  1. 10 things you might want to check out in DP2 on FreeBSD 5.0 Developer Preview #2 · · Score: 5, Informative

    Here are some big ticket items in -CURRENT that you might want to check out.

    1) Filesystem Snapshots/Background fsck - On filesystems with softupdates enabled, fsck will be performed on the mounted filesystem (well, actually a snapshot) after the disk is mounted. This allows fsck to be run without affecting uptime along with the other obvious benefits of having snapshot support (dump comes to mind).

    2) ACLs - Filesystem ACLs are included with FreeBSD now and can be set using the standard setfacl/getfacl methods

    3) LOMAC - The LOMAC with DP2 is apparently old and seems intrusive. A recommendation from the author was to try the version of LOMAC from trustedbsd CVS. It is said to contain "99% less ASS" ;).. Recommended you use UFS2 for full extended attribute support.

    4) MAC - I personally haven't tried it yet, however I plan to. Recommended you use UFS2 for full extended attribute support. This could/should rock :)

    5) GEOM - A modular framework for disk I/O. This allows modules to be placed along the I/O request path in order to do nifty things such as filesystem encryption easily. There is an encryption module already written for this as well

    6) UFS2 - UFS with extended attributes support and various code cleanup afaik. sysinstall will use UFS1 by default ;(.. UFS2 is not yet bootable on i386 due to space constraints in the boot loader. No word on whether this will be fixed in time.

    7) SMPng - Have at it.. Last I heard, the speed increases weren't as significant as people seem to think they'll be. The groundwork is laid out though for future speed improvements. A lot of code has been moved out from under Giant (Big Giant Lock). That could have definitely changed though, as the last time I heard an SMPng update was at the kernel summit in SF. There are quite a few debugging options enabled in GENERIC, so you might want to take note of that.

    8) sparc64/Itan{ic|ium} - If you have a supported hardware config.. Itanium is under /pub/FreeBSD/development I believe. sparc64 is actually part of the DP release

    9) gcc3 - Nothing more to really put here.

    10) New and improved rc system in /etc/rc.d. This is basically an import from NetBSD. scripts in rc.d, as opposed to the init.d/rc*.d method where the filename determines the dependency order, use a program called rcorder(8) to determine the order in which scripts are executed. rcorder determines the order by special headers in the scripts. e.g.

    # PROVIDE: sshd
    # REQUIRE: LOGIN
    # KEYWORD: FreeBSD NetBSD

    Ports, unfortunately, does not use this dependency system yet. However, last I heard, there will be a cutoff date at which time they should support it.

    Some information may be outdated, but most of it should be correct.

  2. Re:Oracle on Apple XServe? on Oracle's GPL Linux Firewire Clustering · · Score: 1

    There is an OS X port of oracle. I'm pretty sure it's a final production version.. but I could be wrong on the status.

  3. Re:Why on Oracle's GPL Linux Firewire Clustering · · Score: 1

    firewire cables are very heavily shielded as well..

  4. Re:battery life on Apple Gives Laptops Speed Bumps · · Score: 2, Informative

    Yes.. you can easily watch a dvd on one charge.. I've done it many times, and I usually have about 30-40% left over afterwards. This is on a TiBook 400mhz. I think they actually have improved the batteries themselves since then..

  5. Re:Buying an apple on Apple Gives Laptops Speed Bumps · · Score: 1

    Well.. Besides the fact that the hardware design isn't bad at all .. The reason is: MacOS X.. 'Nuff said.

  6. Re:MPG indicators on dashboards (got one) on Toyota to Move to All Hybrid Vehicles By 2012 · · Score: 1

    The Honda hybrids (and I'm sure the Toyota does too) have the instant MPG readout. But in addition to that they have MPG readouts for each trip counter. So it gives you an average mpg for each of your trip counters (you have 2 trip counters and one total mileage counter). Oddly enough there is no MPG readout for the total odometer reading although there are for the trips. I agree that the instant ones fluctuate way too much to be dynamic. I hardly ever look at mine.. The CHRG/ASST readout, oddly enough, is the one I look at the most.

    I have a picture of the dashboard up.. http://zope.ods.org/jason/maryland/car9?display=

    The instant MPG readout is in the form of a horizontal bar graph at the bottom of the dash.

    Cheers,
