The Linux kernel includes full PAE-mode support starting with version 2.3.23, [24] in 1999 enabling access of up to 64 GB of memory on 32-bit machines. A PAE-enabled Linux kernel requires that the CPU also support PAE. The Linux kernel supports PAE as a build option and major distributions provide a PAE kernel either as the default or as an option.
The 32-bit PAE desktop kernel (linux-image-generic-pae) in Ubuntu 9.10 and later, also provides the PAE mode needed for hardware with the NX CPU feature. For systems that lack NX hardware, the 32-bit kernels now provide an approximation of the NX CPU feature via software emulation that can help block many exploits an attacker might run from ...
The term user space (or userland) refers to all code that runs outside the operating system's kernel. [2] User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc.
After navigating a command-line shell to the directory that contains the source code, the following commands are typically executed: [1] ./configure make make install For the Autotools, the configure script logs status and errors to file config.log , and the command ./configure --help outputs command line help information.
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...

The TENEX C shell "introduced file name and command completion in addition to command-line editing features. The tcsh was developed by Ken Greer at Carnegie Mellon University." [21] The shebang, or hashbang symbol was available in tcsh. Also, positional parameters as the argv array including argv[1], the $0 shell variable as argv[0], the Count ...
