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.

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.

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(

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 annualize

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

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 tr

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 bec

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

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?

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
