More motivational posters
Made a few more posters out of funny things I've found or taken photos of. You might notice I have a weird sense of humor. Why thank you for noticing.. hehe. I think my humor stems from too many episodes of Family guy and Simpsons. Some of these posters are up on Very Demotivational posters already. The Candy gone wrong one is already on the front page. Sweet.

Fuck yeah!
Awesome times for RTRT!!! 2010 is definitely going to be a breakthrough year for GPU based raytracing. There's a sudden tsunami of GPU renderers coming from everywhere. It started with the announcement of V-Ray RT for CUDA by Chaos Group at Siggraph 2009, and was followed by the iray demonstration by mental images at Nvidia's GTC 2009. Then in December, LuxRender showed their experiments with an OpenCL accelerated version of their renderer. This month, a new renderer popped up, called Octane Render, which is being developed by the former lead developer of LuxRender. As a reaction to this newbie unbiased renderer, other render companies decided to unveil their GPU acceleration plans as well: Fryrender (Arion), Bunkspeed, Indigo Renderer. I'm sure Maxwell Render and Kerkythea (or Thea Render) will follow very soon.
I think that most render companies were impatiently waiting for Larrabee, because the idea of porting their render software to a many-core CPU/GPU hybrid sounds much more attractive than porting to the relatively inefficient and memory starved GPU architecture... at least that's what most programmers without GPGPU experience would think, and they needed proof (in the form of OptiX (NVIRT), V-Ray GPU, iray or even the raytraced Ruby demo by OTOY) to realize that GPUs were in fact incredibly fast at certain ray tracing algorithms such as ray casting and path tracing. When Intel announced in December that Larrabee was not going to see the light of day for at least another two years, these companies had the choice: remain competitive by incorporating GPU acceleration into their product as soon as possible, or stagnate as a CPU-only render company and loose marketshare to their GPU embracing competitors.
In short, my dream of realtime photorealistic graphics at playable framerates has come a huge step closer to reality. Realtime raytracing is not an academic PhD project any longer, but it has become big business, now that the big guys in hard- and software are playing with it. I'm sure that this trend of GPU accelerated final production rendering (not just for previz purposes) will spill over to Hollywood CG companies. I'm incredibly excited at this revolution and I'm eager to see what's going to happen next (GPU cloud ray tracing like RealityServer, Fusion Render Cloud???)

Knowledge is No Longer Power, Collaboration Is
Last year I had a few embarrassing moments where I was accessing the latest contemporary eLearning publications and sharing these with colleagues well before Head Office was informed by conventional routes. Fortunately our structure is relatively flat and very collaborative, particularly amongst the eLearning Team. The Head of eLearning asked me how did I get all of this information somewhat instantaneously, did I have the best RSS feeds around? My one word answer was Twitter (twitter.com/simoncrook).
By ‘following’ some key people I have found myself informed of the latest publications, resources and thinking around eLearning. Thanks to Education.au (@educationau) I found the SICTAS ‘Annual Report on Emerging Technologies’ immediately. Thanks to Allison Miller (@theother66) I came across ‘2010 Horizon Report Preview’ in 2009! Only the other day Andrew Churches (@achurches) informed his network of the Becta report ‘The impact of digital technology’. All of these publications are extremely useful, particularly when happened upon almost immediately. By following Tom Barrett (@tombarrett) I am privy to his excellent, collaborative, online presentations in Google Docs on various eLearning applications e.g. ‘Twenty-Nine Interesting Ways to use Twitter in the Classroom’. All of these resources empower me in my job as eLearning Adviser and as a lifelong learner. I can subsequently inform my network of teachers, schools and advisers of such information, thus empowering them.
As Matt Wells (@mbw_61) informed me, a student can now download the whole of Wikipedia onto an iPhone. This means students can have immediate access to far more information than any teacher holds in their head. Accordingly, the balance of power in the classroom has changed if it is only about knowledge and recall. (Fortunately we are evolving teaching practices to push higher order skills than ‘remembering’ such as ‘creating’ (see Blooms Digital Taxonomy)). Rather than being a vessel of knowledge, teachers (and students) can attain true power by collaborating with a wide variety of people. The easiest way to collaborate these days is through Web 2.0 applications and social media such as Twitter, Google Docs and Nings. Rather than simply ‘knowing’ their subject, a teacher can now find various ways of exploring it using contemporary media or keep themselves informed of the latest classroom activities or better still, share their work with the world.
People no longer have to wait for the traditional powerbrokers (teacher, employer etc.) to disseminate what limited information they discern as appropriate for the consumer. By collaborating with each other online, anyone can find out anything, anytime, anywhere.

Arion Render, a hybrid GPU/CPU unbiased renderer
Amazing and extremely fast GPU/CPU raytracing from the maker of Fryrender:
Videos and info here http://www.randomcontrol.com/arion
The nice thing is that it's also a production renderer, just like Octane Render. There's no seperate render core for preview and final rendering, they are one and the same!
The race for realtime "production" rendering is definitely on...

Helpful or stupid?
Yes that's my son's bum. Yes that's where Pooh comes from. I'm quite glad Disney put that on there.. I was starting to think poo was just a magical thing kids did :D uploading to Very Demotivational posters now. These jeans were just a little bit of fail..

Reinventing the Wheel is No Bad Thing … it is a Necessity
Towards the end of last year a couple of teachers from different schools approached me asking when ‘we’ (the System) were going to create or compile a complete set of Powerpoints or SMART Notebook files so they could teach their respective subjects. Their reasoning was that there was no point in them ‘wasting time’ and reinventing the wheel.
I have a few issues with this request:
• Since when has the preparation of lesson materials not been the responsibility of the classroom teacher?
• What pride or depth of knowledge in such resources would these teachers have to best engage the students?
• Does one size fit all suddenly?
• If all we had to do was flick through the slides of a presentation, why bother having a teacher at all?
• This is awful pedagogy! Going through someone else’s material slide by slide for any length of time is not teaching. Unfortunately however, this is still a regular practice amongst some teachers just as going from one page to the next in the textbook.
Hiding my irritation, I pointed out to one teacher that if he simply wanted a Powerpoint on any subject matter all he had to do was an Advanced Google Search, selecting ‘ppt’ as the file type.
For example there are 54,200 ppts on Nutrition alone.
However, I suggested that he could not rely on the quality of these resources and would have to spend time discerning their relevance. I also pointed out that this was very teacher-centred and considering that every student now has a laptop (thanks to the Australian Government’s Digital Education Revolution http://www.deewr.gov.au/SCHOOLING/DIGITALEDUCATIONREVOLUTION/Pages/default.aspx) wouldn’t he rather engage his students in something more student-centred where they could take ownership of the work they produced.
For me, ‘ownership’ is the key. We know this works with students, that they take pride in their work when it is their own creation. This is also the case with teachers. If we create a resource we will have done so knowing the individual needs of the students, the context in the curriculum and how it will fit into the overall lesson plan. Every year our classes are different plus we all teach with an individual style. Therefore reinventing the wheel is no bad thing … it is a necessity. We should continually adapt and evolve our resources and those created and shared by colleagues.
As a Physics teacher I was lucky enough to borrow some wonderful resources (Powerpoints ironically) created by Greg Pitt of Hurlstone Agricultural College. They were ‘definitive’ and literally addressed every dot point in the syllabus. However, if I was simply to go through every slide with my own class they would not come close to achieving the results that Greg’s class did and would be bored witless. What I had to do was take the real gem aspects and integrate them into my own teaching. By reviewing the materials at my fingertips I was able to customise the experience to my students and exhibit a depth of knowledge that the students would value, responding to my sincerity and belief. No teacher can (should) stand tall and look a student and their parents in the eye if all they have done through the course is flick through the same old material that they and their colleagues have been doing so for years. I know for a fact that Greg adapted his own resources regularly and integrated them all within some excellent practical activities, hence his outstanding results.
A common scenario that excuses many teachers (in their eyes) to not take ownership of their delivery is when they find themselves teaching a subject for the first time. However, it is not good enough to say a subject is not one’s specialism or it’s not the class one signed up for. In this situation more than ever a teacher has to prepare their own materials so as to pre-empt the problems the students will raise and deepen their own understanding. This is where collaboration comes in. Functioning as part of a Professional Learning Community and sharing resources means that teachers can mutually support each other. It does not mean that one teacher or Coordinator (or System) makes all of the resources and everyone else dispenses them without ownership, responsibility or accountability.
Interestingly, another System (the largest in the State), has gone to great lengths and prepared resources for every point on the syllabus such that their teachers will be able to have their students use their laptops (or netbooks in this case) provided by the Government in the classroom. I would suggest that conscientious teachers will adapt these with their own work but many will take no ownership and simply issue the worksheets and instructions as they are.
As a postscript, in a year when we achieved our best ever results, the teacher who asked about the Powerpoints has just received the worst exam results in his school. I would suggest that this is not because he lacked a full set of slideshows.

Octane Render: a realtime GPU based unbiased renderer
The flood of realtime GPU path tracers and renderers keeps continuing and Octane Render is the latest newcomer. It's made by Terrence Vergauwen, a Belgian and compatriot of mine :-), who was the former lead of LuxRender. It's incredibly fast (currently CUDA only): www.refractivesoftware.com
Be sure to check out the video. It might not be as impressive as the iray video, but that was runnning on 15 Tesla GPU's, while the Octane video was recorded with 1 GTX 260!
The ever growing list of GPU renderers:
1 V-Ray RT GPU
2 iray (mental images)
3 LuxRender OpenCL (smallLuxGPU, David Bucciarelli)
4 Octane Render (Refractive Software)
5 BrazilRT (Caustic Graphics)
6 FryRender, Maxwell ????

Server Migration and Maintenance
For those who are keeping score, the Andromeda Underground forums are in the process of maintenance, upgrades and server migrations. What started as our upgrade to vBulletin 4.0 has now been incorporated to a full server migration and update. As a result of these sweeping upgrades and changes, the forums will be pretty buggy as we work out glitches and update our plugins to the latest versions to restore our original functionality for vBulletin 4.0. As a result, expect that the forums will be sporadically taken offline for lengths of time as we continue performing maintenance and upgrades in line with these changes.
Along with this major upgrade, we have been migrating the system to a more capable server system as well, so please bare with us as we make these changes and upgrades going forward. The andromedaunderground.com domain still works, but for the time being is redirecting to the secondary TLD in order to alleviate prior compatibility issues which were found on January 7th, 2010. Database migration seems to be completed and all user accounts remain intact, though crisis was narrowly averted which would have left us starting from scratch, thanks to the help of our own COO Damon "Cybernome" Miles.
The Legacy theme for Andromeda Underground has been disabled as a result of the vBulletin 4.0 upgrade due to compatibility issues, and we are currently in the process of customizing the theme for the new forums over a long term process in order to closely approximate what we originally had in the 3.8 version.
Some plugins are currently on hold while we await proper updated versions, so again please be patient as we restore functionality as quickly as we can.
For members who are using a bookmarked address, please be advised that the raw address previously used is no longer valid due to the server migration and will return a 404 error as of January 8th 2010. The new address you should be using (and should have been using instead of the raw address) is http://www.andromedaunderground.com in order to properly redirect and keep your links up to date. As always, we highly advise our members to use only the andromedaunderground.com address to access the forums instead of bookmarking the raw domains that it may point to.
As of February 1st 2010, we will begin experimenting with Google Adsense in order to partially alleviate the rising costs of running the Andromeda Underground system. Our statistics are showing that we are receiving a large number of visitors per day who are not registered users of our forums, and as such our bandwidth is soaring.
Remember, the Andromeda Underground is a private system by invitation only and is an excellent resource for expert analysis and brainstorming for new technologies and projects related to the Andromeda Media Group team. Contained therein are a vast library of documentation, whitepapers, research, and source code which overall are not always available to the public. in order to remain a private venture, we must look for manners by which to continue to keep our operating costs under control. We ask for your understanding concerning the implementation of Google Adsense on February 1st 2010, and ask that you remain within the Terms of Service as outlined within the forums publicly (in the event that donations are not ample to cover cost of operation Andromeda Underground reserves the right to display advertising).
Within the SecondLife platform, an official Andromeda Media group has been formed with appropriate tags for all of our private members. If you are a member of Andromeda Media Group and also use SecondLife, please contact Aeonix Aeon in world to establish your group membership and official tag.
We would like to acknowledge and thank our benefactors for their contributions, and we would also like to take this time to wish everyone a Happy New Year as well, in the hopes that our group will see strides in progress with the various Andromeda Labs projects currently underway.
To this end, thank you all for your participation and continued interest in Andromeda Media Group! We look forward to a productive and fruitful 2010!
Sincerely,

Picnik and Jing
I was recently using Jing for screen capture (still and video). However, the latest update requires the Administrator to install it - I still don't have full Admin rights on my laptop, ridiculous I know! Fortunately I read a tweet from Judy O'Connell @heyjudeonline about the Picnik Add-on for Firefox. Now all I have to do is right-click and and a screen shot is taken by Picnik which can then be edited within Picnik. Too Easy! I love the fact that this processing is done in the 'cloud' and I don't have to download and install any software (that being said, Jing is very good, particularly for capturing video of what takes place on screen).

Prezi
My first attempt at Prezi. I'm using it for a workshop on Google Docs. Both Prezi and Google Docs rock!
New Year's Resolution
Ok, I'm not used to making New Year's Resolutions but this year I am going to try and maintain this blog as a means of recording and sharing any great eLearning ideas and resources I come across. I will also continue to maintain my microblogging on Twitter - twitter.com/simoncrook and social bookmarking on Delicious - delicious.com/EvertonPom
Here's to a great and collaborative 2010!
