I explored building a neural network in Python - with no libs, in order to really build an intuitive understanding of how it all works. I found it super fun, and even included an interactive notebook at the end you can play with on your own.
Enjoy!

A Simple Neural Network from Scratch
In this post, we’ll explore building a neural network from scratch, for whatever definition of “from scratch” includes the use of Python. This means no third-party libraries like PyTorch, Tensorflow, ...

📢 [NEW POST] 📢 In today's post I explore Unix Domain Sockets - these are sometimes an overlooked capability for inter-service communication with some really unique features, and will be the foundation for blog posts I aim to write in the near future.
Enjoy! 😄

Unix Domain Sockets
In a previous post on sockets in Linux we briefly explored Unix Domain Sockets (UDS) by invoking the AF_UNIX domain in a few examples. In this post I’d like to dig into more of the specifics of using ...

Linux Sockets: Relevant Syscalls
In my previous post on Linux sockets, there were several examples that referenced “syscalls” when working with sockets. I’d like to spend a little time exploring these more exhaustively - what they ar...

Linux Sockets: Domains and Types
The socket is one of the most crucial primitives for systems communication. It is the endpoint on which an application can send and/or receive information, either between processes on the same system,...
