Girl 0.8.0 ("Cinnamon Girl")

The GNOME Internet Radio Locator 0.8.0 ("Cinnamon Girl") release is dedicated to Christmas and the music of Neil Young.


I have been testing various IDS tools and today I came across Tiger.

Tiger is a tool that can be use both as audit and intrusion detection systems. It supports multiple platforms and it is free and provided under the GNU GPL license.

Unlike other tools, Tiger depends only on POSIX tools and is written entirely in shell language.

Valgrind and GNU Emacs lovers

This patch (applied on subversions.gnu.org 2002/07/12) lets you easily debug code line-by-line on x86-linux using Justin Seward's excellent Valgrind memory debugger inside GNU Emacs.

  1. If you run Emacs 21.2, apply the patch to /usr/share/emacs/21.2/lisp/progmodes/compile.el or an optional location.
  2. You probably want to byte-compile it (M-x byte-compile-file RET)
  3. Now M-x compile RET
  4. Either put
    • this after Compile command: in the mini-buffer:
      valgrind -v --leak-check=yes --show-reachable=yes myprog
    • or this inside the source file:

      /*
       * Local variables:
       *  compile-command: "make -k; valgrind -v --leak-check=yes --show-reachable=yes myprog"
       * End:
       */
      
  5. Finally, step forward and back in source files from the *compilation* buffer (of Valgrind error messages), using
    M-n (compilation-next-error) RET and M-p (compilation-previous-error) RET.

Enjoy.

I'm collecting information and samples of proprietary RAW formats from digital still photography devices. Their usage is increasing with the new multi-megapixel cameras.

Simply put, image files in RAW format contain raw data (Bayer array) directly from a CMOS sensor; pure, unprocessed and lossless, opposed to typical JPEGs, where lossy compression is used to reduce file size (and quality).

Unfortunately, there is no universally accepted RAW standard format, so each manufacturer format (even on model basis) differs.

Fortunately, three of the formats are now reverse-engineered.

Support for RAW formats in free software is desirable:

From RAW data, images can be individually customied, different versions of the same image can be created and compared. In addition, any noise in images taken at higher ISO (typically 800 and 1600) can be significantly reduced by saving in RAW format vs. JPEG.

As the CMOS data is stored in a lossless format, no data is thrown away, allthough obfuscated with proprietary compression algorithms. In the case of Canon's RAW formats, they use (until recently secret) proprietary compression algorithm, that reduces the file size greatly. Some RAW formats, like the ones by Nikon in their D1-series cameras, Kodak in their DCS cameras, and Canon in EOS-1D, are disguised as a TIFF, but the data is still proprietary.
