Building a Fedora 14 box and thought I’d just keep all my reference links in one place this time. Might be helpful if you’re building a Linux workstation for the fist time (or are just forgetful like me :-).

Tuning Solid State drives in Linux

Intel Sandy Bridge 82579 driver

Fedora 14 Nvidia Drivers Install Guide

Disable SeLinux on Fedora 14

Enable Fire Sharing with Windows via Samba

Hard Disk Clone with “dd” (dd if=/dev/sda5 of=/media/Data/disk1.img).

Maya 2012 Installation works as per Autodesk’s guide, except for having to add the following to Fedora 14 :
tcsh
xorg-x11-fonts-100dpi
xorg-x11-fonts-ISO8859
xorg-x11-fonts-ISO8859
xorg-x11-fonts-75dpi

APCUPSD Manual (for control of UPS’s)

Intel 82579v (Asus P8P67) Fedora 14 Driver Install

nspluginwrapper and flash install

And finally, moving my tempdir to a much larger volume then starting up Houdini (which really eats up the space on big sims!). It will be slower over a NFS mount, but until I get a dedicated cache disk, it will have to do:

HOUDINI_TEMP_DIR=/media/Projects/Houdini/TMPFILES
/opt/hfs11.0.733/bin/houdini

Overclock a Linux box? You’ll want to monitor temps (even if you don’t overclock, it’s a good idea to check every once in awhile).

How to get linux sensors information

The old post was under Ubuntu 10.10 and worked great. For various reasons I’m running Fedora 14 at the moment and configuring this Wacom 2 tablet is just as simple, but is done in a different manner. Though this is based on a SourceForge article, I had to modify things a bit to get it all working:

Create a text file named .xsetwacom.sh file in your home directory and make it executable (chmod +x). Assign it to start up  (system/preferences/startup  through the GUI). The pertinent content for this file I’ve adapted from the documentation page above. Works for me here, though your mileage may vary:

xsetwacom set “Wacom Intuos2 6×8 stylus” Suppress 4  # data pt.s trimmed, default is 4, 0-20
xsetwacom set “Wacom Intuos2 6×8 stylus” RawSample 2  # data pt.s filtered, default is 2, 0-100
#xsetwacom set “Wacom Intuos2 6×8 stylus” ClickForce 27  # pressure, default is 27, range is 0-2047
xsetwacom set “Wacom Intuos2 6×8 stylus” Threshold 27  # pressure, default is 27, range is 0-2047
xsetwacom set “Wacom Intuos2 6×8 stylus” PressCurve 5 10 90 95  # Bezier curve, default is 0,0,100,100
xsetwacom set “Wacom Intuos2 6×8 stylus” TPCButton on  # stylus tip + button, or “off” for hover mode
xsetwacom set “Wacom Intuos2 6×8 stylus” Mode Absolute  # or Relative cursor movement
xsetwacom set “Wacom Intuos2 6×8 stylus” Button1 1  # left mouse click
xsetwacom set “Wacom Intuos2 6×8 stylus” Button2 3  # right mouse click
xsetwacom set “Wacom Intuos2 6×8 stylus” Button3 2  # middle mouse click
xsetwacom set “Wacom Intuos2 6×8 eraser” Suppress 4  # data pt.s trimmed, default is 4, 0-20
xsetwacom set “Wacom Intuos2 6×8 eraser” RawSample 2  # data pt.s filtered, default is 2, 0-100
#xsetwacom set “Wacom Intuos2 6×8 eraser” ClickForce 27  # pressure, default is 27, range is 0-2047
xsetwacom set “Wacom Intuos2 6×8 eraser” Threshold 27  # pressure, default is 27, range is 0-2047
xsetwacom set “Wacom Intuos2 6×8 eraser” PressCurve 0 10 90 100  # Bezier curve, default is 0,0,100,100
xsetwacom set “Wacom Intuos2 6×8 eraser” Mode Absolute  # or Relative cursor movement
xsetwacom set “Wacom Intuos2 6×8 eraser” Button1 1

Hope this helps somebody out there. Tablets are great, if you can set them up to work the way YOU would like.
ps. Just tried this with Scientific Linux. Had to confirm the tablet device name (with a “xsetwacom –list”) and found it quite different. Not only that but the device needed to be wrapped in single quotes to work. And some of the parameters were not supported. It’s a minefield! :-). If things are really not working, just put the -v flag into a config line and run it in a shell. It should tell you what’s broken.

Two Galleries

Two galleries are present now, linked above. One dedicated to Stanley and friends, the other to non-panorama photos out and about.

Touching on a previous post, it seems a combination of Microsoft’s ICE and Hugin is getting me by on the panorama stitching front. Though the flash panorama output of Kolor’s Autopano Giga is interesting me too. I don’t take 360 degree panoramas (yet), but it’d be nice to put them into an environment to “revolve in”. For tone mapping, Picturenaut for more naturalistic tweaking, Photomatix to really ramp things up. Too bad the former isn’t 64 bit.

More of the woods.

Besides Stanley running into the shots, we’ve had a good time during a brief week of sunshine here in Vancouver. The new lens is working well and I’ve actually spent two days shooting with the camera set to manual. Lots of mistakes, but it’s slowly coming together.

This Pano didn’t turn out as expected. I was going for a full set of bracketed exposures to create a proper HDRI with when it started snowing! So much for a pleasant day at the beach. I took this in a hurry, and it shows.
Spanish Banks Starting to Snow.

Sigma 10-20 mm lens.One thing that is slowing me down is my stock lens. With the sensor in my camera making the focal length a little longer, I’ve had to take 15 images for each 360 degree “strip” of the panorama. Not only is this time consuming, but it means I’m ingesting far more data than needed. 27k wide panoramas sound great, but it’s overkill for my purposes. To that end, a Sigma 10-20mm F3.5 EX DC HSM lens mysteriously appeared today. With the wider viewing angle, it means I’ll need far fewer snaps.

Now to take the bracketed exposures more quickly. Right now I can set up the camera to take three automatically, enough for creating “HDRI snapshots” but not nearly enough for technical work. I can do multiple sets of these brackets manually but, well, some other options I’ll be exploring:

…and took some photos. I haven’t shot a panorama in ages, so I thought it time to get back into it again. Canon T2i, stock lens and Manfrotto Pano head. Original is 27,389 x 5430 tone mapped HDR.

I do have a fondness for messiahStudio, having used it since early days. I still animate in it and bring the data elsewhere via MDD. Everything else just seems so slow.

In any case, they’ve got a marketing campaign on where you get the package, pro or basic for a ridiculous price ($40.00 or $10.00), but only if they get enough people signing up.

You’ve got (almost) nothing to loose, and it helps me to procrastinate learning to rig in anything else!  PMG “Dare to Share” $10 Challenge.
