[1104.5466] Notes on a New Philosophy of Empirical Science
This book presents a methodology and philosophy of empirical science based on large scale lossless data compression. In this view a theory is scientific if it can be used to build a data compression program, and it is valuable if it can compress a standard benchmark database to a small size, taking into account the length of the compressor itself. This methodology therefore includes an Occam principle as well as a solution to the problem of demarcation. Because of the fundamental difficulty of lossless compression, this type of research must be empirical in nature: compression can only be achieved by discovering and characterizing empirical regularities in the data. Because of this, the philosophy provides a way to reformulate fields such as computer vision and computational linguistics as empirical sciences: the former by attempting to compress databases of natural images, the latter by attempting to compress large text databases. The book argues that the rigor and objectivity of the compression principle should set the stage for systematic progress in these fields. The argument is especially strong in the context of computer vision, which is plagued by chronic problems of evaluation.
The book also considers the field of machine learning. Here the traditional approach requires that the models proposed to solve learning problems be extremely simple, in order to avoid overfitting. However, the world may contain intrinsically complex phenomena, which would require complex models to understand. The compression philosophy can justify complex models because of the large quantity of data being modeled (if the target database is 100 Gb, it is easy to justify a 10 Mb model). The complex models and abstractions learned on the basis of the raw data (images, language, etc) can then be reused to solve any specific learning problem, such as face recognition or machine translation.

A Guide to Website Image Optimization and Performance
The RICG had a few goals, some shouted from the rooftops and some not. For example, the goal of finding efficient, preparser-friendly methods of tailoring image requests to browsing contexts was no secret. Paving a path for more designers and developers to become involved in the standards process—we were pretty loud about that one, too. More subtle, however, was a goal many RICG members shared, me included: a day when we would hardly think about responsive images.

Building for sustainability with WordPress - Susty WP
The web has a dirty secret – it uses a lot of electricity. The Internet's carbon footprint has possibly already surpassed that of global air travel. Susty WP is a collection of resources and best practices, as well as being a practical example itself, for how WordPress developers can make the web more sustainable.
