Looking back...
As I look back at code I wrote a decade ago as an undergrad, I often find lots of little things that can be done better. For instance, in one file I found that reversing the order in which two functions were called would have eliminated a half dozen conditionals from one of the functions and would have resulted in the same expected behavior, but with fewer lines of code and a lower cyclomatic complexity.

FreeBSD Unix on Dell Precision M4800
I installed FreeBSD 10.3 on the laptop I recently acquired and almost eveything worked out of the box. The gigabit ethernet and wi-fi coards worked fine and by setting the BIOS to discrete graphics only, the nVidia Quadro was recognized.

I installed the binary driver from nVidia, because they support FreeBSD because they're awesome like that. The nvidia-xconfig(1) program was useful to streamline the process of getting X.org to use the Quadro.

There were a few things that did need some tewaking though. First there's the sound card. Because the quadro supports HDMI (in addition to VGA and DisplayPort), it includes an HDA-compliant sound card. This card is recognized before the primary HDA-compliant sound card in the machine, the one that's actually connected to the speakers.

I did some research and there were some suggestions about using sysctl(8) to control soundcard GPIO pins to connect the nVidia sound device to the speackers but what ultimately worked was using sysctl(8) to change the default primary sound device to the dedicated card. There were a few ways to make this happen but the one I found that actually worked was to place sysctl(8) command lines in /etc/rc.local.

First I found the device I wanted as the default:

mforde@gaz:~> cat /dev/sndstat 
Installed devices:
pcm0:  (play) default
pcm1:  (play)
pcm2:  (play) 
pcm3:  (play)

Device pcm2 was the one I wanted so I added the following lines to /etc/rc.local

sysctl hw.snd.default_unit=2
sysctl hw.snd.default_auto=2

Now when boot completes pcm2 is set to my default and sound "just works" and sndstat shows pcm2 as the default.

I found ACPI support has some weirdness as ACPI support often does. What I found was that Suspend works from console, but resume doesn't... HOWEVER After I start X ACPI suspend and resume work just fine. Normally I prefer to boot into a console and only start X if I really need it, but because I want suspend and resume to work "by default" I've enabled X to start at boot by allowing the xdm console in /etc/ttys.

But this had one last issue. See, when manually starting X, I added the -dpi 143 option to get graphics and text to be appropriately sized for my screen. XDM needed to know about this.

This probably wasn't the best place to do it, but I edited /usr/local/lib/X11/xdm/XServers and modified the call to X(7) to add the -dpi 143 option. Now when Xdm loads at start up, the DPI is set correctly.

The function keys for adjusting the screen brightness don't work; however, xbacklight(1) works just fine. Similarly the volume keys don't work but I can adjust the volume quite easily with aumix(1).

I've submitted my dmesg output to NYCBUG's dmesgd repository.

I suppose I've posted this for two reasons. The first is so I have a record of how I eventually got these little things working in case I have to do it again. The second is in case anyone has similar issues with their hardware; if they happen to stumble upon this, it might give them some hints.

2010 New York City Marathon
One week ago, I ran the New York City Marathon. As noted many times throughout this blog, this race was something I've been working toward since December of 2008. This event was the culmination of nearly two years of hard work and dedication. And it was worth every single mile I've run over the last two years.

At 9:40, the cannon was fired and the marathon started. Within minutes, I was crossing the starting line and running over the Verrazano Bridge. Not only was I running in the footsteps of the current world record holder and the first American to win New York in 27 years, I was running in the footsteps of legends.

About three and half hours later, I entered Central Park for the last few miles of the race. I looked around and had the odd sensation that I was home.

It's difficult to put into words the feelings of that day. Despite having completed three sanctioned marathons prior to this day, crossing the finish line was something I couldn't believe I was actually doing.

It was absolutely amazing.

X11 Mouse Cursor Themes
Starting after installimg the binary nvidia drivers on both my laptop (Quadro K1100M) and my workstation (GeForce GT 630) Blackbox was defaulting to a mouse cursor that was suboptimal, a black, notched triangle.

The settings in the Xresources for the mouse cursor theme are honored by XDM at the graphical log in, but when Blackbox or Fluxbox start, the cursor would change to the black notched triangle. TWM honors the settings in Xresources, but TWM is just a little too minimalist, even for me.

But there's a simple fix!

Create a file in your home directory (if it doesn't already exist) .icons/default/index.theme. In this file, add the following lines:

[Icon Theme]
Inherits = polarblue

where polarblue is the name of the X11 mouse cursor theme you wish to use. FreeBSD installs many of the X11 cursor sets into /usr/local/lib/X11/icons/, your Unix flavor may be different. In theory, you can also install new themes of your choosing into ~/.icons/ and use those without the need for any elevated privileges.

Additionally, there's the option of creating a .Xdefaults file in the home directory and adding the line

Xcursor.theme: polarblue

Again, where polarblue is the name of theme you want to use.
