Using a Raspberry Pi to run GitHub Actions locally #RaspberryPi @nicolas_frankel

With his newly acquired Raspberry Pi, Nicolas Frankel explored executing GitHub Actions not on Google itself but on a dedicated machine (the Pi).

GitHub Actions comprise two components:

  • The GitHub Actions infrastructure itself. It hosts the scheduler of jobs.
  • Runners, which do run the jobs

By default, jobs run on GitHub’s runners. However, it’s possible to configure one’s job to run on other runners, whether on-premise or in the Cloud: these are called self-hosted runners.

The process can be non-trivial but the blog post goes over the procedures.

Conclusion: Migrating from a GitHub runner to a self-hosted runner is not a big deal but requires changing some bits and pieces. Most importantly, you need to understand the script runs on the machine. This means you need to automate the provisioning of a new machine in the case of crashes. I’m considering the benefits of running the runner inside a container on the Pi to roll back to my previous steps.

Buffalo’s Black Arts Community #ArtTuesday

When you think of hubs for Black art and artists, Buffalo may not be on your list. It should be! Buffalo has a long, rich, and diverse history. Hyperallergic shares how Black artists created space and community in Buffalo.

As a curator, writer, and artist, my work is grounded in storytelling. Contextualizing the work of artists past and present for broad audiences is an incredible responsibility; arts administrators play a significant role in determining whose stories are preserved in history and how they are remembered. But what about the stories that aren’t told? How can narratives historically excluded from the canon be elevated and recognized for their enduring influence?

The Many Colors of Atelir Sisu’s “Elysian Arcs” #ArtTuesday

Double rainbow? All the way? Triple rainbow even? There’s even more prismatic excellent to be found in the workd of Atelier Sisu’s installation in London. Here’s more from COLOSSAL:

“Elysian Arcs” is part of RECHARGE 2024, an initiative responding to concerning trends in the mental health of London’s young professionals. Following the duo’s installation titled “Evanescent” in the same location last year, the new iteration incorporates the playfulness of their self-described “bubble-tecture” along with rainbow-like arches that gleam with a pastel sheen.

During the past year, Larriviere and Pasfield have been exploring the possibilities of dichroic materials and curvatures, which lends the iridescence evocative of soap bubbles. The surface of “Elysian Arcs” is designed to allow light to move across both the external and internal surfaces in a way that produces the greatest array of colors, which shift as one moves around or through the piece.

An improved graphic pattern generator #ArtTuesday #Art

The Lucky Resistor blog posts version 2.6 of their Circle Pattern Generator. While the original could do complex patterns of circles, later versions have varied shapes to riff on.

The new version has a shape browser window for picking the initial shape

and new algorithms for different shape arrangements.

It runs on macOS and Windows 64 bit.

LogicAnalyzer: a Raspberry Pi Pico-based 24 channel logic analyzer

Agustín Gimenez Bernad leads development of LogicAnalyzer, an inexpensive 24 channel logic analyzer with 100Msps, 32k samples deep, edge triggers and pattern triggers.

LogicAnalyzer is a very cheap analyzer based on a Raspberry Pico (or Pico W). The analyzer offers up to 24 digital channels, pre and post trigger sampling, edge trigger and pattern trigger up to 16 bits.

Additionally to the hardware the logic analyzer also includes a powerful software (Windows only for now) where you can visualize the captured data, export captures, use protocol analyzers, etc.

The latest version (5.0) adds Burst mode. With burst mode you can capture blocks of data and the analyzer will rearm itself immediately and capture more data when the trigger condition is met again.

Check out the details, code, and boards in the GitHub repo here.

Corollaria Branch for MIT #Art @nervous_system

The MIT Morningside Academy for Design invited Nervous System co-founders, MIT alumna Jessica Rosenkrantz ’05 and Jesse Louis-Rosenberg, to offer a week-long workshop at MIT exploring design and computation. “Building Complex Curvature from Flat Sheets” involved 15 MIT students in making a large aluminum sculpture now displayed on campus.

Participants constructed surfaces with complex curvature from flat materials like paper, wood, or metal. Normally, flat sheets can only bend in one direction making so called ‘developable’ surfaces with zero Gaussian curvature. They used custom computational design tools to contort these materials into highly curved surfaces without any forming or creasing. They learned how tools work, designed some demo parts, and constructed a large sculpture using these techniques as a group.

The sculpture was constructed from dozens of laser cut panels connected by rivets which we were cut, finished, assembled, and then installed on campus.
