jg21 writes "LinuxWorld has an interview with Sun's head software honcho John Loiacono which provides an opportunity to gauge Sun's intentions with regard to Linux in particular, open source in general, and where Solaris fits in. In spite of the assertion "Sun was founded on the principle of open source. We have contributed more lines of open source code than any other entity on the planet except for Cal Berkeley," Sun seems to view Linux somewhat grudgingly, judging from Loiacono's tone: "Linux is something that we'll have to interoperate with because it may exist far beyond whatever Solaris turns out to be." An important read, if only because a Windows-free Loiacono notes that he's been using the Linux-based Java Desktop System for a year. "It is not perfect by any means," he concedes though. Refreshing honesty from Sun's top software exec."

ajs writes "In November 2002 everyone who wasn't Red Hat was gathering behind a banner that many thought would spell the beginning of a new chapter in the Unix Wars. That banner was called United Linux. Much has changed in the Linux world since then, and some Founding Partners in the United Linux camp have decided that there are other ways to change the market. Thankfully there are more level headed members of that group. Today, we're not so focused on the differences between Linux distributions, Sun's rants, the aforementioned lawsuits and ever-present, market-gobbling Microsoft keep everyone focused and united enough as it is, and United Linux has begun to fade into memory. So what has United Linux done? Well, it unified three distributions at least, focused attention on Linux standards and made hardware vendors feel a bit less lost when writing drivers for Linux, so it wasn't all a loss. Alas, according the the United Linux site, "There are no plans for a version 2.0 at this time.""

SexyFingers writes "Sun released Java 1.5. The non-API stuff that they've added made it finally "catch-up" with C# - since both languages are built to support OOP from the ground-up, their constructs become almost identical as additional OOP "features" are supported. So if you're doing C# and your foundations in OOP are rock-solid, there really isn't any difference whether you're coding C# or Java."

Here's the list of enhancements to the Java Language:

1. Generics (C# 2.0 already supports this)
2. Enhanced For-Loop (the foreach construct in C# 1.0, duh!)
3. Autoboxing/Unboxing (C# 1.0 already has this, everything is an object, even the primitives - not really, but they do it so well...)
4. Typesafe Enums (again C# 1.0 already implemented this, but I think they've added a little bit more twist in Java, that its actually a better implementation)
5. Varargs (C# 1.0's params construct, ellipsis construct in C++)
6. Static Import (I don't know if C# 1.0 has this, or C#2.0, but C# has a construct for aliasing your imports - which is way cooler. Static Import, actually promotes bad coding habits IMHO)
7. Metadata/Annotations (this is C# 1.0's Attributes, Sun's upturned noses just gave it a fancier name - also, C#'s implementation is better and more intuitive)

They've beefed up the API some, and integrated several packages with the regular JSDK that used to be a part of a separate package or installation ---in my NSHO, the Java API has become bloated...

At this point (even before Whidbey) the deciding factor (as always) for Enterprise work, when choosing a language platform, should be the support it has behind it, in terms of IDE, tools, api, and longevity of the vendor pushing it (forget the OpenSource crap argument, those guys are too in love with Perl, Python, and Ruby - Java could become the child nobody wants to talk about if Sun dies) - right now that's C# and the .NET Framework ---

If you ask Paul Graham though, both language would be utter crap and fit only for idiots :) http://www.paulgraham.com/gh.html [I'm exaggerating, so hold off on those flames.]

jg21 writes "After Java 5, what will become of Calvin Austin now that he's lead engineer - and spec lead - in charge of J2SE on Linux? This interview shows him to be Sun's most personable developer asset after James Gosling. (Gosling BTW, who famously uses Mac OS rather than a PC, has a Linux box and uses the X support on OS X to run Java 5.) Asked what feature in the new Java edition he considered coolest of all, Austin without hesitation replied "Metadata" - the spec lead for that particular feature, Austin's former colleague at Sun Joshua Bloch, was headhunted recently by Google. Now Java, Linux, and Google would be quite a combo. Maybe that's what's fueling all the recent speculation that a Google browser would probably be a browser, feed reader, blog tool, desktop search, online search, gmail, news reader, photo editing, and online photo publishing all rolled into one."

An anonymous reader writes "In this essay titled, inevitably, "SUNset?" an analogy is drawn between the car industry in Detroit, which failed in the 70s because the execs looked out their windows and saw nothing but American cars and so missed completely the threat from Japanese companies, and Sun Microsystems. "Sun is going to fail in this decade if it does nothing but send out surveys to customers asking them to validate marketing phrases of Sun's creation," says the author. He adds: "If you are someone who never gets tired of hearing 'proven,' 'best-of-breed,' 'cost-effective,' or 'taking the surprise out of business solutions,' then contact Sun and demand as much of their current marketing material as they can muster." But it isn't just Sun, surely. This is a failing of technology marketeers in general. Hmm, doubtless we can all come up with our own examples far equally awful as these from Sun. Who can come up with worse?"

sympleko (Matthew Leingang) writes "In Volume I of The PHP Anthology, Harry Fuecks showed some of the basic PHP functionality to solve a few simple problems, including how to object-orient your code, how to use PHP's hundreds of built-in functions, and how to use well-developed existing classes, be they from PEAR or other sites. In Volume II, he intends to 'blow your socks off by tackling some traditionally complex problems with the same principles--to great effect.' It's summertime and I'm sandals-only for the time being, so my socks remain safely in the top drawer. But the volume is nonetheless exciting." (Read on for the rest of Leingang's review, and check out last week's review of Volume I.)

There are seven chapters in this volume, each dealing with real-world problems. Many problems are those you've seen solved on sites you admire and wondered "How did they do that?" Others are frameworks that allow your site to run smoothly, with nobody getting accidentally logged out or having to wait too long while your script gluttonously pulls the same data out of the database for the Nth time. At the end, Fuecks goes back to the beginning, to show how proper design and development can save you time when you start your next project.

Chapter 1: Access Control
Authentication is the process by which users identify themselves. This is difficult in HTTP, a stateless protocol in which the server handles one request at a time and instantly forgets you. Luckily HTTP allows cookies, which are bits of data the server sends to the client for to reveal upon revisiting. At first cookies were used only to annoy ("Hello, Steve! You have visited this page 3 times"), but a cookie can hold the ID of a session record in a database, which contains any state-information that you like.

You can authenticate without sessions via HTTP server configuration, as long as you like the dull dialog box the browser pops up when users enter a restricted area. Oh, and you don't mind the fact that users won't be able to "log out" without quitting their browser, nor can you force a logout after a certain timeout value. Nor can you allow users to register themselves... these are all existing, solved problems and the author shows some of the best solutions. Common tasks like allowing users to change their passwords, recover their passwords if (I mean when) they forget them, and arranging users in groups to which you assign common permissions are also covered.

My favorite example from this chapter is the humans-only registration application. Remember when online voting for the Major League Baseball All-Star Game first started? Anyone who knew how to write a web client could have automated a task to vote as many times as the server could handle, and have his favorite players be the all-star team.* To bring it closer to home, what if somebody decides to bog down your site by automatically registering a huge number of times and filling up your database? You can keep these things from happening by making users look at images which contain text but are hard for computers to "read." PHP is in use at all stages of this game, from writing the registration form's HTML to generating the obscured image on-the-fly.

Chapter 2: XML
XML is a fact of life and, hype aside, is a great way to store and transmit machine-readable data. One of the most visible applications is the thousands of bloggers and news sites providing XML feeds of their headlines. You can write portal sites that grab these headlines, parse them all and present them on your site with links to the full text at the source.

There are two ways to parse XML: with events, or by using the Document Object Model (DOM). The methodologies are similar to reading a plain-text file line-by-line or all at once. Using events you can implement a finite-state machine based on which tags and text come down the pike. Or you can slurp the whole document into memory and find any part of it with ease. The built-in library for the former is based on the popular Simple API for XML (or SAX; don't you like those nested acronyms?), while the latter often uses Xpath to find the particular document nodes you want.

The author shows how to parse RSS feeds with both SAX and the DOM, and how to render a feed with DOM. Further, you can use Extensible Stylesheet Language Transformations (known as XSLT) to transform XML -- whether it's to XHTML for regular browser reading, WML (Wireless Markup Language) for viewing on mobile phones, or even SQL to communicate with a database.

Another exciting XML application is in the area of web services, in which agents (often but not necessarily web servers) communicate with each other over an XML-based protocol built on top of PHP. The two most popular protocols are XML-RPC (the RPC stands for "Remote Procedure Calls") and SOAP (which used to stand for "Simple Object Access Protocol" but now is just a name). Often-changing information such as stock prices and weather are often offered through web services, but they can also be used as an object API between agents over the network. What's cool about using SOAP is you can publish to clients exactly what services you offer and how they can call them using the Web Services Description Language (WSDL).

Chapter 3: Alternative Content Types
If you've ever printed out a web page that was designed for browser viewing, you know the less-than-desired effect. The navigational elements, search boxes, and banners, while necessary for the web page, are useless once a static copy is printed. Furthermore, you need to extend your site to include users with less-featured browsers, such as mobile phones.

Fortunately, PHP has been taught many languages. PDF is the standard for print-quality documents, and there are several libraries (free and non-free) which allow you to generate them. WML is the HTML of cell phone browsers, in which screen space is at a premium and bandwidth scarce. SVG is an XML application which allows vector-based images like PostScript does. The coolest example, however, uses XUL (the XML User interface Language, not to be confused with Zool) to make full GUI applications that you run through Mozilla. This isn't useful for the outside world where you can't force your users to use Mozilla (sigh), but works well for intranet applications that run on a variety of platforms.

The author also brings up in this chapter an HTML SAX parser he has written. You can process HTML pages chunk-by-chunk and extract the pieces you want. I hadn't known about such a class until I read the book and I'm very excited I know about it now. For sometimes it's necessary to parse a web page meant for humans to read (perhaps to pretend to be a user and automate your all-star voting), and most HTML pages won't validate as HTML, let alone XML.

A good point here is that a well-designed, tiered application will allow you to swap out different presentation classes with little code rewrite. Separating the tasks of extracting the data from the database and presenting to the user in variety of formats is a common task that when done right becomes subsequently easier.

Chapter 4: Stats and Tracking
Once your site is up and running, you'll be interested to know which parts are the most active, and how much traffic you're getting. Into a dynamic page you can obviously insert any logging mechanism, but a great place to put it is inside your site's logo. PHP can send binary data as easily as text. Why would you want to do this?

• The logo is usually on every page (or it should be). You don't have to cut-and-paste code.
• You can serve the image, then use the flush command to send the output on and do extra processing. This way logging doesn't get in the way of page rendering.

There are lots of packages available to collect and analyze data. The author goes through phpOpenTracker which is quite rich in features. There are also ways to collect data on what links users follow to leave your site, and to keep requests from search engines from cluttering your log files.

Chapter 5: Caching
Another possible knock against PHP is that, while it's good to have dynamic pages, some pages are unnecessarily so. This is a waste of server resources to keep rendering the same page anew. There are different ways to conserve.

On the client side, you can use HTTP 1.1 headers like Cache-control and Expires to tell browsers when it's okay to store cached copies locally

On the server side, as can be expected, you have a greater level of control. You can use output buffering to delay sending of output to the browser, then save a copy of the output locally. On subsequent requests, you can serve the file rather than generate the HTML all over again. This can be implemented on a chunk (or block) level, so that you can keep some parts ultra-time sensitive and others not so much. The package PEAR::Cache_Lite can help with this.

Chapter 6: Development Technique
The last two chapters were my favorites of the two-volume set. They are on a higher level of abstraction than the features of PHP's library of functions, or previous five chapters on real-world solutions. After you've reached a certain level of expertise in PHP coding, you being to wonder about the "right" way to do things. The author shows how to use Xdebug to find bottlenecks in your code, as well as a few quick optimization tips (for instance, design your flow control so that the first choice is the one most often taken).

He then discusses the principles of N-tiered design. N is usually 5, but the data layer (usually a database or file system) and presentation layer (usually the browser) are most often handled outside of PHP, so you normally have three levels to worry about:

• Data Access: Getting data from the outside world into your application
• Application Logic: Doing whatever unique thing your application is supposed to do
• Presentation Logic: Forming a response in a format acceptable to your client

Keeping these layers separate and restricting them to communicating through well-defined interfaces allows you maximum flexibility. If you need to change databases (say you just got venture capital money and can afford Oracle now), you can do so only changing one layer. If you want to serve different flavors of HTML, or different markup languages altogether, or binary data, you can do so by only changing one layer. You can even strive for maximum distributability by enabling your layers to "live" on physically independent machines and communicate with XML-RPC or SOAP.

Documenting your code is essential. Anybody who's been programming for over a year has gone back to code he or she's written and thought, "Now what the heck was this supposed to do?" It's even more essential when you write something and wish to distribute it for the benefit of others. You can expect them to grok your code at an even lower rate since they didn't write it the first time.

Luckily, scripted languages like PHP are excellent at parsing text files, including PHP scripts themselves. Using well-defined documentation formats akin to JavaDoc, you can embed documentation in your code inside comments, and use tools like phpDocumentor to extract these documentation blocks and format them as nice, cross-reference HTML. In fact, writing doc blocks before your code is a good way to think ahead about how you want your classes and methods to work.

Unit Testing, one of the most digestible dogmas of Extreme Programming, is an awesome way to test your code for logic errors. You build up tiny test cases (using mock objects to isolate the class you're testing) and build as many as you like. Once you do this (PHPUnit and SimpleTest are two rich frameworks), you keep your tests and each time you add features, you run your test to make sure you haven't added bugs as well.

Chapter 7: Design Patterns
Design Patterns is one of the modern classics in information technology. After having done OOP for a while, you will inevitably get the feeling of deja vu that you've solved a problem before. Not so concretely as "I need a database abstraction layer," or "I need a templating system," but as in "I need a way to create objects without specifying exactly what class they belong to," or "I'm tired of writing so many if statements." Design patterns are common object architectures which can be used to solve common (though unique) problems.

Many design patterns are more suited to state-equipped applications with GUIs, but there are plenty to assist the PHP coder. The Factory Method is a pattern through which an object can create other objects of varying classes. So instead of writing mysql_connect everywhere, then having to change every occurrence of that function, you can abstract all database interaction to a class, then instantiate a database connection through a class method of another class: $db = MyApp::getDatabaseConnection(). This is useful when the connection (not just the RDBMS, but the actual database) you want varies depending on whether you are developing, testing, or going live with your application. Factory methods are also a good way to avoid global configuration variables.

The Iterator Pattern and the Observer Pattern are two others mentioned in this chapter. Iterators are used often in paging through database results. Observers are used to let objects notify other objects of changes in their state. This chapter will make you want to go read the whole Gang-of-Four book if you haven't already.

My biggest beef with the book is that this wasn't presented earlier on, perhaps at the beginning of Volume II. As a climax, it leaves me flat, wondering how the rest of the volume could have been derived from this very cool concept. But most PHP books conclude with chapters on how to extended PHP on the C level, or giant case studies involving massive code dumps, and I'm often not satisfied with them. This is a nice philosophical note to go out on. And there's something to be said for the argument that books like these aren't written to be read cover-to-cover.

Appendices
The book closes with the same indices as in Volume I. Since I don't know the URL of my review of that volume, I'll just copy: You can read about which configuration directives you're probably most interested in (the complete list you can get on PHP's web site), some common security breaches, and how to install PEAR, PHP's version of CPAN. My favorite appendix is the "Hosting Provider Checklist," a great reference for evaluating whether kewlhosting.com is going to give you the freedom and support you need to make a great hosted web site.

This volume was informative, well-written, and inspirational in that it made me want to go out and add cool and useful features to my web sites. Check it out if you can.

*Not really (not that I tried or anything), but they've always been a little bit smarter about it. You get my point, though. This did happen on an ESPN.com Page 2 mascot popularity contest, but they noticed through request headers that millions of votes were coming from the same place, and invalidated all those votes.

Update: 08/04 15:50 GMT by J : At OSCON, Sun reaffirmed that Solaris 10 will be open-sourced. They said it would be one of the OSI licenses, not sure which yet; that this was approved at the highest levels of the company; and (with the expected "we're just guessing" language), it could happen as soon as year's end.

lokedhs writes "Sun Microsystems is coming out with new chips without connectors. According to the article, this will have a lot of advantages: 'Performance, for instance, could greatly escalate because the speed of transferring data among chips and the number of channels for the transfers would increase. Energy consumption could also decline. Just as important, overall costs could fall, because defective chips could be removed like Scrabble tiles.' This technology will also lead to new CPU's without cache: 'The technique could also allow designers to remove the cache--the large pool of memory currently found on the processor--and put it on a separate chip. Caches were integrated onto processors to amplify bandwidth. Adding cache, however, bumps up manufacturing costs, as it greatly increases the number of transistors. With the bandwidth constraint gone, caches could once again be made independent without it having an impact on performance.'"

trifakir asks: "We are running some quite expensive SunFire servers with Solaris 8. In the 'crontabs' of these hosts we have scheduled maybe some hundred odd jobs, which are constrained by multiple factors: dependencies on other jobs, time constrains, CPU and memory usage, network bandwidth, and so on. Obviously this imposes a CSP. On the other hand the number of these jobs, each one of them can take from minutes to hours is growing and we are now experiencing performance problems given the limited resources we have. Of course we have opened the bag-of-tricks with our best *ad-hoc* solutions, using mostly Open Source software, to turn our system into an event-based and less dependent on the scheduling expertise of the admins. At certain point we were considering using AutoSys and I was looking for a grid-like scheduler like OpenPBS, both of which were discarded for various reasons. I am curious, how you guys, would solve this problem, which seems very trivial for many environments. Both advice about theory (scheduling) and practice will help us and any other readers who may be tackling this difficult problem."

Of course we have opened the bag-of-tricks with our best *ad-hoc* solutions, using mostly Open Source software, to turn our system into an event-based and less dependent on the scheduling expertise of the admins. At certain point we were considering using AutoSys and I was looking for a grid-like scheduler like OpenPBS, both of which were discarded for various reasons. I am curious, how you guys, would solve this problem, which seems very trivial for many environments. Both advice about theory (scheduling) and practice will help us and any other readers who may be tackling this difficult problem."

Quantum Jim writes "In a move which out-does Netscape's one-version number skip and Winamp's two-numbers skip, Sun has announced that the upcoming Java2 release will be marketed as version 5.0, skipping three-and-a-half numbers. Can version 6.022E23 be far behind? Thanks to David Flanagan for the heads-up."

Interested in a 3D desktop? zoso submitted news about about a project called Metisse, writing "There is working and freely available alternative to the (soon to be released under GPL) Sun Looking Glass 3D desktop ( Slashdot story here) If you have spare CPU/GPU cycles just go download and compile the first publicly available version of this X Desktop. Everything looks nice (screenshots here), has OpenGL support, transparency and all other whistles...."

elleomea writes "According to The Register, Sun is releasing Project Looking Glass, their new GNU/Linux based 3D window managing system, under the GPL during their JavaOne conference (beginning today)." The screenshots of Looking Glass make it out to be very pretty. I'm not sure if I have the spare CPU cycles to power such an environment, but it's sure nice to drool over.

mrp101 writes "Over the past few months (aka year) the future of Java3D has been in question. Not too long ago Apple announced a port to Mac OS X, but still no official update from Sun. A few weeks ago Sun announced that they were going to release the source code and begin collecting comments for version 1.4/2.0. And today they delivered, right before the JavaOne conference. The announcement can be found here(1) and the CVS here(2). The code includes the core scenegraph, the vector math library, and Sun's own add-on utility libraries."

An anonymous reader writes "Sun's Java System Calendar Server connector (Hydrogen) for Evolution 1.4 on Solaris and Linux was GPL'ed today and is now available in GNOME CVS. This follows the recent GPLization of Novell's Ximian Connector (for Microsoft Exchange servers). In related news, the next major version of Evolution (version 2.0) is supposed to be released sometime during the next month, and beta testing have picked up pace. If you have some spare time, you can also give the Evolution 1.5.9 a spin. You can also use jhbuild to build Evolution from CVS (since the binaries are quite old by now). There is also a new project in GNOME CVS, called Evolution Brainread which adds a blog viewer to Evolution. It is not yet quite ready for production use, but looks quite good."

Tarantolato writes "The Eclipse Foundation has released version 3.0 of its open-source Java-based IDE. Eclipse backers like IBM say the program offers not only increased productivity and ease of use, but also a plugin-based architecture for creating 'rich client' applications with the networking capabilities of web-based apps and the persistence and native widgets of desktop applications. The Lotus Workplace platform is already Eclipse-based. Some in the Java community, however, are concerned with Eclipse's use of SWT rather than the standard Swing widget set, and some analysts think that project is part of a 'broader challenge to Microsoft's entire .Net development framework' from IBM. Meanwhile, Eclipse executives are attempting to woo Microsoft into joining the foundation."

An anonymous reader writes "Sun Microsystems has signed a contract with the Ontario Ministry of Education in one of the biggest deals yet for its StarOffice software. It covers 72 public and parochial school boards in Ontario. All will be licensed to use StarOffice 7 on all school-owned PCs. Financial details weren't disclosed but Ontario school officials said the cost is 'minimal.'" Reader Apostata adds that the move "will see the application suite used by 2.5 million students. No word on whether it ships with 'Canadian English' pack ;)"

An anonymous reader writes "Sun and Fujitsu just announced a 20-year partnership to jointly develop SPARC based technology and systems. It looks like the long-predicted partnership that was hinted at earlier has finally come to pass in a much more comprehensive manner than I've heard anyone predict, i.e. not just chips, but a unified range of systems. My guess: Sun drops Ultrasparc III to provide the Throughput computing chips for the low end / web / network stuff, and takes up the Fujitsu provided SPARC64 chips for the high end and workstation market. Will this spark a new RISC renaissance for Sun and Fujitsu? Or is it a last gasp before Opteron / PowerPC / Itanium crush them? I for one will be interested to see what systems and processors come out of this. This could really revitalize the SPARC system market, especially if Sun's work on Throughput computing proves out."

An anonymous reader writes "The second version of Sun's Java Desktop System should be unveiled this week, according to this article. And as part of Sun's effort to entice programmers to its new software, the new JDS software will include the Java Studio and NetBeans developer tools." The JDS is their Linux desktop system.

Tarantolato writes "According to a recent Gartner report, low-end Linux server shipments grew significantly in the first quarter of 2004. Part of this may be due to the comeback of the relational database market in 2003, where Linux growth was especially strong, while Windows growth was weaker. There is mixed news for Sun, who saw growing shipments but declining revenues in Q1 of 2004."

Anon. writes "Linux.com is carrying a pretty damning review of Sun Java Desktop System version 2. JDS seemed to have issues with almost each and every machine the author tested it on, support was quite bad - and to top it all, the software comes with a seven page license document. Something seems to be terribly wrong somewhere - otherwise why would Sun decide to ship JDS with kernel 2.4.19 at this stage?" (Slashdot and Linux.com are both part of OSDN.)

BlindSpy writes "Yesterday, Tuesday May 4th, high-school students all over the U.S. took the first-ever Advanced Placement Computer Science College Board exam based on Java. The exam is given as an opportunity for high-school students to earn college credit in programming. The test is based on whichever language colleges are looking for, which signifies a significant step for Java. In past years, the exam has been based on C++ (1 year) and Pascal (around 10 years)." If you took the exam, what were your impressions?
