PDFs open source optimize
Submitted by MFN under Development , Open Source , a student's life , art on 9/4/2010
Not everyone has an Adobe Acrobat Professional license, much less one has necessarily an operating system running on the Acrobat. So I was looking for a way to optimize PDF files with open source software to shrink the file size so by recalculation of images and compression.
And I also found it. With the combination xpdf and ghostscript to go about it.
I have put together a small script for Windows where you have to adjust only the paths:
set xpdf="X:\Path\to\xpdf"
set ghostscript="X:\Path\to\ghostscript\bin"
set suffix="_opt.pdf"
%xpdf%\pdftops.exe -paper match -level3 hsq.pdf tmp.ps
%ghostscript%\gswin32c.exe -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dColorConversionStrategy=/LeaveColorUnchanged -dBATCH -dNOPAUSE -sOutputFile=hsq.pdf%suffix% tmp.ps
del tmp.ps
The whole course is on Linux / Mac if installed xpdf and ghostscript:
suffix="_opt.pdf"
pdftops -paper match -level3 hsq.pdf tmp.ps
gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dColorConversionStrategy=/LeaveColorUnchanged -dBATCH -dNOPAUSE -sOutputFile=hsq.pdf$suffix tmp.ps
rm tmp.ps
The more current, the respective versions the better the result looks like. If at least my experience.
Are referendums in Germany really make sense?
Submitted by MFN in student's life on 7/22/2010
Last night I looked again at random, the Munich round. The theme was: referendums.
What surprised me was that even the critics had not even noticed the round until the final decisions as unrepresentative of the people were.

Qtoctave 0.9.1 Win32 Fix
Submitted by MFN under General , Development , Student's life , art on 04/05/2010
I found a bug in my windows version. So I patched the source, to fix it.
The problem was, that qtoctave changes it's own cwd when a file is loaded, and then share the directory is not in place anymore.
A fresh build of qtoctave-0.9.1-win32-2 qtoctave-win32-0.9.1-3 should fix these problems.
[Update]
Thx Dan for the report. I forgot a "\ \" + line in 118th octave_connection.cpp I uploaded version 0.9.1-3.
