LucID Messenger
Apple (wiki) | Android (wiki) - urs @ 23:03:52

Ever heard of LucID? Just by random run over that messenger, which should enable chatting from iPhone to Android or Blackberry. We managed to chat from Android to iPhone and backwards. But how does one invite people by email? Not a clue yet.

How to OCR multipage PDF files
Open Source (wiki) | Content Management (wiki) - urs @ 16:46:53

The OCR applied here only serves for reasons of indexing PDF files. The page layout will get lost. Nevertheless, the following three steps help you to convert multipage PDF files to a single text file:


 $ convert -density 150 foo.pdf ./tesseract/tmp/p%02d.tif
 $ montage.exe ./tesseract/tmp/*.tif -tile 1x -mode concatenate ./tesseract/tmp/foo.tif
 $ tesseract.exe ./tesseract/tmp/foo.tif output -l eng

For reasons of simplicity the TIF files p00.tif to pXY.tif will get concatenated together to a single TIF file, that has the width of a single page and the height of XY pages. In such a way at least the order of the text or the text flow respectively will be preserved. But one could also concatenate a mosaic of all the TIF files. The density of 150 (dpi) gives reasonable results with tesseract.

Fuppes beliefert MusicPal
Linux (wiki) | Deutsch (wiki) | Music (wiki) - urs @ 20:31:30

Seit Kurzen dringt bei mir die Musik aus der Konserve mittels MusicPal in die Ohren. Die Konserve - eine 2.5 inch, ca. 160GB USB HDD umfasst ein Debian und ein Abbild meiner CD-ROM Sammlung, soweit diese überhaupt schon erfasst ist. Debian läuft in aller Ruhe auf einem Linksys NSLU2. Die Musikdaten werden mittels Fuppes (A free multiplatform UPnP (TM) A/V Media Server) den Endgeräten bereitgestellt. Fuppes war leider (noch?) nicht als ".deb" Datei für die ARM Plattform verfügbar, hat sich aber compilieren lassen. Einziges Sorgenkind ist die 2.5 inch HDD - hier wäre ein RAID oder dergleichen wohl noch ganz vernünftig, allenfalls könnte auch rsync auf eine andere HDD dienlich sein. Die Musik wird über ein BKS Homenet sozusagen frei von WIFI-Strahlung übertragen.

Sharing folders with VirtualBox
Linux (wiki) - urs @ 21:14:14

The host system is a Linux based OS, the guest system - running within VirtualBox - is a Windows based OS. The challange was to share a common folder. The documentation was pretty clear about it; but still it did not work. Now it does. In the guest system, a simple

c:\>net use x: \\vboxsvr\myshare

did the job [1]. There is no need subsitute vboxsvr with 10.0.2.2 or 192.168.0.2 or something like that. myshare is the name of the shared folder located on the host system.
