JEos- JNode e-Co System

all JNode friends,
We are very happy to declare that we started a new e-Community structure for JNode Researchers.

Welcome to JEos

We need comments,Help from everybody for making JNode as a Next Gen Hero Smiling

mk-Tools on JNode- mkjfat

The JNode based JFAT formatter now working on JNode.Primarily it is working as the Quick Formatter technique.The Command for formating a HDD with JFAT is as :

  • jnode\>mkjfat -c [1|2|4|8|16|32|64] hdb0

  • mkjfat- It is the command name.

  • -c - Specifying the Cluster Size.Here,1 stands for 1KB.2 for 2 KB.
  • hdb0-The Partition Name going to be formatted.

    1)Supporting to the Deep Formatting.
    2)Supports to the FDD,RamDisk,and Flash ROM(hence the
    USB Properties enhancement is going on).
    3)Adding the mk-(EXT2+NTFS+ISO9660) support.

  • High Performance VM integration in JNode

    To make JNode VM level as a High Performanced VM we need to bring a Huge changes in it; more new Experiments in it now require for making it stable.running it in more Low Memory
    it is real chanllenge:::
    I'm seriously considering replacing/rewriting our VM by JikesRVM. I want to share the reasons for doing so and the problems I'm encountering/expecting(during studying the Research papers of JikesRVM).

    First of all the reasons:
    - Writing a good & fast VM is a difficult process which takes a lot of time.(Thanks to Ewout here)
    - RVM has compilers for both Intel & PowerPC
    - RVM has both baseline & optimizing compilers(as the research papers are saying).

    Steps for JNode in JNode

    Here we now start to keeping track about building JNode within JNode.It is a really interesting task for Jnode development process.It will give JNode more Bugs Fixing,more functionalities.
    We need some useful tools for the target JNode in JNode.

    1)A Java Assembler:
    We have a JNASM.But not working now for some bugs in it.need to fix them first now.(now i am looking for them; any help is welcome).
    2)ISO Building Tool:
    like the isofs.exe etc that we using now.
    3)Java2ByteCode Converter:
    A javac functional givener implemented by JAVA.
    4)ANT tools:

    The JNode Building Helping DOCs

    This link to the rapidshare will provide you a PDF docs that saying about the Building the Source code in Linux and the M$ Window$.

    This will help to the new comers in Jnode i think.Hence i just written the steps for building the Source code of JNode here in that Docs.

    Thanks to Pip for giving his experience in the JNode site once.
