azonenberg: I've vaguely figured out cmake now
<bluezinc_>
now things are failing for even more esoteric reasons
<bluezinc_>
azonenberg: is getting Render error 506 a common issue?
<bluezinc_>
looks like there's some incomplete/invalid FBO, which leads to a GL_INVALID_OPERATION, and then a bunch of GL_INVALID_FRAMEBUFFER_OPERATION
<azonenberg>
There is a known bug that i have not yet tracked down, which occurs when you move a waveform to a new viewport at unpredictable intervals
<azonenberg>
is that what you were doing?
<azonenberg>
it happens maybe one in ten times i do it and i havent yet found a reproducible trigger or cause
<azonenberg>
In other news, i experiented a bit with the carbon paint
<azonenberg>
it can be thinned with acetone, but getting reproducible thickness is nontrivial
<azonenberg>
if you put it on full strength with a swab it tends to cake and crack
<azonenberg>
It was just kind of a side experiment, the new pcb at fab is the main line of research re probes right now
<bluezinc_>
carbon film isn't fun to work with (even for the professional board shops)
<bluezinc_>
azonenberg: so it looks like there's a lot of errors happening around resize 4 in WaveformArea::on_resie
<bluezinc_>
,s/resie/resize/
<bluezinc_>
and then on_render fails the sanity check at the end
<bluezinc_>
and a large portion of the display is black
<bluezinc_>
I'm just launching this - not doing anything fancy with moving viewports or any of that
<azonenberg>
bluezinc_: yeah i was experimenting with seeing if i could make a resistor with lower parasitics

S2P captured by my tool (using PC USB <=> GPIB HP8753D) and displayed with Smith V4.1
<bvernoux>
it is just a basic attenuator characterized with a very good VNA
<bvernoux>
and my S2P are not far from the reference
<bvernoux>
even without the final calibration kit as I have not entered the CAL KIT details and I'm using female load + male-male adapter instead of male load (as I shall receive it soon with some spare RP-SMA adapters ...)
