 +Mick
 +
 +Mick had a crashed HDD:
 +backup/recovery using TIMESHIFT    rsync and supports btrfs
 +after checking SMART system logs 
 +logs had shown it had used all available error sectors.....     disk had no reserve 20% space that SSD's need.
 +
 +new LTSP  Unix server project.   
 +
 +remote access  -  reverse VNC  session.....   
 +
 +type this on the technical computer end....
 +9:16
 +
 +Mick
 +vncviewer -listen
 +
 +port forward 5500 to your notebook through the home  firewall
 +
 +On the CLIENT's machine type this:
 +
 +sudo apt-get --yes install x11vnc;   x11vnc -connect  sudo  mlug-au.org
 +
 +
 +=================================================================================
 +
 +as a comparison to dwservice.net       -        reverse-vnc   is POINT-to-POINT.....   and could be wraped in an SSL encryption.
 +
 +=================================================================================
 +
 +systemD   auto-mounts   for a variety of on-the-fly access situation.
 +
 +==================================================================================
 +
 +NetFLIX  would benefit from  blackVPN
 +but downloading Lathe manuals is no big deal   .....   the data is encrypted so who would know.....
 +
 +==================================================================================
 +
 +Rpi and brewing beer
 +
 +-  Indian Pale Ales  are the go.
 +   PS:  after 10 years of fermentation, there is NO YEAST in Glenfiddich
 +
 +===================================================================================
 +
 +Danny/Michael
 +
 +Unhappiness of using  DOCKER
 +
 +but Mick has a trick of using a thin Debian 8 set of libraries with DOCKER to get a primitive set of old DOCKER tools up and running.
 +useful for running a LEGACY system
 +
 +use this set of scripts to assist.

 +Mick's weekend weather station project
 +
 +Hooking up sensors equally fun: DHT22 (temp/humidity), Light Sensors, Rain Sensors, WIFI (ESP8266), RTC, Magnet sensor, & BME680 for gas & such.

 +Bob  -  experience in having to rebuild his whole system after a disaster.....

 +ANSIBLE scripts are the go,  for rebuilding all your favourite tools again....

 +Apple changing architecture  -  so what will be the ramifications of 'architectures'  around the world..... even the impact on RPi for instance...
 +
 +https://www.apple.com/newsroom/2020/06/apple-announces-mac-transition-to-apple-silicon/
 +
 +Cupertino, California — In a historic day for the Mac, Apple today announced it will transition the Mac to its world-class custom silicon to deliver industry-leading performance and
 +powerful new technologies. 
 +
 +https://www.parallels.com/au/products/desktop/http
 +
 +"across multiple OSes in a virtual machine for Mac"
 +
 +https://www.darlinghq.org/
 +   Darling goes MAC to LINUX.......
 +   but is there a way of doing the reverse???                 LINUX to  MAC   scenario......   Danny  compiles everything JAVASCRIPT first and transfers....
 +
 +Danny is compiling gcc code under LINUX ....   into binaries to run under WINE  (compile the assets under WINE)
 +
 +====================================================================================
 +
 +WINE  runs a Windows app on Linux
 +darlinghq  runs a OSx app   on Linux
 +
 +but what allows you to prepare an app ON a Linux, that is targeted for OS-x  ?
 +
 +Mick suggests:
 +https://github.com/tpoechtrager/osxcross
 +
 +WHAT IS THE GOAL OF OSXCROSS?
 +
 +The goal of OSXCross is to provide a well working OS X cross toolchain for
 +Linux, FreeBSD, OpenBSD and Android (Termux).
 +
 +but will  OSXCROSS support the
 +transition the Mac to its world-class custom silicon

 +
 +Danny's  utilisation of GOOGLE TRANSLATE  and then output as SPEECH  is another solution.
 +The simple solution:
 +
 +`#!/bin/bash
 +say() { local IFS=+;/usr/bin/mplayer -ao alsa -really-quiet -noconsolecontrols "
 +http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&q=$*&tl=en
