Exploring the Relationships Between Tech Skills (Visualization) 65 65

Nerval's Lobster writes: Simon Hughes, Dice's Chief Data Scientist, has put together an experimental visualization that explores how tech skills relate to one another. In the visualization, every circle or node represents a particular skill; colors designate communities that coalesce around skills. Try clicking "Java", for example, and notice how many other skills accompany it (a high-degree node, as graph theory would call it). As a popular skill, it appears to be present in many communities: Big Data, Oracle Database, System Administration, Automation/Testing, and (of course) Web and Software Development. You may or may not agree with some relationships, but keep in mind, it was all generated in an automatic way by computer code, untouched by a human. Building it started with Gephi, an open-source network analysis and visualization software package, by importing a pair-wise comma-separated list of skills and their similarity scores (as Simon describes in his article) and running a number of analyses: Force Atlas layout to draw a force-directed graph, Avg. Path Length to calculate the Betweenness Centrality that determines the size of a node, and finally Modularity to detect communities of skills (again, color-coded in the visualization). The graph was then exported as an XML graph file (GEXF) and converted to JSON format with two sets of elements: Nodes and Links. "We would love to hear your feedback and questions," Simon says.

Windows 10 Shares Your Wi-Fi Password With Contacts 487 487

gsslay writes: The Register reports that Windows 10 will include, defaulted on, "Wi-Fi Sense" which shares wifi passwords with Outlook.com contacts, Skype contacts and, with an opt-in, Facebook friends. This involves Microsoft storing the wifi passwords entered into your laptop which can then be used by any other person suitably connected to you. If you don't want someone's Windows 10 passing on your password, Microsoft has two solutions; only share passwords using their Wi-Fi Sense service, or by adding "_optout" to your SSID.

iOS 9 To Have Ad Blocking Capabilities 161 161

An anonymous reader writes: iOS 9 will reportedly carry ad blocking capabilities for it's Safari browser when it is released later this year. The feature wasn't rolled out with the usual fanfare one might expect, and flew under the radar. ZDNet reports: "It's not immediately clear why the new ad-blocking privacy feature was included in iOS 9, due out later this year. After all, the iPhone and iPad maker has its own advertising network -- even if its success was limited (which is putting it nicely). What's clear is that allowing ad-blockers in iOS 9 could deliver a serious blow to Google, the biggest rival to Apple in the mobile space, because advertising remains a massive portion of the search giant's income."
