AJAX stands for Asynchronous JavaScript And XML. It allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes, without interfering with the display and behavior of the existing page. AJAX uses XMLHttpRequest object to request data from the server and JavaScript is used to display or use the data. The steps include creating an XMLHttpRequest object, making a request to the server using open() and send() methods, monitoring the response using onreadystatechange event handler, and updating the webpage with the response data.

Ajax stands for Asynchronous JavaScript and Xml. Ajax is not a single technology, but a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with JavaScript to dynamically display, and allow the user to interact with, the information presented. JavaScript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Ajax Technology
1. AJAX
AJAX stands for Asynchronous JavaScript And XML.
Any server side technology that supports JavaScript also
supports AJAX.
AJAX is a browser technology, and is therefore independent of
web server platforms.
AJAX is not a programming language, so you don’t have to
learn any new technology. AJAX can be implemented by using
existing standards (JavaScript and XML) in a different way.
AJAX uses HTTP requests for this. With AJAX, JavaScript
communicates directly with the server, through the JavaScript
XMLHttpRequest object (XML over HTTP)
2. AJAX to request a data from the server we need
• 1. Create an XMLHttpRequest object.
• 2. Then using this object, request data from the server.
• 3. JavaScript will then monitor for the changing of state of the
request.
• 4. If the response is successful, then the content from the
data store requested will be returned as response (response
can be in the form of a String or XML).
• 5. Use the response in your web page.
3. 1.Create an XMLHttpRequest object
• JavaScript has a built-in XMLHttpRequest object
• For Internet Explorer use the ActiveXObject
4. var req;
XMLHttpRequest for all browsers :
if(window.XMLHttpRequest)
{
//For Firefox, Safari, Opera
req = new XMLHttpRequest();
}
else if(window.ActiveXObject)
{
//For IE 5
req = new ActiveXObject(“Microsoft.XMLHTTP”);
}
else if(window.ActiveXObject)
{
//For IE 6+
req = new ActiveXObject(“Msxml2.XMLHTTP”);
}
Else
{
//Error for an old browser
alert(‘Your browser is not IE 5 or higher, or Firefox or Safari or Opera’);
}
5. 2. Request for a web page
• After creating the XMLHttpRequest we now need to send the web request
using the open method. We also need to specify the HttpRequest method,
GET or POST. Use the following code to send the request.
• Use the following code to send the request.
• req.open(“GET”,”somedata.php”);
• req.send(null);
• Here, req is the XMLHttpRequest object. It will request to the server for
somedata.php using GET method. The open function also has a third
parameter, an optional boolean parameter. You should set that to true :
• req.open(“GET”,”somedata.php”,true);
• req.send(null);
• Both of the above is correct.
6. 3. Monitor for the response of the request
• For doing this you can assign a function to
req.onreadystatechange (Here, req is the
XMLHttpRequest object), like below.
• req.onreadystatechange=function()
{
if(req.readyState==4 && req.status == 200)
{
var resp = req.responseText;
}
}
7. like this
• req.onreadystatechange = handleResponse;
• function handleResponse()
{
if(req.readyState == 4 && req.status == 200)
{
//returned text from the PHP script
var response = req.responseText;
}
}
8. • The readyState property holds the status of the server’s response.
Each time the readyState changes, the onreadystatechange
function will be executed. Here are the possible values for the
readyState property:
• State Description
• 0 The request is not initialized
• 1 The request has been set up
• 2 The request has been sent
• 3 The request is in process
• 4 The request is complete
• And status is the status of the HTTP Request, like 500 Internal
Server Error, 400 Bad Request, 401 Unauthorized, 403 Forbidden,
404 Not Found etc. 200 means no error.
9. 4. Get the response
• The response will be as string or as XML. The data sent back
from the server can be retrieved with the responseText
property as string. Use responseXML for getting the response
as XML.
10. 5. Use the response on your web page
• You can use the response you got from the XMLHttpRequest
in your web page/application. You can either set a value of a
text field or use the returned HTML from the web request as
innerHTML for a <div></div> tag or <span></span> tag (See
below for the implementation of this)
