Work in progress
I’m a slow mover here, far behind the hype-curve, but this blog is currently being moved to jekyll. The following are some notes and links from this process.
Reasons to migrate:
- Cheaper hosting - this blog is currently hosted on DreamHost. By migrating to a static site using Jekyll, cheaper options become available, for example Amazon S3 or Github.

So I just listened to the last IT Conversations podcast of all time All's Well That Ends Well
I'll miss the curation they provided. Did you know that 8 out of 10 interesting facts I quote at dinner parties I learned on the network? ;-)
And still learning: IT Conversations was the 2nd podcast ever? Apparently Doug Kaye uploaded a feed the day after Dave Winer
posted his first example of using the RSS enclosure
I'm not sure the Conversations Network couldn't have remained relevant and valuable for years to come, but it (more...)
Ik kwam vanochtend op Google+ een interessante presentatie van Magaret Leibovic tegen waarin ze onder andere de tools in firefox bespreekt die je kunt gebruiken voor het debuggen van web applicaties op een smartphone.
Safari biedt vergelijkbare tooling om webapplicaties op een iPad of iPhone te debuggen. Deze heb ik (more...)
On my morning commute today I realised that I am actually living in the future. I remember when I got involved in the PythonCard project 10 years ago one of the major questions on the mailing list was why we were building a GUI toolkit when the future was the web. It wasn’t true then but I think that it is now.
Why do I think we have moved now? It is in large part thanks to a book I have started reading called Python for Data Analysis. I have a copy of the book in ePub format and wanted (more...)
It's been a while since I last cranked up mono
to compile some C#
, and this time I'm on a Mac.
Fortunately, no dramas. The mono team have made it a very smooth process. I simply downloaded
and installed the Mono SDK (it is packaged as a standard disk image [.dmg]). That's enough to compile and run simple projects.
$ mcs hello_world.cs
$ mono hello_world.exe
There's a whole cross-platform IDE available now called MonoDevelop
and it looks great if you are doing serious C#. Right now though, I was happy enough to build from the command (more...)
Ruby developers are a pretty spoilt bunch these days. The community has overall done a great job of rolling many of the advances in modern development practice into the tools and conventions we unconsciously put to work every day.
Now I wonder what life is like in the Python community?
Like many Rubyists, I've played around with Python and Jython on and off. But nothing serious. And although you could get into a pedantic syntax war, I suspect for the most part the Python and Ruby communities don't overlap simply because once you dive into one camp, the only real (more...)
This site may not be available for various periods over the next couple of days as I move it lock, stock and barrel to a new web host. It has been a good few years at Cornerhost but it’s time to move. After an exhaustive search I’ve signed up at WebFaction and will be up and running on their servers in no time at all.
This does mean that email reception may be spotty as I migrate. In the rare event that you send me an email and I don’t reply please accept my apologies. Then resend your email. See (more...)
It started with a tweet from Tim O’Reilly. He mentioned a quote that I’m very familiar with – “Data matures like wine, applications like fish”. When I read it I wondered if it was anything to do with. His tweet linked to a blog post called the 11 best data quotes from the DataMarket blog. On that list (which I highly recommend reading) the quote was tentatively attributed to me based on a write up of my 2009 OSDC presentation entitled “Change Bad!”.
I’d like to take the credit for this, I really would. But I can’t. I did (more...)
How many times have you seen a webdev job ad that asks for things like:
Minimum 5 years experience in Ruby on Rails, html5, JQuery, Mongo DB, and building andriod and iphone/ipad apps
So it just came up again on a mailing list, and we all had a good lol.
When people ask for more years experience than the technology has even existed, at one level the incongruity simply tickles our geeky funny bone like a classic joke setup.
At another level however - and one that HR professionals the world over still struggle with - specifying job requirements in (more...)
I am very excited to announce that EclipseLink 2.4.0 is now available for download.
Highlights of this release include:....
Java Persistence units can now be exposed over REST using either JSON or XML media.
Tenant Isolation - Table per tenant
Developers can design and deploy applications where their persistent entities are stored in separate tables per tenant.
This release introduces EclipseLink's NoSQL support for MongoDB and Oracle NoSQL.
EclipseLink MOXy can now be used for the marshaling and unmarshaling of JSON object. This is core infrastructure to the JPA-RS (more...)
on a source code repository and it animates the code's evolution. I think I first saw it used to illustrate the history of Python development since 1990
, and I must admit my first reaction was cool but probably pointless
ran it over our own project, and inspired me to play around a bit with it too.
So after watching our animation a few times I'm sheepishly revising my opinion of gource.
Yes, you probably need to have something invested in the particular code-base to care, and it certainly helps if you avoid the obvious cliche (more...)
I was fired up to try out ember.js
after seeing Cameron's
presentation at the last Singapore Ruby Brigade
I hosted some tests on a Rails 3.2.2 base, and threw in a whole bunch of technologies to see how well they play together. The (more...)
, and maybe tried the jQTouch
framework that these spawned. Meanwhile, the official jQuery mobile framework
has slowly been moving to fruition.
I recently discovered another project - Web 2.0 Touch
- that is pitched as a mini framework with better features (more...)
I have been interested in business intelligence and data warehouse solutions for quite a while. And I have seen that traditional data warehouse and business intelligence tool implementations take quite a long time and cost a lot to set up infrastructure, develop or implement business intelligence software and train users. And many business users are not using business intelligence tools because they are too hard to learn and use.
Therefore some while ago a had an idea of developing easy-to-use business intelligence web application that you could implement and start to use right away and which would focus on ease-of-use (more...)
As of EclipseLink Indigo (2.3.0) you have been able to use the @Multitenant feature
to share a database schema between multiple tenants. Did you know that you can also use this feature together with the Oracle Virtual Private Database (VPD) support that has been available in EclipseLink since version 1.0?
This powerful combination of features allows for the shared tables to be managed directly on the database, and for inserts to be automatically associated with the proper client. Any SQL executed by EclipseLink (even if EclipseLink did not generate it - ie native queries) will go through (more...)
I just released Oracle enhanced adapter version 1.4.0 and here is the summary of main changes.
Rails 3.1 support
Oracle enhanced adapter GitHub version was working with Rails 3.1 betas and release candidate versions already but it was not explicitly stated anywhere that you should use git version with Rails 3.1. Therefore I am releasing new version 1.4.0 which is passing all tests with latest Rails 3.1 release candidate. As I wrote before main changes in ActiveRecord 3.1 are that it using prepared statement cache and using bind variables in many (more...)
GlassFish 3.1.1 shipped today
which makes it the first application server with the new multi-tenancy and extensible persistence unit support as well as all the other new features included in EclipseLink 2.3. If you're a GlassFish developer and you're upgrading to 3.1.1 you can find out all about the new features available in EclipseLink 2.3 on the EclipseLink Wiki
To wet your appetite, Alexis Moussine-Pouchkine posted a screencast
of building a multi-tenant enabled application on a pre-release build of GlassFish 3.1.1 on his blog and now would be a great time to check it out!
Shaun Smith, EclipseLink Team
Since joining the family here at Eclipse a few years ago, one thing I can always count on is a hectic and exciting start to summer. This summer is no exception, and is kicked off with the release of EclipseLink 2.3.0 (Indigo).
Before I continue with brief descriptions of some of the new features of EclipseLink 2.3.0, I would like to thank everyone who was involved with this release. Whether your (more...)
Challenged to take an existing application and re-use it for a new customer or group of users (tenant)? Instead of customizing the application, adding new hardware or re-configuring the database for each new tenant, you can now build EclipseLink JPA enabled applications hosting requests from multiple tenants with all their data co-located.
Starting with EclipseLink 2.3, part of the annual Eclipse Indigo release, you can now have multiple application tenants sharing a database schema. EclipseLink enables you to configure your database tables for shared storage by simply providing tenant discriminator column(s) and providing values for these discriminators within your (more...)
Imagine a system that keeps track of player statistics in a sports league. Personal information such as name, height, weight and basic statistics such as the number of games played is stored for all players.
A persistence unit is deployed with all the mappings described above.
The system admin of a basketball league wants to use the system and add mappings for points scored and fouls. As the system is running they tell EcliseLink about mappings for those fields and the next EntityManager they get uses them.
Starting with EclipseLink 2.3, you can do just that. To do that, (more...)
