There have been studies proving that the majority of HFT traders are net liquidity 'takers'. The notion that HFT provide liquidity is false but the industry still propagates the myth to main street.

Have a look at a recent paper: http://www.bankofcanada.ca/wp-content/uploads/2012/11/Brogaa...
I'd take the 5 hours of moderate discomfort, because I only get 2-3 weeks of vacation, and I'd rather not burn basically 2-4 days of my vacation on transit. Not only that, but the plane is likely also much cheaper, and I'm not going to spend hundreds of dollars on greater comfort for a few hours.
My guess would be it is, as you indicated, an evolutionary development. When humans are young, we have very little knowledge of how the world works, knowledge which will help our chances of survival later in life. We also have our parents providing what we need to survive (at least during our early childhood). It makes sense that at this time we try to learn as much about the world as possible.

As we grow up, we start to already know more about the world, so their is a diminishing return on more exploration. We also (becuase of our increased knowledge) would move to being the more productive members of the species, so it makes sense for our efforts to go more into survival so our offspring can devote their resources to exploration.
You don't care so much about the density in the abstract, but the size, density, and proximity of the major cities. Several other regions of the U.S. compare favorably to Europe in this regard. E.g. the Great Lakes mega-region has about the same population as France. It's longer (St. Louis to Montreal is about 1,000 miles versus Toulouse to Metz which is about 6,00 miles), but it's also more linear versus France which is squarish. Most importantly, it has 11 metro areas with a population greater than 2 million (leaving out Minneapolis), while France has only 2.

If France can have high speed train from Paris (about the size of Chicago) to Marsaille (about the size of Milwaukee) why can't we have high speed rail between Chicago and Milwaukee (which are much closer together)? Or for that matter Chicago and Detroit, the latter of which is bigger than the 2-4'th largest French metro areas put together?
It would be excellent to have high-speed rail in the southeast, in the Atlanta-Raleigh ("I-85") crescent. This region will eventually be a major urban agglomeration, and improved transit would help its future immensely, as well as the development of the secondary cities along the route. Raleigh, Charlotte, and Atlanta are doing fine; but the Upstate (South Carolina) and Piedmont Triad (North Carolina) could use some help, and being more integrated with the overall region would make a lot of sense.
Just as a sanity check: you are aware that graphics texts and papers don't use the entire Playboy photo, correct? I wonder if we're arguing about the same thing.
Land owners do care, however.

There was talk of a new rail line to the south of Rochester, MN a number of years ago and some landowners were unhappy because the proposed line would split their fields, require new fencing to protect livestock, etc.

Here in Oregon, other landowners have gotten letters from the railways demanding payment for driveways across their lines just so they can get to their property. See http://www.kval.com/news/local/Neighbors-on-edge-over-new-ra...

Would it be easier to force a half a dozen farmers/landowners to give up part of their property than thousands of house/apartment dwellers? Of course. But its still forcing people and that results in lawsuits which will drag things out.
The problem with the Obama map is that it still suffers from the same problem as the one posted: topography.

It is more a map to appease voters, without bearing into mind the cost of building it. If you look at it and go "oh wow, I can go from LA to SF up the coast", you of course can't tell that it would be madly expensive to build.
I saw that, and the point stands. I don't think an message basically telling someone their email was ignored is helpful. The existence of this feature could lead to a lot more emails being ignored, or even worse, lead to it being more socially acceptable to ignore someone's email, no matter how nicely written.
I wish Americans would (could) travel more, and see what other developed countries are like.

If they did this, they would realize why high speed rail makes sense in other developed countries but not in the US. Most other developed countries are tiny.

Aomori-Kagoshima (top of Japan to bottom) - 1928 km.

London-Moscow - 2885km.

Paris, France to Mosul, Iraq - 4522km.

NY-LA - 4469km.

And unlike the NY-LA route, all of the routes I mentioned have a lot of destinations in between the endpoints. For example, on the Paris-Mosul route you find Luxembourg, Germany, Austria, Slovenia, Croatia, Bosnia, Serbia, Bulgaria, Turkey and Syria. Between NY and LA there are Omaha, Chicago, Pittsburg, Cleveland, Denver and Vegas.

Even the short London-Moscow route passes through Antwerp, Dusseldorf, Berlin, Warsaw and Minsk.
The popularity of Excel speaks to what most common enterprise software lacks- flexibility and programmability. It's hard to construct what-if scenarios in most software.

In some ways, what has been the evolution of Excel in our company has been to switch to Google Spreadsheets, where you get the audit history, sharing, and version control solved, you can build web forms in less than five minutes to have people submit data, you get a decent amount of programability and web service API.
What does that word even mean anymore? According to his Wikipedia page there's not much redeeming about his social views. I guess you did say Tea Party "libertarian".

That having been said, I admire how he offers his rationale and using Facebook for good.
Airfare also relies heavily on subsidies, but fortunately investors keep investing in airlines, so it doesn't cost the public much.
I use Excel to bulk edit TFS (don't ask) work items. It works by having a plugin that lets you refresh and publish your changes back to the data source. Something like this for regular data would be ideal.
He'll have no challengers as long as his benefactors like what he's doing.
That's the "original" netbook, isn't it? I can't believe I hadn't ever seen one of those before.

At a quick glance, I think the biggest problem with it would be the 800x480 screen! If screen resolution wasn't an issue, I think a netbook could meet my criteria.

I'm sort of annoyed by the notion that "you can't prove a negative". It's true when we're talking about empirical evidence, but it's only a specific case of "you can't prove anything". There's nothing at all special about negatives. It's just that at no point can we ever say "Well, that's it, our confidence in this belief is now 100%" (even though we can get damned close). Of course, sometimes people say "proved" to mean "supported by evidence to the point that all reasonable people should believe it". In that case, you can prove negatives just fine.

I think that the "can't prove a negative" thing must originate from the subtler "it's hard to confirm the null hypothesis", but even that one isn't a hard rule, so long as you have lots of statistical power.
Then don't provide any information for them to sell except for an email address and what pages you look at.
Bigger seats (more leg room) and better food costs weight. Weight is a much bigger problem for air travel than it is for train travel. It's just physics.
Point still stands that the material used in the software development field has no nudity in it what-so-ever. So it's a crop from a nude, big deal. Is it also wrong if a non-nude image of a porn actress is used? What about a non-nude of a regular woman? She's been naked at some point, after all.

Why is the fact that it's from a nude shot considered demeaning? Because it's from a porno magazine? So what? I could kind of understand if it was a segment of an image from a hardcore scene but the full photo is actually quite tasteful.

If I ever get the opportunity, I'll use a crop from a nude male photo to prove my point. I would bet a year's salary that there would be no backlash.

There are far bigger issues in the world to be indignant about than this. We have people dying of thirst and hunger when we technically have enough resources to feed every person on the planet yet there are individuals full of anger regarding trivialities like this where everything is consensual, nobody was hurt and nothing bad happened.

I believe that the correct term for this is "theatre of the absurd".
You're right, Amtrak in the Northeast isn't very good. It's the only mode of transportation that completely prohibits carriage of bicycles. And simultaneously one of the few major rail services in the world to do so.
I've been meaning to try a tiling window manager. Right now I'm working with Unity, Chrome, and either Vim or Geany depending on my mood.
I'm inclined to agree that it's use would be uncommon, I've not encountered it in 30 odd years of reading papers and talking math (or rather I don't recall noticing it's use).

What I must point out is you make a weak case based on myopia- for example; in 15 years of working with tens of thousands of hours of high resolution radiometrics I've never once met and talked to a dendrochronologist who's looked at the radiometric signature of individual bands of Japanese pine trees.

It's my understanding that such beasts do exist.
I'm currently on vacation posting photos that I know are somewhat misrepresentative of the vacation and especially of my overall life.

But I honestly can't help myself--I feel like I have to have something good in my feed, sort of as a defensive portfolio of fun times against my friends future vacation photos.
I got the galaxy S3. So far it is amazing. It is great in all the technical features and despite the larger screen it is lighter and more comfortable in my pocket. And the battery lasts twice as long as my thunderbolt at its end of life.
Although I'm only 19, there are a ton of things I wish I could go back and talk to past me. Too many times have I missed out on opportunities and lost advantages.

Ah well.
What isn't "redeeming" about not wanting the government to bother people?
If you book in advance, the Northeast Regional is $50 each way from NYC to DC, versus about $30 for the Washington Deluxe bus. And a far more comfortable trip that's less likely to get stuck in traffic.
It would be amazing. But it smells very wrong. I suspect any improvements in battery economics is coming from better ~engineering~ manufacturing processes which has quickly eaten up low-hanging fruit, not from anything we expect to repeat.

I've seen the UI improvements, but haven't needed to use them so I don't know how good they are. If those work: Awesome! In a way, that's a victory. If CL incorporates the best things about 3rd party sites into their own site, I think that's a big win for consumers. If CL refuses to allow 3rd parties to exist because they are skeptical of human nature. Talk about the ultimate irony: a site that lives off of people's willingness to trust strangers being unwilling to trust strangers themselves.
While a lot of the comments here are focussing on other aspects of the article, I think the most basic actionable takeaway is we need a simple method of persisting changes made in Firebug/Developer Tools to the code. Once mentioned, it seems like a no brainer - why doesn't this already exist?
At least it wasn't Apple Maps.

That's only 2 years with no primary challenger, if the political fortunes of the Tea Party wane you can bet he'll see a challenger sooner or later. We're discussing a 6 year span here, career politicians can potentially spend decades in office depending on how little their constituency changes and how happy their constituency is with their voting record. The second part is critical as it's not usual to have a vote by vote explanation that could be used as fodder by either a primary challenger or a challenger from the other party.

Like I said, I admire the guy, especially if his libertarian-ism extends to areas that dovetail with the GOP and Tea Party on social issues like gay marriage or marijuana legalization. Coming out against SOPA was good but you never know if it was authentic or if he just saw which way the political winds were blowing.
It is an ecosystem, of course traders with fast computers would try to fill all the niches they can. Take a look at a broader picture: http://www-rcf.usc.edu/~lharris/ACROBAT/Zerosum.pdf

Is suspect those in "Panel C: Losers who expect to profit from trading but will not" are complaining the most.
It's probably an example of the exploration exploitation strategy. When young figure shit out, when older further develop the knowledge and expertise you started on while young. This is only a partial explanation, of course.

There are a lot of old rights-of-way that could be reactivated.

The real problem is economic, not political.

A NY-SF coach-class train ticket cost $65 in 1870. That may not sound like much, but that was 2.8 ounces of gold -- figure $4700 at current prices.

A first-class ticket with sleeping compartment cost $136 -- almost $10,000 in current dollars.

Wouldn't surprise me. Cook's biggest priority was/is supply chain dynamics. Endangering their relationship with Samsung would be a big red alert on his dashboard.

Either way, who cares? The lawsuits happened. I'd be more interested in a solid comment from Cook on the competitive landscape from here on out.
I said I've used Django before. The flaws I named are things that caused actual, serious problems in my project.
If this representative is intending to make his rationales public, he should choose a public venue.

But given the tracking information Facebook sifts via their extensive federation throughout the Internet today, I don't feel any inclination to make it easier for them by registering for their marketing programmes.
I disagree with Justin politically w.r.t. nearly everything, but I definitely admire his approach. He's also a genuinely thoughtful and nice guy, and very adept at explaining why he holds the positions he does.
I think most of the people saying "rip off" consider token $1k checks "ripping people off," considering implementing it correctly would require hiring talented engineers with expensive salaries. Given the giant holes punched in the original security implementation pretty much immediately after launch, he seems to have skimped on engineering talent preferring to instead pay these small bounties.

For example traders in equities can participate in "on close" auctions if they prefer to do so. No millisecond guessing, no bid/ask at all, pure double side auction. Yet only ~10% of the volume goes there.

You can open up your own ECN and offer fixed auctions every minute if you think this will attract people who feel cheated by HFT.
I could deal with a 15.6" computer if it meant decent resolution, but more 1366x768? Really, Asus?

Aside from that, it looks promising. I'm seeing it for about $400 at a couple places.
You don't have to link NY to SF. High-speed rail in the U.S. makes the most sense for linking the mega-regions. Chicago to Montreal is less than twice the distance from Bordeaux to Strasbourg and hits much bigger cities along the way. Birmingham, AL to Raleigh, NC is about the same distance hits similar sized metro areas.

Also: the fact that cars are driverless doesn't change the physics of 250 mph cars...
Open communication -> open journalism -> open education -> open science -> open politics -> open ?

I'm just trying to think of things that are still left closed. In 10 years will it just be weird that people aren't sharing things?
I read the parent comment as being about the social parts of his views, which don't really seem to be about the government refraining from bothering people. Defining marriage as between a man and a woman, and life as beginning at conception, are both pretty significant (attempted) exercises of the state using its authority to resolve ethical disputes.
The issue isn't humans vs computers, the issue is increased volatility with only a tiny improvement in liquidity.

Honestly, it just sounds like you need to practice the art of getting things out there. It's a really hard skill to learn, but you only learn it by releasing little bits as soon as they are at least usable, and never a moment later.

After awhile you'll be more content with imperfection, and you'll realize perfection isn't really worth it (or feasible). And if you do start putting price tags on things, you'll learn how to make your dreams a financial reality.

You are just graduating, many people never learn this. Start shipping something now, because it takes a good amount of time to learn and improve this process.

This is a terrible idea that for some reason keeps cropping up again and again. The major problem facing the Global Financial System(tm) is not high-frequency trading, it is large, illiquid, unhedged assets held by systemically important financial institutions. The nature of an illiquid asset is that it is traded infrequently, which makes it especially un-affected by a transaction tax.

OTOH, a tax like this may discourage high-frequency trading [despite it not being at all a systemic risk], but it also discourages certain legitimate and extremely useful forms of hedging, such as large notional currency swaps [http://en.wikipedia.org/wiki/Currency_swap]. And in the likely event that some esoteric forms of derivatives are exempt from the tax [they may be executed overseas, or just be exempted from the statute due to lobbying pressure] then it will encourage banks to shift trading activity from actual assets to much-more-fragile derivatives.

Bottom line: it's very likely that the net result of any Tobin Tax type implementation will be to actually make the Global Financial System(tm) more dangerous. And that's assuming you can actually discourage HFT, which is not at all clear. It will probably just migrate to some island that sets up a tax-shelter exchange.

I have no great love for HFT, but this proposal is the epitome of dangerous, populist feel-goodery. It makes no regulatory sense, and the fact that the Europeans keep threatening to hold hands and jump over this cliff together should not make you think that it is in any way good public policy.
i'm impressed that he's doing it at all. it's really hard for people who are not techies to realise facebook's intrinsic crappiness; at a superficial glance it seems like a fine choice for the purpose.
Maybe not in the primaries, but a viable challenger could come from the Democrats. Michigan still went blue in the electoral college for the Presidential vote.

Then again, between gerrymandering and demographic shifts individual districts can become more OR less defensible to incumbents.
Doesn't make me feel bad. I'm happy when I see my friends having fun. I couldn't care less if a friend posts a humblebrag. If he feels good about something, good for him. Friends on exotic vacations? Can't wait to ask them about it in person.

I don't see how any of these things should make us depressed.

EDIT: Yes my friends' lives seem more interesting than mine. Good for them if it's true, and good for them even if it isn't true, if it made them feel better to post it.
Your day isn't any less shot with 8 hours in the airport and on a plane than with 14 hours on a train.
Between Paris and Marseille are Dijon and Lyon. Between Chicago and Milwaukee are Franksville, Caledonia and Pleasant Prairie.
Michigan as a whole can go either way, but Justin's district is about as solidly republican as they come. Short of radical redistricting, that's not going to change (edit: I see that the 3rd district did become more balanced in the most recent redistricting, but it's still a pretty solid republican seat).

Those traders who didn't exit during the flash crash profited the most, what makes you think they will pull out the next time? On the flip side: those Market Makers that were forced to trade Facebook on the day of the IPO lost the most, when the system was totally broken, what makes you think they will handle the next problem better?

Anybody who's making a profit is almost by definition making the markets more efficient and less volatile. They buy when the price is low (pushing it up) and sell when it is high (pushing down).
