New stuff I did

It seems like even though this year at Penn is just getting going, I've already done a bunch of new things that I've never done before. Therefore I'm going to start a record (in approximately chronological order lol) and update it as I go along.

• August - purchased a bunch of appliances for my room which I didn't have last year - toaster ($12), microwave ($35 I think?), coffee maker (like $20). They are all turning out to be useful so far. The toaster is surprisingly popular :)
• August - purchased a set of pots/pans, which came with a bonus collection of spices, with rack, which I'll probably never use...
• August something - really practiced bass clarinet. It's awesome, but hard to "get" the sound above the break; really hard to get good tone on that. And it needs SO much air!
• Again, towards the end of summer - I wanted some tea, and Dad drinks it all the time, so I asked him to make a cup for me. He gave me chai, and I ended up really liking it. (Ok, so it's not my first time ever drinking tea, but my first time trying chai.) I got a box of chai to bring to Penn.
  
• 8/31 - watched Anchorman with Rebecca, Becca, Eamonn, and Ben. Part of an initiative to see movies that apparently everybody except me has seen. Opinion: it's not my kind of humor, definitely. I guess some moments were funny, but it just often feels ridiculously overdone. (Obviously this is the point, though..)
• 9/3 - Saw Dan for the first time this year and was totally shocked by his new much shorter haircut (also not parted in the middle anymore) and switch from glasses to contacts (!!!!!)
• 9/3 - Purchased food from food carts/trucks. Last year John got me a sausage-egg-and-cheese from Bui's but this was the first time I ever bought anything myself. Dan and I went to Hemo's for lunch; I got a grilled chicken pita. For dinner Simone, Tatini and I tried to go to Magic Carpet but it was already gone, so we went to The Real Le Anh (Le Anh is across the street haha), and I got cashew chicken. Two discoveries: it's really good, and really cheap!!
• 9/3 - I guess a couple of FNAR courses I've taken have been cross-listed as grad courses, but CIS 460 (Computer Graphics) is definitely the first CSE/CIS course I've taken that's cross-listed. It was a bit intimidating, realizing all these quiet students were probably graduates... hence the invention of the DMD Undergraduate Row :D
• 9/4 - First class where I don't have cell phone service (I think). This is because it's CIS 262 down in the basement of Skirkanich (kinda like a dungeon hahaha). Probably all for the best - I should seriously pay attention in that class.
• 9/4 - First ever class I'm taking on databases. woooot
• 9/4 - First class in which I might be the only student who's not a music major. A little intimidating. =/
• 9/5 - Cooked a dinner dish by myself! It was meatloaf, and it was good! yayyy
• 9/5 - Attended Rodin bingo, and actually won a round! I got a gift card to Gap. Yay shopping!!
• 9/6(?) - FREE LAUNDRY!!!!! Most unfortunately I had to go up 2 floors to the 14th floor since the machines on my floor were all occupied.
• 9/7 - Discovered I did not make wind ensemble on bass clarinet... first year at Penn that I won't be in it, but that also means I can go to the music program's Third Thursdays now :)
• 9/7 - Played DDR (via Stepmania) with my own pad in my room at school. (I actually had the pad with me last year in Stouffer but never took time to play.)
• 9/8 - Taking a class in Linux :D
• 9/8 - Taking a class being taught entirely (as far as I can tell) by a computer science student in my own grade - the aforementioned Linux half-credit class. I feel like I should be feeling extremely inferior or something, but I don't. Zach's friendly and a good lecturer and definitely knows a LOT. Which is awesome :) . I think he was even in my 260 class haha...
• 9/8 - First job at Penn: mentor for CIS 110. We had our first meeting and it was a friendly gathering. We even talked about who had which lab shifts and office hours, as I was rushing out for band, lol.
• 9/9 - Met Danny's sister Laura - she's awesome! The three of us went to Cosi for dinner :)
• 9/9 - Salsa lesson at the Penn Latin and Ballroom Dance info session. It was sooo embarrassing but SO MUCH FUN!!! I decided I was definitely going to the lessons and began trying to convince friends to come...
• 9/9 - Tried iscribble for the first time, with John. I actually plugged in my mouse (finally) cuz there's no way I was gonna draw with the touchpad.
• 9/10 - First lab as a 110 mentor, with Ryan as the TA. I have to get there late, cuz it starts at 2:30 but I have 460 till 3. Luckily I made it in time for introductions and I even answered a bunch of questions which made me useful, yay!
• 9/11 - Played ping pong with Danny and Carlin in the lower level of Harrison - good times!!
• 9/12 (technically) - went to Allegro's around 1am with Carlin and Danny and had .. chicken and broccoli pizza? Or something like that. It was good, lol.
• 9/13 (or late night 9/12) - Installed Linux (Ubuntu) on a virtual machine on my computer!! Now I really want to install it "for real" (on a partition on my hard drive)
• 9/13 - Went out to dinner with Menghan and ate Thai food! I had drunken noodles hahah but it was really good AND I have leftovers!
• 9/13 - Went to Penn PM karaoke event with Erica, held on the Stouffer patio. Thanks to Erica I actually went up to sing; we did Beat It together. Michael Jackson's voice is way too high for my range (whatever limited range I might have), so next time I'll definitely be picking something else :P
• 9/13 - Uploaded pictures using Google's Picasa. It's got captions and some kind of tagging of people and reordering, and I was even able to include videos (though I had to actually download Picasa for that, rather than just using the web service). However, it seems that unless you upload through the Picasa client program, you can only upload 5 photos at a time..? This seems kinda ridiculous, especially considering how on Facebook you can upload a bunch all at once - I think it's a Java application actually.
• 9/14 - Played clarinet at church for the 10am Mass. This went pretty well, considering I got the music last minute. I had to skip a couple things, but overall it sounded good!! (And this is despite my clarinet not playing very easily, which is a fluctuating thing.)
• 9/14 - Right after Mass I went to the "hospitality" thing - like "Doughnut Sunday" at home, but on a much smaller scale.
• 9/14 - PLBD social lessons!!! Salsa and tango. SOOO MUCH FUN hahaha I cannot wait to go back :D (this really probably deserves a full post to itself)
• 9/14 - Lost my band pants (somehow by mixing them up with a pile of laundry on top of a machine) -> realized this, hours later -> panicked while trying to do my Graceland assignment for music 150 -> emailed Neil, who included my plea in his email to the floor -> received my pants from someone who found them mixed among his laundry by accident -> I've never been so glad to see those pants hahaha
• 9/15 - Ate a cookie and a brownie from Cosi (at cis 1xx grading system learning session); they were so good that I took another cookie for the way out haha.
• 9/15 - Used Dreamweaver in the Rodin computer lab - the version was old enough that it was still Macromedia... (2002 or 03-ish? I wonder why it's not updated.)
• probably September - Web design (9am-12 on Tues/Thurs) finished early enough for Grace and I to go to Wawa before 262. I got Wawa coffee for the first time and it is AMAZING. (Also much cheaper than Starbucks...I should keep this in mind and shift some of my coffee habits to Wawa...)
• 11/24 - arrived late to a clarinet social gathering which included watching Zoolander. I've never seen it before since it's not the type of movie I would typically like. (I usually don't find that kind of humor funny.) For some reason I was intrigued by it though, and although I didn't plan on staying long, I ended up interested enough in the movie that I stayed for the whole rest of it, to find out how it ended. I didn't love it and still thought it was pretty silly, but liked it enough to surprise myself.
  

geek-out moment :D

i'm up at 4:42am and for once it's not just because of facebook or other things (seriously i don't even know what i'm doing when i stay up late on the computer...). for my linux class the first thing we have to do is get access to linux somehow, either eniac or install on our own computers. well it'd be even more awesome if i could repartition my hard drive and actually install linux, but i think i'll save that for later. (i did actually spend a bunch of hours one time researching this possibility but was a bit nervous about actually doing such things to my hard drive.) so instead i'm using virtualbox to run a virtual machine on my laptop and install ubuntu on it. so basically i dl'd ubuntu as an iso image and mounted it into the virtual machine's cd-rom drive, then "installed" linux to a virtual hard drive on my machine (the "host" machine..gotta have my terminology down :P ). while it was installing i even did some online banking, downloaded music (REO Speedwagon... John mentioned some lyrics to me and I listened to one song on playlist.com and decided to download some and check it out), and started renewing my ruckus licenses. woot for multitasking!

after it finished installing, i mounted the iso for the "guest additions" thing from virtual box (which adds a bunch of ease-of-use features, like increased virtual box screen resolution and options for "capturing" the mouse on the guest vs. the host) and ran my first ever linux installation via commands in the terminal!!! i wish i'd taken a screenshot, however.... i did save it as a text file (gedit is the text editor) ANDDD since i have the guest additions installed, i can now copy and paste to and from the guest and host!! so here it is!!

Double Take

--> first and second takes on my classes this semester.

Note: This is an exercise in speed blogging, to be performed as practice in writing something of value but without taking forever. We'll see if this works.

Ok so here are my impressions of my classes from the first and second sessions of each (except for the 399, since it's a half credit and only meets Mondays). Btw these are in order of occurrence of the first session of each class.

CIS 460: Computer Graphics
[first class] Well we all gathered in Wu & Chen (aka Levine 101) where I took CIS 110, haha... There were a bunch of grad students, which was minorly intimidating for a sec, but made sense after I remembered it's cross-listed as CIS 560 and probably they're CGGT (Computer Graphics and Game Technology) students. Grace and I instated the "DMD Undergraduate Row" - I can't remember exactly but I know Ted, John, Carlin, Brynn, Nirav, and Ryan (a sophomore who was in 277 with us) are all in the class. The class began with Nirav asking if the slides could be printed in black and white and Dr. Badler explaining how the trio of himself, PowerPoint, and the printer do not get along. Then Dr. Badler introduced the field of computer graphics by describing a number of its applications. The class felt really comfortable and familiar, obviously because it's the class which 277 was specifically designed to precede (and taught by the same professor). As it's my only class on Wednesdays, I had a pretty good first day of class! :P
[second class] This turned out to be hilarious for a good 20 minutes or so when PowerPoint was being strange and YouTube was just not cooperating for Dr. Badler, and then neither was the DVD at first - and all he wanted to do was show a couple of videos! At one point, for the DVD, we had video but no sound, and then we had sound but no video! I was crying laughing...which I felt kinda bad about... The rest of lecture was pretty chill; I followed along in my $25 coursepack of the lecture slide printouts, just purchased from the SEAS copy center. We're definitely gonna be reviewing some material from 277, but for sure that can't hurt! (And it'll probably move fast.) So my outlook is lectures will be cool... Homeworks? Not sure how intense they'll be, yet. Definitely expecting to be coding a lotttt. We don't have lab, which is a little nervewracking, because clearly they won't be going over OpenGL and C++ stuff with us anymore. (We are supposed to remember it all from 277. lol..) We do, however, have Skiz as a TA, so that should be awesome. :D Maybe I will go to some office hours for once...

FNAR 234: Web Design
[first class] First off, the instructor seems good - he's cool but he knows his stuff. He comes from the design side, which I like, because I think that's the side I need more instruction/work on. (Also, he and the TA are friends and make a good pair. Kinda like Jeff and Sunita...hahaha.) From a code standpoint, I'll be relearning some html, and probably some css, though I definitely know there's a LOT I can still learn re: css. More importantly I hope I learn design and usability, which if the book he asked us to get and the first/ongoing project are any indication, it should be a focus. We are doing the html/css in Dreamweaver, so that should be interesting, and I might feel a little cheap not coding it all straight by hand. Also he keeps calling html and css "programming languages", which to me doesn't seem quite right, because I've always thought that programming languages DO something, whereas straight html and css don't perform any kind of actions on their own. Still...a good first impression, and I'm hoping not too stressful. Also Grace is in the class so that's cool.
[second class] We went over web terminology, complete with examples. So, yay I learned what some things mean! I don't care if it's elementary, because that might be where I am with some of this stuff. Then he demoed how to set up a blog and then we basically had an hour to start the blogging assignment. :) If not previously evident, I'll mention now that I like the TA, Erin, as well.

CIS 262: Automata, Computability, and Complexity
Ok this course deserves a precursor. Ever since at least the end of last year, when I really tried reading the course title during registration, I was pretty petrified of this class. The fact that Evan used to say he hated it while he took it (along with a few glances at his notebook) only added to this sentiment...
[first class] On the bright side Dan will be suffering through this class alongside me, as well as Grace, Jay, Carlin, John, and..? Anyway at the beginning of class Dan informed me that "automata" is pronounced with the emphasis on the second syllable; hence I'd been saying it wrong every time I listed my classes for someone and explained that I was scared of this one. Oh well. We are in Berger Auditorium in the Skirkanich basement, which is chilly and Dan and I both have no service. (This bothers Dan more than it does me.) The professor has something of an accent though not too horrible, I just have to listen a little harder. We spent like 10 minutes on syllabus stuff and then launched immediately into notes. Thus far I've followed what's going on, but I don't think I can trust that as an indicator that the rest of the class won't get plenty harder...
[second class] Well actually we have a "recitation" for this class - only one section of it, so basically it's an hour long and taught by the professor rather than a TA. It's my only class in DRL this semester - I was so close to not being there at all! At least A8 is a nicer room, despite its prior association as my Math 114 room haha. Anyway, we started going over proofs by induction, which is not a topic I enjoy but nonetheless familiar from 260.
[third class] This was the second lecture. It was pretty much more of the same, and luckily I am still understanding like 95-100% of the notes. People are already falling asleep in that class though, haha. It's probably gonna be a long semester. I miss Benjamin C. Pierce (260 prof) cuz...he was more engaging and pretty much all-around awesome.

CIS 330: Design Principles of Info Systems
(I basically translate this course title into "Databases".)
[first class] Well Dan and I get to walk from 262 and chill in this class too, so that's cool... Class began with the course webpage mysteriously being inaccessible, and other oddities. But once we got into the lecture, I'm glad it's starting pretty much from the bottom-up level of databases. I'm not exactly sure how the course is going to progress, either content-wise (she kept emphasizing that we're not gonna come out of it as Oracle programmer whizzes) or difficulty-and-effort-wise (we may not have even learned enough to do the first homework yet).
[second class] This time we all introduced ourselves and holy crap, Chin, our 121 TA who managed our final project, is in the class!! Nirav and I were laughing haha... (Am I really up to par enough to be in the same class as Chin??) At least I found that most people had only a bit of database experience so I should be okay. We continued through the lecture and it all seems reasonable so far. I'm really hoping I learn a lot through this class. I'm so eager to collect knowledge and ability in something really different from everything I know so far.

Music 150: Introduction to Global Music
Talk about a change from computer science...
[first class] Well, the class is almost entirely music majors - maybe one person who's not (as she wasn't even there at the second lecture), and then me, an attempting minor. So that's a little intimidating, because they have a lot of background knowledge to draw on and they know how to write and speak about music. Well the professor is very into it all, integrating both organized writing and stream of consciousness writing with listening to the music and especially exposing ourselves to music with which we're uncomfortable. There is to be lots of discussion and class interaction, etc. So I was pretty scared the first day, since I thought this was gonna be like jazz history where I listened to lectures and caught up on textbook reading, wrote one simple paper at the end and a couple of jazz performance reviews...yeah. Not this class. It's gonna be pretty intense, and I'll have to dredge up writing skills I haven't touched since freshman first semester. So much for an easy class...
[second class] We shared our "exotic" music selections and I found that I could participate in this collaborative discussion without sounding like a total idiot. I probably accomplished that though when I did not have much of a way to explain why my Praful song was "exotic". Oh well, hopefully that moment can be forgotten. For some reason I felt slightly less scared of the impending syllabus (though probably not because she kept saying we would be nervous but it would turn out okay) - with the major exception of this partner-project thing, which I'll worry about until I see how the partner issue pans out (ugh). I'll also have to see how well I can get myself going with these writing assignments.

CIS 399: Special Topics: Linux/Unix in the 21st Century
[first and only class so far] Jean Griffin, who teaches 110, is listed as the instructor for this, so I guess maybe "officially" Zachary Goldberg is a TA, but as of the first day, he appears to be essentially teaching the course. I mean, his name is on the slides so I assume he made them. He's a good speaker - already more naturally engaging (or I thought so anyway) than Ryan, who taught our Python course. (Don't worry, I like Ryan in his own way.) The funny part is he's in my grade (so Dan told me, and once we got to class, I recognized him, and I think he was even in 260 with us haha), but that's ok cuz supposedly he knows this stuff really well, and I don't think that's an exaggeration. He's starting with the very basics of Linux, which is awesome because that's what I need! I'm really excited for this class, cuz like databases, I'm gonna learn something that I know almost nothing about beforehand...except Linux is just kinda cooler than databases from the start. :P Also I noticed I am one of like three total girls in the class; all the rest is guys. Oh well haha.


The semester is gonna be crazy, I bet. 262 alone could drown me in painful work. I am hoping databases and Linux won't be bad, and hopefully interesting!! Web design should be good too, maybe my only semi-respite from the rest. I can see 460 being really intense, because if 277 was really intense and it was just the "intro" to this class, then we all must be really in for it. And music, well, it'll be its own kind of crazy, I'm afraid. I really did think I was pretty much done with writing. I guess it's a good skill to prune every once in awhile, at least (hahaha). Very different from last semester and even last year - no psych, music is back, digging 260-type of thinking out for 262, and totally ground-level new subjects. At the very least, it will be interesting. Here we goooo! (This good mood I've been in recently must be in part because I have done almost no work yet...possibly due to the fact I am lacking some key textbooks... I will need to beginning devoting time and energy to work-mode soon.)


Results: speed blogging? Kind of failed. Partly by distraction of thinking of Jeff and Sunita, which led to emailing Jeff, and also by a bit of chatting with Carlin. I'll try harder in the future.

Freshman year at Penn ... v.3

This (and similar future posts) are inspired by a Facebook note written by Keelan... hope he doesn't mind me stealing the idea :)

The following is a list of things that happened in my freshman year of college, in a fairly random order, as I think of them:

• first roommate I met - running into Erica in the Rodin lobby when I was checking in
• my dad helping Tatini and her parents install her mirror on her room door
• wearing my beach towel to the NSO toga party
• "sketchy toga party guys" and Jen (me), Lee (Simone), Natasha (Tatini), Monica Sanchez (Marcela) and...crap what was Ben's ?? [thanks to Simone for remembering Marcela's code name haha]
  
• fire drills at 4am and 7am, everyone trudging out to the stairway in pajamas
• the wind tunnel
• baking Nick's bday cake (buying stuff at Fresh Grocer, borrowing the heart-shaped pan, spelling the words on it with Cheerios)
• running from DDF to wind ensemble (only a half hour in between) on Thursday nights
• slipping on Locust Walk in the rain in my clogs and flip flops
• keeping the list of funny quotes ("Penn Quotes")
• discovering when I first arrived at Penn that I'd been missing out on Facebook (because EVERYBODY was talking about it), and hence getting it immediately when I set up my computer haha
• listening to Mae all the time on purevolume.com (before Ruckus)
  
• had a crush on a guy I'd started talking to over the summer; decided later on that it was probably superficial O:-)
• freaking out in my first CSE110 recitation because the TA TOTALLY confused me when he tried to explain something like x = x + 5 in Java, telling Eric Fisher about it, and ending up switching into his recitation
• getting breakfast at Commons with Dan every Thursday morning (because I had class from 9:30 to 1:30 I think?), then walking to our math104 recitation
• learning what spooning is, and discovering I'd already done it haha
• getting hot chocolate with Rebecca after band field rehearsals on our way back to the high rises...
• ...and eventually transferring to mochas, then lattes, and declaring myself a Starbucks coffee person (after years of thinking I don't like coffee!)
• falling asleep ALL THE TIME in the first row in music theory!
• eating chocolate covered espresso beans and absolutely cracking up over whatever with Rebecca instead of studying for something
• first time I ever slept in the same bed with a guy
• exchanging "stories" all the time online with Henri
• room switching in Rodin 108 halfway through the year
• over spring break, a 260 problem defeated both me and my dad for hours one night; then as I was falling asleep I figured it out, and later led Dan through the steps to figure it out :)
• doing math104 homework with Dan during his ITA lab hours on Wednesday nights (the night before it was due in recitation, of course)
• spending hours playing Stepmania with Evan one night instead of doing our homework (my first time playing it, and hence the beginning of my addiction haha)
• shopping for Freshman Formal attire at King of Prussia with Erica, Tatini, and John (and the craziness of the buses to get there and back!)
• going to Chris's Jazz Cafe with Rebecca (for my jazz history class) and with my jazz writing seminar class
• after playing Sweet Child o' Mine all the time in Penn Band, I finally listened to the real song and liked it so much that I listened to it over and over till Erica came in and asked me what was going on! haha
• eating dinner at Commons with everyone: Erica, Tatini, and Simone; Matt (our GA); sometimes Ben and Chris from across the hall
• when the washing machine left my clothes soaking wet so that after 2 runs through the dryer, they still had to be hung up on the clothes rack for awhile to dry
• late-night bus trip with John to the art store Pearl on South Street cuz I needed gray paper last minute for drawing class
• Keelan wearing someone's high heels at the Penn Band Semiformal (hilarious!!)
• staying up till about 5:15am finishing my jazz history final paper on Praful (latest I'd stayed up up to that point, I think)
  
• Rodin ski trip to Camelback with John: discovering maybe I'm only good enough to ski double green circles (apparently those Montage black diamonds were nothing much, haha), falling once and losing a ski, falling again via crashing into someone and getting impressive bruises on both knees, getting run over by a lift (hahaha), the bus breaking down (or did it hit another vehicle?) when we were almost back... good times :D
• discovering that rainboots are fashionable (never would have guessed!)
• fell madly in "like" just after it was too late (as usual), spent a couple months or so pining away reading over saved online conversations and listening to supposedly emo music, finally got angry enough to let go, and slowly redeveloped a friendship
• experienced my first kiss
• nudged two friends into converting to DMD (my major)
• savored the glory of having only one class on Fridays (first semester), and the icing on the cake: it was not till 1pm!
• played Outdoor Overture AGAIN - after having the solo part in high school concert band, I found out what the third part is like thanks to the wind ensemble...
• came home for fall break and visited my high school marching band, where I was smothered by hugs from my clarinets - it felt so amazing :)
• carved the beginning of my downhill curve in calculus: math 104 was okay, but math 114 started getting harder... (maybe it was the professor's approach to teaching, but still.) I started thinking maybe I don't like math so much anymore?
  
• confused my shoulder for my elbow one day in said math 114 class (hahahahha Grace...)
• began experiencing the great ups and downs of being in a relationship
• wrote perhaps the most inefficient program I've written so far in my life: every time I wanted to write a line to a file, I opened/closed a FileWriter. Let me tell you, it was SLOW. And absolutely hilarious - after I figured out what was going on, hahaha.
• woke up 15 minutes before my jazz history class, put on the first clothes I found, walked as fast as I could to Fisher Bennett, and climbed 4 flights of stairs to get to the room - and still arrived while people were moseying on in with their coffee/breakfast
• got caught in pouring rain after a band field rehearsal... walked back to Platt with Jenn and Keelan and got drenched since my umbrella was back in Platt, then had to stand dripping in the lobby while my forgotten Penn Card was fetched for me from downstairs. Returned to my room and hung up my pants to dry for like 3 days lol.
• sat between Dan and Evan while the two of them doodled and wrote little notes back and forth on my 260 notebook - so much for paying attention in class that day, hahaha
• making the "ADD in DMD" Facebook group with Michelle...during DDF...haha
• watching Nirav and Luke play guitar just inside the quad entrance till like 3am
  
• ..more to come?
