SSH (Secure SHell) is a network protocol which provides a replacement for insecure remote login and command execution facilities, such as telnet, rlogin and rsh. SSH encrypts traffic in both directions, preventing traffic sniffing and password theft. SSH also offers several additional useful features:
• Compression: traffic may be optionally compressed at the stream level.
• Public key authentication: optionally replacing password authentication.
• Authentication of the server: making ”man-in-the-middle” attack more difficult
• Port forwarding: arbitrary TCP sessions can be forwarded over an SSH connection.
• X11 forwarding: SSH can forward your X11 sessions too.
• File transfer: the SSH protocol family includes two file transfer protocols.

Create JSF-like components, using JSP tag files
Learn how to use deferred values and deferred methods in custom JSP tag
JavaServer Pages (JSP) and JavaServer Faces (JSF) used to have different variants of the Expression Language (EL). Their unification in JSP 2.1 opened new possibilities, allowing you to use deferred values and deferred method attributes in your custom JSP tags. This article shows how to develop Java™ Web components based on JSP tag files, which are much simpler and easier to build than the JSF components.

To remain relevant in the Web 2.0 era it is important for an operator to first identify the unique network assets they have and then design an architecture that will maximize their usage, while at the same time protect them. Mobile operators are currently at risk of becoming bit-pipes as a result of the latest web technologies and properties. Competition is becoming very intense and operator revenues are likely to substantially decrease as a result. And by the time a mobile industry standards committee has the chance to meet, analyze and agree on a situation or latest protocol to create and deliver a new service, numerous Web 2.0 sites will have already come and gone.

Modern Geographical Information Systems (GIS) [1] provide a service-oriented architecture for interacting with geographical data sets and related maps. Web-based GIS systems are architected around the same principles as more general Web service systems based on SOAP [2], WSDL [3], and REST. Mirroring the World Wide Web Consortium and OASIS Web service standards-making bodies, the Open Geospatial Consortium [5] defines open standards for messages, XML data formats, and access protocols that are specific to the GIS community. In addition to OGC-based services, there are many companies (such as ESRI and AutoDesk) that provide proprietary, commercial solutions. Services from these various providers are not normally interoperable.

Web 2.0 – user-generated content, rich user interfaces and co-operative, dynamic services – has also brought with it a new and extremely virulent breed of ‘Malware 2.0’. A key motivation for this study is the link between Web 2.0 and the increase in ‘drive-by’ malware infections requiring no intervention or awareness on the part of the user. To give some idea of the threat posed, a Scansafe report analysing malware trends reports that risks from compromised websites increased 407% in the year to May 2008.

Participation
Every aspect of Web 2.0 is driven by participation. The transition to Web 2.0 was enabled by the emergence of platforms such as blogging, social networks, and free image and video uploading, that collectively allowed extremely easy content creation and sharing by anyone.

The TL-WA501G 54Mbps Wireless Access Point is the basic building block of a wireless LAN infrastructure. It provides connectivity between Ethernet wired networks and radio-equipped wireless notebook systems, desktop systems, print servers, and other devices.
The TL-WA501G 54Mbps Wireless Access Point acts as a bridge between the wired LAN and wireless clients. Connecting multiple TL-WA501G Access Points via a wired Ethernet backbone can further lengthen the wireless network coverage. As a mobile computing device moves out of the range of one access point, it moves into the range of another. As a result, wireless clients can freely roam from one Access Point to another and still maintain seamless connection to the network.

Extensible Markup Language (‘XML’) is a standard for describing content data in a manner that facilitates the sharing of such content across different systems and applications. Over the last 10 years, the XML standard has been adopted across a wide range of environments in the IT industry. Microsoft is one of many companies that is re-aligning its existing product range to take advantage of the flexibility of XML. One of its current initiatives is the standardization of the Office Open XML File Formats (‘File Formats’).This paper reviews the standardisation process that Microsoft has embarked upon and examines Microsoft’s legal arrangements related to intellectual property associated with the File Formats and the manner in which that legal treatment interacts with other products currently on the market.
