Reading Time: 3 minutes Overview A pointer is a general programming concept for a variable that contains an address in memory. In Rust, we have smart pointers in addition to normal pointers. Smart pointers are data structures that not only act as a pointer but also have additional metadata and capabilities. Box pointers are one of the smart pointers in Rust. Box Pointers Boxes allow you to store data on the heap Continue Reading
Reading Time: 4 minutes For any Data Scientist, its very normal to deal with data sets having missing terms and still be able to manage and create a good predictive model out of it. Here we will discuss some techniques to handle missing data in a given data set. Missing Value occur when no data is stored for a variable or feature. It could be represented as “?”, “NA”, Continue Reading
Reading Time: 5 minutes In this series of WebAssembly, I tell you about wasm and some useful CLI to have fun with wasm. WebAssembly is an open standard that defines a portable binary code format for executable programs, and a corresponding textual representation for interactions between such programs and their hosts. More than 20 companies reportedly use WebAssembly in their tech stacks, including Backend, Foretag, and Cubbit. C++, C, Rust, Blazor, and Yew Framework are some of the popular tools that can Continue Reading
Reading Time: 2 minutes In this blog, we will see how to read the Avro files using Flink. Before reading the files, let’s get an overview of Flink. There are two types of processing – batch and real-time. Batch Processing: Processing based on the data collected over time. Real-time Processing: Processing based on immediate data for an instant result. Real-time processing is in demand and Apache Flink is the Continue Reading
