Today, at devLink 2014, my last session of the day is “Practical Machine Learning – Predicting Things” by Seth Juarez. In his presentation, Seth talks about machine learning and his machine learning library, numl. The session is very entertaining and I learn a lot from it. Fun fact: Seth originally called his library, Machine Learning … Continue reading →

My recollection of how this all started is somewhat fuzzy at that point. I remember talking to @tomaspetricek about the recent “A pleasant round of golf” with @relentlessdev event in London. The idea of Code Golf is to write code that fits in as few characters as possible – a terrible idea in most cases, but an interesting one if you want to force your brain into unknown territory. Also, a very fun idea, with lots of possibilities. If I recall correctly, the discussion soon drifted to the conclusion that i[...]

Compute the mathces Here is a simple, purely brute-force algorithm for computing the join mentioned in Part 1. Here is the entirely “CPU” implementation of the algorithm: Loop over both datasets, compare them one-by-one, if there is a match – flag it. The only thing to note is that while it’s tempting to write the […]

This is a post in two parts: Part 1 – The problem, solution setup, the algorithm. Part 2 – (The juicy) Implementation details, discussion. Suppose at the heart of the data layer of a web application there is a join like this: This join filters patents belonging to a set of classes from the Patents […]

Just a quick note. If you are starting from a template C++ CUDA project in VS 2012/2013, calling a kernel from a kernel (dynamic parallelism) would not compile: error : kernel launch from __device__ or __global__ functions requires separate compilation mode To fix this, first make sure your hardware supports it (cc 3.5 or higher) […]
