How not to write a questionnaire question

Monday, October 13th, 2008

I was checking out the latest Rasmussen reports and saw this advert on their site:

Talk about a leading question.  Note to pollsters: color coded answer buttons are helpful and not biased at all.

ZOMG!!1 I’m on Valleywag!

Monday, September 29th, 2008

Well, a picture of my painting is on tech-”press-release regurgitation machine”-crunch.com-alternative valleywag, anyway.  Here’s a screen cap, in case you don’t see it when you go there:

Give some love with your credit card. No purchase necessary.

Some folks from my alma matter have a startup non-profit company trying to make extremely low-cost incubators to save newborns in developing countries.  Typical incubators cost thousands of dollars, but theirs costs only $25.  

Their project is one of the top 25 on the American Express member’s project, and with your vote, they could win and earn $1.5 million in funding.  They’re up against serious competition and need lots of votes. 

So, if you have an american express (u.s. cardholders only), click on this link:

http://www.membersproject.com/project/view/AGAYRZ

and login to vote for “Embrace”.  There is NO donation required.  Amex will donate $1.5 millon to the project with the most votes.

Deadline is september 29th.

Flows to Ocean

Here’s a picture I took from my kitchen window.  Note the model Angelino emptying his bladder into the storm drain right outside my house.

This is in Santa Monica, a year after I’d moved into the place.  That’s his SUV back there.  He just drove around the corner, pulled over on a no-park zone, and unzipped his trousers.

Back when I first moved to Venice, I saw someone through my front window hike up her skirt and take a dump on the grassy area in front of my apartment.

Naked Computers

Tuesday, September 9th, 2008

Think about your current career.  Now, think back to an object that you loved that influenced your decision to follow that path.  For me it was a Commodore 64 that an uncle owned.  Anytime my uncle was away I’d sneak in some programming time, making the machine blink its borders, or animate a smily face across the screen, eventually freaking out my mom by writing a program that wrote “This is GOD speaking!” across the screen while blaring a crazy synthesized seemingly infinitely ascending tone.  Now think about this: can today’s computers awaken that curiosity and sense of awe that eventually lead you to a career in computers or are they now so opaque that, unless someone purposefully installs a programming environment, they’re unlikely to engage with the computer in a way that leads you to experiment with it?

I started thinking about this when I was reading a review of Falling for Science: Objects in Mind, a book that asks a similar question: what beloved object began your love for science?  The book consists of 51 essays, including some from senior scientists, answering that question.  You can probably guess some of the objects, like LEGOs and computers, for example.  But some objects are a little more surprising, like chocolate meringue pie and My Little Pony.   

My initial reaction was a nostalgic feeling that, no, today’s computers don’t lend themselves to that type of engagement, they’re opaque, not transparent .. get it? naked … nevermind.  Sure, today’s computers come pre-installed with software that lets you make movies, music, and write documents; programs that lets you create stuff and, an environment with tool for creative activities, but activities unrelated to computation.  I think of today’s machines with tons of craplets and compare it to my first PC, which had BASIC and the source for a little game about a monkey that hurled bananas; basically, stuff that let you play with the raw bits of the machine.   Yeah, the end product oftentimes was a video game, or some multimedia thing, but I had to translate from computer code to sounds, graphics, or algorithms.  That’s the sort of stuff that led me to my interests in computability theory, communication, and HCI.  My social and physical interactions with computers have had tremendous influence on what I’ve done, even down to the subject of my college essay.  I think that’s why the mac feels like such a great environment; because it comes with all the media stuff installed AND with programming and scripting languages that let you muck with the machine. 

I really like Turkle’s concluding remark that “at a time when science education is in crisis, giving science its best chance means guiding children to objects they can love”.  

Don Knuth Speed Paint

Sorry Prof. Knuth!!

Sometimes PS doesn’t realize the pen is connected to the computer.  When this happens, I can’t use pen pressure to handle opacity, or to handle thickness.  So I basically end up with this =s  To fix it, I have to go to the pen’s control panel, make a change, change it back to the original setting, then reopen PS.  I’m too lazy tonight so that’s what you get.  15 mins.

I needed to make his head taller.  He’s a genius, after all.

I tweet therefore I am. new iteration

Wednesday, August 27th, 2008

UPDATE: My portfolio site has moved to http://robertxcadena.com/

Ok, i’m calling it quits on this one for now:

i think i’m also renaming it to Being and Tweet, as a play on heidegger’s being and time. This disintegration of the self feels more like heidegger than descartes. so there you are.

i may work on it some more since i want the colors to be more saturated, and maybe i’ll work on the thumbnails, but my eyes are hurtin’

Command line compile Arduino on Windows

Saturday, August 2nd, 2008

Here’s how to compile your arduino programs using the command line in windows xp.  I took the Makefile from the Arduino forum, but modified it because it didn’t work for me, probably due to my using Arduino 0011.

1. Make sure you have Arduino 0011 installed and that you can upload and run the blinking LED sample program.

2. You need make.  Install cygwin.  I have gnu make 3.78.1 installed.

3. Download this Makefile.

4. Create a directory somewhere and a file called “main.pde”.  Use the blinking LED program from the Getting Started section of the Arduino website.

5. Put the Makefile there

6. Modify the Makefile to suit your project.  Instructions are in the Makefile

7. Run make, it should build the stuff

8. Run “make upload” and your program should be uploaded to the board.  You can have auto-reset with Diecimila, but you have to modify avrdude.conf, which is in INSTALL_DIR/hardware/tools/avr/etc/avrdude.conf.  The Makefile has instructions for how to modify avrdude.conf

Happy physical computing.
