boot firmware error message
Posted: 30 March 2013 Filed under: arch linux, laptop Leave a comment »Install the wireless interface’s firmware with:
pacman -S ipw2200-fw
Or, if you won’t be using the wireless interface, add to /etc/modprobe.d/modprobe.conf
blacklist ipw2200
to get rid of the boot message about failing to install the firmware.

# systemctl rescue
# mount -o ro,remount /
# fdisk /dev/mmcblk0
Delete the second partition /dev/mmcblk0p2.

Create a new primary partition and use default sizes prompted. This will then create a partiton that fills the disk.

Save and exit fdisk:

Reboot, go single user, and run resize2fs:
# shutdown -r now
# systemctl rescue
# resize2fs /dev/mmcblk0p2
Your main / partition should be the full size of the disk now. Don’t remount the root partition read-only before you run resize2fs; resize2fs fails if it’s mounted read-only.
After running resize2fs reboot, go to single user, remount root read-only, run e2fsck, then reboot to bring the system back up multi-user:
# shutdown -r now
# systemctl rescue
# mount -o ro,remount /
# e2fsck /dev/mmcblk0p2
# shutdown -r now

Bring the system down to single user mode:
# systemctl rescue -
Remount root readonly
mount -o ro,remount /
Doesn’t work on the laptop; complains that the filesystem is busy.
Test fishermen’s rib with cotton yarn 2
Posted: 23 December 2011 Filed under: knitting 1 Comment »I made this one with size 7 needles; the previous one was with size 10 needles. The cotton is the Sugar ‘n Cream, Earth Ombre color, worsted weight; it calls for US #9, 5.5 mm needles.
I think I like the version made with size 7 needles better; it’s a little tighter but not too tight. It’s the one on the right; the left one is the one made with size 10 needles.
It will be interesting to see how they look after a run through the washer and dryer.
