Consuming RESTful services in PHP
Here are the key steps to load data from a RESTful service using AJAX and jQuery:
1. Make an AJAX GET request to the REST API endpoint using jQuery.ajax() or jQuery.getJSON().
2. Specify the URL, set the data type to "json", and provide a success callback.
3. On success, the JSON response will be passed to the callback function where it can be used to update the UI.
4. Parse the JSON response into a JavaScript object for easy access to the data.
5. Update the HTML using the jQuery DOM manipulation methods like html(), text(), etc.
So in summary - make an AJAX GET, parse the JSON response,
CGI Presentation
The document provides an overview of CGI (Common Gateway Interface) and how it enables dynamic web content. It discusses how CGI works, alternatives like PHP and Java servlets, configuring Apache web server for CGI, programming CGI applications using Perl and the CGI.pm module, handling input/output and errors. It also includes an example CGI application in Perl for counting button clicks using sessions and cookies to manage state.
Java servlets and CGI

Less Is More: Utilizing Ballerina to Architect a Cloud Data Platform
At its core, the challenge of managing Human Resources data is an integration challenge: estimates range from 2-3 HR systems in use at a typical SMB, up to a few dozen systems implemented amongst enterprise HR departments, and these systems seldom integrate seamlessly between themselves. Providing a multi-tenant, cloud-native solution to integrate these hundreds of HR-related systems, normalize their disparate data models and then render that consolidated information for stakeholder decision making has been a substantial undertaking, but one significantly eased by leveraging Ballerina. In this session, we’ll cover:
The overall software architecture for VHR’s Cloud Data Platform
Critical decision points leading to adoption of Ballerina for the CDP
Ballerina’s role in multiple evolutionary steps to the current architecture
Roadmap for the CDP architecture and plans for Ballerina
WSO2’s partnership in bringing continual success for the CD
Modernizing Legacy Systems Using Ballerina
The integration landscape is changing rapidly with the introduction of technologies like GraphQL, gRPC, stream processing, iPaaS, and platformless. However, not all existing applications and industries can keep up with these new technologies. Certain industries, like manufacturing, logistics, and finance, still rely on well-established EDI-based message formats. Some applications use XML or CSV with file-based communications, while others have strict on premises deployment requirements. This talk focuses on how Ballerina's built-in integration capabilities can bridge the gap between "old" and "new" technologies, modernizing enterprise applications without disrupting business operations.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
