 Welcome to Computer Science E1. My name is David Mail and this is lecture 12 Pictionary. You are about to be traded for some exams for candy. So please hand your exam to the nearest teaching fellow in the aisle. From them you will also receive a scrap of paper. Please make sure you have a scrap of paper given to you by the teaching fellows. These are going to be our secret ballots for tonight. I'm going to start the candy down here. There's plenty for everyone. We have three different types of lollipops from Tootsie to Blowpops to Jolly Rancher tonight. So as you know, at the courses end, every one of you will walk away. Those of you tuning in from afar via distance education as well will receive a I survived Computer Science E1 mouse pad designed by one of you. It is tonight that we choose the winner of that design. Those of you who have tuned in from afar have voted via email. So we would take those votes into account. What we'll do tonight is a secret ballot where you're about to vote for your top three choices and then we will run a very high tech algorithm offline to determine the winner of this year's mouse pad. Again, at final lecture, you'll walk away with your very own mouse pad. We have exhibits A through N tonight. These are all of the mouse pads that were submitted for the recent multimedia problem set that were to specification. There were a few sadly that weren't quite of the right resolution, right color depth and so forth. So we only have put on for vote the mouse pads that we know will print nicely on an actual mouse pad. So with that said, why don't I zoom us through A through N, maybe make a note to yourself which one or ones you like best and then we'll do one more pass through them so you can solidify your votes and then we will proceed to tonight's lecture. This is exhibit A. So make a note to yourself if you like this one that you might want to make this one of your top three votes. Exhibit A. This is exhibit B. This is exhibit B. This is exhibit C. If you can't read it back, it says I survived E1 dot dot dot but now I have to figure out how to get out of this mess. Next we have exhibit D. I told you I'd survive CSCI E1. That is exhibit D. Exhibit E. In small print up top, I survived computer science E1. That is exhibit E. Exhibit F is this one. I survived computer science E1 with my face pasted onto the little guy in the middle. This is exhibit F. And exhibit G, I survived computer science E1 and it didn't affect my sanity at all. This is exhibit G, I think. Yes. Exhibit H. I survived E1. Did you? Sort of a nice amalgam of photos from the course. Oh, Dan, you lost at Jeopardy. Sorry, question mark is among the quotes in there. That was exhibit H. Here is exhibit I. I survived E1 but now my brain looks like this. Next is exhibit J. I survived computer science E1. For those of you tuning in from home, this was clearly the required theme of these mouse pads. Exhibit K. I survived computer science E1 in 2006 specifically. This exhibit K. Exhibit L. Knowledge now available by podcast. And on his button I survived computer science E1. That's exhibit L. Exhibit M. I survived computer science E1. That is exhibit M. And finally exhibit N. I survived CSCI E1. Now, had I best zoomed through them all again or would you just like to see certain ones again? Need a refresher or are you good to go? Great. Great for audience participation. All right, so is that enough information to put it to a vote or do you need to see them again? Yes? No? All right, so quick refresher. I'm going to do it much faster this time. That's A. That's B. That's C. This is, that's E. Now we'll go back to D. And now we have F. And now we have G. Mind you, this is where folks tuning in by a podcaster quickly fast forwarding. Next we have H. That was G. This is H. Next we have I. Next we have J. Next we have K. Next we have L. Next we have M. And next we have N. So on your scrap of paper, you don't need to put your name, but go ahead and put something like the number one, and then the letter of your first choice, and number two, the letter of your second choice, and the number three, and the letter of your third choice, and so forth. If any of these are your designs, you are more than welcome to vote for your design. That is perfectly legitimate. And we will tally these answers off hand, these votes. So when you're all done, go ahead and pass these scraps to the edges of the aisle. If there's any you need to see individually, just shout it out now, and I'll pull it up again. But otherwise, we're just about ready to dive in. Sure, a little scrolling. This is harder than some of the exam questions it seems. You know, it's always nice when the exam starts with that chuckle that we heard from some of you, but we didn't really hear somebody chuckles by the end of it, so don't quite know what that means. And as a voiceover here, we will grade these exams tomorrow night, so you should see your grades online by Friday, and we will return them after the break or at this Saturday's workshop or section if you opt to attend that. And in fact, let me take a moment to have one of the team members come up and pitch this weekend's and tonight's section events. This week's section is going to be about Scratch. You'll have a chance to work on creating your own projects with that. And this weekend is going to be about JavaScript, enhancing websites with JavaScript. So you are free to use that for your final project if you'd like. And since it's the holiday season, we're going to use the occasion to show you how to make some JavaScript-based greeting cards. All right, excellent. Now comes the awkward part. I need four teaching fellows to come on and sit down here. And this is going to be, we'll call them the TFs team tonight, and the rest of you get to be on the students team tonight. We won't waste time with team names tonight, but in here's the awkward part. What I need is for all of you to come down to the first three rows. You're not going to appear on film, most of you, but we do need you within range of these microphones. So grab your gear if you wouldn't mind. I know, humorous, we gave you candy. That should make this easier. And come on down to the first three rows and cluster yourselves, if possible, to this side. You're probably about to meet someone new. Say hello to the person next to you. I don't want to touch them. Come on down. What's going on in the back of the lecture hall here is the students are now coming down to the first three rows. Go ahead and squeeze on in. All right. So as you settle down, we have here the game of Pictionary. Now for this to work well, we actually do need participation. None of you are by any means obligated to partake in front of the cameras, but the teaching fellows are, so they'll be on camera. I'll be on camera, and we need one or more of these brave students to actually be up here at the board. That there, say, is the fun part. And I'll say this, let's just assume all of us stink at Pictionary, because that's probably going to be your fear coming up to this board, being challenged to draw something. And my God, not only are we watching, but those folks tuning in from home. But that's okay. The idea is that this is meant to be fun. We've got a beautiful board here. We've got a quick draw. The categories from which we will draw tonight's challenges will be precisely the lectures from fall 2006. Hardware, the internet, multimedia, security, website development, and programming. The way we will do this is we will have a huge stopwatch up here. You will have a minute on each round that will make a cute little sound when it's expired. What we will do is have multiple rounds of this, whereby we'll take someone to draw from the TFs team, someone to draw from the students team. Those two will very nervously perhaps come up to the board and will say, go, they'll have 60 seconds to draw whatever object, place, person, thing, entity happens to be that I tell them from our list of potential questions here and what they will have, though, the opportunity to choose the category. And if your team shouts out the correct answer for what is being drawn, however abstractly on the board, that team will get a point and control of the category for the next round. And we hope the students among you will relieve each other of the pressure of being up here alone and will fill in when someone needs to be tagged out from drawing. With that said, any questions? All right, in a coin toss before lecture, the students won the toss, which means we now need our first drawing volunteer. And why don't we get this out of the way and just say, we know it's going to be Don. So Don, I think your name was just selected. If you don't mind, come on up, we have a piece of chalk for you. The teaching fellows, meanwhile, have chosen whom to represent them at the board first. Okay, and the only caveat here is that for your answer from the audience to qualify, you got to shout it out, not only for me to hear, but for our several microphones up front here. Since Don has bravely volunteered to be up here first, you get your choices, categories, hardware, the internet, multimedia, security, website development, and programming. Hardware. Hardware. So I'm going to choose a question from hardware, and I'm going to show it to both Don and Ray. They will then have 60 seconds to draw without writing, obviously, the name of what they've been shown. And we'll use this as the rule. You can draw anything you want on the board, except any letters or symbols from, say, a keyboard. So you can't, for instance, a la, win, lose, or draw, start writing down the word, but you can do some gestures, just nothing verbal at the audience. All right, with that said, the first thing to be drawn will be this in the category of hardware. This item in the category of hardware. And to be clear, there's no raising of hands here. There's no rules here other than shout it out as fast as you can, and if you get it right, we will increment your counter under the current score, which at present is zero to zero. What are the TS prepared for this, though? They have, like, a whole system. Oh, well, that is true. They have the luxury of knowing what we were about to do, but it requires just as much savvy on their part as yours to guess these things. My disclaimer, I didn't even know how to play Pictionary until this minute. Okay. So I didn't get around to telling all of the teaching fellows what we're doing tonight. Yes, I owe biomeds. Ah, just letters, we'll say, for now, since you've already found a hole in my logic. So yes, that is okay. What she said is okay, because we're probably thinking the same thing. With that said, here comes our super-duper clock. We put one minute on the board, and again, shout it out. When you know what it is, the category is hardware. Fight. Binary. Binary, I heard. Thus, David screwed up already by prohibiting use of symbols and letters and choosing one full of just symbols. But we'll give it to them. Five seconds. That's pretty good. That one, yep, the black ones. Alright, let's keep these guys up here a little longer and go put another minute on the clock. Dawn's team, the student's got one here, so I'm going to increment your score and Dawn, you are in control of the category. What would you like? Probably. I heard programming first, so we'll go to programming. Dawn and Ray, your next drawing item is going to be this one in the programming category. This item here on the left. Alright, then you have 60 seconds on the clock, and you may begin. Branch. Alright, three seconds. Yes, let's hear it for the students. For the students. Alright, what category would you all like next? I heard internet first, so I am going to choose something slightly harder this time. And here we go. Dawn, this item is going to be this. And the category of internet. Ray, the item is this. And the internet. And now, I'm going to get you this time. You have a minute on the board. Go. What page? HTML. Tag. Tag. Tag. Header. Scratch. Dark type. Box. Link. URL. URL. Link. HTTP. Oh! I don't know what either of those two are. Great. Okay. But that's okay. Browser window. Browser window. Okay, the TFs are on the board, thanks to Dan. So we now have two to one. Dan is, and the TFs are in control. What category would you guys like? I heard secure, wait a minute. Securities. Oh, they show security too. Alright. Question for Dawn, and as soon as you get bored, you get the pick. Pick. Pick one from the audience. Okay. Alright, your question now is going to be, your question now is going to be this one here, in the category of security. Category of security. Category of security. Alright. 60 seconds. Go. Cookies. Hacker? Black hat. White hat. White hat? Hacker. Spyware. Oh, heard it here. Spyware from the teaching fellows. I like how you both have a big hat on the old school's five versus five. Alright, we have a tie, two to two. We're going to give it to the teaching fellows, since they guessed right. What category would you like? Multimedia. Multimedia, for one point, and let me suggest when you draw, since I didn't say before, try as best you can to stand to the side, so that the teammates can see what you're drawing. That's why they got it this time. That's all. Alright, Multimedia. Your question. I can see what you're drawing. Great. Alright. Your question is going to be this one in Multimedia. Multimedia. You have 60 seconds on the board, and go. I don't know why you didn't just do this. Multimedia. Next one. Same category. Multimedia. No points have changed hands. Multimedia. 60 seconds on the clock, and you may go. I'm going to try to come to her defense here. Whoops, whoops, whoops. Yeah, that's... I think he... She's done well. Three, two, three, two, three. Good job. Anyone come forward? Yeah, come on down. What's your name again? John. John has come to her relief. The chalk changes hands. We're going to give John control the category for bravely volunteering. That's okay. What category would you like? The internet. So here we go for the internet. Go with this one for internet. Internet. Okay. Internet is the category. And go. Okay, Bracey, whatever you do. It's Ty. Alright. Dawn and John are carrying the team. What would you guys like, students? Security, I heard. Alright, security. Genia has come up now. We are going to go. Alright, that's good, that's good. We're going to go with this for security. The category is security. 60 seconds on the board and go. Oh, take it, hack it. It's supposed to be an axe, I see. Perhaps we should have chosen topics that weren't just on the exam. Alright, what would you guys like next? Programming. I heard programming. So programming. Ooh, let's see. And we are going to this time go with, in the programming category, this guy. Programming is the category. Alright, you have 60 seconds on the clock and go. Java, Java, Java. Java! This is a harder question this time. The students are leading five to three students. What would you like? Programming. Programming, Eugenia and John still at the board. Caps. Money. Think about this one. Go. Lines of code. List. Pretty printing. Tags. Paragraphs. If then Boolean. Caps dating style sheets. Pretty printing. Smiling rakes. Smiling face. Paragraph. Unhappy. Sad. Mad. Branch. Boolean. Experiment. Experiment. Table. Swords have moving. What do we want for students? I know most of the students are looking over here now. Condition. Stuck in the body. Script. Folium. Text. 20 seconds. Looks like the whole jargon sheet. Probably. Nested. Boo. I thought I might have heard something here. From a female voice. Achieve it. CSF. Value. In a buttery jargon. Before that, I have a question. In piece 3. Dynamic. What was the answer? Out. Out. Out. For what I could tell that was the only word from the jargon sheets that you didn't call out. Okay. So let's stay in the programming category. Give these guys one more round. So David now has one point. Let's go ahead with. Let's go ahead with. That side of the board. Let her swipe. It's getting hard to read on the camera. Yeah. Thank you. Cheat too. Cheat. Cheat. Cheat. We want to call that problem. All right. So in the next category, still programming, we have this. The guess. Categories programming. All right. We have 60 seconds on the clock and go. Sit. Climb. Programmer. Programmer. Programmer. Where did I hear it first? Dan. Dan. Oh right. Over here. Oh really? That's what you're doing. We said, all right. Wait, wait, wait. Programmer. Programmer. Programmer. I totally called. All right. So we'll give it to the students. What is this? We could go to the video page. All right. All right. Does anyone want to relieve John up here? He's done three or so points already. Come on. Anyone at all? Not yet? All right. Let's give him more of a lead. Eric. I heard Eric. It comes on up. We're going to be competed against Chris here. Eric, what category would you like? The website? No. Nice. A new category. Website development for a point. Your. Your question. Your question is going. All right. Easy. Is going to be. I'm going to embarrass myself by choosing some of these because they're so easy. All right. Let's go with this one. There we go. Website development. Website development. It's hard. I know. Website development. Go. Website developer. Move to the side. Stick. Catch him. Students pull ahead to sevens to three. All right. Let's give you a Chris choice of category since she's up here. First time. What category would you like for your team, Chris? Multimedia. Multimedia is the next category. All right. And your question is going to be. Your question is going to be this one in multimedia. Multimedia. Multimedia. Go. Music. Scratch. Napster. Napster. This is just embarrassing. Eight to three. Eight to three. That's okay. I think they would have gotten it soon. Eric, what would you like this time? Hardware. All right. I heard hardware. We're going to start putting 30 seconds on the clock. Hardware. In that category, your question is going to be this one in hardware. In hardware. All right. One minute on the clock and go. Oh, well, next. Processor. Network. Slayer. Land. Server. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Client. Push атom. Attempt. Reach the network. Oh, infrastructure. Wouter. Cool. IP address. Moutter. Printer. AnneXx. Macadress. Boost. IP address. IP address. Person. Fios. Sentiment. Fios. Heard it. All right. Very good. Our good angle Chris Gotti for us with Egenia here. Poma? No, no, no. All right, so the TS have narrowed the gap, it's now eight to four. Chris you're in control, what category would you like? Security, I heard security, security, and we're gonna go with this one for security. Security, minute, oh no we're gonna go, let's do this, 30 seconds are on the clock and go. Packet sleeping, website. Proxies for work. Oh, efficient. Packet is no, um, spam. Adware, adware for a point, excellent. Let's do one more round with these guys up here and I'm gonna change the rules here since clearly telling you the category makes it a little too easy just to guess everything, though that was not a guess I'm sure. So no long, just like in Pictionary, every category now will be in all play. So with that said, your next question which means it can come from any category is going to be this one. This is in any category that we've seen there on the board. Only these two know the category now. 30 seconds, go. Coding. File share. Nice. We don't even need the category. Nicely done. Alright, students go up 9 to 5, 9 to 5, so Eric we're gonna give chalk to someone else it sounds. Anyone at all? Oh, what's your name again? Jonathan. Jonathan, so Jonathan V. Ray, we're gonna give Jonathan no choice actually because we just changed the rules didn't we? And we're going to choose this as our topic. And we're gonna choose... Oh, here we go. This is your topic. Can you read it okay? Wait, which one? The bold face right there. Okay. Bold face word there. Alright, 30 seconds on the clock, go. Friends. Interfriend. Interfriend. Oh, keep friends. Compression. Lossy compression. Move. Both words were said, but you didn't say them together. Interfriend. Interfriend. Very good. That was like 10 times. Very nice. I think that was coming too. Alright. Number five, it's a solid lead. Let's make this a two-point question. Ray, what category? No, I am such an idiot. Alright, there is no category. There is no category. So your question is going to be... Your question is going to be this. In any category. Any category. Alright, 30 seconds are on the clock and go. Wireless network. WPA. WPA. 802.B. Wireless speed. Wireless access. Wireless network. Hence Ray's A. These guys are still up here. I'm going to choose another one here. We're going to go with this one. Jonathan, drawing this now. Just feel free to erase if you want. Alright, any category. Can no letters from the keyboard? Nobody saw that. Alright, 30 seconds on the clock and go. Body. Body ticks. Each time. I should have heard it here first. Alright, so I'm sorry, the teaching fellows got it. Six to ten. Time for a few more questions. It wasn't. One or two points now. Alright, sorry. Not very good at this game. Alright, and the next question from any category is going to be this one for Jonathan and Ray. Any old category for Jonathan and Ray. Alright, 30 seconds are on the clock and go. Compression. Bitmap. Pixel. DPI. Resolution. Desk DPI. JPEG. BNP file. Browser. The words have been said. Bitmap compression. It was bitmap graphics. I know the judge might get some stares here but we're going to go by the rules. Bitmap graphic. Dan said bitmap image which was close. We got one more for these two guys before we change drawers. Jonathan. Drawers. Alright. No one got that one. We got Jonathan, Ray. No pressure here. Let's make this a three-pointer. What is this? Last time. One point. No control of the audience here. One point. Go. 30 seconds. Clotty. Tree. Tent. Network. Spider. Leg. A worm. Lord for Jonathan. Last chance to go up against Dan. Come on down. Can we make this a three-pointer? Yes? Alright. Heather V Dan. This is a three-pointer which means because of the way we're rewriting the rules the TFs can catch up with this one. So your question is going to be your question is going to be this one for three points in any old category. Three points. Heather V Dan. You have 30 seconds on the clock and go. Stream. Streaming. We did. We did. Dan V Heather. And of course to say tie we'll have a runoff for one more question. Your question is going to be your question is going to be your question is going to be your question is going to be this in any category for six points. No pressure. So either Dan can tie this or Heather can win this. You have 30 seconds on the clock. Little big round of applause for these guys. You said it to Jenia. You said it to Jenia. Bus. Bus. Alright. No question because that puts the TFs up to 13. So Dan V Heather one last time we're going to let the audience choose the category. All categories. All categories. It's an all play. And your question for the game. So for one point for the game for the game for the game. It's for the game. 30 seconds and go. XHTML X button. X box. Cross over cable. Cross over cable. Dramatic care. Hold on. In five seconds the game will end. Ray just for drama. Shout it out one last time. Cross over cable. Have a wonderful break. We will see you in a couple of weeks.
