Despite their claims it is not really open source, but you can buy the official dev kit for $100 and it gives you access to the SDK, Soft devices and an SWD programmer (SWD is like JTAG but for ARM).

Great hardware though. The only alternative I've seen is the TI chips and they require the purchase of a $3k compiler!

Persona was only recently de-funded, while Brendan was already in charge of Engineering.

I don't think it was because of a lack of belief in Persona and the value of pursuing federated identity. I would guess that it came down to priorities.

I think it depends a lot on your target audience.

- If your users are "in control" of their own business -- if they handle refunds and customer service issues themselves, if they'd like to log in to their own dashboard, etc. -- I think Connect[1] makes more sense. This is what, say, Squarespace uses.

- If your sellers are providing a service to another company, and expect that the company will take care of everything (a la Lyft and Postmates), I think the transfers API is a better fit.

Does that make any sense?

very interesting point. I agree that maybe an updated CF TOS could help quell this issue, but then again I don't think CF is going to dedicate too much time to vet out any potentially bad sites.
This is actually the pain point we were trying to solve with mod. Each time we'd fill up a notebook we'd manually take pictures of every page and save it to evernote. If you've ever done this you'll know...

- It takes FOREVER.

- Pictures are blurry / out of focus / misaligned

- There's a limit to the number of pictures you can attached to a note in evernote so each notebook ends up needing to be spread between a few different evernote "notes".

- Evernote really isn't designed to consume this kind of content. (We have an app designed specifically for this: http://app.modnotebooks.com/demo)
Stereotypically those were FDM so you'd send precisely two cycles of 1200 Hz or one cycle of 600 Hz and then a simple zero crossing detector would sync up and read the bits out.

I figured thats where he was going and was kind of surprised to see the multi-tone setup.

The more advanced ham radio guys are experts at using vaguely communications width bandwidths at often very lot signal to noise ratios to send as much error corrected data as possible.

20 years ago you'd demo something like PSK-31 using two COTS laptops just singing out the speakers and it would work pretty well. Newer modulation schemes are obviously faster / lower SNR / better error recovery / better PAR (peak average ratio) etc. A smart telecom engineer can run right up against the Shannon limit and flexibly trade off against limitations, either SNR or audio bandwidth or transfer speed or synch / preramble time...

It has a reasonably decent (highly decent for a header file) description.

One thing I had to take a guess at is that, in JEntry, the header is a combination of a bit mask and an offset. I also would guess that offsets for identical keys (can happen in nested json), and maybe offsets for other identical data will be identical. I didn't check either.

You cannot conflate bigotry with homophobia.

People may simple be bigoted towards gay marriage, but hold no strong opinion on the individuals themselves. That this is a possible stance is self-evident given the current legal situation.
To be fair: "they'll adopt kids and turn them gay" doesn't really have a parallel in the interracial marriage debate, as far as I can tell.

The top rated answer is extremely complicated.

Real life examples that are considerably easier to understand exist.

However, the easiest way to show a user the problem is to demonstrate the use of the "insert" key on any keyboard. Instead of adding characters, it'll write over existing characters.

I think most users should know about the dreaded insert key from accidentally pressing it. If not, you might need to sit them in front of a computer.
> Think of having sex with 12 years old girls - there is nothing irrational in it (it was normal and legal a few hundred years ago), why we keep it forbidden now?

Since the beginning of the Industrial Age, we've lengthened human childhood. Because people have more to learn today before they can be productive adults in society, the period of your life that is "youth" is longer, and the age where we consider a person mature enough to be fully responsible for their own body is older now.

12 year olds used to be adults, now they're children.

> Similarly it is not legal to merry 4 woman (or man). Why? Where is rationality in forbidding this. In fact rational is the opposite - it would be good to have spare wife or husband, just in case of death or ilness.

If there was complete gender equality and polygamy was as common as polyandry, it would be probably be fine. In reality, polygamy is historically dramatically more common than wives with multiple husbands.

If you take as a given a roughly 50/50 distribution between men and women (and relatively even proportions of homosexuals), that means widespread polygamy causes a large number of men for whom there are no wives available. If one person has five wives, it means there are four men out there with none.

That has a destabilizing effect on society. It's best for everyone if the possibility of finding a mate is not hampered in that way.
I don't see any new features being launched here, but it's a nice landing page that sets out the value proposition and use cases for marketplaces more clearly. Yet again making me wish that the Transfers API was available in Europe!

It's a pretty common model -- create some valuable way for buyers and sellers of some service to connect.

You're being obtuse. Are you trying to say that minorities oppressing a different minority is somehow relevant? It isn't. That is completely within the normal (and bad) operating parameters of human nature.

HN's stupid anti-flame wankery won't let me respond to you, but the point of this parable in this context is that a person caught a break, then immediately turned around and oppressed someone less fortunate. Based on the way you seem to be parsing things, I honestly don't expect you to get this.

Basically, all this does it make it so each "seller" doesn't have to create a whole Stripe setup. It introduces a middleman who collects a fee. Useful for some applications, I guess so.

I can see this mostly used on smaller-scale projects or businesses. Otherwise it just makes too much sense to set up your own Stripe, especially considering how easy it is to set up Checkout.

For what it's worth, they have a graph of a test of a 2 (!) cells at [1]. From a sample of two, it is quite extraordinary, indeed. I find it very hard to believe in the Altair->Microsoft hypothesis. Altair to microsoft was a new practice overlooked by the big guys. Lithium charging is a very concentrated area of research with lots of investment.

For comparison, I found [2] which is a test done of pulse-charging by Electrochem/ENREV and a university. This area of research has been going on for almost two decades.

We already have great, modern and maintained screen alternative: it's called tmux. And yes, it's written in c, but don't immediatelly see any reason why it would be much better to rewrite it in Haskell. And I'm saying that as a XMonad user who knows a little bit of Haskell.

But you know, there is nothing stopping you from trying it yourself to show that this idea is actually viable :)

Edit:

There are actually few reasons why the XMonad model would not be a good fit for screen like program: XMonad requires haskell compiler to be installed on machine you are using it - this is fine for my personal machine running recent fedora (or any recent linux distro), but it would be a problem for all those servers I have tmux installed - like RHEL, Debian stable or FreeBSD, tmux is often already there or easy available in official/semioficial package because (among other things) all it's dependencies (few c libraries) are likely already installed. On the other hand you do not want to install ghc on much servers for obvious erasons :)

But as I said, if you like the idea, just go and make it happen - it sounds like a fun project to start. But I'm afraid it would not be much practical.
Awesome to see more ways of solving this problem. I usually wouldn't reach out to recommend that one to clients because the maintenance costs of doing parallel development on three products steadily diverging from each other get quite considerable indeed, but if it works for your circumstances than awesome for you.

If hypothetically you wanted to try this with A/Bingo without making in-line calls everywhere, it's possible, but not documented anywhere. I treat the knowledge like a spell to summon the Elder Gods: too terrible a magick gained at too high a price to destroy outright, but it will certainly be buried under a forgotten temple and guarded by fanatical cultists (and maybe a dragon) to keep it from destroying the minds of the unwary.

Just kidding: it's actually just "Monkeypatch the Rails internals to change the bit which finds templates from looking in /app/views/$RAILS_CALCULATES_THIS_PART to /app/ab_tests/$YOU_CALCULATE_THIS_PART/$RAILS_CALCULATES_THIS_PART." (Though sometimes when looking at that code I wish for Cthulu's sweet embrace.)

I hear you though if you also want to do extensive logical reworking in addition to reskinning substantially all the pages of the site. The one time I did this using A/Bingo, in lieu of doing a total app rearchitecture, I made a utility method to encapsulate the A/Bingo call and then hit the 10ish points in the code base which were going to be shared but not totally equivalent between the A and B variants. A bit of a pain in the keister for a Saturday morning but the test raised sales by 60% so I'll put it in the win column.

This is for products like TaskRabbit, Lyft, Postmates, HomeJoy, OrderAhead, and so on -- products that happen to involve some amount of each charge going to a third party. They generally aggregate the demand and build the UI themselves, though -- without them, there is no product.

Your stance in (3) is debatable. These are both issues that have more affect on poor people. E.g. In the Northern hemisphere, the east ends of cities are generally where more poor people live because they are downwind of the pollution (if the geography allows for an east end).

> It is totally fine if some people don't work as long as enough work that we can produce enough to meet demand.

That's precisely the point: it creates a market for labor that does not currently exist. If there were not enough workers to meet demand, the suppliers would have to increase salaries until enough of them decided the money was worth going to work.

A UBI allows natural market forces to do things that we have to do with regulation now. Minimum wage could be eradicated with a UBI, for example, since everybody enough to live on. Real wages for unskilled workers would be forced much higher, which I think would be a very good thing for the economy as a whole.

I mean, this conversation has been around for easily 10 years. We live in a world where we already have to do this—look at all the progress in the last decade on the prevalence of futures, async i/o, and channels/queues/whatever. Memory bandwidth and latency has proven to be far more of a performance drag that has improved far slower—the likely areas that will lead to performance problems will be in areas other than single-core clock speed.
Just because I'm succinct doesn't mean my assertions of fact are less valid than the rest of them. I'll gladly go into more detail when I feel like I'll be given a fair hearing.
We've actually had these APIs for a while (https://stripe.com/blog/send-payouts-with-stripe). But now we have a page that describes what you can do with them.
If 4.4% IE6 usage rate in China is accurate, that doesn't seem worth the effort.
Perl is not necessarily faster than C at all string manipulation, but it does have some handy features that makes short work of more complicated functionality. See here: http://www.perl.com/pub/2001/06/27/ctoperl.html

Sometimes Perl does things more uniformly across different systems than would be done on a single system with a different language like C. For example, this is Perl's malloc implementation: http://perl5.git.perl.org/perl.git/blob/7742aa6637b99424497e...

Depending on what you are doing, Perl may have a more efficient way of tackling the problem. This isn't to say you couldn't do it in that exact same way in a different language and find a faster result; it's just that Perl already does things efficiently, so you don't have to spend time tuning algorithms.
To be completely honest: I don't believe anyone has that position in good faith.

(Sandstorm author here.)

It is like Docker, except more user-oriented, with a complete web-based UI for installing apps and such. It also has a more complete story for how apps talk to each other. With Docker, as I understand it, you'd arrange for the containers to open ports to each other, which is pretty clunky. Sandstorm will let one app say "I publish an API implementing Cap'n Proto interface Foo" while another app says "I want to use an API implementing interface Foo", and then the platform presents a UI to the user to select which app to connect to, and handles all the security behind the scenes. Also, the unit of containerization is each individual "file" -- e.g. an Etherpad document -- so that the platform can handle sharing and a security bug in the app doesn't allow people with access to one document to hack their way into others.

I take a different perspective on the marketplace problem. There are lots of awesome open source web apps and other hobby projects out there that are currently hard for end users to use, because most of them require running your own server. The platform is aimed at bringing that whole existing ecosystem of apps to a wider audience. Yes, big companies like Google aren't going to develop for this any time soon, but that's beside the point. I want this to be the Ubuntu of the web. :)

As an example, the "Hacker CMS" app at http://sandstorm.io/apps/ was developed in a day from existing open source components. If we could harness the creativity of lots of developers tinkering, some really useful stuff to come out of this, regardless of whether businesses decide to target the platform (though I think they will too, eventually).

While I was there no one got rich off of it but a few people got some nice bonuses. I don't understand why more people don't do this.

Yeah, a lot of this page is about clearing up confusion -- turns out many people didn't know that we had these APIs.
Hate to be skeptical but I agree, the comments here are way too short and positive compared to what HN normally has to say about X or Y startup.
"The real problem is that any modern x86 processor including the Pentium III can execute multiple instructions at once. So it's not like emulating a Z80 doing one instruction at a time. The actual algorithm and how x86 does this is undocumented and still unknown. In short, the Xbox's CPU can be emulated, but not accurately."

How is that relevant? Is there any code compiled for the Xbox that actually relies on how the P3 handles microops and pipelines things and all that? Cause if your argument is "X=A+B+C+D" might have several different ways of happening, the answer is that it doesn't matter. So I'm not sure why the author bring this up.
