in thread BEGIN block and failure to initialize constants

Oh man, I was overthinking this problem way too much. For some reason I thought constants were a special case and forgot entirely about use's equivalence to a BEGIN block as you just described.

Thanks for dusting that knowledge off for me kennethk.

Also, cool note about nesting those blocks, TIL. =)

Strange things are afoot at the Circle-K.

[Corion]: GrandFather: Ah, (hardware) APIs - I have a similar situation with Chrome and its API... It is fairly underdocumented and I guess I have to hunt...
[Corion]: ... down supposedly working code to find out what I'm supposed to do
[GrandFather]: I haven't any "working code" to inspect! I have to find ways to generate reference signals then check the numbers I get at the far end match.
[GrandFather]: That's ok when the signal is a voltage, but there are three axis accelerometers, gyroscopes and magnetometers in these things! A little invention is needed at times!
[Corion]: GrandFather: Yeah, in that aspect, hardware is far more a black box than software
[GrandFather]: Oh, and the manufacturer tells lies too! I'm sure they don't mean to, but I know for sure some of the stuff they say is just wrong. It's possible they don't understand what we are asking, but that's not a good look either
[Corion]: GrandFather: Ah, unit testing hardware is fun, especially when the hardware is uncalibrated ...
[GrandFather]: Us: "What scaling do we need to apply to the numbers from the SDK for the wibble?". Them: "Oh, the numbers from the SDK for the wibble are already correct, they don't need scaling"
[GrandFather]: In our code: wibble range 1 scale by 1, range 2 scale by 2, range 3 scale by 4, range 4 scale by 8
