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.

Web Scraping in Python – The Complete Guide
I strongly recommend adding Playwright to your set of tools for Python web scraping. It's by far the most powerful and best designed browser automation tool I've ever worked with.
I use it for my shot-scraper CLI tool: https://shot-scraper.datasette.io/ - which lets you scrape web pages directly from the command line by running JavaScript against pages to extract JSON data: https://shot-scraper.datasette.io/en/stable/javascript.html

Don’t Build a General Purpose API to Power Your Own Front End (2021)
This is exactly what the `Accept` HTTP header is for https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Ac...
I think the author is generally correct that all JSON should be provided in a single request, but if you want to prove it, then you should be able to change your accept header to and from `application/json`/`text/html seeing nearly identical data.
In fact, this is what both GitLab and Github do. Try it out!
`curl -L https://github.com/simonw/shot-scraper` (text/html)
`curl --header "Accept: application/json" -L https://github.com/simonw/shot-scraper` (application/json)

Git scraping: track changes over time by scraping to a Git repository
Git is a key technology in this approach, because the value you get out of this form of scraping is the commit history - it's a way of turning a static source of information into a record of how that information changed over time.
I think it's fine to use the term "scraping" to refer to downloading a JSON file.
These days an increasing number of websites work by serving up JSON which is then turned into HTML by a client-side JavaScript app. The JSON often isn't a formally documented API, but you can grab it directly to avoid the extra step of processing the HTML.
I do run Git scrapers that process HTML as well. A couple of examples:
scrape-san-mateo-fire-dispatch https://github.com/simonw/scrape-san-mateo-fire-dispatch scrapes the HTML from http://www.firedispatch.com/iPhoneActiveIncident.asp?Agency=... and records both the original HTML and converted JSON in the repository.
scrape-hacker-news-by-domain https://github.com/simonw/scrape-hacker-news-by-domain uses my https://shot-scraper.datasette.io/ browser automation tool to convert an HTML page on Hacker News into JSON and save that to the repo. I wrote more about how that works here: https://simonwillison.net/2022/Dec/2/datasette-write-api/

Ask HN: Small scripts, hacks and automations you're proud of?
I have a neat Hacker News scraping setup that I'm really pleased with.
The problem: I want to know when content from one of my sites is submitted to Hacker News, and keep track of the points and comments over time. I also want to be alerted when it happens.
Solution: https://github.com/simonw/scrape-hacker-news-by-domain/
This repo does a LOT of things.
It's an implementation of my Git scraping pattern - https://simonwillison.net/2020/Oct/9/git-scraping/ - in that it runs a script once an hour to check for more content.
It scrapes https://news.ycombinator.com/from?site=simonwillison.net (scraping the HTML because this particular feature isn't supported by the Hacker News API) using shot-scraper - a tool I built for command-line browser automation: https://shot-scraper.datasette.io/
The scraper works by running this JavaScript against the page and recording the resulting JSON to the Git repository: https://github.com/simonw/scrape-hacker-news-by-domain/blob/...
That solves the "monitor and record any changes" bit.
But... I want alerts when my content shows up.
I solve that using three more tools I built: https://datasette.io/ and https://datasette.io/plugins/datasette-atom and https://datasette.cloud/
This script here runs to push the latest scraped JSON to my SQLite database hosted using my in-development SaaS platform, Datasette Cloud: https://github.com/simonw/scrape-hacker-news-by-domain/blob/...
I defined this SQL view https://simon.datasette.cloud/data/hacker_news_posts_atom which shows the latest data in the format required by the datasette-atom plugin.
Which means I can subscribe to the resulting Atom feed (add .atom to that URL) in NetNewsWire and get alerted when my content shows up on Hacker News!
I wrote a bit more about how this all works here: https://simonwillison.net/2022/Dec/2/datasette-write-api/

Show HN: I built a self-hosted status page and monitoring tool for my projects
Hey mate, I'm using https://healthchecks.io/ for heartbeat monitoring my crons. It's been working flawlessly for quite some time now. The UI is super clean and easy to navigate. It's also free up to 20 monitored jobs. Note - I'm not in any way related to that project.

Webhooks suck, but here are alternatives
In fact, your platform (https://healthchecks.io/) is a prime example of where running customer wasm would be really excellent.
Instead of sending webhooks out to customer configured URLs, you could run a Wasm environment to execute customer code. Off hand, a good use case here is to do further inspection of the event before it gets sent off to some other system - maybe there are cases where you send false-positives and needlessly trigger external system alerts. The customer Wasm could do more introspection on the healthcheck event and make a more informed decision about how to proceed.

i use healthchecks.io and have been very happy

Prioritize IPv4 over IPv6 in dual stack
Because of this block on the router, and the fact that IPv6 connections are by default preferred over IPv4, many things on the system now cannot access the internet. the only things that can access the internet are for accessing servers that ONLY support IPv4 like my mail.smpt2go or my uptime monitoring scripts for healthchecks.io.

Managing re-occurring tasks - Daily/weekly/monthly
We use a heartbeat system. Basically the monitoring continuously sends an alert to a healtcheck system. If that heartbeat fails, PagerDuty sends an alert to the oncall.
