First Annual International Twitter Links on Atlhack Notes Day!

alex (rudnick):

• refactoring the code that builds training sets for typo detection, thinking about new attributes
• wants to learn about Python annotations or decorators or whatever you call them, has a cute design for the parser
• headed to talk with IU professors tomorrow

lindsey:

• helping greet new gradstudents
• algorithms/complexity homework tonight (now caught up on grading and compilers hw!)

tejus:

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
