Project Xense & Random Doodle
At the Entertainment Technology Center they allow us to borrow Wacom Tablets, so I got myself a Wacom Intuos 4 Extra Large. Yes, EXTRA LARGE!!! It's 462mm x 304.8mm (18.2" x 12.0") with 8 express keys, a touch ring and a pen with Advanced Pen Tip Sensor.
Anyway, working hard on Project Xense to create 3 interactive exhibitions for the National Museum of Health and Medicine in Washington DC about retinal implants, cochlear implants and neuroprosthetics.
Here's random wacom doodle of a girl with a prosthetic arm...
[Fix] Joomla: Parameter 1 to modMainMenuHelper
Warning: Parameter 1 to modMainMenuHelper::buildXML() expected to be a reference
At present Joomla! is not certified to work with PHP 5.3.0. If you see this error message on your Joomla website, probably your web host is running PHP 5.3 or recently upgraded to PHP 5.3 (which was my case).
To fix this, go in the helper.php file (/modules/mod_mainmenu/helper.php) and change
function buildXML(&$params)
to
function buildXML($params)
Now the error should be gone!
Chrome's New Tab Button UI
Have you noticed the small change in the Chrome UI? The "+" is gone in the "New Tab"-button! It's been bugging the shit out of me since I saw it a few days ago. Something doesn't feel right without the "+" :(
[How] Flash: Seek() & PlayHeadTime() Accuracy
Using seek() and PlayHeadTime() with FLVPlayback component of video files in Flash can be quite inaccurate. We had the same problem when we were building a prototype for our project, which involved switching and syncing of videos using specific timing. PlayHeadTime gave a decimal value, but whenever we would do a seek() using the PlayHeadTime value on a video, the timing would be off by 0.5-1 second.
Apparently, the accuracy of the seek() function is dependent on the keyFrameInterval of the video and the FPS meaning Precision = keyFrameInterval / FPS.
So for example, if you have a keyFrameInterval = 30 (1st frame will be a keyframe, 30th frame will be a keyframe, 60th frame ... etc.) and FPS is set on 15, you'll only be able to seek in 2-seconds intervals of time (precision = 30 / 15).
To make the seeking more accurate, set the key frame distance when exporting your video with Adobe Premiere. This option can be found in the "video" tab, "Advanced Settings", check "Set Key Frame Distance" and set the key frame distance lower. Export it and now your seek() accuracy would be more precise!
