Erlang has no locks and no keys.

Erlang processes don't share memory, so there is no need to lock the memory while it is being used. Where there are locks, there are keys that can get lost. What happens when you lose your keys? You panic and don't know what to do. That's what happens in software systems when you lose your keys and your locks go wrong.

Distributed software systems with locks and keys always go wrong.

Erlang has no locks and no keys.

Joe Armstrong, Programming Erlang

California driving test: passed!

I passed the California driving test this afternoon, now the streets are no longer safe :-)
The interim driver license looks really shabby, it's just this text printed on cheap copier paper:

                        INTERIM DRIVER LICENSE 

                  DXXXXXXX        CLASS C 


            ISSUED:07-25-07   XXX   XX/XX   EXPIRES:09-22-07

ANDREAS RENE JAGGI                       SEX:M   HAIR:BRN   EYES:HZL
900 ISLAND DR STE 101                    HT:5-11   WT:187   DOB:01-22-84
REDWOOD CITY   CA  94065


  THIS LICENSE IS ISSUED AS A LICENSE TO DRIVE A MOTOR VEHICLE;
     IT DOES NOT ESTABLISH ELIGIBILITY FOR EMPLOYMENT, VOTER
                REGISTRATION, OR PUBLIC BENEFITS.

Also the driving test itself was more like a joke than a real test. I just had to drive around for about 10 minutes. No highway driving, no complicated intersections, no 'advanced' maneuvers, no real parallel parking. In fact the "parallel parking" part was to pull over to the curb and drive backwards 3 meters (w/o any other car around of course). And the most complicated maneuvers were to change lanes and to make a left turn at an intersection.

Bicycle stolen!

This afternoon some asshole has stolen my bicycle.
I left it locked to the bike rack at the Hillsdale Caltrain station for 5 hours while I went shopping in SF. And now it's gone :-(

Of course I called the police, but even the deputy sheriff of San Mateo county said that I will probably never see my bike again.
So if you happen to find or see a bicycle with the following characteristics, please tell me (650.888.0140) or report to the police.

Serial# IDC07B22590
Brand GT
Model Avalanche 3.0 (2007)
Color black
Size XL

Kuriose Fakten über mich

Robert will zum Wochenende noch ein paar Fakten sehen:

  1. Ich hasse Arbeiten Schreiben, Lernen, etc. aber trotzdem sitze ich seit 15½ Jahren hinter der Schulbank (und bin damit noch immer nicht fertig).
  2. Im nächsten Semester gehe ich endlich mal nicht zur Schule sondern mache Ferien in Kalifornien programmiere bei Novawave Technologies an Embedded Linux Geräten herum.
  3. Je mehr ich neben dem Studium mache, desto besser werden meine Noten.
  4. Vor langer Zeit habe ich einmal Schlagzeug gespielt.
  5. Vor noch längerer Zeit sogar Blockflöte.
  6. Zwei mal pro Woche fahre ich über eine der schönsten Bahnstrecken und dabei schlafe ich oder starre in meinen Laptop.
  7. Ich interessiere mich für Eventtechnik und nicht zu wenig (Satellite, Balélec, Challenge 06, Artiphys, Vivapoly, ClosedAir 06, Polybeach, PIP).

Mal schauen ob Andreas oder Gordon was über sich erzählen wollen.
