SQLrand: Preventing SQL Injection AttacksWe present a practical protection mechanism against SQL injection attacks. Such attacks target databases that are accessible through a web front-end, and take advantage of flaws in the input validation logic of Web components such as CGI scripts. We apply the concept of instruction-set randomization to SQL, creating instances of the language that are unpredictable to the attacker. Queries injected by the attacker will be caught and terminated by the database parser. We show how to use this technique with the MySQL database using an intermediary proxy that translates the random SQL to its standard language. Our mechanism imposes negligible performance overhead to query processing and can be easily retrofitted to existing systems.
The intuition behind such attacks is that pre-defined logical expressions within a pre-defined query can be altered simply by injecting operations that always result in true or false statements. This injection typically occurs through a web form and associated CGI script that does not perform appropriate input validation. These types of injections are not limited strictly to character fields. Similar alterations to the “where” and “having” SQL clauses have been exposed, when the application does not restrict numeric data for numeric fields.
Standard SQL error messages returned by a database can also assist the attacker. In situations where the attacker has no knowledge of the underlying SQL query or the contributing tables, forcing an exception may reveal more details about the table or its field names and types. This technique has been shown to be quite effective in practice.
OneMac OS - Make A Bootable MAC CD using Toast GuideThis information was compiled from the Roxio Toast web site, other Mac users, and my own experience. This information is not copyrighted (especially since I have borowed logos and trademarked names) so feel free to share it. Version 1.2 January 30, 2002 I was very frustrated! After creating six “coasters”, I thought there was no way to burn a bootable Mac CD using Toast. I followed their directions, the help I found on the Toast web site was unclear, and I downloaded someone else s instructions and just couldn’t do it.
While I’m not a computer expert, I have used Mac’s since (this dates me) 1985 and can probably do better troubleshooting and mechanical work than the geek that charges $75 an hour. So I poked around, put together the pieces of the puzzle and burned a bootable Mac OS CD. While I was doing that, I wrote this to help anyone else who was as frustrated as I was. Yes, it’s lengthy and detailed but if you follow step-by-step you won’t have any “coasters”. If you find any errors or omissions feel free to email me at thofts@mac.com. Thanks! - - Tom PS - Please keep the “stuffed” copy of this in your SHARED FOLDER so others on the network can get to it when I’m offline. –Thanks!

Its resources include semantically tagged Web sites, wikis, and blogs, as well as social networks, vertical search engines and a vast array of Web services from business processes to AI planners and domain models. Research prototypes of decentralized knowledge systems have been demonstrated for years, but now, thanks to the Web and Moore's Law, they appear ready for prime time. Architectural concepts for incrementally growing an Internet-scale knowledge system are introduced, with descriptions of early commercial deployments in manufacturing and healthcare.
I want to share a vision of how to build, or more precisely, grow Internet-scale knowledge systems. Such systems enable large numbers of human and computer agents to collaborate on solving complex problems in engineering, science, and business, or simply managing the complexities of life (say planning a trip or an event). It’s a vision that’s been evolving over 20 years since my days as an AI researcher, and more recently as an Internet entrepreneur. Thanks to the explosive growth of the Web, it’s a vision whose time has come. I also have a larger goal: to bridge the AI and Web communities, which have so much to give to and learn from each other.
25 years ago, at the birth of AAAI, Allan Newell articulated a set of criteria that a system had to exhibit to be considered intelligent (See Table 1). Newell was veryKeyimage Ontologization & Folksonomy in Web 2.0 Social SpaceThe Age of Image predates and is currently contemporaneous with the Information Age. In our times the explosive expansion of Web 2.0 Social Space, typified by the phenomena of De.licio.us, Flickr, MySpace, YouTube…, and the concomitant emergence of folksonomy, present interesting challenges in the management of this information. One key process by which to accomplish this in Social Space, is the wedding of folksonomy (of the people) with ontology (of the machine). Such a wedding must necessarily be conducted in the shared physicality of the word, of language. In this respect, WordNet together with OWL, play the role of matchmaker. But the same Social Space also provides an opportunity for natural folksonomical tagging by digiFoto (key)image.
The research harness for experimental keyimage tagging consists of Flickr as the main (digiFoto image) Social Space testbed and De.licio.us as the auxillary outreach secondary Social Space. Protégé Editor with OWL-DL provides the support for the bridge from keyimage to the formal ontology. The primary end user application domain is the keyimage tagging of paintings in an online art gallery.
BackStory
The research work reported on here is firmly situated within the emerging field of the Digital re-Discovery of Culture (DrDC) (Sotirova, 2005). Taking image (painting, photograph, publicity image (Berger, 1972, p. 129), television, film…) as typical focal point for (post)modern culture, we explore to what extent one can be lead to an experience of personal «physicality of soul» (FoS) in a playful way, an entertaining way, perhaps through a purposeful designed game (DrDCg) on theDI-704UP Ethernet Broadband Router and USB Print ServerConnecting The DI-704UP Broadband Router To Your Network

These systems suffer from several drawbacks: they each have a different way of providing access control which cannot be used with other systems; moving to a new system is a lengthy process and requires registration and invitation of all one’s friends to the new system; and the rules for access control are complicated and become more so as our networks of online friends grow.
In this paper, we present Lockr–an access control scheme based on social relationships that makes sharing personal content easy. Lockr separates social networking information from the content sharing mechanisms, thereby eliminating the need for users to maintain many site-specific copies of their social networks. We describe Lockr’s design, security properties, and limitations. We also present how we integrated Lockr with two popular systems for sharing content online – BitTorrent and Flickr.
Today, sharing personal content is surprisingly difficult. Current systems suffer from a number of drawbacks. They are cumbersome to use, they impose artificial limits on the size of shared content (e.g., pictures and video), and they make it difficult to restrict content only to a specific set of users. For those Web sites that do provide access control, they typically require all the participants to be registered with the site in question. This imposes the burden that users must register with many sites, and maintain separate and potentially inconsistent copies of their social networks for eachEclipse CDT TutorialEclipse is a framework for IDEs. It provides the infrastructure for the IDE, and then the IDE is completed by using a plug-in for a particular programming language. Plug-ins exist for Java (which was its first application), C/C++, Python, Perl and many others. Eclipse is multi-platform, runnable on Linux, Windows , etc. Eclipse came out of the Websphere project at IBM. Though the Eclipse project is now fully open-source, it is still strongly supported by IBM. In this tutorial, we will describe in step by step how to edit, compile and execute a C project using Eclipse in your EPS 254 lab computer.
Step 1: Staring Eclipse Log in to the Linux side of your machine. Start up Eclipse by typing eclipse in a command window. A Workspace Launcher window will appear as shown in Fig.1 which will ask you to specify a directory to use. Choose your working directory and select OK.
