<![endif] Brandon.Si(mmons) RSS Art Code Misc All About me Oct 24 th , 2009 12:16 am I’ve written this brief tutorial on haskell’s State monad to help bridge some of the elusive gaps that I encountered in other explanations I’ve read, and to try to cut through all the sticky abstraction. This is written for someone who has a good understanding of the Maybe and List monads, but has gotten stuck trying to understand State. I hope it’s helpful! To understand a monad you look at it’s datatype and then at the definition for bind ( >>= ). Most monad tutorials start by showing you the data declaration of a State s a in passing, as if it needed no explanation: 1 newtype State s a = State { runState :: s -> ( a , s ) } But this does need explanation! This is crazy stuff and nothing like what we’ve seen before in the list monad or the Maybe monad: ...

A Fistful of Monads Table of contents Zippers We've seen how monads can be used to take values with contexts and apply them to functions and how using >>= or do notation allows us to focus on the values themselves while the context gets handled for us. We've met the Maybe monad and seen how it adds a context of possible failure to values. We've learned about the list monad and saw how it lets us easily introduce non-determinism into our programs. We've also learned how to work in the IO monad, even before we knew what a monad was! In this chapter, we're going to learn about a few other monads. We'll see how they can make our programs clearer by letting us treat all sorts of values as monadic ones. Exploring a few monads more will also solidify our intuition for monads. The monads that we'll be exploring are all part of the mtl package. A Haskell pack...

CentralNotice Hunt–McIlroy algorithm From Wikipedia, the free encyclopedia Jump to: navigation , search In computer science , the Hunt–McIlroy algorithm is a solution to the longest common subsequence problem . It was one of the first non-heuristic algorithms used in diff . To this day, variations of this algorithm are found in incremental version control systems , wiki engines , and molecular phylogenetics research software. The research accompanying the final version of Unix diff , written by Douglas McIlroy , was published in the 1976 paper "An Algorithm for Differential File Comparison", co-written with James W. Hunt , who developed an initial prototype of diff.

CentralNotice Linear congruential generator From Wikipedia, the free encyclopedia Jump to: navigation , search A linear congruential generator ( LCG ) is an algorithm that yields a sequence of pseudo-randomized numbers calculated with a discontinuous piecewise linear equation . The method represents one of the oldest and best-known pseudorandom number generator algorithms. [ 1 ] The theory behind them is relatively easy to understand, and they are easily implemented and fast, especially on computer hardware which can provide modulo arithmetic by storage-bit truncation. The generator is defined by the recurrence relation : where is the sequence of pseudorandom values, and – the " modulus " – the "multiplier" – the "increment" – the "seed" or "start value" are integer constants that specify the generator. If c = 0, the generator is often called a multiplicative...

CentralNotice Change-making problem From Wikipedia, the free encyclopedia Jump to: navigation , search The change-making problem addresses the following question: how can a given amount of money be made with the least number of coins of given denominations?

<![endif] Educated Guess About Linkshare archives Nimrod Priell Imagine you’re a lumberjack, and you want to ship a whole forest to some far away place. You’d want to make sure you pack it as tight as you can. No, wait. Imagine you’re a software engineer and you want to transfer a huge forest (just a bunch of trees, or rooted undirected acyclic graphs, that is) across the Internet. How would you do it efficiently? Let’s make it clear that we’re looking for a way to transfer the tree structure. That is separate from transferring the contents of the nodes. If the trees you’re representing are, for example, social network influences (e.g tweets emitted from a certain person and retweeted by his followers, and theirs, and so on), you can keep the names of the persons involved, the tweet and the time it was retweeted at in a separate message. Then you map each node to a num...

InstantClick Documentation Click test InstantClick is a JavaScript library that dramatically speeds up your website, making navigation effectively instant in most cases. Follow @instantclickjs Despite huge bandwidth increases, websites don’t get much faster. This is because the biggest bottleneck in loading web pages is latency. 1 Latency is inevitable with today’s internet architecture so InstantClick cheats by preloading links you are likely to click on. Before visitors click on a link, they hover over that link. Between these two events, 200 ms to 300 ms usually pass by ( test yourself here ). InstantClick makes use of that time to preload the page, so that the page is already there when you click. On mobile devices, preloading starts on “touchstart”, letting 300 ms (Android) to 450 ms (iOS) for preloading the page. 2 If you want your website to not be flooded by reques...
