There won't be a liquidity crisis only if all people dealing with bitcoins will accept to lower their prices in response to the deflation of the currency - this would include workers paid with bitcoin. Not very likely. Would you accept to be paid less and less every year (month, week...)?
The rule of awesome
On June 27, 2006, a monitoring well, which most people (myself included) would probably never notice among the carefully manicured flowers and shrubs, registered 85,000 µg/L of TCE, the same toxic industrial de-greaser that newspapers reported about in Google's buildings a few weeks ago. For the sake of comparison, the federally-mandated limit for one liter of groundwater in micrograms is pretty far from 85,000. It's 5.

yes, it's an internal tool for several people at the moment. your characterization of "real-world websites" is somewhat misguided, I think. JITs, by design are targeted towards compute-heavy applications built for the web platform, not "typical" websites. so to say they will have little effect on websites is probably accurate, but misplaced. mozilla is building Firefox OS, where these JITs will play a critical role in smoothness of interaction and almost certainly fewer cpu cycles on mobile devices to save battery life.
I'm not sure which builds you compared. Firefox 22 is currently in Aurora phase, and Firefox 21 is Beta. It does seem like there's been a regression in the aggregate scores.

Thanks for bringing it up, though, that should be looked into. Have you submitted this regression to bugzilla.mozilla.org? If not, I'll create one for it to be looked into.

Just for kicks I ran can-attribs on a pre-Baseline and post-Baseline build of firefox nightly on my macbook, and the scores received a modest (about 2-3% average) bump from the landing.
One of the things you need to remember

I have been building and architecting very rich web applications before most caught onto this web thing. I was an original tester of XmlHttpRequest back when it was a safe-for-scripting ActiveX "abomination". I recently made a ridiculously full featured stop-motion recording studio -- in the browser -- for my children after they were enamored by something similar at the Science Centre.

And JavaScript performance has not been -- remotely -- an issue for a long, long time. The facets that make these apps powerful are technologies like WebGL, Canvas, SVG, CSS, and so on. Things that I wouldn't imagine doing more than simple orchestrations in code.

People use JavaScript performance on a completely artificial benchmark like Sunspider as a proxy for real-world browser performance. Yet it is at most a minor correlation, and has incredibly little to do with causation of a good experience.

If you think I'm joking or overstating, turn off the JIT in your browser and use it for a day. Is your experience devastated? Can you even tell the difference?
Ha - I wrote about this at length years ago, even photoshopped little examples:

First time I'm actually happy for building something with Servlets (have a feeling I'm the only one here that uses it as the go to framework for hacking something quickly, I'm an old man), it's indeed dead annoying for REST services, but doable, and blazing fast. The question is - when does my productivity starts to be more important than performance (I think 99% of the lifetime of anything I'll ever build is the first and not the latter).

I'm very surprised to see Play-Scala is not in the same playing field as other JVM based frameworks, had a lot of hope for it, I hope TypeSafe will take that into consideration...

Node.js is the biggest surprise for me on the good side, I think it changes my plans a little as for what to learn next...

Thanks for a very valuable study, this is great

Not necessarily. By investing you take your destiny in your own hands: you deflate your savings and also collect profits. It is not a given that those just sitting around will profit more from inaction, but it is true that you make them richer too. Well, I can live with that.
Can someone pro-bitcoin provide a counterpoint to the deflationary spiral criticism? I don't have enough of an understanding in economics to think of one.
I don't have any sources, but I suspect you are correct only up to the certain point. People are largely ok with mental illness which doesn't impose on them. Depression, yes, Schizophrenia, no.

My impression is that if the condition involves quiet angst, everyone will sympathize -- but if it's about real heavy duty craziness, no one wants to hear about it (or look at it or think about it, etc.).
Talk about goalpost-moving. First you ask for apps that benefit from these kinds of optimizations. Then someone gives you an example and you say it isn't important because it probably doesn't have many users?

That's a catch-22. Apps like that can't have many users because the improvements they depend on aren't widely deployed. However, those improvements will never be widely deployed if people persuasively argue against their importance using evidence like a small user base...

Dark Ages would imply that progress was set back significantly by some catastrophic event (ie: the fall of Netscape).

Some of us would argue that JavaScript itself was that catastrophic event. No, really -- I'm not trolling. It's no longer reasonable for people to deny that JavaScript doesn't lend itself well to optimizing run-time performance.

These Herculean efforts are impressive, but perhaps it's time to fix the language, even if that breaks backwards compatibility.

You're not wrong, but you're overlooking a bunch of things. Suppose you grew up in San Francisco - does that count for anything at all, or should you be subject to the same economic headwinds as people who just arrived? What about the costs of relocation and re-establishment elsewhere? As someone who has moved several times in search of opportunity (which is how I came to SF, in fact), you need a minimum of about $2,000 to move and get through the first month or two, and that's assuming you have no dependents and are reasonably street-savvy. Indeed, I'm underestimating that slightly because I've always moved to places with fairly high levels of density and moderately good public transport. If you move to somewhere that you need a car just to get around, then those costs are a lot higher, not to mention the opportunity costs of the time you now have to spend driving. If you move somewhere where you have no connections you're at an economic disadvantage fora while until you can build your personal network, especially if you don't have an obvious marketable skill.

At bottom, the problem is that the people who are in the most tenuous economic position are the least likely to have the skills and resources needed to just up and move somewhere else. It's true that subsidies do display other people who would like to move to SF and could afford it better, but they don't have any right to move there either. In general I'm strongly in favor of efficiency, but I think you're over-discounting the economic value of cohesive communities and internal economic diversity. Also, you're overlooking another alternative, which is to loosen constraints on development and allow the city to build upward more. Earthquakes are not that big of a limiting factor, considering that large parts of SF consist of two-story housing...a great deal of which is seismically unsafe compared to more modern apartment buildings of 3-6 floors.
How does this compare with developer time? It sounds like you spent more time tweaking the Naive Bayes than you did with the black box SVM, with the same results.
This only works when people are separate enough so they have an individual silhouette. If doing length of line tracking however, it becomes much more tedious, with edge detection necessary and such. Also, if using a 360 camera, this becomes more complex, as a person in the middle blob shape would be completely different from a person at the edge. I am aware you can use a filter, but it cuts out some area sometimes.

This is a surprisingly hard problem that I've explored before. Feel free to email me about it!
This is certainly good news for HN, more than a few times I have been misled into thinking a pages.github.com submission was an official github announcement.
The problem is that they increase in value, to a degree that the individually rational choice is not to spend them "now". The babysitting coop coupons were effectively subdividable as well: participants could have taken the initiative to say "I'll provide two hours of babysitting for an hour coupon" or "I'll provide 15 minutes of babysitting for 1/2 an hour coupon".
[Edit, for elaboration]
That would be rational when the value of babysitting in the further future (e.g. Valentine's day) exceeds the value of babysitting in the nearer future (e.g, Feb. 11).
Kill them, and only kill the people who would rape or kill innocent people or anything to that degree of crime.
MassChallenge 2013: 242 Entrants
That's completely bogus.

The average CEO is running a business that won't exist in ten years, and doesn't earn more than six figures.

You're talking about an extreme minority business group, a few hundred individuals are used to skew that stat to the moon. It'd be like comparing Single A baseball players to the top 100 paid players in the MLB; or NBA vs the development league. And even that doesn't get you close to the real exaggeration in the CEO stat.

There are over 20 million businesses in the US, none of which are Fortune 500 companies that always are used to abuse that CEO stat.

The average CEO is not earning $15 million per year (median income is $50k+, mean is over $55k (was $60k in 2004)). Indeed, how can the average CEO earn that much, when only a few dozen in the entire country earn that much?

Subdiving does not increase the overall supply of Bitcoin though. There would be no way in the future to obtain Bitcoin, except by taking it from someone else. Or someone else's hoard, as the case may be. (This is at least briefly touched on in the article)

This is also covered in the book "Debt: The First 5000 Years", when gold-standard and silver-standard monarchies had real problems keeping money in circulation due to the effects of merchants' savings and overall finite supply mixed with the large demand for coin in the Orient.

>>People don't become homeless because of poverty or a regressive tax code, they become and stay destitute because of mental illness and addiction.

That's really handwavy. When we get Star Trek level translation, or perfect specs, or devs decide to sleep all day and work all night (because who needs a family?).

Every very-large business I know of has offices and teams in other countries, and it works best when they're "just" another office. Branch in SF, branch in NYC, branch in London, branch in Chennai, branch in...

When you turn to other countries to grow your business, you can win; when you turn to other countries to replace the workers you built your company with you usually lose. IMO, YMMV, etc.

A great post from my co-founder Claudio. How are you doing with your confidence?
Bitcoin can't be debased.

a. That's a bug

b. That's a feature

They certainly were designed to be that way, and that was intended to be in sharp contrast with the conventional way currency is managed.

A more sophisticated argument about bitcoin might go this way:

a. Bitcoin provides an alternative that is both a useful experiment and is edifying in a way that may help keep the managers of currency systems honest.

b. Bitcoin is like releasing an uncontrolled nanotech experiment into the environment that could turn all our money into grey goo, and governments better put in place measures to prevent and eradicate experiments like this.
Very nice. Kind of scary the power of open source and how quickly competitors can spring up these days
This example always amuses me because Krugman guilelessly puts forth the case for central control while glossing over the results:

>>"But eventually the economists prevailed. More coupons were issued, couples became more willing to go out, opportunities to baby-sit multiplied, and everyone was happy. Eventually, of course, the co-op issued too much scrip, leading to different problems ..."<<

Of course, these different problems are just ignored. Krugman never seems to want to discuss whether these new problems, entirely caused by centralized control, are worse than the problem the "alert management" intended to solve in the first place.

It's what makes his oft-use example so excellent. Here you had, presumably, a small group of highly-educated and, presumably, reasonably intelligent folks who couldn't even manage an economy with 150 homogenous players. And yet, we expect much better results when we introduce billions of players and millions of additional variables.
Goalpost-moving? You mean in my OP where I asked whether it benefits the average user? Where I said that the majority of performance issues remain in the DOM?

I moved no goalpost. I am saying exactly what I always said. What the GP said that they are doing is almost certainly an ill-conceived project because JavaScript -- without a major change like asm.js -- simply cannot offer competitive performance as a facet of the language. Which is why we don't build a renderer in JavaScript, but instead layer it over WebGL, for instance.

Only if you use their inbox-like thing, which will still not tell you deliverable rate, it just ensures the recipient can see a list of all attempts.

The actual push notification itself is entirely untrackable unless the recipient actually taps on it, or it is received while your app is running. IIRC you can read out the application's badge number, but that only shows you what the most-recently-received notification was (if it set a badge value), it implies nothing about any intermediate ones. There is no way to list the notifications, nor count them. You can do this with local ones you generated yourself, but not ones pushed to the device.

While someone is actively in your app, you do get a method called that gives you the notification as it arrives - which is handy, because the system entirely mutes it (doesn't go into the notification center, doesn't appear at the top of the screen). You can do that to do a negative tracking system ("they didn't receive this, don't count it in the stats"), or to show it yourself.
> There's no way to insure against that loss

Sure there is. Someone can sell insurance, and you can choose to pay for it.

Perhaps not, but I wouldn't call the FDIC's insurance "100%" either. I doubt it would take very many simultaneous bank runs for problems to arise, even with the FDIC.

> otherwise half of all circulating BTC would be in an insurer's accounts

I'm not sure why half of all BTC would need to be in insurers' accounts, and I'm not sure why that would be an inherent problem even if it were the case.

Is Bitcoin the New Digital Currency?
Canary Islands save 70 per cent by switching to open source virtualisation
This is in turn nice for people using .io domains, the weight of Github's many blogs and official project pages will lend trust to the TLD.
The flaw in the argument is that BitCoin is not (currently) a unit of account (we don't price contracts or goods or services in BTC), and is (nearly) infinitely divisible.

So even if 90% (or 99%) of all BTC is being hoarded, the other 10% (or 1%) can be divided up for use in transactions. That much speculations will cause wild gyrations in value and massive short term volatility, but the people using BTC to transact JUST DON'T CARE.

I really don't care if I'm buying my $1000 flat screen with 1 BTC or 0.0001 BTC. Neither does the merchant. I bought the BTC, sent it to the merchant, and the merchant sold it so quickly that the value didn't change much, and we are happy.

So that's the short term. In the long run, the volatility might decrease as the total market capitalization increases to 10x or 1000x of its current value.

Then we can start to think about using it as a unit of account. If we do, we may enter a deflationary spiral, but by then BTC will already be used in an enormous swath of the economy.

So I interpret Krugman's argument not so much that BTC CAN'T take over the world, but that it SHOULDN'T take over the world. (I'm not sure if I agree. Many economists have been arguing over this point for decades, and I'm not smart enough to sort it all out.)
In other words, when people run out of physical goods to trade, they will start trading IOUs, at which point inflation has occurred within your economy whether you intended it to or not.
I think it would also be interesting if one could simply subscribe to push notifications without even having to download an app.
> Being able to subdivide and increase in value are not attributes unique to bitcoins.

I didn't claim that.

> Oh, and the article DOES address this exact point.

No, they always assume the value of a coin remains constant when discussing subdivision.
Facebook Home: Is That a Feature or a Threat?
"If you have a $10 bill and I replace it with ten $1 bills, do you feel richer?"

Yes, If I split my 10 into 10 ones and if 9 can pay today for something that cost 10 yesterday, I feel richer.

This causes folks to save and horde like in Japan. Because its deflationary.

It's more difficult to control the masses via monetary policy if things are deflationary... That's why governments try to maintain slight inflation. Comfortable folks don't produce for the government.
Not sure yet how I feel about the .io bandwagon that seems to be going around; I think I mainly don't like taking a TLD that is specifically designated for a country and attempting to attach a different meaning to it. I just don't know if my pedantry is justified... Yes, I know it's been happening forever, but that doesn't make it right.

I do like the delineation between official Github content and user-content, but there definitely other ways to go about the problem without buying into the latest TLD fad.

I'll give you another example. That was one game I have in mind that involved simply pixels. 100x100 grid is 10K objects; 400x300 grid is 120K objects. 40fps x 120K is about 5M objects/second. Each object involves however so much processing. Doubling to 800x600 gives 20M objects/second. It adds up fast.
Great all around, I hate all the links that show up here as from github.com when they're actually from username.github.com, or even gist.github.com. Though I guess this doesn't say anything about gists, maybe they should move those to their own domain too. Although I really think HN should show the first level subdomain of a domain if one exists.
The key point is that bitcoin is not actually a currency (like the dollar or euro), it is a commodity (like gold or silver). Thus it will be subject to speculative bubbles and unpredictable swings in value, and the typical holder will not be able to do much about that.

Central banks and fiat currency remove the danger of speculative bubbles...or at least, they centralize the danger to a single, publicly controlled entity.
It would be interesting to see the results for Grails 2.2 (which uses Groovy 2 and Invoke Dynamic)

One of the nice things about Grails is that you can easily drop down to the Spring and/or JVM level when needed for performance.

> if you want to get people off the streets, you need to make a credible effort to get them off the streets.

I think the goal should be to get people living healthy, satisfying lives, not a simple 'get them off the street'.

Some homeless in SF choose to be homeless, and they're explicit about that fact (there was an article about the kids in the park here on HN a few weeks back, I can't find it). The goal of getting homeless off the streets does nothing for that population.

So if the goal is to increase the happiness of the well-off folks in a city, then by all means, get people off the streets by renting them apartments. But if the goal is to help the homeless find meaning in their lives by participating in society, that's a whole different ballgame that nobody has solved yet.
