Analyzing Homepage Traffic

I’ve recently switched from using Lamdba@Edge to Cloudfront Functions as it was a better option for my use case. I’ve covered it briefly in this post.

Serial Communication via Software

Continuing from the last project (7-segment display device driver), I wanted to expand the project to use hardware interrupts. So, this project was aimed towards implementing a software approach to serial communication that is able to handle both transmission and receival (TX/RX).

Using Cloudfront Functions instead of Lambda

Recently, I had to upgrade the Node.js version on my AWS Lambda function. The function was a pretty simple URI parser which was needed for my homepage to add/remove file extensions to the requested URL. For example, when a user first visits thinkty.net/, they probably want to see my homepage which is actually thinkty.net/index.html and not the home directory. So, for those cases, a Lambda function (Lambda@Edge) would intervene and update the URI accordingly to ensure that the user sees what they want. To learn more about homepage setup using AWS tools, checkout my other post.

N7D - Linux Device Driver

Beginning my journey into embedded systems, I wanted to know how to make device drivers for Linux. I started with the Linux Device Drivers 3rd edition (available on LWN.net). Although the book is a little outdated, I highly recommend reading it as it has useful information about the concepts of the kernel, and various kernel level APIs & subsystems that are still used today.
