Today's achievements

Half an hour correcting dl.asp delivering 0 bytes to IE:

set fs=Server.CreateObject("Scripting.FileSystemObject")
set f=fs.GetFile(strFilePath)
strFileSize=f.Size

L bumped up the audio on AsiaStar, now it's fine.

Rest of the morning doing Bhajan processing.

Afternoon tracing schedule problem with DST: found probable locale change so that

if (date > #11/03/2007#) and (date < #04/11/2007#) then

has stopped working and now needs to be

if (date > #03/11/2007#) and (date < #11/04/2007#) then

So, changed it to locale independent

if (date > DateSerial(2007, 03, 11)) and (date < DateSerial(2007, 11, 04)) then

instead. We're not changing the changeover times because then the Latin Americans would have four changes to their regular programming every year - following US DST and their own DST.

And evening was spent on playlist generation.

newline in csv breaks database tables

A single bad newline in a description field had the schedule page down for the last half hour while we traced and corrected the problem... Caution needed when copy/pasting descriptions especially from text files / emails as in the case of Telugu programs!

bhajan processing

Starting slowly on Bhajan processing. Yield is roughly an hour's worth for a morning's work.

changes to add PHP 5 compatibility

The forms in maillist were not PHP5 compatible: as noted by P, in PHP5, the posted variables are not automatically available, but requires the addition of lines like

$variablename=$_REQUEST["variablename"];

Did the necessary additions by searching for the name=parts and thus the required variablename in the forms. Partially implemented, so that most frequently used pages work.

changed Daylight savings times

Changed the code for daylight savings times for USA-Canada and Israel for 2007 checking out the info from http://timeanddate.com/time/dst2007.html

on-demand links on schedule page

An interim solution implemented, which will work only for single file items. Probably, multi-file items will need a rethinking along the lines of my previous post. Current implementation uses a single extra filename field in the remote database. And the logic to automatically add this is

if ( ($CATEGORYNAME=="Special") OR ($CATEGORYNAME=="Discourse")  )
  {
  if (Strncmp($NEXT_FILENAME,$FILENAME,7))
    $DOWNLOAD_FILENAME=$FILENAME;

  if (strcasecmp(trim($NEXT_DESCRIPTION),trim($DESCRIPTION)) )
    $DOWNLOAD_FILENAME=$FILENAME;

    }

with

 $DOWNLOAD_FILENAME="";

if the condition fails.

audio distortion at AsiaStar uplink

There seemed to be considerable distortion in low frequencies, and M wanted the jingle during the start and end of Moments of Oneness to be broadcast undistorted. The line in the playout scripts was

mpg123 -o alsa09 -g 70 -q -a $DSP_DEVICE   "$line"

But the gain factor of 70% was not being set - probably some permissions issue. After IM and emails, L found the audio card bad, since using another one seems to give clear audio. But currently the DBMax is byepassed, so audio levels are sometimes low. Next task is to get it thru the DBMax.

play avi and wmv on MacOS X

Since we were mulling over the MirrorDome and such systems, just checking if DivX files play with QuickTime - this article links to some plugins to achieve this.

Windows media components for Quicktime is supposed to let you play Windows media files on Mac.

renewing postgres database from dump

My local copy of the SGH postgres database was out of date, so I picked up the dump from saiwaves

pg_dump sgh > /home/sgh/sghdbdump

Before loading onto my system, I had to remove the existing database with

dropdb sgh

then create it again with

createdb

and then run

psql -d sgh -f sghdbdump

Sirf kuch hi lamhon mein apka swadisht database tayyaar!

downloadable links on the schedule

For implementing downloadable links on the schedule page, we'll need some database changes at our end also - a "flag" saying allow/don't allow download - so that the appropriate data can be dumped into the csv file for import into remote database. Experimenting with adding a filename field to the AsiaStar schedule table...

new on-demand code

Quietly removed the embedded XSPF player from the on-demand pages, replacing it with the mp3player from http://www.jeroenwijering.com/?item=Flash_MP3_Player opening in a new window using a simple target="_blank" In replacing the old pages' code, learnt some regular expression syntax from KWrite's regular expression editor -
1. Reg Exps have to be only on a single line - end of line symbol $ terminates the regexp.
2. object.*$ means object followed by any characters till end of line.

Watch TV online

Got this link from Digg or Wired or somewhere:

iPod repair

Saw a Wired article on "iPod mechanics" repairing broken iPods, and checked out www.NYCiPodDoctor.com But the cost of replacing a hard disk on the old broken 1st Gen iPod is greater than the cost of buying a new flash-based mp3 player....

used iMacs

Found some nice deals via a google ad for used iMacs at megamacs.com - Apple iMac 233MHz Bondi 96MB, 4GB, CD for $29.99! But unfortunately we can't get them by normal shipping methods - there's a $200 anti-dumping duty, it appears!

virus attack

Like almost any all-Windows shop, the PDS was hit in 2nd half of Feb by a virus/worm which was creating a fun.exe in all folders, and spreading to all machines via shared folders. Norton Enterprise antivirus was not catching it or maybe because it was already loaded into memory, it was recreating instances. P finally cleaned it with AVG free + using msconfig to stop it from loading on startup.

problems connecting to our playout server

In the first part of Feb, we had some trouble connecting to our playout server at Melbourne. The traceroute was taking too many hops. Now, for example, the traceroute reaches the server in around 22 hops. A little on the high side?

trying de-clipping tools

Trying de-clipping tools like Cool Edit Pro's built-in and Acoustica's built-in on bhajan recordings. No use. Since it is the singer mic alone which has the distortion, and since it is added to all the rest, the mixed signal can't be cleaned by these sw.

H2H virtual folder

Changed the H2H virtual folder journals into a physical folder with a single line asp page redirecting to media.radiosai.org/journals
