The three-wheeled strollers were sold in different color fabric combinations with a metal black and silver frame including: green seat and canopy. There is a plastic red toy steering wheel, ignition key and orange shift lever mounted on a yellow base attached to the stroller tray.

If your stroller wheels have a gray triangle located on the rim at the valve stem then your stroller wheels are not included in this recall. Consumers should immediately stop using the product and contact the company to receive free replacement wheels. Consumers should use a manual bicycle pump to inflate stroller tires to a maximum of 30 p.

Do not use gas station air pumps to inflate stroller tires. Kolcraft and the CPSC have received 39 reports of inner tube ruptures causing the wheel rim to fracture and fly off as a projectile. Of these, 18 included reports of injury, with 14 occurring while filling the tire with air by adult caregivers. Two of the reports included property damage. The U. CPSC is committed to protecting consumers and families from products that pose a fire, electrical, chemical or mechanical hazard.

CPSC's work to help ensure the safety of consumer products - such as toys, cribs, power tools, cigarette lighters and household chemicals -— contributed to a decline in the rate of deaths and injuries associated with consumer products over the past 40 years.

He is also very patient in class, answering questions in detail. Hu is a super approachable guy, except during exams! The assignments and labs are all do-able, though the penalties for small compilation errors on assignments are harsh. The midterm was pretty long and it had a mistake on it and I and many others got wrecked. The final was significantly easier and the scaling was huge. There is a lot of material in the course though, and the questions on exams definitely require some thinking.

However, if you are okay with mathematical proofs and work consistently you should be okay after scaling. Proof of program correctness: Slightly different than mathematical proof, make sure to fully understand the conditions for a program to be correct. I only realized towards the end of the course, that this requires you to really read and understand the code fully.

Evaluating time complexity of given algorithm: Generally easy, but curve-balls can be thrown. Try breaking it down or stepping through the code. Really important course for interviews, along with Felt like I improved a lot of reading code, and Dr. Hu was pretty entertaining. Alan Hu Dr.

Note: Office hours are your time.

You needn't make an appointment or wait outside the door. Come right in and take part! If you want to meet privately with one of us, however, please let us know. Labs are required and marked. You may also work on labs at home, get help during scheduled Office Hours, or post questions on the course discussion boards.

You should aim to finish your work and get it marked within the 2 hour session. However, if necessary, you may continue to work on it over the following week, as long as you have it completed no later than the beginning of your next lab session.

Getting your work marked if you are absent: If you must miss your regular Lab session, an extension for any work that was due until your next scheduled session normally one week can likely be arranged.

You cannot get your work marked in a session later in the week; it can only be marked in your regular session. Extensions of more than one session are not available. Getting help with the current lab: You can get help with your work on the current lab at Office Hours, by posting questions on the course discussion boards, or possibly at one of the remaining lab sessions See the course Calendar at Schedule to determine which Lab sessions remain, and what Office Hours are being held before your next lab session.

If you want to attend one of the remaining Lab sessions, then you can, as long as there is space in that session. Email your request to the Lead TA at the above address.

Your final course mark will be based roughly on the following breakdown. The staff reserves the right to change this scheme but do not anticipate using that right. Updated on March 26 To give you more incentive to study for the final, we're making the following change to the marking scheme, which provides a great opportunity to improve your final grade! So in the new marking scheme:. Most electronic communication should go to Piazza. You are expected to read the Announcements daily!

Personal questions or those that might violate academic conduct standards if posted should go to your Instructor or to the individual staff member you wish to contact see the home page for email addresses. There will be roughly three programming projects and three written assignments during the term.

Programming Environment: You may use any development environment you wish, but all programming projects must compile and run correctly on the Linux ugrad. See the computing and programming guideline pages for tips. Submission: Programming projects will submitted with the " handin " tool. Check handin's acknowledgment of your submission to see if your submission proceeded correctly.

Written assignments will be submitted in the hand-in box for CPSC location will be announced. Schedule: Programming projects will normally be due at 9PM on the due date, and written assignments at 5PM.

Late Policy: Late work will receive no creditbut we can be flexible if you contact us promptly, well before the due date. So, tell us if you're having trouble! Collaboration: See the academic conduct guidelines. Scheduling: Dates for the exams are available on the Schedule webpage.

Recall date:.Now that I've finished with all my 2nd year CPSC courses, I guess it's a good idea to write down my review before I forget about it, especially since I'm now on a co-op work position.

CPSC is your introduction to some lower-level, operating system and software architecture basics. Essentially, you'll be spending roughly 2 months learning to program in assembly language, specifically referred to as SM in this course; since I can't find any references to it outside of the course, I'm going to assume that this is specific to CPSC but it's conceptually similar to programming in assembly language on another architecture, e. Intel x Then you'll spend the remaining month learning about topics like threading, schedulers, concurrency, and virtual memory.

The purpose of learning assembly is for you to learn how higher-level languages like C and Java get translated into simple, concise instructions that computers can understand and execute, e.

In fact, in many of the labs, you will end up translating short snippets of code from C into assembly and vice versa Java will be thrown into the mix later. The latter half of the course is all about lower-level operating systems related material, i. You'll learn about all the considerations you must make when designing programs that run in parallel which is an increasingly relevant issue now that CPUs are becoming multi-core behemothse.

The course itself goes at a pretty brisk pace and builds upon stuff that you've previously learned within each half of the courseso keeping up is pretty important. Debugging also plays a very important role, probably more so than in previous CPSC courses. It's easy to make errors while programming in assembly, and not so easy to find them, so do yourself a favour and learn early on to use that Simple Machine program you're provided with.

In my opinion, the course tends to get progressively more and more difficult for the first half of the course, up to the point where you'll be handling polymorphism with assemblyand the labs in the second half of the course can be extremely frustrating at times. You do not have to go to your scheduled lab sessions and to be honest I never went to my labs after the first one ; labs are all handed in online via the 'handin' command-line program.

Speaking of handin, you'll also gain a bit of practical Linux experience in this course, i. For many, this is probably one of their first encounters with Linux; a friend of mine ended up complaining that handing in his first lab seemed harder than actually doing the lab itself.

My prof Dr. Tamara Munzner generally explained concepts well and was an effective prof overall for and she even brought cookies in-class occasionally, yum! Workload is manageable, but again, do make sure you keep up.

Textbooks: Discrete Mathematics with Applications 4th ed. The course name pretty much says it all: this is going to be a course where you'll learn tons about various data structures, and some of the algorithms that you can build given those data structures.

If you think back to the material you covered in CPSCyou'll remember that there was a strong emphasis on designing data structures that meet your needs HtDDD ; if not done properly, writing functions that operate on that data HtDF would often be futile and frustrating. You'll begin the course with review of material that partially overlaps with CPSCincluding sets and functions, proofs, induction, iteration vs recursion, loop invariants if you hoped that proofs and induction were a thing of the past after you finishedsorry :P.

The rest of the course is going to explore lots of different data structures and the algorithms that build upon them: linked lists, priority queues and heaps, various sorting algorithms mergesort, insertion sort, quicksort, heapsort, including implementation examples and analysis of complexityhashing and implementation details, e. The above is not a conclusive list The written assignments are roughly as challenging as the assignments from CPSC ; on the other hand, the programming assignments are likely harder than programming assignments done in past courses I'd say somewhat harder than the Android end-of-term project for CPSC I think I averaged hours per assignment in total.

I don't really have any specific advice for the projects, besides the generic "don't leave it till the last minute", but I think most of you have figured that out by now.

Oh, and as with CPSCtest compile your code on the department Linux machines before handing in your code not just on your own machineunless you want to risk hitting a compile error and getting a big fat zero.

Unlikeyou do have to go to lab sections since they're marked in-lab by your TAs, but technically you could just go every other week since labs are due the week after they're assigned.

Written assignments handed in-class, projects handed in via the command-line "handin" program like the labsand labs handed in by showing your TAs your work and answering questions to make sure you understand the concepts. Will Evans is a decent prof. It's pretty clear that he knows the material he's teaching well, but unfortunately he can be quite soft spoken at times As I noted in the "nutshell" section above, there's luckily a web page of recorded lectures for CPSCso if you've slept through a lecture, you can just rewatch a video of the lecture in your own spare time.
