ASEBA and Robots - A low cost robot and development environment

This looks to be an excellent prospect.? https://aseba.wikidot.com/en:thymio

[youtube http://www.youtube.com/watch?v=RTi7DjqlGO8?wmode=transparent]

The development environment looks reasonably good and the cost of the Robot itself is around ?85.00 (converted from Swiss Francs). As mentioned in the IEEE article below, for less than ?1000 you could kit a whole class room out with these devices and the software is free.
I am certainly tempted to get one for "my nephew".?

Google Listen APK

I was really annoyed to find out that Google had ditched Google Listen. I had not heard the news so when I formatted my phone and went to redownload it from the Marketplace it has?disappeared (this seems to me the curse of having your software library controlled by someone else, at someone elses whim, your software can just go poof!).?

The Listen app really suited me as a I am big Google Reader user and have all my podcast RSS feeds in there. To manage your Listen subscriptions, all you need to do is drop the feed into a specific folder in your Google Reader account.?

Anyway, XDA Forums to the rescue....

Google Course Builder - Make and consume custom courses

The plan is for people to be able to create their own custom courses. I am not quite sure what the benefit will be over using just a simple wordpress blog and some you tube videos etc.. but we shall see!?

A pocket computer with an Xbox Chatpad and Arduino Uno

This is a brilliant little idea. It reminds of something out of Fallout. I know I already have all the parts to this device. But if he could just make one for me I would be eternally grateful.

Show / Hide Results Pane in SQL Management Studio Query Window Keyboard Shortcut = CTRL+R

A little note to myself as I always forget

To show or hide the results pane when writing queries use CTRL+R.

Not sure why I always forget this. It's probably due to the lack of SQL tasks I have to do these days.?

Computer Laboratory: Baking Pi - Operating Systems Development

Saw this via http://www.engadget.com/2012/09/05/cambridge-university-raspberry-pi-guide/

This looks like a nice introduction into building the basics of an OS as well as writing assembly for the ARM processor.

This is definitely something I am going to look at later this evening. Very exciting!

I am really enjoying all the free materials universities keep putting out there at the moment. It's a real boon for me (who most certainly can not afford to go back to uni after the price hikes).

My current favourite gifs

There's nothing new here. But they are my current faves. 

ECMAScript 5 Properties (Javascript)

I went to the Nottingham Geekup last night. The talk was by @firagabeatsrock. A good talk with some important points to watch out for about Javascript. 

I am blessed with being fairly au fait with Javascript so was familiar with the subject to a fairly in depth level. I made a couple of good notes however. One was to look at the Javascript performannce tool  http://jsperf.com/. As an uber geek I love performance tools. I like nothing more than obsessing over fiendery such as this. 

On the subject of performance, he pointed out that when using a for loop, don't refer directly to the length in the loop as javascript checks it every time. There is more to add to this story however. You can make life even worse by reffering to the length of a jquery collection in a for loop. I believe that is particularly slow and I now have the performance tool above to prove it :-)

The other thing I picked up on was a little reminder to look into the ECMAScript5 stuff. Now I have done a little example of the new properties and how they can have method bodies below...

Ridiculous you say! That can already be achieved! Well, it can to a certain extend but you have very little control over people overriding your object and how you intended it to be used. I was going to go further into this subject but upon looking for supporting information, I found many people had already done a better job of explaining the matter. 

Take a peek at this blog and mind that you follow his update for even more interesting little tips....

Freedom Engine - game changing technology on Vimeo

[vimeo http://www.vimeo.com/48726638 w=500&h=283]

This looks like an interesting project. I'll keep an eye out when this is available to the public http://www.freedom-engine.com/.

I am always dubious about solutions that offer the ability to work across all of the browsers as I have never seen that working well, I am also interested in how they plan on monetising this for themselves (there's no mention of it). But one must remain optimistic!
