Yeah but that's what I don't want to do--because that makes Bitcoin just a USD proxy, not a currency and economy of its own. I'm interested in BTC as its own economy, but unfortunately the price instability and tendency of most users to exchange for USD in the end makes it impossible to explore that.

"If the brakes stop working then you're in trouble (and so is everybody within striking distance), but brakes failing due to a software bug that you induced is a thing that I've yet to come across. Most brake systems have mechanical back-up, and if all that fails you can still reach for the 'oh-shit' lever, aka the emergency brake. Anybody that has ever had a master cylinder fail on them knows what I mean."

My Volkswagen has one of the electronic parking brake systems, so I don't have an ohshitlever. I have an electrically powered button that is probably useless if there's no power. I could always downshift, since I got the manual transmission.

In the future, I doubt most cars will have the old style mechanically controlled parking brakes.

Give it time. I happen to think that bitcoin is still stabilizing. Whether it will stabilize at an even higher price than it is now, or "crash" and stabilize at a much lower price, I think it will eventually stabilize.

Do you know how many Rails developers I've heard pissing on Flash or Java and its security vulnerabilities? Many - until recently. Now suddeningly these faults are an accepted aspect of Rails development. Really. I guess this more of a rant about how unfairly the Rails community (ie. dhh) has been on others, but now expects critics to look away while it happens in the Rails community on a weekly basis.
Bingo.

The only things I'd like from Coursera courses are:

* more that take 8-10 weeks rather than 6 weeks

* if the CS course happens to use a particular language then make it incredibly easy to get setup and provide downloadable structure for any assignments (the scala coursera course has that nailed)

* better estimates for # hours a week

In general thought the synchronous approach works perfectly for me and is the big reason I haven't yet felt the need to do any Udacity courses.

Model S is a nice car, comparable to a BMW 5 series. I think this is why people are buying it added with the fact it's an EV with one moving part. If green and unused weight was a customers primary concern then they would get a motorcycle or Nissan Leaf and not a sedan that can go do 0-60 in 4.4 seconds. My point is, I don't think they will be upset based on that reasoning. Maybe someone that already got a 60kwh might be upset and would have opted for the gimped range if it saved him $10k. As a 40kwh reserve holder, I am thrilled to be getting a 60kwh, I'm not concerned about the extra weight.

There's lack of payment options with "essential goods & services", like groceries, but what's your point? Any new currency, especially digital, doesn't start with supermarkets, because supermarkets tend to be owned by large corporations that are not first adopters.

If bitcoin will become a major currency, it will have to have a phase where it cannot be used in general and only with a small number of companies. That's not evidence that bitcoin will not become a major currency, it's evidence that it hasn't yet, and nobody claims it has.

Once you have an agreed goal, you can investigate techniques for reaching it. But some of the disagreements are over what the goal should be.

The "invisible interface" people's goal (in strong form) is to dispense with explicit interfaces as much as possible, seeing them as just friction between what people want and what the computer can do. One version of how to achieve that vision is AI-heavy, relying on people saying what they want in natural language and software like Siri figuring out how to give it to them.

The rough opposite is more of an interface-centric approach, where the goal is to actually foreground the interface as an explicit point of interaction, and have it present a logical and coherent set of controls that, rather than being invisible, makes clear "I am an interface and I do X/Y/Z".

Detailed information about things such as eye tracking speed seems to me like it'd be most useful in doing the actual implementation, once you have a rough idea of its purpose and use case. It's certainly possible to do scientific investigation of the more general question as well, but it requires more than micro-scale laboratory tests.
Considering eBay owns PayPal[1], it's unlikely they'd want to promote any competing currency.

Or in forth, which uses reverse polish notation:

30 2 power 2 +

(a constant gets pushed onto the stack. functions like "power" and "+" operate on the stack)

So this also works:

2 30 2 power +

Although I don't really use it anymore, my calculator (an HP scientific calculator) also uses reverse polish notation, so you can keep intermediate values on the stack, and do complex calculations without using parentheses at all. This is also good for keeping people from asking to borrow your calculator in math class. :)

What is the syntax that you posted? It looks just like RPN in reverse. Ok, that was a stupid question. I just figured out that is just "polish notation." It must keep a stack of operations that don't have their operands yet.
I'm curious if you have any experience working with them, and which you'd recommend?
Specifically that the security releases included changes to the way that ActiveRecord works (which were unrelated to the security issues).

As a consequence, their search queries were scoped differently than what they had intended. So their choice was roll back the security release, or modify their app to accommodate ActiveRecord's altered behavior.

5 Terrifying Things To Know About The HR 933 Provision
Then one day, some highly motivated attacker will come along and discover the other very interesting property: that the work needed to attack Bitcoin scales linearly with the work needed to use Bitcoin. As soon as a successful attack is announced publicly, faith in Bitcoin will be shaken to badly that nobody will ever want to use anything called "digital cash" for a long time.

So the real question you should be asking is, "Who would benefit from a Bitcoin failure, and could they amass that much computing power?"
With regards to your use of the word 'worthless' relating to the Coursera certificate of completion.

Many university courses aren't significantly different to Coursera so I think that if the courses keep up their standards and enough people have knowledge of them then it is possible that that certificate will not remain worthless.

We were discussing Coursera at work last week and I think that if a job candidate appeared with Coursera completion certificates on their CV then it wouldn't be looked at unfavourably.

Very insightful.

I have finished six coursera/udacity classes so far. The last one felt really hard, not because of the material or the teacher. I wasn't really interested in the subject. It was something that I thought it would be good and useful to learn, but I was not passionate about it. So, last night, I finally finished the course, but it wasn't easy.

So really the questions that I should be asking next time is which class I really feel passionate about, and/or how do I become passionate about the class that I am taking.

I don't have to. The fact is, no one prices their goods in BTC. Its absolutely ludicrous to price goods in BTC in the current market.

I think BTC has utility as a currency for exchange however. But on that side, you don't want to be in the position of hoarding BTC. You hoard dollars, and then use BTC to transfer dollars between people. Services like Bitpay allow you to keep most of your money in hard cash.
Logically speaking it doesn't make bitcoin a USD proxy, a non-currency or "not-a-economy" as you claimed. Fixing the bitcoin price to another currency is a good solution when the value of 1 bitcoin is changing rapidly, as it would take a lot of work to adjust it daily. Besides, you can fix the price to the average of multiple major currencies (like average of euro, American dollar and the British pound).
FWIW, it looks like they just switched out some textures and put an overlay on street view. Maybe one day of design work and one day of dev work, at the most (and a half hour meeting with their bosses, I guess). I don't really find this particular prank that hilarious, but it certainly didn't cost anyone hundreds of thousands of dollars.
I've shared my sentiment here before on why I'm not going to use Rails anymore. Imagine having your code working fine, and you update a MINOR version 3.2.x - and your ORM starts returning results that it didn't used to.

Heh.

Not worth the heartburn. I've switched to a saner, more tought out framework. Rails is gorgeous, but not safe to use for any serious systems where you're in a small team.
Money != Currency. Gold and Silver are Money. Bitcoin and USD are currencies. Huge difference.
I have said this multiple times in previous discussion threads, but everywhere you look, all indicators show that Bitcoin spending is increasing: https://news.ycombinator.com/item?id=5296889
It is incredibly easy to buy and sell Bitcoin options: icbit.se is just one of several reputable derivatives markets that focus on Bitcoin. So yes, if you are completely sure this is a bubble, it's easy money...right?
Same for me.

I also find the assignments/exercises on the courses are first class and that's where a lot of the learning comes in especially when backed up by discussion forum activity from other students. Watching the videos on their own doesn't really appeal to me.
Cloud 66 adds two factor authentication to all accounts
Neat!

I made some money in the 80's by drilling holes in a very specific spot on a package moulded around the chips in Philips 27 MC rigs. They were originally intended for the US market and had 40 channels, the modifications reduced that to 22 channels. But the switch still had 40 positions, which was a giveaway that this was a mod rather than a redesign. I figured out where to drill in the plastic package that was moulded around the original chip (and to what depth!), and charged 50 guilders for the mod (which took about 5 minutes with an appropriately designed jig).

Fun days, all I was after was to destroy that extra circuit so accuracy wasn't too important.

As far as the SX is concerned the wp article you linked states fairly explicitly:

"If testing showed that the central processing unit was working but the FPU was defective, the FPU's power and bus connections were destroyed with a laser and the chip was sold cheaper as an SX; if the FPU worked it was sold as a DX."

If they needed more SXs and used their laser on the die then I guess that was a pretty hard to reverse operation :)

Rails became worse than the frameworks and ecosystems it laughed at in it's younger days.

Remember - Rails is Omakase - meaning literally 'leave it to someeone else' - food for thought indeed.
No matter your stack, you are occasionally going to have to deal with security vulnerabilities. Thankfully, rails at least is quick to issue releases which address security vulnerabilities. Back when I was working on java applets, I remember security issues in Java plugins which would persist for weeks, months, or even years.
Every form of currency suffers this problem in the beginning.

There are really only two ways around it: easy convertibility into another currency that people already understand, or direct use-value of the currency commodity itself.

It's a question of social inertia. It's too early to expect people to think in BTC.

Ouch. Did you run the build with multiple jobs? (Parallel builds have been a bit messed up because of fetching the bootstrap, but you can coax it into working.)
As ever: Bitcoin is a lovely medium of exchange, a horrible medium of account and hence a purely bubbled store of value.
As a commodity, gold always had an intrinsic value separate from its value as a currency. So if the authority stamping the coin disappeared, I could always melt down the gold and sell it as a simple commodity.

In the case of bitcoins, they do not have a utility outside of their use as a medium of value exchange. You can't really melt them down and use them to make jewelry, build cables or any of the myriad other uses that gold has.
The notion of "money" is quite well defined. You need 3 properties:

1) Store of value. Much easier to store gold/USD/Bitcoins than the food you will need in the future.

2) Medium of Exchange. Can be used to exchange for real goods, thus avoiding the headache of barter.

3) Unit of Account. e.g. is easily divisible.

Bitcoins aren't great at #2, but gold is terrible at #3. If bitcoins prove to be a lasting store of value, then it will almost certainly be more "money" like than gold.
A currency can have an economy fully its own and still have prices pegged to another currency. There is a lot of historic precedent for that. You act like its an abhorant practice. Prices will stabalize as the BTC price approaches something more workable on a global scale, like $21,000,000/BTC
No idea where they got that number, or what a "responsive designer" is (answers phone calls quickly?). This myth has been debunked long ago.

"Currently, hoarders are the ones benefiting from BTC, but no one else is."

That's not true, BTC has many benefits to bitcoin users. There's plenty of bitcoin-only services, but more importantly, it provides freedom for many people who are facing government regulation. In the long run, bitcoin enables all kinds of innovation (good example is reddit's bitcointip service, which wouldn't really exist without bitcoins).
