    RE: Installing the parrot VM on Meego
    [size=4] I have got the reply from the Parot VM team. The parrot VM can be installed in Maemo. But, they have not tried on Meego yet. The steps are shown in the following links.

    RE: Does the pdflush mechanism still hold?
    [size=4] Linux kernel : pdflush has been replaced by using flusing threads per backing device info (BDI) Let me quote some important points : The article Flushing out pdflush ( [url]http://lwn.net/Articles/326552/[/url]) stated that pdflush has been replaced by flusing threads per backing device info (BDI). quoted :" Jens Axboe in his patch set proposes a new idea of using flusher threads per backing device info (BDI), as a replacement for pdflush threads. Unlike pdflush threads, per-BDI flusher threads focus on a single disk spindle. With per-BDI flushing, when the request_queue is congested, blocking happens on request allocation, avoiding request starvation and providing better fairness. With pdflush, The dirty inode list is stored by the super block of the filesystem. Since the per-BDI flusher needs to be aware of the dirty pages to be written by its assigned device, this list is now stored by the BDI. Calls to flush dirty inodes on the superblock result in flushing the inodes from the list of dirty inodes on the backing device for all devices listed for the filesystem. As with pdflush, per-BDI writeback is controlled through the writeback_control data structure, which instructs the writeback code what to do, and how to perform the writeback. " [/size]

    Installing the parrot VM on Meego
    [size=4] Installing the parrot VM on Meego I think this question is related to softwrare development on Linux Can the parrot VM (virtual machine) be installed in Meego? (Y or N) If it is possible, then we can use java to write Meego apps. [url]http://www.parrot.org/[/url] Parrot is a virtual machine designed to efficiently compile and execute bytecode for dynamic languages. Parrot currently hosts a variety of language implementations in various stages of completion, including Tcl, Javascript, Ruby, Lua, Scheme, PHP, Python, Perl 6, APL, and a .NET bytecode translator.

    RE: Linux SCTP and p2p applications
    [size=4] As I searched from google, i found the EU has done extensive research on SCTP. I think EU wants to build a p2p TV network on top of SCTP.

    Linux SCTP and p2p applications
    [size=4] Linux SCTP and p2p applications Just for fun to ask 3 questions : 1. Why not using SCTP to implement a Bittorrent client? 2. Why not using SCTP to do live streaming broadcast? 3. Why at present no applications based on SCTP (Windows, linux)? See also : But supporting SCTP has to start somewhere ? Why? [url]http://lwn.net/Articles/363696/[/url] [/size]
