As near as i can tell this is very cool.

Most variable pitch propellers use a swashplate (helicopters) or just a collective yoke (also helicopters, and acrobatic planes).

If I understand what op has done is to print a propeller with NO FIXED LINKAGE to control the propeller pitch, but instead lead or follow the inertia of the propeller by rapidly-adjusted motor rpm to induce variation in the angle of attack of the propeller.

In my first job, grumpy Martin had as one of his many indispensable tasks, to build cmucl. (Itasoftware, one of the main lisp shops of the age)

It seems to me that this should have been a case of steganography?

Instead of wiping it clean, wipe to innocuous mode. Then the burden on their part is not only to show that I gave a bad pun, but that the innocuous mode is materially different than the previous state.

Pilot lights are often designed so that the heat from the flame holds a bimetallic switch in the open position. Should the light go out, the bimetallic switch will shut as it cools.

Exposing my ignorance, how is this very different from copilot or other online coding agents?

20 trucks lined up in our street (not the real name because it is much too far away to check) remains forever in our bookcase.

I’m confused and think I don’t get it.

If a webpage is an iceberg, the buttons and menus and dropdowns are the visible part. If I understand this page object, that’s what he proposes testing.

But the bit I care about is the bit underneath that will compose REST calls from those UI elements and sometimes make subsequent REST calls from the result of the previous ones.

That is the tricky bit to test, and the bit where we *still* fall back to manual testing and recorded demos for qa.

I was hoping this was a suggestion for a better selenium.

I was a bit frustrated that the expected precision wasn’t on the main summary screen.

Does anyone know?

I feel like I missed a preread that teaches me about these strangle super-numeric ip addresses. Eg 400.564.987.500

Am I just seeing ipv6 in an unusually familiar format? Or is it an intentionally malformed format used by wireguard for internal routing?

Same way you get it in a quadcopter. You increase rpm in the (say) clockwise rotating props and decrease it in the counter clockwise rotors.

Net effect is yaw counter clockwise, but zero net change in lift.

I’m curious about the control surfaces. Since you have the four quadcopter motors, you could potentially just induce all three of yaw pitch and roll by powering those up.

I wonder if the reduction in weight from the now unneeded servos would pay for the extra battery drain.
