• Detecting bootable IBM Power server ISO images (IBM Developerworks)
  Most ISO images use an ISO 9660 extension that allows the image to be bootable by the basic input/output system (BIOS). IBM Power Systems firmware, on the other hand, does not use such extension. This means that the detection of the bootability of images differ between computer architectures. In software such as hypervisors or even virtual machine (VM) managers, this detection can't consume too many resources and take too much time due to the number of the images they need to manipulate. This makes options like such as trying to boot the image by trial and error or even trying to mount the image in the file system not viable. This article describes a way to detect if an IBM Power server image is bootable by reading the ISO data stream directly, showing a working Python code that illustrates the concepts.
• Inqlude recense 184 bibliothèques dans l'écosystème Qt et donne un bon aperçu de l'étendue des extensions développées (Développez.com)
  Après trois années de développement, l'idée d'Inqlude, soit un dépôt de bibliothèques, un gestionnaire de paquets centré sur Qt, arrive à un certain niveau de maturité : l'auteur considère le projet comme prêt pour les utilisateurs précoces. Notamment, l'outil est utilisé pour générer le site Web inqlude.org ; parmi les bibliothèques présentes, un grand nombre provient des KDE Frameworks 5. À terme, il se veut l'équivalent de Bower ou npm en JavaScript, de RubyGems ou encore de pip pour Python.
