In a new post, Lukas Smith mentions (among other things) an upcoming webcast via the folks over at php|architect covering the best practices of using the opcode cache in your applications.    oin us as we host PHP internals developer, Stas Malyshev (Zend) with a presentation on optimizing your use of PHP opcode caching software, be it APC, Zend Platform, or another.   This talk will cover techniques that you can use to squeeze the most performance out of your cache, such as avoiding runtime includes and conditional class declaration.    Register soon because the event happens this Friday (March 16th, 2007) and there is no cost to attend - but you do have to sign up.

Pierre-Alain Joye takes a look at building Cairo (a vector-based graphics library for PHP) on a Windows system.    While trying to get the cairo (and pimp) PHP binding ready to be released, I finally sit down and port Wez build cscript to cairo. It still needs some cleanup, a nice summary message but it works already. I tested it with Visual C++ Express Edition but it should work with other versions as well.   My next goal is to add the tests (nmake tests) and fix the nmake instal    He describes the process he went through to try to get things up and running, but is still having a few issues and has required a few tweaks to get it working. He also links to two resources: a ZIP of the development libraries and a ZIP ready to use package.

Pierre-Alain Joye ha posted some great news about the Zip PECL package today on his blog - it's finally reached stable.   Zip is stable since two releases. I lacked the time to report it :) Three bugs were important. Once PHP 5.2.0 is out, I will focus on the new features. Write stream support, unicode (php6+ support), pattern based addition/extraction and crypting functions.   The three bugs he mentions were a problem with zipArchive::addFile, comment/cdir problems with new archives, and setting properties in extended classes.   You can check out the homepage for the project here or just view the Changelog for complete updates.

With just a quick, supporting note today, John Lim has posted to the PHP Everywhere blog about the Zend Core download that Zend offers to help make installing PHP and its friends even easier.   I'd like to point out that one of the greatest services to the PHP community that Zend is providing is the free Zend Core for Oracle and Zend Core for DB2. The latest versions install PHP 5.1.6. The little known secret is that these 2 installers are perfect for MySQL as the mysql and mysqli extensions are included in the release.   He also recommends it for the IISers out there because of the FastCGI support built in.

Jim Plush has posted an offifical release announcement about his latest contribution to the PHP community - a debugging tool combining PHP (through the myBIC framework) and the Firefox FireBug extension.   I put together a couple pieces of technology to give the PHP community a debugger/profiler that should make life easier in the "web2.0" world. Are you tired of echo'ing print statements in your ajax calls? Writing to log files? Firing up big ol debuggers just to see what the value of some array is? Well look no further than the new MyBic PHP Debugger.   The tool is a smaller part of his larger MyBIC framework and can do things like writing log files, echo information back out to the screen, and communicate information back out to the Firefox user. There is a standalone version of FireBug that will be posted for those that don't want to have to install an entire framework to use it.   Keep an eye out (here and on his blog) for the links to the release when it's posted. In the meantime, you can check out a screencast [mov] of the package in action or just the screenshots in the blog entry.

Matt Wade has posted a quick item to APress' Inside Open Source blog today mentioning an update to an item he'd previously mentioned - issues with the Zend_Cache module.   One of my complaints was the Zend_Cache did not accept lifetimes on a per object basis, but rather the lifetime was at an application level. I just received notice in my inbox that the issue has been fixed! The change is currently in svn, and should be in the 0.80 preview release. Thanks go to Fabien for the fix.   You can download this latest version of the Framework (0.7.0) from the Zend Framework website.

On DevShed today, there's the second part in a two part series (another excerpt from the "Zend PHP Certification" from Zend) talking about getting the most out of your application and platform through some simple debugging/optimizing tools.   They start off with a look at debuggers - what they're for and a brief mention (high level) of how to use them. Next up is some simple suggestions for optimizing the performance of your application:  Hardware issues Web server issues Avoid overkill Zip it up Database optimizations  They also include a simple recommendation that all developers, looking for performance boosts or not should follow - "keep your code simple".

I'm back, with a very interesting topic too!  Joel Spolsky, ex-Microsoft Manager and software engineering guru has a new essay, How Microsoft Lost the API War that is creating quite a big storm in the blogging communitiy.  Joel posits that the priests in the holy Temple of Microsoft have lost their way, because it has split into two factions, and the wrong faction is winning. One faction worships on the alter of backward compatibility, while the other is led by fervent priests who are proselytizing to raise up the new gods of .NET and Longhorn. Joel suggests that the new gods will cause the destruction of the holy Temple because Microsoft's great victories were built on the altar of keeping customers happy with backward compatibility. Furthermore the old gods of the Windows API continue to grow more grotesque and cruel with the passing of time, driving former worshipers into the arms of the friendlier gods of World Wide Web.  This story sounds extremely plausible. I must admit that i fit the profile of the developer who used to develop on the Window's API, is familiar with COM and Win32 who now develops mostly using PHP and Python. However I continue to develop and maintain Windows apps that keep our customers happy, and we still plan to develop new Windows apps. Some points:  Temple of the Blind? Firstly, Microsoft is still a compelling place to work for to people who feel that they can make a difference. The Temple continues to attract talented people with a Unix background. For example we have the recent hiring of Ward Cunningham, author of the Wiki.  Microsoft is still able to keep talented people like Raymond Chen, and others like him who continue to look after the Windows API, and Longhorn apparently will still give high priority to backward compatibility. Open sourcerers like Miguel Icaza are sufficiently attracted to the .NET vision to stake their careers on Mono. Longhorn and .NET are compelling technologies, so even if Win32 is not so cute anymore, M'soft is providing something that remains very attractive.  What i do see M'soft doing wrong is that they aren't disseminating the .NET runtime fast enough. It remains an optional install in XP Service Pack 2 for example. Also their IE dev team appears to be hog-tied due to political reasons; nevertheless IE remains good enough, particularly when I can embed IE as an activeX control, something I cannot do with Mozilla (AFAIK) - Update: I'm wrong.  Temple of the Spider?  Secondly, people don't merely use a web browser. They run the web browser in the OS.  So let me ask you, if you are using DreamWeaver or HomeSite or Photoshop or vi or emacs or Gimp, how many of you are willing to give it up for a java applet (or whatever your favorite technology is) running in your web-browser? Precisely.  Temple of the Abandoned?  Third, Joel makes the claim that developers are not developing to the Windows API. Well he could be right. But I bet a lot of them are still calling Win32.  If you are using a framework or IDE like Delphi or wxWindows (or .NET or VB) then you certainly are insulated from the Windows API, but that doesn't mean that you're not calling the Windows API all the time. I don't see Borland dropping their Windows version of Delphi at any point in time.   In fact, the fact that many developers are using some form of framework is a compelling argument for Microsoft to enhance the .NET framework to attract developers who are using other frameworks.  Today, not that many students learn x86 assembler, but that doesn't mean that Intel lost the CPU wars. Just because fewer people are learning Win32 doesn't mean Microsoft has lost the API wars, if the frameworks run predominantly on Win32.  Temple of the Lost  Joel even warns you in the beginning that "because I'm talking about big trends, I need to exaggerate and generalize". But you still get sucked in because Joel Spolsky is a first-class writer, in the same order as Philip Greenspun or Eric Raymond. That makes him so persuasive and plausible. But this is not Indiana Jones and doomed temples, but Steve Jobs and reality distortion fields.  Other opinions:  Harry Fuecks (PHP is ASP's upgrade path),  Dennis Hamilton (M'soft is just covering all bases), Robert McLaws (Joel is wrong in 7 points), Oliver Travers (the web is not good enough), One Run-time to Rule them all....

Aaron Wormus is back today on the Zend Developer Zone with another in his "Hidden Gems" series. This time, he takes a look at the "Zend Plumbing", those bits of connective code that help you make your Zend Framework applications work.   The functionality that he covers in this article are some of the min parts that a lot of ZF coders use every day and might not know it:  the Zend class (providing a suite of helper methods) built in Wrapper functions:  loadFile loadClass loadInterface isReadable dump exception  the Zend registry  Each of these is briefly described with some sample code for the loadFile, loadClass, exceptions and the Registry to give you an idea of how to use it all. As always, you can check out the Zend Framework website for all the details on each of these functionality bits.

Sun is working on technology to make it easier to run different languages on the Java Virtual Machine. Called the Da Vinci Machine, the project is being described by Sun as "a multi-language renaissance for the Java Virtual Machine architecture." The project features prototype JVM extensions to run non-Java languages efficiently as well as architectural support.Although many languages besides Java have been implemented on the JVM, including Ruby, the intent is to make the JVM more compatible with other languages, said Charles Nutter, core developer of JRuby, which is a version of Ruby to run on the JVM. "For the most part, almost every language that's more than five years old has some kind of implementation on the JVM," he said. ?The JVM allows programs using it to run on any platform supporting the JVM; it provides hardware and OS independence. Benefits like flexible online code loading and online garbage collection, in which objects are moved out of the way automatically rather than having to be saved manually, are featured.Da Vinci Machine is intended to overcome obstacles like mismatches between a source language's design patterns and JVM capabilities. Because the JVM was designed for Java and Java favors some design patterns over others, implementers can find themselves dealing with these mismatches, Sun said."Specifically, the JVM was originally for Java, and many other languages have features unlike what Java provides. We need to find ways to support those features," said Nutter.Some pain points to running new languages on the JVM include limitations on calling sequences and control stack management, finite inheritance, and scaling problems when generating classes.Nutter pointed out that Java, in being a statically typed language, differs from scripting languages like Ruby, which are dynamically typed. Thus, Java gives the JVM more clues about what code is going to be executed. Ways need to be found to let the JVM make the correct call for these languages, he said. In JRuby, this obstacle is addressed via a piece of code to inspect target operations.Capabilities of Da Vinci Machine are planned for inclusion in the upcoming JDK (Java SE Development Kit) 7, which is based on Java Platform, Standard Edition 7. Sun could not provide a release date for JDK 7. It is not known how many Da Vinci features might actually get into JDK 7, Nutter said.Da Vinci represents an experimental branch, or even a fork, of the JVM, said Nutter. He cautioned that fork in this case is not meant to carry the same negative connotations associated with forking of a platform.Java developers questioned liked the idea of Da Vinci Machine."[Da Vinci Machine] sounds like something I was thinking was going to happen and should have happened," said Daniel Hinojosa, an independent Java developer and a founder of the Albuquerque Java Users Group. "I think there's going to be a race between Java and the Microsoft [CLR (Common Language Runtime)]." The CLR has been likened to a virtual machine supporting multiple languages. "I think Java's a great language, but I think people like to program differently, whether it's a functional language or a scripting language," he said. Hinojosa said has been running JRuby, Groovy, and Java on the JVM.Developer Alex Miller, tech lead at Java clustering technology vendor Terracotta, also agreed with the Da Vinci Machine effort."There are lots of people writing and running dynamic languages on the JVM these days, and there are certain things that are complicated or obscure with the use of [dynamic] languages," Miller said.A lot of dynamic languages differ from Java in that they leverage functions rather than objects, Miller said. Making them work on the JVM requires extra work, he said.Sun's JRuby project, meanwhile, is getting an upgrade. Version 1.1, due within a month, features a full compiler to greatly improve performance, Nutter said.
