cheap portable hard disks a go go

I decided to buy a portable hard disk this week for my trip to germany, so that I can ensure I don’t run out of CF space.

It’s a vosonic vp2160, and at £109 for a 60gb model I’m pretty happy. It happily reads my CF card fresh from the camera, and copies over all the images pretty speedily.

The interface is super simple and easy to use, it doesn’t play music or anything like that, but all I wanted it for was to store pictures on till I get home and can process the images.

The USB2.0 interface is speedy enough to copy over files i’ve copied to the disk, and also allows you to use the device as a CF/MMC/whatever reader for your PC, which is handy. It’s pretty handy too how you can charge the Li-ion battery via USB too (you have to plug two usb connectors into your pc, but that’s no biggie really)

What really impressed me the most, however, is how it actually seems to suggest you should be fine upgrading the hard disk at some point. They include (amongst the power adapter to charge it up and the install cd for win98 drivers etc) a mini screwdriver to uncouple the back off it, which reveals a bog standard fujitsu 2.5″ hard disk. So if I decide 60gb isn’t enough in this little device I will be able to have a good go at upgrading the hard disk!.

I also purchased a Creative Zen Vision:M 30gb today too today to tide me for my trip to germany, but will druel more at that when it arrives tomorrow

Virtual domains in exim4

I’ve been using exim for a while with virtual domain support, and thought it be best to document what I did somewhere.

For a long time I wondered how I might actually support virtual domains in exim 4 and held off by just dumping all mail from all domains into my mailbox (how gosh darn lazy is that).

I finally got bothered enough to, and found a lot of easy to follow help on the internets (google), and came up with the following additions to my exim4.conf :


domainlist localdomains = dsearch;/etc/exim4/virtual : @ : localhost

and in the routers section

begin routers
...
vdom_aliases:
driver = redirect
allow_defer
allow_fail
domains = dsearch;/etc/exim4/virtual
data = ${expand:${lookup{$local_part}lsearch*@{/etc/exim4/virtual/$domain}}}
retry_use_local_part
pipe_transport = address_pipe
file_transport = address_file
no_more


As you can see there is a directory called /etc/exim4/virtual, which contains several files, each of which define the aliases for a domain, an example file in that directory could look like:
filename: thefraggle.com


* : :fail:
chris : chris@localhost


As you can see this looks pretty simalar to the sendmail aliases file, but requires no rebuilding (if you have used sendmail at some point, you’ll know that you need to issue a “newaliases” command.

Anyway, hopefully that wasn’t too painful, any improvements, suggestions and other observations welcome!
