Organizations that write software for free spend even less
money and resources (is it possible!?) on technical writers
than reputable gouge-the-public software companies. So even
though there is an "official" release of new software, that
doesn't mean anyone can use it. Typically there are bugs,
the documentation appears to have been out-sourced to a
small African country, and sometimes you just run into
unexpected "features" that leave you utterly perplexed for
days. When you know no one is getting rich, you are more
tolerant. ("Harry probably knocked this out over his corned
beef sandwich the other day. Let's cut him some slack.")
I'm telling you this not to enlighten you to the real world,
but to point out why you are not likely to find the latest
up-to-date version of a library in commercial software. Not
enough hours in the day, mostly. And let'em fix their
own damn bugs. Why should I be doing it for them! :-)
Not to mention when paying customers find things don't
work they, uh, complain a bit more vociferously.
HDF5 is important to RSI. They will get the latest libraries
built into IDL as soon as they can. I wouldn't look for
"updates". Rather, I would wait (and pray) for the regular
releases to feature it. (Sometime this summer, is what I hear
for the next IDL release. I've no idea about HDF5 1.6.2.)
Cheers,
David
P.S. Let's just say if I were going to be cutting edge,
I'd be getting on the Mac bandwagon. But I have enough
problems as it is, so....
