No pillaging so far.

I'll be offline a while. Hopefully we'll have time for some raiding and pillaging along the way.

I just learned a new technique to compute the hypotenuse of a right triangle (if you don't have a P scale) from these cryptic markings on the back of a Crestel slide rule!
Set the cursor on the y, the larger of the sides on D, slide the B so that 10 is aligned with it, then slide the cursor to x, the smaller of the sides on D. Read the value n on B and set the cursor to 10+n on B. The sqrt(x^2+y^2) is now indicated on D.
(Although does this only work if x and y have the same exponent?)

Also surprisingly, the Crestel slide rule *has* a P rule that allows the computation of b=c*sqrt(1-(a/c)^2)

I guess that explains why many of the lines weren't being plotted correctly.

my keyboard is getting a bath for its thirty-eighth birthday.

@azonenberg have you seen this one weird trick to reduce the number of vias in your PCB design?

@jwz what do you have against "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; PalmSource/hspr-H102; Blazer/4.0)" or "Opera/9.80 (J2ME/MIDP; Opera Mini/4.0.9800/191.379; U; en) Presto/2.12.423 Version/12.16" ?

Almost got pounced upon!

"Average user has two X1 Carbons" factoid is a statistical error. Thinkpad Georg who hacks on firmware and sleeps on a bed made of bricked laptops is an outlier and should not have been counted.

Following up on the original question... Concise Products in Japan seems to still be producing circular slide rules https://www.sliderule.tokyo/products/detail.php?product_id=7

The combined Latitude, Declination, LHA grid didn't work, so instead I've added the normal S/ST, and T/T1/T2 scales to allow computation of Hc and Z from the corrected sextant height.

Printed and laminated a prototype of my solar slide rule on 350g A3 at the local print shop and it works fairly well! Correcting sextant height for index error, temperature, refraction, height of eye and lower limb is fast, as is computing latitude from the noon sight. Computing Hc and Z is a bit more involved (using additional scales on the reverse side)

Using a nuke to take down a blimp seems like overkill, but it's the only way to be sure.
