entr VS rerun

entr ("Event Notify Test Runner"; GitHub), is a command-line tool written by Eric Radman that allows running arbitrary commands whenever files change.

I use something very similar on https://lunar.fyi and https://lowtechguys.com but I wouldn’t call this “simple” anymore.

They use Jinja templating, I prefer Slim (https://github.com/slim-template/slim#syntax-example) which has a more Pythonic syntax (there is plim [0] in Python for that)

I use Tailwind as well for terse styling and fast experimentation (allows me to write a darkMode-aware and responsive 100 line CSS in a single line with about 10 classes)

For interaction I can write CoffeeScript directly in the page [1] and have it compiled by plim.

I run a Caddy static server [2] and use Syncthing [3] to have every file save deployed instantly to my Hetzner server.

I use entr [4] and livereloadx [5] to rebuild the pages and do hot reload on file save. All the commands are managed in a simple Makefile [6]

You can already see how the footnotes take up a large chunk of this comment, this is not my idea of simple. Sure, the end result is readable static HTML and I never have to fight obscure React errors, but it’s a high effort setup for starters.

Simple for me would be: write markdown files for pages, a simple CSS for general styling (should be optional), click to deploy on my domain. Images should automatically be resized to multiple sizes and optimized, videos re-encoded for smaller filesize etc.

I have mostly implemented that for myself (https://notes.alinpanaitiu.com/How%20I%20write%20this%20blog...) but it feels fragile. I’d rather pay for a professional solution.

Try entr for fast reloading. Another one is hupper.

Maybe the folks at Rerun [1] know something about it? I imagine at least some of their customers are Rust robotics shops.

Full release notes: https://github.com/rerun-io/rerun/blob/main/CHANGELOG.md

No specific support for audio embeddings yet, though depending on you're specific use-case, you might be able to map your data to more generic primitives such a TimeSeriesScalar, LineStrips2D, BarChart, or Tensor.

We have an open issue for adding more support for audio-based projects -- if you have specific needs feel free to add a comment: https://github.com/rerun-io/rerun/issues/2852

https://github.com/rerun-io/rerun is such a great tool for creating interactive dashboards to look at real-time data. Curious if there are others looking for something like this and what the other use cases would be interesting. I have heard ideas like:

egui's lead author is using it for his computer vision startup.

To test the power draw, I conducted an unscientific experiment by circling the cursor over both a GTK4 app (GNOME Console) and an egui app (Rerun Viewer), while monitoring the CPU/GPU utilization and stabilized power draw with PowerTOP. The results indicated that when circling the cursor over the GTK4 app, the CPU/GPU usage was nearly negligible, and the stabilized power draw was around 13 W. In contrast, when circling the cursor over the egui app, the CPU/GPU usage was considerably higher, resulting in a stabilized power draw of around 21 W. This amounts to an increase of approximately 60%. Taking into account a power draw of around 10 W when doing nothing at all, the increase becomes roughly 260%. I also tried the same experiment with Iced, and while the increase was not as extreme, it still utilized resources when circling the cursor over a blank surface.
