With the extraordinary revelations coming out of England’s regarding ‘The News of the World’, personal privacy had suddenly hit the headlines; at least in the non-Murdock papers.  

But of more concern than having one’s telephone tapped, is the risk of having one’s computer tapped.  Private papers, photographs and other files as well as your bank accounts and other ecommerce connections are particularly vulnerable to anyone with direct or remote access to our computers and/or personal devices.           

How might we prevent a ‘private investigator’, ‘investigative journalist’, ‘hacker’ or other criminal getting access to our files and invading our privacy?    

And how secure is the Internet that most of us use everyday?

 

 

 

 

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.

Bridge over the River Kwai

 

 

In 1957-58 the film ‘The Bridge on the River Kwai‘ was ground breaking.  It was remarkable for being mainly shot on location (in Ceylon not Thailand) rather than in a studio and for involving the construction and demolition of a real, fully functioning rail bridge.   It's still regarded by many as one of the finest movies ever made. 

One of the things a tourist to Bangkok is encouraged to do is to take a day trip to the actual bridge.

Reminiscing about the 50’s

 

 

Elsewhere on this site, in the article Cars, Radios, TV and other Pastimes,   I've talked about aspects of my childhood in semi-rural Thornleigh on the outskirts of Sydney, Australia. I've mentioned various aspects of school and things we did as kids.

A great many things have changed.  I’ve already described how the population grew exponentially. Motor vehicles finally replaced the horse in everyday life.  We moved from imperial measurements and currency to decimal currency and metric measures.  The nation gained its self-confidence particularly in the arts and culture.  I’ve talked about the later war in Vietnam and Australia embracing of Asia in place of Europe.

Here are some more reminiscences about that world that has gone forever.

A modern fairytale - in a Parallel Universe

 

I've dusted off this little satirical parable that I wrote in response to the The Garnaut Climate Change Review (2008).  It's not entirely fair but then satire never is.

 


 

 

In a parallel universe, in 1920† Sidney, the place where Sydney is in ours, had need of a harbour crossing.

An engineer, Dr Roadfield, was engaged to look at the practicalities; including the geology and geography and required property resumptions, in the context of contemporary technical options. 

After considering the options he reported that most advanced countries solve the harbour crossing problem with a bridge.  He proposed that they make the decision to have a bridge; call for tenders for an engineering design; raise the finance; and build it.  We'll call it the 'Sidney Harbour Bridge' he said; then less modestly: 'and the new crossing will be called the Roadfield Highway'.
