Better Cygwin Terminal

I just searched for a better cygwin terminal and found the following resources:
* Better Cygwin Terminal
* How can I copy and paste into Cygwin console windows?
* Setting up RXVT

My cygwin.bat currently looks like this:

@echo off
chdir C:\cygwin\bin
start rxvt -sr -sl 10000 -fg white -bg black -fn "Lucida Console-10" -tn cygwin -e /bin/bash --login -i

Update 2004-09-09:
I still was not really satisfied. The colsole behaved good, but I wanted to have the same comfort putty is giving me.

Fortunately I found the solution:
* PuttyCyg
It is a patched version of putty and adds 'cygwin' as alternative protocol to raw, rlogin, telnet and ssh and is just what I was looking for a long time!

Using it is really simple:
* Download, extract and start puttycyg.exe
* Select the 'cygwin' protocol and enter '-' as hostname

If you want to directly start a terminal window without GUI interaction (as I like it) use the following command:
puttycyg.exe -cygterm -

Apache Portable Runtime 1.0.0 Released

Apache Portable Runtime 1.0.0 Released: "The mission of the Apache Portable Runtime Project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behavior regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features." - Redirect After Get - Redirect After Get: "All interactive programs provide two basic functions: obtaining user input and displaying the results. Web applications implement this behavior using two HTTP methods: POST and GET respectively. This simple protocol gets broken when application returns web page in response to POST request. Peculiarities of POST method combined with idiosyncrasies of different browsers often lead to unpleasant user experience and may produce incorrect state of server application. This article shows how to design a well-behaved web application using redirection."

Problems of logging-wrappers

Ceki Gülcü wrote an excellent article (Think again before adopting the commons-logging API) about what's wrong about logging wrappers. It's not very new (November 2002 with updates in April 2003) but gives some very interesting points.
Although he's a bit biased towards log4j he gives some valid points though.

Creating custom 404 error pages

What should you take into account when you create custom 404 (Not Found) error pages?
That's the question I just asked myself and did some "Google Research".
I got lots of results how you have to configure Apache or IIS, but that's not what I'm interested in.

Here are some results which cover what I want to know:
* Useful "Page not found" error pages
* Implementing Sensible 404 Pages With Apache

Java-based Argument Parsers

I just was in the need of an java-based argument parser.

That's what I found:
* JSAP (pretty active; seems to be the most advanced incl. usage generation, support for datatypes and Unix-style cascaded configuration files with default values)
* jcmdline (not as active as JSAP; aims for standardized commandline options, allows more sophisticated validations, displays usage and error messages)
* JArgs (not much active, very simplistic and easy to use)

It's hard to say which one is the best, since all suite different needs.
If you wonder, for my task I chose JSAP, but I'll keep an eye on all of them.

Update 2004-04-23:
Phil Wilson pointed me to one more:
* Apache Jakarta Commons CLI (seems to be similar in functionality and usage like JSAP)
