This slide deck examines new product releases from credit card carriers in our Credit Card Monitor coverage group.
Inside, we provide a rundown of the new products introduced on the firm’s websites during the 2014 year, and highlight their key features.
TCP sockets allow for communication between applications over the internet. A server creates a ServerSocket to listen for incoming connections on a specific port. When a client connects, the server accepts the connection to get a Socket. Both client and server then obtain input and output streams from the Socket to send and receive data. The connection is closed once communication is complete. Multithreading allows servers to handle multiple clients concurrently by spawning a new thread for each connection.
Translation Technologies & Business in the FutureMultilizer
Niko Papula from Multilizer discusses how language technologies will impact business in the future. Machine translation is increasingly being used alongside human translation to improve efficiency. While still imperfect, machine translation volumes are enormous and provide value. Text analysis is key to understanding large amounts of data and identifying trends. Three global trends - unified communication, information access, and user experience - are driving huge demand for language technology solutions. While challenging the traditional translation industry, language technologies also provide opportunities for innovative companies. Finland risks falling behind globally if it does not actively develop and apply language technologies.

We are meeting at Erin United Church's Fellowship Room to send a message about climate change and faith. While governments have agreed to limit global warming to 2 degrees Celsius, current trajectories have us on a path to warm by 4 degrees. The meeting highlights solutions like using one hour of sunlight, which equals the Earth's annual energy needs, and biomimicry projects in Zimbabwe. The timing is good as important climate announcements were made just this week. The document encourages letting dreams be bigger than fears, actions louder than words, and faith stronger than feelings, noting that faith involves taking the first step even when the entire path isn't visible.
The document discusses domain name providers and top level domains. It provides tables comparing the pricing of various domain extensions like .com, .net, .org, .mx, etc. from different domain name registrars. It also defines the meaning and typical uses of some common top level domains such as .com, .net, .org, .info, .tv, and .name. Finally, it provides a brief description of what a web hosting service is and some of its key functions.

Strong waves erode and deposit material on shorelines over time, forming various landforms. These include sea cliffs created as wave-induced cracks in rock expand and break off pieces. Sea caves are also formed as weaker rocks are carved out by wave erosion. When erosion joins cracks close to each other, sea arches form. Further erosion can cause arch roofs to collapse, leaving behind stacks. Beaches are landforms created through the temporary deposition of sand and soil by wave action.

This document discusses innovative teaching methods in biology that incorporate local resources and hands-on learning. It provides examples of how various biological components like proteins, lipids, and minerals can be taught about and used to explain their importance in living organisms and the environment. Students are shown experimenting with different biological samples and learning about their structures and roles through discussion. The summary emphasizes hands-on, collaborative learning around real-world examples to help students make deeper connections between biology, their surroundings, and their culture.
The document discusses how to programmatically make URL requests in Java. It covers using the URL and URLConnection classes to (1) parse URLs, (2) retrieve URL contents by opening connections or streams, and (3) get header information. It also provides examples of how to fake GET and POST form submissions by encoding parameters and sending requests via URLConnection.
Servlets are Java programs that run on a web server and generate dynamic web page content. Servlets receive HTTP requests and return HTTP responses. They provide an interface between web clients and web servers. Key points:
- Servlets run on web servers like Tomcat and handle HTTP requests/responses dynamically.
- They extend the HttpServlet class and implement doGet() and/or doPost() methods to process requests.
- Servlets can access request parameters, headers, cookies and generate HTML responses by setting headers and writing to the response.
- Servlets are configured in the web server and mapped to URLs to handle requests for those URLs dynamically.
Cookies allow servers to store and retrieve information on the client side. Servers send cookies in HTTP responses and browsers send the cookie back with subsequent requests. There are two main methods for managing sessions between clients and servers - using session cookies or URL rewriting. With session cookies, the server embeds a session ID in a cookie it sends to the client, and the client sends the cookie back on future requests to identify the session. With URL rewriting, the server encodes the session ID directly into the URLs of links and redirects. The session data itself is stored server-side and associated with the client via the session ID.
The document discusses cryptography functions like secret key encryption, public key encryption, and message digests. It also discusses security services like privacy, authentication, and integrity. Cryptography algorithms are used to provide these security services. Secret key encryption uses a single key for encryption and decryption while public key encryption uses separate public and private keys. Message digests are used to verify integrity through cryptographic checksums.
Remote Method Invocation (RMI) allows programmers to execute remote functions and calls using the same semantics as local function calls. RMI uses stubs and skeletons, where the stub acts as a proxy for the remote object on the client side and the skeleton receives the calls on the server side. To use RMI, an interface must be defined and implemented on the server, stub and skeleton classes are generated, the remote object is registered with an RMI registry, and then clients can look up and invoke methods on the remote object.
The document discusses Java Database Connectivity (JDBC) and how it allows Java code to execute SQL statements inside relational databases. It covers the JDBC API and how it provides a standard interface to different databases. It also discusses the JDBC-ODBC bridge which allows Java code to access databases via ODBC. The document provides an example of JDBC code to connect to a database, execute a query, and access the result set. It discusses using connection pooling and JNDI lookups in J2EE applications to connect to databases.
The JavaMail API allows Java applications to send and receive email. It includes core classes like Session, Message, Transport, and Store. A Session represents a mail session with an email server. Messages can be composed and sent using Transport, and email can be retrieved from mailboxes using Store and Folder classes. The API supports authentication, sending attachments, and receiving notifications about mail events.
1. TCP provides connection-oriented and reliable byte-stream communication between applications over IP networks. It uses flow control and congestion control to ensure reliable data delivery.
2. A TCP connection is established through a 3-way handshake where the client and server exchange SYN and ACK packets to synchronize sequence numbers and establish the connection.
3. Data is transferred in segments containing sequence numbers. ACKs confirm received segments and allow out-of-order delivery. Buffers store unacknowledged data.
4. Connections close through an orderly shutdown with FIN packets from each end acknowledging the other's end of data, followed by a TIME_WAIT state to detect lost ACKs.
The document discusses Java UDP sockets and networking. It explains how to use the InetAddress class to represent IP addresses, and the DatagramSocket and DatagramPacket classes to send and receive UDP datagrams. It provides code examples for both client and server implementations of UDP networking in Java using these classes.
This document provides an overview of using the Java Secure Socket Extension (JSSE) to enable secure socket communication in Java applications. It discusses key topics like the Java Cryptography Architecture (JCA), public-key cryptography, certificates, and the SSL/TLS handshake protocol. The goal of the tutorial is to provide instructions for configuring and using JSSE to encrypt client-server applications.
Java Server Faces (JSF) is a Java web development framework that provides reusable UI components and a component-based MVC architecture. Key aspects of JSF include:
- Clean separation of behavior and presentation using a component-based MVC model.
- Standard UI components and events tied to server-side code.
- Typical JSF applications include JavaBeans for state/behavior, event-driven development, and JSP view pages that reference a component tree.
The example JSF calculator application demonstrates:
1) Configuring the Faces servlet and managed beans.
2) Developing a model class and controller to mediate between the view and model.
3) Creating
Beans are commonly used to represent HTML form data. A bean class defines properties that correspond to form fields and get/set methods to access these properties. When a form is submitted, a bean is instantiated and its properties are set from the form data using setProperty. The bean properties can then be accessed as needed, such as to perform calculations or display the data on a response page. This follows the MVC pattern with the bean representing the model, the JSP pages representing the view, and a controller handling form submission and forwarding requests.
The document provides an overview of the Java Persistence API (JPA). It describes JPA as an API for managing Plain Old Java Objects (POJOs) and mapping their state and relationships to a relational database. It discusses key JPA concepts like entities, the entity manager, queries, object-relational mapping, and common annotations.
This document provides examples and explanations of different types of Enterprise JavaBeans (EJBs), including stateless session beans, stateful session beans, entity beans, and container-managed persistence. It describes the home and remote interfaces, bean classes, required bean methods, and example client code for each EJB type. It also discusses entity bean mappings, characteristics, and how they represent persistent data stored in a database. Finally, it briefly outlines the multitiered J2EE application model and database connection pooling techniques.
CORBA allows for cross-platform communication between software components. It uses an Object Request Broker (ORB) to connect client objects to server objects across a network. Interfaces are defined using the Interface Definition Language (IDL) and compiled to generate stubs and skeletons in various programming languages. Clients locate objects by querying a naming service, then call methods on remote objects using the stubs.
This document provides an introduction to AJAX and guides the reader through four steps to make a basic AJAX request: 1) Create an XMLHttpRequest object to make HTTP requests, 2) Set up the request and handle the response, 3) Make a simple request to an HTML file and display the response, 4) Make a request to an XML file and parse the response using DOM methods.
Enterprise JavaBeans (EJBs) are reusable software components that can represent either data (entity beans) or business logic (session beans). EJBs provide benefits like transaction management, security, and the ability to be deployed on application servers. There are different types of session beans, including stateful and stateless, and entity beans can use either bean-managed or container-managed persistence to access a database. To use an EJB, a client first locates its home interface using JNDI and then calls methods on the home interface to access the bean.
