Our Favorite Typefaces of 2008 from Typographica.
A nice quote from this article is:
Sensationalism aside, it's significant that the ever-increasing quality in type design these days - dubbed by some as the new "golden age" of type - has caused this year's list to supersede previous lists in many ways.
Golden age of type, that's cool.
tags search
Latest toy today is
M-x tags-search
I added the following to my .emacs file:
(global-set-key "\M-s" 'tags-search)
You also need to build a TAGS file, for my current work with haXe on the Orchive, I ran the following:
etags *hx
Now, to search for a tag I just need to go:
M-s
and then to repeat the tags search, I go:
M-,
Finding the definition of the tag doesn't seem to work with haXe, I'll play with it some more and will let you know if I figure it out.

I just spent 3 hours trying to track down why my ExternalInterface in Flash (actually haXe) couldn't call a simple Javascript function:
The Javascript looked like:
function test() { console.log("hello world") }
and the haXe looked like:
ExternalInterface.call("test");
Turns out it's (of course) because I was loading a local file, and wasn't running it from a web server. When I made it into a web server by putting it in my apache.conf, it worked fine.
arg. fuck. kill.

With Flash 10 on Linux, you can't change the settings with the mouse, the interface appears to freeze. To access, you need to "tabbing" and "spacing/cursoring" around.

Arduino vs. Sanguino vs. Arduino MEGA
Answer: They all rock!
I really like the Arduino. I'm going to be hacking on one tomorrow, building my electronic theremin. sness needs a day of sness, and tomorrow will be that day. Plus, I get my digikey order tomorrow, sweet sweet LED goodness.
true
Wow, fantastic post at Create Digital Music about Smule Leaf Virtual Trombone for iPhone: Multiplayer Judging Fuses Instrument, Game
"Oh, yeah, and got any doubts about the business model for open source? ChucK is a completely free, ridiculously powerful programming language for synthesis. It?s infinitely deeper than Leaf Trombone. But that power, packaged for a broad audience, can become a hit business ? and likely to be popular well beyond musicians. If that?s possible, I imagine more could be soon. Remember, too, that whatever the Apple fanboys tell you, the iPhone is not a dominant mobile platform ? nowhere close. Apple?s proprietary hardware means it isn?t really intended to be.
I hope someone working on platforms like Symbian and Google Android takes note: pack in geeky, nuclear-powered synthesis features, and people will find ways to put them to use in consumer apps that appeal to everyone. Leave them out, and you miss the boat. Or the trombone, anyway."
Ok, in my spare time, learn Google Android.

4051
My mind was just blown. I just learned about the 4051 analog multiplexer/demultiplexer. You can read tons of analog inputs with just a single analog pin on the Arduino. And it's less than a buck for surface mount and $5 for through hole mount at digikey.ca.
There is so much to learn, and it's so fun and cool!
So, I could have like 30 antennas on my electronic theremin capactive sensing device?
I was on a bike ride this weekend, and I was looking at the flowers and thinking that a sculpture that looked like lobelia would be a really neat interface to play. Cascading gardens of flowers, all making music as you walk through it.
This, combined with that video I just posted of the sparks coming out of the guys fingers on the multitouch display. How about that combined with the electronic theremin? You move in the space and the screen explodes in colours as you approach the petals and stamens, which are the antennas.
Wow. It is a very exciting time.
labial
Labial consonant
"Labials are consonants articulated either with both lips (bilabial articulation) or with the lower lip and the upper teeth (labiodental articulation). English [m] is a bilabial nasal sonorant, [b] and [p] are bilabial stops (plosives), [v] and [f] are labiodental fricatives."
"Bilabial fricatives and the bilabial approximant do not exist in standard English, but do occur in many languages. For example, the Spanish consonant spelt b or v is pronounced as a voiced bilabial approximant between vowels."
iphone blindness
Why developers obsession with the iPhone is blinding them to the potential of other iPhone markets. So true. We are in the gold-rush phase of iPhone apps. When a gold rush is already going on, don't try to catch up, instead, look for where the next gold rush will be (or the gold rush after that), and stake your claim early.
Better yet, don't chase after gold rushes.

Stepper - OSC - How to control the stepper motor using the Make Controller:
To take 1000 steps with the first stepper, send the message:
/stepper/0/step 1000
To set the first stepper to step position 10000, send the message:
/stepper/0/position 10000
Leave the argument value off to read the position of the stepper:
/stepper/0/position
To set the speed of the first stepper to step at 100ms per step, send a message like
/stepper/0/speed 100

distributed
A distributed music information system. Wow! Neat Ph.D. thesis. Here's the abstract:
Abstract:
Information management is an important part of music technologies today, covering the man- agement of public and personal collections, the construction of large editorial databases and the storage of music analysis results. The information management solutions that have emerged for these use-cases are still isolated from each other. The information one of these solutions manages does not benefit from the information another holds.
In this thesis, we develop a distributed music information system that aims at gathering music- related information held by multiple databases or applications. To this end, we use Semantic Web technologies to create a unified information environment. Web identifiers correspond to any items in the music domain: performance, artist, musical work, etc. These web identifiers have structured representations permitting sophisticated reuse by applications, and these representations can quote other web identifiers leading to more information.
We develop a formal ontology for the music domain. This ontology allows us to publish and interlink a wide range of structured music-related data on the Web. We develop an ontology evaluation methodology and use it to evaluate our music ontology. We develop a knowledge representation framework for combining structured web data and analysis tools to derive more information. We apply these different technologies to publish a large amount of pre-existing music-related datasets on the Web. We develop an algorithm to automatically relate such datasets among each other. We create automated music-related Semantic Web agents, able to aggregate musical resources, structured web data and music processing tools to derive and publish new information. Finally, we describe three of our applications using this distributed information environment. These applications deal with personal collection management, enhanced access to large audio streams available on the Web and music recommendation.

servo
Wow, hooking up a servo to the Make board looks dead simple:
Instructions for what to do.
To set the first servo to one quarter its position, send the message
/servo/0/position 256
Leave the argument value off to read the position of the servo:
/servo/0/position
To set the speed of the first servo to just under full speed, send a message like
/servo/0/speed 975
The active property corresponds to the active state of the servo. If the servo is set to be active, no other tasks will be able to write to the same I/O lines. If you're not seeing appropriate responses to your messages to a servo, check the whether it's locked by sending a message like
/servo/3/active
ROBOT
Robot drumming. Want to set up the robot drum demo this summer. Looks like there are different options. One is to use servo motors. Another, that the P.E.A.R.T. system (love the name) uses, are pneumatic devices controlled by solenoids. Another is to just use small motors.
I think I'll try the servo, since we have a Make controller here and an extra servo.
colours are nice
Another way to color your document in latex:
\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage[english]{babel}
\usepackage[centering,includeheadfoot,margin=2cm]{geometry}
\usepackage{xcolor}
\usepackage{calc,blindtext}
\setlength{\parindent}{0pt}
\begin{document}
\colorbox{blue}{\makebox[\textwidth-2\fboxsep][l]{\bfseries\color{white} Academic Achievements}}
\medskip
\blindtext
\end{document}
colorful latex
Neato way to color source code listings in Latex.
Reproduced here for your convenience:
\documentclass[12pt]{article}
\usepackage{listings,color}
\begin{document}
\newcommand{\Hilight}{\makebox[0pt][l]{\color{cyan}\rule[-4pt]{0.65\linewidth}{14pt}}}
\begin{lstlisting}[escapechar=\%]
start:$
%\Hilight%mov r1, xF0 -- Reset ptr value$
mov r2, x00 -- Reset total value$
\end{lstlisting}
\end{document}
