macOS tool for tracking internet disconnections on a calendar heatmap
Hey everyone, I want to share a tool, UptimeLog, that helps track internet connections and identify patterns of disconnections and durations, all presented on a calendar heatmap (which I find to be a cool way to visualize different patterns and more). Originally, it started as a quick hack for Linux, allowing me to analyze patterns of periodic internet disconnections over time. However, I have since ported it to macOS, enabling cross-platform compatibility via making the monitoring dashboard accessible through a web page locally.

In plain words
UptimeLog is a macOS tool that monitors internet connectivity and logs disconnection events, displaying the data on a calendar heatmap to reveal patterns and trends. It tracks connection duration and outage frequency over time, helping users identify recurring issues. The tool runs locally and provides a web-based dashboard for viewing insights. Originally developed for Linux, it now works cross-platform on macOS.

Dayflow – A git log for your day2025 · github.com · ▲480Hi HN! I've been building Dayflow, a macOS app that automatically tracks what you're actually working on (not just which apps you have open). Here's what it does: - It creates a semantic timeline of your day; - It does it by understanding the content on your screen (with local or cloud VLMs); - This allows you to see exactly where your time went without any manual logging. Traditional time trackers tell you "3 hours in Chrome" which is not very helpful. Dayflow actually understands if you're reading documentation, debugging code, or scrolling HN. Instead of "Chrome: 3 hours", you get…

I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
