周佛海人生三步曲蜕变研究

周佛海曾是出席中国共产党"一大"的十三个代表之一,后来却投靠了国民党右派,再后来卖身给日本侵略者,堕落为臭名昭著的汉奸卖国贼。周佛海人生三步曲的蜕变是由于其个人野心不断恶性膨胀以及对共产主义丧失信念的结果。我们今天从反面总结他一生的教训,对于我们树立正确的人生观很有意义。     

African nations as proxies in covert cyber operations

The growth of the African Internet, and services related to the Internet, has been rapid over the last decade. Following this market expansion, a variety of service providers have started to provide access. A fast-growing market puts pressure on the providers to deliver services first and only then seek to secure the networks. Over time, industrialised nations have become more able to detect and trace cyber attacks against their networks. These tracking features are constantly developing and the precision in determining the origin of an attack is increasing. A state-sponsored cyber attacker, such as intelligence agencies and electronic warfare units, will seek to avoid detection, especially when the attacks are politically sensitive intelligence-gathering and intrusion forays into foreign states' networks. One way for the attacker to create a path that links the attacks and the originating country is by actions through a proxy. The less technologically mature developing nations offer an opportunity for cyber aggression due to their lower level of security under the quick expansion of the Internet-based market. Developing countries could be used as proxies, without their knowledge and consent, through the unauthorised usage of these countries' information systems in an attempt to attack a third country by a state-sponsored offensive cyber operation. If the purpose of the cyber attack is to destabilise a targeted society and the attack succeeds, the used proxies are likely to face consequences in their relations with foreign countries, even if the proxy was unaware of the covert activity.

一个基于面向对象模型的并行系统

为了开发分布式系统中的计算资源,我们设计了一个基于面向对象大粒度数据流模型的并行Ｃ＋＋系统ＯＯＣＰＣＳ．该系统的底层计算模型是面向对象范式和数据流模型的结合体。它将状态对象引入到数据流模型中,并且支持面向对象的特性。本文讨论了此模型在ＯＯＣＰＣＳ系统中的实现;并行化编译器;ＰＯＣ程序设计语言;面向对象网络文件Ｉ／Ｏ和虚拟ＯＯＬＧＤＦＭ机
