Lab resources

Sample solutions: I've posted the following page for lab sample solutions Quizzes: the three term quizzes will be held in the lab sessions on Feb. 5, Feb. 26, and Mar. 26.

There will be six labs for the term, each worth 6% for a total of 36%.

Labs and the project will be distributed and submitted via our usual git processes, discussed in the overviews below.

All labs are due at midnight on their assigned due date.
Late penalties will be 10% for submissions that are late by less than 24 hours, 25% for submissions that are late by 24-48 hours, and 40% for submissions that are late by 48-72 hours. No submissions will be accepted for grading more than 72 hours after the posted deadline.

  (the Apr. 9th lab will be used for project presentations)
• Bonus lab optimization (due Apr. 11)

• Advice!
  Part 1: Compiler writing in general, and working with lex/yacc in particular, tends to be detailed and somewhat finicky work. Start your labs and project early, leave yourself the opportunity to step away from it for a night if you need to.
  Part 2: Clarification: your lowest lab mark can be replaced with your project mark to improve your grade.

• getting lab/project feedback (through git)
  - once the instructor has posted it, you'll notice through "ssh csci info" that you have a new server-side repository, e.g.
  csci439/yourname/feedback
  Clone this repository, and inside you'll find files with feedback on the labs so far (and eventually for the project also)
  Whenever the instructor pushes new feedback you can use pull in the repo to get the latest results.

• Review/prep for the labs
