Watch Darsha create glitch music- 20 OSCILLATORS IN 20 MINUTES [32c3]

I’ve always been fascinated by the music culture documented in the Create Digital Music blog. Growing up with a mother who loves to learn and a father that is a hard working painter, I understood how knowledge is a tool for creativity. The  more I know (say, how to create a circuit that produces oscillating sound), the more options for creativity I have (for example, layering 20 oscillators to hear super interesting sounds).

Speak better: E-Prime is a new english language subset that forces more interesting writing

Force yourself to remove all forms of the verb “to be” from your writing by E-Prime:

We see the misuse and overuse of the verb “to be” by English speakers as a kind of linguistic addiction. It allows us to play God using the omnis-cient “Deity mode” of speech, as when we say, “That is the truth .’ It allows even the most ignorant to transform their opinions magically into god-like pronouncements on the nature of things. Its overuse allows one to com- municate sloppily without unduly taxing the brain by trying to come up with more appropriate verbs .

Installing Airtime 2.5.2 on Ubuntu 14.4 Trusty

Airtime is an open source online radio software that has an intuitive interface to drag and drop shows for simple programming. I don’t recommend installing it, unless you have multiple shows, with multiple hosts and need to create “smart groupings” of music on a repeating calendar.
Or, unless you like a challenge. 🙂
I was curious because I thought it would be “fun” to try using an automated online radio system.

Officially, the install should be pretty easy.
Here is a nice video explaining it:

Airtime. Open software for radio stations. from Sourcefabric on Vimeo.

After uninstalling Airtime, when running apt-get dist-upgrade the following errors appeared:

   
Setting up airtime (2.5.1-6) ...
Setting up apache2...
Site airtime-vhost already disabled
Apache 2.4 detected, using newer access configuration...
sed: can't read /etc/airtime/apache24.vhost.tpl: No such file or directory
dpkg: error processing package airtime (--configure):
subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
airtimeE: Sub-process /usr/bin/dpkg returned an error code (1)

The solution was to purge all Apache’s configuration file to remove anything related to Airtime:

    
sudo apt-get remove --purge apache2 apache2-utils

which detected Airtime’s installation that had not completed:

    
The following packages will be REMOVED:
airtime* airtime-easy-setup* apache2* apache2-mpm-prefork*
libapache2-mod-php5*

Running

After running 

    sudo apt-get update

I get the error: 

    W: Duplicate sources.list entry http://apt.sourcefabric.org/ trusty/main i386 Packages (/var/lib/apt/lists/apt.sourcefabric.org_dists_trusty_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

However, /etc/apt/sources.list didn’t show any duplicates. This link suggested looking at /etc/apt/sources.list.d for the culprit. Yep, a duplicate entry was listed there: (Perhaps from Airtime 2.5.1?)

    cat /etc/apt/sources.list.d/sourcefabric.list
# Sourcefabric package repository
deb http://apt.sourcefabric.org/ trusty main

# Debian squeeze backports repository, not needed for Ubuntu or Debian wheezy
#deb http://backports.debian.org/debian-backports squeeze-backports main

The Debian squeeze line is commented out, and I already have a sourcefabric source line in the sources.list file, so I just removed it: 

    sudo rm /etc/apt/sources.list.d/sourcefabric.list

.

Ok! Our sources are sorted, so now I can actually install Airtime:

sudo apt-get install airtime
