Building a Tree From Database Data
Employee +0 Vote Up -0Vote Down

Hi all,

Today I'd like to continue a blog series in which I highlight Web application tutorials for NetBeans 6.5. A few changes have been made to tutorials, among which is the featuring of MySQL as the database of choice.

This fifth entry in the series will cover the tutorial, "Building a Tree From Database Data".

This tutorial shows you how to dynamically build a tree structure from data in a database. Using NetBeans IDE 6.5, you build a two-page application, the first page of which includes a JSF 1.2 (Woodstock) Tree component. You populate the first-level nodes in the Tree with names from a database, and the second-level nodes with the trips for that person. The trip nodes are links to a second page, which displays

Hi all,

Today I'd like to continue a blog series in which I highlight Web application tutorials for NetBeans 6.5. A few changes have been made to tutorials, among which is the featuring of MySQL as the database of choice.

This fourth entry in the series will cover the tutorial, "Using Databound Components to Access a Database".

In this tutorial, you use NetBeans IDE 6.5 to create and deploy a web application that displays master-detail data from a database that is packaged with the IDE. In the application, you select a person from a JSF 1.2 (Woodstock) drop-down list, and the application displays a table that shows all the trip records for that person.

MySQL is the database used in this version of

Hi all,

Today I'd like to continue a blog series in which I highlight Web application tutorials for NetBeans 6.5. A few changes have been made to tutorials, among which is the featuring of MySQL as the database of choice.

This third entry in the series will cover the tutorial, "Developing a Visual Web JSF Application".

In this tutorial, you use the NetBeans IDE and JSF 1.2 (Woodstock) components to create and run a simple web application, Hello Web. The example application asks you to input a name and then displays a message that uses that name. At first, you implement this page with an input field. Then you replace the input field with a drop-down list from which the user can choose a name. The drop-down list is

Hi all,

This second entry in the series will cover the tutorial, "Creating an Ajax Application with Script.aculo.us", which is based on a blog entry by Arun Gupta.

This tutorial demonstrates the usage of the Java Persistence APIs to implement server side pagination (recommended for large sets of data) and to get and display the results in a text field featuring Ajax functionality. Ajax is a technology that combines (X)HTML, JavaScript, and CSS with the power of XmlHttpRequest in the creation of

PlanetMySQL Update: Goodbye, MagpieRSS, hello SimplePie!

This is more of an "behind the scenes" update and I hope that you won't see any (negative) changes on the PlanetMySQL front page or the RSS feeds: I just finished and commited the conversion of the backend script that performs the parsing and aggregation of feeds from requiring MagpieRSS to SimplePie.

This will provide better support for a wider range of feed types and should also fix a few quirks, e.g. that some postings (for example the one from Kevin

Project Kenai
+0 Vote Up -0Vote Down

Sun is a huge company. So it comes as no surprise that I’m finding out about Project Kenai via Tim Bray, instead of some internal mailing list (believe me, there must be thousands).

Tim’s got a Q&A with Nick Sieger, who’s one of the chieftains behind Kenai. I find it amusing that the comparison is made against Google Code and GitHub - has SourceForge hit irrelevancy? I’m surprised Launchpad isn’t mentioned.

Tomorrow (Thursday, 11th of September) at 9:00 PST/16:00 UTC/17:00 GMT/18:00 CET, there will be an new free MySQL University Session. MySQL University started as an internal training program for MySQL engineers, to share and spread knowledge about their areas of expertise and has been available to the public for quite some time now. It covers a wide range of technical topics around the MySQL Server and usually takes place once per week.

For the first time, the presentation will not be performed by (former) MySQL employees/developers, but by two of our "Sun Classic" colleagues: Jyri Virkki (OpenSolaris Web Stack

Another article on Telecommuting. The Ugly, The Bad and The Good
+0 Vote Up -0Vote Down

Computer World has an article about Telecommuting . So, I thought I’d chip in my inflated $0.02. Telecommuting, doesn’t mean working from home. This is one of the biggest myths, and truths people will realize over time. What makes me such an expert? I’ve been telecommuting for the past 3 years, straight, full time. I’m not talking about moonlighting, and doing part time work for companies who post on craigslist. I’m talking multi million dollar projects. I haven’t been fired, I haven’t left the company, and I’ve been rewarded with a raise, and more importantly, I haven’t missed deadlines.

You still have a job, act like it. (The Ugly)

At NetCAT

During NetCAT, I got a chance to review PHP support, although I had opted for it before-hand, still I just got started last week.

You can read my 4th edition of personal NetCAT Weekly Report. So, Tony and Yudi, reviewed it in early days of NetCAT 6.5, while I was reviewing VW JSF tutorials.

Now, some of them are working, though I gave my personal opinions, what I felt after reviewing. By the way, it was Jan Chalupa’s WordPress Project Tutorial, that got me started finally to review PHP docs and editor support, etc.

Some notes: Joomla! Day Malaysia 2008
+0 Vote Up -0Vote Down

I would’ve written sooner about Joomla! Day Malaysia 2008, but I spent most of Sunday cringed in between the bed and the toilet. Here are a bunch of quick notes I took at the event, with some thoughts tacked on to it.

Overall impressions? It was good for a Joomla! beginner. While I would consider myself a Joomla! beginner, I’ve seen many a CMS and maybe am a tad bit jaded. There is a great amount of interest in Joomla! - about 200 people registered for a paid for event (not cheap either - RM70 for a Joomla! forum member, and RM150 for regular visitors). So there’s definitely money to be made in Joomla! and CMSes in general.

Location? This is the first time I’ve been to the rather infamous Cititel hotel, tacked to MidValley. Held at the 5th floor, I

Why is MSNBot ignoring robots.txt?
Employee +0 Vote Up -0Vote Down

Today, the root file system on our public svn server nearly ran out of disk space. The reason? The /tmp directory was quickly filling up with temporary files created by websvn, which I set up parallel to the FishEye repository browser for testing purposes. A quick investigation of the apache log files revealed the culprit - a crawler from Microsoft was running haywire and decided to ignore the rules in the robots.txt file, even though it did actually looked at the file before!

Here is how robots.txt looked like (I now changed it to disallow everything):

User-agent: *
Disallow: /fisheye/
Disallow: /websvn/

If I am not mistaken, no crawler should actually consider going into the SVN browser directories. Some snippets from

MySQL Wins at LinkedIn!
Employee +0 Vote Up -0Vote Down
I was with a customer last week, who leads technology and operations for one of the world's largest companies. We were talking through his priorities for the upcoming year, and on a page filled with various traditional priorities (consolidation, energy management, disaster recovery, regulatory compliance) were two interesting words.

"Open Source."

I asked what that meant, why it was there. He said they'd done an audit of the firm's development activities, and found an overwhelming number ("hundreds") of open source projects that had been completed behind the scenes, beyond management's oversight. The projects were designed to solve problems deemed too expensive or difficult to solve with proprietary technologies - from meeting a tough budget, to automating a new process. And rather than fight the trend, they

Memcached and MySQL: webminar from a Web 2.0 company

At OSCON, Brian and Dormando gave their ever famous talk, Memcached and MySQL: Everything You Need To Know. I didn’t attend the tutorial, but they assured me it was similar to what was given at the MySQL Conference 2008 (everything, but the very nice buttons dormando was giving out with the memcached logo!). Great, because not only is memcached hot, but I have notes from their talk: Memcached and MySQL tutorial.

Your data and the cloud

I will be speaking on July 29th in New York at an Entrepreneurs Forum on A Free Panel on Cloud Computing. With a number of experts including Hank Williams of KloudShare, Mike Nolet of AppNexus, and Hans Zaunere of New York PHP fame is should be a great event.

The focus of my presentation will be on “Extending existing applications to leverage the cloud” where I will be discussing both the advantages of the cloud, and the complexities and issues that you will encounter such as data management, data consistency, loss of control, security and latency for example.

Using traditional MySQL based applications I’ll be providing an approach that can lead to your application gaining greater power of cloud computing.

How Facebook serves pictures

I caught Facebook - Needle in a Haystack: Efficient Storage of Billions of Photos on Flowgram. First up, I’m not a big fan of Flowgrams - the format is sensible, slide and voice, is excellent, but the delivery in a web browser isn’t optimal… make downloadable videos!

The talk however, was excellent. Do watch it, and learn a bit more about Facebook’s infrastructure. Anyway, some notes I took from the talk:

  • “We’re one of the largest MySQL installations in the world”
  • Use memcache - “We have memcache because databases aren’t fast” (later on in the questions)
  • Separate team focusing on APE (Apache, PHP and Extensions that they work on)
  • 6.5 billion total images, 4-5 sizes stored for each, so 30 billion files, of

Two small PlanetMySQL modifications
Employee +0 Vote Up -0Vote Down

FYI, I changed two parameters on Planet MySQL to accomodate the current flood of postings coming from the MySQL Conference attendees: we now display the last 25 posts (instead of 10) on the front page, the RSS feed now includes the latest 100 posts (instead of 50). This should make sure that posts actually make it to the front page for at least some time, before they fall off again.

Please keep up the good blogging!

 

Services Oriented Architecture with PHP and MySQL

Joe Stump, Lead Architect, Digg. Slides should make its way at Joe’s website soon enough.

Mainly works on the backend, makes sure its scalable, can all the Digg buttons be served, et al.

Application layer is loosely coupled from your data. Whole point of SOA? You can put a service in front of the DB, and move between DB’s if required.

They do use MySQL, but its pretty vanilla.

Old habits die hard
- Data requests are sequential (I need foo, bar, bleh, ecky)
- Data requests are blocking (When you need foo, nothing else is happening)
- Tightly coupled (mysql_query, and if you’re using DB abstraction layer even, you’re still using SQL… you then can’t use CouchDB for instance)
- Scaling is not abstracted (a lot of

Ahead in the Cloud - The power of Infrastructure as a Service
CTO Amazon.com, Dr. Werner Vogels

Pretty much everyone in the audience uses Amazon!

Announced: Persistent Storage for Amazon EC2.

Hitting one page, might actually go to 250 different services, before the page is generated for you. Shows the use of a tool (Amazon internal), that graphs it.

SaaS: Develop -> Test -> Operate

Hardware costs? Software costs? Maintenance? Load balancing? Scaling? Utilisation? Idle machines? Bandwidth management? Server hosting? Storage management? High availability? All this is the differentiated heavy lifting that Amazon bases their services on.

SaaS comes at a very big cost that you have to address.

Memcached and MySQL tutorial
+0 Vote Up -0Vote Down

Memcached by Brian Aker, Alan Kasindorf (dormando). Here are some quick, somewhat sparse notes. Follow the slides, it will help.

Slides: http://download.tangent.org/talks/Memcached%20Study.pdf

Memcached was actually created for LiveJournal. It has evolved a bit over time. Chaos to user based clustering, and then Brad implemented memcached. LiveJournal has about 30GB of cache available between 8-12 machines. The DB reads were down like 10x the moment they started using memcached (its much better now).

Its not only for simple objects (not just a single row)- you can use it for complex queries, and the result can be stored in memcached. Eins.de, Patrick Lenz, is also the freshmeat.net guy. He put memcached on the same machine as the MySQL database server (he has 32-bit machines, and

The Integration of Frameworks
+0 Vote Up -0Vote Down

The irony of it all doesn’t escape me at all. I remember sitting in a small meeting room with my former BioWare colleague Jeff Marvin a couple of years or more ago and we were having a heated debate. The BioWare web site framework was something that we had primarily written in house (many years before) and I was vehemently opposed to moving to an off-the-shelf web framework.

Jeff was arguing quite rightly about some of the many good points about Web Frameworks. I was arguing, quite rightly, some of the many bad points of Frameworks. And so, we came to a stalemate, mostly, and that was that.

Fast forward several years and now working at MySQL (http://www.mysql.com)(now part of Sun Microsystems) I came into a team that had inherited a home-grown site framework, not too dissimilar to the one

I’ve noticed a change of buttons lately on sites where you can bookmark/share the relevant information. So I’ve done a cross sample of A Computer Site - www.dell.com, The MySQL Acquirer - www.sun.com, A News site - www.cnn.com and a technology information site - www.techcrunch.com

What got me to go back and research is I’d never seen a FaceBook icon before, or perhaps I’d never paid enough attention.

At the end most sites now wash out to a site called Add This.

Learning SEO the painful way

Indeed I have a goal of launching a consolidated site of my online presence at ronaldbradford.com at some time soon, and even now I have found I’ve made some SEO 101 mistakes, just in my testing site, and my temporary placeholder.

As a database expert I see plenty of database 101 mistakes with most clients, so part of why my site is going nowhere is I don’t want to make SEO 101 mistakes, especially as I’m not launching a new site, but a migration of existing content to one site.

Telecommuting in 2008

Considering the few posts made recently, regarding Telecommuting, I thought I’d put in my $0.02, adjusted for inflation.
See Cal’s Post and this awesome job opportunity.
I want to discuss the various tools and options available to the telecommuter in 2008.

Disclaimer: I don’t want to make this another post on the benefits of Telecommuting, as I strongly believe there is no silver bullet for the problems an individual or a company faces. There are many drawbacks to telecommuting, and the positives don’t always neutralize the drawbacks.

Background: I’ve been telecommuting since 2003, that’s when I decided to quit working for

Migrating from one RDBMS to another
+0 Vote Up -0Vote Down

Here is some of my thoughts on migrating MySQL to Sql Server. It came out of an email discussion. I’d love to hear your thoughts on migrating to a different database platform, not just MySQL to Sql Server.

I actually thought about writing a white paper or even a course on migrating from MySQL to Sql Server, but never got the time to do it. Sometimes a project doing similar things can serve as a launchpad for this endeavour, but that never came along, at least not yet. I am very interested in database interoperability field though. I’ve done MySQL and Oracle admin in the past and have published some MySQL and Oracle stuff in blogs. I have much better technical skills on Sql Server than any other RDBMS platforms, primarily because I’ve worked on it longer.

Here are some of my thoughts. I think most of it applies equally on migration from
