Notes The data is access log of mirrors.ustc.edu.cn in 51 days. See ‘Technical Details’ section for more info about dataset. Some graphs are in log-scale for clarity. Please note whether x axis, y axis or both are in log-scale. The graph title sometimes lies. Because there may be many points in a graph, sampling is made to reduce file size (they are vector graphics), hence there may be some ‘straight lines’. I have checked the data to make sure the graphs illustrate real trends. Title length is limited, so the title itself may not explain well, please keep an eye on the axis and keys of the graph. Graphs are shown in the hope of conveying information without words. Any questions or suggestions, please email me. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. 李博杰 [email protected] Visualizing Mirrors .

Its objective was to create an automation tool that would free the Product Assurance team at Critical Software, S.A. from repetitive and time-consuming tasks, while at the same time providing a platform upon which further systems could be implemented, augmenting the tool kit of the Product Assurance Engineers. This was achieved by designing a modular and extensible platform using cutting-edge Java technologies, and following a goal-oriented development process that focused on iteratively providing as many domain-specific features as possible. It is shown that the resulting system has the potential for considerably reducing costs in the validation of projects throughout their entire life cycle. i ii Resumo Este relatório descreve a motivação, arquitectura e o retorno sobre o investimento após a implementação de uma solução para a Validação e Reporting On-Process. O seu objec- tivo era a criação de uma ferramenta de automação que libertaria a equipa de Controlo de Produto da Critical Software, S.A.

  • Eclipse Roadmap V5
    Eclipse RoadMap v5 Introduction As required by the Eclipse Development Process, this document describes the 2010 Eclipse Roadmap. There are three main sections to this document: 1. This Preamble provides some background on Eclipse and the Foundation, and identifies the strategic goals of Eclipse. It also provides a brief overview of the scope of future projects 2. The Themes and Priorities which has been developed by the Eclipse Councils. 3. The Platform Release Plan which has been developed by the Eclipse Planning Council. The Roadmap is intended to be a living document which will see future iterations. This document is the fifth version of the Eclipse Roadmap, and is labeled as version 5.0. In order to preserve this document while the underlying information evolves, the pages have been frozen by copying them from their original project hosted locations. The goal of the Roadmap is to provide the Eclipse ecosystem with guidance and visibility on the future directions of the Eclipse open source community. An important element in this visibility is that the Roadmap help the EMO and the Board of Directors in determining which projects will be accepted by Eclipse during the life of this revision of the Roadmap. In other words, new projects must be consistent with the Roadmap. This does not mean that every new project must be explicitly envisaged by the Roadmap. It does mean that new projects cannot be inconsistent with the stated directions of Eclipse. In particular, Eclipse expects that incubator projects created in the Technology PMC will cover areas not explicitly described in the Roadmap.

  • Das Ende Der Finsternis Markus Karg, Java User Group Pforzheim
    Das Ende der Finsternis Markus Karg, Java User Group Pforzheim Nachdem die Anwenderschaft, neudeutsch „Community“, monatelang lautstark an der offensichtlichen Untätigkeit von Oracle herumgemeckert hat, ging es plötzlich ganz schnell: Java EE wurde an die Eclipse Foundation übergeben. Doch was bedeutet das im Detail? Ist Java EE nun tot und die JCP aufgelöst? Ein bewusst provokativer Kommentar aus Anwendersicht. Plötzlich war es da: das lange geforderte Öffnen von Test Compatibility ge Java EE) dort weiterentwickelt werde. Aber werden sie das denn Kits (TCK), Reference Implementations (RI) und Specifications (Specs). wirklich?

  • SDN Ro2tkits: a Case Study of Subverting a Closed Source SDN Controller
    H. Langweg,H. Langweg, M. Meier, M. Meier, B.C. B.C. Witt, Witt, D. Reinhardt D. Reinhardt et al. (Hrsg.): Sicherheit 2018, LectureLecture Notes Notes in in Informatics Informatics (LNI), (LNI), Gesellschaft Gesellschaft für für Informatik, Informatik, Bonn Bonn 2018 2018 7995 SDN Ro2tkits: A Case Study of Subverting A Closed Source SDN Controller Christian Röpke1 Abstract: An SDN controller is a core component of the SDN architecture. It is responsible for managing an underlying network while allowing SDN applications to program it as required. Because of this central role, compromising such an SDN controller is of high interest for an attacker. A recently published SDN rootkit has demonstrated, for example, that a malicious SDN application is able to manipulate an entire network while hiding corresponding malicious actions. However, the facts that this attack targeted an open source SDN controller and applied a specific way to subvert this system leaves important questions unanswered: How easy is it to attack closed source SDN controllers in the same way? Can we concentrate on the already presented technique or do we need to consider other attack vectors as well to protect SDN controllers? In this paper, we elaborate on these research questions and present two new SDN rootkits, both targeting a closed source SDN controller. Similar to previous work, the first one is based on Java reflection. In contrast to known reflection abuses, however, we must develop new techniques asthe existing ones can only be adopted in parts. Additionally, we demonstrate by a second SDN rootkit that an attacker is by no means limited to reflection-based attacks.
