This builds on the previous post on recursive square matrix multiplication. The steps of the Strassen’s method from Introduction to Algorithms, Third edition is as follows: Divide the input matrices A and B and output matrix C into n/2 x n/2 submatrices, as in equation (4.9). Create 10 matrices S1, S2,…, S10 , each of […]

The following algorithm for square matrix multiplication is from the Introduction to Algorithms, Third edition: The divide-and-conquer algorithm to compute the matrix product C = A . B, with the assumption that n is an exact power of 2 in each of the n x n matrices. The equation 4.9 mentioned in the algorithm is […]

Although this is demonstrated in an ubuntu environment you can use this tutorial to install java in any linux machine where curl, zip and unzip commands are installed. You can install java 6, java 7, java 8 , java 9 , java 10, java 11 , java 12 and java 13 using this method easily […]

These are the two documentations on the Core API in the ActiveMQ Artemis site: https://activemq.apache.org/components/artemis/documentation/latest/address-model.html https://activemq.apache.org/components/artemis/documentation/latest/core.html I read and reread through these articles and couldn’t figure out what Routing Type means with regard to Messages, Queues and Addresses in ActiveMQ Artemis. So here is a mail I sent them to get clarifications on the topic: […]

In Ballerina WebSocket is recognized as an upgrade from HTTP. Hence path parameter and query parameter supports are provided in WebSocket during this upgrade. We noted about the HTTP to WebSocket upgrade resource in a previous tutorial. This resource is basically a HTTP resource in an HTTP service with different annotations to differentiate it from […]

This tutorial demonstrates the creation of a WebSocket multiplayer game server using Ballerina. It uses a javascript WebSocket client. Some points of clarification: The ^”left” used in the code is because left and right are keywords in Ballerina and ^ is used to escape it. Also main point to note would be the data binding […]

Some points of clarification: The ^”type” used in the code is because type is a keyword in Ballerina and ^ is used to escape it. Watch in full HD for better clarity. Find the code used in […]

The transport of Ballerina has been implemented using netty. We ran the autobahn test suite against an implementation of WebSocket server and client to identify the spec compliancy of our implementation. There were several unaddressed issues identified during this process and we made several fixes to get this to be spec compliant. You can view […]
