Two Minute Timer in mobile.processing

Posted by Nikolaus Gradwohl Sun, 26 Apr 2009 07:50:00 GMT

no system or programming language should be without it's 2 minute timer for all those GTD followers out there. so i made one in mobile.processing.

the programm starts a 120 sec countdown and sends the app in background. After 2 minutes the vibration alarm is activated for 1 second.

i made a qr-barcode that contains the link to the jad file. just point a qrcode reader like zxing to it and install it

you can also use the direct link http://www.local-guru.net/mobileprocessing/twominutetimer/midlet/twominutetimer.jad (but i think it is a bit complicated to enter on a mobile phone)

gimp batchmode script

Posted by Nikolaus Gradwohl Fri, 24 Apr 2009 02:25:00 GMT

for my monstergallery and my pencil drawings i needed a tool that generates the preview icons for me. so i made a gimp script that can be run in batchmode.

The following scheme script defines a function named imagescale which takes a file pattern (like '' or '.png') and a width as paramter. the function iterates over the file list, opens each file fetches the original width and height and calculates the new image height so that the image proportions are preserved. than the image is scaled and saved as a new file by adding "icon-" as a prefix to the filename.

the function can be called in gimp batch mode with the following command

gimp -b '(imagescale "*" 100)' -b '(gimp-quit 0)'

put the script in your ~/.gimp-2.6/scripts folder

(define (imagescale pattern width)
  (let* ((filelist (cadr (file-glob pattern 1))))
    (while (not (null? filelist))
           (let* ((filename (car filelist))
                  (image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
                  (drawable (car (gimp-image-get-active-layer image)))
                  (original-w (car (gimp-image-width image )))
                  (original-h (car (gimp-image-height image )))
                  (height (* original-h ( / width original-w ))) )
             (gimp-image-scale image width height)
             (gimp-file-save RUN-NONINTERACTIVE image drawable 
                (string-append "icon-" filename) (string-append "icon-" filename))
             (gimp-image-delete image))
           (set! filelist (cdr filelist)))))

counting sheep in processing

Posted by Nikolaus Gradwohl Tue, 21 Apr 2009 02:23:00 GMT

Computer are very well suited for boring and repetitive work. I can't imagine anything more repetetive and boring than counting sheep. so i made a processing sketch that does it for me.

click here if you want to let your computer count some sheep for you.

of course the sheep counter is a long int

sispmctl on macos (aka tale of a ikea lamp)

Posted by Nikolaus Gradwohl Sun, 19 Apr 2009 08:32:00 GMT

i just installed a little ikea lamp on my wife's desk. no problem so far, the only thing that's really wierd is that the switch of the lamp is next to the power supply. to use it she would have to crawl under the desk and use the switch :-( - NSF

therefore i installed a sis-pm silvershield from gembird (which has 4 sockets that are switchabel via usb) and sispmctl and wrote a simple applescript program. now she can simply click on the script in the menu to turn the litght on/off :-)

cocoa osc app

Posted by Nikolaus Gradwohl Tue, 14 Apr 2009 03:14:00 GMT

i just wrote a cocoa frontend for my ruby osc sequencer using vvosc.

this is a simple tutorial to show how i got my vvosc app running. i'm neither a xcode nor objective-c expert - so be gentle if there are some mistakes, or there is a simpler more xcody way to do it :-)

processing bubbles

Posted by Nikolaus Gradwohl Mon, 13 Apr 2009 19:44:00 GMT

here comes another completly useless processing sketch by me this time starring bubbles

ok, it's not that useless i changed the transparency of the bubbles according to the speed so slower bubbles seem to be more distant from the viewer than faster ones.

this generates a nice and simple parallax effect.
