Thanks for sharing that.

However, that paper only looked at the correlation between the S&P500 and long-term treasuries. A well diversified portfolio should have a mix of bonds including commercial bonds.

The disclaimer in the paper points this out:
Bonds are represented by long treasuries (Ibbston) which should not be interpreted as a full sample representative of the bond market. Different asset class proxies will have different results.

The data that I've seen on stock-bond correlation shows a pretty consistent negative correlation over the 1927-2010 time period. It's not perfect, I admit, but it serves you well when you're trying to minimize risk.
Ah, you've seen that comic come by on reddit too, eh?

An M-16 costs far more than $1,000, and is not available for purchase by the average citizen. Between the 1934 National Firearms Act, which prohibits the sale of fully automatic weapons to those who do not submit themselves to an extended (months' long) background check and pay an additional $200 tax stamp, and the 1986 National Firearms Act, which make all fully automatic firearms manufactured post-1986 non-transferrable to citizens means that the fair market value of an M16 is something closer to $15,000-$20,000, and that's for a used model that's at least 25 years old.

If those acts were repealed, I agree that the suggested MSRP for an M16 would be ~$1,000-$2,000.
I'm not too sure either. In JS, block scoping does not exist. There are only function scopes, so the var declaration gets hoisted out of the if block (but the assignment occurs in the if block - so the assignment doesn't happen).
This[1] is a pretty good resource on ES.

No, sorry. Which companies I visit is - for obvious reasons - subject to NDAs. And there is more to the .de startup scene than the Samwer brothers, a lot more, actually.

What you could do is scour the websites of the various EU venture capital companies for press releases indicating investment into companies in Berlin and surroundings. If you make a nice survey and posted it here that would be a great resource to have.

Maybe this could serve as a starting point:

# By Michael Lewis, published in the NYT today
The idea that an HFT can see you attempt to buy stock before it goes to the market is not true and would be against the law if it happened.
If I understand this article correctly the problem isn't the missing permission type provided by dropbox but the location of the settings file which was placed on the root level of your dropbox (for historic reasons). There's currently no way to access /dropbox/mythings/morethings/onepasswordfolder and /.onepasswordsettingsfile so they need to get access to / to keep the historic file at root level working.

Disclaimer: I don't know anything about Dropbox permissions or their API, I'm just judging this by reading the article.

Edit: And now that I re-read the parent comment it seems that maybe I misunderstood your comment and it's already possible to have different permissions at different locations.
"We could have been more sceptical of NSA's intentions," RSA Chief Technologist Sam Curry told Reuters. "We trusted them because they are charged with security for the U.S. government and U.S. critical infrastructure."

PS: "We also would like to express that we believe the entire World to be a bunch of idiots."
Every kid (ideally) learns the difference between "real" and "not real", and, more subtly, the difference between "valid example" and "don't trust this, it lies" (e.g., most television, which is exaggerated for effect).

I've seen plenty of assertions that porn is a special case for which the general lesson doesn't suffice, but never yet run across a supporting argument which didn't reduce to "well, because genitals are involved." Which, I mean, I understand why that would seem to an ape like a sensible thing to say, if an ape could talk, which we can. But I'm curious to know whether anyone has a genuinely novel argument to make in defense of the proposition.
I suggest changing the tagline. It's not "a blogging platform for introverts". Such a thing is impossible. Calling it that demonstrates a distinct lack of understanding about introversion and what it means to be introverted.

Introverted people as a group are as diverse as any other group of people. The only thing that sets introverted people apart from extraverted people is what they do following social interactions: introverted people look inwards to recharge while extraverts look outwards. In short, if spending time in a group makes you feel tired and you seek time on your own to recharge, that means you're introverted. If spending time in a group makes you feel dynamic and full of energy, that means you're extraverted. Everyone is somewhere on a spectrum between those two states.

Being an introvert in a society that values social interaction so highly is difficult - take a startup accelerator with social events practically every night as an example and it's obvious why. Being the person who goes home early and gets labelled 'shy' or 'antisocial' puts you at a great disadvantage when really you're just genetically predisposed to feeling better spending time on your own (or in smaller groups).

There is no reason whatsoever why an introverted person wouldn't happily use Wordpress/Tumblr/Jekyll/whatever for their blog. What you are catering for (eg "people who want to blog anonymously") is something else entirely.

I think what we need for people who don't want insurance is some way to "opt out" of the health care insurance system - maybe a special card you carry that indicates to the emergency room or hospital (where maybe you have been admitted, unconscious and close to death from a car accident) that indicates any medical assistance provided will be 100% your responsibility - i.e. bill me or whatever.

Why do I need to carry a card? What purpose does the card hold other than to tell the medical provider to treat me differently (as if I could either not pay (unfair to me, how do they know my assets) or could pay for better treatment (unfair to everyone else, why are some suffering through mere insurance while I have the good stuff that daddy greenbacks bring))? If you are differentiating for those without insurance, you surely must do the same for those with the comically legal 60/40 plans that have no practical out of pocket cap. 40% of a 100k bill is practically the same as being uninsured when looking at the effect of causing a bankruptcy to most of the country.

The only problem is that someone could then just claim bankruptcy and push the burden back onto the insured - so we'd need to make it so bankruptcy could not remove that outstanding debt.

Would you prevent people who signed up for 60/40 co-insurance from Aetna or Blue Cross to file for bankruptcy when they cannot afford to pay their 40%? If not, why? They choose* to not pay for better plans that limit their out of pocket liability.

Making bankruptcy harder isn't the right solution. Complete nationalization is only solution that doesn't leave uninsured and underinsured individuals who need to take a bankruptcy after an illness or accident. If that is truly the goal, then that is what should be worked at.
>not paying for birth control coverage when there is absolutely zero chance of pregnancy

The argument here is....

It is in our best interest as a society as a whole to have a society that controls its fertility. We have less children born that aren't wanted, less teen pregnancy. Les children in hardship. That's a plus for society.

It is also beneficial to society to have children who are born healthy. That's why we are all required to pay for maternity care.

It is also beneficial to society to have a well educated populace, that's why we are all required to pay for primary education (through property taxes) even if we have no children, and can't have children.

Educating the women in society and giving them access to birth control is one of the best ways to pull a society out of poverty.
But, as with the old adage "RAID is not backup", don't forget that ZFS is not a backup either.

ZFS has bugs like any other codebase, and metadata corruption will make your whole pool unrecoverable. RAID-Z and block checksums won't save you from that.

I speak from personal experience with ZFS. Backups are important, no matter what filesystem you use.
Does the word "NSA" still have a 60 percent upvote penalty here? It seems to be moving pretty slowly up. I understand using that sort of penalties if during a period of time the site gets flooded with those stories, but I don't think keeping the penalty forever is such a good idea, or at least not such a big one. Maybe make it "decay" over a period of time.
> hairlessness seems to have come from porn

I've seen a lot of just-so stories on this subject. Has anyone got any evidence to show?
Yeah, the former has no Constitutional or prior to the 20th Century, US historical basis, the latter has both. And for the Constitutional basis, I'm not referring to the 2nd Amendment, but per Article 1, Section 8:

"The Congress shall have Power...

To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;

To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;
I meant that there are people who never had any physical relationships whatsoever with other people and only know about it through videos. Also, I didn't really mean to pass judgement on porn, but I think we can agree that most of nowadays porn is a very cheap product (both in price and in ideas) from an industry. AFAIK in the 80s it was less so, hence I'd grade them less cheap. I don't see where I implied any causation.

If I may rephrase the question: what are the effect on a growing mind whose only experience about intimate/sexual relationship is alone watching videos.
It pretty much describes the startup ecosystem, so it may indeed cut too close to the bone ^_^
The problem is not the HFT firms buying stock cheaply and reselling it for a profit. As the article points out the problem is investors placing a buy order, and the HFT firms seeing this buy order and snapping up the remaining stocks before the original buy order is fully completed.

This has the negative side effect of essentially making it impossible to buy for the listed price, even when there are supposedly enough shares available for purchase at that price.

As I pointed out in another comment, it's not just buying low and selling high; it's like Walmart interrupting a customer to jack up the prices on a purchase in the middle of that purchse, precisely because that customer is buying that specific item.
Agreed. A tech hub in Europe has a potential pool of talent/investors as high as the US, and doesn't have to compete with it.

Still, I'm very skeptical about ANY city here coming close to SV, mostly because of different mentality/tradition/culture across the ocean.

London in theory has everything going for it (ok, high cost of living, but so SV and NYC), but you don't hear so many success stories coming out of it.

The biggest drawback of Berlin would be the language, in my opinion.
Bitcoin Is Pointless as a Currency, But It Could Change the World Anyway
Yep. Why would anyone "schedule maintenance" on the day of the deadline?
Such quantity? It's like 2 million units. That's roughly equivalent to a mildly popular android phone model.
Regardless of how the IRS was going to do things, you were going to owe significant taxes anyway.

There were only two choices: Tax BTC as property, or Tax BTC as currency. In both cases, you owe somewhere between 15% to 30% of your earnings to the IRS.
[Infographic] February 2014: The Average Facebook Page Performance
Imagine you have inexperienced coders who do this:

function foo() {
bar = function(){}; //define bar
}

function baz() {
bar(); // use bar
}

Note that both foo() and baz() could themselves, be inside another function. Doesn't really matter. Now `bar` is a defined as a a property of the global object.

If you add

if (false) {
var bar;
}

in baz(), most developers, as I had noticed, will ignore it - afterall, it's a false condition, the code will never enter that branch. But because variables are "hoisted", you have now declared `bar`, it's lexically scoped as a new variable under `baz()`, with the value `undefined`.

So, when `bar()` gets called, it becomes an error, because `undefined` is not a function definition.

...

and yes, dear JavaScript developers, despite all the good efforts of people like Nicholas Zakas, Douglas Crockford, Addy Osmani and the like, bad JavaScript still exists in the wild. And I feel, in greater numbers than ever, and I am not optimistic that the amount of bad JavaScript will be ever reduced. This depresses me. Can't be helped, I guess.
This is really quite silly since the choice between NullPointerExceptions and space leaks is a false one. You can have both in either language.
Actually, wages aren't that low. Taxes are high, specifically the tax brackets mess things a bit! Net salary is a bit over 55% of your gross income when you account for health insurance, pension, taxes AND you don't pay church tax.

Examples:

4000Euro/Month gross, net == ~2395 Euro

5000Euro/Month gross, net == ~2897 Euro

It would be interesting to see how much employees in Berlin cost their employers too.
>I think you are confused about the economics of the situation. Who will pay for retirement benefits? Aging is why we retire. If we never got old, we could work as long as we wanted.

Completely backwards. "We're old and can't work anymore" is the excuse used to publicly justify finally being allowed not to work anymore in a Calvinist-capitalist culture. What we actually want is to minimize the portion of our lifespan spent working for mere wages.

Mind, one reason I've come to support anti-aging and automation advancements is davka that they force our culture to actually confront these issues, that they "heighten the contradictions" as we Marxists say, rather than pretending everything's fine and letting the system get away with its sins.
I think it's either (a) a voting ring, or (b) the changing demographic here. Ignoring (a) (because we can't prove/disprove as we aren't admins/mods), we can discuss (b).

5-7 years ago, this place was "mostly founders and early employees". This would've likely been flagged or, at best, only received a few upvotes. Today, I suspect its 10% "founders and early employees" and 90% "other". This is likely interesting to the "other" demographic - first they've seen it, or it may resonate with them because it's very negative focused and they see themselves in it.
My favorite (C++) : #define private public

Unless I'm mistaken, C++ was (deliberately) specified in such a way that such a redefinition does not affect the behavior of (most) already valid code. Access control doesn't affect overload resolution, for example.

I had to add the (most) qualifier because I bet dynamic_cast<> and other RTTI mechanisms would achieve different runtime results against some classes if private inheritance became public.

Also, I believe that C++ forbids preprocess munging of keywords under penalty of undefined behavior if you include any standard headers, so anything could happen in most modules.

Please don't turn this into a 'best password manager' war.
Analogies with stores/checkers/soda etc. are all flawed because they are based on something that does not exist in the markets, that is a fixed price. When you buy a physical good in a store they have a published price that you can trust to be what you will pay (in western countries that is the norm, not so in many other places.)

Conversely, when talking about equities markets there is no such thing as the stock "price". This is a short hand that is used. In reality, there are groups of people, some willing to buy shares at a variety of prices, and some willing to sell shares at a variety of prices. The job of the exchange is to match these 2 groups when the buy/sell prices intersect or cross. This gets complicated when there is more quantity on 1 side of the buy/sell than the other. Exchanges have rules how this imbalance will get resolved, most of the time it is based on who has been at that price point the longest.
This is ridiculous reasoning...

First off, healthcare.gov is not the only way to get health insurance. Secondly, it's not even the only way to find health insurance using the ACA (you could do this in person, or via telephone).

Finally, a snowstorm is an excellent excuse for not jogging today, but a horrible excuse for never exercising.

The fine is, what, $95? So you could request a fee reduction of $0.26 per day that the system was down this year.
NYC private schools with worse measles vaccination rates than poorest countries
It seems like it isn't against the law.

The thing is, there are multiple markets not just one. So when you place an order to buy 100 shares of IBM, that order gets sent to many places to try to find the best offer to fill you.

If a HFT can see you submit that order to 1 market, and then beat you to the other 4 markets and buy up all the shares before you, that's frontrunning. That would be illegal if your broker did it, but HFT is not your broker, and just has the advantage of being faster than your broker.

What makes you say it's "not true"? What evidence do you have of that?
Another excellent source on this topic is a book I cited in the code comments called "The Algorithmic Beauty of Plants" by Prusinkiewicz and Lindenmayer, available online here: http://algorithmicbotany.org/papers/#abop
The explicit problem is that when Katsuyama changed its strategy to time arrival of trades to all exchanges simultaneously, the effect vanished.

This isn't a supply and demand issue, it's HFT being able to detect an impending large movement and explicitly front-run it, at other exchanges.
I'm surprised this is being cast as Amazon responding to Google's price cuts- the AWS conference was scheduled months in advance so if anything Google heard about the price cuts and announced their own just ahead of the conference as a (successful; apparently) attempt to take the wind out of Amazon's announcement.

Interesting that they dropped by the same amount; either it was a lucky guess, Amazon adjusted their adjustment at the last minute, or AWS has a mole.

Unfortunately, we've set up a lottery where the biggest winners are the ones who write the Great American Framework, and the way people play is by making a new framework/front-end/library/yet-another-thing and fragmenting the ecosystem ever more.

Oh, and then employers will say "we demand two years experience in the thing that came out two years ago -- we need you to hit the ground running!!"

Pretty much everyone in Berlin in the tech industry speaks at least good enough english. There are even some companies that use english exclusively.
Apple's Cyclone Microarchitecture Detailed

I don't believe you're showing you get the point (while making a lot of good tangential points). I seem to remember that government's cost for buying a M4 is something like $600 in quantity, but I forget if that was Colt's price before they lost the contract to FN like they lost the M16 contract (the Army buys the former, the Marines, who are still riflemen, the latter with its much longer barrel necessary to achieve bare minimum performance with normal military ammo).

So presumably in an arming the militia regime, our cost would be lower than the 1-2K you postulate, probably even lower due to massive quantity. With of course subsidies to help the poor ^_^.

(Beginning modified, for bmelton not surprisingly does get the point.)
Katsuyama realized that his orders traveled along fiber
optic lines and hit the closest exchange first, where high
frequency traders would get a glimpse, and then use their
speed advantage to beat him to the other 12 U.S. public
exchanges and 45 private trading venues. HFT algorithms
could then buy the shares Katsuyama wanted, and then sell
them to him at a slightly higher price. [1]

I don't know if this is illegal or not, but I'll eat my hat if anyone gets prosecuted.

I'm bored of hearing about how dull, miserable, offensively expensive and/or painfully trendy places are poised to be the next Silicon Valley.

Now if somewhere like Spain sorted out their bureaucracy and local corruption and made it feasible to set up business somewhere nice, by the sea maybe, somewhere with plenty of nice countryside, in a place where people could actually afford to buy their own homes, and the weather was consistently nice, then I'd be there in a Flash. Who cares if it's not on London or Berlin's doorstep. The actual Silicon Valley is as far away from the US's financial and political capitols as you can get, and used to be a good thing.

Quality of life. That's what will make me sit up and take notice of the next silicon valley wannabe. Until then I'll begrudgingly just go where the work is.
I wonder why its so hard? I once built a modern gcc + glibc in my home directory on an older linux (to be able to run modern programs), and it was mostly "relocatable" or "portable" (what I mean is that you could copy it around and run it from other directories).

Couldn't somebody build a full cross-compiler toolchain as "relocatable" binaries, depending on an older kernel, and then just offer that as a binary download to run on most recent distributions? It's not a typical way to distribute a linux application, but it should work in principle.
> "I claim the opposite of you: that current law exclusively helps the existing, larger companies."

I'm trying to point out that it's driven by whoever is bigger and has deeper pockets. Either for patent fees or for the lawyers who litigate or for the resources to duplicate.

In other words, the 'little guy' is going to get screwed either way so I'm arguing against the specific statement I quoted in my earlier comment (i.e that without patents, someone can invent something and get rich).

I'm not claiming that the current system is ok (far from it), but I do see the benefits of a properly functioning patent system -- (but excluding software patents, they make no sense to me).
