Integrating Pipenv and Azure Private Package Indexes

Pipenv is a popular tool for automatically creating and managing Python virtual environments and installing and managing pip packages.

For more information on pipenv, the problems it solves and its benefits checkout the first page of the pipenv docs: Pipenv: Python Dev Workflow for Humans.

Unfortunately, using Azure private package indexes present some technical challenges regarding authentication. Specifically, Azure uses a web based authentication workflow that needs some addition configuration to work with pipenv.

It is assumed that you have a python and pip installed and added to your shell’s path. It's generally recommended to pip install to the user site using --user; however, I found that these user directories are typically not added to the path.

Windows Terminal

Windows Terminal is a modern feature-rich open source terminal from Microsoft that runs many shells, including PowerShell. The easiest way to install it is from the Microsoft Store.

Go ahead and open Windows Terminal, which should default to PowerShell. Have a look around, it's already pretty awesome. There's support for multiple tabs, color schemes, custom fonts, custom shells, and more. We are going to customize it even further by setting up git support, customizing the prompt, installing custom fonts, setting the color scheme, and optionally adding a couple of extra tools.

posh-git and oh-my-posh

posh-git allows git information to be displayed within PowerShell and provides tab completion of git commands and branches.

oh-my-posh is a prompt theme engine for PowerShell.

Linq Any() performance compared to Count() > 0

I often see .Count() > 0 or .Count > 0 to check if there are any elements in some collection. Linq provides an Any() method to check if there are any elements. Any() sure reads better but does it come with any downsides? Inspired by a twitter post on using Any() and benchmarking it, I decided to run some of my own tests using BenchmarkDotNet.

The benchmarks that were run compare the use of these two methods, comparing enumerables and lists with two sizes, 1000 and 1000.
