JBooks 0.1.1 Beta

JBooks is a Java-based personal finance application. The main interface is a checkbook-like view, which allows you to enter and see your transactions. It is based around an SQL relational database, using a double-entry system for all transactions. That means that every transaction involves a transfer from one account to another.

The current version of JBooks is version 0.1.1 Beta. Future version will include additional features like reports, printing and Import/Export of transaction data.

WWW Usage 1.2.0 Beta

WWW Usage is a Java applet/application that analyzes web server access logs and converts them into nice, interactive graphs. It understands NCSA Common Log File format (CLF) and the extended Combined CLF.

The current stable version of WWW Usage is version 1.1.1. Version 1.2.0 is in beta state. The documentation here applies to version 1.2.0 final. Many things are different in the 1.1.1 and beta releases.

How to interpret the statistics

Availability

See WWW Usage in action - www_usage/
WWW Usage 1.1.1 public release - www_usage-1.1.1.zip
WWW Usage 1.2.0 beta release - www_usage-1.2.0.beta-4.zip

How to use this for your own pages

Unzip the www_usage.zip archive into some directory where your web server can get to it. It will create a file called www_usage.html and a directory www_usage.

Make a link from your usage log file to www_usage/www_transfers

Example1:

    cd www_usage
    ln ~/public_html/www_transfers www_transfers

Example2:

    cd www_usage
    ln -s /etc/httpd/log/access.log www_transfers

Load up www_usage.html in your favorite Java-enabled browser

Parameter Values

The list of possible parameter values is available in a seperate table. This includes the name, type, default and description of each parameter.

Changes Since 1.1.1

1.2.0

The number of changes from version 1.1.1 to 1.1.2 required an increase in the version release number. major version.minor version.revision

re-designed interface to use layout managers for better portability
implemented seperate filter lists for files and sites
added an icon image

1.1.2

Final version never released.

www_transfers file is now loaded in a thread, so WWW Usage can show the file is being loaded and possibly allow it to be stop/changed interactovely
added parameters fileFilters, siteFilters, display, hideControlPanel, hideStatusField, collapseItems. See Documentation
added logFormat parameter: handles either Common or Combined Log File format
added boolean parameters showAccesses, showDomains, showSites, showRFC931, showAuthUser, showItems, showUserAgents, showKBytes, showReferers, showCodes which control whether graphs are shown for these fields
added kBytes, ResponseCodes, RFC931, AuthUser and Referers graphing
click on an item in a pie chart legend to get a listing of all log entries for this item
filter settings can be set with the <param> tags filterFiles, filterSites, filters
sortLog parameter added: if true, the access log file will be sorted upon loading. This should only be used if you know the log file is not already in chronological order. A normal, un-modified log file should not need to be sorted.
changed layout of buttons and panels
applet & application are resizable You can change the WIDTH and HEIGHT tags in APPLET to whatever suits your needs
bug fix: Unknown clients/user agents being listed was a bug. All clients/user agents should either have a value, or be blank.

ToDo

See the Parameter Values table for parameters that have been added, but not yet implemented in the beta release.
Tell me what you think I should do.

Java Checkers

Java Checkers is a simple version of checkers that I ported from a Perl script I wrote for an AI class once. It's one player versus the computer. It's pretty fun to waste time with this.

Java Checkers is available here at http://www.pobox.com/~bereza/checkers/.

Docgen v0.3.2

Docgen is a program to automatically create documentation of Objective C class source code.

You can create documentation in multiple formats including RTF, HTML and plain text.

You can run docgen with a starting directory, and docgen will then look for any matching .h and .m class files. From those files it will create NeXT-style documents.

NEW The '-R' recursive option is seven times faster.

README

Availability

Docgen is available at ftp://ftp.csis.gvsu.edu/pub/docgen/.

Requirements

To produce .rtf documentation, docgen requires just a standard C compiler. To do .txt and .html you need Objective C with either the NeXT or GNU runtime. To dynamically load formatting classes requires the NeXT runtime.

Changes Since 0.3.0

0.3.2

the '-R' recursive option is now 700% faster
changed the behavior of the '-e' option. Text given in the '-e' is added to the class implementation file name
expanded '-C' switch to parse comments on lines with "/*" and on lines with "*/"
assorted big-fixes/suggestions/code-handling (Alex Blakemore, Pieter Schoenmakers, Michal Brouwer, Ralf E. Stranzenbach, Georg Tuparev)

0.3.1

expanded '-R' switch to have docgen search below the '-d' directory for .h files that match with .m files (the way -R worked before was not a bug but a feature)
added '-a' and '-b' switch to have docgen parse comments before and/or after method names

0.3.0

added multiple output formats with capability to easily add more (.rtf, .txt, .html) currently
added '-f' option to choosed formats (RTF TXT HTML)
added '-R' option to load new format classes
added real autoconf scripts and tested it on Linux, NextStep and AmigaDOS
Objective-C is required for multiple formats, but RTF still works for standard C.
on Nexts docgen can dynamically load new format classes
