Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Monitoring your logs is mostly a tarpit
Seems defeatist to me.
1) There has to be a notion that some things are worth acknowledging as "events"; this leads to the idea that what logs contain is indicators of events. It's a fundamentally philosophical notion. It means you need to take the time to decide what constitutes an event. Hearkening to machine learning and pirates, global warming may inversely correlate with pirates but that doesn't imply causation (either way): you can't just throw statistical techniques at data looking for "hits" and think that's significant. Even if you find some indicator as the article notes it could change; so you should identify some canary indicators and event those as well.
2) Which leads to the point about "bug parts": don't rely on a specific rare indicator, or the failure to identify such an indicator. If you find high-reliability indicators great, but look for other indicators which occur more often, that can be counted, and track those. For instance an indicator that e.g. systemd is restarting /something/, and that's happening more or less frequently, and correlates with a performance observable. If it stops reporting at all, you can start with the presumption that something about logging itself changed.
At this point my philosophical disagreement with centralized logging comes to the fore: it's expensive to load stuff into Splunk. I agree, and that's why I disagree with the approach and prefer federation.
You can use the Totalizer Agent (https://github.com/m3047/rkvdns_examples/tree/main/totalizer...) to increment counters in Redis for regex-identified keys. I don't care whether you use RKVDNS to retrieve the data or something else.

Ask HN: How do you monitor your systemd services?
In general this evolves to a SIEM-like solution in IT or gets added to the tag menagerie in OT.
If you're focused on "notifications are bad" note that notifications are push, and pull solutions are possible. Tail logs (or journalctl) and post significant events to Redis (https://github.com/m3047/rkvdns_examples/tree/main/totalizer...) for example.

How I keep myself Alive using Golang
Slightly related, but I've also been working on and off for a few years on my own Type 1 Diabetes management solution (https://github.com/algao1/iv3).
I haven't had time to work on it recently, but it uses ntfy (https://ntfy.sh/) to send alerts and such.
I was thinking of eventually incorporating some kind of automatic remedial solution eventually to help keep my glucose in range, but haven't had any time to look into it yet.

FBI using push notification tokens to identify anonymous users
If you go to the settings, there should be a notification category, which then contains another menu "App Notifications" where you can see all the apps that are allowed to receive notifications, but I don't know if this will stop google play services to receive these identifiers.
I use GrapheneOS, so I don't have any google play services running, but for the apps where I need notifications I use https://unifiedpush.org/ (only a few apps implement it) and I host my own https://ntfy.sh server.

Ask HN: What apps have you created for your own use?
Kind of similar, in the early days of COVID, I accidentally discovered that my state's website would have test results available several hours before they sent out the "view your results" email. So I made a script that would check the site every five or ten minutes and then ping me as soon as the result changed to something besides PENDING.
In the course of that I stumbled on https://ntfy.sh/ which solved the notification problem without needing Twitter, and I've used it since then to let me know when long-running scripts complete.

Governments spying on Apple, Google users through push notifications
I connect any app that supports https://unifiedpush.org/ to a self hosted https://ntfy.sh instance for fully self hosted push notifications

It's this time of the year again... which open-source project are you donating to?
changedetection.io just donated to the awesome crew over at ntfy.sh

2U Quiet & Efficient DIY Server Build
For further monitoring & alerting about critical cpu temperatures (unlikely now) for example, I plan to use notify & something else. Haven't thought about this much yet though.

Deno Cron
I've started tossing https://ntfy.sh/ alerts into my Deno apps to get push notifications for things I'm interested in
