Oct 28, 2007 Singapore Listen

Heaven and Hell

Never expected another chance to see Black Sabbath live - let alone in Singapore. But this last weekend, they stormed Fort Canning Park for a huge crowd.

Although the band I saw (Ronnie James Dio, Tony Iommi, Geezer Butler, Vinny Appice) go under the Heaven and Hell name to distinguish from the Ozzy version of the band, this is classic Sabbath. As good or better than a flashback to the Live Evil tour.

I don't think Singapore will see such a brilliant live act for a long time yet. Flawless playing by all, Iommi just magic, Dio as good as ever .. I think they blew the doors of the clubroom at the back of the park.

And the crowd loved it. Any hard rock act that thinks Singapore isn't worth the effort betta check with Dio or Megadeth (who played the night before).

Here's my crap concert photo. I took some video too, but the audio track is useless -the band was pumping out about 100,000 watts too much power for my poor handphone mike!


Thanks to Aat for telling me about the concert and getting the tixs..

16th May 2010 - rumours that Ronnie James Dio succumbed to cancer, but it seems he fights on.

Oct 18, 2007 SOAP Perl

Registering namespaces with SOAP::Lite

About time to post about something ... too many OpEd pieces of late!

An interesting question came up on the soaplite mailing list concerning how to modify the namespaces registered in the SOAP envelope. Documentation is not especially clear on this point.

Of course, a quick hack is to attach a full namespace to an element directly, as in:
SOAP::Data->name('itemName')->attr({'xmlns:mns' => 'http://my.namespace'})

With version SOAP::Lite 0.65 and above, the register_ns serializer method helps to correctly construct the envelope, as shown in the following example:

#!/usr/bin/perl -w
# $Id$
#

use strict;

#SOAP::serializer->register_ns requires 0.65
use SOAP::Lite 0.65 +trace => 'debug';

my $soap = SOAP::Lite
->proxy( 'http://localhost/blah/DummyService' );

my $serializer = $soap->serializer();
$serializer->register_ns( 'http://my.namespace', 'mns' );

my $som = $soap->call(
SOAP::Data
->name('mns:test')
=> SOAP::Data->name('mns:description' => 'an item in my namespace')->type('mns:mytype')
);

This generates the following SOAP request:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:mns="http://my.namespace"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<mns:test>
<mns:description xsi:type="mns:mytype">an item in my namespace</mns:description>
</mns:test>
</soap:Body>
</soap:Envelope>

Oct 18, 2007 OOW Deep thoughts OTN openworld07

A blog about nothing (was: a can of worms)


Jake is right .. this is getting a little too much like Seinfeld.

So many posts about bloggers at OpenWorld.

Seems to me a storm in a teacup (admittedly, roughly the same size as a can of worms, but probably shouldn't be confused - print picture on right for easy reference). Most of it driven by a comparison to what "other" companies do.

As an avid blog reader, I'm actually more interested in an intelligent post from someone who has taken some time to reflect and write about their usage of the software (be it from a project, production or just playing with an OTN download).

Don't get me wrong, I definitely see value in blogging from OpenWorld - as much for the community buzz as discussion of the latest and greatest OpenWorld news. But to put too much emphasis on this I think actually plays into the hands of the supposed PR and Marketing heavies (everything focused around a single, well orchestrated event).

Since I also represent a "global audience" (living in Singapore), there's also the geographic factor. Notwithstanding whether travel costs are reimbursed, I never expect an event centred around a single location in the US to fully represent the diversity of the blogging community I'm so comfortable with.

As such, I'd be even more impressed if we saw OTN podcasts evolve into a more interactive channel (e.g. using talkshoe a la net@nite) to give true, open access for the community to key execs (and then blog about it).

Then there is the question of disclosure. Mary Ann Davidson just posted a poignant discussion of disclosure. Although arrowed at a security audience, the timing is perfect for the opening of Jake's can of worms;-)

I just can't seem to get myself worked up over this either. Perhaps something I drank last night? Or perhaps I've just got a bit more faith in the sophistication of the audience that is now growing up with blogging et al. Two factors: influence (declared or not) stands out like a sore thumb (or else why is it so easy to recognise the executive blogs that are straight out of the marketing playbook). Second, thanks to the magic of RSS I'm not just listening to one person's voice.

So all in all, I reckon getting free registration is a pretty good first step (despite the fact that other companies may do more for you). It's not like the information won't be available for all to see and share after the show, so if you want the prestige of having the first blog post up on a particular subject maybe paying some of your own way ain't such a bad deal.

I would make one concession however: I do think it would be in Oracle and the community's best interest for Oracle to have some flexibility when it comes to the (very) few bloggers who have truely crossed the line and are in fact analyst/press and should thus be treated as such.

So much for my post about nothing;-)

Disclosure: since I work at Oracle, I never expected a blogger invite (and I wasn't able to wangle an employee seat), so perhaps that explains my disinterest in getting all het up about the issue!

The Best Software Writing I

The Best Software Writing I .. it's a pity that there was never a volume II for this classic collection of the best software writing, selected and introduced by Joel Spolsky.

I just picked it up to re-read some of my favourites, like

  • Bruce Eckel's Strong Typing vs. Strong Testing, which is a bit of a milestone article in the rise of the "scripting" languages like ruby and Python.
  • Adam Bosworth's ICSOC04 Talk which reminds us it is more important for computer science to be understandable by people than by computers.

There's also some great pointed humour, with
Definitely one of the all-time-must-have tech reads (and re-reads).
