  Everything You Thought You Knew About Learning Is Wrong

Taking notes during class? Topic-focused study? A consistent learning environment? All are exactly opposite the best strategies for learning. Really, I recently had the good fortune to interview Robert Bjork, director of the UCLA Learning and Forgetting Lab, distinguished professor of psychology, and massively renowned expert on packing things in your brain in a way that keeps them from leaking out. And it turns out that everything I thought I knew about learning is wrong. Here’s wh...

  In-memory key-value store in C, Go and Python

Subtitle: Wow Go’s net library is fast On paternity leave for my second child, I found myself writing an in-memory hashmap (a poor-man’s memcached), in Go, Python and C. I was wondering how hard it would be to replace memcached, if we wanted to do something unusual with our key-value store. I also wanted to compare the languages, and, well, I get bored easily! The code is on github as Key-Value-Polyglot. Each version implements enough of the get and set commands from the mem...

  Facebook open sources its C++ library named Folly

Recently, Facebook open sourced its low level C++ function library for its internal use named Folly. Folly is an open sourced C++11 component library, it provides functions similar to what boost and std libraries provide, including string, vector and memory allocation, bit operation etc, to fulfill large scale high performance requirements.Currently Folly is tested with gcc4.6 on some 64 bit systems such as Fedora 17, Ubuntu 12.04 and Debian wheezy, it may also be OK on other 64 bit platforms wi...

  Data governance Challenges and solutions in Apache Hadoop

Do you understand meaning of data governance? This is taken as most critical part of an organization that deals with sensitive data of an enterprise. If organization wanted to know who is accessing their sensitive data and what action has been taken by the viewers then data governance is wonderful solution to consider. In this article, we will discuss on data governance solutions and what are the challenges that are faced by organization during implementation of data governance. We will also dis...

  Never create Ruby strings longer than 23 characters

Looking at things through a microscopesometimes leads to surprising discoveries Obviously this is an utterly preposterous statement: it’s hard to think of a more ridiculous and esoteric coding requirement. I can just imagine all sorts of amusing conversations with designers and business sponsors: “No… the size of this <input> field should be 23… 24 is just too long!” Or: “We need to explain to users that their subject lines should be les...

  Substitute of Right Click Computer to Open Manage

I believe some of us may encounter some strange problems when we expect something normal to happen when we operate on our computer. On Windows 7, we may sometimes want to manage our service or applications by opening service manager.But somehow we may find that we cannot open it by clicking on Start->Right click on Computer->Manage.It may prompt some error message to tell us we cannot open the service manager. Then what to do? Here is a way to open it,goto Start->Run,then type "com...

  Products born for Cloud

Cloud computing has become increasingly popularity among companies. It greatly saves the investment of infrastructure and training with everything is running on cloud, it also improves the accessibility and flexibility of service provided by companies. With its popularity, many products are born or becoming popular to help build and move the apps to the cloud. Some well known names of these products are Vagrant, Docker/LXC, Chef and OpenStack. These tools can help create, test and deploy applica...

  Programming Languages for Machine Learning Implementations

Machine learning algorithms have a much better chance of being widely adopted if they are implemented in some easy-to-use code. There are several important concerns associated with machine learning which stress programming languages on the ease-of-use vs. speed frontier.Speed The rate at which data sources are growing seems to be outstripping the rate at which computational power is growing, so it is important that we be able to eak out every bit of computational power. Garbage collected la...

  Pointers, arrays, and string literals

A recently posted question on Stack Overflow highlighted a common misconception about the role of pointers and arrays held by many programmers learning C.The confusion stems from a misunderstanding concerning the role of pointers and strings in C. A pointer is an address in memory. It often points to an index in an array, such as in the function strtoupper in the following code:void strtoupper(char *str) { if (str) { // null ptr check, courtesy of Michael while (...
