Placeholder for an idea I was playing with today (pics when I actually do it).

I disassembled my Wacom Bamboo today and broke the touch-sensitive scroll button. Woops. Being me, had I known I still would have done it (maybe more carefully). I discovered the panel inside is a decent amount smaller and thinner than the protective case (6.5" by 7 5/8"). In other words, it could be made more portable for taking to school...as well as camouflaged. The plan is to put it inside a composition book.

The other "hack" (hehe) is coming in the mail (who would have thought you couldn't buy these in stores anymore?) Remember those "magic slate" drawing tablets for kids? They're made of a tinted plastic sheet over a sheet of black plastic/wax, you write with a plastic stylus, and you lift the plastic sheet to clear the screen... Well, combine that idea with the lack of direct feedback you get from a drawing tablet (drawing on a pad while looking at the screen is hard to get used to!). They sell Wacom pens that draw in ink too but they're kind of expensive. I made a prototype drawing pad (had to order the magic slate online, so while I'm waiting on a proper one) from a sheet of colored (for candle-decorating) wax and some translucent fabric. I used it with Inkwell (Apple's handwriting-recognition technology) and to insert little doodles into my notes, and it works awesome. Yay!

Electronic Things part 1

12:14 AM Edit This 0 Comments »
Frick, this is cute.

It's a BlinkM, from here. For reference, that coin cell battery is about the size of a quarter.

The almost unnecessarily adorable breadboards are from Sparkfun.

It's not quite bright enough to illuminate the Fluff Thing. I may need a Fluff Thing 2.0 in a lighter color.

Man, no wonder I never get anything done...back to the point. I've ordered a bunch of interesting electronic bits and pieces to teach myself how it all works and work on my research project. I'm planning on documenting the learning process for mine and others' reference and/or amusement.

The setup is already incredibly well-documented and took me about 10 minutes to get working. High level overview: It's a "smart LED" that can light up in programmed sequences of colors and make it so you don't have to use up all your controller's resources on pretty LEDs. You upload the provided "communicator code" to an Arduino development board, then plug the BlinkM directly into the Arduino and connect it to your computer. This will then allow the BlinkM sequencer program to upload little color sequences to the BlinkM. It can then replay them by itself (like the pictures above). You can also use the BlinkM libraries to include color commands in Arduino sketches.

My favorite thing I brought back from a conference last year was this little plastic "ice cube" that lit up in sequences of colors. It was beautiful and rather soothing, it just fit in my hand and glowed softly. This is even better, you can make the sequences yourself. It would be a fun intro to electronics project. I'd love to incorporate it into a piece of jewelery.

It's also going to be a good prototyping tool for remotely-connected devices. My first goal once I get the network-connection bits and pieces is to be able to change the color from a web page, and then from another electronic object.

Sorry about the weird spacing, this template is pretty but kind of annoying that way. I may change it soon.
EDIT: Changed.

Camera battery charged long enough to get some pics off.
The new iPhoto is pretty nice! I'm not sure what version, the latest Leopard update as of today. It gave me a nice photo preview even before I had them off my camera, and was super speedy at uploading them.

Made this about a month ago. Now that it's been safely handed over to its recipient I can post it without ruining the surprise.




The sock is made of stretchy conductive fabric. When you place it over the sockless foot it closes a circuit located inside the guitar and the little character starts jamming to "Born to be Wild" (salvaged from a musical greeting card). I wanted to put in a little vibrating motor so it would really rock out but decided not to push my electronics luck this time.

I decided to make some Zip Flops yesterday:


25-cent zippers from a surplus fabric store + Target flip flops + duct tape.

I've been messing around with camera settings/lighting to try and get better project shots. Here's another attempt at the previously posted Merbie, I think it shows the texture a bit better. Any tips for further improvement would be appreciated.



I should get some better pictures of this little guy but I wanted to show him off:



There are magnets on his feet so he can climb fridges (presumably to get to the honey nut cheerios stored on top).

This book is wonderful, I used her template and lots of super useful tips.

Well, cluster challenge application submitted. Exciting! Lots of silly top secret-ness but I'll post more when I can.

Let's see what's on my camera.

Unless its battery is dead. Darn, more in a bit.

My ooh-crap-need-to-not-spend-money bit of the summer having reasonably passed, I'm off to order electronics for my year research project. I might or might not have posted about that already. Basically it's about creating remote communication interfaces for children and play rather than businesses, adults, and work. Googling my original title ("Tangible Interfaces for Remote Communication") of course (because they seem to do everything there) came up with an MIT project which is one of very few I've found that addresses this idea (please tell me if you know of another!). They don't seem to have actually implemented it in hardware, and that's definitely an important component of my project. I have a couple ideas right now (distributed dollhouses and shared shadows), I think I'll try prototyping both and see what comes out.

cubes! of rice!

How cute is this?

Okay, terrible picture taken with the laptop upside down over my desk, but I would have eaten them all in the time it would have taken to find my camera cable. :)

Conclusion: I messed up the rice but this little press worked perfectly anyway. It would be even better with proper sushi rice, in tiny little homemade bento boxes for school. Thanks much to my sister for the gift.

semantic space

This is kind of meta, or something:
Using an online translator to find the french word for thesaurus so I could then go find synonyms for a french word.
I got a bit distracted by the "visualize semantic space" button on the results page.

Clicking it was not particularly enlightening:



In other news my room is finally organized and I have a kickass little basket for the front of my bike. Oh the things I get done when I'm procrastinating. :)

Dark Knight Part II

3:28 AM Edit This 0 Comments »
I went to see the movie again and have to amend my previous statements a little bit. I caught a lot more, including Joker bits that I kept my eyes open for this time around. There's still some level on which he's not quite believable to me. I'm not quite sure how to explain it but I think it's that I couldn't quite make sense of his madness. Where I realized he was brilliant was that his character in a bizarre way inspires sympathy at some moments. He describes himself as reasonable even though it's all insanity and cruelty. It's like the cat sweetly telling the mouse he's doing him a favor even as he eats him. Something about his sheepish "hi" to Harvey Dent in the hospital...he's play-acting but he means it.

The scene in the building with the SWAT team had gone totally over my head the first time...what happens is that the Joker succeeds in turning everything upside down. The captives are the bad guys, the shooters are the good guys, Batman has to fight the cops to keep them from killing who they're trying to save. Brilliant.

I started crying at the /exact/ same moment after seeing it the second time (as soon as Gordon's wife starts screaming...and then harder when I find out what Batman has to become). I think filmmakers have magical buttons, someone may have to enlighten me.

P. S. I was seriously pretty sad about the Rachel thing, fictional character though she may be. Know what made me feel much better? Youtube videos setting a sequence of dramatic shots of Bruce/Harvey/Rachel to very heart-wrenching music. Seriously, people. Reminds me of this (essentially the same thing for the movie version of The Fountainhead), which I'm still laughing about. Be sure not to miss the very end of the video!

No offense meant to any of the video creators, it looks like a daunting amount of work compiling those clips and making it all match the music. They mostly prompted me to laugh at myself for taking it a bit too seriously. :) ...although I still say Ayn Rand would be spinning in her grave at the music chosen for the Domenique one (Roark thinking a woman out of his league??)

I need a category for tiny electronic gadgets.
This is a micro-SD card reader. It is freaking cute and I want one.

It will go perfectly with my future tiny laptop.

Edit: Darn it! My future tiny laptop already has a card reader. I suppose that's a good thing. :)

Halloo. Haven't posted in a while but it seemed like a good idea tonight. I tried to start another blog on crafty stuff but I can't stay on topic to save my life so I'm lumping it all back together.

First: The Dark Knight, a review for the faint of heart.

Note: SPOILER ALERT and so forth. There is crafty stuff further down, skip to that if you don't want the movie ruined.

I did some review-reading and it seems as though everyone's favorite part was how amazing the Joker was. Sucks for me because I missed most of the scenes with him in it. :) See, I don't handle jump-out-at-you or gory bits in movies well at all. And by don't handle I mean I cover my eyes and sometimes ears when I think there might be one (but of course I love plot details so when it's safe to come out I bug whoever is watching next to me to explain what happened, fair warning not to watch movies with me). So that pencil thing...I did not find out nor do I want to know where it ended up, thank you kindly. And I wish I'd missed the part about his dad but it turns out to be quite difficult to block your ears properly when sitting in the front row at an imax movie (we got there a bit late). However, it was worth it to hear Heath Ledger's freaking amazing and classic "why so serious??"...amazing and indelible.
I'm still a little torn up about the whole Rachel/Harvey/Bruce subplot. I didn't lose hope until right at the end that they'd find her in some other warehouse, slightly peeved and hungry but otherwise unharmed. I was reminded gently that we did actually see the explosion and her in the same shot. Sniff.
I thought this over for a while and I decided it wasn't that she thought less of Bruce because he didn't stand up and take the fall rather than having Harvey do it. She realized she could never really have him, whereas Harvey was genuinely hers...to the point where he broke when he lost her. Poor Batman's pretty good at loving and taking care of people without asking anything in return ("you don't have to thank me") or being loved back (letting them chase him at the end). Though in the end Rachel showed she was human when she went back on her promise to him, and I'm not so sure he could be there for someone real, he'd internalized too much of his own legend.

Completely different topic: I found an awesome yarn store in Tempe! It's called Tempe Yarn and Fiber and it's super close to where I used to live. I was excited because I'm always looking for cool non-chain crafty stores here, I miss that like crazy about the Bay Area. I don't really knit, but I like looking at pretty yarn so I went and checked it out. They have a very nice selection (from a non-expert's point of view) and the ladies who worked there were super friendly. This made me feel rather bad that I hadn't planned on buying anything until I noticed their fleece section in the back. Omigoodness they have the most beautiful colors, and having been used to working with regular wool roving I was not prepared for how amazingly soft merino is. Soooooooooooooooft oh. <3 Plus...it's not that expensive! Most of it was $2.00 an ounce, and an ounce is a lot for someone who likes making teeny things. I picked out six colors and got a half-ounce each (got a lesson when I watched the lady pull off the right amount for me: tearing off bits is much much better than cutting them). I should post the colors but I'll post something I made with them for now. The hair is this incredible purple multicolor mixture with silk in it, it absolutely needed to be mermaid hair.

Behold a sea girl and her Merbie.














ALSO someone left cran-grape juice in my fridge and he is wonderful.

This is pretty nifty--you can upload photos to flickr by sending them as email attachments, and then put them directly into a blog post without multiple upload steps. Email-centered online data management works well for me, I always have a gmail window open.

Actually about the photo: You can make neat bags from food wrappers. This instructable had the nice idea of using a clear vinyl cover. I couldn't find that, so I cut up a shower curtain and it worked pretty well. Vinyl is a bit "sticky" and it wasn't working in my sewing machine at first, so I put a piece of wax paper on top and tore it off the stitches when I was done. I haven't found the ideal lining material yet--cotton cloth isn't really thick enough, and I don't like the feel of synthetic felt.

Decisions

7:29 PM Edit This 1 Comment »
I am going to learn to make things, big and small, with fancy cutting equipment and modeling software and a soldering iron. I have been accumulating found things, taking them apart and peeking inside. I have been getting paint in my hair and burning myself with hot glue. I am taking some classes this summer. I have some experts to ask. I am daunted and excited.

Edit: Ok ok a little background. I've been spinning in circles for the last few months after I started thinking about what I was going to do after graduation. I love learning about computer science, but there are a lot of things that can be done with that, some of which I want to avoid (I don't think I can be purely a programmer/code monkey without losing my mind). And I want to incorporate making tangible things, because...I guess because it makes me happy and it's an area of "flow" and it's something I do without external motivation or needing to be "the best at" it in order to enjoy myself. There are some really cool resources (laser cutter in the design department, people who know how to use all the tools I want to learn, classes to help me get started) that I have access to while I'm in school, but I keep putting off spending time using them because I feel like there are more important academic things to do. I need to keep up with schoolwork of course, but if I'm going to do something I like when I graduate I'd best develop the skills I need for job descriptions I'm actually interested in. There.

Part of a gift: a barrette.





Also included in the gift: a matching beeswax candle (it smells wonderful, too).


A collage envelope for the birthday card.



A swatch for a geeky hat.



A giant Reese's peanut butter cup.


A silly hat in progress.


A silly hat completed.


Lots of pizza, with help from the Boy and lessons from the amazing Raven.





Wall decorations with Raven (better pictures on her blog).


A case for my nice new phone (yay Sprint for replacing it).


The beaded thing is a scavenged earring I made a long time ago. The wire to hold the beads was stolen from the spiral notebook I used in high school physics.



And ginger cookies, or what was left.


Back from SC 07

In the interest of efficiency (LOTS to catch up on, and midterms to study for), I'm going to post the email I sent my dad in lieu of a proper conference blog post.

Thanks for the advice. I had an interesting week. I talked to the UPC people and Kathy Yelick, who confirmed that I was on the right track with the code I'm working on (as in, there really isn't a very good way of dealing with runtime-determined block distribution).

There was a fantastic keynote speaker (Neil Gershenfeld from MIT's Center for Bits and Atoms) who talked generally about the mapping between information and its physical representation and specifically about some neat international Fab Lab projects. His "Internet 0" protocol is a fun concept: http://fab.cba.mit.edu/labs/lyngen/projects/iz/index.html . I think MIT is my dream grad school, given the percentage of people and projects I think are awesome that turn out to come from there...

I met a lady who does music visualization work at UNM and got a pamphlet for you on this project (networked long-distance multimedia performance): http://jackox.net/pages/gridjampages/Gridjam1.html (I was going to mail it, but the link turned out to contain the same information). They are doing some kind of computer music event at SC08, I couldn't find a link to it anywhere but I'll tell you if I hear anything else about it, could be interesting.

It wasn't as "fun" a trip as I imagined but I feel like I have a much better idea of what kind of people and jobs are in the industry, in a way that would have been difficult to experience without being there. There were more women in positions of leadership than I expected, which was encouraging. It was also nice to see people sharing information and research with each other so that efforts didn't get duplicated: for example, the presentation on cortical modeling referenced current efforts like the Blue Brain project at the EPFL, and the people writing parallel debugger plugins to Eclipse brought in the people creating trace tools for the same parallel languages.

Blue Man Group played for the closing event/party, it was pretty cool. They played covers of rock hits on instruments made of PVC pipe and sprayed paint all over the place.

I think that's about it. We didn't spend much time in Reno itself due to needing to run back and forth from the conference center and the downtown area being a little sketchy. I got a glowing plastic ice cube and a fluffy orange cube that says "Yatta Yatta!" when you throw it at walls. And...I'm pretty happy to be back. :)

Parks

1:40 AM Edit This 0 Comments »
I posted this for an ENG 102 discussion board assignment. The explanation for the last line is that the theme of the course is cities and urban spaces.

When I was small, the Park was the one my mother named "le parc au bout de la rue," or the park at the end of the street. It was four blocks west--in Berkeley geographical terms, towards the ocean, not the hills--in a residential neighborhood. For my younger sister and I, each of our frequent walks there was a rich and unique journey. I loved the ginkgo tree a block or so down and collected its golden fan-shaped leaves from the ground in the fall. My sister loved a stone deer a neighbor had in their front yard, so every trip to the park had to include ten minutes for her to sit by it and talk about Bambi, her favorite movie at the time. We watched plants grow and die and contributed to the process by picking each other bouquets, which we soon handed to my mother in order to lift the latch on the park's chain-link fence and run off to the swings. The park's real name was Totland, and we outgrew it after a few years. I brought my little brothers there much later, when I was older and babysitting, and we were soon attacked by a protective mother and had to leave. We all griped, but to be fair to her, racing toy cars with my brothers inside and my sister and I pushing as fast as we could in circles around the park was probably not conducive to a peaceful experience for the rest of the parkgoers.

It was all right, there were more parks. Upper and lower Ohlone park were a few blocks south of my father's house, past a candy and game store my little siblings always had to stop at and borrow quarters for gumballs or ogle the new Dungeons and Dragons action figures. There was a sculpture made of twisted metal to climb on, and a rope spiderweb on which we took turns being flies. If we stayed late, the playstructure area would empty and we'd be able to play "lava tag," where the pursuees could stay no longer than 10 seconds on the sand and the person who was "It" could stay no longer than 10 seconds on the structure. There was much rapid flying down slides, ducking through tunnels, and alternatingly frantic and accusatory counting. Then it would get darker and we'd hurry home, because the surrounding neighborhood was not as playful.

There was "the Rose Garden park," with a great stone slide kids could go down on pieces of cardboard--one of the last standing remnants of an increasingly safety conscious city (and country) which once had slides high enough to hurt, spinning platforms in which tiny fingers could get caught, and real wooden ladders with their associated splinters. The structures slowly became more rounded, plastic-coated, and generic. But there was always nature: the gardens on our walks through the city to the next park, the trees at Live Oak Park, the time we discovered a vine strong enough to use to swing over a creek and back.

Parks were part of growing up. "The Park" when I was in high school was right across the street from the school. It was THE lunch hang-out spot and where I went the first day I ever cut class. I lay back comfortably on the grass and protested to my friends, more habitual class-skippers, that it "wasn't that big of a deal." It was though: it was freedom to make, define, and own our decisions just as running on the grass in parks had always represented freedom and escape from the rules of a structured city and its institutions.

Yay! There's a new release of Berkeley UPC out! http://upc.lbl.gov/ Now I might finally be able to get it to work on the main cluster, it's supposedly got support for our Infiniband stack now.

But it's just hit me that I'm leaving on Monday. This is my first big opportunity to meet people in my field but I am NOT ready. Not only have I not been thinking about research nearly enough lately because of schoolwork, networking and all that is SO not my forte. Urgh.

Freaking out here!

Okay, plan: finish Lustre and SW Engineering stuff tonight so I can spend tomorrow working on UPC and coming up with questions. And goals for the conference: meet the PTP Tools and PGAS languages people (not "guys," 'cos happily both have women on the team) and learn something about neural/brain models. If I can do that, I think I can consider it a successful trip.

*musters up talking-to-people courage* I'll earn that Supercomputing swag, damn it.

I swear I am going to post interesting things and not be so bloggy soon. This was not supposed to be a LiveJournal. But I wanted to say Arizona is growing on me. I finally found a proper park on Friday! It's called Kiwanis Park and has ducks and water and trees, which is good enough for me. Also, batting cages which are more fun than I expected (basically you try to hit baseballs that are launched at you by a baseball-collecting machine). My camera ran out of charge before I could get any pictures, but I'll steal some from the Boy (who was more together about the whole checking the batteries thing) and put them up.

In other news, I think I am going to Canada over the break. It's going to be cooooold, but I am excited to do baking and crafty things with my friend Raven, who is good with that sort of thing. I miss making Christmas presents. I should not be thinking of this now, though. There are eigenvectors to find, hash tables to implement, and parallel Linux filesystems to understand first...and that is just tonight. *sigh.*

Seriously though, I'm so happy these days. I'm going to have to try harder if I want to stay properly cynical.

Ugh

I swear I am the most contrary person ever. The moment I have to do something I don't want to, but I am uber motivated to get stuff done that I don't have to do. I spent last week working on a volunteer robots project and this weekend tutoring C++ stuff I didn't know and which was harder than the assignments I did have to get done. When I did work on the projects I had to do, I did them in reverse order of urgency. This is both silly and rather obnoxious: it's a bit spoiled of me to ask for freedom in order to fulfill obligations. I'm nonetheless counting this among one of the best weeks of my life. It was the week after an absolutely insane bout of midterms and project deadlines, and I unexpectedly had time to go to office hours, to really learn rather than cram, to do work I enjoyed, and to spend time helping and working with classmates. The storm resumes in 7 minutes (the start of Monday morning), but the hiatus was wonderful.

Robots!

1:44 PM Edit This 1 Comment »
Placeholder for a proper post, but I'm really excited: my robotics curriculum team is making progress programming our robot! Yesterday we made it navigate an obstacle course of boxes and trashcans.

I'm really enjoying the process of working in a group. That combined with the fact that I'm only doing this on a volunteer basis this time (the similar project I worked on last semester I did for course credit) makes me much more productive. I'm not sure why this is, but it's good to know.
