FRONT RUNNING

>"Quote Stuffing" is not the nefarious activity that Nanex portrays it as. It's generally the result of your algorithm screwing up

No, it's generally the result of an HFT intentionally trying to clog up the order stream (in order to push everybody else back), or trying to gain an information advantage.

>It provides no benefit to the trader

Now you're in cuckoo land.

Yes, i find it frustrating arguing with you too. What's worse is that you think using industry jargon will intimidate others into thinking you know better.
Voyager 1 is traveling at about 57,000 kph. http://solarsystem.nasa.gov/missions/profile.cfm?MCode=Voyag...

The 250k being fast enough remark was just a joke.

Yeah, space is inconceivably massive, that's why my main recommendation was that we focus on staying in our solar system for now. Autonomous robots can mine and build huge structures in space for us to expand to, or I guess we could build them on Mars, either way.

Many NASA scientists don't think that a warp drive is impossible http://www.space.com/17628-warp-drive-possible-interstellar-...

We can make antimatter, we can see trillions of miles away, we can talk to people on the other side of the planet instantly, we have computers that can simulate nuclear weapons, we have nuclear weapons, we can connect and talk to the human brain, and we can even theorize with pretty good certainty what happened to start the universe, a warp-drive or worm-hole isn't completely impossible in the near future.

Humans are not too far off from becoming gods. We can create life, we can put life on other planets, we can even improve ourselves by fusing with machines, shits crazy these days. [0]
What you describe as predatory trading is different from ubernostrum's scenario. In your predatory trading example, Little Billie trying to move a large block of shares, there are no existing orders in the book that match the entire block; so once the initial partial fill of Little Billie's order is done, he will have to change his offer for the rest of the block to move it. In this situation, yes, the predatory trader is communicating market information that might not otherwise get communicated.

In ubernostrum's example (which is also the one appearing in the OP to this thread), there are existing orders in the book that match the entire block. So the HFT in between adds nothing; the entire trade would have occurred at the original offer without him.
many people believe that over engineering is bad. It doesn't mean that it's OK to have crappy software, but that you should focus on things that matter. In other words, it's OK to do X until it's not.

On the other hand that's not an excuse for not understanding how things work and just having faith in some magic layer that somehow would just handle things for you. Doing so it could make it impossible to improve those parts of the system that are important without rewriting everything.
I'm having a hard time finding a use case. Unless Identitymind also handles money transmitter licenses (one for every state), which was not mentioned in the article, that is still a huge hurdle to regulatory compliance for exchanges.

The main use case for the bigger screen, that I've seen, is people watching video content. This is a very common use of the smartphone in places like Singapore. I was surprised how many people had smartphones and used them despite only having 3G service -- it's because they preload with video to watch on transit. I assume much of Asia is the same way.

Is it? When Apple introduced other screen sizes in the form of tablets, they required completely new layouts. Will they do that again for larger phones?

The 3.5/4 inch size is very much ingrained in the design of iPhone apps. For example: many apps require reaching into the top left corner for navigation - this has been a HIG recommendation since 2007. Reaching to the top left of a device hard to do on 4+ inch devices. Android and Windows Phone have mostly avoided this, meaning you can operate your phone without reaching into the top left corner. This considerably increases the things you can do on large Android/Windows phones with one hand.

That much of what seems solid and immutable is really a social construction, subject to change, affected by politics, argument and shared experience.

That's not really a fair characterization. 1990s Apple did indeed only iterate its Macs until Jobs returned, but they absolutely didn't stop trying to innovate – they just didn't do it with focus. I mean, Apple invented the PDA without its co-founder at the helm, and repeatedly tried to put a revolutionary operating system on the Mac, but failed due to institutional bloat and uncertain leadership.
> My point is these traders get to know things before other traders, thats not fair, everyone should see Bob's purchase order at the same time

How is that physically possible? How can an exchange make sure that I, living in Europe, get to see Bob's order at the same time as an HFT set up in a building adjacent to the exchange?

> and arguing that Bob has an unfair advantage because he knows what he's going to do before the HFTs know what Bob's going to do is just silly.

I'm not arguing it's an "unfair advantage". I'm arguing that your definition of a healthy market as being one where each actor has the same knowledge is not helpful, because this is evidently the case all the time in markets -- even those that seem to work very well.

At the same time I'm arguing that HFTs actually improve this situation (of market participants sharing the same information), instead of hinder it.
Yes, you could say "donations can have thousands of motives" in the same way about a single issue group. But saying that would be unnecessarily obtuse and argumentative - one supports a single cause the other supports thousands of stances.

You only donate to anti prop 8 if you are sufficiently opposed to gays marrying to spend money on it. I think it is by definition a bigoted act, and to use your words, morally repugnant.

The line of reasoning you've taken seems reasonable, but I don't think it works. So let's step back a little and take on an even more fundamental moralistic argument. The workers of the companies whose shares hedge fund managers trade may say, wait a minute, we're doing all the work and there's somebody out there creating models of our work in some dinky little spreadsheet and making more money than all of us by trading units of our work! From some moral standpoint, they are not really wrong - hedge fund managers are disproportionately well-compensated and they don't directly add value.

But what happens when you stop hedge fund managers (or really any informed traders) from arbitraging based on whatever research and analysis they do? Prices get out of line. And if prices get out of line or disappear, transactions either go away or are made on uneconomic terms. That's the problem with getting rid of hedge fund managers. This is why financial speculation is tolerated.

Now how does HFT affect this equation? Well, it's quite simple - they accelerate the social benefits of the actions of hedge fund managers while reducing their profits. When you're looking purely at the interaction between HFT and hedge funds, it seems like hedge funds are doing all the hard work and HFT is taking a cut for no reason. But when you realize that the product sold by these hedge fund managers to the rest of the society is better prices, HFT is bargaining with the hedge fund managers on behalf of the broader society and delivering the product quicker and cheaper.

The key to understanding this is that while the social value of hedge fund managers comes from efficient markets they help create, they themselves don't want efficient markets because they can't get paid as well in efficient markets. What HFT does is it brings about efficient prices a little quicker than they would otherwise.

Edit: The above does not preclude the possibility that HFT is harmful, but it limits the possibility largely to a world where hedge fund managers as a group are too poorly paid to be properly incentivized to do their work well. I don't think anyone's gonna go there.

Edit2: Another way to think about this is that hedge fund managers expressing outrage are trying to have it both ways - they want to get paid for their work but don't want to move prices in the process, even though price movements are their only contribution to society. And don't forget their access to liquidity comes from noise-traders who are willing to accept prices as they exist and HFT helps even the playing field between noise-traders and informed-traders, allowing the former to trade in sufficient volume to keep the spreads low.

But for the most part, it's not the buy-side complaining about HFT, because there have always been gate keepers and paying them has always been part of the game. Almost all actual complaints about HFT seem to come from people whose work is being replaced by HFT - the old school line-jumpers whose art no longer seems to translate to the brave new world.
>>6. The political opponents of charters have to prevent them from getting started. Where I live, the opponents have succeeded. But once charters become entrenched, getting rid of them is quite difficult. See NYC.

There was a recent media campaign against Mayor De Blasio's plans to review some recently approved proposals regarding public space for charter schools (specifically for the Success Academy[1]), which seems to have been largely successful in forcing the Mayor to backpedal somewhat.

Speaking to the quote above, Governor Cuomo just yesterday passed legislation further entrenching charter protections in the state which makes it more difficult for Mayor De Blasio to attempt restricting charter school funding or public spaces[2].

Who knew that the charter lobby was so well funded?

I'm from DC and start ups here are growing super fast. Thanks to many incubators and the hacker community here.
The most basic elements of electricity are volts (force) and ohms (resistance).

amps = volts / ohms
watts = volts * amps
watt-hours = watts * time

Bigger wire = less resistance, generally. So to increase amperage (and thus power), you need bigger wire. But resistance turns power into heat, so if you're trying to shove more power through, waste heat rises. Eventually, it can melt the solder joints that hold circuits together (solder is a very soft lead alloy with a low melting point). Meanwhile, too much power can easily fry the silicon of actual computer chips, and excess heat can cause other problems.

I can't say I hate Comic Sans itself, but I remember getting company-wide emails sent out in Comic Sans, like flyers for a bake sale. At that point I realized that it's the people sending them that I despised, not the font. Plus, when my daughter was in 3rd grade, she used Comic Sans for everything, and suddenly it wasn't so ugly. Meanwhile, her teacher sent out weekly class notes in Kristen ITC. If unicorns shit fonts, I'm pretty sure it would be Kristen

I am a big fan of HtDP, and Felleisen's in-progress 2nd edition of HTDP is here: http://www.ccs.neu.edu/home/matthias/HtDP2e/ . It contains many improvements over the first (completeness however is not among them).

That said, HtDP's focus is very different from SICP, and I would not sequence one before the other. HtDP focuses on a methodology for writing robust maintainable software. It emphasizes specifications and testing and functional procedures.

SICP is focused on computer science and emphasizes much higher levels of abstraction - e.g. the *nix signal processing model, logic programming, constraint programming, stack machines and dealing with concurrency. It is more directly an introduction to Computer Science [despite Ableson's questioning the utility of the term 'computer science'] whereas HtDP is more of an introduction to the practice of programming.

Philosophically, SICP is ok with the idea of placing the student in over their head, e.g. the digital logic simulator and various mathematical examples treat digital logic and mathematics and banking as domain knowledge that the programmer might not have, but does not need in order to create sound abstractions.

No, it is still an issue. Those icons are fairly small, if I have many tabs open it can take a moment for my eyes to scan across the tabs to locate the playing icon.

What chrome should do is take the capability that lets them know if a tab is playing sound and use it to mute that sound, unless the user requests otherwise or perhaps unless the tab is actually being displayed to the user.

What web developers should do is stop autoplaying things with sound. Unless your website is dedicated to things with sound and your user already knows that (read: unless your site is youtube, or vimeo) then autoplaying sound is always the wrong thing to do.
I find the already read text distracting. I would like everything within peek-ahead distance to be new text. Perhaps a white gradient below the line would work, or a three line tall moving white bar instead of the line.

I agree with most of what they say here - except using data.table. I much prefer using data.table structures with dplyr a far simpler more familiar syntax.
Indeed data.table - the object implementation - is brilliant and should just replace data.frame ...if that were possible.
That stood out to me too. Maybe they figure they'll have enough time to run some more simulations between now and 2350 when the starship is built, so it's not worth wasting a lot of time on what is mostly just a fun thought experiment.

I have the iPhone as a phone. I make calls with it, keep it in my pocket, and other uses are secondary (albeit common). Insofar as it's uncomfortably small for some uses, that's why an iPad is usually in arm's reach. Sure, 5" is more usable for many applications than 4", but ~10" is much more so. Make the phone more than 4" and I'm apt to just not carry it, as it won't reasonably fit in my pocket and looks/feels like a wall held to my ear.

iPad + iPhone Nano = winning combination. If Apple makes a 6" iPhone, I'd sure hope they at least retain the 4" version, if not shrink & optimize for a much smaller version. I need a phone that excels at being a phone and integrates well into the iOS ecosystem; got my tablet for applications needing a more complex/larger interface.
I remember when everyone was bagging on the iPhone for being 'so big'. "who is going to put that damn thing up to their face? They look hilarious! What is this, 1990?"

Really amazing how times change. I think it's because when the iPhone came out, no one could think of using their Phone for everything that they are now used for - so it just seemed like overkill. Now for a lot of people, it's their computer.
Technically it's more like "curl -i" rather than "-I" since it does a GET request rather than a HEAD request. Which is a good thing as the former is more accurate. There are rare occasions when a web server might be sending wrong headers which get overwritten with the correct headers from the executing code (I think one of OVH's portals suffered from this issue - though that may have since been fixed)

You probably might want to stick "-s" in there too; silence the transfer statistics which curl (annoyingly) adds when output is piped / redirected.

This is silly. Their reasons boil down to: 1)Android is hard 2)Android is hard 3)Android is hard 4)Because android was too hard for us, nobody downloaded our app.

Let me add a rebuttal:

There are many hungry Android developers out there. Developers who do not whine about how Android is hard. Developers who have actually invested the time and effort to be good at Android development.

If you write iOS first, and your app is a big hit, these hungry developers will clone your app within days and soak up 75% of the market that you ignored. Since iOS is so easy, many of them will port to iOS just as quickly. Their Android success will have a network effect. The 75% that loves the clone on Android will tell their iOS friends who will then choose the clone over your app.

That results in you writing an article on hacker news about how some guy just cloned your Threes/2048 app and is now doing better than you.

I have no sympathy for developers who are unable to compete because Android doesn't make development as nice/easy as iOS.

How did they ask people to locate Ukraine? Some of these points look like somebody accidentally clicked on a random spot of a map. For example, the dot below New Zealand is in the middle of the ocean (approx. -55.000000,176.000000). Some even located it within the US (Florida seems to be a popular guess). Have they found really misinformed people or is this noise in the data?
I did have a few doubts. If you watch the video, the battery is accessed via an app out side of settings. Maybe this is possible but its also not difficult to write an app that will mimic this. What I want to see is a DEAD phone that will not turn on charged to full.
>Why isn't HFT front-running? Let me attempt an explanation without relying on legalistic constructs.

That's quite funny since your defence of 'HFT front running' relies upon a fine legalistic distinction --- that the person who fucked you has no fiduciary responsibility towards you (HFT) vs. the person who fucked you having a legal responsibility towards you (broker).

Bottom line, though - they'll both fuck you.
> "is the result of a tricky conflict of business environments rather than deception."

Can't it be both? Intentional misrepresentation in the pursuit of a worthwhile goal is still intentional misrepresentation. I look forward to seeing Zidisha's response, but as it is this looks highly intentional and highly deceptive.

This ultimately comes down to the classic "do the ends justify the means" debate. It also leads to immediate suspicions of a slippery slope - if the founders of this startup are willfully misrepresenting the core nature of their business in furtherance of their goals, what else about them is negotiable?

I find that people throw out that line and keep to it about as well as people keep to their diets.

They make proclamations, but when it comes time to actually NOT put their kids in their Will, they balk. Once you have kids, they become a part of you. And jeez, wait until you have grandkids. That completely upends what you think of as "important".
