    pubsub.slavino.sk / infoworldcom · Yesterday - 11:00 edit

Python developers cite simplicity and ease of use as principal reasons for using the language, but they still want capabilities such as static typing and performance improvements, based on survey results released this week.

Python’s simple syntax, syntactic sugar, and ease of learning were the most-favored features, capturing 37% of respondents, who were asked which three features they liked the most. Developers were polled in October 2020 as part of the annual Python Developers Survey . Being a high-level language with code that is easy to write and easy to read came second, with 30% of respondents citing these as their favorite three features.

    How to handle component interaction in React

    pubsub.slavino.sk / infoworldcom · Yesterday - 11:00 edit

Every React app is composed of interacting components. How these components communicate is an essential aspect of the UI architecture. As applications grow larger and more complex, component interaction becomes even more important.

React provides several methods for handling this need, each with its appropriate use cases. Let’s begin with the simplest approach, parent-to-child interaction.

Parent-to-child with props

The simplest form of communication between components is via properties — usually called props . Props are the parameters passed into child components by parents, similar to arguments to a function.

    Is geofencing a protective bubble or a heap of trouble?

    pubsub.slavino.sk / infoworldcom · Yesterday - 11:00 edit

Even if it were to end today, the COVID-19 crisis will leave an indelible imprint on the infrastructure of our lives. In addition to the painted lines, warning signs, and other low-tech indicators that attempt to keep people safely separated, we’re seeing greater interest in technological solutions to enforce quarantines of infected individuals and keep the coronavirus from spreading in crowds.

Geofencing for quarantine management

Although much attention has gone to contact tracing as a tool for tracking the virus’s spread, geofencing is a potentially more useful tool for enforcing these curve-flattening practices at the larger societal level, in every home, office, or other facility.

    TypeScript 4.2 tunes tuple types

    pubsub.slavino.sk / infoworldcom · 2 days ago - 20:18 edit

Microsoft has published the production release of TypeScript 4.2, an update to the popular open source language that adds types to JavaScript. Arrived February 23, TypeScript 4.2 features enhancements pertaining to tuple types and type aliases.

TypeScript 4.2 expands the ways rest elements in tuple types can be used. Previously, TypeScript only permitted rest elements in the last position of a tuple type. Now, rest elements can occur almost anywhere within a tuple, with a few restrictions. A rest element cannot be followed by another optional element or rest element, and only one rest element is permitted per tuple.

    Review: AWS AI and Machine Learning stacks up

    pubsub.slavino.sk / infoworldcom · 2 days ago - 11:00 edit

Amazon Web Services claims to have the broadest and most complete set of machine learning capabilities. I honestly don’t know how the company can claim those superlatives with a straight face: Yes, the AWS machine learning offerings are broad and fairly complete and rather impressive, but so are those of Google Cloud and Microsoft Azure .

Amazon SageMaker Clarify is the new add-on to the Amazon SageMaker machine learning ecosystem for Responsible AI. SageMaker Clarify integrates with SageMaker at three points: in the new Data Wrangler to detect data biases at import time, such as imbalanced classes in the training set, in the Experiments tab of SageMaker Studio to detect biases in the model after training and to explain the importance of features, and in the SageMaker Model Monitor, to detect bias shifts in a deployed model over time.
