Beginners Head-fi

Here are my first “high end” in-ear monitors. These Shure SE535 IEMs came my way from a fellow Audiokarma member. They are in great shape according to the original owner because they had recently been given to him as a replacement for an earlier model (maybe the SE530?). Being in chicago and only a few miles from Shure’s Chicago headquarters has it’s advantages. As the story goes, he walked into Shure after a

Here are some reader submitted photos of their Chi work. Continue reading “Chi Flatiron Repair – Fix it Yourself – User Photos”

Bash script to break apart a Mastery Manager Export

# This code is only for use under adult supervision. Proceed at your own risk. 🙂
#!/bin/bash
ORIGIFS=$IFS
# set $IFS to end-of-line
IFS=`echo -en “\n\b”`
if ( !$1 )
then
echo ‘usage: batch.command Name_Of_MM_Export_To_Process’;
break;

for l in $(cat $1 )
do
if `echo ${l} | grep  “Student” 1>/dev/null 2>&1`
#this line is the header, start a new output file
then

echo -n ‘.’
else
# this line is not a header, write it to the current file
echo $l >> $file.txt

plue a little one liner to rename the files using line 2, column 2 as the title.

SSRS Expressions: Scope and Commenting Tips

In SSRS, Scope is confusing as hell. Below is an example of adding comments to SSRS expressions and how to probe scope. Adding a line like:

iif(inscope(“matrix1_dept”),”[d]”,””)

will display a “[d]” in cells that are in the scope of group “matrix_dept”, and nothing if it is outside that
scope. By adding multiple scope tests, you can see where cells lie in the scheme of things.

Replacing The Fuse in a Panasonic TAU TV


Sure, this is a standard definition TV, and sure it is a CRT, but I love this TV. It has served us well for around 7 years and I still enjoy watching it. I take good care of the tv, use good cables, and keep it pluged into a power conditioner. However, yesterday when i turned it on to attempt to watch a little True Blood, the tv did not respond at all. I pressed the power button and saw no lights, no buzz, no hum. I checked all the power connections and power strips  that i could but no matter what i tried, the TV was dead.

After some googling i learned that this is a fairly common issue for this TV. I also learned that the problem may be resolved by simply replacing a fuse in the power supply. I was very happy to learn that I had a shot at resurrecting the TV without having to lift the monster to move it, and without having to take the main shell off of it.
