Reducing PDF file size

I just needed to reduce a PDF file size (because it had several high res images on it), and found these two solutions:

http://askubuntu.com/questions/113544/how-to-reduce-pdf-filesize http://www.alfredklomp.com/programming/shrinkpdf/

The last solution, a shell script worked nicely and reduced my PDF file size from 20MB to 2MB!!!

Here’s the script that I copied from the site above:

#!/bin/sh

gs -q -dNOPAUSE -dBATCH -dSAFER \
-sDEVICE=pdfwrite \
-dCompatibilityLevel=1.3 \
-dPDFSETTINGS=/screen \
-dEmbedAllFonts=true \
-dSubsetFonts=true \
-dColorImageDownsampleType=/Bicubic \
-dColorImageResolution=72 \
-dGrayImageDownsampleType=/Bicubic \
-dGrayImageResolution=72 \
-dMonoImageDownsampleType=/Bicubic \
-dMonoImageResolution=72 \
-sOutputFile=out.pdf \
$1

N-Bot goes to Berkeley!

N-Bot, the 10-dollar robot that we developed here at the NatalNet laboratory (UFRN-Brazil) is currently on display on the UC Citris Tech museum at University of California, Berkeley.

The exposition will be held until March 1st and is open to the public.

Attached to this post there is a PDF file of the museum brochure designed by Dan Chapman.

Thank you Prof. Ken Goldberg for such an honorable invitation to show our work.

Brazilian trains years ago

I always loved trains. No wonder why: when I was a young kid I used to frequently ride trains with my grandmother Angelina. She had a free pass for any train because my grandfather worked at the railroad company (Fepasa). These are photos of my great-grandfather, Egydio Vidal, who came from Italy and was an engine driver for Fepasa, the São Paulo State railroad company. I miss those rides.
