My understanding is Surface Linux is mostly the project built around developing kernel patches to be upstreamed, so the specific Kernel is more focused around external patches. Here’s their comment on this from their GitHub [0]:

We aim to send all the changes we make here upstream, but this may take time. This kernel allows us to ship new features faster, as we do not have to adhere to the upstream release schedule (and, for better or worse, code standards). We also rely on it to test and prototype patches before sending them upstream, which is crucial because we maintainers cannot test on all Surface devices (which also means we may break things along the way).

So should you install this custom kernel and the associated packages? It depends: We generally recommend you try your standard distribution kernel first. If that works well for you, great! But if you're missing any features or experiencing issues, take a look at our feature matrix and give our kernel and packages a try. If your device is not listed as supported yet, feel free to open an issue.

In Accelerando by Charles Stross, the fictional venture altruist Manfred Macx "...patented using genetic algorithms to patent everything they can permutate from an initial description of a problem domain - not just a better mousetrap, but the set of all possible mousetraps."

Looks like we may not get the set of all possible mousetraps.

GPS 5 years ago

GPS applies the theory of relativity directly to your everyday life... pretty cool!

RUAG makes most of the "payload adapters" that integrate the satellite onto the top of a rocket. Based on the size of JWST they're probably using a 1666 model payload adapter.

RUAG's clamp-bands and separation system have a very well characterized Shock Response Spectrum [0, pg. 4], which would have been accounted for in the design of JWST. But the spacecraft and satellite usually separate after the initial shock of the explosive bolt and clamp-band de-tensioning, so they may need to investigate any coupling or recontact of the clamp-band.

If we're lucky they had some accelerometers running during integration and can review actual response data.
