Building HandBrake on Gentoo, fix for aclocal-1.4 missing error
DVD/ISO to MKV using ffmpeg?:
# export WANT_AUTOMAKE=1.11
# ./configure --force --prefix=/usr --disable-gtk-update-checks
Then run gmake.
Still failing to fully compile (HandbrakeCLI still built though).
Damned python2 scripts that won't run in python3. I'm really hating this incompatibility between versions.

Bug 396537 – app-misc/lirc: compiler driver is invoked with raw linker flags (LDFLAGS)
Bug 396537 – app-misc/lirc: compiler driver is invoked with raw linker flags (LDFLAGS): Commenting out LDFLAGS in /usr/portage/profiles/arch/amd64/make.defaults fixes the problem:
# 64bit specific settings.
CFLAGS_amd64="-m64"
#LDFLAGS_amd64="-m elf_x86_64"
CHOST_amd64="x86_64-pc-linux-gnu"

What a mess...

ZFS scare : state:UNAVAIL , scsi device files changed

or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.

Why did this happen? I have been changing around my disk layouts in the main server, and in doing so the drive order shifted down by two. After much panicing I took a leap of faith and did an export and import.
# zpool export vault
# zpool import vault
# zpool status
pool: vault

Thank goodness.
Now I need to figure out how to convert to import disk/by-id instead of the scsi device file so this non-sense doesn't happen again.
# zpool import -d /dev/disk/by-id/ vault
# zpool status

java - How can I make MS SQL Server available for connections? - Stack Overflow
After fighting with SQL for ten minutes, I finally found the right setting to allow SQL connection over port 1433.
java - How can I make MS SQL Server available for connections? - Stack Overflow: Open the Sql Server Configuration Manager (Start -> Programs -> Microsoft SQL Server 2008 -> Configuration Tools)
Expand SQL Server Network Configuration -> [Your Server Instance]
Double click TCP/IP
Under Protocol:
Ensure Enabled is Yes
Under IP Addresses:
Scroll to the bottom and set the TCP Port under IP All, (Blank by default, set to 1433)
Find the IP address you want to connect to and set Enabled and Active to Yes

[ubuntu] Upgrade to 11.10 broke r8169-based wired ethernet when I reboot to Gentoo
[ubuntu] Upgrade to 10.04 broke r8169-based wired ethernet (working only at 10Mbps) - Ubuntu Forums
What the heck? I was running Ubuntu 11.10 for the past two weeks and I go to reboot into Gentoo and my wired network no longer works!?! Found this post and another talking about shutting the system back down, turn off, unplugged, clear remaining power, and wait couple of minutes and plug back in. Well tada it worked, now what in the world did Ubuntu do to my onboard r8169 cards??

70-200mm AF-S VR II Lens Review by Thom Hogan
70-200mm AF-S VR II Lens Review by Thom Hogan: Which brings us to VR and tripods. Once again Nikon's manuals seem to be causing some confusion. The manual is explicit: "When the lens is mounted on a tripod, set the vibration reduction ON/OFF switch to OFF." Of course, the next sentence starts the confusion: "However, set the switch to ON when using a tripod without securing the tripod head, or when using a monopod." This one is tricky. If you're a tripod on something that has vibration in it (like the deck of a cruise ship), you'll need to be in Active VR, but otherwise you want to be in Normal VR.
Some other sections of the manual will have scratching your head. For example, the description of Normal versus Active VR says "In this mode [Active], the lens does not automatically distinguish panning from camera shake." Okay, so if you're panning on a tripod, you should be in Active mode, right? Probably not. You don't want the VR to fight your panning, only to correct the motion in the axis you're not moving.

ZFS, Where have you been all my life?
Well, I've made the jump. Created a raidz2 (dual parity) pool using the 6 disks I've been testing lately. Transferred 4TB to the system, and now running my first scrub!
sudo zpool status
pool: bigpool
state: ONLINE
scan: scrub in progress since Thu Mar 1 07:06:02 2012
64.6G scanned out of 4.22T at 73.3M/s, 16h30m to go
0 repaired, 1.50% done
config:
NAME STATE READ WRITE CKSUM
vault ONLINE 0 0 0
raidz2-0 ONLINE 0 0 0
sdf ONLINE 0 0 0
sdg ONLINE 0 0 0
sdh ONLINE 0 0 0
sdi ONLINE 0 0 0
sdj ONLINE 0 0 0
sdk ONLINE 0 0 0
Now I have to admit, 73 MB/s is what I'll call slow considering the speeds I had been seeing in my tests, and the fact I'm running across two eSATA controllers ( 3 drives each ), however, the speeds are going up everytime I check the status:
scan: scrub in progress since Thu Mar 1 07:06:02 2012
85.5G scanned out of 4.22T at 75.3M/s, 15h59m to go
This tracks a hell of a lot slower than my RAID controller's RAID-6 array surface scan.
I'll do some i/o tests later. Did a dd read of a 500MB file for a quick test:
532132088 bytes (532 MB) copied, 5.10293 s, 104 MB/s
Not bad, not shocking though.
