Social media accounts are valuable for hackers for spreading phishing links, malware and spam. Furthermore, some people deliberately hack an acquaintance to damage his or her image. This paper describes a classification for detecting hacked Twitter accounts. The model is mainly based on features associated with behavioural change such as changes in language, source, URLs, retweets, frequency an...

Male putty-nosed monkeys have two main alarm calls, pyows and hacks. While pyows have a broad distribution suggestive of a general call, hacks are often indicative of eagles. In a series of articles, Arnold and Zuberbühler showed that putty-nosed monkeys sometimes produce distinct pyow-hack sequences made of a small number of pyows followed by a small number of hacks; and that these are predict...

In recent years, wireless networks have become increasingly common and an increasing number of devices are communicating with each other over lossy links. Unfortunately, TCP performs poorly over lossy links as it is unable to differentiate the loss due to packet corruption from that due to congestion. In this paper, we present an extension to TCP which enables TCP to distinguish packet corrupti...

Weblint is a utility for checking the syntax and style of HTML pages. It was inspired by lint [15], which performs a similar function for C and C++ programmers. Weblint does not aspire to be a strict SGML validator, but to provide helpful comments for humans. The importance of quality assurance for web sites is introduced, and one particular area, validation of HTML, is described in more detail...

This paper reports the study on the performance enhancements of two extensions to the standard TCP implementation Selective Acknowledgement (SACK) and Header Checksum (HACK) over satellite links that are characterized by high latency and high bit error rate. We also examine the effectiveness of TCP Trunk, an edge-to-edge aggregation and congestion control mechanism, over the satellite link. Our...
