Compress PDF files with ghostscript

This can reduce files to ~15% of their size (2.3M to 345K, in one case) with no obvious degradation of quality.

ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

Other options for PDFSETTINGS:

  • /screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
  • /ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
  • /printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
  • /prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.

Howto install Gitlab on top of opensuse 12.3 32bit

Please read everything before starting!

Install OS

  • Download OpenSUSE 12.3 32bit, Network edition http://download.opensuse.org/distribution/12.3/iso/openSUSE-12.3-NET-i586.iso
  • I chose 32bit, because Ruby Binary Extensions might have problems with lib64 path structure. We workaround this bug.
  • I chose networkinstall, because we need only very few packages and don't need to download everything. only 200MB are downloaded during install
  • the image can easily copied to a usb pen drive using the gui tool "imagewriter" (executed as root)
  • Partition: There are 2 big hard drives. I created on both of them first a primary pratition of 1GB of type LINUX-RAID

Sessions and Conversations in Rails 3

Sessions and Conversations

HTTP is a stateless protocol. Sessions allow us to chain multiple requests together into a conversation between client and server.

Sessions should be an option of last resort. If there's no where else that the data can possibly go to achieve the desired functionality, only then should it be stored in the session. Sessions can be vulnerable to security threats from third parties, malicious users, and can cause scaling problems.

That doesn't mean we can't use sessions, but we should only use them where necessary.
