birthday reminders, vCard to e-mail
Posted by on August 16, 2010
A couple of months ago I wrote a Python script which parses my vCard address book and reminds me about upcoming birthdays. Given that it has worked well for me I figured I would share it with the rest of you.
I have not added any e-mail capabilities to the script, as I find it cleaner to simply let cron pass along the output. For more information, see the README file.
(The actual vCard parsing is handled by the Python vobject library.)
OpenPGP key transition
Posted by on August 15, 2010
I’ve recently set up a stronger (4096R) OpenPGP key, and will be transitioning away from my old (1024D) one. To a large extent this is about being able to use the SHA-2 family for signatures.
The old key will continue to be valid for some time, but I prefer all future correspondence to come to the new one. I would also like this new key to be re-integrated into the web of trust. Please see this statement signed with both keys, certifying the transition.
The old key was:
pub 1024D/FAF2463A 2006-11-20
Key fingerprint = 4947 BB72 9192 8645 CC8B F142 8AF2 8D1C FAF2 463A
The new key is:
pub 4096R/13CD4F59 2010-07-11
Key fingerprint = AFEB 2D24 4715 3F0D 9250 8A8B 5882 A0DC 13CD 4F59
uid Andreas Olsson
uid Andreas Olsson
uid Andreas Olsson
uid Andreas Olsson
sub 4096R/9A943D4A 2010-07-11
To fetch my new key from a public key server, you can simply do:
$ gpg --keyserver pool.sks-keyservers.net --recv-key 0x13CD4F59
If you already know my old key, you can now verify that the new key is signed by the old one:
$ gpg --check-sigs 0x13CD4F59
If you are satisfied that you’ve got the right key, and the UIDs match what you expect, I’d appreciate it if you would sign my key:
$ gpg --sign-key 0x13CD4F59
Lastly, if you could upload these signatures, I would appreciate it:
$ gpg --keyserver pool.sks-keyservers.net --send-key 0x13CD4F59
Please let me know if there is any trouble, and sorry for the inconvenience.
Vacation in New York, Philadelphia and Washington DC?
Posted by on August 12, 2010
Hello Lazyweb
Currently I have my vacation coming up. During that time off me and a friend will be spending the last two weeks in August visiting the north-east part of the US. More specifically we will be visiting the cities New York, Philadelphia and Washington DC.
Any suggestions on things to do, places to see, etc would be most welcome.
(Yes, I have found my way to wikitravel.org. Great site!)
Linköping Launchpad workshop

Tomorrow evening, Monday that is, I will be hosting a Launchpad workshop in Linköping. It will be held together with “Dataföreningen” and their Ubuntu network. Primarily we will focus on using Launchpad for any (FOSS) project, while at the same time cover a few Ubuntu specific cases.

OpenID relying parties
Posted by on March 15, 2010
Being a big fan of the OpenID concept I’m quite happy that at least a few of the sites I like to visit are relying parties. Primarily I’m thinking of these sites:
Where do you login using your OpenID?
Using the YubiKey
Posted by on March 7, 2010
One of the keys I carry around on my keyring is a YubiKey. This post really isn’t about the YubiKey itself, but more about me sharing a few insights I’ve gained on using the key.
- If you already run a WordPress blog you can easily turn it into an OpenID provider to be used with your YubiKey. What you need is the OpenID plugin and the YubiKey plugin.
- If you decide to personalize your YubiKey I can very much recommend the DuckCorp YubikeyHelp, in addition to the official documentation.
- The new 2.x version of yubikey-val-server-php seems to prefer being part of a group of validation servers, being kept in sync with each other. Failing to figure out how to configure my standalone installation to disregard that synchronization I modified ykval-verify.php (see patch) not to perform those checks.
- The YubiKey WordPress plugin mentioned earlier is hardcoded into using the official Yubico validation server. Apart from the validation URL, set in the function yubikey_verify_otp(), there is also the length of the key id. Just look for the numeric value 12 and you will find where the key id is being used.
No, this post is not meant to make sense on its own. You probably need to be at least somewhat familiar with the YubiKey as well as the services provided by Yubico.
xkcd system administrator

Seems like there has been quite a few visitors coming to this blog after having done a google search on xkcd system administrator. To spare future visitors the disappointment I might just as well post the content I believe they were looking for.

zfs-fuse.net
Posted by on March 6, 2010
Yet again things are happening in regards to the FUSE version of ZFS. That is something you very well might have missed if you, like me, had satisfied yourself with subscribing to the zfs-on-fuse.blogspot.com RSS feed.
Apparently zfs-fuse.net is where all the action takes place nowdays.
Yes I know that Btrfs most likely is the future of Linux filesystems. Yet I can’t completely shake my crush on ZFS.
