More than one year later, I finally add an entry to this diary. I am back to the Linux kernel world and I am very glad about that. I will manage to have time to try to solve some challenges in this world and I am already working on some new ideas. So far, the port of compressed caching to Linux 2.6 is not on the top of my list because I want to start working on some tasks that won't take that much of my time. Then, when I notice I will have enough time and knowledge of Linux 2.6, I will get back to compressed caching.

Today I subscribed to Linux kernel and Linux-MM mailing lists, downloaded 2.6.8 and already read a paper about the new idea I mentioned above. Now it is time to read the code and understand some recent discussions I read in the mailing list archives.

The paper I published last year about compressed caching is avaliable on my site.


Today I tested Skype in Linux and it worked perfectly. I was amazed with its sound quality and with the sound quality from a mic that came with a Sound Blaster Live! card that I bought in Canada.


Check the text from the GnomeMeeting site about Skype:

"The main problem is not that the program is not Open Source, the problem is that Skype is locking users into a proprietary protocol. Would you imagine the Internet with a proprietary equivalent to the HTTP protocol that only a given client could browse? That's what happens with Skype. Skype also has a great marketing force, some people even think that Skype has a superior audio quality. How could Skype have a superior quality when it is using the same codec (iLBC) than software like GnomeMeeting while introducing more latency by making calls go through a 3rd party? The only real advantage of Skype is that it is easily going through any type of NAT, using a 3rd user to proxy the call. But the day when the Linux kernel NAT will natively support H.323 or SIP, Skype will have lost its only advantage... Skype is hype..."
