Lisp is the second-oldest high-level programming language after Fortran and has changed a great deal since its early days, and a number of dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme. Lisp was invented by John McCarthy in 1958 while he was at the Massachusetts Institute of Technology (MIT). This reference will take y

Assembly language is a low-level programming language for a computer or other programmable device specific to a particular computer architecture in contrast to most high-level programming languages, which are generally portable across multiple systems. Assembly language is converted into executable machine code by a utility program referred to as an assembler like NASM, MASM, etc. Audience This tu

Deleting All Lines with sed We will now understand how to delete all lines with sed. Invoke sed again; but the sed is now supposed to use the editing command delete line, denoted by the single letter d − $ cat /etc/passwd | sed 'd' $ Instead of invoking sed by sending a file to it through a pipe, the sed can be instructed to read the data from a file, as in the following example.

Sessions To save data across multiple requests, you can use either the session or the flash hashes. A flash stores a value (normally text) until the next request, while a session stores data during the complete session. session[:user] = @user flash[:message] = "Data was saved successfully" <%= link_to "login", :action => 'login' unless session[:user] %> <% if flash[:message] %> <div><%= h flash[:m
