"My position was that no large banks or hedge funds or other concentrations of political power were against it until relatively recently. Which is completely true."

I mentioned several giant hedge funds (orders of magnitude bigger than the entire HFT industry) that have been arguing against HFT for a very long time. Further, the first article I found on a 2 minute google search, mentions a large fund that was speaking out against HFT in 2009. This is as simple of proof as I can provide that your position that HFT is not opposed by large finance groups as untrue.

"Frankly I don't know how you're still defending barclays for selling an service promising freedom from HFT "

Not once in this whole thread have I defended Barclay's and trying to paint me with that brush is either a sign of extreme obtuseness or terrible rhetoric. What I argue is that the reason Barclay's needed to defraud their customers is that their claim (and all other dark pool's) claim that they could provide a better trading environment by excluding HFTs has been historically proven as false. Traders are not dumb, they move to the venues that provide them with the best trading environment and that has continued to be venues that allow market makers EVEN IN THE FACE OF FRAUD.

No matter how many times you paint HFT as "predators" or "sharks" or as "spearing whales" you've yet to describe a single behavior attributed to HFTs that is in any way unethical or illegal.

[edit: having to work around HN reply rules, I apologize]
To the reply below about BlackRock. Do you really think it is a realistic comparison to compare BlackRocks recent profit (2013) to one of HFTs best year (2009)? At the very least you should have mentioned that it was different years.

"Were this true, dark pools would not exist in the first place"

Except that there are all manner of product offerings that don't make sense for their clients. The easiest analogy in this case is extended warranties. "If extended warranties were so bad why do so many people buy them?" Of course this is a ridiculous argument. People buy extended warranties to hedge risk that is over rated due to warranty salespersons. The exact same way dark pools are.

" There is a link I posted below in response to you that describes such a strategy"

It does no such thing. It hand waves a lot of semi-technical non specific jargon around an idea that is easy for people to get upset about. I could just as easily write an article about how multicast networks were dangerous. It wouldn't make it so.
Haven't we seen this movie about the clash of egos and a non-standard "standard" before? It didn't end well and no one seems to have benefitted from the exerience.

A rose by any other name would certainly not be a rose to the casual reader. "Smakdown" (for example) would require a Google search to inform that reader. We'd loose 1 minute to see that "it's a new standard [ forked from | based on ] "Markdown by John Gruber".

Calling it a rose would mean reams of existing code that would generate errors on this new "Rose" input.

Names matter when they break something. But only until we learn the new one and write new code.
In the CMS itself it's handled by Elastic Search pretty easily. For the frontend, I used Swiftype's free version. It's what powers Webhook.com (itself is just Elastic Search as well, but adds some niceties like analytic).

> While most cops are simply doing their jobs like any other profession,

The problem is the following -- those "good" cops doing their job protect the bad cops. The whole "blue code of silence" thing. Those are not good cops doing their job. The are bad cops. If anyone has not spoken out when a colleague has been abusing their power, they have become a bad cop.

One can argue this is just human behaviour -- us vs them. That maybe true but when police have so much more power vs regular citizens, that kind of behaviour is amplified and exaggerated many times over.

To put it another way. A corrupt shoe salesman can only be that dangerous. A corrupt cop can do a lot of damage to a lot of people.

So that is the reason I have essentially stopped saying "oh just a few bad ones, the rest are good and law abiding". I think I moved to the default that all are corrupt and either engage in abuse or cover up of abuse unless I am presented with evidence otherwise.
If there was irresponsibility in the disclosure, it was in waiting so long, presumably allowing many more people to sign up and become exposed to Coursera's negligence.

The cargo cult of "responsible disclosure" needs to die. Responsibility lies with us, the developers.
A tax break and a subsidy are the same thing as far as taxpayers are concerned. As it turns out, tax breaks are considered more politically palatable, but the effect is the same--all taxpayers pay more money than they otherwise would have, to make up for lost revenue from the tax break.
I can't say with absolute certainty that it's called this across the entire country, but in my part of Sweden it's called "spunnet socker", which translates to "spun sugar". Certainly seems more appetizing than beard or hair at least. :)

Dead store elimination is a really important optimization, and it comes out of bog-standard compiler optimizations like SROA on SSA form IR. You really want your compiler to perform it for acceptable performance.

this isn't meant to be an argument that no tax ought to be paid, simply that it is not a loss for our country if fewer taxes are paid. If you are worried non shareholders pay more and gain less, they are free to invest, but shareholders inevitably pay capital gains tax.
>> I always had the expectation that accelerators are about helping young startups to figure out what they do.

Not to be pedantic but I see accelerators as accelerating a startup. Try to picture something accelerating really fast, but apply that concept to a startup. I think it's a bit of a myth that YC helps young startups figure out what to do.. they are more about helping great startups move and grow faster.

>> I am very surprized by this statement: "In general, we don’t start introducing startups to investors until a maximum of 10 days before Demo Day"

Simply because it's better to focus on the product and get more users before demo day. Raising is just a way to grow faster.

>> am curious to hear YC founders on their thoughts of accelerators, especially, the traction you have or your peers already had before YC.

Loved the experience, would do it again. We had great traction for a very early startup.
I know you didn't say this, but it's important to remember that dinosaurs aren't reptiles. They're dinosaurs.

You should keep in mind that the memset call is almost guarenteed to be inlined. So your code actually looks like this:

void
dosomethingsensitive(void)
{
uint8_t key[32];
/* ... */
int i;
for (i = 0; i < 32; i++)
key[i] = 0;
key[0] = key[1] + 1;
}

Assuming the optimizer is sufficiently smart, then it'll remove that 'for' and it'll remove the addition after it in the same fashion.
"They also mention that it would have had to spend almost the entirety of it's life eating, rarely even sleeping, and that simply falling over could have greatly harmed it."

Probably literally meant people from the US. In English, standard usage assumes "America" to mean "USA", and references to the region are referred to as "the Americas" (plural), with the north/central/south regions being considered largely separate. There's very little value in referencing the majority of the residents of the western hemisphere as "Americans", as there's really nothing they have in common beyond that.

It seems like a pretty safe bet for the state though. $1B not collected in exchange for $100B benefit overall. And a bunch of high tech and manufacturing skills added to the labour pool, which could attract other companies for less concessions in the future.

It doesn't seem as difficult competitively as eg picking stocks on wall st is what I'm trying to say.
The analogy doesn't hold. In cases like this everybody wins - the money 'given away' by the state is merely virtual, both sides and the economy as a whole end up with net gains. In the case of net neutrality, the big guys get rich while customers suffer from poor service, and no value is created.
>Of course they didn't. Professional market participants don't whinge. They go to venues that provide the services they want, namely cheap liquidity.

If they prioritized liquidity above all else, as you appear to think they should, they wouldn't be using a dark pool in the first place. They would have been using a public exchange.

>When you say "they got away", you do know that those market participants moved to open exchanges where HFTs "run rampant" and stopped paying Barclay's for their service.

Yes, I'm sure they all left after it was revealed that Barclays was lying to them and allowing HFT predation on their trading activity.

>what do you mean when you say HFT shark?

An HFT trader that parasitically extracts value from a non-HFT traders - often institutional investors (e.g. pension funds) putting through large orders. The link I put below describing a 'whale' to you explains just one parasitic strategy.

>If the point was extracting more fees why did Barclay's subsidize HFT trading? They charged HFTs an order of magnitude less than their clients

A) Subsidizing != Charging lower fees
B) Citation, please (that OVERALL fees were higher, not just fees per trade - HFT will obviously get bulk discounts).

>that was a central part of the complain.

The central part of the complaint was that the service was advertised as HFT free when, in fact, it was not. The marketing literature is all out there saying this.
Well, yes and no. Ultimately yes -- Coursera should have been more diligent about considering the implications of their API endpoints.

On the other hand, telling the whole internet before they've addressed the items he told them about, and potentially opening them up to more scrutiny (likely less white-hat like) is not an especially helpful thing to do.

This blog article has huge technical problems and is not a financial community technical journal. It is in fact a political blog with it's own agenda to push. Even without these giant warning signs what they describe in this article is not illegal or unethical.

After reading this article your assertion is that it is unethical and/or illegal for market makers to use standard market orders that are filled in legal and standard ways as price information signals, but it is not illegal and/or unethical for large market participants to hide their order flow with specialized orders and/or venues?
Yep, everyone who's bought something "Made in China" should know about how job-producing factories can and will move to the cheapest location.

Nevada giving incentives to have a factory built is no more corruption than tariffs to protect imports/exports is corruption. You can argue if it's a good or bad thing, but it's definitely not illegal nor should it be illegal.
We have federal taxes that are supposed to pay for general national welfare. Beyond that it is not clear why the state of California "deserves" to collect taxes more than Nevada, which offers more for less.
That would presumably solve this issue. Perhaps that is what they will end up doing -- hard to say since they haven't addressed this issue yet. The author was guessing at solutions that might help (though, as you've noted, he was mostly off base).

No. He is only objecting to the name. He holds rights to the name[1], similarly to Linus Torvolds holding rights to "Linux"[2]. Anyone can fork Linux, but forks lose the name unless Linus approves. Otherwise the name loses meaning and value fast.

The only sustainable way to insure everyone is to lower the cost of healthcare. My insurance premium went up 15% since Obamacare was introduced (as opposed to "mere" 11% in previous years). I don;t know what I am going to do next year.

This flies in the face of the claims that "if everyone pays in, it will be cheaper for everyone". Not happening.

I agree that having universal coverage is great (and long overdue), but there are much better ways of achieving it.
This exact deal is not open to any other company. This isn't a policy that's open for everyone to take advantage of in the way that some tax breaks are, e.g. for film makers.

Just because other deals like this have also occurred doesn't mean this one isn't also singular and specific. Don't know why you're getting pedantic on this.
Great article. Thanks for sharing your experience
Your eyes are only made for a certain frame rate. Any more and your eyes will ignore it, but your brain will need to piece it back together (ie nausea). Any less and it will seem choppy. It's a very very thin line at which it goes from nausea too choppy/laggy.

Not that a few milliseconds of latency really matter, but if you don't care about 2 milliseconds here and another 2 there, they start adding up. It's much better to try your best to have the lowest possible latency.

Maybe the objects-as-agents could pass around a struct? E.g. I imagine the Store_Manager (driver class) could call (like on the telephone) the Accountant and ask to submit a report (struct) of all the inventory that fits the parameters. Or would that be another anti-pattern?
Then we have hundreds of thousands bubbles happening on the daily basis. Tons of people invest in real estate, and when those projects miss projections, some money (or opportunity cost) is lost.

IIRC, Intel shopped for a location for a chip fab
back in the 1990s - Pentium F00F bug timeframe - and narrowed
the possible sites down to 12 or 15, then to 8 or 10,
etc. and finally to 3 states, and basically asked them
to bid with tax credits for a ~2 billion project, and
they all gradually raised their bets until nobody would
offer more - and then Intel accepted all 3 offers -
New Mexico, Oregon, and one other. Smooth move
on Intel's part, and it worked out for them. The
"winning" states had more mixed feelings.

"they" aren't reading email and what does it even mean "before I open it" - they host it!!! It's software that "reads" gmail. If you don't want google reading your email, then simply host it elsewhere. Nobody is forcing you to use gmail. It's patently obvious that they use gmail and the usage of their other free services to garner more information to maximize their revenue. Don't like it, don't use it. It's a simple as that.

It frustrates me no end to read stupid comments like yours. Of course they use what you freely give them to their advantage. There are plenty of email hosting options, viable search alternatives, viable mapping alternatives etc etc. Google don't have a monopoly on anything. They make you a simple trade; compelling products in return for profiling you, what you say, where you go and what your search intents might be.

I know perfectly well where google's profits come from. Who reading this site doesn't?

Were this true, dark pools would not exist in the first place. Traders would have stuck to the public exchanges and paid their (lower) fees.

>No matter how many times you paint HFT as "predators" or "sharks" or as "spearing whales" you've yet to describe a single behavior attributed to HFTs that is in any way unethical or illegal.

False. There is a link I posted below in response to you that describes such a strategy (spearing the whale) in precise detail.

Not yet. But I'm a bit worried about the future. The governors in California and Texas are going to take quite a bit of flack from this. The bidding war for these types of projects is likely to get fiercer. As competition between states increases, the margins will get ever slimmer.

>You can argue if it's a good or bad thing, but it's definitely not illegal nor should it be illegal.

That doesn't make much logical sense. If you think it's a bad thing you would want it to be illegal so that it doesn't happen. Just like if you think tariffs are bad that they should be illegal.

Maybe not illegal in the criminal sense, but illegal as in regulated to not be allowed makes perfect sense.
