What’s happening?

Andrew’s arrived home after a productive trip to the United States, and Tech Talk Radio’s executive producer is back at the wheel.

According to our historical archives, Andrew has only missed 5 episodes, out of a total 282.  What an appalling track record.

Actually, I wish mine was that good.

The last two episodes can be downloaded here (Ep 15/2010 – with special guest Anthony Caruana) and here (Ep 16/2010 – with special guest Matthew Robinson).

I’ve listened back to these episodes, and The Panel certainly has a different “feel”. Not sure if it’s for better or worse, but very different.

We’re all looking forward to hearing Andrew’s war stories tomorrow night, though.

More soon.  Over & out.

Woooaah … truckloads.

There are 1001 blog-worthy things to blog in my blog about.

Sadly, time (lusty and blithe) is at his apogee.

In brief, I have:

• Had a shave, since the last blog post;
• Upgraded The Surgery WordPress blog from 2.8.3 to 2.9;
• Moved WordPress blog from Fedora 9 machine with crappy dynamic IP address (it was killing me) to shiny Fedora 11 machine with static IP address;
• Marveled at my ability to upgrade WordPress, SQL databases and move them across Linux machines, AND make grown-up changes to DNS zone files – am surely a guru of such things now and legend in my own lunchbox;
• Undertaken 2 of 8 Tech Talk Radio Summer Series productions, time-consuming but rewarding;
• Upgraded the HTC Dream / Google phone to the next Android operating system, very successful;
• Teetered on the brink of e-mail bankruptcy;
• Ordered a new PC for Christmas;
• Ventured inside an Apple Store for the very first time, and escaped by making only a minor purchase (a new iPod Touch); and
• Just today, assisted Mrs Dr Ron in restoring her iTunes library, after she deleted all the music files from her PC’s hard disk  - successfully achieved restoration by using a third-party app called iRip which we’ve spoken about on Tech Talk in the past (thanks JD, saviour of Dr Ron’s marriage).

I have also Tweeted mercilessly about our well-intentioned (yet incompetent, foolish and mis-informed) Senator for Communications and the Digital Economy, Stephen Conroy.  In case you hadn’t caught up with the news (which the good Senator saved until after the last live episode of Tech Talk for 2009), Australia will be ranked highly with the United Arab Emirates, Iran and China in its foolish deployment of an ISP-based Net Filter.

Adam Turner has had a lot to say about this, and made a clever analogy with a different type of infrastructure.  His blog posts here and here in The Age last week should be mandatory reading.

I’ll blog in more detail about these and other things soon.

I hope you have a great Chrissy and a safe and prosperous New Year.

Last week the Victorian Bushfires Royal Commission released its Interim Report into the tragic events of the 7th of February 2009.

On Tech Talk Radio we discussed the Interim Report with respect to identified technology issues, and technological recommendations which the Royal Commission might make for the 2009–10 bushfire season.

• The Interim Report is publicly available and can be viewed here (link to external site).
• The Panel’s discussion about the Interim Report can be downloaded here (MP3 audio file – 13 minute discussion – file size 12 MB).

On Tech Talk Radio this week we spoke about the current onslaught of “Commonwealth Bank” hoax emails, requesting or “phishing” for account details or personal information.

Source: Commonwealth Bank

Normally I wouldn”t give these schemes the time of day, but the size of this current campaign bombarding our mail servers is enormous.

The ‘real’ Commonwealth Bank site says:

“The Commonwealth Bank does not send emails requesting you to confirm, update or disclose your confidential banking information.”

Well that sounds pretty simple, doesn’t it?

The problem is that unscrupulous spammers are riding the wave of the Commonwealth’s success, registering similar or deceptive domain names and sending hundreds of thousands of spam messages, in an effort to elicit a response from unwary Commonwealth customers.

Messages purporting to be from the following domains have all tried relaying through my mail server in the last 24 hours:

commbiz.commbank.com.au
commonwealths.com
commbank.au.com
bankofthecommonwealth.com
thecommonwealth.org
commbnk.com
commbank.net.au

…and the list goes on.

Fortunately SpamAssassin seems to be knocking them all on the head, by my server at least.

But not all mail servers run real-time anti-spam software, and lots of servers are delivering these messages.

Technology journalist Angus Kidman, writing for APC Magazine, says that the sheer variety of messages means that many anti-spam services are finding it impossible to identify all the problem emails, even if their text sounds familiar and seems easy to detect; also that according to email security vendor MessageLabs (a division of Symantec), in the first week of the campaign more than 22 different core messages were being sent out en masse, with more than 11 variants.

Read the APC article here.

So what can you do to combat the problem?

• Make sure you’re running anti-spam software, and a good email software (like Mozilla Thunderbird, NOT like Microsoft Outlook Express) that detects and quarantines spam;
• DON’T CLICK ON or RESPOND TO spam emails – doing so just verifies to the spammer that your email address is legitimate and active, and invites a thousand-fold increase in spam to your email address;
• Never disclose personal information or credit card details online, unless you’re 100% confident about the security of the website you’re visiting.  Always double-check SSL certificates and the website address in your web browser’s title bar.

If in doubt, don’t click!

Wow.

It’s only taken us six months.

Have a look.

Have you ever watched one of those fancy “webinars” or live video podcasts, and wondered how they broadcast “picture in picture” with different camera angles, or clever switching between cameras, desktop demonstrations and pre-recorded video?

I always thought fancy video switching hardware was required, not to mention some big, big bucks.

But… not so!

I was perusing the Ustream.tv help centre today, and saw a topic which immediately grabbed my eye: “…quickly and easily add scrolling text, logos, RSS feeds, special guests windows, picture in picture, pre-recorded video…”

Woooa, are they serious?  It can’t be that easy, can it?

Yep, it sure is.  Straight away I clicked the link to download WebcamMax for the PC.  This is a nifty utility which gives you significantly more control over your webcam and imaging devices than the default Ustream “broadcast applet”.  My mission was to set-up a “picture in picture” video stream, and it only took a matter of minutes to get this working with WebcamMax.

Setup and installation

Download the 8 MB installer.  Setup is fairly painless and after clicking the “Try” button (you get a 30 day free trial) you’re asked to nominate which applications you want WebcamMax to control video.  I unticked all except UStream.  Then you’re presented with an intuitive GUI which displays any video source that’s currently connected to your PC.  In my case, this was video from a traditional camera, piped through an external USB device like this one.

Next, click on the ‘Sources’ button.  The ‘Main Source’ is your primary video input, and ‘Webcam’ is selected by default.  Look to the right and you’ll see that you can select any other video source simply by clicking the combo box.  Now I’ve also got an in-built webcam in the netbook, which appears as ‘USB video device’.  I switched to that and suddenly I’m looking through the eye of a different camera.  WebcamMax makes it easy to switch between cameras or video sources in this way.

Click the combo to select your main source video device.

You can also click other items in the list, such as:

• ‘Screen’ – live-streams the desktop, by following your mouse pointer or sending the entire screen;
• ‘Movie’ – streams a movie of choice;
• ‘Picture’ – sends a JPG or other image (defaulting to your ‘My Pictures’ folder); and
• ‘Color’ – which lets you set a background colour of any desired shade.

Picture in Picture

But how good is this? Click the button at the bottom of the list control labelled ‘PinP Source 1′.  The same controls appear, duplicated, for a different video source.  Wow!  In no time at all I can display my netbook webcam as a picture inside the main picture.  No expensive video amplifiers or professional switching equipment required!

Picture-in-picture, just like that!

You can get much, much cleverer than this.  Play around with the advanced options and you can move the position of your “picture in picture”, maintain proportions or re-scale, and even have images display as a slide-show.

But wait, there’s more!

I only needed WebcamMax to do “picture in picture”, but it does heaps more than that.  By opening the ‘Effects’ dialogue you can simulate a chroma-key function with different backgrounds.  You can add lighting and shadow effects, grid lines, digital snow, scrolling text… the list goes on.  Select from local or online effects libraries.  There’s even a record feature which lets you write an AVI file to a local disk.

But how does it work with Ustream.tv?

WebcamMax emulates a video device in software.  This means that when you start the Ustream.tv broadcast applet, the WebcamMax “device” will appear in your Video Source drop-down, like this:

The Ustream.tv broadcast applet.  Note the 'Video Source' combo -
just select WebcamMax Capture and you're done.

Simply select WebcamMax as your video device and start broadcasting!

Road test

We’ll put WebcamMax through the hoops over the next few weeks at Tech Talk.  We’ll let you know how it performs, and we’ll listen to your feedback too.  One thing we’re mindful of is not becoming too distracted by the studio webcam; it is, after all, designed to supplement a radio programme, and 99% of our listeners don’t watch the webcam.  We’re hoping to change that, and we hope that using cool utilities like WebcamMax will help us along the way.

A few weeks ago I spoke with Ben May and Mike Beckham on their popular home-grown podcast, The Ploy.

Mike asked me about the National Broadband Network; and the proposed Net Filter and its implications for the future of Australian internet.
