Copyright-Free Photo Archive: Public Domain Photos and Images The photo archive at Gimp-Savvy.com has more than 27,000 free photos and images saved on our own dedicated server, consisting of over 2.5 Gbytes of data. The goal is to make this archive a resource for collage and photo-montage using digital image editing techniques such as those described in Chapter 7 of Grokking the GIMP. To improve the archive's usefulness, full indexing of the images is planned. In looking through the archive you will be able to browse pages of photo thumbnails, which are linked to the full-size images. The images and photos found in this archive come from three main sources: the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and the U.S. The photos you'll find here are copyright free, but some restrictions still apply. In principle, if an photo is sufficiently modified so that individuals are no longer "recognizable", it should be okay to use.

Memory Note: The way we describe it here, memory for a process is organized on most computers, however it depends on the type of processor architecture. This example is for x86 and roughly applies to Sparc. The principle of exploiting a buffer overflow is to overwrite parts of memory that are not supposed to be overwritten by arbitrary input and making the process execute this code. To see how and where an overflow takes place, let us look at how memory is organized. - Code segment, data in this segment are assembler instructions that the processor executes. - Data segment, space for variables and dynamic buffers - Stack segment, which is used to pass data (arguments) to functions and as a space for variables of functions. 2. memory address code 0x8054321 <main+x> pushl $0x0 0x8054322 call $0x80543a0 <function> 0x8054327 ret 0x8054328 leave ... 0x80543a0 <function> popl %eax 0x80543a1 addl $0x1337,%eax 0x80543a4 ret What happens here? In this case, our return address is 0x8054327. 3.
