People Behind KDE: Stefan Westerfeld

This week's installment of Tink's People Behind KDE features Stefan Westerfeld, the creator of KDE's multimedia architecture based on aRts. Besides delving into the usual background, Stefan shares his favorite saying: "Software is like sex, it's better when it's free". Amen.

Comments

Now if only someone would tell me why artsd chokes on a stock 7.2 Mandrake after having compiled everything from source (bug reported ages ago) (kernel 2.4.3, again compiled locally):

rubberducky.hall(15)> artsd

I apologize - that had the wrong airs to it as I just posted it quickly. A big thank you again to all developers! KDE has been the first and only thing to get me over from the CLI world!

What? Free software is good, but free sex just sucks. We all realize thet, admit it or not. That's why we know terms like "bitch" and "bastard". Only, there isn't term "bitch" for male. It's unfair, isn't it.

Can Stefan not have just one day? :)


By Charles Samuels at Tue, 2001/04/24 - 5:00am

i'm a bastard inside :-)


By mikka at Tue, 2001/04/24 - 5:00am

Fixed.


By Guillaume Laurent at Tue, 2001/04/24 - 5:00am

That is the most beautiful thing anyone can say about any KDE bug :-)

aRts is excellent! Now all we need is more apps that use it since soundwrapping doesn't work for some of those naughty apps! Keep up the good work.


By Con Kolivas at Tue, 2001/04/24 - 5:00am

It works with realplay, aviplay, xmms and quake.

Of course nobody would play quake with a sound lag.

You just add e.g "artsdsp realplay %u" to the realplayer menue entry and it works as if it were created for arts. IMHO, this should even be the default.


By Moritz Moeller-... at Tue, 2001/04/24 - 5:00am

Try pmfax lite - it doesn't like artsdsp.
Yes I know it's a binary only commercial app. But I want an answering machine and kvoice has been deprecated and no longer works with kde2 anyway.


By Con Kolivas at Thu, 2001/04/26 - 5:00am

Hi!

My name is Alvaro and i would like to work with kvoice in my university. The problem is that i haven’t any information about it. Do you know where could i take a manual? Do you have it?

thanks from Spain

Why is the system bell so slow to react?


By Joe at Thu, 2001/04/26 - 5:00am

Is aRts ever going to be something stable. I did a search on google for aRtsd and found nothing but it not working. I sure do love open source software and Linux and UNIX but sound under KDE or GNome does not work on my stock Redhat 7.2 system. It seemed to work ok under 7.1 but really tore into my cpu and now it just rips into it so much that it crashes.

These are the debug info that I get:

Is there anything that we can do to get it up and running atleast until we get the software fixed?
