I worte a little skyline generator in processing.

click here to generate your own. Press any key to recreate the skyline if you don't like it

I wrote a processing sketch to show how to access a wms service for showing a map. i use geoserver as a wms provider and the map shown in the screenshots is from http://thematicmapping.org/.

the map can be dragged with the mouse and zoomed with the scroll wheel

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 https://www.local-guru.net/mobileprocessing/twominutetimer/midlet/twominutetimer.jad (but i think it is a bit complicated to enter on a mobile phone)

a while ago i made an abstract art generator in processing. Now i made another one, drawing lines

click here to generate some images.

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)))))

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

I also made another gallery showing some pencil drawings i made.

I just made a gallery of all the monster images i have collected so far. click here to have a look or use the link in the menu. I will add new monsters as i find them

i used the really nice lightbox2 javascript framework for the gallery

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 :-)
