If you're developing software that needs to be installed, then please read the parent post. Too many software install guides are pointers (such as install x, or install y), but fail to provide step-by-step instructions. And this results in people finding your install "funky", or whatever. But not easy, painless, simple...

For all of its flaws, documentation is an area that Microsoft does very well. IMO, many companies and projects would be better served by step-by-step guides.

The following are the commands I used to setup Ghost on Ubuntu Linux 13.04 x64. The only assumption below is that you have git setup already.

# switch to root so you don't have to sudo repeatedly

sudo -i

cd; mkdir packages; cd packages; wget http://nodejs.org/dist/v0.10.20/node-v0.10.20-linux-x64.tar.... gzip -dc node-v0.10.20-linux-x64.tar.gz | tar xf -

echo 'PATH=~/packages/node-v0.10.20-linux-x64/bin/:$PATH' >> ~/.profile; source ~/.profile

which node

# Install ruby and gems

apt-get install ruby

gem install sass; gem install bourbon

# Install Python

apt-get install python python-virtualenv

easy_install Pygments

# Clone Ghost (assumption: you already have git installed/setup)

git clone git@github.com:TryGhost/Ghost.git

cd Ghost

git submodule update --init

npm install -g grunt-cli

npm install

grunt init

npm start

Ugh, I wish New Scientist would just go away. No link to the original study, gross exaggeration of the study's findings and scope in the headline. And a mention that one study doesn't overturn the entire existing body of research would have been nice.
Ah, socratic method. I do sometimes try that, although sometimes there are people who don't even respond.. which means perhaps I'm expecting too much change too quickly with their character :) it may also be that I need more confidence. Or that sometimes I need to drill down to what they really don't know. I have other friends who ask me questions I'm well aware of, so I discount their questioning. But soetimes if I listen they have a new perspective. So the ability of your friend to be open matters 8)

I'd like to say that it would be around the current price, being stable for a long time through block generation would cause a lot of trust.

Though in being money (finite) rather than a fiat currency I think that in reality it may either be commandeered or destroyed by the current financial system.
Actually, he hasn’t deleted the 50 BC. They are still there but they are trapped. He only deleted the only copy of the key to transfer them, so those BC will be trapped there “forever”.

Actually it’s possible to brute-force search for the key and make the BC free, and transfer them. But with the same method it’s possible to steal BC. The brute-force method is just too slow, and would require a few thousands or perhaps millions of years. (I don’t remember the exact estimation.)

With the help of the Moor’s law and some advance breaking the cryptographic security measures, this can happen sooner, but this would be a problem for every BC user.

It's a lot like playing poker. If you look at the results of a hand it's very likely you'll get the wrong idea of how you were supposed to play it. Even when you make the right play you still expect to lose some amount of time.

Or when you're buying stock, you might expect the stock to go up by 100 points 10% of the time and down by 3 points 90% of the time. Just because the stock lost 3 points doesn't mean you were wrong to buy it (you expect to make 7.3 points in the long run).

> I hate to be nitpicky, but the part about always looking for a better job is horrible advice in terms of marketing yourself. It's pretty well-known that bouncing around from job to job turns pretty much every employer off.

Yea I was thinking about that... an option that is so plainly impossible that it doesn't need to be considered (over 1/3 of all BTC does it). I imagine $1.5 million is just on the edge of plausibility for some adventurous, wealthy founders here.
If environmental damage actually cost money in that way, a lot of problems would be solved.

The problem is that there are a ton of externalities. Farmers aren't paying the cost for the ecosystems they destroy or the waterways they pollute or the monocultures they develop or the greenhouse gases they emit. They can trivially do more than $4 in environmental damage for your $4 purchase.
I've always wondered why more people don't live in Oakland or Berkeley, which are both a relatively short commute to downtown SF. The housing prices are significantly cheaper, and especially in Berkeley, there seems to be a strong tech community.

Without going into all of my guesses as to why this hasn't happened in droves, I think one of the larger reasons is the access to cheap transportation back to those areas at night. BART stops too early, so for the younger crowd that likes to stay out, it's too expensive to constantly take a $40-60 ride out of SF. Without the advent of additionally public transportation, would it be economically viable to provide a paid shuttle service to and from SF / Berkeley / Oakland?
The leak happened because there were FoI requests being contested by parliament.

https://en.wikipedia.org/wiki/United_Kingdom_Parliamentary_e...

> A February 2008 Freedom of Information Act request for the release of details of MPs' expenses claims was allowed by an Information Tribunal. The House of Commons Authorities challenged the decision on the grounds that it was "unlawfully intrusive".[6] In May 2008, the High Court (England and Wales) ruled in favour of releasing the details of MPs' expenses claims.[7][8] In April 2009 the House of Commons authorities announced that publication of expenses, with certain information deemed "sensitive" removed,[9] would be made in July 2009.[10]

> However before this could take place, a full uncensored copy of the expenses records and documentation was leaked to the Daily Telegraph, which began publishing details in daily instalments from 8 May 2009.

>To conclude, it is the element of deceit.

And that's what makes this tricky, because stock market situations are so unlike ordinary life. Is there deceit?

The OP has the option of returning the papers as soon as possible, and informing the people he returns them to about his stock market plans. He could in fact tell everyone he meets about his stock market plans and still be capable of a tidy profit.

There's something uncomfortable about the situation, but it's really hard to pin down what it is, and I don't think there's any dishonesty involved.
I'll assume you know about oats and there's unprocessed, slow cook, quick cook, instant... The problem with quinoa is its all marketed as quinoa although by analogy, you can buy completely unprocessed which takes forever, somewhat processed which still needs some rinsing, and super processed safe to use in prepared box mixes. You have to read the fine print. If you make the mistake of treating raw unprocessed from a farmers market as if it were perfectly dehulled ready to use box mix grade, it'll taste so awful and bitter that you'll spit it out, and probably swear off the product.

Maybe a worse analogy is its like getting a live chicken, vs a shrink wrap boneless skinless tray at the supermarket, vs getting mcnuggets at the drive thru, its all marketed as "chicken" but it matters a lot what kind you buy.

There's probably a startup lesson in here. Life would be a lot more consistent if the quinoa guys never sold processed, for example. It might be less convenient but at least it would be consistent, and inconsistency means confused unhappy users. Consistently PITA sells better than inconsistently PITA.
The study you cite is a better study too in that it's randomized controlled prospective study, whereas the one linked here seems to be an observational one. Observational ones are the ones where everyone says correlation doesn't imply causation.

Can I admit here that I hate "the Sunday test"? I wouldn't ever want to use that on somebody, nor would I want it applied to me.
I'll give you a serious response, as explained to me in a recent interview I had for a research scientist position: branding. Some researchers in industry are given fairly wide latitude in the topics that they are allowed to study. In these cases, the company usually gets little direct benefit from the output of the "pet" research idea. For such researchers, their indirect value is the publications and resulting press that hopefully increases the brand of the corporation in a more general sense.

I think it's a fair trade off to have to make if you're considering industrial research. I'd also note that academia isn't much different -- most of those releases also start with something like "MIT researchers..."
Until recently I don't think any major hash table implementation (e.g. not Java, STL, Python, Ruby, etc) used a cryptographically secure hashing algorithm. They're just too slow. Slow enough that you might as well use a tree-based data structure, which doesn't suffer from hash-collision based attacks.

This is changing a bit now when SipHash is available. Unfortunately SipHash still is a bit too slow and forces an uncomfortable trade-off.
In my opinion, the biggest problem with an "ad-hoc" framework, or custom-built framework, is that there is definitely going to be less documentation for the next person on how to use that framework.

Integer() or Float() let you do cool things like this:

Which will let you know if some input passed can be safely converted to an integer.
Please don't blame R for the ggplot syntax -- it is bizarre on its own. Also ggplot requires very specific form of input, and thus many scripts must be heavily polluted with a nontrivial preprocessing routines.
Here is an article[1] about how the senators and politicians in Tennessee try to avert installing a German-style Betriebsrat (workers' representation) in their Chattanooga plant. The plan is to have it with UAW.

I did some evaluation a while ago about bundling a Javascript engine with mobile apps on iOS and concluded JSC was way easier to compile and integrate. This is in fact what e.g. Appcelerator Titanium does currently.
However, this bundling results in huge binaries, which is not very nice for mobile platforms.

The thing that got me into hacking the prototype was the release of JSC as a public system framework on iOS7, eliminating the need to separately bundle JSC.
So its not really a platform preference, I'm just trying to work with what's currently there...

While mathematically correct, this does not seem to be how people use with that phrase. "X is probably going to happen" implies there is some evidence in favor of X, while "X is probably not going to happen" implies evidence against. Now, in regular speech, people do not feel compelled to force themselves to choose one or the other, but are just as likely to say "I have no idea", implying no evidence in either direction.

From an Information Theory point of view, 50% probability means zero information, and 25%/75% probabilities mean one bit of information against/in-favor-of the event. This sounds roughly consistent with the results of the poll, with people assigning higher probabilities implying higher information density of the evidence.
I would be interested to see what the blood levels of EPA/DHA were in the patients studied, the article isn't really helpful in that respect and it may be important.
Drone delivery methods attack the aspect of delivery with the lowest value-added, and there isn't much evidence that it can do it more efficiently than current methods that get aggregated to a truck and then disaggregated on a route.

When you pay for a person to deliver something within the same city (the relevant range for drone delivery methods), well over 80% of that value is attributed to a human being that is capable of doing the following things: Finding obscure building entrances, knocking on doors, collecting signatures, backing up vehicles around obscured corners into loading docks without hitting trash cans and sleeping homeless people, identifying obscured address signs, pressing the correct buttongs on elevators, avoiding malicious dogs, and placing packages in places that are obvious to the recipient and non-obvious to thieves.

To be sure, this also applies to driverless-vehicle delivery as well, although the value-added aspect that is provided by humans is lower because the relevant range of the vehicles is higher.
> And of course economics==financial economics.

Yes, because of the huge influence of the leading economists have on the world today.

Economics, in general, is plagued by poor research, poor results, and bad logic.

They help shape fiscal, monetary and economic policy, yet make horrible risk assessments, horrible predictions and believe their own bullshit.

>Economics deals with an ever changing environment.

Economics is way more complicated than people will admit.
How can you model 7 billion people interacting? It's impossible.

Yet, they give these charlatans huge salaries, awards, real power in government and don't hold them accountable.

The leading economists (with a couple exceptions) still don't admit they don't know anything and won't adjust their thinking.

I just dropped by to say that Stanford Ovshinksy is not unknown ... just relatively lesser known. I knew about him as far back as 1997 thanks to a documentary about him and his work. I recall one of the catch-phrases he used to describe his work with amorphous crystals - "Tyranny of the crystal".
Er, Natural disasters, as caused by climate change, are increasingly within the sphere of human control. War is also very much a result of our own behavior. I have trouble with the argument that 'ignoring' these things has a positive outcome.
If any SF residents agree with the sentiment of this article, I'd recommend voting in the upcoming election. Props B & C will allow a project with new housing, retail, and open space to be built downtown. I support the project not because it's perfectly designed, but because it would set a terrible precedent for future development in the city if opponents successfully use the referendum process to block it. Ironically, many of the same people opposed to the project are the ones who are complaining the most about rising rents. Even though the project certainly isn't low- or middle-income housing, it will relieve some of the demand that would otherwise be placed on housing for lower incomes.

I would have to disagree. I think for personal finances and experience you will always get a better deal by moving to another job every 1-3 years. 3 years might be the maximum if you're just doing the regular salary type of job. I have no experience with the start-up scene and I'm talking just about regular corporate jobs that offer no equity or valuable stock options.
I'm curious if the development of ASICs generally increases or decreases the security of the network.

It seems to me that the resilience of the network to attack doesn't depend on the total computing power of the network, but on the dollar cost of the total computing power of the network.

If ASIC deployment increases the computing power of the network 10x, but the availability of ASICs reduces the cost per unit of computing power by 11x, I would think it makes the network as a whole less secure.

In other words, the existence of ASICs increases the computing power of the network, but the existence of ASICs also makes it cheaper for an adversary to buy boatloads of targeted computing power to attack the network.

The whole western side of the city could really use some development. Nothing there is particularly nice as it is now. A lot of units don't even have laundry machines in the buildings, so people end up spending thousands per month on rent while still using laundromats. The location, however, is amazing given the proximity to the parks and beaches, and there are solid commercial arteries. There's not much character there, and almost everything is relatively new, built within the past century.

Regarding people moving to Oakland, there has been some people here talking about how bad the crime was there. Then again to me, San Francisco is a really dirty city with a ton of homeless people.

There's also a given that 6hrs after sunset there isn't a need for as much power... most of the population is asleep, lights off, TVs off, etc. There are other traditional power plants (Hydro and Nuclear) in AZ that provide overflow service for off hours. It actually takes a combination of plants to offer the best load distribution.

In parts of AZ there are serious brown outs and rolling blackouts in the summers as A/C kicks in everywhere, which is probably the biggest draw.
