For nearly 25 years, I have been trying to "fix" IDL, either by writing programs that work the way I think they should work, or by teaching people how to work around IDL's shortcomings. I've grown old and cynical. I really didn't expect to feel much different after this week's User Group meeting. But I have to say that what I have seen in the past two days is not only good news for the casual IDL user, but is *great* news for IDL developers. I don't want to set expectations too high. This is just the first release in a new direction, after all, and I haven't really had a chance to play with the code and understand how it all works together. There are obvious pieces still missing. But this step is just absolutely in the right direction. For me, it provides tools that I can see myself using every single day. That hasn't happened for a LONG time. I said yesterday that one reason I haven't yet written that 3rd Edition of my book is that it is difficult to write while popping Prozac for depression. If you don't see a future for the software, why write about it? But this changes everything. I can see myself writing with Happy Thoughts once again. That, in itself, is enormously comforting. :-) Cheers, David P.S. The other thing cheering me up today is the fact that I will no longer have to support half the programs in the Coyote Library! Maybe I can give Coyote the boot and hire that young thing with the doe eyes to handle the lighter load. :-) -- David Fanning, Ph.D. Fanning Software Consulting, Inc.

("Perhaps thos speakest truth.") Lets us not forget all those great presentation on day two - all very good and inspirational. I’m glade to be an IDL programmer. Especially, David's talk about Map Projections. Maybe in their new Agile programming environment, ITTVIS will give us new up to date (PROJ4) mapping routines by IDL 8.1 release or as a patch.

Apparently Coyote has an iron-clad contract through at least 2025. Oh, well, we can't have everything, I guess. :-( Cheers, David -- David Fanning, Ph.D. Fanning Software Consulting, Inc.

No news, but repeated requests from the audience, especially during Tuesday's open forum. I think ITTVIS acknowledges the need, but--as always-- has a lot on their plate. In my view, they can't be doing graphics this nice without seeing clearly that this in how widgets should work, too. Personally, I think they understand the need. When they might get it done is anyone's guess. I didn't hear anyone give anything away, even in private conversations. Cheers, David -- David Fanning, Ph.D. Fanning Software Consulting, Inc.

Nothing wrong with doe eyes - if they're fresh! Good news, thanks for keeping us posted! Regards, Chris
I hope, that they will also give the opportunity to create real executable binaries are intend to do this in future releases. Make_rt is not a real option. Cheers CR

Make_rt > is not a real option. I would find that very surprising. IDL programs run on virtual machines, so it would be a major fundamental change to make it a native compiler. It is the same in other VM languages, as far as I know, such as Python and Java, for instance. Even though Java uses strong static types (much easier to compile), and has the JIT compiler (to make some parts into native binaries), no Java program runs without the VM. make_rt produces a more complete solution than can be done in Java, since it includes the VM, so it can be used directly (though there are the IDL VM limitations, which exist because IDL is not free). The way to distribute ready programs in Java, jar files, is more similar to making IDL save files. Since everybody has the Java VM, distributing jar files is more practical than distributing IDL save files. But IDL will never be as ubiquitous as Java, since it is neither free or a general purpose language.
