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

as a comparison to - 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


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.

Journal files need to be samller than the default 4GB!!! So set it down to something nice like 100M

Change in /etc/systemd/journald.conf



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

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

AND export your 'installed' packages to have a list of things to rebuild later….

My scripts to cheat off:



OpenHAB huge range of supported equipment that can be interfaced




Apple changing architecture - so what will be the ramifications of 'architectures' around the world….. even the impact on RPi for instance…

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.

“across multiple OSes in a virtual machine for Mac”

 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:


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

Cross compiling Rust from Linux to macOS

AJ query:

text-to-Speech solutions anyone?

'Festival' from 2002!

(SayText “hello dave, you don't want to do that dave”)

install male or female Amercian voices…..

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 “$*&tl=en ”; } say $*`
