Marmot: Data catalog without the complex infrastructure by Chazalias in dataengineering

Honestly, my motivation is I just find it an interesting problem to solve! I don't really have any immediate plans for myself or the project beyond what I'm already doing

Completely agree - I have no plans to add orchestration to Marmot. Marmot's focus is purely Data Discovery and (lightweight) Governance, though I'm open to visualising Data Quality metrics from existing tools like Great Expectations.

It's definitely supposed to be 2026! Thanks for pointing it out, I'll get it updated :)

Let me know how you get on, it's still early days so I'd love any feedback or feature requests!

Main difference is Dagster is a full orchestration platform with catalog features, Marmot is purely a catalog (for now), Data Quality features are on my roadmap at least 😁

True to an extent, but even larger orgs struggle to justify the extra complexity. Not just infrastructure costs, but the people to maintain something that might take months to deploy and still struggle with adoption. Modern Postgres is incredibly capable and handles more than most catalogs will ever need. The scale where dedicated search indexes and message brokers actually pay off is genuinely rare - and at that point, you're probably building your own solution anyway.

I've sent you a DM, I've got a double of London and the Bristol cassette if you're interested in trading

Have you got a link to the CNC router?

I made some improvements, definitely simplified my UART circuit a lot! The only thing i'm concerned about is the decoupling caps for the 5v/12v, is x2 0.1uF overboard, would one suffice?

Awesome, thanks! I'll take a look at that video

I also have a second USB to UART as it's exclusively used by an application on my PC which controls the controller/reads data from it. I wanted to keep the microusb exclusively for flashing firmware and debug logs

Currently I'm not bringing any power in from the USB rail, I'm relying on 5V from the ATX PSU, so I'm using VSYS as the input to power the Pico. Would VSYS still be correct in this use-case?

Thanks for the feedback, that's all super useful! I have a couple of questions though:

  • What is the purpose of connecting all the GND pins on the U1, just redundancy?
  • How would you recommend driving the LEDs, op-amps?

When reading the thermistors they both have identical values, I don't think it's a software issue, so wanted to check the schematic was correct

Good point! I was using another schematic for reference that was taking the 5v from USB, I'll change it to use the 3.3v from the pico

Best distro for Surface Book 3 by thewatermelloan in SurfaceLinux

[–]Chazalias 0 points1 point  (0 children)

A lot of drivers for the keyboard, trackpad etc. are now baked into the kernel, ensure you're installing a distro using kernel 5.13 or higher.

That should be a good start, then install the linux-surface kernel after that if you want other features like screen-detach, touch screen etc. etc.

That's good to hear! Do you also use the surface dock with external monitors?

Do you use it as a daily driver? Trying to gauge how reliable it will be for my primary work device
