The Australian company Nearmaps today released high resolution aerial photos of the Brisbane floods. The images were taken from two Cesna aircraft at the height of the flooding last Thursday, and were specially commissioned by the Qld state government and Brisbane council.

The SMH reports that the CEO of Nearmap, Simon Crowther, commented that “It’s super high resolution and you can zoom in and see a walnut on the ground without it pixelating.” I’m not sure why you would want to look at a walnut, but I see what he means.

As the News tonight details the heroic clean-up efforts, it is sobering to see the extent of the flooding.

Have you ever had an urgent need for swim goggles to find something underwater, but none were available?

No? Well, neither have I. But if I ever do, the technique that Will taught me today will come in handy.

You can see clearly underwater by creating a ‘mask’ with your hands, and using it to trap bubbles of air.

This video by Will and Millie explains all

We went for a walk along Surfer’s Paradise beach this morning, thinking we would come across some flotsam or jetsam after the awful Brisbane floods (dead cows or dead couches?). However, all we found on the sand was our old friend, the bluebottle. 

There were lots of people swimming nonetheless, which reminded me that I should check what is the best evidence on  first aid for a bluebottle sting – sand, vinegar, cold water, hot water, cream?

The answer is hot water.

The Medical Journal of Australia published a paper in 2006 which demonstrated that hot water immersion at 45 degrees produced a 87% reduction in pain, compared with 33% of those treated with ice.

Therapeutic Guidelines (tg.org.au) recommends – 

– wash the sting site with sea water
– remove any tentacles
– hot water immersion at 45 degrees for 20 minutes, or a hot shower
– no vinegar

The Resuscitation Council has a paper on jellyfish envenomation at

http://www.resus.org.au/policy/guidelines/section_9/guideline-9-4-5july10.pdf

To complicate things, Although vinegar makes bluebottle stings worse, it can decrease the nermatocyst discharge from the potentially lethal Box Jellyfish and (probably) jellyfish that cause the Irukandji syndrome, and so the application of vinegar for 30 seconds is considered good first aid practice in tropical Australia.

So, hot water is best for Bluebottles. If there is a possibility that a tropical jellyfish caused the sting, then use Vinegar.

Best of all – don’t swim when there are jellyfish about.

Today I learnt that Ronnie Corbett is still doing his thang. Who would have guessed?

I also learnt that Apple owners have bigger dongles.

Thanks to both Mukesh and Donna for forwarding this to me.

Presentation Zen
6a00d83451b64669e200e552517715
Garr Reynolds is the acknowledged master in the world of presentation design and delivery.

Garr is the Professor on Management at Kansai Gaidai University in Japan, and the author of the book, Presentation Zen, which is based on his blog of the same name. He writes about how one can best connect with an audience, and deliver a message that sticks.

He has recently released his third book, ‘The Naked Presenter: Delivering Powerful Presentations With or Without Slides’. I downloaded this on my Kindle for iPad today, and am looking forward to reading it. (Although the design of the original Presentation Zen book is beautiful – it is a pity not to get it in hardcopy)

In 2008 Garr delivered a talk to the Google staff which summarised many of his principles, and you can view this in full here

His key points :
Preparation – 
Three words to keep in mind – Simplicity, clarity, brevity.
‘Start with the Beginner’s Mind’ by  looking at things from the point of view of your audience. 
‘Plan Analog’ – plan your talk away from your computer, on paper.
What is your absolutely central point? Why does it matter.
“If the audience could remember only one thing (and you’ll be lucky if they do), what do you want it to be?”
Remember that you are crafting a story – Keep things simple, using examples and stories. A presentation is never just about the facts.

Design
People cannot read a slide and listen to you at the same time. 
If your slides consist of bullet points with everything you are going to say, people will not listen to you. (they can read faster than you can speak).
The purpose of a slide is to enhance, but not replicate, your narrative. If used, slides should consist of strong visual images.
Presenters too often use their slides for two functions that are better fulfilled by other means – they use them as speakers notes, and to be handouts or lecture notes. (”I know you can’t read this slide, but…..“)It is better to have written notes to prompt you to remember the flow of your talk, and to prepare separate handouts containing detailed information that you want people to know, (or provide a web link). 

Delivery
Be completely present – Presentation requires your full presence at that time and place.
You need solid content and logical structure, but you also have to make a connection with the audience.
We all end up sitting through a lot of long talks, (at least with smart phones we can check our emails) As Guy Kawasaki writes in the forward  to Presentation Zen, we all want to see presentations that are short, simple, legible and engaging. I think it would be good if more people were exposed to the ideas of Garr Reynolds.
