An Open Source Portal for EducatorsThere are hundreds of open source projects ranging from simple email software to publicly dedicated WWW servers and full operating systems. This article describes an online platform for educators with free open source educational systems including wikis, blogs, bulletin boards, Content/Course Management Systems, and MOOs, all open systems which are easily installed and managed. By setting up a content-based server, educators can save and archive their files online easily, and integrate their online resources without needing web design skill. With full control of these different educational tools, educators can form a collaborative learning community based on their teaching goals. Thus teachers and students can build an online community as partners. They can learn from and with others, share and try out web learning tools, distribute leadership and inspiration, and support and interact with others from all over the world.
Although you might not know much about modern engines, would you buy a car with the hood welded shut? Yet most computer users rely on software whose code is not accessible to them. Meanwhile, there are hundreds of open source projects ranging from simple email software to WWW servers (e.g., Apache) and full operating systems (Linux) already available.
There are many good reasons to use open source systems:
1. Free: no payment, no advertisements
2. Full control: You can edit the settings and options according to your needs
3. Customization and Extensibility: If you know its computer language, you can edit the code to fit your own use
4. Friendly online support group

The camera integration kit consists of a baseboard and a plug-in board, containing a VS6×24 device in a socket package. Figure 1 shows the base board with the socket plug-in attached. Software is provided which allows easy demonstration of the available features. An external interface allows access to the camera data and control signals, allowing the user to pass video data directly to their application. The user will be able to control the camera through the USB 2.0 interface, or through their own application.
Initially, the camera must be set up using the USB 2.0 interface, after which the camera can be used in conjunction with both the USB 2.0 interface and the user’s application, or with the user’s application as a stand alone module. Figure 1. IMG-x24-E01 image

An apt analogy is a judge or jury that must take time to weigh evidence for alternative interpretations and/or possible ramifications before settling on a verdict. Here we evaluate progress in understanding how this process is implemented in the brain. Our scope is somewhat narrow: We consider primarily studies that relate behavior on simple sensory-motor tasks to activity measured in the brain because of the ability to precisely control sensory input, quantify motor output, and target relevant brain regions for measurement and analysis. Nevertheless, our intent is broad: We hope to identify principles that seem likely to contribute to the kinds of flexible and nuanced decisions that are a hallmark of higher cognition. SDT: signal detection theory SA: sequential analysis
The organization of this review is as follows. We first describe the computational elements that comprise the decision process. We then briefly review signal detection theory (SDT) and sequential analysis (SA), two related branches of statistical decision theory that represent formal, mathematical prescriptions for how to form a decision using these computational elements. We then dissect several experimental results in the context of this theoretical framework to identify neural substrates of decision making. We conclude with a discussion of the strengths and limitations of this approach for inferring principles of higher brain function.
Elements of a Decision
The decisions required for many sensory-motor tasks can be thought of as a form of statistical inference (Kersten et al. 2004,Generation Web 2.0Web 2.0 is the name for the latest internet technologies that enable users from around the world to connect online and share their knowledge and expertise. These technologies include blogs, wikis, social networking sites (MySpace, Bebo, Facebook), and community tagging tools (such as del.icio.us and Digg).
In online communities the norms around who has control, privacy and openness have shifted. Danah Boyd, a researcher with the University of Southern California, says that ‘New social technologies have altered the underlying architecture of social interaction and information distribution. They (young people) are embracing this change, albeit often with the clumsy candour of an elephant in a china shop. Meanwhile, most adults are panicking.’
These technologies, along with devices such as digital cameras, allow young people to be producers and consumers of content and services. Most will now have heard of YouTube and Flickr, sites that allow users to share, comment on and rate videos and photos. This is the era of the read/write web where anyone can publish and rules about what is acceptable/unacceptable are being re-written.

Mashups take ‘live’ data and represent it in many forms; for example, you may have seen community generated recommended restaurants on Google Earth. myfuture will soon offer users Google maps of where courses are offered and the nearest train station to the providers’ location.
Finally, technologies such as RSS (Really Simple Syndication) allow you to filter the increasingly complex information-rich worldRICOH Printing Systems DDP Server User's GuideThe DDP Server is essentially controlled from the network. Nonetheless, two control lights are provided on an operator panel at the front. They are useful to control the basic operation of the DDP Server. The operator panel also contains the standby button for switching the DDP Server on or off. For saving energy while the DDP Server is not used, DDP Server provides an additional power switch at the rear.
Furthermore, a small button is provided at the rear for special functions. This is only needed for setup and maintenance purposes.
The elements on the front side have the following functions:
• Standby button: This button allows you to power on or shut down the DDP Server.
To power on or shut down the DDP Server, press this button shortly. A regular shut down includes closing the job and queue database. When the DDP Server is running, you may force power down by holding the standby button for more than 4 seconds. However, you should force power-down only if the DDP Server does not react otherwise, as in this way the database is not closed and loss of the stored data may result. For the same reason, do not switch off the DDP Server by means of the power switch at the rear before performing a regular shutdown using the standby button.
• READY control light (green) with the following meanings:
Constant – DDP Server is idle
Blinking – DDP Server is busy
• ERROR control light (yellow) with the following meanings:
Constant – data transfer to printer
The followingFeed Injection in Web 2.0One new feature of "Web 2.0", the movement to build a more responsive Web, is the utilization of XML content feeds which use the RSS and Atom standards. These feeds allow both users and Web sites to obtain content headlines and body text without needing to visit the site in question, basically providing users with a summary of that sites content. Unfortunately, many of the applications that receive this data do not consider the security implications of using content from third parties and unknowingly make themselves and their attached systems susceptible to various forms of attack.
This white paper discusses various forms of attacks based on Web feeds that follow the RSS, Atom and XML standards. This paper does not extensively cover each XML element and its usage within Web-based feeds, nor does it address other vulnerability scenarios such as buffer overflows and other XML- specific risks. The goal of this paper is to outline the risks of lesser-known threats which are currently emerging on the Web utilizing Cross-Site Scripting
Web Feeds as Attack Vectors
Browsers, local readers, Web sites and online portals such as Bloglines all subscribe to feeds. These applications automatically fetch new content at intervals defined either on the receiving client or by the feed itself. Once a user is subscribed, they are alerted to new entries where they can read the story title and usually a brief description of the story body. The RSS Specification states that story bodies (the tag) allow HTML entities in order to allowMercedes-Benz ML 320 SE 420 SEL 500 SEL Operator’s ManualThe more cautiously you treat your vehicle during the break-in period, the more satisfied you will be with its performance later on. Therefore, drive your vehicle during the first 1500 km (1000 miles) at moderate vehicle and engine-speeds. During this period, avoid heavy loads (full throttle driving) and high RPM (no more than 2/3 of maximum permissible speed in each gear as indicated on the speedometer). Avoid accelerating by kickdown. It is not recommended to brake the vehicle by manually shifting to a lower gear. We recommend to select positions “3? or “2?only at moderate speeds (for hill driving). After 1000 miles (1500 km) speeds may be gradually increased to the permissible maximum Maintenance We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz dealer, in accordance with the Maintenance Booklet.
Failure to have the vehicle maintained in accordance with the Maintenance Booklet may result in vehicle damage not covered by the Mercedes-Benz Limited Warranty. Radio Transmitters Warning! Never operate radio transmitters equipped with a built-in or attached antenna (i.e. without the telephone connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunction of the vehicle’s electronic system, possibly resulting in an accident and personal injury. Radio transmitters, such as a portable telephone or a citicens band unit should only be used inside the passenger compartment, if they are connected to a Mercedes-Benz approved antenna that is installed on the outside of the vehicle.

Some system administrators even run software to detect portscanners and denial?of?service attempts. However, many system administrators still overlook security problems in CGI scripts and web applications.
As demonstrated by recent security alerts, improperly written CGI scripts and web applications can let crackers read system files, obtain passwords, crash the server or worse. A system may be firewalled and hardened against remote logins, FTP access and denial of service attacks, yet have many well?known holes in the server's web applications and CGI scripts.
Trapping 404 errors:
One method we have used to detect CGI script abuse is to redirect all "404 Not Found" responses from the web server to a script that examines the request for suspicious activity. Both Apache and iPlanet / Netscape web servers allow customized error messages. Either custom HTML files can be output or scripts can be executed in response to any of the standard HTTP request errors. Since a properly secured web server will not contain any of the well?known CGI vulnerabilities, any attempt by an outside to look for them results in a 404 Not Found response.
Apache comes with an example script "phf_abuse_log.cgi" you can use to log attempt to access phf. This concept can be expanded to look for any suspicious URL request (such any request containing "/etc/passwd" on a unix server) each time a 404 error is raised in the CGI?BIN directory. Instead of simply writing the activity to
