Cameron's Triad page Akron is a new connection game played with marbles on a square grid. Two players, Black and White, strive to connect their edges of the board with pieces of their colour. Each turn a piece can be played at any empty board point, or a piece already on the board can be moved to any connected empty point. Most games in the connection family, such as the classics Hex and Y, tend to be hexagonal in nature to avoid problems with deadlocks in the plane. Akron solves this problem by letting players stack pieces over enemy blocks.

Semir Zeki: Beauty is in the brain of the beholder Beauty isn’t in the eye of the beholder – it’s in the brain, according to a 2011 paper in the online journal PLoS One. And in a very specific part of the braia, too: the medial orbito-frontal cortex, located just behind the eyes. That’s according to co-author of the new PLoS One paper and brain expert Professor Semir Zeki, of the University College London. He told EarthSky’s Beth Lebwohl: Philosophers have always been interested in: what is beauty, and what do all things that are experienced as beautiful have in common? And we are attacking these questions in an experimental setting. 20+ Tools to Create Your Own Infographics A picture is worth a thousand words – based on this, infographics would carry hundreds of thousands of words, yet if you let a reader choose between a full-length 1000-word article and an infographic that needs a few scroll-downs, they’d probably prefer absorbing information straight from the infographic. What’s not to like? Colored charts and illustrations deliver connections better than tables and figures and as users spend time looking back and forth the full infographic, they stay on the site longer. Plus, readers who like what they see are more likely to share visual guides more than articles. While not everyone can make infographics from scratch, there are tools available on the Web that will help you create your very own infographics. In this article, we’re listing more than 20 such options to help you get your messages across to your readers, visually.

its-time-industrialize-analytics from - StumbleUpon There's a lot of talk about advanced analytics these days - the use of data mining and predictive analytics is growing rapidly so lots of articles, books (like Tom Davenport's latest) and blog posts are being written. One of these was by Jeff Kelly over on TechTarget on Data analytics team’s needs and, while I agree with some of what was said, I am going to take issue with the idea that analytics is a cottage industry. There is a feeling that, because what analysts do is complex and hard for others to understand they should be allowed to swan around picking their own tools while being give lots of autonomy and plenty of freedom to experiment. This is, I believe, a very dangerous idea. It is time for organizations to take a stand and industrialize their advanced analytics efforts.

Kerckhoffs's Principle In cryptography, Kerckhoffs's principle (also called Kerckhoffs's desiderata, Kerckhoffs's assumption, axiom, or law) was stated by Auguste Kerckhoffs in the 19th century: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge. Origins[edit] In 1883 Auguste Kerckhoffs[1] wrote two journal articles on La Cryptographie Militaire,[2] in which he stated six design principles for military ciphers.

Create A Free Project Management System From Scratch Nicholas is a marketer & web designer based in Boston, MA with a specialty in high growth B2B startups. He is currently the Director of Marketing for Jebbit. For marketers who wear multiple hats, keeping project information streamlined can become an overwhelming task. Managing content, sales requests, client requests, etc., can often cause deadlines and project details to become lost in translation (or in a thread of emails). Without an enterprise project management system or custom intranet it may seem impossible to keep all of this data organized to maximize your production output. However there are tools out there to help you accomplish this completely for free.

Social Media's Critical Path: Relevance to Resonance to Significance - Brian Solis - The Conversation If social media warranted a mantra, it would sound something like this, “Always pay it forward and never forget to pay it back…it’s how you got here and it defines where you’re going.” This intentional form of alternative giving is referred to as “generalized reciprocity” or “generalized exchange.” The capital of this social economy is measured in these productive relationships and those relationships are earned through the acts of reciprocity, recognition, respect and benevolence. So how can businesses, which, one could argue, typically represent a “pay it backward” approach (ie, “pay me for my goods and services”), thrive in this environment? In my experience as a longtime social media observer who advises companies on how to successfully navigate the new media landscape, the key lies in embracing the linear concept of Relevance, Resonance, and Significance. To understand this model, it’s important we define the base unit for social media: the “social object.”

Bringing Down the House (book) The book's main character is Kevin Lewis, an MIT graduate who was invited to join the MIT Blackjack Team in 1993. Lewis was recruited by two of the team's top players, Jason Fisher and Andre Martinez. The team was financed by a colorful character named Micky Rosa, who had organized at least one other team to play the Vegas strip. This new team was the most profitable yet.

Across the board, in Johnson’s book and other sources it seems pretty clear that creativity is messy. Ideas need to be sloshing around or crashing in to one another to produce breakthroughs:

New technologies revolutionise Kanban Project Accelerator News The Kanban approach is gaining popularity in businesses across the world. Experts agree that as the world becomes fully connected, a non-stop, always-on communicative environment is changing the way we live and work, making project management increasingly difficult. More and more, project managers work with teams spread across the globe who often feel as if they are constantly being bombarded with data from dozens, sometimes even hundreds, of sources in real time. Graph (mathematics) The edges may be directed or undirected. For example, if the vertices represent people at a party, and there is an edge between two people if they shake hands, then this is an undirected graph, because if person A shook hands with person B, then person B also shook hands with person A. In contrast, if there is an edge from person A to person B when person A knows of person B, then this graph is directed, because knowledge of someone is not necessarily a symmetric relation (that is, one person knowing another person does not necessarily imply the reverse; for example, many fans may know of a celebrity, but the celebrity is unlikely to know of all their fans). This latter type of graph is called a directed graph and the edges are called directed edges or arcs. Vertices are also called nodes or points, and edges are also called arcs or lines.
