Ruby before Ruby ???
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there. I was searching some stuff about Ruby and found this: http://www.cooper.com/alan/father_of_vb.html There was a Ruby before "our" Ruby, and it's known as Visual Basic today!= Jesus! Something that worried me was these words: "Because Microsoft owned exclusive rights to Ruby, they could do with it = as they pleased." Argh! Is the actual "Ruby" name ok, regarding the mark stuff? Some more links about that: http://www.forestmoon.com/BIRTHofVB/BIRTHofVB.html http://www.webword.com/interviews/cooper.ht...

the power of Ruby and #ruby-lang
Two days ago, I mentioned I'd like to be able to read .dbf files. Yesterday, I mentioned it again. One of the replies I got was essentially "it's easier than you think, just build it. here's a link to the specs. I've written an xBase interface before, and I'll help you if you get stuck." That said, I looked. 24 hrs later, I now have a tool that will open and read .dbf files - including memos. It can't write them yet, but I've spec'd that out, and have the basics done (and tested). When I started this, I knew nothing about the xBase file specs, ...

Tk Ruby / Fx Ruby / Wx Ruby
I have looked at these three GUI's for Ruby, and would like to know which the community feels is the better of these three (or is there a better one that I haven't listed). I am building small applications with UI's that are not too complicated, and wrapping the apps into exe files with rubyscript2exe. I like the smaller size of the final product when using Tk, but the native look of Fx and Wx. What has been your experience with GUI toolkits for Ruby?

What is better Java with Python or Java with Ruby ?
Hi every one I'm tying to use out script in java code. and I want to be OS Independent sometime function which is java can not provide it like e.x. ICMP So I was wondering if any one can help me with this what is better ?

Installing a second runtime package doesn't sound like something an end user would want to do. Plus ICMP is an often- and easily-abused protocol. I'd stay the heck away from it. Off the top of my head, I think both provide about the same level of OS independence. If you must choose, pick either and then just use it.

ruby language parser in ruby

Ruby Quiz for building up Ruby?
I put this suggestion to James Edward Gray II as a means to an end. I was thinking that if the quiz inspires people to tackle manageable problems, then it might be that we can use it to help us improve Ruby itself. We may get components for packages built up for the cases where people find them sufficiently interesting to write. So, would anyone object to this strategy? Is the problem expressed below sufficiently challenging to be of interest to those who know they could tackle it? Does it make a good quiz? James said I should ask, so I am. <quote> Date: Wed, 26 Oct 2005 18:11:1...

Maybe you will be able to use C or C++ as a common "glue code". There is also a program called SWIG, used to make Java, Ruby, Python, etc... work with C.

Ruby Vs. Java
Which programming language is faster - Ruby or Java? This is one of the things that will decide whether I use Ruby or Java so help is appreciated greatly. Thanks. -- Posted via http://www.ruby-forum.com/. Java code is definitely faster than Ruby code. However, to solve same problem, programming in Ruby should be faster than doing that in Java.

Development speed: Ruby, hands down Execution speed: Java, hands down That said, the main problem with execution speed are poor algorithms. With ruby, you develop it, maybe in a quarter of the time you'd need in java, then you see if it is fast enough. Most often you'll see it already is. If not, you profile. Most often you'll then notice it is one or two bottlenecks only. You'll see if you can make it faster using pure ruby, if that fails, you can always write a C extension (or use a java lib if you use jruby). In the end you spent half the time you'd spend with java and your app runs fas...
