It outputs NMEA format files, which I  normally convert into the more widely used GPX files, using GPSBabel. Once I have my GPX file I use the excellemt GPSPhotoLinker to embed the GPS coordinate information into the EXIF of my photos.

Anyway, I never remember this, so to remove and then re-add a disk from a md device do the following:


[root@host ~]# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb1[1] sda1[0]
104320 blocks [2/2] [UU]

md0 : active raid1 sdc1[0] sdd1[2](F)
143371968 blocks [2/1] [U_]

unused devices:
[root@host ~]#


And there we can see from /proc/mdstat that the md device will be synchronised and happy again soon.

(parted) mkpart primary 0 100%

That is all.

Essentially you use the taskset command to run a new proc locked to a specific CPU:

% taskset -c 1 sleep 10

Will run ‘sleep 10′ locked to CPU #0.

% taskset -c -p 1
pid 1's current affinity list: 0,1

Shows you what PID 1 has its affinity set to.

These instructions worked on my iMac and my MacBook Pro both of which were running 10.5.7.

Before you start, make sure the modem is not connected.

First off download the drivers, the ones buried in the three.co.uk support site lack a actual installer even though the documentation suggests you just need to run the installer. WTF am I supposed to do with a bunch of .kext files three? Have you heard of a nice user experience? Clearly not. Click this link and download the zip file from here, inside is a standard OSX installer package. run that.

After that has installed, you dont need to reboot. Plug in the modem and wait a few minutes. The little LED started flashing blue occasionally for me which I think means I’ve got 3G coverage.

Once its calmed down open up network preferences where you should see a few new devices down the left hand side:

The device you are interested in is the HUAWEI Mobile, select that. Then in the ‘Telephone Number’ field enter *99#:

After you have done that click the ‘Advanced’ button. On the resulting pane, select ‘Generic’ from the Vendor drop down. Then select ‘GPRS (GSM/3G)’ from the Model field. If you are in the UK, enter ‘three.co.uk’ into the APN field and leave the CID as 1:

Click ok, and then click Apply on the main Network Preferences pane. After you’ve done this try clicking connect and you should see the following connection confirmation:

A nice little utility to monitor your connection is CheetahWatch which you can get from here.

Once you have vmware-tools installed and configured try this:

/usr/sbin/vmware-guestd --cmd "vmx.set_option synctime 0 1"

To verify this has worked look for this line in the corresponding .vmx file:

tools.syncTime = "TRUE"

% export PATH=/Library/Application\ Support/VMware\ Fusion/:$PATH
% vmrun listSnapshots SpaceWalk.vmx
Total snapshots: 1
Fresh 5.2 all updates
% vmrun -T fusion snapshot SpaceWalk.vmx "SpaceWalk Installed"
% vmrun listSnapshots SpaceWalk.vmx
Total snapshots: 2
Fresh 5.2 all updates
SpaceWalk Installed

To check you are logged in:

wget --keep-session-cookies \

grep the page for ‘Logged’ you should see it say something like ‘Logged in user: blah’.

Also look towards the bottom of the page for the ‘multiform’ hidden form element, you need the value which is a string, something like ‘jaoEEPpxzAhfadQZ/dpO/A341374′

To add an entry:

NAME=test
IP=1.2.3.4

If you want to see the time of each ping, use -s which makes it more like the GNU Ping you find on linux:

% ping -s foo
