Charshift is a simple gem which adds functionality to the String class. It's primary function is to act on a given string, taking a fixnum parameter, then shifting each character in that string to a higher or lower ordinal position in that strings encoding. Charshift works with all of Ruby's included encodings and also works with devloper supplied 'custom encodings.' Simply provide an ordered set of characters as an optional parameter and charshift will work on the string using that set instead of the strings native encoding. Charshift also includes a '.get_encoding_length' method which returns the number of of characters which a given strings encoding contains. Finally, strings can be shifted in place using the '.charshift!' method.
A daemon, running in background on a Linux router or firewall, monitoring the state of multiple internet uplinks and changing the routing accordingly. LAN/DMZ internet traffic (outgoing connections) is load balanced between the uplinks using Linux multipath routing. The daemon monitors the state of the uplinks by routinely pinging well known IP addresses (Google public DNS servers, etc.) through each outgoing interface: once an uplink goes down, it is excluded from the multipath routing, when it comes back up, it is included again. An uplink may be assigned to a priority group: lower priority uplinks will only be used if all higher priority ones are down. That's useful to only use pay-per-traffic uplinks if no regular uplink is working. All of the routing changes are notified to the administrator by email. Fault Tolerant Router is well tested and has been used in production for several years, in several sites. See https://github.com/drsound/fault_tolerant_router for full documentation.
BASIC INSTRUCTIONS This gem re-ranks your playlist according to Pink Floyd band members chosen at random. The re-ranked playlist is then exported to your current directory after the program has finished ('quit' to exit). TO RUN DEFAULT CSV SHEET (Some songs from 'The Wall')): songfile TO RUN DARK SIDE OF THE MOON ALBUM SONGS: songfile bin/DSOTM.csv TO RUN A CSV FILE FROM YOUR CURRENT DIRECTORY: songfile your_file_name.csv NOTE: All CSV files must be formatted appropriately with: No header or other text at the top! Column 1: lists all song titles in plain text (The program will appropriately capitalize titles for you.) Column 2: lists integer values for your song ranks (Any negative character "-" will be ignored. If left blank, a default rank of 10,000 is given.) Low rank # means you want the song ranked higher on the playlist. High rank # means you want the song ranked lower on the playlist.
== DESCRIPTION: Charlie is a library for genetic algorithms (GA) and genetic programming (GP). == FEATURES: - Quickly develop GAs by combining several parts (genotype, selection, crossover, mutation) provided by the library. - Sensible defaults are provided with any genotype, so often you only need to define a fitness function. - Easily replace any of the parts by your own code. - Test different strategies in GA, and generate reports comparing them. Example report: http://charlie.rubyforge.org/example_report.html == INSTALL: * sudo gem install charlie == EXAMPLES: This example solves a TSP problem (also quiz #142): N=5 CITIES = (0...N).map{|i| (0...N).map{|j| [i,j] } }.inject{|a,b|a+b} class TSP < PermutationGenotype(CITIES.size) def fitness d=0 (genes + [genes[0]]).each_cons(2){|a,b| a,b=CITIES[a],CITIES[b] d += Math.sqrt( (a[0]-b[0])**2 + (a[1]-b[1])**2 ) } -d # lower distance -> higher fitness. end use EdgeRecombinationCrossover, InversionMutator end Population.new(TSP,20).evolve_on_console(50) This example finds a polynomial which approximates cos(x) class Cos < TreeGenotype([proc{3*rand-1.5},:x], [:-@], [:+,:*,:-]) def fitness -[0,0.33,0.66,1].map{|x| (eval_genes(:x=>x) - Math.cos(x)).abs }.max end use TournamentSelection(4) end Population.new(Cos).evolve_on_console(500)
YPetri is a DSL (domain-specific language) for modelling of dynamical systems. It is biologically inspired, but concerns of biology and chemistry have been purposely separated away from it. YPetri caters solely to the two main concerns of modelling, model specification and simulation, and it excels in the first one. Dynamical systems are described under a Petri net paradigm. YPetri implements a universal Petri net abstraction that integrates discrete/continous, timed/timeless and stoichiometric/nonstoichiometric dichotomies of the extended Petri nets, and allows efficient specification of any kind of dynamical system. Like Petri nets themselves, YPetri was inspired by problems from the domain of chemistry (biochemical pathway modelling), but is not specific to it. Other gems, YChem and YCell are planned to cater to the concerns specific to chemistry and cell biochemistry. A lower-level extension of YPetri is currently under development under the name YNelson. Its usage is practically identical to YPetri, so any YPetri user can now consider using YNelson instead. YNelson covers additional concerns: it allows relations among nodes and parameters to be specified under a zz structure paradigm (developed by Ted Nelson) and it is also aimed towards providing a higher level of abstraction in Petri net specification by providing commands that create more than one Petri net node per command. YPetri documentation is avalable online, but due to formatting issues, you may prefer to generate the documentation on your own by running rdoc in the gem directory. As for the user manuals, there are currently 3 documents applicable for both YPetri and YNelson, whose master copies are stored in the YNelson source directory: 1. Introduction to YNelson and YPetri (hands-on tutorial), 2. Object model of YNelson and YPetri, 3. Introduction to Ruby for YNelson users. These manuals are written to allow beginners, including those unfamiliar with Ruby, to start working with YPetri and/or YNelson. For an example of how YPetri can be used to model complex dynamical systems, see the eukaryotic cell cycle model which I released as "cell_cycle" gem.
