Good news, I am back in blogging :) In recent years I have spent my time primarily on eazyBI business intelligence application development where I use JRuby, Ruby on Rails, mondrian-olap and many other technologies and libraries and have gathered new experience that I wanted to share with others.
Recently I did eazyBI migration from JRuby 1.6.8 to latest JRuby 1.7.3 version as well as finally migrated from Ruby 1.8 mode to Ruby 1.9 mode. Initial migration was not so difficult and was done in one day (thanks to unit tests which (more...)

(“megaargh!” in pirate-speak) is a Ruby wrapper and command-line client for the Mega API
In the current release (gem version 0.0.3), it has coverage of the basic file/folder operations: connect, get file/folder listings and details, upload and download files. You can use it directly in Ruby with what I hope you'll find is a very sane API, but it also sports a basic command-line mode for simple listing, upload and download tasks.
If you are interested in hacking around with Mega, and prefer to do it (more...)

is the transactional email service by the same folks who do MailChimp, and I've been pretty impressed with it. For SMTP mail delivery it just works great, but where it really shines is inbound mail handling and the range of event triggers you can feed into to your application as webhooks
(for example, to notify on email link clicks or bounces).
The API is very nice to use, but in a Rails application it's best to keep all the crufty details encapsulated and hidden away, right? That's what the mandrill-rails
There are a lot of people who think camera’s in tablets are a bad idea. “Nobody should be allowed to take pictures with a large tablet in front of their face.”
But if you can think outside of the traditional camera box for a moment, and start to think what’s possible if you combine a really portable computer with a decent camera, you’ll soon see interesting new possibilities.
Just a couple examples:

Wow. This year we mark the 20th anniversary of the Visual Basic 3.0
launch way back in 1993.
It's easy to forget the pivotal role it played in revolutionizing how we built software. No matter what you think of Microsoft, one can't deny the impact it had at the time. Along with other products such as PowerBuilder
and Borland Delphi
, we started to see long-promised advances in software development (as pioneered by Smalltalk
) become mainstream reality:
While converting my old wordpress blogposts to markdown i read some of my old
posts. For example, here is what i wrote when Apple launched the iPhone in 2007:
In a couple of years mobile phones will be powerful enough to replace
laptops for most common computing usages. You won’t need a separate laptop.
You walk around with your mobile phone, in the office or at home you put it
in a docking station, attach a keyboard and a bigger display, and you have
all the computing power you need.
Some news this last week indicates we’re getting close (more...)

So eBook sales have surpassed hardcover for the first time
, and it is no surprise that the rise of the tablets is the main driver.
There's something quite comfortable about having a nice digital bundle of information at your fingertips, like warm buttered toast.
With relatively open standards and the ubiquity of ereaders, the ebook has become ideal packaging for all manner of information, from training manuals to open source project documentation. Or even that book that apparently 81% of us believe we have inside.
So how do you (more...)

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...)
I’ve recently written some code to wrangle XML files. Part of the code validates a provided file against an XML Schema stored in a file. When I wrote this code I got tangled up in absolute and relative path manipulations trying to load the XML Schema file. Most of the Python file operations work relative to the current working directory and I needed to be able to load my XML Schema from a file relative to the application root directory. Regardless of where the code was executed from the schema file would always be up and across from the directory (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...)
