Truthy What is Truthy? Truthy is a research project that helps you understand how memes spread online. We collect tweets from Twitter and analyze them. The name Truthy comes from a term coined by Stephen Colbert, truthiness, which describes claims that feel like they ought to be true, but aren't necessarily. What is a meme? How do you pick the memes for the Election Coverage tool? For the 'Candidates' election coverage selection, we have chosen the top four memes (by tweet volume) that contain "obama" or "biden" to signify the left, and those that contain "romney" or "ryan" for the right. For the 'Politics' selection, we determined the memes based upon the following criteria: #p2: Most popular left-leaning meme #ows: Most popular co-occurring left-leaning meme #topprog: Second most popular co-occurring left-leaning meme #dems: Official hashtag for democrats Of course this is only an illustration of the activity we observe. What is a diffusion network? What is astroturfing?
Datavisualization.ch Selected Tools logTool: Revealing the Hidden Patterns of Online Surfing Behavior logTool [onformative.com] is a data visualization tool that displays your online activity, based on data from the powerful network packet sniffing tool Carnivore. By analyzing the different IP addresses and ports, the visualization is able to determine and represent what kind of application or service sends or receives the packets. Developed for the magazine Weave, logTool was used to digest the surfing behavior of several interaction designers, artists and developers. The time period of a whole day was split into 288 timeslots, 5 minutes each, represented by a radial bar graph. Both tool and source code can be freely downloaded. See also Nebul.us and EyeBrowse.
Visualizing Device Utilization Device utilization is a key metric for performance analysis and capacity planning. In this post, I’ll illustrate different ways to visualize device utilization across multiple devices, and how that utilization is changing over time. As a system to study, I’ll examine a production cloud environment that contains over 5,000 virtual CPUs (over 600 physical processors). CPU utilization heat map Command Line Interface ToolsTabulated DataHighlighted Data3D Surface PlotAnimated DataInstantaneous ValuesBar GraphsVector GraphsLine GraphsTernary PlotsQuantized Heat Maps Device utilization can be defined as the time a device was busy processing work during an interval, so a device at 100% utilization is active doing work 100% of the time. For any given device type (CPUs, disks, network interfaces), and any number of devices (from a single device to a cloud of servers), we’d like to identify the following: Finally, we’d like to observe this all in realtime. These tools usually don’t handle scale. ).
Facebook Platlas: Social Media Atlas Reveals All User Actions Platlas - the Facebook Version [platlas.com] is not one of easiest interactive infographics around, as its attempts to provide a better understanding of the driving principles behind social media, and Facebook in particular. Branded as the "first ever social network ecosystem exploration tool", it starts from revealing the variety of actions users tend to take on the various social platforms available today. The center is the user profile, from which users interact with the icons present in the inner-most circle. Each icon represents a specific area on Facebook, such as Events, Photos, or Apps. The outer-most ring then shows the different features that can be performed, according to the inner-most area. More background information is available here.
El Patrón de los Números Primos: Prime Number Patterns by Jason Davies. For each natural number n, we draw a periodic curve starting from the origin, intersecting the x-axis at n and its multiples. The prime numbers are those that have been intersected by only two curves: the prime number itself and one. Below the currently highlighted number, we also show its sum of divisors σ(n), and its aliquot sum s(n) = σ(n) - n, which indicate whether the number is prime, deficient, perfect or abundant. Based on Sobre el patrón de los números primos by Omar E.
