Subject: [Skunkworks] Power Backup - Inverter + battery
Message-ID: <4FE2E5A2.1040207@swiftkenya.com>
Content-Type: text/plain; charset=ISO-8859-1
Hi Folks,
Has anyone installed power backup solution that is based on an Inverter
system with a battery bank. Am looking for a SOHO solution and costs.
Additional information such as the load capacity, space requirements,
battery types/sizez (maintenance or maintenance free), inverter
features, etc would be appreciated.
Thanks,
Mich.

I would highly recommend either speaking to "Chloride Exide"
http://www.cekl.com/index.php?option=com_content&view=article&id=84&Itemid=27
or Davis and Shirtliff
http://www.dayliff.com/index.php?option=com_content&view=article&id=263&Itemid=265
as they have highly specialized power backup system solutions
(warranty+support included). There are a lot of other vendors that offer
the same,but it all comes down to cost. I am sure they will point you in
the right direction of what you need.
thanks
Vince

The trick here is using IFS (Internal Field Separator) to tell the shell to
split on newlines not whitespace.
However, that is serialized.. Let's slow things a bit by injecting some
ZZZs..

15 seconds for 3 messages! Since you are into bulk sms you might want
something a little bit faster. Enter xargs
1. Move sendsms into a standalone script that works on one line per
invocation
2. Parallel invoke the sendsms with xargs -P
??laban at ubuntu in /tmp @ '2012-06-21 22:00:16'
??? cat sendsms.sh
#!/bin/bash -
set -o nounset # Treat unset variables as an
error
sendsms () {
line=$1;
echo processing $line;
field1=$(echo $line | awk '{print $1}');
phone_no=$(echo $line | awk '{print $2}');
field3=$(echo $line | awk '{print $3}');
sleep 5;
echo "Processed -> $field1::$phone_no::$field3";
echo;
}
sendsms "$@"
