Resource Management: xcres

We tend to keep our resource references pretty much in order by reflex when writing them actually, but looks like this might make that more streamlined. And looks like it would be downright invaluable the next time we’re handed some mess to make sense of written by someone who regarded the concept of ‘maintainability’ with fear and loathing apparently…

Checking in binaries

When Maven came out some twelve years ago, the Java community became comfortable with not checking in third-party binaries. In the Ant era, before that, you did. Maybe we were being kind to source control systems, but we opened a new can of worms.

Scipy.optimization.anneal Problems

I'm not even certain that I could help them with some of the Python technology required to extend scipy. But, I'm sure I cannot actually do anything of value under the circumstances that (a) they have not really tried the established algorithms and (b) they're already sure that the established algorithms can't work based on religious-wars arguments.

TL;DR: The realities of modern corporate networks make the move to distributed database architectures inevitable. How do you leverage the stability and security of traditional relational database designs while making the transition to distributed environments? One key consideration is to ensure your cloud databases are scalable enough to deliver the technology's cost and performance benefits.

Cross Validation for Kernel Density Estimation

In a post published in July, I mentioned the so-called Goldilocks principle, in the context of kernel density estimation, and bandwidth selection. The bandwidth should not be too small (the variance would be too large) and it should not be too large (the bias would be too large).
