There are, but they aren't close in specs and price to this one. The AT91 series are completely different in terms of functionality vs the Broadcom. The AT91SAM9 series don't even have a floating point unit last time I checked. This chip can do full 1080p h264 encoding/decoding/and support that resolution for display output (HDMI and DSI). This also has flash storage and 2x more ram onboard.

This might be a close equivalent, but is more expensive, and will almost certainly require a large order to get those prices: http://www.variscite.com/products/system-on-module-som/corte...

If this brings down prices of the commercial SoM vendors that benefits all of us however.

I was surprised at how unobtrusive my Note 2 is in my pocket. When I got it, I made sure I knew the return policy and had a backup phone picked out in case it was a pain. Honestly, it is less noticeable than my Motorola Droid 3 was. That phone was think and felt heavier. I generally keep my phone in my left front pocket. When driving, I almost never didn't know my phone was in my pocket. With the Note, I sometimes have to glance down or pat the pocket real quick to make sure I picked up my phone.

To be clear I think Apple has a great model, but they need to be realistic that it won't last. The only markets in the world that the iPhone has substantial market share is in countries with subsidies (at least I believe so). In markets with no subsidy, Android is killing.

As the US (and the world) moves more to a non-subsidy model I think this disproportionately impacts the iPhone. All OEMs will have to deal with this, but Samsung, LG, Huawei, Coolpad, are used to this world already as they sell really well worldwide. iPhone hasn't figured out how to sell full price phones around the world.
That's also true. And another reason to stay away from sci-fi inspired prognostication, like a lot of comments here where space ships five orders of magnitude heavier than anything yet built are blithely assumed to be possible. Most of it requires magical solutions to very hard problems. David Brin is one of the few writers i have seen take on the "it's really hard, and insanely expensive, to get anywhere" problem and make a story based on that problem. The most plausible future doesn't have animals that look like us running around in it, never mind traveling to other stars. And that makes it hard to sympathize with, or even imagine, the protagonists of stories about the far future.
Tech stock sell-off spreads through world markets
Mostly because a tablet is very well suited to the whiteboard, and we find that the whiteboard _really_ helps for this kind of working collaboration.

It makes it really easy to gesture and discuss visually.

As far as iPad vs Android - that's just because we have to start somewhere. Also, I worked at Apple for 7 years, so it's definitely the environment I'm quickest at programming.

That said, if people actually like what we're doing, who knows. The main point is the conversation, the tech just enables it.

(Oh - and yeah, you definitely do the SICP exercises on the computer. That's by yourself, though. When we chat once a week, we do often write out snippets of code or problems, but the use of the interpreter already happened.)

Take a look at the Moto X vs. an iPhone 5S:

http://www.phonearena.com/phones/size#/phones/size/Apple-iPh...

I don't think that's really a huge footprint difference (1/4" in each direction), but the iPhone 5S has a 4" screen and the Moto X has a 4.7" one.
In my non-scientific observations, some women seem to really like giant phones. They typically keep the phone in a purse, so the bigger it is, the easier it is to access. They also tend to use the phone in a two handed operation.
My first thought on reading this is that it's counter to what's recommended with Deliberate Practice. This system seems to start with failure and then backs off on the difficulty until the learner succeeds. Deliberate Practice starts within the learner's capability, and pushes outward, trying to stay right at the edge of the learner's capability. I don't see how starting out with failure is going to be very encouraging to the learner.
Getting By on a Writer’s Income
At the expense of the buyers--those who are actually attempting to "invest" in the land (rather than speculate). If Disney decides they are going to build a theme park in some area, they should be entitled to buy the land at current market prices, not at an inflated price (solely based on information of their intention) that essentially robs Disney of profits from their own efforts. It is Disney's actions, and their expected future profits, that create value in the land. Frontrunning their purchase is unethical any way you look at it. The market will adjust as it sees fit after Disney's purchase succeeds.

The land analogy is a bit strained, as those who buy stocks are necessarily betting on future earnings rather than investing their own labor into its growth. But I think the analogy holds for those who put in effort to analyse an industry and thus make buy/sell decisions based on their efforts. Frontrunning or behavior analyzing is essentially robbing a company of the fruits of their efforts. The market will adjust based on their buy/sell transaction, it does not need another middle man to adjust market price a millisecond sooner.
The fact that this battery is bio-organic is a good sign, as typically the reason batteries haven't advanced at the exponential rate of other technologies is that they are based on chemical reactions.

The way Zidisha markets its rates feels like a lot of services I see. It's how my phone bill, electric bill, almost all my bills work - hidden fees charged by everyone so you just assume you're going to be paying more than is quoted.

They're following the status quo, are probably not intending to be evil, and are surely feeling the pressure to be 10x better.

But I worked in the Philippines in college, and you want to know what would really blow their minds? Not screwing them over. Everybody else does that. 10x better is being honest. Given their alternatives, 25% isn't that bad. Initial adoption might be slow - they're so used to corruption and being bullshitted that they'll think it must be 25% plus something - but once word spreads that Zidisha is really just 25% and offers the most valuable commodity in places like this - honesty and transparency - it will blow up. And then you'll get more fraud, but that's challenge 2.0.

Ethereum founder here.

The general four categories of options that we had are:

(i) a traditional banking/tax haven (Isle of Man, Panama, etc)

(ii) Switzerland

(iii) Iceland

(iv) Singapore / some other "Asian tiger"

The reason we discarded (i), aside from reputational concerns, is that such jurisdictions tend to be unstable; they are nice to you right up until the US government wants them to stop being nice to you, at which point they flop over in ten seconds. (iii), while nice for other crypto-startups, is bad here because there is unfortunately a hostile legal environment for cryptocurrency. The choice between (ii) and (iv) is arbitrary; both categories of jurisdictions have a good legal environment for these kinds of projects, and both have a reputation for being reliable and consistent. We chose Switzerland because (1) the government is more accessible, so there is no need to wait six months to talk to regulators, (2) we are working with OpenTransactions, who had an established understanding of the local legal environment and have been able to provide massive help to us, and (3) because it's linguistically and culturally easier for us to deal with Swiss regulators than Chinese regulators.

So it's not at all a free-for-all; it's a solid legal environment with an established reputation for stability that meets our objectives. If we wanted/needed a true free-for-all, we would be working with Panama.
You completely missed his point about the difference between non-public information and new analysis on public information. Anyone can go and count the number of cars in a WalMart parking lot. This is new analysis on public information, not non-public information.
lessdate, the new online calendar in public beta
Out of frustration and limited user experience using Google Calendar and dependency with other third party plugins, lessdate aims to provide a better calendar and up-to-date with the current trend and use. Hence, a modern, cool and dead simple calendar on all devices for everyone is created.

Some of its unique features are intelligent icons rendered based on input text, a set of wallpapers to choose from and other basic and user centric features. Not too complex and overloaded stuff.

Give it a try and feedbacks are much appreciated.
Thank you!

Yeah, and isn't it true that the traders managing those large orders never enter them through traditional means anyhow? They either submit them to "dark pools" where the huge blocks can trade with other large participants without impacting the market as much, or they enter them as algo orders with their broker and they are split up into many smaller orders throughout the day with the goal of transacting at the average daily price.

Everyone's pockets are different. I know Galaxy Note (5.5" screen) owners who comfortably keep their phone in their front pocket. I know iPhone (4,4S) owners who can't fit their phone in anything but their back pocket or purse. I personally find any phone uncomfortable in a jean pocket, regardless of size.
Not in a competitive market, and on-exchange liquidity provision is the most purely competitive market out there. My quote is no better than anyone else's, so anyone can undercut my price.

Imagine the grocery store example I gave. Say meat costs $5/lb wholesale and your transportation costs to drive to the meat market in a car are $1.50. A grocery store using a truck to pick up the meat and freeze it in their store can transport the meat for $0.50. In a non-competitive market, they would charge you $6.49 for the meat, and you'd prefer to buy it there since it's less than your alternative of paying $6.50. However, if there are two grocery stores across from one another, they can compete on price to win your business, and the price of meat will end up being marginally above the costs of whoever can transport/store meat the cheapest, maybe $5.55 or something. The end consumer captures most of the surplus value.

The same thing happens in trading. Professional traders are more skilled at managing positions and trading across markets. By electing to trade with a market-maker's quote, you are effectively giving them your trading problem. Unlike the grocery store example where only a handful of businesses may compete, there are dozens of firms engaged in automated trading all competing for your business by offering tighter prices. They'll continue to do this as long as it's profitable, but competition will erode their profit margins until they're slightly above costs.

HFTs made a killing when they had first-mover advantage, just like if you were the first company to use smart logistics software or any other innovation. Now, not so much.
Does anyone know of a good explanation of how plyr, dplyr, data.table and *apply functions differ? I'd love to read an in-depth analysis of each and make an informed decision on which one to use going forward.

My current m.o. is to use data.frames as needed and plyr if I need to do any serious manipulation (which means that every time I use plyr, I need to read the docs). There's a lot of benefit to picking one direction and sticking with it...
thanks for cutting through all the bullshit and showing the real technical facts. I'm tired of listening to HFT defendants pointing out the necessity of their service in their own overly generalized and useless models.
Unreadable fonts are preferred for dyslexic readers, because the uncomfortableness of the font inhibits scanning (error-prone for dyslexics) and promotes reading-letter-by-letter. So there is a tension.
Copying from a post I made on Reddit:

Lately I have become much more comfortable with the idea of computer-controlled systems for one simple reason: our world is already computer controlled. The computer in question is the universe with its laws of physics and humans provide the inputs to this great multisig by manipulating their body parts. At the "base layer", no semblance of compassion really exists: the person who wins is the one who can wield the most violence. This is true even in anarchies; when it comes down to it, it's the guy with the guns who has the final say. And yet humans have managed to take this base layer and build all sorts of other structures on top. The world of programmatic smart contracts is exactly the same; it's just a set of cryptographic "laws of physics" that you can build stuff on, except it's designed to be both much more efficient and at the same time voluntarist at the core - unlike in the "real world", it's much harder to successfully steal a private key than it is to create and use one.

"we require that so we can automatically intercept login approvals SMS messages for people that have turned 2-factor authentication for their accounts"

Wait, how does that work?

Doesn't that kind of break 2 form authentication?

If no input is required by the user then it's pointless. If I hack your account and Facebook sends your phone an SMS to authenticate but the Facebook App automatically "intercepts" and reads the SMS message and says "Yup! It's good!" What's the point in sending the SMS message? Think about that for a moment. Why not just send a request to my smart toaster and have my smart toaster just reply "Yup, I got your message!"

Am I missing something?

Which the HFT firms have earlier access to and greater ability to respond to. Can this legitimately be called fair?
While is commentary makes an excellent case for dishonesty on Zidisha's part, I wonder if some context is necessary. Looking beyond the dishonesty, this commentary talks about a 25 percent interest rate in the implicit context of the credit environment of a developed country. In that context, these practices and interest rates are extremely suspicious, morally dubious, and possibly illegal.

This raises the question of why Zidisha is making these statements. To assume a developed-world business context excludes the possibility that these practices are accepted and commonplace in the markets Zidisha serves. I have no experience with those markets, but it's worth excluding this possibility before expressing distaste for these practices.

Consider the following plausible scenario: Zidisha performs research into the market and discovers that these practices and rates are acceptable. One can even imagine they are preferable to the status quo. The issue is that Zidisha as a company has to generate press and justify its business to a developed-world audience whose gut reaction to such practices would make the company look like a pack of usurers, when in fact they could very well be doing a lot of good.

To me, this communication seems a compromise response to this conflict: translate the numbers and practices as best you can into language and terms developed-world audiences understand. Perhaps the company took some liberties with labeling and conversions along the way, and if this is the case they would do well to be more conservative, but overall I give the benefit of the doubt that this communicate is the result of a tricky conflict of business environments rather than deception.
Since Jobs died, Apple hasn't really created a new product category that none of us knew we wanted.

Jobs died a relatively short time ago; even when he was at Apple, it's not like they created new product categories all that often - maybe every 3–5 years?

I can't help but feel people have expectations which are a little too high.

Apple has to live in the real world. It's actually reassuring to me that they are able to consider these kinds of facts. It's certainly the job of Schiller and the marketing team to understand what the market is doing.

I agree with you that they need to design something great to serve the demand and not just follow others.

However, as an iPhone user, who loves the portability and one-handedness of the small form factor, I am using my phone for 'real work' all the time now, and would really like a larger screen for things like quip and mindnode. I think the demand for different tradeoffs is real.
What leads to that design? I mean, why are they going to such expense to keep wire separated? Was insulation prohibitive? Had twisted pairs not been invented yet, making crosstalk too severe on closely bundled wires?
This may have already been posted in another thread, but it doesn't appear to have been posted here. But this is a great visualization for the Pythagorean Theorem.

An analogy to futbol:

Good referees make the calls that need to be made at this time, in this game, with these players. They have discretion. Compare that to basketball where all fouls must be called even when calling the foul clearly rewards the team committing the foul and gaining that reward was the explicit reason for fouling.

The reason futbol can be officiated differently from basketball is because futbol has Laws and basketball has rules. The futbol referee doesn't judge events solely by the book, but also by their effect on the Spirit of the Game.

The duplicate post heuristic exists to prevent problems and maintain the general enjoyment of HN. It's not there to encourage lawyering up and arguing a case, because that's nothing but a headache.

If this is seriously likely to affect you, act on the side of caution. Act as if the rules were explicit and restrictive and the punishments severe. In other words don't try to get away with something, and if you do, don't complain if something unpleasant results.

As Thomas Hobbes theorized, the sovereign's sole responsibility is to do whatever is necessary to keep the peace and we cede some of our autonomy for the sake of that peace. It ain't a democracy.

Yes. :-) When people tutor kids, they make sure there's always another adult in the room. That's hard for us, so no kids.
Yeah. I've come to realize that the hard way.

It is also what it comes down to w.r.t. code-over-config.

To make a system sufficiently configurable, you end up having to re-invent a turing complete language inside it's configuration files, so it starts looking more like lisp.

This is due to the [1] Inner Platform effect.

The only interfaces I know of that's expressive enough to drive a turing complete language is either flowcharts, or actual code.

This is kind of why I feel that systems like gulp are just superior to grunt, because ultimately the config format can never be expressive enough to solve all the problems, and there's just so much less work to write-what-you-mean, the first time. properly.

This also relates my newly adopted philosophy w.r.t. software complexity. [2] Simple vs Easy.

I learned this the hard way when using gpg+mutt back in 2001. All my Sent mail was being encrypted only with the recipient's key, so I couldn't read it myself. There's an option to also encrypt outgoing email with your own GPG key.
I'm not sure what they are using to serve up their site, other than nginx. But they do have this header, "X-Hi-Human: The AIRBNB SRE team added this header. Come work with us! Email dave+header@airbnb.com"
I love my Note 2. It is close to perfect in the size category. As part of my job I sometime test on a 4" iPod Touch, and it feels to very tiny. I can't remember how I even used my old iPhone 3G. Typing on the 4" was painful; the hit target was so small.

I think this is one of the reasons that Samsung has taken such a large share of the market. They offer devices in a variety of sizes, for which they've been criticized, but allows for a perfect size for everyone. I know I could never go back to a smaller screen size.
