Aeronetworks sro - Airborne Linux

Macs never die, sometimes you just wish they would, so you have an excuse to buy a new one.  This Macbook is a 2012 model with Retina display .  So it works very well indeed, but after 14 years, is not supported by Apple anymore. I put a new battery in it, available from iFixit and now it will once again run all day on battery.   There is a no nonsense Linux distribution, known as PCLOS, a distribution for Boomers and I guess I qualify!   https://www.pclinuxos.com/ PCLOS has no systemd and no SELinux or AppArmor, so it runs very fast and is excellent for antique machines.    However, for best results, there are a few things to configure manually on an elderly Macbook Pro. 1. Enable scrolling on the touchpad: # xinput ⎡ Virtual core pointer                          id=2    [master pointer  (3)] ⎜   ↳ Virtual core XTEST pointer        ...

I have a couple of old Macbook Pros, from 2012 and 2015.  They work better than when I bought them, thanks to new batteries from Ifixit .  However, there are some OS issues - processes that do not work well on older two core processors.  The photoanalysisd daemon is one of the useless things that saps all available processing power and killing it doesn't work - something always starts it up again. My simple solution is to delete a bad daemon.  If it isn't there, then it cannot run.    However a recent security update, restored it.  So after more than a decade of bliss, I had to delete it again, which is a little bit of an annoyance, due to the system integrity protection.  You cannot simply sudo and rm it.  You got to reboot a couple times.

I like the idea of a RC delta wing plane with a screaming jet engine and an EDF certainly delivers on the noise requirement , but what is not clear at all, is how much thrust an EDF can actually deliver.  So, today, I made an engine static test stand, that can sit on top of a small electronic scale.  An EDF engine mounted in the open doesn't look very nice on a plane, so I also tried a Starbucks Coffee Cup Conversion , to see what effect that has on performance. To cut a long story short: The only way that I could increase thrust, was with a better battery. For this 12 bladed 70 mm EDF, the manufacturer claims a maximum thrust of 2400 g.  However, with a 6S 1500 mAh battery, the maximum measured thrust was 1100 g and with a 3700 mAh battery, it was 1300 g. Any kind of coffee cup added to the engine exhaust, reduced the static thrust by 10 to 15%.  I slit the cup and tried an opening size from 68 to 55 mm with masking tape to hold it all together and keep the cup from...
