Higher-order shell - How UNIX commands in scripts are like higher-order commands in functional languages like Haskell.

By the way, I was volunteering at ICFP 2008 (International Conference in Functional Programming) last week, and got to meet many of the luminaries in functional programming. Some smart people there, let me tell you.


I'm going to be presenting a talk at a workshop coming up:

The Many Faces of Multimedia Semantics
It used to be called Robust Multimedia Learning in Broad Domains.

Navaratri One: Kali

Begins tonight. Om Kali Namaha!


I've just switched over to haxe 2.0. It seemed to be quite an easy switch, not much seemed to break, and now I have default arguments in the variable list, which makes porting AS3.0 code so much easier.

Android media API

Recording audio with Android:

Start recording:

recorder = new MediaRecorder();
ContentValues values = new ContentValues(3);

values.put(MediaStore.MediaColumns.TITLE, SOME_NAME_HERE);
values.put(MediaStore.MediaColumns.TIMESTAMP, System.currentTimeMillis());
values.put(MediaStore.MediaColumns.MIME_TYPE, recorder.getMimeContentType());

ContentResolver contentResolver = new ContentResolver();

Uri base = MediaStore.Audio.INTERNAL_CONTENT_URI;
Uri newUri = contentResolver.insert(base, values);

if (newUri == null) {
// need to handle exception here - we were not able to create a new
// content entry

String path = contentResolver.getDataFilePath(newUri);

// could use setPreviewDisplay() to display a preview to suitable View here



Stop recording

I get very bored of Times New Roman in Latex, so to switch things up to Helvetica, just add the following after \documentclass:

Much better.

Near Future Laboratory Top 15 Criteria That Define Interactive or New Media Art

The Near Future Laboratory Top-15 Criteria for New or Interactive Media Art are...

15. It doesn't work

14. It doesn't work because you couldn't get a hold of a 220-to-110 volt converter/110-to-220 volt converter/PAL-to-NTSC/NTSC-to-PAL scan converter/serial-to-usb adapter/"dongle" of any sort..and the town you're in is simply not the kind of place that has/cares about such things

13. Your audience looks under/behind your table/pedestal/false wall/drop ceiling or follows wires to find out "where the camera is"

12. Someone either on their blog or across the room is prattling on about the shifting relations between producers and consumers..and mentions your project

11. Your audience "interacts" by clapping/hooting/making bird calls/flapping their arms like a duck or waving their arms wildly while standing in front of a wall onto which is projected squiggly lines

10. Your audience asks amongst themselves, "how does it work?"

9. The exhibition curators insist that you spend hours standing by your own wall text so that you can explain to attendees "how it works"

8. It's just like using your own normal, human, perfectly good eyeballs, only the resolution sucks and the colors are really lousy..plus the heat from the CPU fan is blowing on your forehead which makes you really uncomfortable and schvitz-y

7. Someone in your audience wearing a Crumpler bag, slinging a fancy digital SLR and/or standing with their arms folded smugly says, "Yeah..yeah, I could've done that too..c'mon dude..some Perlin Noise? And Processing/Ruby-on-Rails/AJAX/Blue LEDs/MaxMSP/An Infrared Camera/Lots of Free Time/etc.? Pfft..It's so easy..."

6. Someone in your audience, maybe the same guy with the Crumpler bag and digital SLR excitedly says, "Oh, dude. That should totally be a Facebook app!"

5. It's called a "project" and not a "piece of art"

4. You saw the "project" years ago...and here it is again...now with multi-touch interaction and other fancy digital bells and Web 2.0-y whistles

3. Your audience cups their hands over various proturbances/orifices at or nearby your project attempting to confuse/interact with the camera/sensor/laser beam, even if it uses no such technology

2. There's a noticeable preponderance of smoothly shifting red, green and blue lighting effects

1. People wonder if it wasn't all really done in Photoshop, anyway

3 Bonus Criteria!

0. There are instructions on how to experience the damn thing

-1. You can't "collect" or buy it. Heck, if you did, you'd need to get AppleCare or hire an IT guy in the bargain

-2. Crumpler guy says, "Oh, I thought of that already.."

If you are running a Python interpreter and you change a source file on disk, you need to reload it by doing:


You can also reload all modules with:

for mod in sys.modules.values():

But this is probably the wrong thing to do. Read Reloading Python modules for more info.

javascript tree

A really nice little tree view widget in Javascript. Such a better API than the YUI TreeView widget. I love the YUI, but some of their javascript APIs pretty suck, this one is so nice because you mark up your tree with HTML lists.

Sequence - provides a unified api for access to sequential data types, like Strings, Arrays, Files, IOs, and Enumerations. Each sequence encapsulates some data and a current position within it. Some operations apply to data at (or relative to) the position, others are independant of position. The api contains operations for moving the position, reading and writing data (with or without moving the position) forward or backward from the current position or anywhere, scanning for patterns (like StringScanner, but it works in Files too, among others), and saving a position that will remain valid even after data is deleted or inserted elsewhere within the sequence.
