If you have special libraries or foreign function interfaces, please do likewise (preferably including the information below ). You can then send the data between different threads, and it will not get corrupted. Functional programming has been becoming more popular over the last few years. Indeed, many of the most important ideas in modern languages have their roots in functional programming. A few weeks ago I started a series of posts on various things you could do with a functional fold.

Generally, an event queue is provided as a part of any event-based system, and the major event-based systems in Java are no exception. An event queue serves as an intermediary between event producers and event handlers. The role of the event queue is to serve as a drop-off place for events that need to be handled, sort-of like a To Do list Beginning Scala (Expert's Voice in Open Source) online. This makes pure functions easily testable and less bug prone. Obviously, not all abstractions can be directly implemented with pure functions. For example, think about input/output operations, logging, DB reading and writing, etc. In functional programming there are models and abstractions that allow us to deal with these impure abstractions in a pure way, which results in cleaner and more composable code Functional Programming, download online Functional Programming, Glasgow 1990: Proceedings of the 1990 Glasgow Workshop on Functional Programming 13-15 August 1990, Ullapool, Scotland (Workshops in Computing) pdf, azw (kindle), epub.

For example, 2D coordinates could be stored as an array [2,3] or object {x: 2, y: 3}. // Providing functions to convert in both directions makes them isomorphic. const pairToCoords = (pair) => ({x: pair[0], y: pair[1]}) const coordsToPair = (coords) => [coords.x, coords.y] coordsToPair(pairToCoords([1, 2])) // [1, 2] pairToCoords(coordsToPair({x: 1, y: 2})) // {x: 1, y: 2} An object that has an equals function which can be used to compare other objects of the same type , source: Implementation of Functional download for free Implementation of Functional Languages: 15th International Workshop, IFL 2003, Edinburgh, UK, September 8-11, 2003.

In Chapter 14, Test-First Programming, you stepped through the implementation of basic unit tests in Python. In Chapter 15, Refactoring, you saw how unit testing makes large-scale refactoring easier. This chapter will build on those sample programs, but here we will focus more on advanced Python-specific techniques, rather than on unit testing itself download Beginning Scala (Expert's Voice in Open Source) pdf.

Building Web, Cloud, and Mobile Solutions with F#

If you'd have a imperative background, functional programs will look like a crypt language. Not because it's actually crypt, but because you still don't know its common idioms. Once you master its fundamentals, it gets a lot more readable. Check out this following program, written in both Haskell and JavaScript (using Imperative style): It's a very simple program , source: Metaprogramming Elixir: Write read for free Metaprogramming Elixir: Write Less Code, Get More Done (and Have Fun!) online. There are different ways of solving problems other than object-oriented programming. You may already know how to solve a problem with OOP, but now Swift makes it very easy and convenient to use functional programming download Beginning Scala (Expert's Voice in Open Source) pdf, azw (kindle), epub, doc, mobi. So why does “Why Functional Programming Matters” matter again? The great insight is that better programs separate concerns. They are factored more purely, and the factors are naturally along the lines of responsibility (rather than in Jenga piles of abstract virtual base mixin module class proto_ extends private implements) Logical Foundations of Functional Programming (Ut Year of Programming Series) download online Logical Foundations of Functional Programming (Ut Year of Programming Series) online. Someone who’s raised on conventional Java alone is likely to be confused (cache miss? page fault? skip a gear?) by a loop in Java which is coded using recursion. Not saying they won’t work it out eventually, but it takes extra effort. What are the initial and stopping conditions? And of course it goes the other way too: You can usually do imperative things in functional languages but they often won’t be as elegant or efficient as The (functional) Way, and they may also confuse other coders who are reading the source in a functional frame of mind Algorithms for Approximation: read online download online Algorithms for Approximation: Proceedings of the 5th International Conference, Chester, July 2005 pdf, azw (kindle). That cell contains the value of f acting on the first element of the original stream, and a tail. The tail is created with fmap acting on the rest of the original stream. Equipped with fmap, we can now attempt to take the first step towards generating our triples: apply the function ints(1, z) to each element of the stream intsFrom(1): fmap(intsFrom(1), [](int z) { return ints(1, z); }); The result is a Stream of Streams of integers of the shape: But now we are stuck The Functional Treatment of download here read online The Functional Treatment of Parsing (The Springer International Series in Engineering and Computer Science).

Currying is a method that enables you to break an N-argument function to N single argument calls. In order to demonstrate currying, here we will use the same 3D Distance function as in the previous example: Now we will use the following generic higher-order function for breaking three parameter functions to a list of single argument functions: static Func>> Curry(Func function) { return a => b => c => function(a, b, c); } This function will break the three argument function into a set of three single argument functions (monads) , source: Global Analysis in Linear Differential Equations (Mathematics and Its Applications) download online Global Analysis in Linear Differential Equations (Mathematics and Its Applications). Last among our board creation functions is new-board: The code first creates the initial, empty board and gets the max position. Assuming that you’re using five rows, the max position will be 15. Next, the function uses (range 1 (inc max-pos)) to get a list of numbers from 1 to 15, other­wise known as the board’s positions ref.: Theory and Application of download for free Theory and Application of Graphs (Network Theory and Applications) pdf, azw (kindle). The answer to this question goes to the heart of programming: it’s about composability. We humans solve complex problems by splitting them into smaller subproblems. This is a recursive process, we split subproblems into still smaller pieces, and so on ref.: Introduction to Functional download pdf Introduction to Functional Programming Systems Using Haskell (Cambridge Computer Science Texts) book. Let’s see what a functional equivalent looks like. Create a new playground file and add the same initial structure: import Foundation let words = ["Cat", "Chicken", "fish", "Dog", "Mouse", "Guinea Pig", "monkey"] typealias Entry = (Character, [String]) func buildIndex(words: [String]) -> [Entry] { return [Entry](); } println(buildIndex(words)) At this point, the println statement will output an empty array: The first step toward building an index is to transform the words into an array that contains only their first letters , e.g. ML with Concurrency: Design, download epub download ML with Concurrency: Design, Analysis, Implementation, and Application (Monographs in Computer Science). Let’s also get rid of any false-y (false, null, "", etc.) values using another handy Underscore.js function. From here, we can write a function that generates our arrays using another built-in JavaScript collection method, named filter 20, that filters an array based on a condition. function makeArrayCount(keys, arr) { // for each of the unique tagNames return keys.map(function(key) { return [ key, // Find all the elements in the full list of tag names that match this key // and count the size of the returned array. arr.filter(function(item) { return item === key; }).length ] }); } We can now easily create the data structure that pack requires by mapping our list of arrays. var packData = makeArrayCount(tagNamesUnique, tagNames).map(function(tagArray) { return { className: tagArray[0], package: "cluster", value: tagArray[1] } }); Finally, we can pass our data to D3 and generate DOM nodes in our SVG, one circle for each unique tag name, sized relative to the total number of times that tag name appeared in CrisisNET’s API response. function setGraphData(data) { var node = svg.selectAll(".node") // Here's where we pass our data to the pack object. .data(bubble.nodes(data) .filter(function(d) { return !d.children; })) .enter().append("g") .attr("class", "node") .attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ")"; }); // Append a circle for each tag name. node.append("circle") .attr("r", function(d) { return d.r; }) .style("fill", function(d) { return color(d.className); }); // Add a label to each circle, using the tag name as the label's text node.append("text") .attr("dy", ".3em") .style("text-anchor", "middle") .style("font-size", "10px") .text(function(d) { return d.className } ); } Putting it all together, here’s the setGraphData and makeArray functions in context, including a call to CrisisNET’s API using jQuery (you’ll need to get an API key 21 ) Unix Test Tools and Benchmarks download pdf read Unix Test Tools and Benchmarks Methods and Tools to Design, Develop, and Execute Functional, Structural, Reliability, and Regression Tests pdf, azw (kindle), epub.
