While you have to provide the paragraphs, ZombieWriter will arrange the paragraphs into different articles for you to use and edit to your heart's content. You may choose between Machine Learning (Latent Semantic Analysis and k-means clustering) or Randomization.
Making decisions is difficult, and I'm very bad at it. This gem is a tool to help decide between any number of options. Returns one or more options out of a provided list of choices. Supports picking entirely at random, or weighting decisions if you're kinda leaning towards one or more options but you're not sure.
LoremIpsum is a jekyll plugin. The plugin can be used as a tag for jekyll. You can get some dummy text for your webpage, without copy & pasting the Lorem Ipsum words yourself. - Use the tag `{% kw_lorem_ipsum 30w %}` to get 30 different words. - Use the tag `{% kw_lorem_ipsum random 4p 7miw 12maw %}` to get 4 paragraphs between 7 and 12 words.
A simple, text-based crowdfunding simulator. Run a group of projects through a series of funding rounds, in which they either receive or lose funds, or are skipped. They also receive a random pledge. Grant projects never lose funds. Match projects have all future funding matched after they reach half-funding. Statistics are printed to the console at the end of the simulation. The normal projects can be specified in a '.csv' file that is given as a command line argument when loading the program, or the default projects can be used. The format for 'csv' entries is Project Name,Goal,Initial_funding with a comma and no spaces between entries and underscores in place of commas within larger numbers (e.g. Your Project,10_000,0). The option is given to save a list of underfunded projects upon exiting the program. The list is saved in 'underfunded.txt' in the top-level folder of the application. Created as a bonus project while completing the Pragmatic Studio Ruby Programming course.
Noisy sensor data, approximations in the equations that describe the system evolution, and external factors that are not accounted for all place limits on how well it is possible to determine the system's state. The Kalman filter deals effectively with the uncertainty due to noisy sensor data and to some extent also with random external factors. The Kalman filter produces an estimate of the state of the system as an average of the system's predicted state and of the new measurement using a weighted average. The purpose of the weights is that values with better (i.e., smaller) estimated uncertainty are "trusted" more. The weights are calculated from the covariance, a measure of the estimated uncertainty of the prediction of the system's state. The result of the weighted average is a new state estimate that lies between the predicted and measured state, and has a better estimated uncertainty than either alone. This process is repeated at every time step, with the new estimate and its covariance informing the prediction used in the following iteration. This means that the Kalman filter works recursively and requires only the last "best guess", rather than the entire history, of a system's state to calculate a new state.
GuerrillaRotate ============== This plugin lets you have multiple view pages for the one action, so that you can rotate through different views in order to test which one is the most effective. This is known as A/B testing, split testing or side-by-side testing. It will automatically switch between the different views for different web requests (uses .rand so is pseudo random, not round-robin or anything). The particular view is sticky for a (rails) session, so that once that view has been chosen for that visitor they will see the same, consistent view each time. It integrates automagically into [Rubaidh::GoogleAnalytics](http://github.com/rubaidh/google_analytics) by setting the override_trackpageview to the name of the unique view file (instead of the action-based URL) so you can track it easily in Google Analytics. Without that you'll want to track it by putting different tracking codes in each of your view templates. Example ------- So, in your views you will create some new templates with something (can be anything including nothing) between the template name and the first part of the extension. So you might have the following files for the products/index action: app/views/products/index.html.erb app/views/products/index_alt.html.erb app/views/products/index_new.html.erb Then all you need to do is tell your controller to rotate for that action: ### app/controllers/products_controller.rb class ProductsController < ApplicationController guerrilla_rotate :index, :show # etc.. end NB: guerrilla_rotate is also aliased as guerilla_rotate for the alternative spelling and typos.

A program to ease and automate the planning of meals. Each meal has a main dish and optionally side dishes as well. These are currently loaded from the meals.csv file in the directory of the command line script. That will be changed in a future release when they will be loaded from a database instead. A menu consists of any number of days that the user chooses. Each day can have any meal as user wishes. When the program is run, the meals are loaded at random from the meal source and presented to the user. The user then has the option to switch out any that she doesn't want on a particular day. If two meals are given, the two meals are switched between each other. If only one meal is given, that meal is switched with another from the meal source that isn't already in the menu. When the user quits the program, the current menu is stored in a menu.txt file so that it can be printed and used in shopping, preparing meals, etc. In a future release, each dish in a meal will be associated with a recipe so that a shopping list and recipe book can be created directly from the same source.
