Mobile Agents: Are They a Good Idea?

by David Chess, Colin Harrison, Aaron Kershenbaum, T. J. Watson , 1995
"... Mobile agents are programs, typically written in a script language, which may be dispatched from a client computer and transported to a remote server computer for execution. Several authors have suggested that mobile agents offer an important new method of performing transactions and information ret ..."

Aglets: a good idea for Spidering?

Introduction Many individuals and businesses now rely on the Web for promulgating and finding information, and in particular, rely on centralised search databases. The extent to which these databases reflect the "contents" of the Web in an accurate and timely manner is now under considerable doubt, and in any event, it is apparent that the methods used by the search engines for finding new and modified Web documents are not scaling well. To ameliorate these problems, we have been exploring the use of a "data push" model for notifying Web changes, to replace the current "data pull" model, which uses aglets (aka servlets or peerlets) to distribute the indexing task. Aglets are objects with a thread of control, that can migrate autonomously between processors in a distributed environment. As currently proposed and implemented, aglets have very few of the properties of Persistence. But as they inhabit a similar conceptual space, their properties and applications pr

Is finding security holes a good idea

The underlying rationale for this activity is that it increases welfare by decreasing the number of vulnerabilities available for discovery and exploitation by bad guys, thus reducing the total cost of intrusions. ..."

Alarge amount of effort is expended every year on finding and patching security holes. The underlying rationale for this activity is that it increases welfare by decreasing the number of vulnerabilities available for discovery and exploitation by bad guys, thus reducing the total cost of intrusions. Given the amount of effort expended, we would expect to see noticeable results in terms of improved software quality. However, our investigation provides a mixed answer: the data does not allow us to exclude the possibility that the rate of vulnerability finding in any given piece of software is constant over long periods of time. Ifthere islittle or no quality improvement, then we have no reason to believe that that the disclosure of vulnerabilities reduces the overall cost of intrusions. 1

Why bad ideas are a good idea

RISK AND RESILIENCE: FROM GOOD IDEA TO GOOD PRACTICE

Resilience has gained significant prominence following the re-examination of the performance of the humanitarian and development aid systems in light of the two major food security crises in East and West Africa over the last two years, coupled with ongoing ‘post-2015 ’ negotiations on key global disaster risk reduction, climate change and development policy and resourcing. Resilience has largely been communicated by donor and other key actors as a political agenda, devoid of clear technical guidance as to its added value and how it changes programming on the ground. As a result, country staff are either cynical of its value, are confused as to what it means, or use it as another opportunity to attract funding or to justify their narrow institutional mandate. There are relatively few actors who engage with resilience armed with specific technical guidance informed by comprehensive risk and vulnerability analyses. The continued ‘improper ’ application of resilience reinforces some views that this is another ‘buzzword ’ or ‘fad’, devoid of real meaning for programming, and will mean that the approach will be eventually dropped from policy and programming when ‘the next big thing ’ comes along. This study argues that resilience has sufficient technical added-value (distinct from resilience as a political agenda) and outlines how it can be applied to programming, and, in response to challenges on the ground

When is a Communicative Agent a Good Idea?

by Patrick Doyle - In Workshop on “Communicative Agents: The Use of Natural Language in Embodied Systems”, Third International Conference on Autonomous Agents , 1999
"... Research suggests humans treat computers in social ways. We understandably have an interest in building interfaces that use embodiment and natural language to conform to these social roles. However, we must be careful how and when we embed these agents so they actually improve on existing interfaces ..."

Research suggests humans treat computers in social ways. We understandably have an interest in building interfaces that use embodiment and natural language to conform to these social roles. However, we must be careful how and when we embed these agents so they actually improve on existing interfaces, rather than simply making them more social.

What good are positive emotions

by Barbara L. Fredrickson - Review of General Psychology , 1998
"... This article opens by noting that positive emotions do not fit existing models of emotions. Consequently, a new model is advanced to describe the form and function of a subset of positive emotions, including joy, interest, contentment, and love. This new model posits that these positive emotions ser ..."

Operating Systems on SoCs: A good idea?

System on a chip (SoC) designs penetrate in an increasing rate the embedded systems market. This a#ects the consumer market as well as other areas, like automotive or aerospace. As the computational power of CPU cores on such SoC increases, the use of operating systems (OS) as basis for the application becomes more and more an issue. This paper investigates the specific requirements of SoCs and analyses to what degree microkernel based OSes have any advantage over standard embedded real-time operating systems. It concludes that temporal and functional verification of OSes are of fundamental importance and that so far no embedded OS fulfills these criteria. However, it seems microkernels seem to support this better that other embedded OSes.
