The ancient remains of a great and enormous basalt structure, hmm? Now where have I heard of that before... Ah, yes!

"And before the day was done Carter saw that the steersman could have no other goal than the Basalt Pillars of the West, beyond which simple folk say splendid Cathuria lies, but which wise dreamers well know are the gates of a monstrous cataract wherein the oceans of earth’s dreamland drop wholly to abysmal nothingness and shoot through the empty spaces toward other worlds and other stars and the awful voids outside the ordered universe where the daemon-sultan Azathoth gnaws hungrily in chaos amid pounding and piping and the hellish dancing of the Other Gods, blind, voiceless, tenebrous, and mindless, with their soul and messenger Nyarlathotep."
- H.P. Lovecraft, "The Dream-Quest of Unknown Kadath" (and alluding to his earlier "The White Ship")

Perhaps we should seek the other Basalt Pillar of the West in the Dead Sea.

I hope you're right, but actions are what counts.

As to the rest, I am seriously sick of people using the law as their own weapon against others. A tax break here, a special rule there, and we as voters and consumers lose because there are more law on the books than we need.
A currency set up to be deflationary and swings at 50% daily? This sounds like a great investment - I also have a slot machine I'd like to get you to invest dollars on.
I'm not sure if this is help or stating the obvious but I've found that consciously making the effort to remember stuff and record it in my mind goes a long way to staying organised on this front. I found the best way to start was with people's names, when someone says "Hi, I'm X" I try to response with "Hi X, it's good to meet you, I'm Simon". Just this simple repetition of their name goes a long way to committing it to memory, if you can say it a couple more times in the conversation you won't forget it again.

This wasn't always the case. In fact the government argued the exact opposite for years.
The 50% drop is larger than usual, but 30% falls have regularly been seen during the current rally, and they recovered as fast as they occurred.

Furthemore, the trade volume in Bitcoin is unexceptional.

Edit, 10:56PM CET: It went down to ~$100, and it is already back up to $180. I predict another drop in the next few hours, then a recovery around at least 200. That's the usual pattern.

Thank you sillysaurus, I was about to go buy BTC at 270 to a local guy (I don't have any other way for buying bitcoin here). I forgot to check the price again, but I didn't forget to check HN ;)

I think part of the issue is that it's kind of a slow news period right now. There are not a whole lot of really exciting other stories hitting HN's front page so far in April.

You must be new to bitcoin. Take a look at what the price did over the Summer of 2011.

The Day the Replication Died
Other exchanges tend to tail MtGox.
On the contrary this is just the most pronounced in a series of recent coordinated DDOS / aggressive selling attacks designed to (successfully) inspire panic. The attackers unload their bitcoin before the price gets smashed and presumably buy it all back again from frightened speculators.

If anything it might be a positive sign for bitcoin that the attackers are keen to acquire it!

On another note, mtgox.com the main exchange is shockingly unfit for purpose. If real markets could get 1 hour behind in transaction processing because of a spike in volume it would be the end of capitalism as we know it. I hope a more able exchange arrives soon.
Im sure when calculators first came out there were people who didnt trust them either.
It is not clear to me why Mt Gox did not suspend trading when the order lag reached 20 minutes and/or once the webpage began returning "Database error" messages.

A lot of people are commenting that this will be remembered as the day btc crashed the second time. In my opinion a more accurate characterization would be that today is the day that Mt. Gox crashed.
Awesome discussion. The reasoning on my assertion is as follows:

The description of the pile of rocks, it matches the description of ballast piles outside of ports on the Mediterranean and larger inland seas.

Ship technology from the time [1] tended to flat bottomed and top heavy boats.

Ships in general, but merchant ships in particular, use ballast to adjust their buoyancy so that they sail per their design. In the case of merchant ships ballast is always something of low value and easily removed.

When adjusting ballast without pumps, solid ballast is easier to load on and off than either liquid ballast or sand ballast (which would require shovelling).

In terms of value to pound of ballast delivered, random basaltic rocks achieve excellent efficiencies.

It's certainly possible that this is something else entirely. I don't think we'll know until they do further research, until then it would be fun to hear other's reasoning on what they think this "structure" represents.

correct in a sense- the US dollar is backed by the full faith and credit of the US Government, nothing more. Would I still have that faith in the US $ if the government did not collect taxes / did not seem like a stable entity? Probably not, but your point is still valid
"GCC actually does do TCO in some cases (I'm using 4.5.3, and tail-call elimination occurs with -O2 and higher)."

Ask HN: How much have you made in the Bitcoin game?
Then any system which fulfills the following criteria should work:

- good (safe, knowledgeable, rested) taxi drivers
- taxis in good condition
- a sufficient number of taxis on the road
- a reasonable price to the customer
- and a system to handle complaints

It seems to me that medallions actually fail on some of these points.
Instead, it would be worthwhile to:

- license drivers, not medallions. Non-transferable right to operate.
- license taxis with regular inspections
- use technology to track cabs
- have the city run a centralized, mostly web-and-touchtone based dispatch
system
- and adopt suitable regulations to avoid feast-or-famine at the airport,
downtown, and that socio-economic region that the cabs tend to avoid
So then it turns out that your small group doesn't matter as much as you think it did, and it turned out to be smaller than you thought. That is, as they say, tough.

Look, just because you want something to happen doesn't make it viable in the long term, and someone who demonstrated it was not viable in the long term doesn't become evil because they sped that process up. If they actually burned down all the other coffee bars in the process, that's one thing, but they didn't. They convinced folks to be satisied with something else.

You have literally just said "What if the remaining users are not enough to support a viable product I liked".

Then there aren't enough to support a non-viable product you liked, and that wouldn't be any different no matter how it happened. The only difference is it happened in 5 years instead of 50.
If the other way was still something that satisfied people, one would assume others would eventually revert to it.

All drugs have some set of side effects, and usually very badly effect some small percentage of the population that won't know until the take them.
Does this alone make releasing any drug evil?

If not, can we please just move the discussion along into social utility territory, instead of the "well, it hurt someone somewhere, so it's evil" stuff?

Contrary the misquoting a few parents up, the statement was "don't be evil" not "do no evil". This is an attempt to be guided by doing the right thing, not an attempt to ever avoid harming anyone. Basically, whether someone is being evil or not is not about you, it's about them.
Depends on what you mean by "access to support."

My company, and several of my customers with whom I've discussed this issue, spend a significant chunk of money on Google Apps and related Google services. We do get a customer support #, but all that means is someone answers the phone.

I'm not sure we've ever received actual support from them. We have trouble tickets for significant, documented issues that have been open for YEARS. The official answer is that someone from engineering will look into it and get back to us.

We're looking into ways to reduce our dependency on Google services, but of course it's a challenging and time-consuming endeavor to migrate away.

Changing the sentences adds bias. Maintaining the author's intent is important.

Generating news highlights from lots of sources might be cool as computer generated content. But rewriting an author's story in new words is not adding value it is just ripping them off.

What an intersting proposal.

The car dealerships should technically oppose it, because what this creates is a hole in their monopoly. It's not a big hole, but its enought to drive a car right through :)

Also, the proposal also creates another monopoly for Tesla. Until there is another fully electric car maker, Tesla is the only dealership is town. If Tesla can generate enough sales. Who can take them on in Texus without offering a fully electric car? If Tesla can't generate sales, then who cares about electric cars.
What? Of course it doesn't say anything like that. That was obviously an extension of your statement; enabling any car manufacturer to sell directly to customers would be a diametral opposite to what dealership laws intended in the first place, and my comment was supposed to inform you that there is indeed a little sparkle of sense and justification in dealership laws.

But you obviously lack any insight into the topic at hand and are just feeding off your "more exceptions!11" reflex. That does not a good discussion make.

ComiXology Reverses Ban On The Latest Issue Of Saga, Says Apple Isn’t To Blame
I came to design from engineering via usability. Usability gives you metrics you can qualify your UIs with, just like you have for your code. Time on task is like execution speed for people. Information efficiency is like lint checking for content.

I started with Jef Raskin's _The Humane Interface_. Chapters 1-4 cover the essentials about testing and usability and efficiency, and then Chapter 6 from 6.3 on, and you can skip the rest.

Then, assuming you understand semantic HTML, you can take efficiency and semantic HTML and understand information architecture and 2D content layout. Robin Williams' _The Non-Designer's Design Book_ and Jan V. White's _Editing by Design_ can teach you effective and attractive positioning of content on a page or on a screen. The principles are all the same.

From layout you can get into visual design through things like dashboards (Stephen Few's _Information Dashboard Design_) or other "practical" subjects without ever getting into becoming an actual artist.

If you want to get more into visual design, I've given out a few copies of David Kadavy's _Design for Hackers_, and it's supposed to be good, but I haven't read it. The best way is really to take some introductory visual design and art classes. Check your local community college.

If you want to get more into user experience or interaction design, Dan Saffer's _Designing for Interaction_ is often cited as a good overview of the practice of interaction design, but I haven't read it, either.
Thanks for the link, but this is something different than what I was thinking about.
No, it's not just backed by mere consent. Try not paying your taxes. It's backed by the people who will make good on those promises by force.

It is true that nothing absolutely guarantees the value of the US dollar in the strongest absolute sense, but that's true of absolutely everything. There are no absolute stores of value that are guaranteed. (This bothers a lot of people, but it's true.) But there's a qualitative difference between being backed by the US government and being backed by nothing at all, a very substantial one.

I would point out that one of the usual things touted in BitCoin's favor is precisely that fiat currency can be arbitrarily manipulated by governments; this is possible because the backer of a currency can manipulate said currency, in a way that I cannot. On the other hand, I can arbitrarily issue and manipulate JerfDollars, but nobody takes them. (Not even me.) One of the things BitCoin tries to solve is precisely that people don't like what's backing the US Dollar, and they'd rather try something else. If it were indeed a backingless currency precisely like the US Dollar, the entire point of BitCoin goes up in smoke; what's the difference between two backingless currencies? Not much. In trying to claim that the two currencies are identical in this fashion, you may win the battle but you lose the war entirely.
if you have functionality class/ID, do you really have separate concerns or do you just have moderate/loosely coupled concerns?
A contraire. There is a long debate over subjective vs. objective value. Your argument falls under the category of an objectivist's arguments.

A simple example of subjective theory are two identically optioned vehicles isolated to one difference:

Vehicle A: Silver Metallic Clearcoat
Vehicle B: Sunny Yellow Clearcoat w/Orange Flames

Under an objectivist framework the two must sell at the exact same price because the are intrinsically identical save for the cosmetic difference.

The US Government could pass a law making bitcoin legal tender much the same as pieces of paper or the majority of circulating money that is nothing but electronic bits also.

See J. orlin grabbe's essays if you prefer to hear about it from someone else.
I stand corrected - this has happened once before in Bitcoin's history, so apparently there have been two times in which Bitcoin price changes have been suitable HN fodder.

Though, now, it's a $1B+ valuation and in the New York Times.
> I was doing research and apparently I was wrong too, depending on a definition of fusion breakeven (which I was unable to find) Care to explain what is yours?

Fusion break-even means the reaction produces more than or equal to the power required to initiate it. Apart from stars and weapons, it has never been achieved.

http://en.wikipedia.org/wiki/Fusion_energy_gain_factor

Quote: "The fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1 is referred to as breakeven."

> If you achieve even smallest amount of fusion, technically you have more energy than you started with.

Yes, but with serious problems. One of them is that you have to continue providing more power than the reaction creates, in order to keep the reaction going. This means the overall available power is less than the input power. The reaction is using up much of the power to sustain itself, and that power can't be applied to another purpose. So even though technically there is a lot of power present, it cannot be applied to any purpose other than energizing the plasma. This means the net available power is less than the input power.

This is a bit hard to visualize, so let's say that we have 1000 watts available to apply to some ordinary purpose, or to sustain a fusion reaction.

We discover that the fusion reactor requires all 1000 watts to keep its plasma activated and fusing, but the fusion reaction only produces 250 watts. So, even though there is 1,250 watts of power in the system, 1000 watts of that is required to sustain the plasma in its fusing state and is therefore unavailable. That means only 250 watts is available for any other purpose.

Hence the importance of break-even. :)
You actually had it right the first time—"bears repeating"

I wonder if the value would ever fall to precisely zero. Mightn't they still have value as a novelty or collector's item? Like, "Hey, a Bitcoin! I remember those... sure, I'll buy one, just to say I have one." It's unfortunate that you couldn't mount it in a decorative frame, though.
It tells you which song it takes the line from as it does it.

Do you have any evidence at all of a coordinated attack against Bitcoin, or is this just an unsubstantiated conspiracy theory?
Love that term "elite overproduction". Never heard it before, but it makes sense to me. It definitely seems to describe a trend we see in this country. The political class, including lobbyists, consultants, pollsters and assorted hangers on, is so bloated it can only be fed by diverting resources through corruption and stagnation in the political process. This is something libertarians tend to warn about, while getting dismissed by partisans from both sides who only see it as a problem in any way when the other team is in power.
I wasn't using "scared" literally, and I assume the person I was replying to wasn't, either. Web sites aren't generally actually frightening. [Insert your own punchline here]
There is a flipside however, for those who think deregulation is the answer.

In Amsterdam, the taxi market has been completely deregulated. You do not want to get a taxi there unless you order it from a trusted source, and even then it's ridiculously expensive.

And you don't want to try to disrupt that market unless you have good organized crime connections...

And then people wonder why there are so few women in tech. People like you are part of the reason.
Anyone know what their systems look like? What hardware, what databases, OS'es, what language is their order matching engine written in?

And do they have any systems & developers on staff who know what they are doing?
I haven't tried it yet, but if I was going to sell BTC for USD I would give this one a go: https://fastcash4bitcoins.com/ They only buy BTC, and it's a fixed price instead of an of exchange.
It sounds like you have trouble being assertive. At the end of the day, you have to fight for your own interests. Assertiveness is the fine line between courtesy and self-preservation. Being assertive means you MUST stand up for yourself to protect others' interest from overriding your own. It's a tough duality that most people aren't naturally good at. Generally, though, standing up for yourself in a non-aggressive manner earns a lot of respect. I heard this great quote that really helped me dealing with issues of my own passiveness:

"People will only walk on you if you lay down on the sidewalk and let them."
I definitely wouldn't argue with the fact that we have to think what we build, design carefully, etc. However imagine the world with massive test coverage that provides instant regression testing and the world without it. What would you choose?

We do have thorough peer reviews, that's what Phabricator is for and nothing gets in without passing a code review.

Some more comments.
1. True, but you have to hit a combination of a test bug/feature bug to let the feature bug slip through
2. Also true. And we had to deal with those type of bugs. When the area is tricky (transaction log rotation, quorums, etc) we sometime have to the extends of proving things formally.
3. Very true. And scenario based testing will only get you this far. Receiving customer feedback is critical for that. Obviously SAS has advantage here.
4. Everything is a tradeoff. We definitely design/prototype hard features before we build them

I think the right way to put it "Once you put yourself on the scale between chair legs and a space ship, you should choose how you run the engineering process".

Nice article. You might want to change this sentence though:

That last part radiates an inconsistent signal :-)
What evidence do you have of this claim?
Not sure you can consider that an intrinsic value. I could be wrong, but my understanding of intrinsic value is essentially that it is the value of an item when the market value is zero. The bitcoin protocol does you no good if the market value of a bitcoin is zero.

You do present an interesting conundrum though.
No - this is not universally true.

e.g. Google Apps for Business is a PAID product that is not advertising supported.

The sales literature says "Count on our 24/7 customer support" - http://www.google.com/intl/en/enterprise/apps/business/benef...

Unfortunately, per my post above, customer support is basically every bit as lousy for customers of paid products as it is for users of free ones.
