Doctor, it hurts when I do this!
Heh. You assumed I knew your architecture. Silly assumption. ;-)
You'd given me only bare outlines. From what you said it could be
easy or hard to convert.
Now that you've described your existing process more thoroughly I know
it would be a time-consuming bear.
Or I should say, I trust you that that's true because still haven't
seen the internals I don't have the PHP.
But you seem reasonably trustworthy. ;-)

Well, how about the python icalendar module i referenced, an example
of which i hacked up for you already. If you give me a sql dump file,
I'll even add the parse-the-sql-dump bit I left out and see if it'll
As you can probably tell right now, I'm a lot more comfortable hacking
python than php, and I'm willing to help.
If you want me to.

Or just set up a cron job. Do you care that much if your changes
come out now or five minutes from now?

Sure, well, sometimes it's easier to change to a simpler way and
factor out the existing cruft. Since I don't know how clean or crufty
your php is (I see the rendered output, remember, not the mysql or the
I trust you to be the judge of that
And I'm certainly not asking you to take on a big rearchitecturing
job. But without access to your internals the best help I can be is
to pop in with hopefully-helpful bits here and there that may help you
do the bits you might eventually want to do.
That's what I've been trying to do anyway.
Sorry if it was confusing.

No that's cool.
It's your site, not mine, and I apologize if I gave the impression at
any point I was trying to boss you around.
If you want to drop the subject it here and now that's your prerogative.
But if you want to back burner it and feed me bits here and there to
do that I actually can do, that's cool too.

Well, if you give me database dumps and php code, maybe I can do just
that. Maybe not today or next week, but in the next couple of months.

You point is well taken.
Well, 90% well taken.
5% doubt: if icalendarphp version that takes *seconds* of CPU time to
serve up a small plaintext file will certainly cause noticeable load
if multiple people hit it simulatneously. And you have to admit that
the BALE is popular.
5% doubt: There is this feature of thttpd where you can tell it to
throttle certain kinds of files. That way it can still be responsive
even though the connection is saturated.
I.e. software actually can make a difference even where there's a huge
processing power to pipe differential.

Well, I said that was how I'd do it, several times, premised on the
assumption that you didn't seem to share that static sites work better
than dynamic ones and professing ignorance at the internals of your
Doctor, it hurts when I do this!
Well, stop doing it!
And I explained up front that I'd written a quick one-way hack on that
assumption that that didn't seem to confuse you until later.
But yes, it's good that you got over it once you understood that I
hadn't understood that you have a large and complex php and mysql
structure you'd rather not change...
I didn't think I was being unilateral but you kept sounding like you
didn't understand how the issues you had raised as major issues were
based on certain assumptions so I had to explain them further and
further until I finally understood what your assumptions were.
Anyhow, now that your assumptions and architecture have been a bit
better illuminated we can go back to whatever direction you wanted to
take the conversation discuss before I "unilaterally" derailed the
Go back, pick up the thread, pray continue, fine sir, to where you
were before I so rudely interrupted.
