Yeah, I was just trying to keep to the letter of what you'd said - you asked for it just to use OpenGL/GLFW bindings, not other libraries, so I didn't want to install cl-opengl and cl-glfw, and told it just to use its own FFI.

In their own first example of English text rendering, it's mistakenly rendered "The silent patient" as "The silent Patient", "The night circus" as "The night Circus", and miskerned "When stars are scattered" as "When stars are sca t t e r e d".

The example further down has "down" not "dawn" in the poem.

For these to be their hero image examples, they're fairly poor; I know it's a significant improvement vs. many of the other current offerings, but it's clear the bar is still being set very low.

This article is literally the reason why people crave summary, because it was so content-free that it was a waste of my time to have read it all. It was a lecture extolling the virtues of repetition while simultaneously displaying none of them.

RFC1459, the IRC one. I wrote the QuakeNet channel services once upon a time.

Yeah, it’s as if they wrote a program to calculate pi in a float and saved the output. Very strange choice given how many places the value of pi can be found.

Childhood exposure to pi generation algorithms; the correct version above was from memory.

Even your example of discharging a capacitor can end up with a pulse both directions, caused by the inductance of the wires.

In this specific situation, there's no common reference level, and so the induced pulse will go both directions. You can think of this as being about the edges of the pulse being the parts that actually cause radio to be transmitted, and there's both a positive-going edge and a negative-going edge on a pulse.

Sign matters as well as magnitude. The pulse created will have both a positive and negative part - waveform sort of like --^v-- and so you can get either direction bit flip. It's not equivalent to connecting a battery to the pin; EMI's more like AC in that it goes both directions.

Thanks for the suggestions - I'll definitely have a poke at it in TDR mode, that's a good plan.

Thanks also for the scikit-rf driver - I've an 8753ES as well, and I've used scikit-rf with that, but not yet with the 8510.

One of the few places you run into fellow 8510C users. How stable do you find your calibration on the 50GHz 83650 setup? My 20GHz one with the 8341B is very, very, very drifty for the first couple of hours after powerup (i.e. a good load goes from -60dB to about -15dB half an hour after calibration), but I'm not sure whether it's normal or something up.

A dissenting opinion on the design - for me, this presentation was like watching a video to find information; too slow paced, and it made me impatient the whole time. The original notebook format was far better in that regard. The layout within each section is beautiful, but the animation and the scroll-sensitive layout (vs. just having a series of static diagrams) makes it unpleasant for me to read.

The content's excellent and it was fascinating to see how the differences between characters and karts play out though!
