Bitcoin isn't really in the adoption by vendors stage yet. Two things are happening right now that are driving the price:

1) Adoption in politically sensitive markets (drug dealers, disaporas, people in corrupt states, etc) who have no other options.

2) The slow process of the finance world understanding what Bitcoin is, and how to value it.

The first is happening because there is demand for it. The second is happening because global finance organizations seek out and exploit any and all market opportunities.

I think what we'll see in the next few years is that #1 will keep growing, and #2 will cause wild swings in bitcoin prices as we develop the technologies and scholarship necessary to truly reckon Bitcoin's value.

At that point, the markets will have a good bead on the true adoption rate and the market mechanics, which will allow them to converge on a more stable value. Only then will Bitcoin start to become a good medium for broader consumer exchange.

That said, even if it's only ever used for politically sensitive transactions, and it never takes off as a consumer payment service, it will be a very big economy.
What if you include the value of not having to pay for airport parking? (in cases where e.g. you couldn't find a ride to the airport)
Compared to what physicISTs, biologISTs, or these scientISTs practice, computer scientists are more likely to be mathmatICIANs and logiICIANs, right? So "Computericians" might be a better title for them.

Also we have the word "Hacker", which is a marvelous invention, and which make these scientists that deal with computers sound so different. Though sometime it's hard to draw the line between what we call "computer scientists" and "programmers" when we use "hacker", but "hacker" is initially been employed as a term for academes, and what's more, we like it, right?
The real question to ask's oneself is why even bother attempting to 'capture' users. The real users you should be pursuing are the ones that are seeking the solution your site/product/$gadget offers and those are the ones willing to put in the time to resolve it. I want a loyal clientbase, not those ready to abandon their attention & my service at the next corner.

I'm not entirely against capturing as many users as feasible, but having 'been around the block', I'm of the understanding that they're the sort that'll inevitably abandon your service either way leaving you with a vapid userbase that's a distraction from your core users/clients. Quality > quantity applies. I too admit that if I can net 100x the amount of users inevitably a larger % might stick around, vs. netting 1/10th the userbase and still losing roughly the same amount to attrition.

Note: I didn't actually read the article as the site didn't capture my attention.
> Intrinsic value is derived from what you can do with something

So then, the market price of any good is its intrinsic value? Under this definition, if I can sell a bitcoin for x USD, then its intrinsic value is x USD.
Courtesy without consequence, clout or wherewithal is a dud.

Let me unpack that a bit:

People walk all over courteous people especially when they wield no social clout or when the person is of little consequence, in general.

Courtesy is too often taken -- in North American circles these days -- to be a dose of deference paid in advance for a future (and usually much larger) reciprocal dose of consideration or favor of some kind.

In short, unless you wield considerable worth ( of some kind ) no one's going to rule in your favor -- and against a much more formidable party -- owing to your courteousness.

It's unfortunate.
Well the most disturbing thing about this syntax is for sure the use of parentheses. Drop them and you will get old good ng-click="doSomething" which doesn't differ at all from class="ng-doSomething" or data-ng-click="doSomething".

But parentheses try to lookalike the onevent attributes, which a) everybody doesn't like and b) immediately invoke javascript code

In AngularJS point b) can't be the truth - there is for sure some layer of expression evaluation, and that is what disturbing - as an experienced javascript developer you know that this layer exists, but you can't easily see what happens inside that layer - AngularJS hides that from you.

In most cases in traditional JS development - nothing really happens in this layer, it's just a dumb method invocation in the context of the view and has dom event as a single argument - this is clearly visible in libs such as Backbone.

But in Angular this layer of expression parsing and evaluation does exist - and you don't know what kind of magic happens there and how thick, maintainable and overridable this layer is. This possibility of dirty magic - that really disturbs me in all the simple tutorials of AngularJS, so I don't have courage yet to give it a try in a serious project.
>in fact, you are probably going to do much worse due to the weight of the "fusion hardware".

Ion engines have weight, too. What leads you to believe that the fusion hardware will be heavier?
> Be careful when you use words like 'intrinsic.' It may be argued that fiat-currencies are 'intrinsically' without value either.

No, that's not arguable, its part of the whole point of fiat currencies is avoiding intrinsic value and replacing it with fiat.

Commodity currencies rely on the intrinsic value of the commodity to provide certainty that the currency will be exchangeable for goods and services (providing a lower limit on exchange value.) They also rely on the inherent supply characteristics of the underlying commodity to control the supply of the currency.

Fiat currencies rely on the issuing government (or participating governments, in the case of something like the Euro) accepting it for taxes, fines, and government services for the same purpose, as paying some or all of these is common enough that it provides demand for the currency, and rely on active management by a central bank to control supply of the currency.

Bitcoin's mechanism for control of the supply of the currency are algorithmic, and much has been said about them, but the value basis is ... less clear.
You're wrong about the consensus thing, from the perspective of people who use words like 'patriarchy' in a off-hand no-explanation-required fashion.

An appeal to consensus - never mind being logical, consistent or mindful of context - would be an improvement over where these debates with patriarcy-theory indoctrinated feminists always end up, which is 'you're wrong by definition'. That is, sexism can only hurt women because that's what the word has been defined to mean. It's utterly ludicrous and intellectually bankrupt approach to dialogue of course.

Egad! Yet another edge case to remember.
I was quite astonished when reading about their insane growth. Most of the companies we talk to in The Netherlands (Telco's, E-commerce, Banking / insurance, travel) are using VWO, Sitespect and last week I heard two clients talk about Maxymiser. Not one time I heard them talk about Optimizely. Seems there is still a lot of room for growth (at least in NL).

We (usabilla.com) are using Optimizely with great satisfaction though!
We can call ourselves "algorithmists."

I think you are largely correct (and no, you are without doubt not the only person to think that ;). However I do think that to some degree the ability to buy drugs with it plays a role in its value; it is not just a financial toy.

"9 years and counting"???

This title has an ominous tone to it, given their tendency to shut down services (Reader, Code, iGoogle, Video, Wave, et al)...
Yes, but that's because those governments have allowed their currencies to be free float currencies or something like that. Buying and selling an Indian Rupee for example is quite heavily restricted. Probably to prevent instability caused from speculation.

BTC never had that from the start because it's pretty much unregulated from the get go.
Ask HN: Good online course on operating systems?
I have some glaring gaps in my CS knowledge that I have been having fun filling. Next up is one of the biggies, either operating systems or compilers.

There is a Coursera compilers course which looks decent but nothing for operating systems on Coursera, Udacity etc. There are courses from Stanford, Columbia and Berkeley with some resources online, but none seem to have video...

So how about it, can you recommend a course, or failing that a textbook?

Thanks!
Do you have any recommendations for how to stay organized enough that you can keep track of these things?
Thanks for the reply.

I meant the question to be more from a technological standpoint. Anxious to see what you come up with. That's a wobbly road when you start trying to differentiate.

"Most of our employees don't have access...", uh, "Many of our employees can not access...", hmm, "In the case of sudden...", no, "Should there be an issue...", uh...
It's a bummer, not sure why this happened. I liked Gary, and saw him as the right man to shepherd Firefox OS from conception to production.

Searching for a new CEO is a huge distraction, particularly at this crucial time when they're trying to prove a major pivot and work out commercial deals with device makers.

So far at least, all of Google's for-pay services are relatively niche/targeted at power users. I use Google products EXTREMELY heavily and I've never had occasion to consider a paid service of theirs. I think the overlap between "fix the interwebz" people and potential customers for paid services would be approximately zero.

It is possible however that what you're saying will open the door to charging for less niche services, but that's a whole 'nother can of worms.

In the postal system, your message is generally encapsulated in a tamper-evident envelope, carried in locked cars and trucks that enjoy Federal protection against intrusion, and end up in mailboxes that are almost always on private property and/or locked.

Looks like it was an host misconfiguration, they fixed it after I've get in touch with one of them on IRC.
Some really good points here.

Wondering if you've corresponded with the founders about your experience? I've a car with FlightCar at the moment and I've found them to be really responsive. Just a thought.

Thanks for the first hand feedback. What do you mean about 'not add new emails to your identity information'? I'm OK with missing out on the latest & greatest features/products. I also don't really care about Google+, if that's what your third point was talking about?
Ideologically I feel like every tax funded researcher (i.e. the vast majority) has an obligation to make all his work publicly accessible.

Change will happen once open access journals get A level status. If there's enough that are sufficiently peer reviewed a simple legislative fix (for state funded/supported education which is the case for most forms of education) would be to treat open access publications preferential when it comes to hireing new academic staff.

As someone with the long term vision of massive changes in education towards e-learning I think the way to attack this is to actually couple OA initiatives with sites like coursera, edx etc.

How deep are the Buffet/Gates pockets, maybe just buying up a bunch of content and freeing it might be the easiest path.
In theory, yes.

Was playing with Backlift not too long ago (They have nice Backbone [1] and AngularJS [2] tutorials using their backend) and it looks promising, but I haven't got the chance to really do a comparison with Firebase (isn't it also a YC company?)

What are the differences between Backlift and Firebase (or Parse)? What are the value add features? What things are done differently / better?

Note that we do sibling call optimization per LLVM, and you can use trampolines like Clojure does. Sibling call optimization, most notably, includes all self-calls. This means that calls to the currently executing function in tail position will be tail call optimized, if there are no destructors in scope.

The biggest problem here is ABIs: you have to use Pascal calling conventions instead of C calling conventions. It's also difficult when you have destructors: there are not many tail call positions when destructors are in scope.
It wouldn't surprise me if various enforcement agencies viewed encryption as sufficiently suspicious behaviour to arrest/investigate you for some kind of "terrorism" charge anyway.

> The way they could take over the network is by crafting a new blockchain, forging fake transactions or even claiming that they own all bitcoins. If they solve blocks faster than the rest of the network, soon their malicious chain would become longer and therefore accepted by all clients! Clients always trust the longest chain because it takes the most work to make, so you would have to control most of the mining power to fake anything for long.

This is incorrect. Having 51% or more of the computing power of the network doesn't allow you to replace the whole blockchain (there are checkpoints, and it gets more difficult as you want to replace a bigger part of it). You also can't forge new transactions, since transactions need to be signed by the sender.

Basically the only practical attack (assuming no serious bugs in the clients) is a double spend: they could pay out of their own wallet a sum X to a third party, the third party checks that the transaction has Y confirmations (remember, as Y grows, it gets more difficult to pull this off), they receive whatever they've bough from the third party, and then they start pushing a different and longer block not including the transaction.
Knowing your BATNA (if I search long enough I can find another person who is willing to sell me the same car for cheaper) can make the difference. That's perhaps the most useful lesson I learned from GTY. In this kind of "competitive deals", if the deal is ever done it will favour the party which held the hardest position; knowing your BATNA helps you stay hard if you have a good reason to do so, even if you're a soft person. It's a bit like the difference between a well calculated poker bet and a complete gamble.

The ability to sell an item for x USD is not one of the "things" you can do with it that contribute to intrinsic value. Let's put it a different way; if the market value for a bitcoin was $0, what could you do with it? Compare that to an apple. If the market value for an apple was $0, you could eat it. Thus (unless someone has a clever use for bitcoins outside of currency) an apple has greater intrinsic value than a bitcoin.
Ask HN: Why is Bitcoin so volatile?

Is this a manipulation by the large marketplaces such as Mt Gox, etc?

There's already an almost identical post on the front page.

9/10 exchanges are down due to DDOS. All Mt.Gox data is about an hour old due to lag. The price you're seeing is not reflective of the actual value.

The weekly average is still 5x higher than the weekly average a month ago. Is that a crash? No.
What is missing in this entire experience is that FlightCar did not do a good job of reassuring customers, and the hassle after the fact (checking with dmv, worrying about tickets, etc) does not seem to be a very pleasant.

First of all, some people are very protective of their cars. Handing them over is a sign of trust, and FlightCar has the responsibility to make customers feel comfortable, which they did not do.

To put it in perspective, imagine that you rented out your room. Your tenant decides to put all your stuff in a garbage bag and put it in your closet, and left it there when they moved out. How would you feel?
All understandable points. I'll put out a couple of suggestions. Keep in mind that when troubleshooting, these are all guesses. They're not intended to imply that you don't have a problem. Also try to keep in mind that there may be some small detail you've overlooked that is causing the behavior you're observing. If you're dead set on insisting that the behavior happens the way you've described and there are no other possibilities, then you should stop reading here.

As troubleshooters, we often try to fill in the blanks with what we perceive as small pieces of missing information. This isn't an individual assault, but rather learned behavior. I'm damn good with a computer, but my #1 rule of troubleshooting is to assume that any "truth" about what I've observed can be invalidated through empiricism.

Enough hedging, let's see if we make any progress in troubleshooting the problem you experienced :) What we know so far:

* Pressing the TAB key results in an email being sent

* Other users report that pressing TAB doesn't send the email

We accept these as truths, but with two caveats: 1) they may be disproved or refined at any time (we aren't sentimentally attached to them, ego be damned), 2) there may be some additional information that is not yet obvious, so the list shouldn't be considered complete

What can we tease from this information?

1) Can you get the behavior to occur predictably? If you open a new compose window and press TAB, does the email send every time?

2) What is the normally expected behavior of TAB? In most web browsers, the TAB key is used to move focus from one form element to another. In Windows, the "focus" can move to buttons as well. In OS X, the focus navigation using TAB is constrained to text fields and lists by default, but can be configured to "All Controls" through the Keyboard preference pane.

3) What processes are available to intentionally send an email? That I am aware of, you can: click the send key, use the keyboard shortcut ctrl+return or cmd+enter (Windows/OS X). Use TAB to move focus to the "Send" button and press the spacebar/return/enter.

4) What small pieces of information might be missing? We've already ruled out browser extensions, so that's a good start. Try to think of any other software that uses global keyboard shortcuts or performs automation.

My pet theory (guess) would be that you're pressing TAB expecting that the TAB character is inserted in to the text field, but this is actually causing focus to move to the "Send" button. From there, a press of the spacebar, return, or enter key is sending the email. This is very easy to do when typing. If you can't regularly reproduce the behavior by a simple press of the TAB key, I'd say this gives this theory a higher probability of correctness. If you can reproduce the behavior by simply pressing TAB, then you can discard this theory.

Let me know if you have any thoughts on these items.
How would you audit a system like that?

You have all of the downsides of rolling your own (liability wise) and none of the upsides of using an IPSP (also liability wise), on top of that you'd have an auditing problem. (I presume 'black box' means 'box that performs a service that you can't open up to inspect').

What you are essentially looking for here is called type certification, but type certified hardware is on small to medium volume much more expensive than a service would be. And once you hit larger volumes you're going to be hooking up a much larger number of payment options and your 'black box' will solve only a (small) subset of your needs.

I don't see the advantage of this approach.
How To Find The Best Cofounder
Because a powerplant has one extra required component that a rocket doesn't- convert the reaction energy into electricity. Every known, engineered method doing that that we currently have is sufficiently inefficient that more energy is lost in conversion than the fusion reaction produces, which is why you get less usable energy out that you put in. It's easy to make energy from fusion, it's hard to get that energy in a usable form, which is what we mean by "break even". A rocket is not subject to that constraint, because the raw reaction products themselves, without conversion to any other form, are exactly what a rocket wants anyway.

I think you misunderstood. I'm not talking about Python throwing errors about the types of my variables. Like I said, I'm already quite comfortable with Python. I'm talking about Django failing to check whether my Django-specific code (e.g., templates) is valid, so that Python gives me an error message that appears to originate inside the Django codebase, instead of Django giving me an error message about the syntax of my template.

I've only briefly tried CakePHP, but IIRC its error handling was excellent.
