Morgens in der Stadt

Sonnenstrahlen helfen

Eigentlich habe ich die Stadt im Moment etwas über. Aber früh am morgen gefällt es mir immer noch in der Stadt zu sein. Am besten natürlich an einem sonnigen Tag, von denen haben wir ja glücklicherweise genug hier. Früh morgens aus dem Haus gehen, um eine Bougatsa zum Frühstück zu holen. Das Sonnenlicht auf den Häusern, Menschen, die zur Arbeit gehen oder im Quartier einkaufen.

Saturday Ride Report: Dervenohoria

Some decent climbing, not so decent climber
Map of our Dervenohoria ride

Last Saturday I was out riding with my friend George. We went to some mountains to the north-west of Athens. First we had to pass a lot of industrialized areas in direction to Elefsina, riding on the shoulder of big roads, not really my preferred thing. Then we passed through the plain near Aspropirgos. Here we had smaller roads and with much less traffic.

Then the climbing started: At first on a long, straight stretch that is still part of the plain, with a gradient of 1-2%. Then getting bit by bit steeper up, and finally arriving in the forested slopes of the mountains. After a bridge, the real climb starts: 8.3km with an average gradient of 5.7%. Less steep at first, more steep towards the end. Shortly before the top there is the first "peak" which marks the arrival at the pass height, the road going almost down a bit and then one last climb to the road's peak.

At first George and me had started the climb together, but after the first kilometers I lost him - his higher gearing definitely doesn't help there. So I soldiered on by myself. Lots of trucks passed, but in generally with enough space on the road to be ok. One of the truck pushed out a huge cloud of exhaust, both in passing me and continuing on uphill. The fume lingered on, which was very tough to ride on and one of the times where I wished for a bit more wind to get it away. By that time I was also already feeling exhausted, mustering my strength just to not stop till I reached the peak. When I got there, I waited for George and had some time to recover.

Down we went, onto a high plateau and a village where we filled up on water. We had the best of weather, sunny but still fresh. The plateau was very interesting. It looked to me like a forgotten place. Empty and forgotten so close to the big city. We continued through the plain to the exit on the south-east. First some more climbing to get over the "border" of the plateau, then a huge downhill ride. This part again was forested and looked empty and forgotten, except for one town with a collection of huge tavernas advertising lamb chops and stuff like that. We hadn't seen a sheep in all the ride, so I guess the taverna customers don't mind that their meat arrives on the same roads as they do.

We kept on our return, through ever slightly more crowded streets, through the industrial areas again. In the Athens neighborhoods we hit on Saturday shopping traffic, but after having lunch at George's place, everything was calm on the way back to my place. I felt tired and done, but had no sore legs. I just wanted to go out again as soon as possible and get this climb done properly.

Distance: 110km, 1470m elevation gain, 4:40 riding time, average speed riding (without the stops): 23.6km/h.

New PGP Key

Please update

It's time to upgrade my PGP key. The old one was created more than 10 years ago and the key length isn't up to today's standards any more.

The new key ID is C4D2D0F8 / long ID CC57D031C4D2D0F8.

I have prepared one of those fancy "transition statements". You can find it here, signed by my old key and signed by my new key

Thursday, 2013-11-14

Since my old key was very old and had a smallish key size, I've
recently set up a new OpenPGP key, and will start using the new
one from now on.

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.  This message is
signed by both keys to certify the transition.

the old key was:

pub   1024D/E0EAFC8A 2002-01-24
      Key fingerprint = 067B 60E1 CB03 50CE D781  42E9 A583 AAF4 E0EA FC8A

And the new key is:

pub   4096R/C4D2D0F8 2013-10-05
      Key fingerprint = B0C9 F0D2 2432 1C05 4688  34EF CC57 D031 C4D2 D0F8

(Long key ID: CC57D031C4D2D0F8)

You can get the full key from this address:

  http://betabug.ch/sascha_welter_pub.txt

Or, to fetch my new key from a public key server, you can simply do:

  gpg --keyserver pgp.mit.edu --recv-key C4D2D0F8
  or
  gpg --keyserver keys.gnupg.net --recv-key C4D2D0F8

If you already know my old key, you can now verify that the new key is
signed by the old one:

  gpg --check-sigs C4D2D0F8

If you don't already know my old key, you can check the fingerprint
against the one above. If you want to be double extra paranoid, check
the fingerprint against the one you get from me personally in writing:

  gpg --fingerprint C4D2D0F8

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 C4D2D0F8

Lastly, if you could upload these signatures, i would appreciate it.
You can either send me an e-mail with the new signatures (if you have
a functional MTA on your system):

  gpg --armor --export D21739E9 | mail -s 'OpenPGP Signatures' sw@betabug.ch

Or you can just upload the signatures to a public keyserver directly:

  gpg --keyserver pgp.mit.edu --send-key C4D2D0F8
  or
  gpg --keyserver keys.gnupg.net --send-key C4D2D0F8

Please let me know if there is any trouble, and sorry for the
inconvenience.

Regards,
Sascha

In short: I'll start using the new key. Please get it from the key server or my server, then check the signature of my old key on it and the fingerprint with me. Then please sign the new key and upload to the keyserver or send to me.

Thanks, and be safe out there!
