The are quasi autonomous.

The data gathering parts stuff semi real time data in a database,. which 
if it fails simply uses the previous value and copies it into 'latest'

i.e. it's of the form.

get last from database
If new data, overwrite it, else leave it
put it back in new database entry.

That was written first to get the data into the database way before 
other code was written to summarise it and graph it

I kept it separate because I did not want to risk the data gathering 
operation whilst I wrote the analysis and presentation stuff. Bugs in 
that, that cause crashes, do not corrupt the data.

It was a context specific decision. The sort of thing Jerry simply 
doesn't understand. Its not 'The Right Way' but in this case I felt it 
was the optimal way.

Mutatis mutandis, the code could have been written in PHP or C. I chose 
C because I am more familar with its way of handling errors. And it has 
slightly better tools to deal with things like timeouts on sockets and 
so on.

In short the two languages are pretty equivalent : PHP has better screen 
output tools and HTML specific tools - the ability to spit out raw HTML 
without 'printf' -ing it is the one reason I use it.

But I hate its sloppy typing. Its a hacker's language.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to 
lead are elected by the least capable of producing, and where the 
members of society least likely to sustain themselves or succeed, are 
rewarded with goods and services paid for by the confiscated wealth of a 
diminishing number of producers.
