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.

resizing the raspi flash card

# 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.
Test fishermen’s rib with cotton yarn
Posted: 22 December 2011 Filed under: knitting 2 Comments »The cotton is the Sugar ‘n Cream, Earth Ombre color, worsted weight; it calls for US #9, 5.5 mm needles. I used #10 needles.
As usual my borders are a mess.
It’s fairly light and fluffy; I could see using it for a scarf. Although the yarn would probably snag on everything since it’s so loose.
I’m going to try it again on #7 needles.
I used the first one, A. The square brackets delineate what to repeat.

My first knitting project
Posted: 13 December 2011 Filed under: knitting 1 Comment »A pot holder. I’m using cotton yarn and the seed stitch (aka the moss stitch). The yarn is multicolored; teal, brown, and off white. I’m about halfway or so done.
Since it’s cotton I can just toss it in the washing machine. I’m hoping that the first wash will help even out the unevenness of my knitting.
See if you can find the flub in the lower left corner!
