mouse
On my sweet beautiful laptop that I make music with, I'm running Windows 7. Being a total Linux nerd, I need my Linux, so I both dual-boot and, more often, use the amazing VirtualBox to host an Ubuntu client. With this, I can run a single session for a long time, weeks in real life time, and often plug in an external mouse. When I do this, it works great, but then later when I don't have my mouse plugged in, I can't use the shortcut of both mouse buttons on the touchpad to do a paste operation.
To fix this, go:
sudo rmmod psmouse ; sudo modprobe psmouse
This will remove your mouse driver and resintall it.

hack
Things I learned about organizing a hack day - Wow, that is a lot bigger than I was planning for our mini-music hack day in Victoria.
massive rails find
a = Recording.find :all, :joins => "INNER JOIN annotations ON annotations.recording_id = recordings.id", :select => "record\
ings.*, count(annotations.id) annotations_count", :group => "annotations.recording_id HAVING annotations_count > 1"

rails ftw
in this case, ftw does not mean "for the win"
If you get the error:
ArgumentError (A copy of XX has been removed from the module tree but is still active!):
Check your environments/development.rb for config.cache_classes and try
setting it to true:
config.cache_classes = true #false
static
Static, Shared Dynamic and Loadable Linux Libraries
Interesting, I recently learned that your PATH is searched for .so libraries in Linux. "." in PATH means exactly that.
outlier-FM
Outlier-FM - Grand Prize at the recent Boston Music Hack Day
About
OUTLIER FM is a weekend's attempt to utilize advanced technology to search for beauty and surprise in even the most overproduced of popular music. We hope such exceptional moments can be found in OUTLIER's enigmatic soundscapes of reconstituted timbre and rhythmic intersection. It is called OUTLIER because the moments selected for further attention are precisely those moments that exist outside of a song's constructed and statistical conventions.
At its core, then, OUTLIER is about doing away with the package through which a song is carefully prepared for our consumption and rebuilding it from its smallest perceptual units into a strangely unpredictable, minimal techno investigation of sonic wonderment. Working from sophisticated audio analysis provided by The Echo Nest's Public API, OUTLIER provides in addition to audio tracks and radio [ed: SOON] a visual interface for humans and computers alike to become virtuous in high-level sound extraction and resynthesis from pre-recorded audio tracks.

base
If you get the error:
/var/lib/python-support/python2.6/MySQLdb/__init__.py:34: DeprecationWarning: the sets module is deprecated
from sets import ImmutableSet
Then check out this page. Which says to:
To get rid of this error and use the more efficient built-in set
type, do the following in the __init__.py file that was reported:
* comment line 34: from sets import ImmutableSet
* add after that line: ImmutableSet = frozenset
* comment line 41 in the original file: from sets import BaseSet
* add after that line: BaseSet = set
Like this the built-in types will be used anytime a BaseSet or an ImmutableSet is referenced.
and
In converters.py :
comment line 37 : from sets import BaseSet, Set
add after that line: BaseSet = set
add after that line: Set = frozenset

Google Wave Scrollbars - I'm not a fan of them. Interesting idea, but they are way too laggy and don't work well on longer waves.

xmouse #2
Just got bitten by the CTRL+SHIFT+NUMLOCK on Linux:
oh my goodness, I just learned that you can move the mouse in X11 by pressing
CTRL + SHIFT + NUMLOCK
And then navigate with the arrowkeys. Press CTRL + SHIFT + NUMLOCK to get out of this mode.

creator plunderphonics
Here's an intermediate step along the way of my Music 507 project, which is to do a Plunderphonics of a song. I chose one of my favorite songs Creator, by Santigold. For this, I used Ableton Live and a lot of Follow Actions.
Some Pd ---> Max/MSP conversions (maybe with errors)
tabread4~ ---> play~, (also groove~, wave~ or similar things)
tabosc4~ ---> wave~ (probably)
tabwrite~ ---> record~
delread~ ---> tapin~
delwrite~ ---> tapout~
hip~ ---> see the HP filter thread (also biquad~ and filtercoeff~, and many others)
samphold~ ---> sah~ (works differently in Max, I prefer the Pd style)
wrap~ ---> don't remember
noisi~ ---> does not exist in Pd
graph ---> ?

Do you ever make a web site or program and then spend hours just playing with it, pleased with your creation?
Oh yes, with The Orchive, I'm totally obsessed. Love. The. Orchive.

He received his Ph.D. in Biology from the University of California at Santa Cruz, where he studied killer whales at the north end of Vancouver Island under the late Ken Norris as a National Science Foundation Graduate Fellow. His research has been diverse, involving both captive and wild marine mammals. It has addressed behavior, communication, population dynamics, genetics, toxicology, social organization, physiology, ecology, health, and effects of human activities on marine mammals.

firefox restore
Firefox is my web development platform, and I find that I often have to kill and restart it to test things, so I have the alias "kf" that kills my firefox.
alias kf='killall -9 firefox-bin'
The new update of firefox now gives me a dialog box asking to restore my session when I kill it, which wastes some time, and is almost never what I want to happen.
about:config to the rescue:
browser.sessionstore.resume_from_crash;false

NEPTUNE
CANARIE has awarded $980,000 in new funding to support some exciting new approaches to data collection and analysis. Data collection will be enhanced by installation of a "mini-observatory" at a nearby secondary school. Data analysis will be augmented by two new software-enabled approaches.

Trying to remember how to login to the Nethack Tournament this year. Need to ascend at least one character this year, to keep up my geek cred. After my Ph.D. I might try for the Grand Slam, but that would be a lot of Nethacking.

Duchess Says is a fantastic band out of Montreal that I'm really digging right now.
This is yet another great band that I found through xlr8r tv, an awesome video podcast about music and music tech.
