Mark’s Birthday Hack!

Mark:

  • realized security situation for serializing corkbird state is going to be complicated; have to deal with applet security
  • error reporting now works; this is good, since there are a lot of errors
  • processing sketches use the default Java package, but you can’t import the default package, apparently — figuring out what to do about that

Emily:

  • working on personal site (duien.com)
  • it aggregates twitter and delicious, now it can pull new entries in

Alex:

  • more code delving: figured out file format for new Twidor logs
  • wants to rework his gross old Python code and update it so it works with new Twidor logs
  • emailed out a bunch of questions to the group, concerned about training classifiers on keystrokes that have already been corrected

Lindsey:

  • Helped write an assignment for c311, answered a bunch of questions at office hours.
  • tonight: working on homework for Computational Complexity

Special President’s Day Hack.

Mark:

  • got in to gradschool! gatech phd program ahoy!
  • working on corkbird: uploading sketches works, but need to be fancier about pulling apart jars.
  • close to demo-able state (it’s looking pretty sweet)

Tejus:

  • making a signup form for scmple (www.scmple.com). It has a really cool ajax.
  • Startup Riot is coming up on Wednesday, getting ready.

Alex:

  • got into gradschool! Indiana phd program ahoy!
  • answering emails, looking at some blogs
  • polishing up old log-parsing code from miniqwerty research (typo-detection machine learning rides again!)
