Double.parseDouble()method in the new JDK 1.2 beta 4 although those methods are mentioned in the changes file.
Sun cofounder and Java advocate Bill Joy, currently working on JINI, has joined Novell's board of directors.
According to International Data Corporation, in the past year Sun passed IBM and HP to become the number one vendor of Unix servers.
amazon.com has XML: Extensible Markup Language back in stock. Current rank is 18,429. My associates report for last week only shows 12 direct sales. There are probably some sales that didn't go through my links. Regardless, it doesn't seem like it takes that many sales to move a book in their listings. Computer Literacy now has it ready for shipment in 2-3 days, and is offering international buyers free until the end of July.
IBM's alphaworks MediaBeans is a Java component framework for multimedia applications.
As you might expect, going out of stock doesn't seem to help a book's sales. XML: Extensible Markup Language dropped below 25,000 on the amazon.com bestseller list over the last couple of days though it's since bounced back to 3,920. This is depressing. I think I'm going to stop tracking this until they get back in stock. Computer Literacy has it in stock at their Vienna, VA store and can ship it from their web site in 7-10 days, and is offering international buyers free until the end of July.
XML: Extensible Markup Language reached as high as 390 on the amazon.com bestseller list yesterday and for at least two hours was the number one best-selling XML book before amazon ran out of stock. :-( Despite that little set back, it's continued to climb to 361. Although amazon currently lists the book as not yet published, that is incorrect. Amazon should have more copies soon, and it should also be available at other bookstores, online and off, very shortly. Computer Literacy has it in stock at their Vienna, VA store and can ship it from their web site in 7-10 days.
IBM's released the first public beta of Visual Age for Java 2.0. This release runs on NT 4.0 or 95 and supports Java 1.1.6 and Swing 1.0.2. IBM still hasn't done anything about the ridiculous RAM requirements of version 1. 48 megabytes of RAM is a minimum and 64 or more is recommended. Version 2.0 rolls in the alphaworks high performance compiler for Java. It also adds a remote debugger, data access beans, and team programming version control and source management tools. VisualAge for Java 2.0 will eventually be available on Windows NT, OS/2, OS/400 and AIX though for now it's only on Windows.
XML: Extensible Markup Language reached as high as 1,790 on the amazon.com bestseller list yesterday after debuting at 289,821, probably due to sales from this site and Cafe con Leche. This made it amazon's second best-selling XML book behind Simon St. Laurent's XML: A Primer at 138. XML: Extensible Markup Language was #9 of all XML books at Barnes and Noble, but they didn't have it in stock yet. As I write this XML: Extensible Markup Language is down to 2,355. (Update: as of 10:50 it's jumped back up to 1,163. XML: A Primer is at 219.)
I've been tracking it pretty closely to try to figure out exactly how many sales it takes to move a book where in the rankings. As Dan Gray, a fellow computer book author told me, "this amazon sales ranking is more addicting than the stock market" So far I'm tracking it manually, but this weekend I'm going to use a little Java Network Programming to automate the process so I can track these figures minute by minute. Maybe I'll even write a "book ticker" applet for web sites.
Netscape's released version 3.0 of their Directory Server Software Development Kit for Java. This SDK allows your programs to talk to LDAP v2 and v3 directory servers.
Sun's released version 1.0 of the payware development tool, JavaBlend. JavaBlend helps programmers write database aware Java applications by mapping database records to objects.

O'Reilly is sponsoring an Open Source Town Meeting on Friday, August 21 from 5:00-6:30 pm at the Fairmont Hotel in San Jose, CA. Admission is $10. Proceeds go to the Free Software Foundation. The Open Source Town Meeting is for software developers, corporate IS managers, entrepreneurs, and others who want to take advantage of the open source development and business models. A panel discussion on "Open Source is Open for Business" will be moderated by Tim O'Reilly, and feature Larry Wall, James Barry, Jim Hamerley, David Filo, Richard Stallman, Bob Young, Brian Behlendorf, John Ousterhout, Jordan Hubbard, and Eric Raymond.
Sun's also published an initial proposal for adding Euro support to Java 1.1.7 and beyond. This isn't a major change and shouldn't affect anyone who doesn't need Euro support. Mostly it involves changing the interpretation of a dozen or so code positions in Java's understanding of Unicode.
Alphaworks has also updated the Skij Scheme interpreter with extensions for constructing and working with Java objects to version 1.1. Skij can be thought of as a scripting language for Java. Version 1.1 of Skij allows access to non-public fields and methods of Java objects, when used in conjunction with Java 1.2.
JavaWorld reviews the state of Java on the Macintosh as well as the recent MacWorld panel on that topic I participated in.
The Electronic Frontier Foundation has proven something cryptographers have been claiming for years: It is possible for less than a million dollars (specifically $220,000) to build a custom computer that cracks DES by brute force fairly quickly. EFF has built such a machine and used to win RSA Laboratory's DES Challenge II in less than than three days. Duplicates can probably be built for about $50,000 and component costs are going down. Complete technical details are available in the just published book Cracking DES: Secrets of Encryption Research, Wiretap Politics & Chip Design from O'Reilly & Associates. (Amazon and the other online booksellers do not appear to know about this book yet, but you can check this link to see if they've gotten it. )
If a small non-profit can crack DES, so can your competitors. So can terrorists. So can organized crime. So can foreign governments. And most certainly so can the U.S. government. This proves that the NSA has been routinely breaking DES encryption for years as has long been suspected. 56-bit encryption is now officially a joke, and 56-bit encryption is about 64,000 times stronger than what can be easily exported from the U.S.
Sun has reported net income of $273 million ($0.69 per share) for the fourth quarter of fiscal year 1998, up from $237.2 million this time last year. This includes a $15 million one-time acquisition charge. Quarter revenues were $2.9 billion, a 13% improvement over this time last year. For the fiscal year, Sun's total revenues were $9.79 billion for the year (a 14 percent gain over FY 1997) and net income was $762.9 million (essentially even with the previous year).
I've updated the notes for Week 4, More Objects, of my Introduction to Java Programming course.

John Ousterhout's Scriptics hopes to make a few bucks by bringing TCL into the corporate mainstream.
It is based almost entirely on the JDK1.2beta3 source code; only 12 source files were changed, and many major bugs from 1.2beta3, claimed to be fixed in 1.2beta4, are _not_ fixed in the early release. Amoung other bugs, bug 4125538 (URLConnections don't work with keep-alive) and 4091084 (SystemColor.get[Red,Green,Blue] return bad value) are still broken.Other informed sources say that this release is based on Sun's JDK 1.2 beta 3H reference implementation whereas the standard JDK 1.2b3 is based on a slightly later JDK 1.2 beta 3N reference implementation.
However, according to the documentation, they've made (finally) major revs to the internals of the JVM. Changes include:
- Object references now point directly to the heap memory for the object, rather than going indirectly through a handle. This removes a level of indirection for all object references (a big win).
- Exact garbage collection (previously, garbage collection was conservative).
- Generational garbage collection (should be much faster).
- Faster synchronization (my tests show it to be about 6 times faster)
- Assorted improvements to the JIT compiler.
Netscape has posted the first preview version of Communicator 4.5. Version 4.5 focuses on bug fixes and ease of use enhancements. There aren't any major new features or HTML tags. There do not appear to be any changes to the Java support. This release expires October 15.

Harlequin has released the first commercial version of Apple's object oriented Dylan language for Windows 95, 98 and NT. According to the press release, "Dylan provides a combination of powerful object facilities not found in any other single language. Dylan source code is substantially cleaner and easier to understand and maintain. As a result, it enables organizations to save money by dramatically decreasing development time and reducing the size of their programming teams." Now, where have I heard that before? The personal edition is freely available. There's also a $249 professional version.
The W3C has released a new draft of the HTTP-ng Architectural Model.
I've made some minor updates to the notes for Week 11 of my Introduction to Java Programming course, Threads.
There wasn't a great deal of Java news at the show. Blue World announced that a new cross-platform, Java based plug-in architecture will be included in version 3.0 of their Lasso Filemaker-Web integration product which should be available in the third quarter. Apple was demoing the latest version of MRJ 2.1 in the developer section of the show floor. MRJ 2.1 will support Java 1.1.6 and includes lots of bug fixes and speed improvements, especially in threading and the AWT. However, it probably won't be ready in time to be bundled with MacOS 8.5 in the fall. Other than that, there really didn't seem to be a whole lot of interest in Java, though.
Alphaworks thas also relesead a bug fix for distributed version of InfoBus tt fixes a NullPointerException during installation if DB2 is not installed. If you aren't having a problem, you don't need to update.
I'll be at MacWorld NY today (Friday). At 2:00 P.M. I'll be participating in a panel discussion about the state of Java on the Macintosh.

This version updates various tools and libraries, including JBindery which has a simplified user interface.
Sun's also posted the first beta of a Java Naming and Directory Interface (JNDI) based RMI registry service provider. that allows programs to access the RMI Registry using a generic naming interface. Furthermore, the RMI Registry can link to JNDI- accessible directories like LDAP to provide location-independent access to remote objects.
Sun's released HotJava 1.1.4. This is a maintenance release with assorted bug fixes and improvements in memory management and HTML display. The previous version was 1.1.2. 1.1.3 was never released to the public.
I've made some minor updates to the course notes for Week 8 of my Introduction to Java Programming course, Windows, Layout Managers, and Dialogs.
