FlyMoreRockets··on AeroPython: Classical Aerodynamics with Python
This is really good, thanks for submitting it.
FlyMoreRockets··on Low Cost Metal 3D Printing by Electrochemistry
I can see an immediate appliation for this technology: printing combustion chambers for regeneratively cooled liquid rocket engines. Electrforming is state of the art for these engines already. Sure, it's slow, but production rates aren't typically very high.
FlyMoreRockets··on Basic Scripting with Awk and Gnuplot
I note with interest the article links to: https://ferd.ca/awk-in-20-minutes.html

Very succinct quickstart guide.

FlyMoreRockets··on Open-Source E-Paper Smartwatch Kit
I haven't worn a watch in over a decade. This project has me reconsidering.
FlyMoreRockets··on What classic game would you like to see remastered?
I'd like to see a remake of Major Havoc and a homage to the original arcade Battlezone. FWIW, Major Havoc recieved a "Director's Cut" a few years ago: https://mhedit.askey.org
FlyMoreRockets··on OpenMotor: An open-source internal ballistics simulator for rocket motors
Pretty sure BRL-CAD is only for solid modeling. This is the first I've heard that BRL-CAD can sim propellant combustion. Can you provide a pointer to documentation? I tried a few searches and couldn't find anything relevant.

I've been meaning to learn BRL-CAD, but haven't had a strong motivator. This would be sufficient.

So you are saying Trump or Addleson or the Koch brothers should invest in the service.

If we use the wisdom history provides, we don't need to have the war.
FlyMoreRockets··on A guide to running IRIX 6.5.22 in MAME
I expect you could. Then you could install Win3.1 running on DosBox. Or even a recursive MAME install...
FlyMoreRockets··on How Do You Solve a Problem Like QAnon
Thoughtful and interesting analysis. I wonder if the author has considered his that proposal is a double edged sword.
FlyMoreRockets··on Yarchive
Usenet Archives collected by Norman Yarvin

In which the host has filtered the signal from the noise until the S:N approaches unity.

Wide range of practical information.

FlyMoreRockets··on Some Files
There are some real gems here. Love the plain text format.

Reminds me of the Yarchive. https://www.yarchive.net

FlyMoreRockets··on Akin's Laws of Spacecraft Design
Valid point. Also, if one wants to stretch the envelope, Harold Graham, flying the Bell Rocket Belt, performed the first rocket powered landing, April 20th, 1961 at Bell Aerospace, upstate New York. This development footage opens with that flight: https://www.youtube.com/watch?v=gxmxbMdToR4

My math shows the technology to be 22 years old.

Not mentioned in the above link was an amateur group developing VTVL tech around the San Francisco bay area in the 90's. IIRC, it was EPRS. FWIW, they also invented a multi-rotor platform to test their conrol system that evolved into the modern drone.

FlyMoreRockets··on LA: Ambulance crews to not transport patients with little chance of survival
The state where I live has opt-in organ donation option when you apply for a driver's license/state ID. As a retired EMT in a rural area, I encountered organ donation cases twice in my career. Once, the patient was flown out, the other time, the orgqan donation crew was flown in. The first case, the patient had suffered a gunshot wound to the head that spared the autonomic functions, he was breathing on his own.
FlyMoreRockets··on GNU Units
I do these kind of calculations all of the time and never realize units had this level of functionality. Wow, thanks Faaak!
