Take college and university courses online completely free

The term was coined in 2008 by David Cormier, manager of web communications and innovations at the University of Prince Edward Island. The first MOOC was created the previous year, at Utah State University. Today, there are hundreds of thousands of courses available online at no cost. You can study anything from business to zoology in your own home at no cost. MOOCs are designed like college courses but are available to anyone anywhere in the world, at no cost. Coursera is perhaps the most well-known of the online education facilitators. EdX is another non-profit course site created by founding partners Harvard and MIT and based in Cambridge, Massachusetts.

How MySpace Tested Their Live Site with 1 Million Concurrent Users. This is a guest post by Dan Bartow, VP of SOASTA, talking about how they pelted MySpace with 1 million concurrent users using 800 EC2 instances.

How MySpace Tested Their Live Site with 1 Million Concurrent Users

I thought this was an interesting story because: that's a lot of users, it takes big cajones to test your live site like that, and not everything worked out quite as expected. I'd like to thank Dan for taking the time to write and share this article. In December of 2009 MySpace launched a new wave of streaming music video offerings in New Zealand, building on the previous success of MySpace music.

These new features included the ability to watch music videos, search for artist’s videos, create lists of favorites, and more. The anticipated load increase from a feature like this on a popular site like MySpace is huge, and they wanted to test these features before making them live. If you manage the infrastructure that sits behind a high traffic application you don’t want any surprises. Test Environment Architecture figure 1.

Pragmatic Programming Techniques. Google's Mind-Blowing Big-Data Tool Grows Open Source Twin. Silicon Valley startup MapR has launched an open source project called Drill, which seeks to mimic a shocking effectively data-analysis tool built by Google Mike Olson and John Schroeder shared a stage at a recent meeting of Silicon Valley’s celebrated Churchill Club, and they didn’t exactly see eye to eye.

Running Hadoop on Windows « Hayes Davis

Hadoop is a an open source Apache project written in Java and designed to provide users with two things: a distributed file system (HDFS) and a method for distributed computation. It’s based on Google’s published Google File System and MapReduce concept which discuss how to build a framework capable of executing intensive computations across tons of computers. Something that might, you know, be helpful in building a giant search index. Read the Hadoop project description and wiki for more information and background on Hadoop.

Abxda : QUE TAL!!!!! U.S. Geological... Brief introduction to Scala and Breeze for statistical computing. Introduction In the previous post I outlined why I think Scala is a good language for statistical computing and data science.

Brief introduction to Scala and Breeze for statistical computing

In this post I want to give a quick taste of Scala and the Breeze numerical library to whet the appetite of the uninitiated. This post certainly won’t provide enough material to get started using Scala in anger – but I’ll try and provide a few pointers along the way. It also won’t be very interesting to anyone who knows Scala – I’m not introducing any of the very cool Scala stuff here – I think that some of the most powerful and interesting Scala language features can be a bit frightening for new users.

An introduction to evolution The definition Biological evolution, simply put, is descent with modification.

An introduction to evolution

This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life. The explanation Biological evolution is not simply a matter of change over time.

De tidigaste organismerna var encelliga och levde för tre och en halv miljarder år sedan.

Evolution

Alla organismer har genomgått en evolution och skillnaderna mellan dem beror på gradvisa anpassningar till olika livsmiljöer. Evolutionära förändringar har oftast lett till mer komplexa former men ibland har organismer förenklats, till exempel parasiter. Med evolutionsteorin kunde Charles Darwin förklara hur olika arter av växter och djur har förändrats och utvecklats sedan livet började på jorden. Av allt liv som funnits har 99,9% dött ut. Av nu levande flercelliga arter har nästan två miljoner hittills beskrivits. Fem frågor om evolution 1. Natural Selection. Darwin, a naturalist's voyage around the world - CNRS sagascience.

Evolution. Understanding Evolution. The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. That all changed due to the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria. Read the rest of the story here | See the Evo in the News archive. The Cell and its Organelles. Society for General Microbiology. Types of Boundaries.

Understanding Plate Motions. Scientists now have a fairly good understanding of how the plates move and how such movements relate to earthquake activity. Most movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Eye-eye, Popeye! Seeing Iron in Food Many foods contain iron, which blood cells need in order to carry oxygen. A protein called heme contains the iron (II) ion at its center. Blood vessels in the lungs, where oxygen concentration is high, allow the heme to bond to the oxygen molecule to create oxyhemoglobin, which is then transported to oxygen-hungry tissues throughout the body.
