Use the SMS Service present in Koha to send Notices to Patrons

SMS Plugin which send Notices as JSON Data to an Endpoint using POST, Endpoint can be yours own endpoint or a service provided by a service provider. Handle the JSON data in Endpoint and send the Notice using your Custom Code or Service Provider to WhatsApp / Telegram / Whatever

GIT Repository : https://github.com/abhisheknagar/wa

JSON POST made by this Koha Plugin to Endpoint will look as follows : 

{
           "api_key"        => $api_key,
           "customerFirstName" => $patron->firstname,
           "customerLastName"  => $patron->surname,
           "phone"             => $patron->smsalertnumber || $patron->phone,
           "code"              => $m->letter_code,
           "messageBody"       => $m->content,
    }

Community Driven world's first free and open source library system, Koha https://koha-community.org/ powers major libararies around the world. 

No one likes a silence when tuning to a radio station, and for a radio manager its tough to have 24*7 programmes, in case you are running an Internet Radio Station using Airtime you probably would be programming your shows and in Offtime your radio is always silent i would suggest you to play some random tracks in this Offtime and also include a track which tells when your station plays live so here is how to achieve this

1. Put some MP3 files in a folder of your server, please also record a message with the showtimings etc or what ever you want this folder may contain any number of files which you want to play in off time (Folder used in the below script /store00/rand)
2. Edit /usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_script.liq (below is the patch) the modified lines are in bold

-default = amplify(id="silence_src", 0.00001, noise())
+#default = amplify(id="silence_src", 0.00001, noise())
 ref_off_air_meta = ref off_air_meta
 if !ref_off_air_meta == "" then
     ref_off_air_meta := "Airtime - offline"
 end
-default = rewrite_metadata([("title", !ref_off_air_meta)], default)
-ignore(output.dummy(default, fallible=true))

+#default = rewrite_metadata([("title", !ref_off_air_meta)], default)
+#ignore(output.dummy(default, fallible=true))
+default = playlist(mode='random', "/store00/rand/")
 master_dj_enabled = ref false
 live_dj_enabled = ref false
 scheduled_play_enabled = ref false

Once you have modifed you are good to go restart the services, upon restarting you will listem random tracks in offtime from the folder you have set in the script.

Tested on Airtime 2.5.1, do listem to VMOU's stream @ http://vmou.ac.in/stream

I am sure you would have come to a situation when you would have to resize multiple images say you copied 200 images from your Digital Camera and now need to upload them and need to resize them all, now doing this using GIMP would take ages here is a easy way.

Step 1) Install ImageMagick

sudo apt-get install imagemagick

Step 2) Change to the Directory where all Images are Present

Step 3)

a) If you need to reduce images to a specific Percentage

mogrify -resize 20% -format jpg *

b) If you need to reduce to Specific Width & Height

mogrify -resize 800x600 -format jpg *

c) If you need to reduce to Specific Width

mogrify -resize 1024x -format jpg *

Hopefully there would be many like me who have struggled in configuring Broadcom Wifi Cards on Linux due to their proprietory drivers, now a days it works fine in Ubuntu if you download the drivers available but still it doesnot work with various other distros. so here is a 3 step guide to configure Broadcom Wifi on your linux box these steps have been tested on openSUSE but would work on any distro Step 1 ) Download a file from here. Step 2) Install bcm43xx-fwcutter it is commonly avaiable for all distros Step 3 ) follow the commands

# bcm43xx-fwcutter wl_apsta-3.130.20.0.o

(bcm43xx-fwcutter is the application which u have installed wl_apsta-3.130.20.0.o is the file which you have downloaded from this blog:)  preferably create a directory and copy wl_apsta-3.130.20.0.o there and execute the command in the directory)

# cp *.wl /lib/firmware

(*.wl are the files which were generated from the command above there would be some 16 files)

And you are done use the network manager to configure Wireless Netwoks :) this was really simple. Desclaimer: code/commands given in the posts worked fine for the author please use them on your own risks they may damage your system.

GNUnify is one of the biggest FOSS event which is completely managed and organized by the students of Symbiosis Institute of Computer Studies & Research. Each batch of MSc (CA) only gets one opportunity to organize it last time we "RESPAWN" organized and the tradition continued with the current batch which organized the 7th GNUnify. It was sponsored by Mozilla, they also presented a few talks this year which were great. I also got an opportunity to conduct a workshop this year which  went on well the participants were able to create websites on their local machines atleast :) this was the second time when i got the opportunity to be a speaker @ gnunify.

This year we had more then 50 speakers covering topics in various areas of software development, administration the new addition this year was the FOSS in academics Track where in teachers from various colleges came up and discussed about FOSS.
