They are only accepted at the midpoint.

EDIT:

It's just a feature of the matching engine. It's not really that complicated. The venue, let's say BZX, accepts an order from you to display a BID for 100 at 20.01 and you flag the order and tell the matching engine you'll accept 20.015.

When someone comes along and wants to sell, let's say Grandma Sue, she might say: Sell 100 at MARKET. The displayed market is 20.01 / .02. With your bid in the market Grandma will get matched at 20.015, a .005 price improvement over the displayed bid of 20.01. This is a good thing.
This one actually sounds pretty awesome.
> This certainly works, but the communicate method is rather clumsy.

I think this needs expanding. I don't see anything wrong or too clumsy in the communicate method.
The biggest problem I have with CI as a specific application framework is the insistance of being extremely backwards compatible (PHP 4 support was dropped less than a year ago, and they only very recently stopped supporting 5.1). I understand why this makes sense for Ellis Labs (the developers of it) since Expression Engine is designed to be deployed by clients. If you're picking a framework to use, pick one that allows you to take advantage of all the improvements made to the language (PHP 5.3/5.4 bring a huge number of improvements over even 5.2). I also have a number of fundamental disagreements with how CI is built - no proper autoloading system, a weak routing system (no URL helper/parameter mapping), no request/response objects, odd controller instation and library/model loading (generally fairly disconnected from standard OO design)

If you want a full featured framework, Symfony2 is a good everything including the kitchen sink although it's a bit more Java-esque (which make sense since much of PHP's OO design is based on Java). http://symfony.com/

For something lighter weight, Silex is based on the Symfony2 components, so it's super easy to pull in more components as you need them. http://silex.sensiolabs.org/

Even if you're not using Symfony2 it's really modular and easy to integrate with other frameworks - we're running CI as our base framework due to legacy reasons, but all of our new work leans heavily on Symfony2 components.

Sounds nice. Some questions:

- I assume you did the tests with direct SQL statements without any ORM? How would an ORM affect the test's performance (with an Node.JS-ORM of your choice, e.g. sequelize)?

- How does Node+VoltDB compare to i.e. Node+PostgreSQL or Node+MySQL

- What does in memory SQL exactly mean? How is data made persistent?

Midpoint orders exist on all the venues. All but EDGA/EDGX provide some rebate for resting a midpoint order. DirectEdge charges both sides for what they refer to as "midpoint match".
There is more money in taking advantage of the user.

That's correct. They display at a whole penny price but execute at the midpoint. They may also execute at an offset for the market or primary.

Someone please correct me if I'm wrong, however I believe that VoltDB is highly tuned for a specific usage that benefits lots of small operations on large amounts of data. It is less beneficial, if not detrimental, for large operations on medium or large amounts of data.
Thanks for clarifying that about point 2, I didn't realize that the fact that it would be entered as evidence later on was relevant to his showing it now. Very interesting how the legal system works.
I understand your statements as coming from someone who is looking for an opportunity and frustrated now. Wait until you get a job( which you will) and 'settle'. If you are already employed or , looking for fulfillment outside your 'day job', this thread might be more relatable to you.
This has some basic crypto issues, but that doesn't matter much because like the related "server proof" web crypto apps, all the security of this system depends on the server not lying to you about the AES implementation it's sending in its JS.

A malicious server admin or anybody who pops this server can read people's content just as easily as if it hadn't been encrypted at all.

People obviously enjoy writing these kinds of applications, and more power to them if they're learning from the experience, but I just don't get the attraction. Could someone consider taking the energy they were going to invest in shoehorning 1/8th of PGP into Javascript and just write the Mozilla and Chrome extensions to expose a C implementation of PGP/GPG to Javascript?
"As we have become less worried of posting photos of our children and to display our location to a level of accuracy that would have scared us ten years ago, so we have started experiencing death in unexpected ways." - I know I certainly haven't, and frankly the whole "memorializing" of someone's Facebook page is distasteful to me. Nothing like commoditizing my dead childhood-best-friend so that everyone can feel better. I wonder if Facebook will show ads for funeral services in my timeline after I die?
Hiring Designer & Mobile App Developer: Let's fix the car repair industry
Car repair industry is completely broken. Not only it is such a waste of time to deal with car problems, but you can bet that you are never paying a fair price for anything. We have made it our mission to fix the car repair industry, and we are fortunate that YC and an incredible group of investors are supporting us: www.angel.co/yourmechanic.

We are looking for an iOS and Android app developer. Ideally we prefer someone who has experience building apps in both platforms, but we are open to hiring two engineers (one for each platform).

Also looking for an awesome user interface designer. You will be responsible for all the landing pages, website, mobile app design, branding on the vans and the uniforms....

Salary, equity, benefits, lunch and the best computer equipment - as you would expect. But you also get free car repair and maintenance - a perk no one can beat ;-).

Send us your portfolio instead of a resume. (art@yourmechanic.com)
Just use communicate()... it's just a 30 lines script. I would understand the complaint if he was doing some work which involved calling a lot of different commands (suggestion: abstract it into your own function, add missing methods to StringIO wrapper), or used pbcopy for many purposes (suggestion: create pbcopy function), or wrote an application which has the main purpose of calling other commands in a nice way (suggestion: use envoy).

But here? Really?

for f in $* ; do
(echo ${f/.txt//} ; cat $f) | pbcopy
osascript < the_copy_script
done

And let's move to doing some useful things instead. I'm not even sure why he picked on python in this case, since it's the notes application that has issues with interoperability (is it really the easiest way to interact with it? by simulating clicks?)
I'm afraid this part of a larger trend - people are trading freedom for the promise of safety left and right.
Japanese Conveys Information More Slowly Than Other Languages
this will be mod'd down but it's the truth. Below I reveal entrepreneurship's REAL dirty little secret.

it's that if you're talking to an early founder about helping in any way, shape, or form, you are going to get screwed - the question is for how long, and for how much.

is it just going to be your opportunity cost at accepting the wage that you were offered and any other compensation? or are you even going to get paid what you agreed to?

the true dirty little secret to entrepreneurship is downright marxist(3): it's how much value you can steal from your contributors. but wait, why does that work in a capitalist system? everyone sets their own price. Ah, but the thing is, people expect you to at least stick to agreeements. that's how zynga became zynga. (1)

it's like hollywood accounting - how about fifty thousand and five percent of net profits? My last three films each grossed over 500 million. (Author thinks: YES. If this thing makes anything like that, 5% of net profits is going to make me rich. The film grosses a quarter billion, net profit...0..)(2)

zynga is entrepreneurship's dirty little secret.

you can mod me down now.

summary of my whole commment: the dirty secret to entrepreneurship is that it's a sucker's game for a talented developer to come on board as an early non-founder.
thanks for posting this - i actually had a similar start with my start up, artmeme. after hearing "expensive hobby" to "business hobby" i can relate. took me over 2 years to find out what the art community needed. this all through the on and off line community i built. get a newsletter going if you dont have one already. i'd love to hear how i can improve and generate some cash flow. i think you got the concept there - just continuing to build the community - you'll figure out what's needed after surveying musicians to see what's lacking in their community. this might be a good udemy for musicians down the road...i also praise you for reaching out and getting feedback. not many people can put their pride down for a second. would love to hear where you end up going with it. good luck!

You mean legally our ethically?

Legally I have absolutely no clue. That's why they're in the court room for. At the end of the day it's up to some random people's opinion.

Ethically, I'm pretty sure it does by far more harm than good. Because of the whole standing in the shoulder of giants, and common as air arguments. That most here are very aware of. The only counter point would be the economic incentive that copyright gives oracle. But that's meaningless because we have mountains of evidence that people will invent great languages anyway.

I think if you consult the literature you'll find that the prevailing trend is for markets to become more continuous rather than more discrete. Continuous markets help with true price discovery. Our markets are continuous in time right now and we've pretty much squeezed the spreads to their maximum, so while prices aren't continuous they are about as close as we can get w/o eliminating the profitability of the primary market participant (market makers) that make it function.

You can scheme up any number of possible microstructures that sound interesting on the surface. There's a reason why none exist. Remember, there is nothing to stop you from implementing a time-discretized market place. Current regulations (Reg-ATS) allow for you to do so. You'll find it hard to compete. Some markets do perform large scale discretization for block orders. Read up on POSIT and related ATSs and dark pools.

It looks like MPL orders are undisplayed. Then how can they "display at a price but execute at a separate price"? Or, what does it mean when I read "The MPL order is an undisplayed limit order that is priced at the midpoint of the Protected Best Bid and Offer (PBBO)" if it doesn't actually mean undisplayed.

edit: ah the above edit helps. thanks.
My basketball coach once said that a team that spends 12 hours each day practicing will lose the championship to a team that only has one hour of practice a day. "We all love this sport", he said, "and we could all practice all day long, which is fine, but if you want to win the championship, you have to be smart and pace yourself". To me, this lesson applies to any organisation that values long term results.
In my opinion, I'd say the main difference is that Clojure tends to be a box of many tools that have very specific functionality, while Javascript tends to have fewer tools with very generic functionality.

For instance, in Javascript an object is a way of storing values, defining an identity (i.e. a mutable pointer to a value), namespacing, polymorphism and inheritance.

In Clojure, each piece of functionality is handled by a different tool. If you just want a value you can use an immutable map. If you want a changeable identity you might use an atom. Polymorphism is provided by protocols or multimethods, namespacing by namespaces and so forth.

The advantage of using discrete tools is that you can afford to specialise. Clojure has atoms, refs and agents for maintaining identity, and each has unique properties. Libraries (such as Avout) can extend this with their own systems for maintaining identity.

Javascript, along with many OOP languages, has the problem that objects are a jack of all trades, but a master of none. An object cannot handle atomic state change as well as an atom, nor handle polymorphism as well as a protocol, nor is it a good at namespacing as a Clojure namespace. By being so general-use, it can't be as good as tools that focus on doing one job.

LocomotiveCMS Approaches 2.0 Release
You said a lot with very few words. There are entrepreneurs and what people think an entrepreneur is. Most people do want to be entrepreneurs except they want to be the second, unrealistic kind. You know, the kind that makes their own hours, works in their pajamas, does a lot of delegating but not much real work, and takes a lot of vacations on Yachts in the Pacific. People want to do that. Everyone wants to do that.

Too bad most who try will find out that real entrepreneurship isn't all Yachts, caviar, and a totally flexible schedule. It's harder than being an employee, especially at first.
Both Eric Ries and Steve Blank are actual entrepreneurs who have tried on multiple occasions and have both success and failure in their experience.

Eric Ries founded CatalystRecruiting as an undergrad, worked as an engineer for a few years, and then co-founded and was CTO of IMVU, which had a string of internal failures followed by perseverance and success. His experience there seems to have formed the core of the Lean Startup book.

Straight from Steven Blank's personal bio: "After 21 years in 8 high technology companies, I retired in 1999. I co-founded my last company, E.piphany, in my living room in 1996. My other startups include two semiconductor companies, Zilog and MIPS Computers, a workstation company Convergent Technologies, a consulting stint for a graphics hardware/software spinout Pixar, a supercomputer firm, Ardent, a computer peripheral supplier, SuperMac, a military intelligence systems supplier, ESL and a video game company, Rocket Science Games.
Total score: two large craters (Rocket Science and Ardent), one dot.com bubble home run (E.piphany) and several base hits."

Don't write somebody off as an academic just because they've written a book.
The very first two lines of the article:

"Today I want to talk about a script that appeared in a post on Mac OS X Hints a couple of days ago. What the script does isn’t of great interest to me, but the technique the programmer used to combine Python and AppleScript is."
I agree that entrepreneurship is challenging, but I think the tone of this article is bunk.

We should absolutely be brutal and frank in our questioning. That's because the world will be even tougher on their ideas once they start taking action. They need to be ready for that, and they will benefit by thinking things through a bit.

But we should never pour cold water on people's enthusiasm. We should never tell people their idea won't work. We should never butt in to tell them how they should be spending their time.

Enthusiasm is precious, and none of us has a crystal ball. Making mistakes is an important part of life. By all means we should help people avoid dumb mistakes, but only because we want them to be making interesting ones.

What say the musicians? What are their pain points? And really focus on disruptive, as that is where the ripest of opportunities remain.

Just don't try to be the ______ (Craigslist/Facebook/Pinterest/HotOrNot) for musicians because _____ is probably sufficient, if not better for the simple reason that it's already being utilized and substitution is unlikely to be the droid that you are looking for.

Though I'm not a musician myself, you've really piqued my interest and I'm going to go poll my surprisingly large collection of musician friends and acquaintances...

Contributing to open source projects, attending user groups in my spare time, and mostly reading books about coding and productivity do NOT mean that I allow my employment to penetrate deeply into my personal life. I allow my interests and my passions to penetrate deeply into my personal life. If you don't have the good fortune to be paid for your passions, don't put down those who do as corporate shills.

I also make plenty of time for family and fun. Maybe it's all of those productivity books.
If you were writing this in C, you'd return a point as a struct. The Java equivalent of a struct is a class. Write a class to wrap those values and return an instance of that class. Yes, there's overhead there that a struct strictly avoids, but it's the way the language was designed, and it's a much better solution than indexing into an array or collection.

As for multiple return, I've never once seen a need for it that couldn't be solved by creating ad-hoc MethodReturnValue classes that wrapped everything I wanted to return multiply.

It would be nice for a box to pop up if the key is not detected in the hash, asking for the decryption key (and password if that's set).

That way, you enable two types of users:

* The "I just don't want the server to have this stored in plaintext" type.

* The "I'll send you the URL now and the key via some secure channel" type.

Also, if you browse incognito, then there shouldn't be a browser history containing the keys.

Here's the problem with Hulu's guarantee.

Sure the ad plays all the way to the end when I'm watching a video. Thats because it has to in order for me to watch the rest of my show. I'm already invested so unless I have to leave I'm going to let those ads run through. But I don't watch the whole thing. Most of the time I don't watch it at all. I hit the mute button and check something else for that minute and a half. It's the same as fast forwarding on the DVR except you still have to wait till the end of the ad. Sure Hulu makes money from the ad showing, but the advertiser gets nothing in return, the ad ran but I didn't watch it.

I would have loved it if they used a larger sensor. However not like canon dslr but more like sony FS100. Canon 5d2/3 have a problem reducing all these pixels down to HD. And it's not the sensor size but pixel pitch that impacts S/N ratio. At 2.5K I think this camera has a better pixel density than the canon5d2/3.

The biggest issue is DOF. Which will require fast lenses at shorter focal length that don't readily exist yet.

I would argue the Kama Sutra is both historical and educational and not sexually explicit at all.

What does "sexual explicit" mean? It is quite explicit about sex -- it is wholly concerned with sex.

However the app in question is not the historic Kama Sutra. It is a list of sexual positions, and by their own admission, with some subtle between the lines commentary, they seemed to be pushing boundaries on what graphically was allowed.
