This won’t be news to those of you in more enlightened locations but I had occasion to contrast the service from the shiny new Sydney Apple store genius bar with my previous Apple repair experiences today and walked away a very happy customer.

My Macbook had not been well since last week. Basically the fan was running constantly which apart from the annoying noise meant that the battery drained in about 30 minutes. Having had my last machine in and out of third party Apple certified repair shops for most of it’s short and inglorious life I was prepared for the worst. I migrated all of my files and data onto a borrowed work laptop and headed to George Street resigned to losing my machine for a couple of weeks.

I walked out half an hour later with a fully working machine. Admittedly the fault was minor and easily fixed but with my last machine each of the repair centres I used had a mandatory (usually two week) period where they kept the machine before looking at it. My experience in George street was about fifteen minutes.

All hail the shiny new store. Now to see if they can fix the internal microphone.

I’ve just upgraded to WordPress 2.6. As I have claims to be a technologist I install and upgrade my blog software using Subversion. An upgrade simply requires issuing an ‘svn switch‘ command and then running the WordPress database upgrade via the page that presents. Usually this works like a charm. Today I had issues.

I’ve logged a support ticket but thought I should mention it here in case anyone else sees the same issue.

When I tried to log in after the database upgrade the login page just kept re-directing back to itself. The main page of this blog was showing, but with an error message stating (in part) – “error in akismet.php on line 487″.

After a little checking around I discovered that Akismet (the WordPress spam fighting plugin) needed to be upgraded at the same time as the core WordPress code and hadn’t. The old version (2.1.4) is not compatible with the latest WordPress release and needed to be upgraded (to 2.1.6). A simple workaround was to download and install the latest version of Akismet by hand so it wasn’t a huge problem, but it would have been nice if the WordPress Subversion repository had been updated to reflect the change.

Update: OK, it’s probably me. A fresh checkout of WordPress (release 2.6 or 2.5) comes complete with the correct version of the Akismet plug in. It must have a problem with my ‘svn switch‘ that I didn’t catch.

I just read, courtesy of Simon, a great article at the Guardian covering a presentation that Adrian Holovaty gave there last week.

Strangely enough I was talking about this with a colleague this very afternoon. My thesis was that data is generated by applications but should be considered independent of them. Treat your data carefully and you have a treasure trove of information that defines your organisation. Take an application centric view of the world and you end up with a load of blobs that are only meaningful in the context of your application code. If you can ever find a way to free your information you can find so many different ways of viewing, interpreting and analysing it.

In essence this is the excitement that surrounds mashups and the value that shown in sites like Chicago Crime and My Society. Expose the data and then marvel at what happens.

As I said in a (remarkably brief) presentation that I gave tonight – I’m Andy and I’m a data manager. If I can ever find a way of making a living taking data, turning it into information and making it available in new and interesting ways I guarantee that I will quit my day job in a heartbeat.

I’m sure I read this somewhere recently, but my scratchy memory and command of Google can’t bring it back to me.

Is there a Python idiom for accepting either a file name or a file object as a function parameter?

The closest I can get is this;

def my_function(file_name_or_object):
    try:
        open(file_name_or_object)
    except TypeError:
        file = file_name_or_object
    return file

Any improvements on this are more than welcome.

As the feedback I got on the daily twitter posts was entirely negative they are gone. Sorry for that folks.

It seems that I’ll have to write more original content instead, I will see what I can do.
