    Static analysis of a code in a graph database

    GREENSPECTOR is a tool detecting software’s behaviors which have an impact on resources consumption (energy, memory…). In order to do that, we use a set of techniques allowing the developer to be furthermore precise in its observations, thus leading to greater gains with fewer efforts. Code analysis and recognition of consuming patterns are part of these techniques. Most of the time, code analysis is mainly focused on a syntactic recognition (as we can see in an IDE – Interface Development Environment – whenever we code and the IDE offers another type of writing).

    WebP, PNG, JPEG : Energy battle on Android

    Webp is the new image format offered by Google, who promises a reduction between 30 and 80% in transfer size. In addition, this format would be more suitable for current processors. But what should we expect in terms of energy consumption on the user’s device? Webp format Webp is a matrix format just like PNG or JPEG. It can handle lossless compressions like PNG, as well as lossy ones like JPEG.
