Generalized linear models (GLMs) are indispensable tools in the data science toolbox. They are applicable to many real-world problems involving continuous, yes/no, count and survival data (and more). The models themselves are intuitive and can be used for inference and prediction. A few very high quality free and open…
World of Warcraft: one simple line of code can cost you dearly
A few days ago, a new type of gold/item scam made the rounds. Usually scamming in MMORPGs is done using social engineering techniques, e.g. an attacker sells a fake item code for alleged in-game items like mounts to a potential victim for in-game currency.

Space Emerging from Quantum Mechanics
The other day I was amused to find a quote from Einstein , in 1936, about how hard it would be to quantize gravity: “like an attempt to breathe in empty space.” Eight decades later, I think we can still agree that it’s hard.
Hard Forks
The crypto-currency Ethereum completed a hard fork on Wednesday. The Ethereum core developers, after getting a vote of support from the Ethereum community, hard forked Ethereum to “get back” the roughly $40mm of Ethereum that was taken in the hack of The DAO. Hard forks are a bit of a lightning rod issue in the […]
