Guilty Linking

Posted on by

I posted this to Facebook today:
‎- pre-enlightment: post reddit photos and links to people/your profile without worry. - the modern era: re-post from reddit and go out of way to credit to avoid criticism. give concise crit. to ensure others do the same. - the post-reddit reform era: get over yourself. re-post when you see fit. don’t credit reddit, because you know everyone knows where it’s from and you still thought it worth the re-post. be happy.

I’m going to formalize it a bit.

The question is: when discussing material originating from a vast and near universal trove of content, do you have to credit it’s origins? It’s meant to be the polite and correct thing to do, but when you’re crediting ‘reddit’ as opposed to a reddit account (that there’s no chance you’d remember and is very likely not to be attributable to a physical person anyway), or the originating source of the content (that, again, you aren’t going to remember even if the item in mind isn’t an unsourced picture of a kitten), is it actually worth a damn anyway? Not really. You’re crediting reddit because you’re giving the person you are interacting with credit for probably knowing about reddit too, and you’re worried that they’ll rub your unoriginality back in your face.

This is stifling to conversation. If you have something you think is worth talking about, have the damn pride to be unapologetic about it.

And don’t delude yourself. Everyone reads reddit.

CS15 Skits

Presenting… every skit filmed during Brown’s CS intro course CS15 in fall 2009.

Poster for CS15

They’ve been a while coming but I’m thrilled to finally have them online for anyone to see. The atmosphere and attitude captured in these videos is probably unique to, and more importantly absolutely ubiquitous within, CS15.

Opening Day Skit

The skit showed/acted on the first day of class. Star Trek themed (as was the course and website) in 2009. Written by the 2009 Humor TAs.

Collaboration Policy Skit

3 short filmed skits animating the course’s collaboration policy. Written by the 2009 Humor TAs.

Star-crossed References

An in class skit personifying some of the aspects of programming and the Java environment. Includes variable scope, garbage collection, references and constants. Presumably written by TAs who’ve long since graduated.

Slush Gray

In class, Snow White themed skit. Has a linked list. The skit is a long-standing CS15 feature. Presumably written by TAs who’ve long since graduated.

Othello

The skit written and preformed on film by the group of TAs responsible for the final project ‘Othello’ in which students make the board game Othello and implement a minimax based AI.

Adventure

The skit written and preformed on film by the group of TAs responsible for the final project ‘Adventure’ in which students make a 3d randomly generating objective based maze game.

Sketchy

The skit preformed on film by the group of TAs responsible for the final project ‘Sketchy’ in which students make a basic graphics editing program. Written by previous years’ TAs.

Credits

Pointer to Peach

I wrote and acted in this skit for CS4 at Brown. Cs4 is an intro level CS course for likely non-concentrators (i.e. engineers). In it, we cover a whole bunch of Matlab and a small amount of C.

The skit is about pointers and is set in the Mushroom kingdom… It’s nowhere near as hardcore as the stuff that we did for CS15 but it’s my baby, so here it is.

CS15 TAing Retrospective

Poster for CS15I TA’d the introductory Java/Object Orientated Programming CS15 this past semester. It’s a pretty interesting course as an introduction, racing people who’ve never programmed in their lives straight through inheritance and polymorphism in the first half of the semester – pretty much before using a single operator. It can get pretty intense.

My job, aside from the universal holding office hours and grading papers was to create and maintain the website, as well as to do a couple of odd jobs such as the pictured poster (which really should have had more actual information on it). That said, holding office hours and actually teaching was by far the most fun part.

Anyway, I guess this post is most directed to people considering to apply to TA the course, so I’ll try to include some useful info. For one, it’s a lot of work, a lot of time (a fair number of people end up taking only three courses while TAing this class) and you’ll be terribly underpaid. Do it because you enjoy teaching or because you want too be more involved with the Brown CS department – whatever other reason you want. It’s also a really good way to become really familiar with the course material. Aside from academic stuff, you’ll be working really closely with 15 people or so and you’ll probably get to know at least some of them really well. You’ll have ample opportunity to get to know some of the students as well.

In short, apply! It’s worth it.

CS015 Website Redesign

CS015 website ScreenshotThis semester I’m a teaching assistant for the CS015 course at Brown that I wrote about half a year ago. My main responsibility this summer has been revamping the course website. If you are reading this blog post any time before the summer of 2010, you can probably see the new layout live. In the case that I’m communicating with you over a year into the future you can see a screenshot.

My brief was to make a website that would fit with the course’s theme (Yes the course has a theme. Read the aforementioned blog post), Star Trek. I decided to base the website off the Star Trek universe’s LCARS computer systems. This was by no means an original take on making a Star Trek tribute layout – lots of fan sites have done similar things – but it is certainly recognizable.

I cherry picked other layout aspects quite liberally from different time points in the Star Trek series. The header text uses the typeface from The Original Series. LCARS itself only features in episodes and movies placed chronologically after TNG. The ship shown is the Enterprise of the 2009 Star Trek relaunch.

I ran into the CSS column issue when making the layout. The dashed line under the navigation buttons was always intended to stretch to the bottom of the layout no matter how long the content was. I originally made this work with positioniseverything’s CSS columns hack but later realized that there would be anchored links in the content presented in the layout. The anchored links caused the layout to break in Firefox, so I was forced to revert to javascripting the same effect. However the javascript I (found via google and) used to do it doesn’t work in some versions of IE. I obviously need to become proficient with a JQuery or another good javascript library.

The layout also uses conditional comments and the ie7-js script to mitigate issues with IE6, in particular the use of a png image with an alpha layer for the Enterprise in the top left.

In closing… if you are reading this and are an undergraduate at Brown, take the course this year! If you tell me you’ve read this post, I’ll give you extra special help. This statement is probably a lie.

A brief overview of CS015

The main introductory Computer Science course at Brown is CS015, an introduction to object orientated programming. It is a Java course aimed both at those with limited and those with no java and programming experience. CS017 is the equivalent course for those who have done a fair amount of programming before.

The lecturer for the course is Andy Van Dam who holds a highly esteemed position within both the Brown and the US Computer Science communities. More information about Andy is scattered across the net, but suffice to say he is a good lecturer.
