Saqib Ali asks: "Apple, publishes the Apple Publications Style Guide, which codifies the way in which Apple documentation uses language. This publication contains information about the specific terms that are used to describe interface elements. It also defines style and usage issues such as how certain terms are used and the preferred capitalization, spelling, and hyphenation of those terms. Some parts of the style guide are excerpted in this chapter to provide quick reference for key elements of the user interface. Whenever you are constructing a language for your application, you can consult the Apple Publications Style Guide to help you to create consistent and usable one. Is there a similar Style Guide for Linux Publications? If not, why not?"

"My interest in this stems from the fact that there is lot of Linux Documentation (including mine) that are not consistent in the style and terminology. So, I would like to propose a creation of a Style Guide for Linux Technical Publication. I think a wiki would be the perfect tool to create this Guide collaboratively. I am willing to host a Wiki @ http://tools.tldp.org (The Linux Documentation Project development server). Is this a good idea? Are people interested in seeing something of this sort?"

Saqib Ali asks: "Over at The Linux Documentation Project there is a lengthy discussion going on about whether to use CSS (Cascading Style Sheets) to improve the presentation of the documents. I support the use of CSS to improve the image/formatting of the document, and improve readability. I understand that content is more important than the presentation, but it can't hurt to improve both. There are others who think we should not get involved the presentation layer, and mainly concentrate on the content. Since, most Slashdot readers are Linux users, and might have visited the LDP once or twice, I would like to poll them on what they think about implementing and using nice CSS for the documents on the Linux Document Project website. I've written a CSS for this purpose that is available here, and some sample documents available in this weblog. Any thoughts? Any pros and cons on using CSS to improve presentation?"

Saqib Ali asks: "A DTD (Documentation Type Definition) defines the document structure with a list of legal elements. DocBook DTD is being widely used in creating Linux related documentation. However I am looking for a XML DTD that is more suited to internal IT documentation, and easy to learn and use. Preferably I would like to use a DTD that can be used with OpenOffice. What DTDs are other Slashdot readers using for for internal IT documentation? I have created documentation using DocBook DTD and hosted them on a Apache Cocoon . Cocoon lets me transform the XML to HTML or PDF. I would like to keep the same backend infrastructure (i.e. Cocoon) but try out other DTDs that are suited for IT related documentation. Any ideas?"

hacker asks: "I have been asked many times over the past few years to support "web-based calendaring" with pilot-link, so people can syncronize their PalmOS handheld devices directly with 'online' calendaring software. The problem is...what calendaring software? I've looked at the various alternatives (PHP iCalendar, WebCal, and about two-dozen others) free and commercial, and none of them really offer a good, powerful, flexible way to integrate the same kind of data that resides on a Palm handheld device. I would write the conduit between Palm and calendaring software. Has anyone actually used a web-based calendaring product they like, and if so, which one, and why? Would the ability to syncronize your Palm handheld with your web-based calendaring software be useful?"

firebirdy writes "The Firebird Project is pleased to announce that the v1.5 release of the Firebird database engine is now available for immediate download. The v1.5 release represents a major upgrade to the engine, which has been developed by an independent team of voluntary developers from the InterBase(tm) source code that was released by Borland under the InterBase Public License v.1.0 on 25 July 2000. Development on the Firebird 2 codebase began early in Firebird 1 development, with the porting of the Firebird 1 C code to C++ and the first major code-cleaning. Firebird 1.5 is the first release of the Firebird 2 codebase. Install packages are currently only available for Windows and Linux but other platforms should follow shortly." This product is not to be confused with newly renamed Firefox web browser, which was also called Firebird for some time.

Saqib Ali asks: "There are numerous SSL based VPNs available in the market. They all offer same basic functionality, but a varied set of features. I am currently evaluating a few of these of SSL based VPN solutions. Compared to a IPsec based VPN, SSL based VPNs are fairly easy to test and evaluate, since no client installation is required for the SSL based VPNs. One way to evaluate is to test all of my applications against the each product. I am also planning to test support for various browsers. I was wondering if Slashdot readers have some suggestion/ideas on what else to include in my evaluation matrix. Are there any features that are a MUST, or things that I should watch out for while evaluating SSL based VPNs?."

leandrod asks: "I am in the process of helping a small software company define the infrastructure for their major client's new system. It is a big country, and it is a medium-sized client planning on going big. We are planning to standardize on Debian GNU/Linux. I am aware I can have IBM Tivoli Maestro for GNU/Linux for production scheduling, and BEA's Tuxedo TP monitor, but they are unsupported under Debian. I am also aware of one or two free TP monitors, but they are either incipient or stagnating. I couldn't find a production scheduler. I know I can do lots with the standard tools, but keep in mind I am targeting a transaction-processing bureau for a big operation with hundreds of thousands of terminals and millions of users, something like a poor man's Wal-Mart, or even Visa. Are there vendors out there willing to support Debian or just GNU/Linux in general? If not, are there free software projects that accomplish the same thing?"

ProfKyne writes "I was excited to read this book when I first noticed it listed as "coming soon" in the Java section of O'Reilly's site back in May. I downloaded and read the sample chapter and waited expectantly for the book to be released. I was hoping that this book would be perfect for me, as nearly all of the Java programming I have done has dealt in some way with database access, though I do not consider myself to be an expert on the subject. The book didn't disappoint; Java Database Best Practices is an excellent high-level guide to writing database-driven applications from Java." Read on for the rest of ProfKyne's review. Java Database Best Practices author George Reese pages 267 publisher O'Reilly Associates rating Excellent for Java programmers moving to J2EE reviewer Erik Price ISBN 0596005229 summary A high-level introduction to writing database-driven apps in Java

What it's about: The book is divided into three sections of several chapters each:

1. Data Architecture - an introduction to database-driven application concepts
2. Persistence Fundamentals - descriptions of the various persistence frameworks for Java application development
3. Tutorials

I should note that the book follows a strange order: the most logical progression for the apparent target audience of this book (developers just getting into J2EE) would be to read Part 1 first, then Part 3, and then Part 2, as the "Persistence Fundamentals" section draws heavily on content introduced in the later "Tutorials" section.

The first section (Data Architecture) introduces some of the concepts that will be covered in greater depth later on in the book, but also contains an excellent chapter, "Relational Data Architecture," on database schema design and normalization. By the way, this is the sample chapter that can be downloaded from O'Reilly's site. In fact, this chapter set itself apart from the rest of the book in that it goes into a great deal of detail on its subject (although obviously an aspiring DBA should probably read whole books dedicated to the topic of relational database concepts). Most of the rest of the chapters in the book is somewhat more lightweight than "Relational Data Architecture." This section also contains a chapter that introduces some of the things to be aware of when managing transactions, including implementation tips on using transactions in JDBC programming such as optimistic locking and the various transaction types (dirty reads, etc).

The Persistence Models section focuses on different persistence frameworks, there is a chapter for each of the following: Persistence Fundamentals, EJB Container-Managed Persistence (covers 1.x and 2.0 models), EJB Bean-Managed Persistence, JDO, and "Alternative Persistence." The fundamentals chapter is where some of the best of the "best practices" of the book are found, and introduces such patterns as the Data Access Object pattern and the Memento pattern in the context of a simple guest book JSP application. The EJB chapters do assume that the reader has a basic understanding of how EJB works, and provides suggestions and guidance on ways to implement EJBs in real J2EE applications. (Don't worry, if you don't know about EJBs, the J2EE Tutorial chapter later in the book provides this.) The JDO section is one of the shortest in the book; I think that it's just such a new technology (in terms of available implementations) that most of the "best practices" are yet to be discovered. "Alternative Persistence" means Hibernate and Castor.

The Tutorials section is definitely not for advanced Java programmers, as it contains beginner-level introductions to the J2EE platform, the SQL language, the JDBC architecture, and the JDO API. If you really don't know anything about JNDI or servlets or EJB, then the J2EE chapter is written for you -- it's not a "how-to" tutorial, but rather a description of the basic concepts. The JDO tutorial is like the J2EE tutorial, introducing the basic concepts such as "the extent" and the filter language used to query for JDO-persisted objects, but I think partly because it's such a new technology, there's not a lot of detail here. You'll still have to read more about J2EE EJB, or JDO, if you decide to use them in a production application. On the other hand, you will learn how to make effective use of SQL queries and the JDBC API (which lets you execute SQL queries from your Java code) from their respective tutorials.

While this is a good start, you will eventually want something more in-depth than this if you are actually implementing a J2EE application (such as a book dedicated to servlet/JSP programming or Enterprise JavaBean development). But I really wish that I had read Java Database Best Practices before tackling these subjects, as it would have helped ease the transition

What's to like As strange as it may sound, one of the things I liked most about the book is that it is relatively thin. In other words, the author gets right to the point and doesn't waste excessive space replicating information that can be found elsewhere. For instance, when describing how to implement a database-independent sequencing component, he incorporates enough code to support what he's saying, but doesn't include page after page of complete code listing, intact with multi-line Javadocs and plenty of whitespace -- just the meat. You can download all of the code from O'Reilly's site in a zip archive (and yes, it does include the Javadocs and whitespace that are wisely omitted from the book). Ironically, the book costs no less than other offerings from O'Reilly that are twice as thick.

Also, the "best practices" in the book are very good and, at least in my case, I was not familiar with some of them, so it was very worthwhile reading. As an example, I myself have recently run into the problem of different sequencing systems on different databases (such as MySQL's AUTO_INCREMENT column type vs PostgreSQL's sequence types). I've worked around it by modifying the application's database calls, but that isn't really a good strategy. Implementing a sequencer at the application level (one of the "best practices") is a much better idea if you're not clustering your application servers and other applications will not be performing INSERTs into the database. On the other hand, if clustering is an issue, then it's probably a better idea to use EJBs, and if other applications will be writing to the data store, then database portability will be difficult in the first place (even with the help of Perl's DBI or PHP's PEAR DB abstraction). Some of the other excellent best practices introduced are the DAO pattern and database schema normalization coverage.

What's to consider The most important thing to know when considering this book is that it really struck me as being appropriate for novice J2EE developers and/or those who are new to database programming in general. First of all, I think it's safe to assume that most people who will be doing anything with databases in Java will be using at least some element of the J2EE platform, and this book makes that same assumption. Java's tremendous success right now is in server-side application development. This means there won't be as much useful information in this book for the folks who are writing, say, an AWT interface tightly coupled to a MS-Access database through ODBC calls. Second of all, the patterns and practices described in this book should be familiar to most people who are already architecting J2EE applications, and are covered in greater depth in other books on enterprise application development.

Having now covered the main consideration, I do have to pick a couple of nits. Firstly, this book does suffer from a few of the editing problems that plague nearly all computer books (yes even the O'Reilly books) in their first printing. It's kind of embarrassing, but even in the sample chapter I found a somewhat bizarre mistake near the end, where a class diagram is drawn up using ERD notation instead of UML. Fortunately, there aren't too many technical errors like this. Another bone to pick was the author's choice to use a hideous scriptlet-heavy JSP instead of a servlet forwarding to a JSP in the small Guest Book application in "Persistence Fundamentals." I know that this is Java Database Best Practices, not Java Model View Controller Best Practices, but scriptlets are both difficult to read and quite frankly scorned as J2EE moves toward JSTL and JSP 2.0. It's a little too bad that View and Controller are mixed up in this example, because the author does an excellent job of explaining how to implement the Model using the Data Access Object pattern.

Finally, I have a feeling this book was named "Java Database Best Practices" for marketing reasons, perhaps to go with O'Reilly's other offering, "Java Enterprise Best Practices". While this is an excellent book about Java database programming, and there are indeed dozens of "Best Practice" tips strewn throughout the book, I think a better name for this book would have been "Java Database Fundamentals."

The summary I didn't want to simplify and rehash the book's "best practices" contents in this review, but rather provide prospective readers with an idea of what to expect from this book. Personally, I got a lot out of the book, but if you've already implemented bean-managed persistence in your EJBs using JDO, then you've probably already gotten past the point where this book is going to be a big help. In your case, it might be worth having around the office if you can get the company to pay for it. However, for those who have learned the Java language and want to get more involved in server-side application development, you're going to want to make sure you're familiar with all of these concepts and this book is the perfect way to get started with that. Where to find more info I'm not going to replicate the table of contents or any of the content in the book, because all of that information as well as the excellent sample chapter are available from O'Reilly's site. I purchased the book from SoftPro Books in Massachusetts (US), a bookstore for computer geeks. This is a good place to peruse the book if you're still riding the fence.

Quoting the front page, the purpose of Alioth is multiple: to provide facilities to free software projects supported by Debian developers, to make it easier for non-Debian developers to contribute to projects initiated by Debian, and to support projects whose goal is to promote Debian or one of its derivatives. Go peer with great wonder!"

Connectix recently released version 6 of Virtual PC, the standard for emulating Windows on a Mac. With version 5, the main feature was Mac OS X compatibility. With version 6, the focus is on better performance and Mac integration. Now -- and this is the honest-to-goodness truth -- I have not seen an actual computer (only images on TV or in magazines) running native Windows in months. For the whole of 2003. I live a very good life. And I don't want to ruin it by running Windows on my Mac unless I have a need to.

My Windows needs are few. I am a perl developer; I work on perl and release perl software. Occasionally, I want to test on Windows. Further, I am a Slash developer, and sometimes our users complain about certain bugs that only show up on certain browsers, so I want to test that on Windows too. And every once in awhile, there is some software I need that is Windows-only.

All of these needs are rare, but when I need them, I need them. Virtual PC has always been helpful to me for these purposes in the past, though it's been slow. So on to version 6.

The first thing I did was upgrade from version 5, and just play around. Everything is noticeably faster. Viewing multimedia is nicer, opening apps is quicker, moving around the filesystem is zippier (I am running out of adjectives here, bear with me).

I was overdue on some updates, so I ran the Windows Update app. They downloaded and installed much more quickly, though I still prefer to download via Mac OS X and drag the files over to Windows.

I updated Cygwin and ActiveState's Perl Development Kit and Komodo, which I use occasionally; they work fine, but are still too slow to be bearable for everyday use, but I would not want to use Windows for everyday use, so it's all good.

Now, on to the new features. Version 6 has a more refined interface for defining preferences and organizing multiple guest PCs (I've got Windows 95 and Windows 2000). You can now mount those PC disk images, which is nice, but only when the PC is shut down. Since I leave the PCs running all the time, to make startup faster (using the Save State feature), I never have much opportunity to mount the disk images. Although, when I did try to mount the Windows 95 PC (more than once), it crashed. It worked fine for the Windows 2000 image.

Another new step toward integration is the addition of some items for the Mac OS X Dock: a Start menu application, and the ability to place Windows applications in the Dock. The Start menu application is nifty; you get the Start menu from your Windows PC, but in the Dock instead. It's more responsive and looks better. The Windows applications in the Dock seems slightly less useful; clicking on them does not bring the application to the front, it only launches it (which I'd just as soon do from the Start menu).

Supposedly, there are some significant improvements to printing, including automatically detecting USB printers. My USB printer, however, is connected via Mac OS X printer sharing on another Mac, and so I can't print to it directly from Windows (at least, not that I could figure out). Instead, I need to print through the host Mac OS X from the Windows OS. Sounds simple enough, right?

To do this, I still needed to use the right driver for the printer, and it wasn't included with Windows, so I needed to install it. I downloaded the drivers from Canon's web site with a Mac browser, and just copied them to the Windows desktop. When I ran the installer, Windows reported an "access violation". Thinking that perhaps the file was not downloaded properly, I tried downloading it via Windows instead. It takes longer, but maybe it will work. But no, I got the same error. It's good to know that Virtual PC maintains the Windows Experience, that these problems weren't Virtual PC's fault.

I pulled out the CD that came with the printer and installed the (somewhat out of date) drivers from there; this time, it worked fine. But then, when I tried to print, and the Virtual PC app hung on "Printing page number: 1", with a spinning pinwheel and an unmoving progress bar. Force Quit was my only way out. I tried several times, as I did with mounting the Windows 95 image, and each time, it hung. When I would start Virtual PC again, I'd get the Print dialog, and try to print again, and it would hang. At least it's consistent.

I finally decided to give up on printing this way, and did direct printing. I plugged my printer directly into the computer, told Virtual PC to use that USB device for Windows, and Windows detected it automatically and set it up for me. After that, printing worked fine.

But, in fairness, none of these problems are related to my normal uses of Virtual PC, and if I really needed to accomplish the tasks of printing or mounting I'd probably be able to figure it out. I just didn't care enough, so I dropped it and moved on to more interesting things.

I have a Kyocera QCP 3035 cell phone. I am going to be on the road some this summer, so I wanted to use it as a modem for my PowerBook G4/867. I got the cable and the Mac OS X modem drivers and scripts (I had to email tech support to get them), and it works fine as a modem, but I also wanted to use the cable to upload contacts and ringers. The problem is, the Kyocera software is Windows-only. Virtual PC to the rescue?

I installed the Windows drivers and software and plugged in the cable. It took me a couple tries to figure out that I needed to select the cable in Virtual PC's Serial Ports preferences (assigned it to COM1), but when I did, the software recognized the phone and everything just worked. I uploaded ringers, I controlled the phone with the software. So now for the contacts.

I converted my contacts from the Mac OS X Address Book vCard export to a CSV file the Kyocera software could read. I dragged the file from the Mac OS X desktop to the Windows desktop. I imported the file into the Kyocera software and synched it with the phone. It worked. There's not much else to say here, which is about the highest praise I could heap on the test.

I was also thinking about using some Windows software I have to control my motorized Meade telescope; but frankly, if I am going to be investing the time into getting the cable and setting it all up to use software like that, I'd rather spend the extra money to get the Mac version of the software. It'd be much better to use.

All in all, Virtual PC does what -- for me -- it should. I can run perl and various web browsers for testing; I can communicate with serial devices; I can even play Windows-only multimedia files.

For completeness, I was going to play around with Bochs, but after reading various reader reviews bemoaning poor performance, and not being able to find straightforward instructions, I gave up.

You may recall, gentle reader, that Microsoft has purchased Virtual PC from Connectix. Does that mean people should invest more into Bochs, or look for alternate solutions? Will Virtual PC mean the end of Office for Mac? I don't really know; but as I am not a Windows user, I don't really care, as long as I can keep using the very few Windows products I need.

The Object Prevalence concept, developed by the Prevayler team, and implemented in Java, C#, Smalltalk, Python, Perl, PHP, Ruby and Delphi, can be a great a solution to this mess. The concept is pretty simple: keep all the objects in RAM and serialize the commands that change those objects, optionally saving the whole system to disk every now and then (late at night, for example). This architecture results in query speeds that many people won't believe until they see for themselves: some benchmarks point out that it's 9000 times faster than a fully-cached-in-RAM Oracle database, for example. Good thing is: they can see it for themselves. Here's an article about it, in case you want to learn more."
