@spacetelescope definitely worth clicking through: the image holds a second discovery that’s easier to overlook. Examine the white elliptical galaxy at left. A faint red arc appears in the inset at 10 o’clock. This is a very distant galaxy whose light is bent by the gravity of the elliptical foreground galaxy – and its appearance is duplicated. The stretched red arc is warped where it reappears – as a dot – at 4 o’clock. These images of the lensed galaxy are so faint and so red that they went unrecognized in Hubble data, but are unmistakable in Webb’s near-infrared image.

i.e. for example handles base64 encoding/decoding for handling binary blobs within JSON automatically, or it helps you with dealing with JSON's >53bit integer problem, and various other things.

Right now, documentation for sd-varlink and sd-json is scarce (one could even say "barely existing"), but there are plenty of real-life examples in the systemd source tree, of course.

Had fun in at #OSSSummit in Tokyo yesterday demonstrating a TPM interposer attack obtaining the systemd cryptenroll boot keys

And also explaining how the new Linux Kernel TPM patches can help defeat this

For those who asked, my python3 interposer designed to steal the keys is here:
