No argument there. I took engineering in college, not accounting. I hire bookkeepers. I haven't done a tax return or balanced a checkbook in 30 years.
I've used spreadsheets (a long time ago) and decided that they are dumb and dangerous. I write programs, or get other people to write programs. Or use Spice. I mostly design electronics. That's supposed to be our topic here.
LT Spice can do useful math, and graph things, and you do control execution order. The "program" is a lot more visible, and can be better commented, than a spreadsheet.
My production people use spreadsheets, but mostly for record keeping.

No way I'd ever let Windows run a Linux VM on any hardware I own! Just
*maybe* the other way round, perhaps. MAYBE.

Or you could use the "Goal Seek" function, that's what it is there for. Create an input cell with an initial guess and a formula cell that does something with the input cell, select Goal Seek from the menu (or find it lost in a ribbon, if you can, I hate that UI), tell it the input cell and the output cell and the target output value, and it will iterate changing the input until it gets the desired output.

I never said a goddamned thing about powerpoint.
My production line travellers and test data sheets are the hard copy requisites some military and many commercial contracts carry. Upon some of those pages are blank plot diagrams where the UUT data is recorded by the technician, in real time.

I wonder if I can get it to do various depth mandelbrot array calculations.
This bash script is the best one I have seen for the command line.
Posted here only a couple of these lines wrapped so give it a once over before you try to run it.
Quote bash script for mandelbrot generation:
#!/bin/bash -i # Draws a mandelbrot set. # Author: Benjamin Staffin # # Simulates floating point by using big integers. Flagrantly uses two integers # instead of complex numbers. I couldn't be arsed to calculate infinity limits # of logarithmic functions in bash, so this just uses escape time values for # colors. # # Algorithm reference:

L=128 # Iteration limit. Even on a 238x61 terminal, 99 is plenty. P=100000000 Q=$(( P/100 )) X=$(( Q*320 / ($COLUMNS-1) )) Y=$(( Q*210 / $LINES )) y=$(( Q*-105 )) v=$(( Q*-220 )) x=$v
# "pixel" 0,0 is the top-left corner of our character grid.
# Outer loop: lines (y values) while (( y7 )); then (( k=1, j-= 8 )); else k=0; fi
# ANSI SGR color codes start at 30, hence j+30 here: printf "\E[$k;$((j+30))m#"

xnews (this client) is a Windows application.
What makes you think, however, that I am running it from a windows session?
Well, even under Linux boot and wine, I guess it is "a Windows session". Hahaha...
The point is you can't tell. There is no linux version of xnews, so the only reason to run it under wine under linux would be liking it better than the linux news clients.
That proves it... I am currently under Windows. ;-) (moral: xnews sucks)
All our production testing is automated and pushes test data and a PDF test report into a database. We need to do that for many reasons. Nobody takes data on clipboards. Sometimes they might type in something, like a power supply current, but we try to automate stuff like that too.
But I'm not a test tech, I'm an engineer.

You don't get it. I STILL plot points BY hand on a graph on my clipboard at the bench, just like you do, Johnny Rotten.
Damn, you are illiterate, boy.
And by the way that decidedly means that you are as slow as f*ck. Your deliberately applied tunnel vision is probably an order of magnitude more stupid than any of the stupid shit our CIC has pulled... so far. You are both running neck and neck though.
Qubes OS is a Xen distribution that handles Linux, Windows, and other systems. The VMs have tightly controlled access to each other (nearly none by default).
I used to use a Win7 VM until I figured out how to run all the apps I care about in Wine.
