Listener Feedback


(Colin about episode 65)
Hello Everyone,

Really appreciate the podcast, thanks a lot to all of you.
Just to let you know I downloaded episode 65 Oct 22nd and through tablet speakers or wired earphones or a new Bluetooth speaker the volume is so low you cannot realistically listen I’m afraid. I immediately switched to another podcast at the same volume and it boomed through.
Hopefully this is useful feedback.
Thanks again for the regular podcasts I am really enjoying the show.
Colin,
Belfast, Northern Ireland.

Hi,

I might be able to help with your networking issues.  I use Arch on Pi2 and my laptop.

You can either use wifi-menu to generate a network profile, or copy from /etc/netctl/examples to /etc/netctl/
To enable to profile, use <systemctl enable netctl@wlan_network_profile.service> and <systemctl start netctl@wlan_network_profile.service>
Be mindful of the not using a profile name with a dash in the name, but an underscore instead.  The profile fails to start with a dash.

Here is an example profile.

Interface=wlan0
Connection=wireless
Security=wpa
ESSID=ATTxxxx
IP=dhcp
WPAConfigFile=’/etc/wpa_supplicant/wpa_supplicant.conf’
Key=\”key_generated_by_wpa_passphrase
### \” before the key does matter, it won’t work otherwise
TimeoutDHCP=30

usage: wpa_passphrase <ssid> [passphrase]

And last, at the end of wpa_supplicant.conf

network={
ssid=”ATT159″
#psk=”3678167014″
psk=”03cbedf25145ce6c304b41946a47c854dd27b34058a141a7ec89cc270b13c9cb”
}

Fun with SOX
http://billposer.org/Linguistics/Computation/SoxTutorial.html

http://digitalcardboard.com/blog/2009/08/25/the-sox-of-silence/

How to truncate silence
sox -S in_file.wav out_file.wav silence 1 0.1 0% -1 0.1 0%

How to change the sample rate of an audio file
Sox in_file.wav -r (sample rate) out_file.wav

To combine multiple audio files (must have the same sample rate)
Sox file1.wav file2.wav file3.wav new_file.ogg

How to find out what the sample rate of an audio file is
Soxi file.wav

Netminer
I have found a nice low power Pfsense Box.   It has 4 Intel NICs, either a J1900 Quad core or
3215U dual core Intel processor and up to 8Gigs of Ram.  It is the QOTOM Q190G4.   The -S1 version supports an MSATA SSD, while the -S2 version can have 2.5 inch hard drive.
The units are very low power fanless industrial computers.  They are cool thru a finned metal
Top.  They are available from Amazon and Aliexpress
