Going to experiment with recording audio with Lucinda’s Mac:

Tried to scan, and xscanimage was broken. Had to recompile from ports and reinstall. Had to edit /usr/local/etc/sane.d/epson.conf to point the ‘epson’ backend at the USB scanner. Tried to print, and ran out of black ink. Put in a new cartridge.

Got a new 256MB PC133 DIMM from Staples to replace the one that had gone bad. $54.06 with tax. Sent in for the $20 rebate from PNY.

Lucinda knows how to tie her shoes now. She is, of course, very pleased with this.

I installed the ‘audio/mad’ port which can convert MP3 to PCM:

moe# madplay -v -o raw:Entropy.pcm Entropy.mp3
MPEG Audio Decoder 0.14.2 (beta) - Copyright (C) 2000-2001 Robert Leslie
     Title: Entropy
    Artist: MC Hawking
     Album: A Brief History of Rhyme
      Year: 1994
     Genre: Rap
 00:03:21 Layer III, 128 kbps, 44100 Hz, joint stereo (MS), no CRC
7722 frames decoded (0:03:21.7), +0.2 dB peak amplitude, 7 clipped samples

Then to burn them to a CD:

moe# burncd -f /dev/acd0a audio  mighty.pcm emchawking.pcm creation.pcm crazy.pcm LedZeppelinMedley.pcm JesseHelms.pcm Entropy.pcm fixate

Here is the rundown on the instability problem. The system hung and had to be unwedged on:

2003/11/01  08:28
2003/11/02  05:44
2003/11/03  21:59
2003/11/05  13:13
2003/11/09  15:38
2003/11/11  11:44
2003/11/12  09:09
2003/11/15  11:45

The average uptime between hangs was 28 hours, with a maximum of 78 hours.

Found out how to read audio CDs:

dd if=/dev/acd0t1 of=test.dat bs=2352

This reads track 1 off the CD and puts in file as raw PCM data. Also, it is necessary to create the ‘acd0tX’ devices:

cd /dev
./MAKEDEV acd0t99

All the futzing around with X over the weekend broke mod_php’s graphics capability. I think this is because I had to install a new version of expat. I rebuilt mod_php and now it works again.

Installed a new ATAPI CD writer on Moe today. I was able to sucessfully burn a CD of the contents of our web pages. The procedure was:

moe# mkisofs -L -R -o output.raw /home/html
moe# burncd -f /dev/acd0a data output.raw fixate
next writeable LBA 0
writing from file output.raw size 133120 KB
written this track 133120 KB (100%) total 133120 KB
fixating CD, please wait..

I was able to then mount and read the CD, so I guess it worked.

Went to the office this morning and retrieved the old PC100 memory from my old computer in the junk pile. Brought it home and reassembled Moe with all the original components, but with the old memory. So far it hasn’t locked up, so I’m hopeful.
