IA Frugale : de l’ambition d’un référentiel à la réalité du marché
Alors qu’un premier référentiel sur l’Intelligence Artificielle (IA) frugale est paru en juin 2024, il reste désormais un enjeu à en faire adopter massivement les principes. Mais d’ailleurs peut-on réellement parler de frugalité face à une technologie adoptée à la hâte par le plus grand nombre et qui n’a de cesse de faire grimper l’empreinte environnementale du numérique au sein des entreprises ? Pour l’heure aucune réponse évidente n’émerge. […]
Sobriété numérique : comment lever les verrous ?
Aller vers une forme de sobriété numérique est un chemin pavé d’embûches tant les obstacles sont nombreux. Qu’ils soient d’ordres techniques, culturels, politiques, psychologiques ou encore économiques, ils entravent fortement le passage à la sobriété. Néanmoins, quelques lueurs d’espoirs existent ici et là pour faire effet de levier. […]

Climate change implications of gaming products and services - University of Surrey
There is increasing concern over the climate change impact of games consoles. There is, however, little research on the life cycle carbon impact of consoles and existing research (the majority of which is focused on usage) is outdated. This study uses life cycle assessment (LCA) methodology to compare the climate change impact of different console-based gaming methods (i.e. games played from a disc, a down-loaded file, or streamed from the cloud). Console usage and Internet usage were identified as life cycle stages where data were unknown or uncertain. Two studies to improve the understanding of these areas were undertaken in this research and used to complete a cradle-to-grave carbon footprint study of gaming (compared using a functional unit of carbon equivalent emissions per hour of gameplay). Results estimated that, for average cases, download is the lowest carbon method of gaming at 0.047 kgCO2e/h, followed by disc at 0.055 kgCO2e/h. Cloud gaming has higher estimated carbon emissions at 0.149 kgCO2e/h, largely due to the additional energy consumed during use in the Internet, gaming servers, and home router equip-ment. These findings only represent average cases and the size of game files and length of gameplay time were found to be key variables significantly impacting the results. For example, for games played for under 8 hours, cloud gaming was found to have lower carbon emissions than downloads (up to 24 hours when compared to disc). In order to analyse these results, a new method for identifying which gaming method has the lowest carbon emissions with variation in both file size and gameplay time was developed. This has allowed for the identification of the thresholds in which different gaming methods have lowest carbon emissions, for any given range of input variables. The carbon emissions of gaming are highly dependent on consumer behav-iour (which game method is used, how long games are played for, and the type and size of those games) and therefore LCA based on average assumptions for these variables has limited application.
Choosing Between gzip, Brotli and zStandard Compression
HTTP compression is a mechanism that allows a web server to deliver text based content using less bytes, and it’s been supported on the web for a very long time. In fact the first web browser to support gzip compression was NCSA Mosaic v2.1 way back in 1993! The web has obviously come a long way since then, but today pretty much every web server and browser still supports gzip compression.
Discovering Third Party Performance Risks
It likely comes as no surprise that third party content can be a significant contributor to slow loading websites and poor user experience. As performance engineers, we often need to find ways to balance requirements for their features with the strain that they can put on user experience. Unfortunately, for many sites this becomes a reaction to slowdowns and failures detected in production.
