Mathematics Collaboration, Risk, Visualisation, and SemWeb

  1. Enabling Massively Parallel Mathematics Collaboration — Jon Udell writes about Mike Adams whose WordPress plugin to grok LaTeX formatting of math has enabled a new scale of mathematics collaboration.
  2. 2845 Ways to Spin The Risk — introduction to the ways in which our perception of risk (and numbers in general) can be distorted by how it is presented. (via titine on Twitter)
  3. Logstalgia — OpenGL app to visualize Apache log files.
  4. 4Store — “scalable RDF storage”. 4store was designed by Steve Harris and developed at Garlik to underpin their Semantic Web applications. It has been providing the base platform for around 3 years. At times holding and running queries over databases of 15GT, supporting a Web application used by thousands of people.

Semweb, Comedy Java, Mobile Spyware, Crypto

  1. On Data Reconciliation Strategies and Their Impact on the Web of DataFor years, I’ve been a fairly vocal advocate for the elegance and scalability of a-posteriori reconciliation via equivalence mappings as a superior mechanism (scale-wise) to a-priori reconciliation efforts… but this started to change very rapidly once I started working for Metaweb and saw first hand how much more effective a-priori reconciliation can be, even if drastically more expensive and limiting in the data acquisition front.

  2. Java Spring’s Biggus Dickus EffectNonstop administrative debris as dadaist poetry. Écriture automatique of the programming office manager or his parrot. (via mattb on Delicious)
  3. Arabic Blackberry Spyware — update pushed out to Arabic Blackberries CC:ed all email to the authorities. A powerful case for multi-distro platforms, which reduces the size of the market captured with one distro is pwned like this.
  4. NaCl – Networking and Cryptography Library — open source high-level crypto library. NaCl (pronounced “salt”) is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl’s goal is to provide all of the core operations needed to build higher-level cryptographic tools. Of course, other libraries already exist for these core operations. NaCl advances the state of the art by improving security, by improving usability, and by improving speed. Creator of qmail is one of the developers. (via Simon Willison)

Weaker Copyright Good, YQL.gov, GeoSPARQL, Happiness

  1. Harvard Study Finds Weaker Copyright Protection Has Benefited Society (Michael Geist) — Given the increase in artistic production along with the greater public access conclude that “weaker copyright protection, it seems, has benefited society.” This is consistent with the authors’ view that weaker copyright is “uambiguously desirable if it does not lessen the incentives of artists and entertainment companies to produce new works.” (read the original paper)
  2. Using Public Data for Good With the Power of YQLThe first part is a new batch of YQL tables providing data on the U.S. government, earthquake data, and the non-profit micro-lender Kiva. The second part is an incredibly easy way to render YQL queries on websites. After all, what good is data that no one can see?
  3. GeoSPARQL — RDF meets geo goodness. SELECT ?s ?p ?o WHERE { ?s gn:name "Dallas" . ?s ?p ?o } (via the geowanking mailing list)
  4. How To Be Happy in Business — this Venn diagram makes me happy. (via Ned Batchedler)

Google's Rich Snippets and the Semantic Web

There’s a long-time debate between those who advocate for semantic markup, and those who believe that machine learning will eventually get us to the holy grail of a Semantic Web, one in which computer programs actually understand the meaning of what they see and read. Google has of course been the great proof point of the power of machine learning algorithms. Earlier this week, Google made a nod to the other side of the debate, introducing a feature that they call “Rich Snippets.” Basically, if you mark up pages with certain microformats ( and soon, with RDFa), Google will take this data into account, and will provide enhanced snippets in the search results.

Tutorial: Add AB Meta Tagging to Your Blog

Start using Adaptive Blue's AB Meta format in your existing blogs.

Simplifying Semantic Tagging

Adaptive Blue has released a header/meta tag scheme to simplify semantic tagging of content items. From ReadWriteWeb: Semantic web company Adaptive Blue has published what it hopes will become a standard for publishers who want to signal in their header tags when a webpage is primarily about a particular book, film, wine or other type of objects … Called AB…
