How to See Where Python Site Package are Installed on macOS

Recently I had a question come in from a reader on how to determine where the site packages are installed on macOS Mojave. So, what I wanted to do was create a short video explaining how to find these site packages and how to see what packages are installed. This technique should be applicable on macOS Mojave or High Sierra both. First, let's understand why you would want to know where the site packages are installed on any system? The main reason would be for making development decisions about how to design you Python program. This can be especially valuable for knowing which site pac

How to Use the Python asyncio Library

Submitted by matt_eaton on Tue, 01/29/2019 - 11:48 AM

Python 3 has an excellent library called asyncio that can be used for writing concurrent code on anything from web-servers, to databases, and even distributed task queues. Asyncio is created from a non-blocking programming model that provides your program the flexibility to delegate data when it is available as instead to waiting for data to be received. This prevents code in your program from getting bottle-necked and allows data tasks to be run concurrently to get greater performance and processing from your program's I/O. On

TCPdump is one of my favorite network packet analysis tools in existence today. In the past year I have enjoyed TCPdump so much that I have wanted to learn more about the project.

My contributions are not much, but they help me learn the ins and outs of the project and how to use some of the more advanced features as I come up in issues or pull requests. During my time thus far I have noticed that a lot o

Now that these goals have been achieved the Swift community is widening it's support to working with dynamic languages such as Python, Ruby, JavaScript, and Perl in Swift 4.2's language addition for

Over the last 6 months I have noticed a lot of code going into CPython working with SSL and TLS. At first I did not think anything commits and brushed it off as bug fixes and improvements. However, as the months went by and I kept seeing these commits come through it started to get my curiosity piqued about what might be happening in language under the hood.
