V4.1  (2025-11-30)   

Last update 2025-11-30

 

Currently doing:

 

(Spin up testing framework - In progress.) AAGI / AASI experimentation on Raspberry Pi's (Pi 4/5) (Started 2023-07-11) - 107 Hours

 

 -Experiments on visual processing for tracking objects and trajectories of objects across all cameras and reporting this in a PDF. PDF Report engine currently being coded late 2025/ early 2026. (in progress)

 -Hardware/software setups for Asus NUC Pro 14 Ultra I7 with Ubuntu 24.04 (noble) (two units: highly available pair with one master the other slave) and PI4/5 units to be used as dev test beds and processing. (in progress)

 

 

(Personal - In progress.) Pen Testing using Kali O/S tools - 10 Hours

 

-Learning Kali O/S utilieis on a PI5 with 8Gb of RAM as a mobile pentesting device.

-Gain experience with pen testing my own local area network and all my physical computing hosts. 

 

 

Completed:

 

Hosting read-only owner-corporation documents (2024-06-16) - 3 Hours

 

 -Create OCxxxx subdirectory on main HTML publlishing tree. No index file.

 -Rename files for Unix filesystem and create link QR codes to these files hosted on this portal.

 

 

(Volunteered time - Completed.) Tsunami Uplift -   100 hours and 20 minutes to 27th April  2023.

 

-Dart event mode processing for new 4G Australian Dart sensor. (Codes refactored.) - Corrected behaviour of data preparation when individual dart event mode report had multiple readings across multiple transmissions for the same data time of a reported water column (1st Nov 2022). Working on system documentation and data flows for enhanced system support capability.

-Testing code against event data for 2023-02-20 on NZA DART. Ensuring regression unit-test for this type of DART completes successfully. Waiting on legacy DART event data to complete the CANNED data unit-testing. Javadocs and debug additions for dart data merge program. Javadoc and debug additions to dart buoy processing (normal data mode)

-Finished dart event mode unit test framework: coding, testing, setup, and documentation. Hand over all new codes, documenation, and unit test framework for installation. To finalise by client: Iridium type communications legacy dart event canned data capture.

 

 

(Proof of concept - Completed.) Setup Raspberry PI's (PI 3) for security surveilance with authenicated https webser to host last 6 minutes, 60 minutes and last 24 hours midnight to midnight video across 8 cameras.  (Completed 2023-03-08. In progress with software upgrade 2025-08-10 ongoing)

 

 -Setup and configure apache2 with https and global authentication login requirements for access to site.

 -Upgrade all the PI 3 units to latest PI O/S 32 Bit. Upgrade all PI4 and PI5 units to 64 Bit latest PI O/S

 -Upgrade software stacks and applications for continous HI_RES or LOW-RES video capture..
