Project grades and feedback from your TA are now available on Omnivore, and final letter grades should be available soon on WebSIS.

Have a great IAP!

The group project is due tomorrow at 11am. Also due at 11am is your individual reflection about the project, so please don’t forget to fill that out.

Tomorrow is the last 6.031 class of the semester. We will have a brief wrap-up and summary of the course.

Quiz 2 grades are now available on Omnivore.

You can review your graded quiz on Gradescope. You will receive an email from Gradescope with details.

Quiz 2 solutions are posted on the web site.

As with all assignments, please bring grading issues or questions to instructor office hours. Gradescope has a “regrade request” feature, but we will not be using it.

Overall ps4 grades and grade reports are now available on Omnivore.

To see your beta autograde report, go to Didit, follow the link to your psets/ps4 page, and click “beta milestone.”

Your manual grade was assigned by staff inspection of your specs, tests, implementations, thread safety docs, and your response to code reviews.

If you have questions, please see the FAQ about grading questions.

We’ve made a correction to the Norn project specification handout, in the Web user interface section on Visualization.

The example there originally claimed to visualize:

wizards=gandalf@cosmos,saruman@cosmos;wizards,bagginses

but it was only showing the structure of the last subexpression in the sequence.

The visualization must include the full recursive structure of the input expression. For this longer input, while the set of recipients would be the same, the visualization must also show the operands of ;, of =, and of the , inside the definition of wizards.

If you have questions about this correction, your milestone meeting tomorrow is a great time to ask.

Quiz 2 will be on Monday, December 3, 11:05am-11:55am, in Walker 3rd floor gym. That’s the usual class time, but not the usual class location.

The quiz is 50 minutes long, so class will end early that day.

The quiz will cover readings 1-27, from the start of the semester through Little Languages. Any and all concepts from readings 1-27 may appear on the quiz, though you can expect more focus on topics from the second half of the class that weren’t covered by Quiz 1. Quizzes from previous semesters of 6.031 and 6.005 can be found in the quiz archive, although their content may differ from the topics we’ve discussed this semester (with greater divergence the farther back in time you go).

The quiz is on paper, so you will not need your laptop. It is closed-book, closed-notes, but you may bring a single 8.5×11″ double-sided page of notes, readable without a magnifying glass. The notes must be created by you, not anybody else, since the process of creating a crib sheet is most of the learning benefit of it.

A quiz review will be held during classtime on Fri Nov 30, and as always, you can visit office hours to ask quiz review questions, or post on Piazza.

Now that you’ve completed (2-slack-day-takers, will soon complete) the last problem set, please fill out the required Problem Set 4 reflection, which asks a few questions about how you worked on ps4. It should take only a minute to fill out, and is due by Friday, Nov 23, at 10pm.

Your project team and mentor for the group project are posted on Omnivore. The project handout has also been posted.

In Monday’s class, after we take a nanoquiz and practice team version control with Git, you will meet with your team, create your group repo, check in with your TA mentor, write a team contract, and start working on the project. The team contract is due tomorrow night, and the first project milestone is due next Wednesday after the break.

You must check in with your TA mentor tomorrow and in every class during the project. After tomorrow, there will be no more nanoquizzes. Except for a quiz review on Fri Nov 30 and Quiz 2 on Mon Dec 3, all other class time until the last day of classes will be devoted to working on the project.

We have some Constellation bug fixes that require an updated version of the Eclipse plug-in.

Before you come to class on Monday, please update Constellation:

1. Quit and re-launch Eclipse
2. In the Quick Access field at the top right of the window, enter “installation details” and pick Installation Details
3. Select Constellation in the list and click Update…
4. Accept the license, install unsigned content, and restart Eclipse to complete the update

Please visit lab over the weekend if you have trouble updating. The new version will be required for Monday’s in-class exercises.

After you wrap up ps0 (due tonight), please fill out the required Problem Set 0 reflection, which asks a few questions about how you worked on ps0. It should take only a minute to fill out, and is due by Thursday at 10pm.

Alpha grade reports and code reviews for ps0 are now available.

• To see your alpha autograde report, go to Didit, follow the link to your psets/ps0 page, and click “alpha milestone.”
• To see your code reviews, go to Caesar and click on “ps0-alpha” under “submitted assignments.”

In autograding, your submission was tested both by the public tests that were shown to you and by hidden tests. If you failed any hidden tests, you’ll see the name of the test that failed and a stack trace of where it failed. The test case inputs or code will not be revealed to you, either by Didit or by staff. The hidden tests are like bug reports from users in the field, where you get a rough idea of what the user was trying to do (the test name) and a stack trace of where the failure occurred. You need to figure out what’s wrong with your code from those clues.

You should revise ps0 for the beta deadline on Monday at 10pm. You can take slack on this deadline using Caesar, just like the alpha deadline.

Your revised version of ps0 should fix any bugs found by the hidden tests, and you must address each of your code review comments made by humans or marked #important by the Checkstyle automatic style checker, as described in the code reviewing guidelines. You can also run Checkstyle yourself.

See the problem set handout for a breakdown of how your overall ps0 grade will be calculated.

Good luck! Please ask questions on Piazza and visit lab or office hours.

Problem Set 0 code reviewing is now open. Go to Caesar to find your reviewing assignments. You’ll have 3 files to review.

Please see the Code Reviewing page for guidelines and instructions. Remember that your classmates are people like you, who are trying hard, like you. Be nice.

Code reviews are due before class on Friday.

A reminder that nanoquiz grades are posted on Omnivore shortly after the end of each class, at which point the 7 × 24-hour makeup period begins.

For example, if you plan to submit a makeup for nanoquiz 1, the deadline is tomorrow afternoon. See Nanoquiz Grading and Makeup for details.

Checkoffs and feedback on your work in class are also posted on Omnivore under that class.

For example, you can see feedback on exercises in class 3. Click “inclass-programming” and select a particular exercise to find a link to Constellation where you can see the code that was graded — for example, the partitioning exercise.

Problem Set 0 alpha is due at 10pm tonight.

Remember that if you need an extension on a problem set iteration deadline, you must request it before your current deadline passes using Caesar, as described on the General Information page.

Problem Set 0 is now available.

For help getting started with Java, Eclipse, and Git: visit lab hours 7pm to 10pm in 32-044 on Thursday night. TAs and LAs will be there to help you install and set up the tools you need for 6.031.

You must have all the tools set up and ready before class at 11am on Friday. See Part I (problems 0 to 4) of ps0.

For almost all questions, Piazza is the place to ask. Once again, welcome to 6.031!

Welcome to 6.031!

In class today you completed some reading exercises in reading 1 and took a first nanoquiz. Your grades for the reading exercises and nanoquiz are now on Omnivore.

Reading 1 and reading 2 are online.

Reading exercises are due 10pm the evening before class, so reading 1 and 2 exercises are due at 10pm tomorrow.

In class on Friday we will take a nanoquiz on reading 2. Nanoquiz grades are posted at or soon after the end of class, at which point the 7 × 24-hour makeup period begins. See nanoquiz grading and makeup for details.

If you have questions, please ask on Piazza.

Hello! 6.031 requires you to get up to speed quickly, setting up tools and learning the basics of Java. Get started here. Deadlines:

• By 10pm Thursday night, you must complete the class 1 reading and class 2 reading, including programming exercises using the 6.031 Java Tutor in Eclipse.

• By 11am Friday before class 2, you must complete all the exercises on the Getting Started page, and Part 1 of Problem Set 0. Problem Set 0 will be released tomorrow after class.

You can find these deadlines on the course calendar, plus lab hours where you can get help.

The only thing you need to do for the first class tomorrow is bring your laptop. It’s OK if it’s not set up with Java yet, and you don’t need to do reading 1 yet. If you did not receive our previous announcement, please keep reading…

You’re getting this message because you preregistered for 6.031. Welcome! A few announcements:

1. In order to join the class properly, you must fill out this signup form. Please fill it out now. 6.031 is normally oversubscribed, so you must fill out this form before the end of the first class meeting on Wed Sep 5, or else you won’t be able to take the course for credit.

2. 6.009 is a required prerequisite for this course. If you haven’t taken 6.009 (or its pilot version 6.S04), you won’t be able to take 6.031 for credit, only as a listener.

3. You will need to bring a laptop to every 6.031 class meeting, including the first meeting on Wed Sep 5. If you don’t have a laptop, IS&T can lend you one.

See you in September!
