Announcements

Important announcements related to the course will be posted here. Please check this page daily.

CourseEvalUM is open Dec 1 through Dec 13. Please submit an evaluation for this and all your other courses.

  • Dec 20 - Project 6 and end-of-semester final grades now visible on grades server. Curve was 24 As, 36 Bs, 28 Cs, 7 Ds, and 11 Fs.

  • Dec 15 - Final exam scores are posted. (Manual grading for project 6 will still take several more days.)

  • Dec 10 - Special office hours for Monday, December 14:
    • 10-11am - Bryan
    • 11am-1pm - Young

    • 2-3pm - Young
    • 3-4pm - Mark
    • 4-6pm - final exam in HJP 0226.

  • Dec 9 - Project 7 (Ruby on Rails web database) posted. This project is worth no points and is just for fun.

  • Dec 9 - Updated Project 6 sim.rb so when performing simulations it now outputs simulation parameters before simulation messages.

    This change is optional (original sim.rb still works for submissions) and was added so that the simulation output (if saved in a file) may be passed directly to the simulation display/verify routines for debugging.

  • Dec 5 - Submit server now accepting Project 6 submissions. You may use your release tokens at any time, so go ahead and submit even if you only part of the project working.

  • Dec 2 - Project 6 has been posted. It will be due Dec 11.

  • Dec 1 - Practice problem 7 and its solution have been posted online. Quiz 4 this Friday on multhreading will resemble problem 1 from Practice problem 7.

  • Nov 30 - The final exam for 330 will be held Monday, December 14 from 4-6pm in HJP 0226.

  • Nov 23 - Bryan's office hours Tue 3-5pm are cancelled.

  • Nov 19 - Midterm 2 scores are now available on the grades server.

  • Nov 19 - Description here of some interesting courses Nelson is teaching over the Winter break.

  • Nov 18 - Class on Wed, Nov 25 is cancelled. Enjoy the holiday! Office hours are also cancelled that day.

  • Nov 16 - Project 5 scores now available on the grades server.

  • Nov 9 - Quiz 3 scores now available on the grades server. Quizzes 1-3 and their solutions have been posted here.

  • Nov 9 - Project 5 deadline has been changed to Sat Nov 14.

  • Nov 9 - Midterm 2 material will include parsing, OCaml, lambda calculus, relating functions and oo programming, and type systems and bindings. It will not include parameter passing or threads. Practice problem 6 now available here.

  • Nov 9 - Note you will fail the public_scheme test on the submit server if your basic.scm file contains extra header lines such as "#lang ...", "; ...", or "#reader ...". Remove these lines before submitting your project. You may need to use a normal text editor since DrScheme will not display these lines.

  • Nov 9 - Minor changes to Project 5 files in p5.zip. Modified public_scheme.scm to add (load "basic.scm"), and goTest.rb to add "guile -s public_scheme.scm".

  • Nov 8 - Project 5 submission to the submit server are now accepted. Public tests & expected outputs are now available on the project web page here.

  • Nov 3 - Quiz 3 has been scheduled for this Friday, 11/6. It will be on the lambda calculus.

  • Nov 3 - Project 4 & quiz 2 scores are now visible on the grades server.

  • Oct 29 - Midterm 2 will be held on Wednesday, November 18 in lecture. The exact topics will be announced later, but will include at least parsing, OCaml, and lambda calculus.

  • Oct 28 - Project 5 has been posted. Submit server setup will be ready later this week.

  • Oct 19 - Jeff's office hours on Wed, Oct 21 will be covered by Youngil (in the TA room).

  • Oct 16 - Midterm 1 scores are now available on the grades server. Mean score was 73/100.

  • Oct 16 - Project 4 files have been updated to provide public tests & expected outputs. The submit server is ready to accept submissions. You can use your project 4 release tokens even without passing all public tests, so submit early & submit often.

  • Oct 14 - Increased project 3 release token number and regeneration rate. Basically you now have an almost unlimited number of release tokens, and you can use them any time to look at release test results.

  • Oct 13 - Updated Project 4 to eliminate 2 functions nnf & to_nnf.

  • Oct 13 - Project 2 scores have been uploaded to the grades server.

  • Oct 10 - Project 3 and Project 4 have been posted. Project 3 is not a full project; instead it is designed as a warmup exercise for OCaml. Project 3 is ready to accept submissions on the submit server. Project 4 description has been posted, but public tests & their expected output will not be available for a few more days.

  • Oct 5 - Midterm 1 will be given Wed, Oct 14 during lecture. It will cover material up to CFGs (not including parsing). Practice problems & sample midterms are available here.
