Joe, Any language or tool not having an interface to RPG and native iSeries resources wouldn't meet your standards for enterprise-level business applications, if I understand correctly. Even Java alone, wouldn't meet your standards, which sounds reasonable to me. But Java gained traction across the world on the premise of "write once, run anywhere". That premise alone seems to have had incalculable influence on people, leading to expenditures in the hundreds of millions, if not billions of dollars, on Java based solutions, even though odds were that most Java projects would settle on supporting just one platform, usually the lowest common denominator - Wintel, but that could change to Lintel. The Rails community has come up with a few slogans of their own, like "convention over configuration". What it really means is that development under Java and .Net is too complex, and that the tooling required to support that level of complexity is unnecessary, given simplified programming interfaces. If Rails can offer that, it's something that will resonate with a lot of developers, particularly in this community. There are a lot of RPG programmers who assign field names and attributes in display file records the same as physical file records, so that mapping is done automatically between the two. That's an example of "convention over configuration". This discussion motivated me to look into the Rails philosophy, community, and architecture. It has been interesting. I've been reading accounts of Java and PHP developers creating Rails versions of their applications, and reducing the lines of code, cutting the code in half in one account, and comparing the versions for performance and scalability. The reports are favoring Ruby and Rails.

From: Jerome Hughes Both replies are completely unreasonable, show no sign of comprehension of anything stated, no questions answered, no valid points replacing the earlier trash, no actual ideas or knowledge expressed. DRY. Basically just doing your level best to attempt to ruin my night by casting me as the anti-you, which I most emphatically am not. Please find someone else to exercise this need against, or keep the need to yourself.
Jerome, I am not the first person to cast doubts about RoR, nor will I be the last. Whether I'm right or wrong in my opinions, your consistent approach of attacking the messenger rather than the message is not going to do anything to strengthen your position. Address my points. Show me where RoR has been used to write enterprise-level business logic. Show me how it interfaces to other languages, such as RPG. Then I'll be interested in it for the SMB business space that the midrange serves. I could be wrong about the language. My initial impression of EGL was pretty ambivalent as well, until I saw that it actually added something to the mix that I hadn't seen before: a WYSIWYG JSF editor that used program-defined metadata. When it added a clean interface to Java (and thus to RPG), that made me think it could be used for SMB solutions. Tools like Zope and RoR may be great, but if all they provide is the ability to build yet another web-based, light database solution, then they're less relevant to my clients. Again, I may be wrong, but nothing in my admittedly limited experience tells me it's any better for those things than Python is. Anyway, remember that I'm actually one of the milder dissenters you will have. I've programmed in Python and I understand the Ruby syntax. I may not have programmed Rails, but I've done a lot of research. You will get people who push back on it just because it's new, and if this is your idea of convincing such people, then I daresay you're probably going to fail pretty miserably. Okee dokee, enough. You're the one who started with "(wrote this last night, but held off sending it... also not looking for a debate, but perhaps can present another view, my friend...)". Please show the list more about the language as you learn more. I'm most interested in interfacing with legacy databases and being able to call host programs, but I'm sure there are others who will be interested in other capabilities. Joe
