  • Continuing The Law of Group Polarization. Slow going. Mostly because there is so much good stuff.
    • Overall, I’m arguing that viewing Group Polarization through the lens of Connectivism, we can see how networked communities are often driven into bubbles and that property can be used to evaluate the trustworthiness of an information source. This has implications for design at different levels of abstraction.At the UI level, it implies that giving a user more interactive control over the makeup of their news feed can inform them about the range of diversity in views about a particular topic and where their feed falls on that spectrum. Because this implies the presence of a larger group, it it is possible to provide the user with the means (through direct manipulation) to interactively adjust the makeup of their news feeds and expose them to more trustworthy sourcesAt the document level, it imples that a mix of lexical and link analysis should be sufficient to allow for indexing a document on a trustworthiness scale.At the network level, it implies that the relationships of documents within a network should be sufficient to place documents on a trustworthiness scale.
    • Page 182 – And when one or more people in a group know the right answer to a factual question, the group is likely to shift in the direction of accuracy.
      • This is the effect of the Star Pattern. So how does someone find the right answer?
    • Looking around for automated ways of doing Delphi Method
    • Page 184: Group polarization has particular implications for insulated “outgroups” and (in the extreme case) for the treatment of conspiracies. Recall that polarization increases when group members identify themselves along some salient dimension, and especially when the group is able to define itself by contrast to another group. Outgroups are in this position-of self-contrast to others-by definition. Excluded by choice or coercion from discussion with others, such groups may become polarized in quite extreme directions, often in part because of group polarization. It is for this reason that outgroup members can sometimes be led, or lead themselves, to violent acts
    • Stopped at pg 186 – III. DELIBERATIVE TROUBLE.
  • Looking at IBM Bluemix briefly in case we have to go down that route
    • Registered.
    • Chrome, or at least the way I set up Chrome and bluemix do not get along. trying Firefox. Still not great, but better.
    • Since it looks like we’re not going to do wacky mash-ups, back to work on the rating app.
  • Hit the MySql max_packet limit. Changed to 4M. Other follow-on changes:
## of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 64M
innodb_additional_mem_pool_size = 8M
## Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 20M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
