OpenFace - Face Recognition For All

Face recognition, once the preserve of the few, the likes of intelligence and security services, is now made available to the masses as well, thanks to OpenFace.

Caveat, there are many face detection libraries, such as OpenCV, and applications like Facebook or Picasa, but this is about face recognition, and applications of this kind are not easily found in public.

OpenFace changes all that. It is an open source face recognition implementation, written in Python and Torch, and based on deep learning and neural networks . As such, it relies on a number of components that work together as pipelines, each one basing its input on the previous component's output. These are dlib and OpenVC, used for the face detection, alignment and transformation; the Torch machine learning library for implementing deep learning; and nn4, the neural network model itself.

Since then the scene has changed a lot, with many alternative options challenging the monopoly established by Github. However, its pre-eminent position allowed Github to more or less take for granted that every open source project out there would use it as its hosting service.

Advanced Perl Regular Expressions - Extended Constructs

Perl is still the leader, almost the standard, when it comes to regular expressions. However it also possesses some lesser known features that  deserve special attention, like the embedded code constructs for runtime code evaluation. Let's find out what Perl regular expressions are really like with Perl inside.

How does Perl let you mix code and regular expressions?
It provides the (?{ code }) construct which essentially allows for embedding Perl code that gets executed upon every match of the pattern, inside the regular expression.
For example, let's say we have a file that is about to be distributed to multiple platforms/Operating Systems therefore its file name needs to be portable and compatible with the various OSs' file systems. What is the best way to achieve this?
