Auto-writing Software Good software writes itself. We all know the patterns and following them makes things easy. Not because we have memorized any monumental volume on design patterns, but because years of experience taught us what should be done on an almost intuitive level. Also in a negative sense. We avoid duplication, globals, encapsulation violations. […]

Much of Scala’s power comes from its flexibility and generality as a language. You can mold it quite extensively to suit your particular problem domain or coding style. The downside of this is that Scala can sometimes be permissive and accommodating to a fault. You often hear Haskell or F# users attest to a sense of “if it compiles, it works” – in my experience this is not generally the case with Scala. To illustrate this point, let’s walk through a few examples, all of which are distilled from honest-[...]

The Choices I have experimented with OpenCV and Dlib face detection in my computer vision pipeline. Both work well, but the Dlib one worked better: it is more sensitive with (in my case) almost no false positives right out of the box! Dlib uses several HOG filters that account for profile as well as frontal […]

The post on applying GPU to finding Eulerian path mentioned a stumbling block: partitioning a very specific kind of graph. In general, partitioning is a hard problem, NP-hard actually. The graphs we are dealing with are very specific, though, and may be partitioned in time (E – the set of graph edges). Our graphs are […]

A LONG TIME AGO, IN A GALAXY FAR AWAY….. Having infiltrated the Empire’s data centre, you are not overly surprised to discover they are using some ancient system from the old republic days.  A brief look around reveals a monstrous legacy Empire Enterprise system.  It has a ORM you thought had died out millennia ago.  You can immediately see no less than 13 layers of inheritance, 6 levels of dependency injection, and some complete bastard has spread the evil EmpireAutoLogger all over the place Thankfull[...]
