A small nokogiri xml reader DSL.
# A small DSL for helping parsing documents using Nokogiri::XML::Reader. The
# XML Reader is a good way to move a cursor through a (large) XML document fast,
# but is not as cumbersome as writing a full SAX document handler. Read about
# it here: http://nokogiri.org/Nokogiri/XML/Reader.html
#
# Just pass the reader in this parser and specificy the nodes that you are interested
# in in a block. You can just parse every node or only look inside certain nodes.
#
# A small example:

Function to create a tcl/tk dialog box for a user to enter variable values.
#' Creates a dialog box using tcl/tk to get input from the user.
#'
#' This function will create a tcl/tk dialog box to get user input. It has been
#' written to be extensible so the R programmer can easily create a dialog with
#' any number of varaibles with custom labels and data conversion of the user
#' entered data. The function will return a list where the element names are
#' \code{vars} and the value is the user input. By default, all entry will be
#' converted using the \code{as.character} function. However, this can easily be
#' altered using the \code{fun} parameter. For example, if integers are required,
#' use \code{fun=c(as.integer, ...)}. It is also possible to write custom

debug SystemStackError in ruby 1.9

This is how I debug SystemStackError when there is no stack trace.

My first attempt was:

begin
  a_method_that_causes_infinite_recursion_in_a_not_obvious_way
rescue SystemStackError
  puts caller
end

Список литературы для ознакомления с concurrent programming и реализацией этих принципов и подходов на ruby. Огромное спасибо @brainopia за составление.

Введение

Начать стоит отсюда. Не пугайтесь то, что это книга по незнакомой OS, эти термины практически везде одинаковые и здесь они изложены в понятной для начинающих форме.

http://www.qnx.com/developers/docs/6.4.1/neutrino/getting_started/s1_procs.html

Прочесть нужно треть главы до подраздела "Starting a process", если С не пугает, читайте полностью. После прочтения вы будете понимать, что такое process, thread, mutex, priorites, semaphores, scheduler, contex-switch, kernel states.
