful.

That would be like Apple asking people "What do you want the iPhone to do?" before it was first released in 2007.

If you're creating the product, create it. Find the features you want it to have and research the features it needs to have. Asking the public "what do you want it to have" will not do anyone any favors. Decision by committee can be truly atrocious.
It's been a while, but IIRC:

It relies on having a third party that's trusted to be a reliable provider for value and knowing customers identities to punish double spenders (a Bank). (You can give up this requirement if you want to give up one of the other qualities I mentioned above, but those are different papers ;)

1. An account holder looking to spend creates a coin through a mutual process with the bank, which debits their account. The bank is unaware of the identity of the coin, but knows that it conforms to certain properties.

2. The coin is comprised of multiple parts P_1 - P_n, each of which has two pieces, P_i_1 and P_i_2. The account identity is encoded in the coin such that it is recoverable if and only if one has both P_i_1 and P_i_2 for any i.

3. To spend, for all i, a merchant requests either P_i_1 or P_i_2. (most likely based on the merchant's identity).

4. The merchant eventually turns these coin parts over to the bank, which credits their account. If the bank sees multiple spends of the same coin, only then can it put two corresponding pieces together and deduce the account holder's identity.

There are of course many details that force the parties to behave honestly at every step. The paper is somewhat old and I have no idea of further work (I'm not especially interested in protocols that require a bank or user identities). Main point being that if you do have a bank, designing protocols becomes much easier (Simple blind-signature tokens, for instance. These are anonymous but require online transactions).
This is a $1k option? Is there any reason why this couldn't be a relatively inexpensive after market product? I can pull information like speed etc out of the OBDII socket into my phone via a cheap bluetooth device. A projector can't be that expensive can it?
That's a pretty neat concept video, but of course it's more than likely just a well produced concept video. Hopefully the real thing can live up to it.

One thing I did think about after seeing the concept photos they have on the Google+ page (https://plus.google.com/111626127367496192147/posts) and in this NYT article, what about us poor people not gifted with 20/20 vision? But again they are probably just concept images and shouldn't really be taken as much more than that.

I want these glasses, but with lenses. Not just any lenses, I want lenses that have electronically-controlled, variable tint. Not only would I get the benefit of sunglasses, but the tint could be run up when I'm significantly engaged with my built-in display. Sort of an indicator to others to avoid the social annoyances witnessed in modern, overly discreet mobile phone Bluetooth headsets (and no, I don't mean black them out and blind me, nor do I mean to signal muggers as to my distraction in a shady part of town, though I do see the benefits of Peril Sensitive Sunglasses).
Make your computer noise free.
1) Two good incomes on the professional track.

I read a book called The Millionaire Next Door that described how getting married and staying married was one obvious way to boost wealth. Not only is divorce really expensive, but married people on average use less space per person than single people.

You can obviously construct scenarios where this isn't true—what if you marry a spendthrift?—but it was still a really interesting point.
Could a national currency integrate into the block-chain if they wanted to? For example, Canada could issue 'authorized' bitcoins, meaning the coin had to originate from an official source. And if the coin originated from an 'authorized' source, the value could be pegged at a certain price -- backed by the gov't? This way the currency could adopt the flexibility and convenience of bitcoin -- while retaining the ability to issue new currency.

Edit -- to clarify, a mint could purchase one coin, and peg the value of .00000001 of that coin to $1. Only transactions originating from this official coin would be treated as official currency.

It's the standard ChallengePost 404 page. What's wrong with it?
Actually it's kind of funny... I recently wrote a base64 encoder/decoder that makes use of native endian order to build 16-bit unsigned int based lookup tables that map to the correct byte sequence in memory regardless of native endianness.

Looking up a 16-bit int rather than 2 chars, and outputting as a 32-bit int rather than 4 chars yields a nice performance boost at the cost of possibly not being portable for some more esoteric architectures that don't have a 16 and 32-bit unsigned int type.

So while he's right that 99% of the time you shouldn't be fiddling with byte order, it still pays to know how to wield such a tool, and it's most definitely not just for compiler writers.
Hiring Hipster Software Developers, a Practical Guide
Well treating your users like guinea pigs can back fire. Look at Siri. There seems to be a lot of frustrated users, some even going as far as lawsuits. That model doesn't always work.
And that's why it's going to be hard for them to find success turning themselves around. Even if they came up with some killer new product, a lot of people would never know about it, and a lot of the ones that did would be skeptical because it's yahoo. When I worked there a couple years ago, they were very high on their brand's value. I'm not sure they should be. I think they might have more success launching (or buying) smaller, more self-contained sites with their own brands, similar to what they did with Flickr. (Of course, I have no idea if Flickr is actually a money maker for them.)

I work with many MBA colleagues and whenever they encounter an ugly, but effective (ie. converting) ad, they can never drop their egos to accept that such an ad can work. They just feel they cannot "stoop that low" to adopt these techniques.

They would often blindly push for "simplicity", "sparse text", "nice picture", and when these ads go out to market, they get absolutely crushed.

One of the tragedies of a big wealthy company is that marketers can continually go out with these crappy creatives that don't sell and there really is no big consequence. It is often written off as a "learning opportunity".

Whereas if you look at the ads of people whose lifeblood depends on selling their product, they may not be the most attractive ads, but the ads that persist over time tend to be effective (ie. they sell). These guys need to eat, and they can only afford to make stupid ineffective ads for so long before they starve! So there are definitely some practical lessons that can be learned from them. They often knowingly or unknowingly follow the principles of advertising legend David Ogilvy.

Their ads tend to hit on direct marketing best practices:

- headline states in plain language what the product does (ie. no MBA jargon/buzz words)

- headline also hooks the reader to read a bit more

- it is clear who the product is for

- copy combats any objections in reader's mind

- no distractions that divert reader from clicking the "Join Now" button

- contains customer testimonials reader can relate to (ie. social proof)

- gives reader enough information on the page to make a decision (ie. none of this sparse text BS if it doesn't make sense)
Apple drastically cuts feature scope early and often. The result is products that seem a little feature light to many technophiles and reviewers, yet sell like hotcakes to the real customers. How many companies could resist putting a camera in their hot new phone when they know there will be many negative comments on that exact point?

Apple is willing to wait and get it right in the next iteration.

They are doing a variant of Phase IV. The PMs are disciplined and upper management has the mindset of what we would hope for from sharp PMs.

Yes, that was strictly on OS X. I would think that Firefox and Safari would be rendering fonts in the same way, but Safari somehow looks better.

I last compared only a few days ago. When I get back home, I can try again and see if I can get more analytic about what the difference is, but, as I said, part of the problem with this kind of aesthetic/design judgement is that I don't have the vocabulary to analyze it.

It's just PR. You should take it with a grain of salt.

You do need more people to get more stuff done (i.e. taking additional risk to build new things). And you do need to lose people if you're short on money. There's really no way around it. You shouldn't fault companies for taking risks when they have the chance, our civilization would be pretty stagnant otherwise.

Well, LLVM+clang first needed to be built up to be suitable for such an integration (on and off Apple's dime).

I contrast the general situation with something like C# which is on record as being designed from scratch to have synergy with Visual Studio, not the other way round. This general quality shines through while developing with it.

For example, the wonderful LINQ language feature: Statically typed declarative operations on any data. You write these 'reversed' compared to SQL and in return that means each stage can be fully auto-completed.

Back in Obj-C land AKA Jurassic Park, code's full of things like 'IBAction' and 'IBOutlet' which are C macros #defined to void or whatever, just to help the tools out.

"The reactor, which resembles a large cylinder, is comprised of layers of advanced, ultra-high temperature insulation and ceramic materials. It measures roughly 2 feet by 3 feet and weighs a hefty 1,750 pounds.

The conical geometry of the reactor’ design uses gravity to feed zinc oxide powder (the reactant) into the system through 15 hoppers.."

(From TFA)
"...where it converts to a zinc vapor. At that point the vapor is reacted with water separately, which in turn produces hydrogen."

(Linked article)
"During testing, light concentrated to simulate the energy of 10,000 suns will be focused down into the reactor, sending the temperature within soaring to over 3,000 degrees Fahrenheit, nearly one-third the temperature of the sun’s surface."

...

One interesting feature of the reactor is that, in theory, the zinc oxide byproduct created during the reaction will be re-usable, making the project self-sustaining."
