But there is a crisis of innovation. The hyperloop is not a good example of it, because all the reasons abalone mentions.

Two examples:

1.Talk to people in the medical device community. There are plenty of good ideas , but they are hard to build and it's hard to raise money.[2]

2.Robotics: VC investments totaled in only $190 million in 2012[1] for a technology that is quite highly developed.

[1]http://www.hizook.com/blog/2013/06/10/venture-capital-vc-fun...

[2]This is partly due to the difficulty of writing software in this highly regulated environment. Seems like some pre approved platform should help here.
It's pretty annoying because all I want is a debit card, I don't want a credit card but my bank forced me this kind of dual card.
Is that any different for men? I mean, I may buy the odd (relatively cheap) geek gadget, but most of my tech spending is pretty similar to that of my wife.

Yet there is plenty of tech advertising aimed at me.
Here’s What No Bueno Really Means
PDF is just a common format used when sharing documents for viewing, like you said. No deeper meaning to it than that.

This tool can convert many file types to PDF without the need for acrobat, office, etc. Basically, this just costs $20 and those cost $200. It's just a small, one trick pony piece of software.
Thanks, I've been looking for a tool like this.
The PCI people are going to have a conniption when they see this.

> Australia is a regulated market that abolishes the high interchange fees that power the reward programs in the U.S. This is specifically for the U.S. market.

Obviously, Australia is not free™ enough.
That's why the majority of them stay at home. For some reason, the grocery stores, when doing self-checkout and such, don't have email input or phone number. :(

EDIT: I should add that the main grocery store I shop at, you scan your card when you enter and are given a wand to checkout your groceries as you add them to the bag.
mmmm. So ghostery is reporting blocking the following:

* Facebook Connect - Widgets
* Google Analytics - Analytics
* New Relic - Analytics
* Typekit by Adobe - Widgets

Are you saying the website _needs_ one of all the above to display some webgl content ? Or something else is being blocked by this extension?

I have an airlines reward card, a business card, and an ATM card. I don't think there's a way to combine the airlines reward with the ATM, even though they are from the same bank.
Selling Your First eBook
An eBook can become a very powerful asset for your online business. Here are some tips and tricks to help you promote it and generate commissions.
There's no story in this article. It is just a chronology of events designed to show off their hipster muscles.
Yes they are separate, debit uses my bank account directly and credit is invoiced every month separately.

The selection process is very simple, you just put your card into the machine (almost all the cards nowadays are chip based nowadays but there is also a magnetic reader usually on the right), something like this

http://data.talka.com/files/Yomnani.JPG

then the machine shows amount and you select

1) Credit

2) Debit

Then it asks for pin and that's it.
I don't currently have a car, so my ability to go to Costco is usually a very impromptu thing.
"See ID" is also a signature if done own handed. I've seen a court decision to the effect that you can declare your signature anything you write. Important is if _you_ accept it as such later on.
I'm going to compile up LMDB and bench it on a 96GB DL380g8 with quad 3TB ioDrive-2s. Should be interesting to see how various database sizes play out, and what the write amp looks like. I am not seeing much about LMDB's NUMA awareness -- guess I need to keep digging.
I remember scratching my head trying to buy ticket from automated ticketing machine in Amsterdam Centraal because the machine required chipped card only and none of my US cards that I carried had one (not to mention the error was not clear enough and I was trying all my cards in different orientation).
If it is based on DDR3, video cards that use it are significantly faster than the same card that uses DDR3
Nice tip (not sure it works, but worth a try), but why not post a direct link to Youtube video? The linked site is a PITA with NoScript and Ghostery.
I find this risky on the part of Renault. We still have the ENAC principle ( http://en.wikipedia.org/wiki/Exceptio_non_adimpleti_contract... ). When Renault locks the electric car, they are reneging on their contractual obligations. So given that they want to recover the money, how will that work ? In court you can say "I'm not paying for (a) the period that the car was disabled, ever (b) nor am I paying anything until the car is re-enabled", and that's a defensible position. Given that the car costs exactly the same (in loan repayments) to Renault, whether it's driving or locked down, this seems beyond stupid. I wonder who their legal advisor is.

Reneging on contractual obligations is something you should only ever do if you're not expecting any payments anymore.

(Of course this would be the situation in Northwest Europe, I'm not sure how this works in the US, so YMMV. And of course, you can bet it's unlikely in the extreme a collection agency will see it like this). This does not constitute legal advice, and I am especially not advising anyone to do anything. I am just voicing a concern. Contact a lawyer before you do anything (there is free legal representation for people having trouble with payments to financial institutions in most locations, use it).
I can almost hear the indie music and fixie bike bell ring.
Chip and sig was accepted everywhere I went in Europe this year. I have a European bank issuer though.
I wonder if in 30 years people will be showing off their photo albums to which their kids will wonder why aside from the images not being 3d. That the photos have had detail purposely brushed out by means of superficial Instagram filters.
Consumers vs. App Developers: The Pricing Problem
My JS1K Demo – The Making Of
You're right. I did find it interesting to contemplate though, and has encouraged me to reconsider my requirements next time I travel, or just in life.
I had a girl fly from London to Spain for our second date, the day after our first, whilst I was on holiday with my at-the-time-ex-girlfriend.

Crazy stuff can happen!
Really excited for the launch of My Yoga Pro. This type of yoga access is just what the world needs! Cannot wait!!
Minimalist travel apparently includes an iPhone and an iPad mini these days. So much for getting away from it all!
The writing really is fantastic, the story compelling and unique, and the take-away completely expected. How could you not find yourself more focused, more present, more enrapt by the lands and peoples surrounding you, with nothing to distract you but the clothes on your back!

Modern marketing machines aside, I think the human condition really lends itself to exploring the world like this. There must be some base instinct which tends to support a high level of empathy and respect for the courageous and peaceful strangers who throw themselves into a foreign culture like this. Obviously some tribes don't invite strangers so easily, but often the people you think would be most hostile are the ones that welcome you the warmest.

One thing I'm mildly curious about, when asked, did they say they were Canadian? ;-)

Kudos to Clara and Jeff, and thanks for sharing your story with us.

EDIT: For those harping on them carrying an iPhone/iPad, let me just say this; feel free to comment about how your own similar experience was further enhanced by also unplugging. In the meantime, I'm impressed with anyone who can take such a large bet on the chivalry of strangers in a foreign land and come out so much better for it. Personally I think carrying an iPhone is orthogonal, because it's a useful planning and safety tool which does little to dampen the experience a trip like this can bring.
SSDs really are 1000x faster at random writes (~200,000 iops vs ~200 iops)
There was a time when talking to others in a crowded room filled me with fear to the extend that words flowed out of my mouth in ways that does not make any sense even to myself. I spoke gibberish and if you had the misfortune of talking to me, you would probably find an excuse to get away.
I hated the idea of going to social events. At every event, I felt that I was the stupidest person in the room and that nobody would want to talk to me. Meeting people seemed like a waste of time.

One day, something snapped. I figured that instead of wasting time at social events, I might as well learn something. I reflected on my social experiences and realized that because of my inherent fear of being looked down upon, I had the habit of pretending to understand things that in reality I had no clue. So I made it a point to speak a little as possible and instead focus on listening and always ask questions if I did not understand something.

I always made it a point to be asking questions and most importantly, never pretending to understand something I don't. Conversations usually flows like this: What do you do? What exactly does that mean? Big data? How big? How is big data different from normal data? ...

Gradually, I started to understand what people are actually saying. I started to feel the wide spectrum of work that people do. I started to internalize differing opinions within similar industries and then voicing these opinions to others in similar fields. I started to take sides and participate in debates. Conversations became more intelligent and social events transformed into a heaven for intellectual stimulation.

Like reading Hacker News in the middle of the night, socializing can become addicting. There is so much knowledge out there and every time I go out I learn something new. If there was one lesson I learned throughout my transformation, it would be to focus on listening and understanding others.
Is this the reason for your observation that LMDB is oriented towards read workloads?

I can see how the extra code locking/concurrency code would expand the library size out of the CPU cache, though.
Indeed. There were 3 of the largest wars in history during the 20th century (WWI, WWII, and the Cold War). That's going to necessarily skew the statistics on development of technology in recent history.
I love how an iPhone was deemed more essential than a change of clothes.
Well if you can donate your time and want to do something different, meaningful and help build a product from the ground up which will save lives of some of the most vulnerable people in the world every day? - come and join us!

An early stage human rights start-up (the founder has just spent five years at another human rights startup which he helped setup and is now a market leader) in East London (still in the fun garage shed stage!), is looking for a mobile app developer or CTO. (Also people with associated skills such as LAMP, UI/UX, HTML5, etc would be great)

The start-up focuses on addressing a significant gap in the security of human rights organisations, journalists and activists - through the use of a web and mobile application. It builds on years of cutting-edge security operations in this field.

With the product features and business plan nearly complete we are looking for the right person to bring us to the next technical stage. Ideally you will be in London but remote working is also a possibility.

Insta spotted bug. Toggling 'Show brands' the number increases every time.
1. reasoning from first principles is a really cool, powerful and awfully difficult. Most importantly, it forces you to consider what the question actually is (see Douglas Adams).

2. the BOM cost is an interesting perspective, but is a terrible example of the above, because it doesn't go back to what the problem really is (energy), and also excludes every solution except batteries made of the same materials, and therefore likely based on the same principles.

3. the analogy to BOM for software is information (what do we know? what do we want?). While this is closer to true first principles than BOM, it assumes the problem statement, and thus precludes reconceptualization - changing the specification, changing the requirements, changing the context.

BTW describing a startup as the "x of y" is a way to communicate it succinctly, and not necessarily what it really is. It's ad copy.
I think this definitely comes with experience, and therefore confidence. I own up to not knowing things all the time, but I doubt I would've four or five years ago. It just becomes easier when you're confident in what it is you do know.
Hold on, so you're arguing that DARPA "rescuing US industry from Japanese competition" is proof that the technology absolutely required government investment to advance it?

Need I really demonstrate the fault in that logic?

Heh ... I've flown for dates at least 3-4 times. Seemed romantic at that time. None of them worked out and I blew a lot of cash. But it makes for some interesting memories :)
You suck. Can I borrow $700 to pay a PR firm to promote my game?

I'm hoping to get my kids off of welfare someday.
I did something similar albeit not so cool and without the intent of dating but with a backpack. Hiked and Hitchhiked a few weeks through Europe with a girl. We met through a "looking for hitchhiking partner" forum. It was tremendous fun. We almost had no money and no iSomething but met a lot of nice people and got around very quickly. We also showered and changed clothes every few days. Smelling like shit complicates things. Hitchhiking is far easier if you look and smell "normal".

I remember driving a BMW from the 7 series into the sunset heading to the atlantic ocean in france. I have the credit card of the car owner next to me (for the toll stations) as he is sleeping and we are listening to his favorite french chansons. He was a banker not much older than me. This connected feeling and trust is priceless and I'm really flabbergasted every time it works. There is a longing in the people you meet on your way and a longing in yourself. Nothing beats someone who stops and offers you ride after you were stuck for 6 hours in a godless place surrounded by refuges who are trying to enter great Britain in the back of trucks that cross the border. And you suddenly realize how important that passport in your pocket is. And how lucky and privileged you are and what desperation does to people. I don't know. It changed my perspective on a lot of things.

If you are careful with your money and avoid tourist areas and research cheap spots before going to big cities (more expensive if you don't know where to live on the cheap) you can travel for 4 weeks for 500 to 1000€ in western europe using only a tent and a small backpack. In eastern europe it is probably cheaper. We also went to restaurants quite often - so we were quite wasteful.

But if I would do it next year again I'd also take a smartphone with me. There is the great hitchwiki.org and Couchsurfing and other internet services would help me save money and time. This was in 2007.
What's interesting is that there's now a societal expectation to have one child per couple, so the birth rate recovery will be spread across many years or decades.

The economist has published several excellent articles on the modern impact of the policy.

write a story!
I don't understand that at all. Suppose the shareholders' dreams happen and Facebook starts earning enough to make dividend payments that repay the value of the stock in, say, 10 years.

What's to stop Zuckerberg from just directly diluting every other shareholder ?

(and of course, that's exactly what probably happens right now, because Zuckerberg gets more stock options yearly than anyone else, so his voting power does not dilute over time)

Please don't see this as an attack on Facebook. It's hardly alone in doing this. And I do agree that Zuckerberg is probably a lot more qualified to run Facebook than any (set of) investors. Still, why take the risk that he might "cheat" ? Why are these shares selling ?
It's pretty funny, because all of these except a couple (which I noted) are pretty necessary and no work around. It's like people commenting to this thread didn't even read what I originally wrote. Anyway, I'm adding here a list of more cards that stay at home that I occasionally use.

Also, I could elaborate more on why certain cards need to be with me, but I thought things like Costo & Zip Car were pretty obvious.

So the list of home cards:

* MTA Metro Card for when I'm in NYC.

* USA Cycling license for racing (they have an app now that I can use when I show up at races)

* Best Buy Rewards card (I know, I know....but they can look up by my email)

* Several complimentary coffee cards for Peet's coffee (Yeup, they are useless to me at home, but I got tired of carrying them around)

* Borders Reward card (ooops, looks like I haven't cleaned out my home stack in awhile)

* Amtrak rewards card (just need the number and website has this remembered)

* Local Library card (they can use my driver's license, but I can't use the self checkout, which is OK becasue the line isn't ever long and I don't use often enough)

* Library Card for the bigger city by me

* NSSA Press Credentials (only needed when attending certain sporting events - I grab this one as necessary)

* APIS Press Credentials (same as above)

* Bike Club Membership card (provides discounts at local stores, but they know me and I don't need it anymore)

* Panera card (I think I needed this at one time to access Wi-Fi or something)

* Card for my season ski tune & discount (though customized, I think they just look me up in the computer or remember my face)

* Season pass card to get into a apre-ski venue for free

* AMC Entertainment gift card (I go to the movies once/year, and everytime I forget to bring this thing)

* Safeway Card (only useful when I'm on the West Coast grocery shopping. I've since learned to use my Brother's phone number)

* EFTA racing license for mountain bike race series around here in the summer time.

* NEMBA Membership card (mountain bike related)

* Gift Card to another coffee shop

* Home Depot Gift card (exact credit card shape and size)

So, as you can see, I've optimized a good chunk out of my wallet , but it's not all the way there. Though a couple of my cards "could go" there's still about 12 or 13 essential cards I must carry with me.
You let the blocking call do a non-blocking call internally and then instruct an IO-aware user-mode scheduler to reschedule the user-mode thread when the non-blocking call has a result. This is what Haskell/GHC, Erlang and Ruby 1.8 do. There are some great papers on GHC's IO manager. In general, it is always possible to build a blocking interface on top of a non-blocking.
This quote:

“It has been estimated that the potential power from the
Florida Current, which flows from the Gulf of Mexico into
the Atlantic Ocean, is 20 gigawatts—equivalent to about 10
nuclear power plants,” mechanical engineer David Olinger.

The scale of human industry is currently around 16 terawatts, so something on the scale of 20 gigawatts is a drop in the bucket. The solution to all of our energy needs this is not. That said, sure, deploy as many underwater kites as you profitably can without adversely affecting the environment; every little bit of power we generate renewably helps.
It seems to me a backpack wouldn't decrease mobility by much, and would allow for more comforts such as a change of clothes.
Make native components matter
That Lemon Wallet app looks really nice. I'm going to give it a go... I've tired some others, but didn't like them.

Also, I was a user of both Belly and Level Up for awhile. But the merchants around here have been finicky with the services and some of the shops I frequent stopped using them.

Ooooh....this low-tech idea is very good. I've often wanted to create a single card (same shape and size of credit card) that I could print my essentials on so they could be scanned by a red laser scanner.
The design of particular bombs also plays a part - in most H-bomb designs the bulk of the energy produced comes from the fission of the tamper round the secondary by neutrons produced by the fusion reaction in the secondary.

If a non-fissioning tamper is used then a relatively clean explosion happens (e.g. the Tsar-bomb) - if depleted or enriched uranium is used as a tamper then weapons will be much messier. Indeed some weapon designs explicitly came in "clean" and "messy" versions (the latter often with greater yield) e.g. the US B53:

http://en.wikipedia.org/wiki/B53_nuclear_bomb

Also there is an option of deliberately including a material in a bomb design that will be activated by the neutron flux from the secondary (e.g. cobalt or gold)- so called "salted bombs":

A small backback would not be a physical hindrance, but rather a psychological one.
We've got a lot of the parts of this already built, just not packaged in this format.

We're trying to see how much support there would be for a product like this. If we get a lot of "signups" we'll get cracking immediately.

Comments/feedback more than welcome.

Thanks in advance for your support.

Games are way different segment. In a game you would like to impress person with non standard interface. In fact a game running on standard UI looks cheap and is a signal of design failure / low budget.

While the applications are other way around. New customers do not want to spend more than a minute to get familized with the interface. Moreover, your custom UI interface will be competing with Apple/Google designer's budget.
Curated articles for designers and developers
I have this fear either. I'll try your tips.
I supported the ThinFolio, I'm hoping to have another go with minimizing my wallet utilizing low-tech photocopying/pasting of bar codes to a single card & Lemon Wallet.

I think I'll be able to get down to about 8 essentials, and hope I don't forget the others when needed.

That's partly what makes this idea such a great bet. It's a positive sign Coin evokes such magnitude of excitement and disbelief.
It might make it a logical target for acquisition, but it doesn't follow that it's worth ~4% of Facebook's market cap when Facebook has 100x the users (including virtually all the Snapchat userbase...) and could trivially clone Snapchat's tech.

Not to mention that Facebook's own profit figures from their more diverse and mature advertising platform suggest it would take a very long time to accumulate $3bn in advertising revenues off 25m users.
Well, it gives them unlimited access to information, which helps a lot when arriving in a new city. The lack of a change of clothes is a bit gimmicky and relies presumably in being able to find a washer and drier pretty much anywhere.
I agree. So far this and others looks more like its disruptive solely within our echo chamber.

What will be disruptive though is if Udacity or one of the others can become a credible source for teaching. All of this means nothing on a larger scale unless it gives you skills and abilities others trust.
