Using Encrypted DNS to Prevent Tracking on macOS
Using encrypted DNS is one less way that you can be tracked, and some countries block certain websites through DNS. You can set up your Mac to use encrypted DNS, but you have to install a profile to set it up. A popular profile is this open-source one on GitHub. These profiles also work on iPhones and iPads. I have installed one of the “Cloudflare 1.1.1.1” configurations. The web page gives you installation instructions.
Health And Calorie Tracking Apps I’ve tried
For years I’ve been interested in what was called the “quantified self” space and so I’ve been using apps to track simple bio markers. I even managed the migration of a 13TB database and application migration to the cloud for the AI Vitality Hong Kong tracking app. Wanted to make a list of what I have tried and what I’m using for reference:
Tried but didn’t stick
- Bevel – Was recommended by a friend and tried it for workouts. It seems to be a real “super app”, but I’m not sure why it didn’t stick. I think it was sending me a lot of initial notifications.
- Cal.ai – Tried this one because I heard the first interview from the founder on My First Million Podcast, and what seemed to be a short time after I heard the second interview about how he had a huge exit.
- OpenNutrition – Caught my eye because they have published their nutrition database online that can be downloaded.
Currently Using
- Oura – Been using this app and the ring for like 7 years and really love the design. Check it for my sleep daily and sometimes remember to record my meals here.
- Withings – Using this to take my blood pressure and weigh myself on their scale every day.
- SleepCycle – Monitoring my snoring with this app.
- Fud AI – Open-source calorie tracker written in Swift and Kotlin, just installed and will play around because it lets you bring your own AI key.
Heard about but Haven’t tried
Just heard about these but haven’t tried them noting them in case I would like to come back to them.
AI Follows List on X
I started to put the accounts related to AI that show up own my X feed into an X list. These are the ones that I think are worth following that are either building in the industry or are thought leaders.
Bootleg concert recordings
The Internet Archive digitized one guys bootleg concert recordings. He donated over 10,000 tracks with ~2,500 digitized. I’m listening to Nick Cave and The Bad Seeds Live from 1986 as I write this.

Dark things might be happening on your home network
People are buying expensive streaming boxes from China that are compromising their network. The entity behind it even has a network of people that could be in your neighborhood who are resellers. Even though they give you free streaming, they can be listening on your network to capture your passwords and other information. Listen to the podcast to protect yourself.
