How does Quantopian connect to IB?

Doesn't IB require a local TWS connection as well as credentials, e.g. 2-factor authentication?
In spite of the firmly stated opinion I left elsewhere in this thread, I do indulge in imagining how all this tech stack could be better.

First things first, I found out the other day that someone actually built the major part of my vision: Constraints Oriented stylesheets (using cassowary).

http://gridstylesheets.org/

This is how iOS now handles layout. It makes easy things easy, and hard things achievable. Exactly what you'd want.

Beyond this, I think that html has too many tags. To put another way, the browser should not generally permit <script> and <style> to exist in the same context that <em> can exist. onblah= attributes were a terrible mistake that we'll never be able to undo. It would be cool if there was something like a <content> tag which, within it, only permits content oriented mark up, while disabling scripting and styling tags. Likewise, forms, scripting, meta tags and linkages should be in isolated contexts.

And finally,
what idiot decided that & ampersands should have a prominent position in many URLS and then use & for entity encoding in html, a completely different purpose. URLS now have to be http://entity&amp;encoded

uhg. so stupid.
what would be wrong with <amp> or <amp/> instead?
or since we've freed up & for normal expected use, <gt> <lt> and <quot>

ah well.
God, I started out with Perl-based CGI, NetObjects Fusion, and ATG Dynamo's early JSP implementation, back when being able to afford a SQL backend meant you were hot stuff. Kids today have it so easy. We had to code ISAPI filters, during packet storms, for bidirectional communication! And don't get me started on what we had to do when the bit buckets ran out of ones....
XMPP has XEP-0273 http://xmpp.org/extensions/xep-0273.html

Nothing is over for XMPP until a better open alternative comes out. If Google see their Hangouts as a way forward, let them open the protocol and pull it through IETF to make it a standard. Oh, they are too selfish to do it? So they can get lost then, it's not an XMPP replacement.

No one else is eager to do anything like that as well, so XMPP remains the only candidate at present.

They don't need to afford it to be dumb enough to sign on a loan for one. Tesla gets the sales revenue, and later the customer goes to collections. Everyone wins.
They are being pretty cagey about who they are and where they were found. My guess, is that they went "partially" public in order to generate interest in selling these coins at auction, or via some other way to increase how much they can sell them for.

I'm staggered by how much they've ruined phone calls in Gmail, to the point that I can only assume it was deliberate (free US calls costing them too much money). It used to be like a GChat window in the bottom right of Gmail, and load up instantly.

Now it opens a fresh Hangouts window and takes at least 15 seconds to actually answer/place a call. Horrendous.

> But I still see the lack of reversibility of transactions (one of bitcoin's strengths) as the major problem here.

"Stop Saying Bitcoin Transactions Aren't Reversible" http://elidourado.com/blog/bitcoin-arbitration/

The n-of-m multisignature facilities described in that article are the future of Bitcoin. You probably don't need multisig arbitration when you buy a coffee or a stick of gum, but you probably do when you're transferring large sums. Of course, there was no multisig protection in sight in the MtGox case, but then there was no blockchain in sight either. Far worse errors of judgement were made there.

Bitcoin makes the use of arbitration services optional, and it makes the actual mechanics of arbitration services safer and more efficient. The arbiter in a 2-of-3 multisig transaction can't freeze or seize funds in transit -- hello PayPal! -- and takes zero action in the vast majority of cases, where there is no dispute.

Banks, credit card companies, and existing payment systems like PayPal can't easily, optionally disintermediate themselves. They must play arbiter. And we must pay for it.

> bitcoin tries to workaround them for no good reason.

There's a good reason. Why do businesses today pay transaction fees when you use your card to buy that coffee?

I'll just quote the opening paragraph of the original Bitcoin paper:

"Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party."

I've had a roundly "meh" experience with Google Now. Most of the information it shows me isn't relevant to me and anything that is relevant is information I already knew (I know how long it takes to get home from work, I do it every day). I like the idea, but I haven't been able to get much use out of it. How do you generally utilize it?
The argument can be made that you can't test in quality. On the other hand, based on speaking with some Apple developers that I know personally, it would seem that automated testing is not encouraged. Neither unit testing, nor a dedicated team of SDETs for many groups. Contrast that to someplace like Microsoft, where I've worked as an SDET and a skilled, dedicated test team for a product is just the way it is.

PayPal was a steal.
That's what makes it fun..
“Cold storage” does not “leak”. The idea that the funds were stolen,
unnoticed, from cold storage, due to Transaction Malleability,
strains the credulity of even the most gullible observers.

This part of the story still doesn't make sense.

One possible explanation that I haven't seen anywhere else is that MtGox lost control of the private keys to their cold storage.

How else could 744,000 BTC disappear, without anyone noticing, from cold storage?
To be fair, figuring out whether any quantum computing is happening without knowledge of what's going on inside the blackbox is like trying to prove that your VM is running on a server with X CPU, Y memory, etc, under the assumption that any APIs which purport to give you this information are untrustworthy. It's not a trivial problem in the analogous classical case either.
It was pretty limited, but yes.

To do what? International doesn't sanction killing people in defense of property; deadly attacks on pirates are only permisible in the name of self-defense. See http://jcpa.org/article/piracy-and-international-law/ especially section III.a.

Besides the ethics of whether to treat pirates as criminals or not, you can't automatically assume anyone moving on board is a pirate; they could also be in need of rescue. Ships are supposed to render aid to distressed travelers on the high seas, AFAIK.
I agree with that thought.

In fact at times I have purchased OEM hard drives through the Apple store instead of on Amazon.

My theory being that a manufacturer would (and this is important) be more likely to send their "A" production to Apple and do a better job of screening defects.

> HN appears to have true love for any story surrounding Tesla.

That might have more to do with the fact that the Tesla is largely software-driven than that it's relevant to HN's readers as Tesla owners.

Also, it's a model for a future environmentally friendly car. I say it that way because driving a Tesla using present-day coal-generated electricity isn't a huge improvement from an environmental perspective, but a future power grid that's more reliant on wind, solar and nuclear, greatly changes an electric car's environmental impact.
I am so, so, so sad that Yahoo! shut down Geocities, because they took with them the Pokemon fan website that I made when I was just learning this whole 'HTML' thing for the first time.

I even remember the exact full URL of the website[0]. But between the demise of Geocities and the demise of my 386's hard drive, that piece of nostalgia is gone forever.

I remember dedicating a page to all of the different "strategies" to catch Mew in Gen I games, before we all collectively decided that this was impossible to do without a Gameshark[1]. Little did we know that there was a technique - it just wouldn't be discovered until ~2003[2]]!

I don't have any work that fits into your criteria, or otherwise really, but I can offer this...Just get a job. Whatever the job is, you have people depending on you and clearly have the ability to work.

It might take you longer to launch, it might not. You might have to give up nights and weekends, or you might have to give up the project altogether...but, get a job.

This advice is coming from someone who worked on a startup for almost 2 years, with a wife and child and no other substantial or reliable income.
Well it does tell you that there are no IO computations with side effects. So you really are restricted to the Int type and the operations that can be performed on it.

You get much stronger statements by using type variables (not type synonyms). This is actually laid out rather clearly in Theorems for Free by Wadler[1]. The essence is that the more generic a type signature gets, the more you can reason about it's behavior. Since if you want to perform (+) (-) (*) (/) for example you'll need to include a (Num) constraint.

It is comments like this "The iPhone... is merely a girlie gadget with all the technological sophistication of a 1980s Barbie."

Which shows how hostile our industry can be to women.

They aren't buying an iPhone because it is any less capable or more feminine than a Samsung. Maybe there are other reasons.

Could it be the size of the iPhone is better suited to the smaller hands of women (not a put down, women on average have smaller hands than the average man).
Could there be other reasons?

I have a strong dislike for Apple products, but to say women purchasing them because they are 'girlie gadget' is offensive to women, and we as an industry have to speak out against this kind of BS.
I am sure in 50 years it would be 2064 and we would be a decade away from fusion. Just kidding about fusion, I hope...
Please move this discussion to the alt.www.webmaster newsgroup.
It actually can using generic type signatures with constraints. Once you use a concrete type like Int you are severely limiting the expressiveness of the types. Which is fine in some scenarios.
Interesting dataset, though I do have some quibbles. For example, registered users aren't the same as monthly unique visitors, which is how CNET is best measured. And ecommerce like Zappos have completely different metrics. One thing I would like to see is the user numbers normalized against web users at the time, which helps put late 90s acquisitions in better perspective.
"Forgive me, but I'm not really sure why this is getting so much attention."

Because because the level of professional incompetence it exhibits in a world where people think using iPods as part of an airline's essential safety process is a fucking whizzing of an idea. It makes the first order problem of using iPods to transmit confidential medical records feel rather trivial.

Yet there is nothing for which you need ask forgiveness. A model of the world where everyone lives in circumstances where either Comcast or Verizon is always available for one's internet connection [and it goes without saying that neither could possibly be compromised] is so absurd that you can only be speaking tongue in cheek

It's more that D-Wave has gone off and abandoned the approach that everyone else is taking with their machine, so it's not clear if you can call it a quantum computer.

Imagine if I had a box that didn't have a cpu, or anything like a cpu, but could still solve a particular type of computing problem. It's kinda weird to call it a computer when it lacks the part that computes, but it still gets results for a subset of the problems.

On top of that, the D-Wave has far larger numbers, like it's 509 q-bits for this one, but it can't solve problems of the size we could if we had a 509 q-bit regular quantum computer. It's not really measuring the same thing.

Oh, geez, I did not really finish my point:

In the U.S., welfare -- which requires a woman to be both a mother and unmarried to qualify -- actively discourages "shotgun weddings" and changed the social contract so that having babies out of wedlock is now much more acceptable than it was when the system was conceived. At the time, it was inconceivable that women would choose to intentionally have babies out of wedlock. This is no longer true in the U.S.

So, that is how welfare in the U.S. grew the population of "poor, single moms" -- by actively encouraging out-of-wedlock births. Single moms are typically poor. Families with two parents are usually better off.

I've got nearly 20,000 miles on mine. One thing I just discovered is that the tires, 21" super-soft compound high-performance Michelins, only last 20,000 miles and cost $2900 to replace.

Even with non-renewable energy sources, creating the power at a massive GE Turbine is more efficient than a gasoline engine. Internal combustion engines are ~30% efficient in converting fuel to energy releasing the rest of the energy as heat. GE Turbines used at 100+megawatt powerplants are 60% efficient. Same fuel source, twice as efficient. So even if we're not using wind and solar, electric is better for the environment.
