That is the trick, they are disposable (in theory). You use them to mine more than their net cost in bitcoins and then you throw them away, investing X$ in the miner getting out Y$ (where Y > X) $ in bitcoin. Return being (Y/X)/period

I doubt the ASICs can be retargeted. Although the cabinets and power supplies etc could (in theory) so you could turn around and re-populate it with SHA1 ASICs or something and start passwords or something with the boxes (would need new boards and programming though)

The author is measuring largest cluster-size vs threads/button.

In any software, everything is going to be connected, otherwise there's unreachable code. So the largest cluster is always 100%, so I don't get why his argument about the sudden phase transition is relevant to software?
Just FYI: This is just a wrapper around matplotlib, so it's not intended to replace it at all. Thus the non-pixel-to-pixel relationship with ggplot.

Isn't this the same thing as "Meat does not make you muscular?"

their introduction stated that if you slipped, you would have to pay to get back on schedule, and not on your terms either.

you would have to pony up a credit card number on the grounds that they could charge you if you slipped again. Basically if anything happened, $5, $10, $30

Oh no, my father was killed in south Africa, gotta go! $5, $10, $30, $90, $270, $810, $2430, Oh you were busy? Oh sorry.

I think I first discovered quinoa in a cooking program 10 or so years ago. Some of the comments here seem to assume people consume it just because it's trendy in some way.
For what it's worth, I like it simply because I like the taste, its slight crunch, and just as something different occasionally.
Of course an application like Bitcoin needs a cryptographic hash. But the parent comment was concerned that a single-digit number of collisions showed up in a couple hundred thousand test cases of a 32-bit hash. A similar count of collisions has a good chance of showing up with a 32-bit cryptographic hash, too. It's the cryptographic properties in concert with the size of the range that make the function secure for its intended use.
For the nukes there are a few so called SMR (small modular reactors) being worked on, and some of the are in process of licensing with NRC.
The main selling pint is that these units with a capacity of about 200MWe can be deployed under 1bil dollars when compared to 15bil dollars for a large plant (>1000MWe). Most of these small plants can operate in a load follow mode, similar to gas plants. Also their footprint is similar to that of a gas plant rather than to that of a large nuke.

I have 1 BTC I really love the idea of using it and if a had a easy and consistent way of getting it i would use it for most of my online transactions.

As it stands now it's incredibly hard to find someone selling BTC unless you're willing to mail a copy of your ID over the internet something i would never do.
I stand corrected. If this is the case, then I expect the situation will sort itself out in time.
The main problem is that they have system library dependencies that pip doesn't handle.
That's a very dismissive attitude to take. If you wanted to know if I was a troll, you could've read any of those 9 comments and found out yourself.

Just curious for the reasons for not liking Python.
And Ember shares a core developer with Rails. That said, they are different things, but Angular seems to be taking a jQuery-esque position against Ember's Prototype, IMHO.
When you know one thing really, really well and it's a niche, it can seem be in your best interest to setup camp or form a tribe, or whatever...maybe not the case here but I see it a lot, DBAs specifically come to mind.
There are already 'peaker plants' which are generally gas fired turbines which can be activated to supply power on demand, but they are more expensive to operate as start/stop systems (startup consumes a lot of energy in its own right).

So generally 'peakers' aren't good fits for the other side of the energy generation equation.

Which in this case would make things a little more difficult cause Ghost uses SQLite and Dokku can't deploy apps which use it because of default Node.js Heroku buildpack which prohibits SQLite usage. You can patch a buildpack though.

> ethical questions of eating animals as well

Grain and legume farming kills massive numbers of amphibians, birds, and rodents, with huge knock on ecological consequences. When you slaughter a pastured cow or sheep it's one life. During their lives the hooved animals serve a vital role in grassland ecology. The 1930s American dustbowl desertification happened in substantial part because of the preceding elimination of bison and steer.

> a barn full of chickens in cages

If chickens are caged in barns they're eating mostly grain. Historically normal chickens ran around outside and ate mostly bugs, in season.
This seems to be very of date? My understanding was that when SipHash arrived it knocked out all of these? (Please correct me if I'm wrong.)

This may be an interesting weakness with the StackOverflow system; if there's an answer that used to be very good, it may take a lot to knock it out of the first position when reality changes.
I used run a lot of training courses (2 - 5 days, perhaps 2-3 times a month) as well as conference and exhibition speaking.

Once when my voice was a bit worse for wear, I asked a pharmacist for suggestions and he pointed out a commercial product, but said that since the main active ingredient was liquorice extract, I might as well just buy a bag of the stuff at the local store as it would be a fraction of the price.

Fortunately, I like liquorice and I have to say it's always worked for me - although you'll need to consider those nearby if you're walking the room and mitigate the liquorice with perhaps a sugar-free mint.

> 5. Buy in 1973 and sell in 1992, realizing 2% annualized over 19 years. Again, you'd have to suffer losing over half your capital before you eventually came out on top.

You seem to be ignoring dividends.

The S&P 500 gave a total return of 11% nominal and 4.5% real from the high point in 1973 to the low point in 1992. (Note: I only have monthly figures for the 1970s.)

SPXTR, Jan 31, 1973: 60.27
CPI-U, Jan 1973: 42.6

SPXTR, April 8, 1992: 457.16
CPI-U, April 1992: 139.5

Total nominal return: 457.16 / 60.27 = 7.59
Annual nominal return: 7.59 ^ (1/19) = 1.11

Total real return: 457.16 / 139.5 / 60.27 * 42.6 = 2.32
Annual real return = 2.32 ^ (1/19) = 1.045

Historically, dividends have accounted for over half the return, and thus you cannot simply ignore them. This is why I use the S&P 500 Total Return Index (SPXTR) to calculate returns, not the S&P 500 Index (SPX).

Note: Taxes not included in the calculation. Alternative investments, such as bonds and money market funds, would've been taxed as well. You could've gotten tax-deferred compounding starting in 1975, when the Traditional IRA was created.

Your understanding is incorrect.

The mining activity produces two rewards for miners: a 25 bitcoin bonus for being the first one to find a hash for a block, and a small percentage of each transaction included in the block. The bonus will be ramped down over time and eventually go to zero, but the percentage will always be there.
How are you liking it? It's very handy for launching apps, for sure, but I'm wondering how you can configure services (e.g. how do I set up redis persistence or nginx directives or postgres backups?).
It's actually really efficient, so much so that I think an interesting question is scaling that technology down rather than making a new technology to replace it.

There are a lot of interesting technology advances related to better manufacturing processes & material science for turbine blades. The closer we can get to the "ideal" shape, the higher performance the turbine. Single crystal turbine blades are an incredible feat.

Just How Much Editing Is Too Much Editing?
This is similar to something I've been wanting to do for quite some time. In contrast to your approach (binding JavaScriptCore at the Objective-C level) I want to start with the JavaScriptCore's command-line interpreter. It's currently a barebones interpreter. I would start by adding some missing primitives to the interpreter getting it closer to the V8 developer console (d8). Then work from there.

Good work though. It's nice to see that I'm not the only person that has thought about a Node-like system built on JSC rather than V8. I wonder if you looked at the source for both V8 and JSC, and then concluded JSC would be much nicer to work with? That's what I did initially.

I wish I had time to pitch in right now...

They're generally not usable for anything SHA256 related. The input they take is a string, and a range of nonces to attempt. The only data they return is a positive if a particular nonce gives a low enough value. There's nothing useful there except for hashcat-like operations.

>Human beings are designed to operate in 90-minute cycles. At night, we move through the five stages of sleep in that time — the Basic Rest Activity Cycle. During the day, we are guided by our ultradian rhythms, and we move from high physiological alertness toward physiological fatigue in 90-minute intervals.

I was in the comments here the other day defending the use of words like "design" and "purpose" to describe evolution. But even for me, this sets off my bullshit detector.

I would accept the sleep thing, though a precise 90 minutes is a stretch: "In humans, the average length of the first sleep cycle is approximately 90 minutes and 100 to 120 minutes from the second to the fourth cycle, which is usually the last one." http://en.wikipedia.org/wiki/Sleep#Physiology

But does anyone have a citation for that kind of cycle during the day?

In my opinion it is. You should start writing functional tests that test the application from the users perspective. Capybara/Selenium/Cucumber for example are a nice combination for this.

Unit tests are great for catching specific small issues, but you always want to make sure that your users can go through the most important steps in your application. These need to be thoroughly tested.
They could also be used for other blockchain based technologies such as bitmessage, or future voting systems. (I think, correct me if I'm wrong)

Steam turbines are the most efficient way of turning heat into mechanical and electrical energy. You can get a slight efficiency boost at tremendous cost by changing the working fluid to something lighter, but nobody bothers with that.

There's some interesting research in using fuel cells to extract energy from natural gas and oil, which potentially could be more efficient. This doesn't work for coal, though.
There is, however, a significant correlation between meat eating (or more specifically protein consumption) and muscularity. If you corrected for exercise in the right way you would still see this correlation (a naive approach would remove all effects of exercise and you would lose the correlation).

So if this study is taken at face value (and well, no, don't do that) there is no correlation even before correcting for other factors.

Couldn't disagree more strongly for economic reasons.

Lets say I pay $4 for a pound of bratwurst. He cannot do more than $4 of environmental damage and still stay in business. Even if brats magically fell from the sky for free, he simply can't do worse than stack up $4 worth of lead and old car tires and set them on fire or whatever other environmental degradation you can imagine.

The good organic farmers market meat costs more than $4/lb but less than $10 so the argument still holds. In fact I'm about to take delivery of a quarter-cow from a local organic farmer, got my high efficiency freezer all defrosted and emptied and ready to fill with delicious organic local grass fed beef.

On the other hand, the guy who I just handed a $10 to for a pound of quinoa can stack of $10 worth of old car tires and set them on fire and dump $10 of antifreeze into the river or WTF. He can afford to "ruin the environment" to the tune of $9.99 and still stay in business, unlike the brat guy above who would go almost instantly out of business if he spent $9 trashing the environment for every $4 incoming.

This is before I even get started on the supply side, where for the sake of argument lets say I have to kill one baby seals per $1 take home pay. That means to earn the $10 for quinoa regardless of how "pure" his quinoa growing operation is, ten baby seals died, whereas to earn the $4 for brats, regardless of how "pure" his pig sty is, a mere four baby seals had to die. I would argue that most people in the real world work at pretty ugly companies, ecologically speaking, so most of the enviro damage comes from earning the money rather than how its spent. Another example is I burn about a gallon of gas per day that I drive to work, so even if I do the ultimate green thing and finance planting a rainforest or something, I've still ecologically destroyed a gallon of gas before I even crack open my wallet.

There are some interesting petroleum arguments also, in that a pound of "meat" from the organic farmer five miles away at the farmers market burned a heck of a lot less diesel / bunker fuel than a pound of quinoa from another hemisphere. Although a small timer grew and sold a little native quinoa at the market which I bought, reality is that the vast majority of it is imported from another hemisphere at substantial cost.

I can buy locally grown organic beef, pork, and chicken. Most people can't buy locally grown quinoa. Some people can, and American's are literally starving them out of the local quinoa market, which is too bad.

Don't get me wrong, I am a hard core environmentalist at heart for example I think people who dump industrial waste into rivers I hike by should be capital punished by being forced to drink what they dumped till they croak, its only fair since the poor bastards living downstream are already literally drinking it... But feel good irrational non-analyzed environmentalism does more bad for the earth than good, and it turns out the reality is that everyone's better off if I eat a quarter pound steak rather than a quarter pound of quinoa, under existing conditions.

Taleb only clearly pointed out that if you use pricing formulae based on the assumption of a time-inavariant Gaussian distribution of returns, all small gains you accumulate in the good states will be wiped out and more by losses you will suffer in the bad states. But this is because you have underestimated the downside risk.

If you used a havy-tailed distribution (e.g. something from the stable family, which was suggested by Mandelbrot (1963) and Fama (1965)) and/or allowed for time-variability of moments and/or accounted for systemic risk you would see different prices of assets that better reflect that downside risk.
