In my last couple of posts I talked about how much of your (autosomal) genome you inherit from a particular ancestor [1,2]. In the chart below I show a family tree radiating out from one individual. Each successive layer out shows an individual’s ancestors another generation back in time, parents, grandparents, great-grandparents and so on back (red for female, blue for male). Each generation back
First, let me say what you read here is going to be wrong in several ways. HFT covers such a wide path of trading that different parties participate or are impacted in different ways. I wanted to put this out there as a starting point . Hopefully the comments will help further educate us all 1. Electronic trading is part of HFT, but not all electronic trading is high frequency trading. Trading e
Haskell design patterns differ from mainstream design patterns in one important way: Conventional architecture: Combine a several components together of type A to generate a "network" or "topology" of type B Haskell architecture: Combine several components together of type A to generate a new component of the same type A, indistinguishable in character from its substituent parts This distinction a

Network monitoring on Linux This post mentions some linux command line tools that can be used to monitor the network usage. These tools monitor the traffic flowing through network interfaces and measure the speed at which data is currently being transferred. Incoming and outgoing traffic is shown separately. Some of the commands, show the bandwidth used by individual processes. This makes it easy
In 2013, a consortium of the greatest mathematicians published a massive volume which reboots our conception of mathematics. Plus, in April 2014, Carnegie Mellon has received 7.5 million dollars from the Department of Defense to write the sequels of that book. In this article, we’ll dig into a new structure they’ve defined, which seems like a revolutionary and liberating breakthrough to me. This s

Last week I gave a (poorly prepared) talk outlining how the Rust compiler works internally. Though the slides might be helpful & there was some interesting discussion after the talk, I thought a full post might do this topic more justice. Note that as of writing this the current release of Rust is 0.10. Some of what I cover in this article may well change by the time you get around to reading this
A new version of Idris, 0.9.12, has been released. You can find this on hackage, or from the download page. The tutorial has also been updated. There are some changes in this release which may break old code, specifically laziness, codata and the effects library have been significantly updated. Full details are in the new tutorial, and in the Effects tutorial. Thanks as always to everyone who has

The Galaxy Zoo challenge on Kaggle has just finished. The goal of the competition was to predict how Galaxy Zoo users (zooites) would classify images of galaxies from the Sloan Digital Sky Survey. I finished in 1st place and in this post I’m going to explain how my solution works. Introduction The problem Galaxy Zoo is a crowdsourcing project, where users are asked to describe the morphology of ga

Recent versions of JavaScript engines are designed to execute large bodies of code very fast but if you don't know how JavaScript engines work internally you could easily degrade your application's performance. It's specially true for games that need every drop of performance they can get. In this article I will try to explain some common optimization methods for JavaScript code that I picked up d
Build Your Own Lisp Learn C and build your own programming language in 1000 lines of code! If you're looking to learn C, or you've ever wondered how to build your own programming language, this is the book for you. In just a few lines of code, I'll teach you how to use C, and together, we'll start building your very own language. Along the way we'll learn about the weird and wonderful nature of Li
Things that amuse me: Haskell error reporting with locations
Error reporting in GHC is not always the nicest. For example, I often develop code by using undefined as a placeholder for code I've not written yet. Here's a simple example: import System.Environment main = do args <- getargs if null args then undefined else undefined Running this looks like this: $ ./H H: Prelude.undefined Which undefined caused that? Looking at the error message we have no idea
Introducing Pyston: an upcoming, JIT-based Python implementation Hello everyone, I’m very excited to announce Pyston, a new open-source implementation of Python, currently under development at Dropbox. The goal of the project is to produce a high-performance Python implementation that can push Python into domains dominated by traditional systems languages like C++. Here at Dropbox, we love Python
