Kind of a weekend project:
I want to control an RGB LED strip (GS8208) from a Raspberry Pi by abusing SPI to send the data signal it expects (return-to-zero) using , but it's not working. I have no idea how to debug it other than with an oscilloscope I don't have.
Maybe the buspirate I have can help?
Help and feedback welcome :)

@minus I use my own format which is not standard but is slightly more human-readable and fail-safe:
It's still year-month-day, and the month name is always the same for a given month number, so it still sorts lexicographically, but it also reminds yyyy-dd-mm people that they're wrong
Today I went 'fuck you, hibernate' and rewrote the whole logic of an REST API function in SQL (~80 lines).
Select with recursive CTE and it needed a recursive CTE for each of the results of the select too. So i put that in a function. It's now a couple times faster and also more correct.
Previously it was a fetch of a list and a cascade of additional calls in java to fetch more data (implicit through lazy loading and explicit via calls to services).
Don't do recursive data structures in your RDBMS, kids.
Also, lazy loading is the spawn of the devil.

The project needs additional "tile delivery servers" in the region to cope with the load, more details on the requirements here:
