President - Association of Computer Engineering Students

I was selected to be the president of ACES, Association of Computer Engineering Students, the official student body of the Department of Computer Engineering Students. ACES Site :  aces.ce.pdn.ac.lk  It was a great opportunity to work with fellow undergraduates, lecturers, senior graduates, and industry. Until now We were able to organize few events in University of Peradeniya and Colombo. This event was organized by ACES Council, a group of 14 undergraduates. The events are, ACES Hackathon - This is an inner hackathon for undergraduates in the University of Peradeniya. ACES Hackathon, held annually for the last 5 years was held from the 29th of April to the 1st of May 2016 at the Faculty of Engineering, University of Peradeniya.

Idea details KIE Management Application (with REST api and UI) Status:  Final Summary of idea:  Build management extension and UI for KIE Server The project is about creating management extension to KIE Server (lightweight embeddable rule, process execution server) to manage it remotely. Typical management operations are: - manage containers (deploy/undeploy, upgrade etc) - view process instances and perform administration actions on them like cancelling, migrating etc - view tasks as admin - delegate, f...

An API receives requests and sends back responses through internet protocols such as HTTP, SMTP, and others.  Many popular websites provide public APIs for their users, for example, Google Maps has a  public REST API  that lets you customize Google Maps with your own content. There are also many APIs that have been created by companies for internal use. There are significant differences between SOAP and RESTful web services. The bullets below break down the features of each web service based on personal experience. REST RESTful web services are stateless. You can test this condition by restarting the server and checking if interactions survive. For most servers, RESTful web services provide a good caching infrastructure over an HTTP GET method. This can improve the performance...
