Master of Science / Department of Computer Science / Mitchell L. Neilsen / Mobile technology has advanced significantly in the last decade, devices have gotten smaller and much more powerful. Because mobile devices are so accessible, they have spread everywhere and are used extensively by an immense portion of the population for various tasks. Mobile devices are no longer a means to just communicate with another person, you can use them to take pictures, scan documents, create a Wi-Fi hotspot, or just be entertained. E-Readers have been around for a while and implemented as a source of entertainment on many mobile platforms. However very few e-readers for Manga, which is a type of comic book, have been developed. Manga Feed, built on the Android platform, strives to help fill this void by providing a clean and simple to user interface for users to enjoy reading on the go. There are thousands of manga of various genres made available to users, offering entertainment to any individual interested in manga.

La dernière génération de cartes à puce permet le téléchargement d'applications après leur mise en circulation. Outre les problèmes de sécurité que cela implique, cette capacité d'extension applicative reste encore aujourd'hui bridée par un espace de stockage adressable restreint. La thèse défendue dans ce mémoire est qu'il est possible d'exécuter efficacement des applications stockées dans la mémoire non-adressable des cartes à puce, disponible en plus grande quantité, et ce, malgré ses temps de latences très longs, donc peu favorables a priori à l'exécution de code. Notre travail consiste d'abord à étudier les forces et faiblesses de la principale réponse proposée par l'état de l'art qu'est un cache. Cependant, dans notre contexte, il ne peut être implémenté qu'en logiciel, avec alors une latence supplémentaire. De plus, ce cache doit respecter les contraintes mémoires des cartes à puce et doit donc avoir une empreinte mémoire faible. Nous montrons comment et pourquoi ces deux contraintes réduisent fortement les performances d'un cache, qui devient alors une réponse insuffisante pour la résolution de notre challenge. Nous appliquons notre démonstration aux caches de code natif, puis de code et méta-données Java et JavaCard2. Fort de ces constats, nous proposons puis validons une solution reposant sur une pré-interprétation de code, dont le but est à la fois de détecter précocement les données manquantes en cache pour les charger à l'avance et en parallèle, mais aussi grouper des accès au cache et réduire ainsi l'impact de son temps de latence logiciel, démontré comme son principal coût. Le tout produit alors une solution efficace, passant l'échelle des cartes à puce. / The latest generation of smart cards allows to download applications after they are released. In addition to new security issues, this ability still remains constrained by a limited addressable storage space. The claim of our thesis is that it is possible to efficiently execute applications stored in the non-addressable memory of smart cards, available in larger quantities, and, despite its very long latency. Our work is first a study of the strengths and weaknesses of the main solution provided by the state of the art : caching. However, in our context, it can be implemented only in software,then with an additional latency. In addition, the cache must comply with memory constraints of smart cards and must then have on a low memory footprint. We show how and why these two constraints greatly reduce the performance of a cache, that finally becomes inadequate to fully tackle our challenge. We apply our demonstration to native instructions caches, then to Java/JavaCard2 instructions and metadata caches. Based on our observations, we propose and validate a solution based on a code pre-interpretation, whose purpose is to early detect of missing data in the cache to fetch them in advance, then to group accesses to the cache in order to reduce the impact of its software latency, that we demonstrate to be its main cost. Our result is an effective solution, that fits smart cards size and constraints.

The subject of this thesis is an analysis of plugin technology. The goal of the thesis is to characterization of basics of this technology in common and with focus on application on NetBeans platform and its integrated development environment and further demonstration of the technology in form developing exemplary NetBeans plugin. Opening part is dedicated to theoretical analysis of plugin principals, its purposes in soft-ware development and use cases for current software applications. The theoretical part follows by describing use cases of plugins for NetBeans platform and bringing thought for designing, developing and distributing new plugins. The subsequent part is dedicated to implementation of NetBeans plugin to demonstrate technology and methods described. The result of implementation is a NetBeans plugin allowing advanced editing of documentation commentary from Java source code inside WYSISYG HTML editor just from NetBeans environment. The resulting plugin, source codes and documentation is included attachment of this thesis. This thesis expands collection of theses dedicated to subject of NetBeans platform and those theses are referred in the text.
