Over the years I have written many small applications and utilities.

In order of sophistication these include:

Simple HTML web pages
Command line scripted utilities and batch (BAT) files
Embedded Java code in web pages
Word and Excel macros typically written in Visual Basic for Applications VBA
Simple databases with VBA or Visual Basic (VB) VB frontends
Database related SQL queries batch data manipulators, templates and structures
Simple stand-alone utilities in in VB
Windows utilities written in plain C++ or using the Microsoft Foundation Classes (MFC)
Fully featured relational databases using SQL Server and VB
Complex applications written in C++

Some examples include:

Automatic footers and metadata updater code for Word and Excel; optionally to bring up a dialog to ensure file naming conforms to a standard.
A utility to process business financial data to reveal a variety of comparable ratios indicative of business health.
An applications to change registry settings and to install and run files on desktops and servers across a network.
A library (DLL) of simple encryption routines that add no overhead (don't change the file size) that can be used on any file; or encrypt in URL friendly characters to secure URL strings sent to web pages.
Several applications based around this library that can easily be called by applications written in languages other than C (VB, VBA, Java, C# etc).
File manipulation software for archiving, file moving and general file management; providing scripted batch processing archiving and reporting.

I'm happy to provide more information on any of these on applications or tools. Use the contact facility on this website.

Travel

Southern Africa

In April 2023 we took a package tour to South Africa with our friends Craig and Sonia. We flew via Singapore to Cape Town.

Cape Town is the country's legislative capital and location of the South African Parliament.
It's long been renowned for Table Mountain, that dominates the city.

Australia's Hydrogen Economy

As anyone who has followed my website knows, I'm not a fan of using 'Green Hydrogen' (created by the electrolysis of water - using electricity) to generate electricity.

I've nothing against hydrogen. It's the most abundant element in the universe. And I'm very fond of water (hydrogen oxide or more pedantically: dihydrogen monoxide). It's just that there is seldom a sensible justification for wasting most of one's electrical energy by converting it to hydrogen and then back to electricity again.

I've made the argument against the electrolysis (green) route several times since launching this website fifteen years ago; largely to deaf ears.

The exception made in the main article (linked below) is where a generator has a periodic large unusable surpluses in an environment unsuitable for batteries. In the past various solutions have been attempted like heat storage in molten salt. But where there is a plentiful fresh water supply, producing hydrogen for later electricity generation is another option. Also see: How does electricity work? - Approaches to Electricity Storage

Two of these conditions apply in South Australia that frequently has excess electricity (see the proportion of non-hydro renewables chart below). The State Government, with unspecified encouragement from the Prime Minister and the Commonwealth, has offered A$593m to a private consortium to build a 200MW, 100t hydrogen storage at Whyalla. Yet, the State already has some very large batteries, with which this facility is unlikely to be able to compete commercially. Time will tell.

Climate Emergency

emergency
/uh'merrjuhnsee, ee-/.
noun, plural emergencies.
1. an unforeseen occurrence; a sudden and urgent occasion for action.

Recent calls for action on climate change have taken to declaring that we are facing a 'Climate Emergency'.

This concerns me on a couple of levels.

The first seems obvious. There's nothing unforseen or sudden about our present predicament.

My second concern is that 'emergency' implies something short lived. It gives the impression that by 'fire fighting against carbon dioxide' or revolutionary action against governments, or commuters, activists can resolve the climate crisis and go back to 'normal' - whatever that is. Would it not be better to press for considered, incremental changes that might avoid the catastrophic collapse of civilisation and our collective 'human project' or at least give it a few more years sometime in the future?

Back in 1990, concluding my paper: Issues Arising from the Greenhouse Hypothesis I wrote:

We need to focus on the possible.

An appropriate response is to ensure that resource and transport efficiency is optimised and energy waste is reduced. Another is to explore less polluting energy sources. This needs to be explored more critically. Each so-called green power option should be carefully analysed for whole of life energy and greenhouse gas production, against the benchmark of present technology, before going beyond the demonstration or experimental stage.

Much more important are the cultural and technological changes needed to minimise World overpopulation. We desperately need to remove the socio-economic drivers to larger families, young motherhood and excessive personal consumption (from resource inefficiencies to long journeys to work).

Climate change may be inevitable. We should be working to climate “harden” the production of food, ensure that public infrastructure (roads, bridges, dams, hospitals, utilities and so) on are designed to accommodate change and that the places people live are not excessively vulnerable to drought, flood or storm. [I didn't mention fire]

Only by solving these problems will we have any hope of finding solutions to the other pressures human expansion is imposing on the planet. It is time to start looking for creative answers for NSW and Australia now.
