Hi all,
IDL 8.4 and ENVI 5.2 have just been released! If you are current on maintenance, you can download the latest release at:
http://www.exelisvis.com/MyAccount/Downloads.aspx
Just be patient if it's slow, because there are a lot of people downloading...
What's new? Here is a brief summary:
--------------------
ALOG2 function
--------------------
BigInteger class: Allows you to create and manipulate integer numbers of any size. For example:
b = BigInteger(2)^1279 - 1
PRINT, '2^1279 - 1 is prime?', b.IsPrime() ? 'true' : 'false'
c = b.NextPrime()
PRINT, 'next prime is ', c - b, ' greater'
--------------------
BOOLEAN Variables: Boolean variables are actually variables of type BYTE with a special boolean flag. There are also two new system variables, !TRUE and !FALSE.
--------------------
Code Coverage: You can now analyze the code coverage for your applications using the CODE_COVERAGE function. The function returns the line numbers of code that were executed and not executed for your given routine. In addition, the Code Coverage feature has been integrated into the Workbench.
--------------------
Folder Watch: The new FOLDERWATCH object monitors folders for changes and invokes a user-defined callback whenever a change occurs.
--------------------
FFT Power Spectrum: computes the Fourier Power Spectrum of an array, with optional filtering.
--------------------
Generate Code in New Graphics: generates the code needed to reproduce the contents of a graphics window.
--------------------
Lambda Functions and Procedures: create simple inline routines that can be used for functional programming. For example:
IDL> compile_opt idl2
IDL> lam = LAMBDA(n:n le 3 || MIN(n mod [2:FIX(SQRT(n))]))
IDL> PRINT, lam(499), lam(4999), lam(49999), lam(499999), lam(4999999)
--------------------
Variable Attributes: You can now access special attributes on all IDL variables. For example:
var = RANDOMU(seed, 200, 100)
PRINT, var.length
PRINT, var.ndim
PRINT, var.dim
PRINT, var.typecode
PRINT, var.typename
--------------------
Static Methods for IDL Variables: You can now call special static methods on all IDL variables except objects and structures. For example:
var1 = RANDOMU(seed, 200, 100)
PRINT, var1.Mean()
PRINT, var1.Total()
var2 = var1.Sort()
HELP, var2
--------------------
Plus a bunch of other feature enhancements and library updates. See the "What's New" in the IDL documentation for the full list:
http://www.exelisvis.com/docs/WhatsNew.html
--------------------
As always, IDL is backwards compatible. All of your existing IDL code should continue to work as it did before. SAVE files created in earlier versions of IDL will work fine. In addition, SAVE files created in IDL 8.4 should work fine in IDL 8.3. Finally, we preserved the binary compatibility of IDL 8.4 with 8.3 - so libraries (such as the Slither Python module) should continue to work in 8.4 without needing to be recompiled.
Cheers,
Chris

I was reading the what's new (http://www.exelisvis.com/docs/WhatsNew.html). There are lots of wonderful new things!. Chris' post doesn't do justice. Some of the new features I have wanted for a very long time: filter, map and reduce for hashes and lists, list sort (with user-selectable comparison function), generatecode,lambda functions, variable attributes.
All of that is much appreciated, Chris.

Thanks for the kind words! Please post here when you do exciting and cool things with the new features. I'm always interested in hearing about how people are using IDL, what kinds of data are being analyzed, different types of visualizations, etc. That's what keeps me coming into work every day. :-)

You might have heard that the next cool and exciting possibility I am examining is how to deploy IDL in Amazon EC2 instances. I am starting by using only the IDL VM, to see how it works. But eventually there would be the need for the full IDL, which would require a license. The ideal model would be to have IDL offered on the AWS Marketplace, so that the image would come with IDL installed and working, with the license charged through the AMI price. This would enable the use of images created and destroyed at any time, without having to worry with arranging for licenses.

Ah, the Live Tools. They pre-date me. They were an attempt at interactive plots, similar to the Matlab figure window. I think they came out around IDL 5.1 or 5.2, and they were quickly made obsolete by the iTools in IDL 6.0. The code is very difficult to maintain, and is cluttering up our code repository.
I'm sure that other people in the newsgroup have more to say on the topic. :-)

Exelis VIS clearly has never understood the web, but you can add the
feed to Feedly. Search for the following URL on Feedly, i.e., actually
paste the following URL into the Feedly search box:
http://www.exelisvis.com/Company/PressRoom/Blogs/IDLDataPoin t/TabId/838/mid/2923/ctl/rss/Default.aspx
That should find it and you can add it from there. Obvious!

Thanks, Mike! It had 9 Feedly readers when I signed up this morning. :-)

Hi Mike
That's not entirely true. Mark Piper used to have this blog at an easy to remember url. However, this url was outside the ExlisVIS firewall/IT premises and my guess is that this fact led to the demise of its existence in that location. I wish there would be at least a button on the main page to get to this blog, which I have always found extremely helpful.

Just wondering where did you get with creating an IDL AMI

Hi Chris,
I just need to have an access to IDL 8.4. I got 8.5 and it crashes everytime I tried to run RT_Image
Thanks

Hi Eman,
I would contact support<at>exelisinc.com and give them details about your machine, operating system, and a reproduce program.
Cheers,
Chris
