👋 Hi, I’m Tom.

Using socat, Linux traffic control (tc) and netem, we can emulate realistic satellite link network conditions. The great thing about this approach is that it’s completely portable - you can drop it in front of any service without modifying the target application. Overview Realistic Network Emulation: Simulate various satellite scenarios from LEO to GEO Real-time Monitoring: Expose metrics via Prometheus and visualize in Grafana Runtime Control: Change network conditions on the fly Portable Proxy Design: Drop-in containerized solution that works with any service Technical Implementation Here’s how to build a network emulator using common Linux tools and containers:...

I built a conversational AI using LangChain and the OpenAI API that analyzes Facebook Messenger data. This enables you to have meaningful conversations with your historical chat data. Here’s a quick walkthrough of the process and some insights.

Cobra is a library for creating CLI applications in Go. It provides a simple interface for defining commands, flags, and subcommands. I’ve utilized Cobra to create a CLI tool and organized the code into multiple packages. Find the related source code here: https://github.com/m7kvqbe1/advent-of-code-2023 Init First we initialize the project as a new module: go mod init github.com/m7kvqbe1/advent-of-code-2023 This creates a go.mod file (there is also go.sum file which is essentially a lockfile)....

A small program in Go for polling and scraping ticket websites then sending SMS messages when resale tickets become available. This was a learning exercise in Go concurrency: goroutines, channels, wait groups etc. Find the related source code here: https://github.com/m7kvqbe1/go-ticket-polling Overview Polling and Scraping: Uses the colly web scraping library to poll a site and search for the availability of resale tickets. SMS Notification: When tickets are found, sends an SMS to the specified phone numbers using the Textbelt API....

Recently, I explored Unix Sockets and Protobuf with Go. Here’s a brief overview of some of the things I learned. Find the related source code here: https://github.com/m7kvqbe1/unix-sockets-protobuf-play Unix Sockets: Inter-Process Communication Unix Sockets offer a method for inter-process communication (IPC) on the same machine. It’s faster and leaner than leveraging a network protocol like TCP. They’re straightforward to set up in Go: listener, _ := net.Listen("unix", "/tmp/example.sock") conn, _ := net....
