An introduction to audio processing and machine learning using Python

12 hours 50 min ago

Features, defined as "individual measurable propert[ies] or characteristic[s] of a phenomenon being observed," are very useful because they help a machine understand the data and classify it into categories or predict a value.

How Ansible brought peace to my home

Tuesday 17th of September 2019 07:03:00 AM

A few months ago, I read Marco Bravo's article How to use Ansible to document procedures on Opensource.com. I will admit, I didn't quite get it at the time.

How to start developing with .NET

Monday 16th of September 2019 07:02:00 AM

The .NET framework was released in 2000 by Microsoft. An open source implementation of the platform, Mono, was the center of controversy in the early 2000s because Microsoft held several patents for .NET technology and could have used those patents to end Mono implementations. Fortunately, in 2014, Microsoft declared that the .NET development platform would be open source under the MIT license from then on, and in 2016, Microsoft purchased Xamarin, the company that produces Mono.

Monday 16th of September 2019 07:00:00 AM

There are many different ways to solve problems in computing. You might "brute force" your way to a solution by calculating as many possibilities as you can, or you might take a procedural approach and carefully establish the known factors that influence the correct answer. In constraint programming, a problem is viewed as a series of limitations on what could possibly be a valid solution.

What politics can teach us about open source

Friday 13th of September 2019 07:00:00 AM

Many sobering lessons from history emphasize democracy is not a finished product. The Roman Empire ended in a dictatorship, while the feudal Middle Ages delivered the Magna Carta and the Renaissance; despite the American Revolution, slavery continued for many years, while the French Revolution resulted in the restoration of the monarchy. That said, more people are living in democracies around the world today than at any time before, and living standards in democracies continue to improve.

How to fix common pitfalls with the Python ORM tool SQLAlchemy

Thursday 12th of September 2019 07:02:00 AM

Object-relational mapping (ORM) makes life easier for application developers, in no small part because it lets you interact with a database in a language you may know (such as Python) instead of raw SQL queries. SQLAlchemy is a Python ORM toolkit that provides access to SQL databases using Python. It is a mature ORM tool that adds the benefit of model relationships, a powerful query construction paradigm, easy serialization, and much more.
