Lots of debate here about the best model. The best model is the one which creates the most value for you —- this typically is a function of your skill in using the model for tasks that matter to you. Always was. Always will be.

Quantitative trading, hedge fund, New York, NY, ONSITE

I run a systematic quant trading group that trades globally. We are research driven and are working on solving tough problems at the intersection of math, statistics, and computer science. We believe that the combination of a rigorous scientific approach with solid engineering can expose inefficiencies in the markets.

We are looking for engineers/data scientists who have experience building mission critical distributed systems or large scale data pipelines.

Please get in touch (hiring.quant.trading AT gmail) if any of these things are applicable to you:

* You understand or have worked with applied math or computer science at an advanced level

* You have serious engineering chops and have built large scale high performance systems

* You are fluent in one or more of (c, java, golang, rust) and (python, q)

* You enjoy working in small groups in a fast paced environment

* You have experience building order management and execution systems for trading

* You enjoy working with data

We value the following personality traits:

* Intellectual curiosity

* Good work ethic

* Self-motivation

This is an exceptional opportunity for the right person. There is tremendous potential for both growth and comp, but it is not going to be a smooth ride. Our goal is to build something exceptional and the right person is used to not making choices that are “easy” or “default”.

Well said. If you have or build an "edge" over time the distribution of your outcomes will have a positive mean. Along the way you may see values on the tails which are random spikes.

Quantitative trading, hedge fund, New York, NY, ONSITE

I am starting a new quantitative trading group that will systematically trade global Futures, FX, and Equities. We are research driven and are working on solving some really tough problems at the intersection of math, statistics, and computer science. We believe that the combination of a rigorous scientific approach with solid engineering can expose inefficiencies in the markets.

We are looking for people who are self-motivated, entrepreneurial, love working with data, and more importantly have the ability to go both broad and deep into problems.

Please get in touch (hiring.quant.trading AT gmail) if any of these things are applicable to you:

* You understand or have worked with applied math, statistics, or computer science at an advanced level

* You know mathematical optimization and can write your own convex solver if needed

* You have experience applying machine learning/statistics to noisy data

* You have serious engineering chops and have built large scale high performance systems

* You are fluent in one or more languages (python, c, java, q, R)

* You enjoy working in small groups in a fast paced environment

In additional to really interesting work, we offer tremendous potential for growth and compensation.

Agree about the cost. However, I would think that a wider adoption would eventually bring the cost down and perhaps even spawn a bunch of related open-source projects.

As far as readability is concerned, q(KDB+) is far more readable than k(KDB). Also, nobody stops you from adopting a coding style that is more readable. That is what I personally do.

Well, all you need to do is to look at KDB+ from kx.

All the other products that you mention are for children ;)

Can somebody comment on the advantages of using this over zeromq/nanomsg?

Thanks!

We used them recently in nyc and user experience was great. However once you do the math, a 10 - 15% markup on most products in addition to delivery fees, tips, (or prime) is simply too much if you use them on a regular basis. The annualized cost for a small family is easily north of $2000.

Now I know that "price is what you pay and value is what you get". So there are definitely occasions when I will use them. But I honestly doubt that most of their users realize the true cost of their service.

I did not realize that the email is not publicly displayed. I have put in the about section now.

Hey, I wanted to send you a message but your profile has no email. Can you send me a message or put an email in your profile? Thanks.

I have a travel startup that is meant to solve the planning problem in a different way, but I agree with Gary. We painfully learned that -

a) We created an elegant solution to free. That is always a bad idea

b) User acquisition is extremely hard without spending tons of money

c) Even though the users love the product, the fact that they would only use it couple of times a year means that you need to have lots of users, which circles back to the previous point

It sucks because the travel space really needs quality apps and I would like to believe that there is a way around all the issues for startups. But the fact remains that it is a bad idea for most people.

Excellent analysis. I am sick of seeing these Nanex posts(rants); the lack a basic familiarity of market microstructure mechanisms.

The market maker is not sitting there to let you run him over and thank you for it.

As a price taker, the trader has to incur slippage due to the market impact of his large order.

Thanks. That is sort of like going to war with knives amongst machine guns, but what do I know.

A question for DDG or anyone who might know: How does DDG plan to monetize this without storing any data?

Well, the reality is that the top ~5% of hedge funds generate all the returns and have real alpha. The rest are beta + noise - transaction costs.

Not dissimilar to the way venture returns are distributed. Only the top startups manage to become big companies and provide a sizable return to their investors.

So hedge funds get away with it the same way most startups get away with it. For better or for worse, the investors do not have the ability to accurately discriminate.

This would actually make a terrific replacement for something like redis when you need a more structured schema.

The q language is very powerful, and expressive - interesting mix of lisp and APL. You can do really powerful analytics without writing tons of code for it.

You really have to see how fast KDB is compared to most nosql products out there.

Does anyone know if these scores have been predictive of success in the past?

This is really great advice. One other thing that has helped me immensely is getting a dog! It automatically forces you to take breaks.

"But in fact the main thing driving Airbnb's growth is not price, but that guests are looking for authentic experiences"

Do you think that as the services that Airbnb provides gets more standardized, the Airbnb experience will inevitably get more transactional like traditional hotels?

If so, do you think that their core user base is likely to shift towards more traditional traveler?

Let me pile on the offer. Along with drinks, I can help you analyze your data or advice you on your technology stack.

Thanks for the great advice. We would love to have you look at our application ;)

Thanks. Good advice on getting intros.

Couple of questions for the original poster -

1) Were you already profitable or had revenues when you started fundraising?

2) How did you manage to get intros to Angels?

I see. Any pointers to a cheap payroll processing company?

A naive question to founders who have taken such seed funding before - can you directly take money out of a investment like this to pay for your living costs or you have to go through the headache of establishing payroll and a small salary for the founders?

Thanks for the clarification. Thats what I thought. So convertible note is much better for the entrepreneur. It retains the optionality of doing well and consequently giving out less equity.

Thanks for explaining. These deals are such an opaque market that first time entrepreneurs have no idea what is good and what is bad.

I thought the convertible note is to be converted to equity in series A. If the company did well, it would presumably have a higher valuation, and they would have to give away far less than 25%.
