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 Comment: www.mchawking.com 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 next writeable LBA 0 writing from file mighty.pcm size 20664 KB written this track 20664 KB (100%) total 20664 KB next writeable LBA 9149 writing from file emchawking.pcm size 36306 KB written this track 36306 KB (100%) total 56971 KB next writeable LBA 25108 writing from file creation.pcm size 24408 KB written this track 24408 KB (100%) total 81380 KB next writeable LBA 35887 writing from file crazy.pcm size 24304 KB written this track 24305 KB (100%) total 105686 KB next writeable LBA 46621 writing from file LedZeppelinMedley.pcm size 54301 KB written this track 54302 KB (100%) total 159988 KB next writeable LBA 70415 writing from file JesseHelms.pcm size 33480 KB written this track 33481 KB (100%) total 193470 KB next writeable LBA 85144 writing from file Entropy.pcm size 34749 KB written this track 34749 KB (100%) total 228219 KB fixating CD, please wait..
Here is the rundown on the instability problem. The system hung and had to be unwedged on:
2003/11/01 08:28 20:14 2003/11/02 05:44 2003/11/03 21:59 2003/11/05 13:13 17:56 21:48 2003/11/09 15:38 19:50 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.
