All would have been fine and well



 I've been doing this since '86. It wasn't really until 2008 and 2009 that we noticed the explosion of quotes, of price changes for stock, without an a panying explosion of actual trading. Normally, you'd see the price change once or twice a second -- now, a hundred times, or a thousand times. Just a little quick calculation on the calculator, and a knowledge of the speed of light, tells you, 'Hey, wait a minute, you guys are changing the prices faster than anyone can physically access them,New Released Mercedes Benz AK500+ Key Programmer with EIS SKC Calculator so why are you blasting that all over the country on the consolidated feed?"This is, in your view at least, the result of Regulation NMS issued in 2007 by the Securities and Exchange Commission.

With Reg NMS, it essentially took x amount of available stock at one place, and made it one tenth of that x at ten different places. The regulations, as they were written and they were understood, were that routing of orders for stock would all be based on what they called a SIP, a security information processor. The SIP would tell each exchange if there were a better price somewhere else. If so, the order had to route it to that other exchange, which guarantees you get the best price available on any of the exchanges. Where does the best price e from? It es from the SIP, also known as the consolidated feed. It's really what goes along the bottom of CNBC or financial sites.

All would have been fine and well, or at least, it would be a lot better than it is today, if they actually used the SIP. Instead, the exchanges created these direct feed connections, which is a way to get the prices faster, which is actually illegal under Reg NMS. That's the big issue I have. Reg NMS is very clear: exchanges can't give this market data to anyone else in any other way faster than they give it to the SIP.TOP3000 Universal Programmer High-frequency traders are taking advantage of the exchanges illegally giving them this data sooner. If anybody is going to get arrested or busted or fined over this, it probably won't be the high-frequency traders. It's going to be the exchanges. That's what the NYSE got fined $5 million for in 2012. The SIP is the core of that piece of regulation. Without the SIP, all of Reg NMS falls apart.

Getting back to Lewis's book



 It can be the same group of stocks that processed by the same puter. That's what quote stuffing is, and that still goes on today. That should just disappear, if they weren't doing these games any more, but they are. They're going to roll out this new laser technology that gets from Carteret to Mahwah in an obscenely small amount of time. It's getting on the low-microsecond range. There's a reason why they're willing to pay for that.This has not changed at all. They've just gotten more sophisticated at hiding it. Instead of doing it solid for a second, they'll do it ten times as much, but they'll do it in a tenth of a second, so that the exchanges, which measure traffic on a one second interval, won't see it. It will be invisible, but it has the same impact.

Getting back to Lewis's book, IEX just opened in December. They were still pushing Thor around a year ago.That book is not old at all. It is spot on the money.Your own pany, Nanex, in Winnetka, Ill.--when and why did you start it? How do you see your place in all of this as a critic of high-frequency trading?
Back in '86, I was collecting everything traded on the CME onto a floppy desk, and selling that historic data from the Chicago Mercantile Exchange via Bulletin Board System. That was the precursor to the Internet.How about that!We actually had cell phones back then. We even had a real-time system once. We were transmitting real time futures charts into your car you'd ride around, and on a laptop hooked up to your cell phone, you'd see real-time, streaming charts. I've been here since the beginning.People who know me know that I'm all about data. I'm very scientific about it.

 I'm not going to publish anything or say anything unless I'm 100 percent sure and I've verified that that's what it is. I'm a very quiet person. I am not one who -- I'm a programmer at heart. That's what I enjoy doing. It wasn't until the flash crash came along: May 6, 2010, at 14:42:44 is when it overloaded.We ended up processing over a billion quotes that day. It seemed to me the SEC was having trouble assembling data. We had it. My pany, we can replay any market day that we want. I made the fateful mistake of saying to one of my programmers out in California, 'Hey, let's see what we can do with our data.

The vagaries of English language



Wilcox: The vagaries of English language. We strive to recognize meaning, not just words. Plus, the depth of material you need to handle the long tail of all possible conversations that the user could initiate. We obviously can't handle everything, but we handle an awful lot. Here's an example of a prize-winning 15-minute conversation Angela had with a judge during the 2012 ChatbotBattles. Multi-Diag Access J2534 Pass-Thru Device It's an example of something which is "close" to great, with only minor flaws to reveal it's a chatbot.We use ChatScript, an open-source natural-language engine I wrote. It's the most powerful tool out there for creating conversational agents.What are the cues that I can use to know for sure that this conversation, which we're doing over instant-message, is with a human, and not with a chatbot?

Wilcox: You'd best ask things that puters are lousy at, like physical world inferencing. For example, "If I keep pouring coffee into my cup, what will happen to the book on the table near it?"PORSCHE PIWIS Tester Long sentences with plexity are also hard for determining meaning by puters.At the World Turing Test petition, a judge asked, "If I stab you with a towel, will it hurt?"And what was the answer?Wilcox: We weren't ready for it. You never can be. So we did something useless like quibbling.Are there specific challenges to creating AI aimed at children?Wilcox: Absolutely. First, voice-to-text is really hard with kids' voices. Second, childrens' vocabularies are limited and limiting.And third, as an adult you can't just write what you would easily write and say.

You have to scale it to a child's cognitive abilities. Angela wasn't so bad because she was an 18-year old voice, whereas, we're working with Geppetto Avatars on a children's health management app that's targeted for 6-year-olds, and it's been a real problem for us to think like a child and write for the child. The child's sense of humor is different from ours, and they love repetition.What is the World Turing Test petition like?Wilcox: It's a random mess. The qualifiers ask human knowledge questions like "which is bigger, a pine nut or a pine tree." And if Tom is taller than John who is taller than Sue, who is the shortest. The top four scores then get the human judges in petition, where they can do anything.

Runway Model And Tech Programmer



Now it's time for the latest conversation from our Women in Tech series. All this month, we're speaking to innovators in tech, and we're talking about the best ways to encourage young women to consider engineering, puter science and other tech fields as careers. Now not many of us think of tech as glamorous, but fashion model and programmer - yes, you heard me right - Lyndsey Scott, is defying the stereotypes. When she's not busy modeling for Calvin Klein, Prada and Louis Vuitton, Lyndsey Scott creates apps - two of which were recently picked by Apple. And despite having walked the runway for Victoria's Secret, she is still proud to call herself a nerd. And Lyndsey Scott is with us now. We e. Thanks so much for joining us.LYNDSEY SCOTT: Thanks for having me.

MARTIN: So which came first, the beauty part or the geek part?
SCOTT: I was probably called a geek way before I was called a beauty. I definitely wasn't a model when I was in school, but I never called myself a geek back then. It was more of a painful term than a plement, but now that people are using words like geek and nerd to describe me, as long as it means that I'm smart, I'm OK with it.MARTIN: You're going to fly your geek flag high now, right?SCOTT: Sure.MARTIN: So when did you discover your love of puter science and all those kind of related areas? Is it something that you grew up with? Is it something that you kind of discovered just by kind of noodling around?SCOTT: I first started playing around with puter programming when I was in middle school.

I was given a TI 89 graphing calculator. I started looking through the documentation, and realized I could make games on my calculator. So I didn't see it as puter programming at all at the time, just as a way for me to have fun games to play with.MARTIN: We've spoke to a lot of women and girls in tech fields, and a lot of them say that they started kind of getting messages surprisingly early on that tech wasn't supposed to be for girls. I mean, that they weren't supposed to be in it. Did you ever feel that way?SCOTT: No not at all. Programming wasn't something that I was deterred from at all. In fact, my father was a puter programmer when it was in zeros and ones. Right now - nowadays he types with one finger at a time on a puter, but he was involved with puter programming himself.

But a lot of male programmers increasingly say that that they feel it



Being a software programmer is one of the best jobs these days for your pocketbook and your job security, but it can be incredibly bad for your mental health.Two things are going on that are literally driving programmers crazy.One is something known as the "imposter syndrome." That's when you're pretty sure that all the other coders you work with are smarter, more talented and more skilled than you are. You live in fear that people will discover that you are really faking your smarts or skills or a plishments.Women programmers frequently confess to suffering from imposter syndrome, and that's not surprising. The syndrome was actually first documented by psychologists Dr. Pauline Rose Clance and Dr. Suzanne Imes as a particular issue for successful women. It's also the subject of a number of self-help books geared toward women.

But a lot of male programmers increasingly say that that they feel it, too.These people tend to apply extremely high standards to themselves and not to others.Nissan Consult-III Imposter syndrome is  mon in professions where the work is peer reviewed. Writing software is just such a field, particularly open-source software where anyone can look at the code and change it.The trap of imposter's syndrome is that programmers think they need to work harder to b e good enough. That means spending more time coding every waking minute and taking on an increasing number of projects.That feeling is called the "Real Programmer" syndrome as named by a post that went crazy on Reddit last week.  The Real Programmer lives only to code. Redditor big_al11 explains:

A Real Programmer is someone who loves programming! They love it so much that it's what they spend all their time doing.the Real Programmer doesn't really consider it "work".a programmer isn't a Real Programmer when they don't volunteer to work 60 to 80 hour weeks for no extra monetary pensation, remember because it's "fun".It permeates the industry's culture.If you want to succeed as a programmer you have to at least look like a Real Programmer .... So you get people working evenings and weekends just for appearances and they start to burnout.Nisscan Consult4 That programmers are expected to work insanely long hours isn't new. But this idea that they are doing it of their own accord, for the sheer joy of it, is new.

But what I've learned is that you really just have to be yourself



 So, I bogged down and taught myself how to code. And after three days later, I created an app.So, what happened next seemed like that of a miracle; my app was downloaded in over 40 countries in its first week and within a month, it was being represented in over 1000 cities around the world. Who knew that so many people wanted to know what to wear according to the weather? I didn't. It just seemed like a stupid idea that thought of in my dorm room. I never knew that other people would like it.For a while now, I've been wanting to write articles that have a bit more of conversationalist tone. I'm not much of a blogger, but I think that it's important. I just think in the past we've met tech entrepreneurs, but it wasn't until after that we learned of their stories. Although I may never be of the likes of my tech heroes Mark Zuckerberg and Bill Gates I want people to see my growth as a person and my past. This is a journey that I want to take people on.

So far, it's been great but particularly the letters. I've received so many of them from you all around the world. Your stories of triumph and bravery and fighting against the body politic just inspires me more and more every day. I must admit that when I initially received the invitation from Arianna Huffington to be a guest blogger for The Huffington Post, I was really afraid of what people would think of me. My dream has always been to tell my own stories of bullying and inspire people and make them feel better. But now that I was being given this international opportunity to tell them through the Mecca of blogging. I was really scared at first.

But what I've learned is that you really just have to be yourself. I think that's the secret to defeating any fear you have. I live in the belief that we were all put on this planet for a reason. And there is always going to be a time when you're afraid to do something because of the mean things that people are going to say. But it's because you're special. Everyone that I've met who's achieved their own dreams were outcasts at one point in their life because everyone around them was just doing the normal thing. But trust me, i's really a wonderful thing that you'll look back on and laugh about after you do achieve your dreams.

Remember when stand-alone EFI systems seemed beyond the reach of the average car guy



Remember when stand-alone EFI systems seemed beyond the reach of the average car guy? Oh sure, the"puter geeks could get it to work, but for those of us without a"puter degree, the risks just seemed to outweigh the benefits. Well, now that the EFI"panies are well past their infancy, anyone who really wants to take a bit of time to learn about them can have a great performing EFI system in as little as a weekend.But what if you don't want to run a single or pair of four-barrel throttle bodies? What if you have or want a Six-Barrel car and want to keep it that way? And what about using a Shaker hood?

That's the issue that Muscle Car Restorations came up against recently,X-VCI For GM MDI when the owner of a '70 Challenger wanted to upgrade from a 383 four-barrel to a 512-inch stroker and a Six Pack. Sure, repop carbs are available, but EFI on a six-barrel throttle body sounds cool.It just so happens, that Bruce K. Bridges, founder of F&B Performance Engineered Products, has been working with Chrysler two-barrel throttle bodies for well over a decade, and has been building billet aluminum versions for some time now. He has"e up with a"plete six-barrel setup that will work with either FAST's XFI or EZ-EFI systems. Just like the original Six-Pack cars, you can run around on a mild two-barrel and still have as much as 2,300 cfm at your disposal.

Because F&B builds their throttle bodies from billet aluminum instead of cast aluminum, they can offer bore sizes of 44-50 mm, and claim that they will flow more air than any other throttle body of the same size. The billet construction also allows them to build-in larger inlet areas than stock, use tapered flow paths for maximum ram effect,32MB CARD FOR GM TECH2 and most important in this case, they are"patible with factory air cleaners and shaker hoods.F&B also supplies an Edelbrock Performer intake that has been fitted with the proper injector bungs and vacuum ports for the MAP sensor and etc., so you can get a"plete bolt on kit that even"es with custom spacers so your shaker hood will end up at the correct factory height. You will need to upgrade your fuel system, but we'll show you what you need to do to for that as well.
