Jason Carreira

Jason Carreira: "Some people I know are looking at porting their (very large) J2EE application from using a homegrown OR framework on top of Entity Beans with CMP (without CMR) to Hibernate, and they asked me for some tips. I'm not claiming to be a Hibernate expert, but I've used it on an enterprise product, added features, submitted patches, etc. so I know a bit. Since I was writing this up anyway, I figured I'd blog it. "

Otaku, Cedric's weblog: PHP confessions from a Java fiend (part 2)

Otaku, Cedric's weblog: PHP confessions from a Java fiend (part 2): "When you are putting together a Web site, there are two things you need from a language:
Database access.
Web support.
As far as I can tell, PHP's support for the former is adequate but the Web is definitely its forte."

Wired News: Quit Your Job to Blog, Blog, Blog

Wired News: Quit Your Job to Blog, Blog, Blog: "From now on, the New York web designer will no longer be commuting five days a week to his day job at a Manhattan financial services firm. Instead, he'll be devoting himself full time to building out his blog, kottke.org, a scattered collection of writings and photos on topics ranging from web design to the politics of Girl Scout cookie sales.
As for earning a living, Kottke has a plan for that, too. His readers will support him. At least he hopes they will. Kottke does not intend to seek advertising revenue; he plans to depend solely on reader contributions. "

XML-RPC for Python

XML-RPC for Python: "Secret Labs' xmlrpclib module is an implementation of the XML-RPC protocol. This implementation is tightly integrated with Python, which makes it very easy to call remote methods. For example, here's the Python code needed to call one of Userland's sample servers:
from xmlrpclib import Server
betty = Server('http://betty.userland.com')
print betty.examples.getStateName(41)
This results in a remote call to the examples.getStateName method published by the betty server, with the integer 41 as the single argument. The result from this call is a string with the value 'South Dakota'.
The marshalling and parsing classes provided by this module can also be used in XML-RPC server implementations. Sample code for Medusa and Python's SocketServer module is included in the current release."

Small Values of Cool: The real problem with Java

Small Values of Cool: The real problem with Java: "I've realised what the real problem with Java is, for me. It's not the fact that my productivity is much lower with Java than it is with Python. After all, it's my management that decide that I should be using Java, and if they want to make me less productive than I could be, it's their prerogative.
And it's not the vast raft of tools, libraries and frameworks that a modern Java application uses that bothers me. It's a problem for a lot of people - c.f. Bruce Tate's superb Better, Faster, Lighter Java (on which more later), but I like learning new stuff, so I'm happy.
No, the problem is that Java coding is just no fun..."

Techdirt:Apparently, The Airline Industry Hasn't Learned About Backups

Techdirt:Apparently, The Airline Industry Hasn't Learned About Backups: "It seems that the airline industry has never learned the importance of having backup systems. While that might be okay in some industry, in something like the airline industry, where the computers control everything, having a computer system go down is ridiculously costly. It seems like every few months there's yet another story of an airline (or airport) computer system going down, stranding people, delaying flights and causing all sorts of mayhem. A few months ago it was both USAir and Delta subsidiary Comair, and today United's reservation system went down for a while. "

Struts Flow: Continations come to Struts

techno.blog("Dion"): Struts Flow: Continations come to Struts: "Wow, Struts is a huge project:
Today, Struts is comprised of nine subprojects: Core, Taglib, Tiles, El, Faces, Scripting, Applications, Shale, and (now) Flow.
The Struts team just announced Struts Flow which brings a continuations based approach to web flows.
This is interesting stuff, and we have seen continuations popup in other communities such as Ruby, Perl, and Smalltalk.
Seaside was the first web framework that I saw with continuations, and it intrigued me from the beginning. It really does make sense to have the users 'session' to be the core. In fact, on our projects, we put a lot of functionality there (even if it just ties into the business layers etc).
It will be interesting to see how Struts Flow gets adopted.
Take a look at an example of putting the logic in one workflow, even though web pages are being sent around to get input from the user: "

Customers can configure their local area networks so that the Wireless WAN Connectivity Service automatically activates should the wireline connection be interrupted, thus achieving the truly diverse network architecture that ensures critical applications keep running.
The Wireless WAN Connectivity service uses Digi's Connect WAN GSM wireless gateway. Since EDGE transfer speeds average just a little faster than dial-up, most customers will not want to use it outside of emergency situations."

Setting up a PHP development environment

So now ive done my 'Hello World' stuff, its time to setup a proper development environment, on my windows PC.

Id read that there was a PHP IDE, that ran in eclipse, so had a look at that.

Did a search for php and eclipse, and found phpeclipse.

Followed PHPeclipse installation for Eclipse 3.x

Downloaded eclipse 3.1M5 and set it up to run with j2se 1.4
Downloaded PHPEclipse1.1.3
Downloaded the wamp2.2 Apache, PHP, and mysql distribution
Downloaded and installed the dbg debugger
Downloaded the sql plugin

Where do I start with PHP

So where do I start with PHP.

I went to google, typed in 'php', and clicked on the first link that came up (http://www.php.net/).

Clicked on introductory tutorial, and did a few of the things from the introductory tutorial. Now you may e asking what I ran this stuff on. I still have my linux box that I built, with Mandrake 10.1 installed, and apache, php, mysql all are included in the install.

Developing web stuff with PHP

ive decided to learn PHP!

Ive wanted to learn PHP, and develop a free dating site, and see how far and can take them.

Bit of a diversion from RPG and Java!

So here goes with PHP!

gadgetshop.com - Gadgets and Gifts: "We knew from the moment that we met the Magic Messenger that it was destined to become a household name. After all it's a gizmo that lets you send text messages from your landline� everyone's going to want one! There's no fussy set up involved, you just plug the Magic Messenger into your home phone line, send a registration text and that's you � ready to text until your heart's content � or the cows come home � or whatever. There are lots of features and benefits which make the Magic Messenger really practical, but our favourite has to be the qwerty keyboard which manages to get rid of the only negative aspect of texting in a single go: trying to coordinate your fingers to move quickly over the fiddly keypad. This makes it great for anyone who has found texting difficult to get to grips with because of the layout of the buttons on their mobile phone, while the large LCD makes the texts so much easier to see.

The #2761/#4761 PCI Integrated Analog Modem is not planned to be supported on future iSeries hardware models.

Feature #4800 Cryptographic CoProcessor
V5R1 is planned to be the final release to support the feature #4800 Cryptographic CoProcessor. The replacement for #4800 is the #4801/#4802 Cryptographic CoProcessor, which offers improved performance and 112-bit T-DES (vs. 56-bit DES for the #4800).

ISDN Alternative Solutions, October 2001: ISDN adapters #2750, #2751, #4750 and #4751 will not be supported in future releases of OS/400.

Suggested alternative solutions

Note: ISDN adapters #2750, #2751, #4750, and #4751 have been withdrawn from marketing effective November, 2001.

OS/400 V5R2 supports SPD I/O on the Model 6xx/Sxx/7xx and on the Model 820/830/840 with an appropriate migration tower.
The new, POWER4-based Model 890 does not support SPD I/O nor does it support the attachment of a migration tower. IBM does not intend to support SPD I/O nor migration towers on future iSeries servers.
The iSeries plan for I/O attachment is to use the 1GB High Speed Link (HSL) and PCI. In conjunction with copper and silicon-on-insulator processors, these technologies deliver balanced system performance. Customers implementing HSL and PCI have benefited from increased application availability through improved disk throughput, backup performance and batch run times. Concurrent maintenance of PCI-based adapters and disks can also contribute to increased system availability. Expanded connectivity options are available with HSL and PCI, including 1 GB Ethernet, Fibre Channel, and support for direct connection of Intel-based xSeries servers. The higher density and improved packaging of HSL /PCI towers and PCI adapters can lower operations costs through floor space and power consumption savings.

To take full advantage of iSeries, IBM advises 820/830/840 customers who still use a migration tower and SPD-attached I/O to transition to HSL-attached I/O. To help with this transition while leveraging customer investments in I/O towers, disk drives and other selected I/O, on August 28, 2001 IBM extended options to convert SPD-attached #5065/#5066 PCI I/O towers to HSL-attached #5074/#5079 PCI I/O towers. This I/O tower conversion can also simplify SPD-attached to HSL-attached I/O migration for iSeries customers.

To best preserve migration options when moving to HSL and iSeries processors without migration towers, 6xx/Sxx/7xx customers adding new I/O should use PCI features in the upgradeable #5065/#5066 SPD-attached PCI I/O towers. The 6xx/Sxx/7xx can not support HSL-attached I/O towers.

5722-SS1 WORKSTATION GATEWAY, September 2001:
V5R1 is the final release to support Workstation Gateway, which is part of TCP/IP functions of OS/400. If you are using Workstation Gateway today, you need to migrate to the IBM WebSphere Host Publisher product, which will be part of the Client Access Family (5722-XW1) as of September 28, 2001. WebSphere Host Publisher provides XML Legacy Gateway---a customizable Web-based 5250 interface function--that has the same functionality as Workstation Gateway.

For more information about WebSphere Host Publisher as part of the Client Access Family, refer to the April 23, 2001 Software Announcement 201-113 at:
IBM iSeries V5R1 Programs Improved

For information on how V4R5 and V5R1 Client Access Family customers can acquire the WebSphere Host Publisher product, refer to August 28, 2001 Software Announcement 201-237 at:
Function Added to IBM iSeries V5R1 Software

5722-XE1 - MAPI SUPPORT IN CLIENT ACCESS EXPRESS FOR WINDOWS, September, 2001:
V5R1 is the final release that the Message Application Programming Interface (MAPI) function will be available in Client Access Express for Windows. MAPI is a set of program interfaces used by mail applications but are now becoming obsolete. Some customers may still use MAPI because it ties directly to the system directory (SDD) for storing user information. For those customers, it is recommended that they migrate from using SDD to using LDAP as a directory solution.

Publishing directory information to LDAP can be easily accomplished through the use of iSeries Operations Navigator. By right-clicking on a system name, and choosing "Properties", you can go to the "Directory Services" tab to select user information to publish. Within minutes, the user information is published to LDAP. For more details, refer to the Synchronize System Distribution Directory to LDAP (QGLDSSDD) API in the Information Center.

The LDAP Web site at www.ibm.com/eserver/iseries/ldap also has information on LDAP and publishing.

OPEN CLASS LIBRARY, August 2001:
The Open Class™ Library shipped as part of WebSphere Development Studio for iSeries (5722-WDS) and Operating System/400® for iSeries (5722-SS1) are provided for one additional release beyond V5R1, after which it will be discontinued. The I/O Stream and Complex Library continues to be shipped and supported as part of Operating System/400 (5722-SS1).

All applications that use the Open Class Headers and Service Programs need to be refreshed using the C++ Standard Library provided with 5722-WDS and 5722-SS1.

When discontinued, IBM Open Class Headers shipped in library QSYSINC with a descriptive text of "IOC HEADER" and the IBM Open Class Service Programs, QYPPOC370 and QYPPOC510, shipped in library QSYS will be removed.

To assist migration from IBM Open Class to the C++ Standard Library, refer to the following file.

monitoring all the HTTP headers

BruceBlog: "First of all, finding a proxy for Windoze that will capture HTTP POSTs was actually pretty difficult. Then I took a look into what is necessary with Squid to get it to capture HTTP POSTs and quickly abandoned that idea. It's been over six years since I last dug into Squid at any level. I know it's very nice, but I really didn't need a cache either, not while I'm developing. Then I discovered tcpmon.
Buried in Axis, tcpmon is a lightweight Java proxy that captures all traffic including HTTP POSTs. And because it's written in Java, I can run it on both Mac OS X and Windoze without any issues. So I've been monitoring all the HTTP headers easily with tcpmon and what I've discovered is priceless. The cookies in these headers are very custom which required some hacks to get my POSTs looking just right. But overall, tcpmon has been a lifesaver. If you ever have a needs for a small but nimble Java proxy, check it out. "

Windows sludge: It's the invisible, undetectable detritus that collects on your hard drive and just mucks up the works. In the past, the clean install of a Windows upgrade could solve in one fell swoop all the little glitches that accumulate over time. But Longhorn's still a ways off, and service packs only go so far. I'll show you how to get Windows 98, Me, 2000, and XP back to their quick and reliable selves. And I'll describe how to toss an unfixable Windows setup and reinstall it from scratch."

alphaWorks : HeapAnalyzer

alphaWorks : HeapAnalyzer: "HeapAnalyzer allows the finding of a possible JavaTM heap leak area through its heuristic search engine and analysis of the Java heap dump in Java applications.
Java heap areas define objects, arrays, and classes. When the Garbage Collector allocates areas of storage in the heap, an object continues to be live while a reference to it exists somewhere in the active state of the JVM; therefore the object is reachable. When an object ceases to be referenced from the active state, it becomes garbage and can be reclaimed for reuse. When this reclamation occurs, the Garbage Collector must process a possible finalizer and also ensure that any internal JVM resources that are associated with the object are returned to the pool of such resources. Java heap dumps are snap shots of Java heaps at specific times. "

Struts best practices

Struts best practices: "Multiple options are available for solving problems with Struts. When deciding among these alternatives, the choice must be based on parameters such as the scale of work and availability of time. However for large applications and the best quality-of-service needs, every decision becomes crucial and extra efforts are required to choose the appropriate solution. To help you make these decisions, Puneet Agarwal discusses some of the best practices for developing Struts-based applications. (2,800 words; September 13, 2004) "

developerWorks : Blogs : Bobby Woolf

developerWorks : Blogs : Bobby Woolf: "There's a lot of different search engine stuff going on, as the rest of this post will show. But before I disappear into that trivia escapade, I should make the point that the effort of organizing and finding stuff on the Web, and getting stuff onto the Web so that it can be found, is big business. 'What�s Next for Google' (MIT Press) argues that the search wars will be the next browser wars and that Google could end up like Netscape (flattened by Microsoft). It explains the need for Google to establish search standards so that search engines can work together, search will become a natural part of applications instead of a separate activity, and no one company will be able to dominate. It's good reading."

Browser speed comparisons

Browser speed comparisons: "There is a speed war on the web. Browsers compete on many fronts; security, standards support, features and speed. Most people are aware of which major browser fails on three of these, but one of them is still open for grabs. Speed.

Many organisations and users try to claim that their browser is the fastest. The Opera site claims that Opera is The Fastest Browser on Earth!. The Mozilla site claims that Firefox 1.0 empowers you to browse faster (faster than what?). Mozilla itself is quoted as being an alternative to Microsoft IE and it's faster to boot. Apple's Safari pages claim that Safari loads pages more quickly than any other Mac web browser (although they failed to show any results for Opera, and their charts fail to show results for pages that contain images). Internet Explorer users often claim that they use it because of its speed, as the alternatives take longer to start and load pages.

Opera and Firefox users are quite vocal on the subject, but none of them can actually show any research to back up their statements, ususally just saying "X takes way longer than Y to start" or "my friend uses X and it is much slower on his computer than Y is on mine". Those that did try more than one usually say "X just felt faster than Y when I tried them" (although this may refer to familiarity with the individual user interface - something that I do not cover here). I have even heard people comparing Firefox and Opera, then realised they were referring to Opera 6 (even though historically, Opera 6 is about equivalent to Netscape 4), something that was replaced with a completely new engine long before Firefox even existed.

Well, I've had enough of these unfounded arguments. I present my research. This is an honest, unbiased view (or as unbiased as I can be). Unlike most people, I not only test all the browsers, I test them all on the same computer as each other - grouped into Linux, Mac and Windows (using the same or equivalent hardware for each). This, I hope, gives an accurate comparison, not only of the browsers compared with each other, but for those that work on multiple platforms, it also gives a fairly accurate comparison of the different optimisations for each platform.

Sadly, these DBAs don't understand how brilliant your framework is in automatically generating queries for you, and how flexible it makes your application. They feel that with the database being your application's primary bottleneck, you should have complete control over SQL queries, so that they will be able to analyze and tune them for performance."

Creating a Web site the easy way with WebSphere Studio Web Site Designer and page templates

Creating a Web site the easy way with WebSphere Studio Web Site Designer and page templates: "Overview of Web Site Designer and page templates
Page templates are one of the new features of WebSphere Studio Web Site Designer. With page templates, you can:
Manage common contents of multiple Web pages, such as header and footer sections, with a separate file called a page template file.
Manage layouts of multiple Web pages.
Update a group of Web pages simultaneously and automatically, simply by updating a page template and saving it.
When you create a page template and also create multiple Web pages to which the template applies, page template's updates are immediately applied to all of the Web pages as soon as the template file is saved. The template file and Web pages have special comment tags that define common or page-specific regions in the content. You can put the comment tags anywhere in the template. And you can use page template with both static and dynamic Web pages.
With Web Site Designer you can:
Define Web site architecture using a graphical diagram editor.
Change information simultaneously on multiple pages, including stylesheet, page title, keywords, or page template.
Generate navigation links (nav bar) on each page that reflects the Web site structure you created using the Diagram Editor. Nav bars are updated automatically when you update and save your Web site structure.,
Generate a site map that reflects the Web site structure.
While Web Site Designer has other useful functions to manage Web site, this article focuses mainly on dynamically generated nav bars. By using a nav bar and page templates together, you can create multiple pages with consistent layouts, common sections like a header or a footer, and dynamically generated nav bar links.

What to do if WebSphere Studio hangs

What to do if WebSphere Studio hangs: "Introduction
Tools and applications sometimes hang (do not respond to any mouse or keyboard input) because of an infinite loop, deadlock, or other problem. IBM � WebSphere� Studio Application Developer (hereafter called Application Developer) is no exception. This article shows you how to identify the component where the hang occurs and determine whether it is due to user error, programming error, or a bug in the product. (Screenshots below are from Application Developer V5.1).
A technique provided by the Java JVM
The Java� JVM provides the means to produce a javacore at the activation of a combination of keys: pressing Ctrl-Break (on Windows) or Ctrl-\ (on Linux) produces a Signal which will cause the JVM to take a snapshot javacore. The program will continue running unimpeded otherwise. The technique to localize the hang is to produce a few snapshot javacore files and analyze them. We will provide two examples, one in a simple standalone Java program environment, another one running in the Application Developer environment. In both cases, once the program hangs, there is need to press Ctrl-C to terminate the program."

WebSphere Application Server Web server plug-in

What is the WebSphere Application Server Web server plug-in?
The IBM® WebSphere® Application Server Web server plug-in is the “glue”
between a Web server and WebSphere Application Server. The primary
responsibility of the plug-in is to forward HTTP requests from the Web server to
the WebSphere Application Server. The plug-in is shipped along with a
WebSphere Application Server installation CD and is comprised of a native
library. Although the plug-in code varies with the Web server type and the
operating system that it’s running on, its overall functionality remains the same.
Who should read this document?
This is a technical paper intended for audiences such as application developers,
architects, system administrators or anyone wanting to understand or debug the
plug-in. Although this paper has been written and tested for WebSphere
Application Server V5, it will be very useful for Version 4 users as well.
This paper puts special emphasis on understanding and rectifying failure
situations related to the plug-in, especially such failures which are caused due to
overloaded or hung systems.

To this layer you can add a presentation layer (CSS) and a behavior layer (JavaScript) to make your website more beautiful and user-friendly. These three layers should remain strictly separate. For instance, it should be possible to rewrite the entire presentation layer without touching either the structural or the behavior layer.
Despite this strict separation, the presentation and behavior layers need instructions from the structural layer. They must know where to add that touch of style, when to initiate that smooth bit of behavior. They need triggers."

February 4, 2005

Communicating with website users via email is crucial to the success of any online service. The ability to deliver registration confirmations and newsletters, provide a convenient and relatively secure password recovery tool, and keep clients updated with shipping status reports are just a few of the reasons for incorporating email-based features into your website infrastructure. In this tutorial, I'll show you how to incorporate email delivery capabilities into your PHP applications via both its native mail command and a great third-party extension called HTML Mime Mail. I'll conclude the article with a few pointers regarding how to most efficiently carry out bulk email delivery."

Stylish Buttons - WebReference.com-

Stylish Buttons - WebReference.com-: "Until recent versions of IE and Mozilla, buttons were simple slabs that looked like bricks in a polished design. Now they're at least rendered with rounded corners, and with a shadow and rollover effect. Still, you're stuck with anonymous black-on-beige, and the size is almost always too big for the page. If you're going to the trouble to control everything else, why stop when it comes to form buttons? Why not tweak them"

What Is A CMS?
A Content Management System (CMS) allows you to add, edit or delete content to your website without having to create and format the pages manually. All the pages get generated on the fly, the CMS application picks the template, adds the headers and footers, generates the menus and blocks for your page and then automatically renders the page. As an example, when I wanted to add Google ads to all the pages of my CMS site, I created a block with the Google Adsense code. When I activated it, it automatically appeared on all my pages. If I had to do this page by page, it would have been a nightmare (since my site contains thousands of pages)!
The main reason people hesitate to use CMS is because they think a CMS site will not perform well with search engines. But when used properly, CMS can actually help with scoring points with the search engines. This article shows you how."

CSS: Cascading Style Sheets Made Easy - WebReference.com-

CSS: Cascading Style Sheets Made Easy - WebReference.com-:
"HTML was originally intended to be used to define the content of a document using tags such as h1, p, table and the browser was to take care of the layout without the use of formatting tags like font. As the major browsers (Internet Explorer and Netscape) continued to support more tags it became very difficult to create Web sites where the content was separated from the presentation layout. In other words, the design and content became intertwined making it difficult to make changes. The W3 (World Wide Web Consortium) created styles in response. Most modern browsers now support CSS so its safe and easy to use. CSS can save you a lot of work when designing a website. Instead of having the same styles in the head tags you can have an external style sheet to control the layout and styles of the whole website. This means you can change many elements of the entire website by changing one file!"

Linux Magazine | April 2003 | FEATURES | Watching the Eclipse: "Eclipse As Application Framework
At first blush, Eclipse appears to be 'Just Another Java IDE', but Eclipse is really designed to be an application framework. Eclipse includes high-level concepts like workspaces, wizards, viewers, editors, resources, and, of course, plug-ins. These concepts can be used to create your own state-of-the-art IDE or your next business application."

Rapid Template-Driven Development with Jakarta Velocity

Rapid Template-Driven Development with Jakarta Velocity: "Here is where Jakarta Velocity comes in�making it so you can have 'active' Web pages, but where the design and the implementation details are kept neatly separate through the use of templates. Using Velocity, a designer can design a page and put inactive placeholders on the page that the developer will use to activate the page. You'll see this by example a little later. It should be noted that this isn't the only use for Velocity�it is in fact a generic template engine that can be used for outputting any kind of text, but Web pages are obviously a very useful example.

ONJava.com: Eclipse Plugins Exposed, Part 1: A First Glimpse

ONJava.com: Eclipse Plugins Exposed, Part 1: A First Glimpse: "This new monthly column is about writing plugins in Eclipse. Who is this column for? Many Eclipse users simply use the IDE out of the box without needing customization. Many will be using plugins made by other people. That is not the target audience of this column. Some Eclipse users will want to customize it. Some will develop tools for their company's employees. Some will want to sell tools that connect to their products. Some will want to resell Eclipse under another name with these tools pre-installed. These people constitute the target audience. The prerequisites for starting to write Eclipse plugins are knowing how to use Eclipse and write Java programs, and having a good understanding of the Standard Widget Toolkit (SWT) and Swing."

[the downside]: "Singletons are evil. Douuuugh. How do you test a singleton ? Worse: how do you test a singleton that requires an HttpServletRequest to initialise ?
Know what is out there! . I can't believe they wrote a Connection pool themselves...
It is good to use a web framework. But it's bad to pick an unknown, buggy, immature framework (sorry...no names here) that was developed by someone who went the 'not invented here' road.
Tight coupling of business logic to the web framework, the Servlet API, the Singletons, the DB, the everything. Again: how do you test this ?
Code to interfaces, not to implementations. I see private ArrayList foo, private HashMap bar all over the place "

Terse Systems : A good JSP editor

Terse Systems : A good JSP editor: "This is the story of how I found a good JSP editor.
Code completion is the killer feature for me. It's the reason I moved from Emacs to JBuilder, and from JBuilder to Eclipse. Code completion means less syntax to think about, and more attention to devote to code. So it came as a shock when I started putting JSP together and found out that 'ctrl-space' didn't do anything in Eclipse.
I had a list of specific features though:
Must support custom tag libraries.
Must complete tags and attributes of tags.
Must support embedded Java syntax.
Must complete methods and recognize Java classes inside <% %>.
Must validate Java expressions for syntax and missing variables.
Must not crash, hang or install crap onto IDE.
Not too complicated, right? I want a JSP editor and just a JSP editor. No autodeployed J2EE applications. No fancy GUI. No 'debug on the fly' feature. In short, no crap."
