Specs for my first self-funded computer

This was on my UVI student web-server website.  Amazing how long I have come.

A useless machine….

Powershell – Max the bright

This script increases the brightness to max

set-ExecutionPolicy remotesigned -force
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,100)

I build for me….

I build tools for my use.  Hardware, Software, and services.  I build not to sell, rent and/or give to others.  One cannot solve the problems of others, until she can solve her own.

While I am supporter of Free Software, both beer and freedom, I most importantly support the freedom to do what you want.  This is because I don’t want anyone telling me what to do with my life.

If I follow your instructions, know that it is because I deem it in my own best interest.  Our goals have been aligned.  Nothing more, nothing less.

ZFS Testing

Spent the day testing ZFS, via FreeNAS, as a VM storage medium.  Got it to do snapshots, rollbacks, clones and the most important, incremental backup to remote systems.

The goal is for this to allow my core data to be replicated to remote repos for security issues.  This is most imperative after Irmaria.

Resources that were most helpful.

Automata

Automata theory is the study of abstract machines and automata, as well as the computational problems that can be solved using them. It is a theory in theoretical computer science and discrete mathematics (a subject of study in both mathematics and computer science). The word automata (the plural of automaton) comes from the Greek word αὐτόματα, which means “self-acting”.

Veranda to dish….

On June 20th, I took the step to self reliance and purchased an vertical aeroponics system from Al Henry [alhenry2@gmail.com] a local(USVI) hydroponics system maker and this weekend harvested the first of many produce.

Here is the system

Before

Currently:

Plants are :

Kale
Parsley
Thyme & Oregano
Basil
Spinach
Collard Greens
Lettuce
Arugula
Onions (Scallions)
Chives
Rosemary
Sweet Marjoram
Cilantro
Swiss Chard
Mustard (Greens)
Lemon Grass
Mint
Sage
Tarragon

 

This is a time lapse of the system(click on image to start animation):

And the resulting meal that used produce from the system.

Heart Beat shell script

I use this script to get alerts from some systems to insure they are still up.  It gives me local IP address, hostname and the WAN IP for the network.

 

#!/bin/sh
IP=”$(ip addr | grep ‘state UP’ -A2 | tail -n1 | awk ‘{print $2}’ | cut -f1 -d’/’)”
IP2=”$(curl ifconfig.co)”
HST=”$(hostname)”
CN=”$(curl ifconfig.co/country)”
CT=”$(curl ifconfig.co/city)”
HST=”$(hostname)”
echo $IP2 > /tmp/$HST
echo $IP >> /tmp/$HST
echo $CN >> /tmp/$HST
echo $CT >> /tmp/$HST

/usr/bin/sendemail -t info\@mydomain.org -f hb\@mydomain.org -u “HB from $HST” -s smtp.server -o message-file=/tmp/$HST;
