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.

Ask HN: What's the coolest physical thing you've made?
I made a rotary input device that provides software-defined "virtual" detents and end-stops, implemented using a BLDC gimbal motor. It can dynamically switch from completely smooth unbounded rotation, to having detents with configurable spacing and strength and "end-stops" that spring back if you try to rotate past them.

It's got a round LCD on the front of the knob (wired and supported via the hollow shaft of the motor) and uses the flex of the PCB and strain gauge sensors (in the latest revision, simply SMD resistors whose resistance changes when stretched) to detect when the knob is pressed down.
It's open source hardware and software - https://github.com/scottbez1/smartknob
HN folks might appreciate that it communicates with host software on the computer via protobuf-encoded USB serial messages -- nanopb is awesome for embedded C protobuf support, and having the defined schema, autogenerated serialization code, and compile-time type safety is so much nicer than ArduinoJson or hand-written binary protocols!
I'd love to get it hooked up to some real software eventually (video editors or home-assistant control are my 2 main ideas), but it's really just been a fun project to tinker with and try out some new ideas and parts I've never used before.

Help with MT6701/SSI
I'm trying to design a smartknob based off Scottbez1's design (https://github.com/scottbez1/smartknob), but with a stripped down feature set. However I can't seem to get the magnetic sensor to work properly - it's an MT6701 connected to an ESP32 via SSI.

Is this rotary encoder an adafruit exclusive?
Thank you so, so much for finding it. Unfortunately on eBay its not cheaper and ali doesn't have it cheaper either. It looks like an out of production item, like when I wanted to make this https://github.com/scottbez1/smartknob and it was gone except when sparkfun got a few.

Ask HN: Any tool for managing large and variable command lines?
In addition, I think bash's `operate-and-get-next` can be very helpful. When you go back through your shell history, you can hit Ctrl+o instead of enter and it will execute the command then put the next one in your history on the command line, and keep track of where you are in your history. This way, you can rerun a bunch of commands by going to the first one and Ctrl+o till you are done. And you can edit those commands and hit Ctrl+o and still go to the next previously run command.
Note: fzf's history search feature breaks this. https://github.com/junegunn/fzf/issues/2399

So You Think You Know Git – Git Tips and Tricks by Scott Chacon
Those are the most used aliases in my gitconfig.
"git fza" shows a list of modified/new files in an fzf window, and you can select each file with tab plus arrow keys. When you hit enter, those files are fed into "git add". Needs fzf: https://github.com/junegunn/fzf
"git gone" removes local branches that don't exist on the remote.
"git root" prints out the root of the repo. You can alias it to "cd $(git root)", and zip back to the repo root from a deep directory structure. This one is less useful now for me since I started using zoxide to jump around. https://github.com/ajeetdsouza/zoxide

Which command did you run 1731 days ago?
> my history is so noisy I had to find another way
The fzf search syntax can help, if you become familiar with it. It is also supported in atuin [2].

Z – Jump Around
You call it with `n` and get an interactive fuzzy search for your directories. If you do `n ` instead, it’ll start the find with `` already filled in (and if there’s only one match, jump to it directly). The `ls` is optional but I find that I like having the contents visible as soon as I change a directory.
I’m also including iCloud Drive but excluding the Library directory as that is too noisy. I have a separate `nl` function which searches just inside `~/Library` for when I need it, as well as other specialised `n` functions that search inside specific places that I need a lot.

Fish shell 3.7.0: last release branch before the full Rust rewrite
I do find the history pager stuff interesting, but ultimately not of tremendous use for me. I rebound all my history search stuff to use fzf[1] (via a fish plugin for such[2]), and so haven't been aware of the issues
