    I admire your patience and persistence! But for those who don't feel like arguing with lawyers and clerks, I suggest the "stupid pc user" approach I described. Anyhoo, best of luck with your laptop synack

    [Linux] Emacs + cscope

    Dear Aijaz, Unfortunately I don't know enough about Emacs to help you but I think you 'll find the following link really helpful for your studies until you figure out how to properly configure Emacs; it's what I'm using nowdays to study freebsd kernel code. http://fxr.watson.org/ happy...

    freebsd burning out a laptop screen.

    Not quite. Here in Greece sometimes it's part of the Warranty/License agreement that comes with your laptop and states something like "if you install any other OS, besides the stupid Windows Vista that your laptop came with, the warranty is nullified" And on that ground they can refuse to fix...

    Install FreeBSD along witht the existing Windows partition.

    Start a new thread and state a specific question. There are a lot of experienced people here to help you but no one will answer a vague question like that with anything but a link to an online manual/tutorial. Also, try googling because you can find a lot of articles on how to dual boot...

    Install FreeBSD along witht the existing Windows partition.

    About cromwellot's latest question: AFAIK EasyBCD doesn't work on Windows XP, you need vista or win 7. The easiest answer to your question is to choose the "None" option when installing freebsd and then configure grub from your linux partition and add the freebsd partition to grub. As I...

    Writing a scheduler

    Questions concerning the low level implementation of the kernel are better addressed at the hackers mailing list. I'll give you enough to get you started though. Take a look at /sys/kern/sched_4bsd.c and /sys/kern/sched_ule.c These are the two schedulers you 'll find in fbsd, ule is used by...

    Radio Streams

    I tuned in twice the other day to that "hacking" radio and the first time, they were discussing something about restaurants and the second time there were two guys and a girl going on and on about pirates vs zombies and that emo vampire from twilight. I felt my intelligence going down just by...

    Debian + FreeBSD 7.2 Kernel - Benchmarking Debian's GNU/kFreeBSD

    I concur, the wiki page that lists the reasons why someone would choose Debian kFreeBSD over FreeBSD is -to put lightly- a joke. Let's wait and see what will happen, although I have my doubts if this idea is going to work out and attract a lot of users.

    FreeBSD Kernel Internals - Video Lectures (Any experiences?)

    Hi there! I have not watched these videos but I believe I can answer the second half of your question. First of all, you have taken a look at danger's post, right? I am currently studying the FreeBSD kernel myself so I can tell you what works for me. 1) Take a look at watson's post...

    Limits for FreeBSD jails

    AFAIK such functionality has not yet been implemented. Besides the man page & the handbook that you have already checked (i think), check the wiki page: http://wiki.freebsd.org/Jails There's a patch so you can limit the resources of a jail but it's not yet complete. Cheers

    Tell me I'm blind / clueless but...

    I do believe that you'll be more interested in PC-BSD, it's a fork from the FreeBSD project with casual users in mind and yes it provides a UI out of the box. Check it out http://www.pcbsd.org/

    vm active queue

    Go here http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/vm/vm_pageout.c and check out the vm_pageout_scan function, that's where the magic happens. I do believe however that if the page is being removed atm and the usage counter is zero, you can't tell which thread used to reference it. I don't...

    vm active queue

    Hi! First of all, your question does not make much sense to me. Perhaps your question was "when" does a page gets removed from the active page list or perhaps "where" does that page go to when it is removed. Anyhoo, I ll try to answer both questions. The OS monitors memory utilization and...
