Four short links: 11 March 2013
- Adventures in the Ransom Trade — between insurance, protection, and ransoms, Sean Gourley describes it as “one of the more interesting grey markets.” (via Sean Gourley)
- About High School Computer Science Teachers (Selena Deckelmann) — Selena gets an education in the state of high school computer science education.
- Learning From Big Data (Google Research) — the Wikilinks Corpus: 40 million total disambiguated mentions within over 10 million web pages [...] The mentions are found by looking for links to Wikipedia pages where the anchor text of the link closely matches the title of the target Wikipedia page. If we think of each page on Wikipedia as an entity (an idea we’ve discussed before), then the anchor text can be thought of as a mention of the corresponding entity.
- Teens Have Always Gone Where Identity Isn’t — if you look back at one of the first dominant social platforms, AOL Instant Messenger, it looks a lot like the pseudonymous Tumblr and Snapchat of today in many respects. You used an avatar that was not your face. Your screenname was not indexed and not personally identifiable (mine was Goober1310).
