Assign a keycode event to the specified keyboard scancode. Te kernel mathes these to it's own keycodes.Scancodes in the range of 1-88 are hardwired in the kernel,but the remaining scancodes can be assigned to keycodes in the range of 1-127. Use getkeycodes to see current assignment. Use showkey to discover what scancode a key is sending.If you want to quit from the getkeycodes command, just wait for a short time and it may offer the commandline.
setleds. setleds[options]
Display or change the LED flag settings (Num Lock, Caps Lock, and Scroll Lock) for the current virtual terminal.WIth no options,display the current settings for all the three flags. Can be used in a startup script to set the initial state of the LEDs.

multiprocessor.
$cat /proc/1119/cpuset / $
lightweight objects in the linux kernel that enable users to partition their multiprocessor machine.
Knowledge
Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system
source : http://en.wikipedia.org/wiki/Multiprocessing
Compiler
GNU Make -j [jobs], --jobs[=jobs]
Specifies the number of jobs (commands) to run simultaneously. If there is more than one -j option, the last one is effective. If the -j option is given without an argument, make will not limit the number of jobs that can run simultaneously.
computer networks
machines with multiple processors can attach network programs of higher priorities to a processor that is little consumed or idle.

full size packets . tcp_retrans_collapse
$cat /proc/sys/net/ipv4/tcp_retrans_collapse 1 $
Try to send full-sized packets during retransmit. This is enabled by default.
TCP smart Framing, or TCP-SF for short, enables the Fast Retransmit/Recovery algorithms even when the congestion window is small. Without modifying the TCP congestion control based on the additive-increase/multiplicative-decrease paradigm, TCP-SF adopts a novel segmentation algorithm: while Classic TCP always tries to send full-sized segments, a TCP-SF source adopts a more flexible s segmentation algorithm to try and always have a number of in flight s segments larger than 3 so as to enable Fast Recovery. We motivate this choice by real traffic c measurements, which indicate that today's traffic is is populated by short-li flows, whose only means to recover from a packet loss is by triggering a Retransmission Timeout. The key idea of TCP-SF can be imple- mented on top of any TCP flavor, , from Tahoe to SACK, and re- quires modifications s to the server TCP stack only, and can be easily coupled with recent TCP enhancements. The performance of the proposed TCP modification were studied by means of simulations, live measurements and an ana- lytical model. In addition, the analytical model we have devised has a general scope, making it a valid tool for TCP performance evaluation in the small window region. Improvements are remark- able under several buffer management schemes, and maximized by byte-oriented schemes.
