5 Under 25; Tonight

Thu Mar 22 08:31:56 EDT 2012

Here is an email from Fundies II alum Mike Amirault about tonight’s 5 Under 25 event. Hope you can make it.

Hello Prof. Van Horn,

My name is Mike Amirault and I am a member of the Student Alumni Association (SAA) and also am in the class of 2013 here in CCIS. I was in your Fundies 2 class way back in the spring of 2009 and also have tutored Fundies 1 for you the following year. I wanted to take the opportunity to inform you of an upcoming networking series that the Student Alumni Association and the Office of Alumni Relations hosts that will be beneficial for your students.

The program is called 5 Under 25, and it is a panel series that gives current students a glimpse of where their education and experiences at Northeastern can take them. The 5 panelists are all recent CCIS graduates who are under 25 years old. The program gives students the opportunity to ask questions and hear about co-op experiences, class schedules, student involvement, job searches and their emerging careers.

This month, the Student Alumni Association will be hosting 5 Under 25 for the College of Computer & Information Science on Thursday, March 22nd at 6:30pm in the Alumni Center (716 Columbus Ave, 6th floor, across from Squashbusters). There will be free pizza, drinks and dessert served.

The panel will include :

Brian Correia – Technology Support Specialist

Dan Gonyea – Software Development Engineer

Lauren Siegert – Product Software Engineer

Phil Kelly - Systems Administrator

Jeff Cumplido - TBA

I would greatly appreciate it if you could let your CCIS students know of this event so they may have the opportunity to hear alumni success stories and make key contacts. If you have any questions about the program, please contact me at amirault.m at husky.neu.edu.

Best,

Mike

What: 5 Under 25, College of Computer & Information Sciences Where: Alumni Center, 6th floor, 716 Columbus Ave (across from Squash Busters) When: Thursday, March 22nd at 6:30pm Who: All students interested in networking with successful young alumni and learning more information about the CCIS classes, student groups, co-ops, careers and more.

Marathon code

Mon Feb 13 11:19:36 EST 2012

Here is the code we’ve developed so far for the Boston Marathon.

Here are a couple things worth trying to do:

• Sort the list of runners in alphabetic order.

• Compare the code for all and any to andmap and ormap from last semester.

• Try to develop the Java analogue of filter.

• More challenging: develop winner which produces the runner with the best time. (What should you do if there are no runners?)

• Develop a variation on winner that produces the runner with the lowest bib number.

Question on homehork

Thu Feb 2 08:07:50 EST 2012

Here is a question we got on the current homework:

I am currently working on completing the directionTo method in the second problem of the homework, but was not sure what the method should return if the two points are the same. Should I assume that they’re always different points, or should it return "Same Position", or maybe even throw an exception? I figured I would ask since the problem didn’t really explain that particular scenario and I just wanted to make sure that I implemented the method properly.

Good question.

When the customer does not specify something it is Ok for the programmer to design a reasonable solution and document the choices he/she has made.

I think returning the String "Same Position" sounds reasonable, especially considering that as of this homework we know nothing about exceptions, and that we really do not want the program to crash, just because for a short while during our trip we take a break for lunch and stay in the same place.

Small revisions to Assignment 2, SVN guide, Code style

Fri Jan 20 15:41:20 EST 2012

We’ve made some small adjustments to assignment 2, so be sure to read the latest version. (You should reload the page in your browser if you’ve visited it recently.)

Jonathan Schuster has put together a nice guide on using Subversion that includes instructions for Windows, Macs, and Linux machines. It also tells you how to organize your code and how to set up Eclipse to work with the repository.

We’ve also added a note on proper code style that you should use for all the code you write in this class.

Programming is like Cooking

Wed Jan 11 11:05:34 EST 2012

Here’s a recent NYTimes article (There’s the Wrong Way and Jacques Pépin’s Way) about the chef Jacques Pépin, author of La Technique. There are many fruitful analogies between programming and cooking; one of which is that Pépin’s "technique" is very much like our design recipe. The goal of Fundamentals I and II is to instill the essential technique of great programmers, and to borrow Pépin’s words, "Once you learn the technique, then can be a creative programmer; a great programmer is first a tehnician." And there’s only one way to become a master of technique: "you have to repeat, repeat, repeat, repeat until it becomes part of yourself."
