Often people use Hadoop and other so-called Big Data™ tools for real-world processing and analysis jobs that can be done faster with simpler tools and different techniques.
Logistic regression is a simple classification method which is widely used in the field of machine learning. Today we’re going to talk about how to train our own logistic regression model in Python to build a a binary classifier. We’ll use NumPy for matrix operations, SciPy for cost minimization, Matplotlib for data visualization and no machine learning tools or libraries whatsoever.
The interface between frontend and API has become a common point of friction, challenge, and complexity. In an ideal world, backend and frontend would evolve together in harmony, with close communication, and the data served up by the backend would match exactly what the front-end needs.
The Web Authentication API gives Web applications user-agent-mediated access to authenticators – which are often hardware tokens accessed over USB/BLE/NFC or modules built directly into the platform – for the purposes of generating and challenging application-scoped (eTLD+k) public-key credentials.
‘Very few companies are going to be 100 percent compliant on May 25th’
Working with the latest and greatest is always exciting. As developers, we tend to download new software and SDKs in order to try it and, in some cases, benefit from early fixes or early access to new features. However, as developers, we're not restricted to our machines. Eventually, the code is pushed into source control and from there the CI/CD pipeline takes care of the deployment to the appropriate environment(s).
In this post we will learn about a great library called Polly. With this library we can define policies (you can see where the name came from) on how to deal with failed network requests. This library provides you with easy to use code that let’s you retry, fallback or define other methods to deal with a network request that doesn’t behave as it should.
In case you’re not familiar, GraphQL is a language-independent specification for client-server communication. It lets you model the resources and processes provided by a server as a domain-specific language (DSL). Clients can use it to send scripts written in your DSL to the server to process and respond to as a batch.
