APEX 3.1.5

Welcome to the APEX, Alan's Programming Environment Extensions.
"For more than a thousand generations the APEX was the guardian of peace and justice in the galaxy. Before the dark times. Before the Empire."

What is the APEX?

The APEX contains installers for lots of useful programs, all of which are freely downloadable from the Internet. It is a companion to the APE CD, which, in contrast, contains programs that can be run directly from the CD. You can download the latest versions of the APE and the APEX from Alan's Home Server.

Version 2.6.1

• The APEX has changed homes! The APEX is now being burned on a new computer running Windows 2000. The images used to build the APEX were moved in whole using the APEX ZIP archives. This initially appears to reduce some of the instability I'd been having, possibly at the expense of testing on multiple platforms (I do all my testing on Windows 2000 now.)

• Updated WinRAR archiving/compression utility to 2.80.
• WinZip installer upgraded to 8.1.
• Added WinZip command-line extensions.
• Java JDK install updated to 1.3.1_02. This version is horribly bigger than 1.3.1 for no apparent reason.
• Updated a lot of Cygwin utilities. I installed these once onto the APE and then backed them out because everything broke horribly. I guess when I wrote "somebody shoot me if I ever update Cygnus stuff for no good reason again," I was being too conservative. I need to make sure to never touch Cygwin again. Cygwin has got to go.
• Mozilla upgraded to 0.9.7 installer.
• PrintFile upgraded to version 2.1.5.
• Netscape 6.2.1 installer. Let me count the ways I love my new Earthlink DSL line, and how awful Qwest's service was. I'm getting over 1311 kBits/sec in file transfers.

• Cleaned up stylesheets.

Version 2.5.7

Version 2.5.6

• Added "Ape Airy" stylesheet for a different look, if you're using a browser that allows you to choose between multiple stylesheets.
• Made "APE Airy" the default stylesheet. You'll probably want to use an alternate stylesheet if printing (the "Compact" stylesheet works well for this.) You can always select the "APE Classic" stylesheet if you want a bit of nostalgia (or a display with less wasted space.)
• Mozilla upgraded to 0.9.5 installer.
• Netscape 6.2 installer (this is like Mozilla 0.9.4.1)
• Added Jakarta-Tomcat 4.0.1 installation image. This is a Java Servlet/Java Server Pages engine.

• Updated XEmacs to 21.4.5.

Version 2.5.5

• JDE (Java Development Environment) for Emacs/XEmacs install upgraded to 2.2.8. This does not require upgrade of the other associated tools for a change.

• Mozilla upgraded to 0.9.4 installer.
• Netscape 6.1 installer (this is like Mozilla 0.9.2.1.)

Version 2.5.4

• Moved a bunch of Java libraries into \javalibs
• Added gnupg (the GNU Privacy Guard) installation in \gnupg, a free encryption system that meets OpenPGP standards. Some work will have to be done on this to keep it from needing values in the system registry before it can be moved to the APE.
• Installed an early-release version of Sun's Generic Java (JSR-014) compiler and libraries. This is an attempt to bring a modicum of type-safety and code reuse to the Java language. I pray for the day that this facility makes it into the Java language (maybe 1.5?) In javalibs\Generic Java
• Installed an early-release version of Java JDK 1.4.0 beta install and documentation. Carting around five different Java installations is really starting to wear on me. Gravity always wins. It wears me out.
• Java CUP parser generator installation in \javalibs\javaCUP . This is a yacc-like parser for LALR(1) grammars in Java.
• JFlex, a Java lexer generator in \javalibs\JFlex . This is compatible with javaCUP.
