Clojure. Transducers, Reducers and Other Stuff
Written by Andrei Zhlobich
Transducers have become quite popular recently. It’s a new feature of the non-released Clojure 1.7. As of writing this, Сlojure 1.7-alpha5 version is the latest development release, but there also appeared a fair number of ports of transducers for such languages as Python , Ruby , JavaScript , PHP , Java , C++ , Lua , Erlang . To tell the truth, it’s a bit disconcerting, the library of reducers was added long ago (in Clojure 1.5). But no one said anything about them; nothing was ported, though they seem to be performing similar things. Or not? Let’s find out what these reducers & transducers are made for (do we really need them?), how they work and how we can use them… Finally, we will decide whether it’s time to throw reducers away.

The Nth Fibonacci Number in O(log N)
Written by Ivan Yurchenko
Reading an article about getting a job in ABBYY, I came across the following task: Find the Nth Fibonacci Number in O(N) time of arithmetic operations. Thinking about it, I realized that the only solutions coming to my mind were those operating in O(n) time. But I found a better solution later. I am going to use the following denotation of sets: - non-negative integers — positive integers According to various mathematic traditions, a set of natural numbers can either contain 0 or not. Therefore, it’s preferred to indicate it explicitly in international mathematic texts. The Solution Donald E. Knuth provides a matrix identity of the following form: The identity is provided without any proof, but it’s quite easy to prove it by induction. The matrix on the right is called Q-matrix. Let’s indicate: According to the identity, . Thus, to calculate , we should calculate matrix and take the firstRadix Trees

Having read some articles about tries (aka prefix trees aka radix trees), I decided to write one of my own. Today we are going to talk about a trie implementation in C++. We will also compare a string search with AVL and Radix tree. Intro A trie is an ordered tree data structure that is used to store a dynamic set or associative array where the keys are usually strings. We are going to take a look at the implementation of prefix trees for storing ASCII strings. Each string ends with a terminal symbol that will never repeat in a string again. To indicate terminal symbols in pictures and examples, we will use the dollar sign. To indicate them in the code, we’re going to use the null symbol. Thus, in our implementation the strings will be standard C ones, which allows to use the standard string.h library. All the mentioned above shouldTransactional Memory: History and Development
Written by JIghtuse
Definition Parallel programming is difficult. When using systems with common memory, you can’t go without synchronization of parallel processes/threads access to the common resource (memory). The following are used for it: locks (mutex); lock-free algorithms (lockless); transactional memory. Transactional memory is a technology of concurrent threads synchronization. It simplifies the parallel programming by extracting instruction groups to atomic transactions. Concurrent threads operate paralleled till they start to modify the same memory chunk. For example, operations of nodes adding to the red/black tree (animation in the heading) can operate in parallel in several threads. /* Move item from one list to another */ int move(list *from, list *to) { __transaction_atomic { node *n = pop(from); push(to, n); } } Concurrency management approach with transactional memory use is called optimistic: we think that threads operate independently of one another and rarely change the same data. In this case most transactions areJulia Set

As you might have guessed, this article focuses on lock-free queues. Queues can be different. They can differ in the number of producers and consumers (single/multi producer — single/multi consumer, 4 variants). They can be bounded, on the basis of a pre-allocated buffer, and unbounded, on the basis of a list. They can either support priorities, or not. They can be lock-free, wait-free or lock-based, with the strict (fair) and not strict (unfair) conformance to FIFO, etc. These types of queues are described in detail in the article by Dmitry Vyukov . As a rule, the more specialized requirements to a queue are, the more efficient its algorithm is. In this article, we will consider the most common version of queues – multi-producer/multi-consumer unbounded concurrent queues without the support of priorities. I guess the queue is the favorite data structure for researchers. On the one hand, it’s really simple;How I built my first Android Game and realized creativity is all about iterations

If one event occurrence either increases, or decreases the probability of other event occurrence, such events are called dependent. Probability theory does not study cause-and-effect relations. Therefore, dependent events are not necessarily effects of each other, the relation is not always obvious. For example, “ a person has blue eyes ” and “ a person knows Arabic ” are dependent events, as Arabian people rarely have blue eyes.

Being a fan of scientism , I am going to tell you about the nature of time, causality and time travels. Time According to classical mechanics, time is absolute and invariable in the sense that when moving from one reference system to another one, time frames do not change: (x, y, z, t) are coordinates in the old frame, while (x', y', z', t') are coordinates in the new one. It is expected that one system moves in-parallel along x axis at v speed. (adsbygoogle = window.adsbygoogle || []).push({}); It’s the so-called Galilean transformation , which is what happens to coordinates when reference systems are changed. In the Galilean sense, there’s just one “time flow” in the Universe and time coordinates are the same for all objects. At that, classical mechanics does not treat the time arrow originality in any way. Moreover, the concept of the flow of timeAVL Trees

The pictures depicted in regular plots about intellectual piracy often use the image of a starving poet who can not get an adequate fee for his work and talent.
