Business application building with Ruby   11 Oct 04

Kirk posted this to the ML.
 I do this regularly, though most of the work so far has tended to be much
 more centric on web based applications.

 >> 1. A database
 >>     Java world: Oracle, MySQL or another relational DB of your choice


 >> 2. Some way to persist domain objects and manage transactions
 >>     Java world: entity EJBs, JDO, hand-coded DAOs, O/R <censored>
 >> mappers, etc

 Kansas has been maturing wonderfully for my purposes for this.

 >> 3. An RPC (remote procedure call) mechanism for communication between
 >> the front-end and the back-end (assuming that the front-end is a
 >> thick GUI).         Java world: session EJBs, servlets

 drb.  Works great.

 >> 4. A thick GUI
 >>     Java world: Swing

 TK, Qt, Fox

 >> 5. A Web GUI
 >>     Java world: JSP, XSLT, XMLC and all the other stuff

 I've use Iowa very successfully for this every day for a couple of years.

 >> 6. An asynchronous communications infrastructure
 >>     Java world: message-driven EJBs

 I am using Drb/Rinda/Tupleserver pretty effectively for this.  No problems
 with it at all so far.

Hi guys,

I backed to Japan with no trouble :)

I uploaded following resource used by RubyConf2004 presentation.

Very thanks to RubyConf staffs and attendances.

RubyConf 2004 sessions available (audio/mp3)   08 Oct 04
[print link all ]

We have made the .mp3 files (64kbs…downsampled from 192kbs) available of the sessions of the 2004 Ruby Conference. I added mp3 tags on all the files so they appear as an album (compilation) and the artist is the speaker. They are available from the RubyForge BitTorrent site. They are all in a single .zip file (…364MB)…there are a total of 20 mp3 files in the .zip:

Friday: 01-Welcome.mp3 02-RubyTraining.mp3 03-TestingWithRuby.mp3 04-Ruwiki.mp3 05-TychoPIM.mp3 06-HackingRuby.mp3 07-Alph.mp3

Saturday: 08-Narf.mp3 10-RubyOnRails.mp3 11-RailsDemo.mp3 12-RubyGems.mp3 13-YARV.mp3 14-TestUnit.mp3 15-Keynote.mp3

Sunday: 16-RubyOnWindows.mp3 17-Copland.mp3 18-CodeGeneration.mp3 19-Rubyx4DC.mp3 20-Closing.mp3


The torrent is:

If someone wants to get these, unzip and host them via HTTP that’s cool…we just don’t have the bandwidth :-) If someone wants them in 192kbs format, let me know via a direct email and we can work out how to get them to ya (its 1.4GB that way though).

                    Best, Rich

Retroforth 7.4   07 Oct 04
[print link all ]
RetroForth is a compact, open source Forth development system. It can be used under FreeBSD, Linux, BeOS, Windows, SCO OpenServer, or as an operating system. It is easy very easy to learn, use, and extend with standard libraries like SDL, and it can also be used to create tight, stand-alone applications.

Changes: This release adds quite a bit of new functionality. Support for aliases, filling memory ranges, and finding addresses of functions has been added. The native version has a serial console, serial port support, parallel port support, hard drive support, and interrupts. There are also two new ports using libc, one of which has support for using shared libraries. A few minor bugs in the conditionals were fixed.

R 2.0 is out   07 Oct 04
[print link all ]
R is a language and environment for statistical computing and graphics. It is similar to S, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc.). R is designed as a true computer language with control-flow constructions for iteration and alternation, and it allows users to add additional functionality by defining new functions. For computationally intensive tasks, Fortran and C code can be linked and called at run time.

Changes: Many things have changed since 1.0. The R language has acquired namespaces, exception handling constructs, formal methods and classes, much improved garbage collection, generalized I/O via connection objects, and considerable improvements in the graphics area. The user workspace has been reorganized, and so has the set of packages that ship with R. Several "recommended packages" deemed indispensable in a statistical system are bundled. In addition, there has been a large number of more specific new functions, tweaks, and bugfixes.

Erlang R10B   07 Oct 04
[print link all ]

Erlang is a small concurrent functional programming language developed by Ericsson. It is being used by Ericsson as a systems programming language for large concurrent fault-tolerant distributed systems.

Changes: This release includes two new applications, XMerl and EDOC. It increases the maximum number of simultaneous processes to 268 435 456. It adds several nice additions to the language, such as "Query List Comprehensions". It provides performance increases and several changes to included applications.
