comment A bug in Integrate
@Szabolcs: It would make sense if m.se had a separate section for bug reports. WRI definitely WILL notice them and deal with them, simply because they are on public display and they'll want that list to shrink. With their internal bug reporting mechanism, they pick and choose what they want to fix and what they want to leave as is. I've reported two bugs in 2004, that was 5.1 iirc, and they're still not fixed. Sometimes public display is the only way to get improvements.

comment Express recursion formula by Nest function
"I have to express a formula by Mathematicas Nest-function". Are you sure about that? It's possible with Nest, but not in an obvious way that's easy to understand for a newcomer. Oftentimes constraints like "have to use ..." are unknowingly self-imposed. And here's another tip: recurrence equations are the discrete analogues to differential equations, and to solve either of them numerically you always need some initial or terminal condition. n*f(n-1) is only factorial if you initialize f properly. If you set f(1)=17, you don't get the factorial. Good luck!

comment Is there a way to profile Mathematica code in batch mode?
Do you HAVE to run it through the WB? It's easy to run a M program in batch/command line mode. But you keep referring to the WB. As you have all the .m and .nb files on the local file system anyway, why don't you just run it in batch/command line mode from there? I don't see the dependence on the WB for what you are trying to accomplish. And the simply put some Print statements with time stamps or wrapping AbsoluteTime interspersed throughout the code (or include code that dumps time stamps into some log file), and then run several times to encircle the salient parts of the code.

comment Can Enterprise Edition really encrypt code for distribution via CDF?
@Kuba, sorry for the long wait, I was absent for a while. Yes, the key-based RSA encryption is indeed encryption. Parts of Encrypt seem to be bolted on to OpenSSL, although I can't tell yet to what extent OpenSSL is used. If it's coded correctly, it will probably be all right. A friend of mine informed me that the Windows version doesn't seem to encrypt RSA without the padding routine, contrary to the documentation, but as I'm not a Windows user, I couldn't check that. Tests with PowerMod show that the keys and exponents work correctly, so I'd call it encryption.
