Bike stiff : Powercranks X-Light

I'd used the last two month - ok nearly - to exercise with a piece of equipment called Powercranks X-Light. It's ridiculous expensive, heavy and awful looking! Assembling was straight forward and didn't result in any difficulties.
The Marketing f*gs sell it as:

"PowerCranks, when integrated into the normal training routine, allow the athlete to achieve more than was ever possible before. This one tool will allow the user to:

1. Train important muscles, undertrained in almost everyone (more)
2. Ensure your leg and core muscles are balanced (more)
3. Improve running and cycling speed/power (more)
4. Improve running and cycling technique (more)
5. Improve running and cycling efficiency (more)
6. Reduce your risk of injury (more)
7. Improve training time management (more)
8. Improve rehabilitation outcome after injury or surgery (more)
9. Increase your VO2max (more)
10. Plyometrics without the injury risk (more)
11. Other possible health improvements (more) "

The points listed results mainly from the fact that the two crank arms backward freewheel works independently and you are forced to synchronize the pedal stroke. Get it? This sounds "more or less" logic...

The first 20 minutes of training was:
pedal stroke -- pedal stroke -- *wtf* -- *laughing* -- pedal stroke*10 -- *cursing* -- pedal stroke*20 -- *more cursing* -- 5 minutes pedaling -- *pain* -- *cursing* -- 10 minutes pedaling -- stop.

After 1 month of training on the roller I came to the conclusion that it's just a waste of money and decided to sell it on ebay. My decision is based upon the feeling, that I am just one of those "mashing guys". Wanna say, my quads and gluteus' are used to do the job!

Thank you

Die Namensauflösung bei Linux (DNS resolve) funktioniert nach einem bestimmten Schema. Dieses ist folgend aufgelistet, wobei SYSV, BSE auf die Vorlieben der Distribution hindeutet.

1. Nameserviceswitch /etc/nsswitch.conf SysV
2. prehistoric libc-legacy /etc/host.conf BSE
3. libc DNS resolver /etc/resolv.conf BSE wie SysV

Wenn der Nameserviceswitch besagt, dass Anstelle von dns lieber files
befragt werden sollen, schaut der Resolver direkt nach 1. in /etc/hosts nach.
(Gegebenenfalls in der aufgeführten Reihenfolge)

Eventuell ist der Nameservicecachedeamon (nscd) aktiv. Dieser ist bei
Resolvingproblemen am sinnvollsten praeventiv zu toeten (pkill -9 nscd)

Der sinnvollste Einsatz von nscd ist an die Verwendung von LDAP Verzeichnisdienst
(fuer User) gekoppelt, und/oder wenn DNS Anfragen für den Rechner besonders teuer sind

BIND kommt erst dann zum Einsatz, wenn die drei aufgeführten Punkte gleichzeitig erfüllt sind!

1. In nsswitch.conf der Eintrag wie folgt aussieht
   

   hosts: dns
   

2. host.conf richtig konfiguriert ist oder nicht vorhanden ist
3. In resolv.conf eine lokale IP Adresse (127.0.0.1 oder die IP eines der aktiven Netzwerkinterfaces) steht.
   

undefined reference to vtable!?

One of the most obscure error message the gcc produces is the output

undefined reference to vtable

The reason is usually simple:

gcc has to put the vtable into an object file. That is the object file, where the definition of the first non-inline member function is. If it is missing, you get this rather unhelpful linker error.
So?! You now have to check the member functions!
