DebConf provisional schedule draft and holidays

Good news, the DebConf provisional schedule is finally available. If you see any problem, please, let us to know at schedule@debconf.org

If you are interested in Debian and Free Software and close to Cáceres, you are very welcome to come to the Debian Open Day on 24th July. The schedule for the Open Day is still not closed but you can see some of the planned talks already.

They were 2 long days trying to put it all together. What I was planning to do last weekend was mostly planning my holidays through Iceland, but ended doing this instead. Funnily, what Andreas Tille was mostly planning to do in the weekend was the DebConf scheduling, but he spend some hours in the saturday writing a mail about Iceland that has almost become my planning for the holidays :)
He documented his mail with some of his great pictures. If you were amazed by earlier pictures of Iceland in Planet Debian, check Andreas' !


The freedom to choose

John, no need to be so alarmist, this is KDE, look at the options:

Creating a new GPG key

I wanted to renew my GPG key for some time and after reading the latest news, I finally have generated a new key today.

pub   4096R/6AA15948 2009-05-10
      Key fingerprint = 7A33 ECAA 188B 96F2 7C91  7288 B346 4F89 6AA1 5948
uid                  Ana Beatriz Guerrero López <ana@ekaia.org>
uid                  Ana Beatriz Guerrero López <ana@debian.org>
sub   4096R/2497B8B2 2009-05-10


Since I tend to forget this stuff, I am blogging all the steps I have followed.
Long and verbose post follows...

Update .gnupg/gpg.conf

Add at the end of the file:

personal-digest-preferences SHA256
cert-digest-algo SHA256
default-preference-list SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES CAST5 ZLIB BZIP2 ZIP Uncompressed

Create key

Update September'2009: If you are using gnupg 1.4.0 or higher, the options have changed. You can select directly the option (1) RSA and RSA (default), then you also create a subkey for encryption at the same time you create your new key and you can skip the “Add subkey for encryption” step.

ana@pryan:~$ gpg --gen-key
 ...

Please select what kind of key you want:
   (1) DSA and Elgamal (default)        
   (2) DSA (sign only)                  
   (5) RSA (sign only)                  
Your selection? 5                       
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 4096           
Requested keysize is 4096 bits                  
Please specify how long the key should be valid.
         0 = key does not expire
        = key expires in n days
      w = key expires in n weeks
      m = key expires in n months
      y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y
