Alpha
Due to the power failure, there was the loss of several hours of work. Last night I installed FreeBSD 6.2-RELEASE on an old DEC AlphaStation 200 I have. I had started building a new, smaller kernel for it around 23:30 last night. It had not completed by the time of the power outage. I have restarted that build.
Any one reading this would reasonably ask, "Why are you not as confused/angry/annoyed with a compile that was not finished in 7 hours as you were about one that took 3 hours?"
The answer is simple. This AlphaStation is powered by a 100MHz DEC Alpha EV4 CPU and has 64MB of RAM. To the best of my knowledge, DEC made this machine around 1994 or 1995. I expected the build to take a long time; the machine is around a dozen years old.

Tenth Runniversary
Today is my tenth runniversary. It's been a decade since I first stepped on that treadmill. Like my first day running, I ran on the treadmill while listening to br\oken. I've had some set backs in my recovery. Not properly rehabilitating the atrophy in the left leg has caused some problems with the muscles around my hip. Listening to my trainer only made it worse. But now I'm taking care of it properly. Like that first day ten years ago, I have a goal I am working toward. This time it is the Dublin Marathon in October. This will be marathon number 13. I don't expect to PR. I think 10 minute miles are a much more reasonable goal at this point, but frankly I'll be happy just to cross that finish line. It's been a long, hard road out of Hell, but God has been by my side and put some amazing people in my life to help me along the way. I have to thank the Giraffes for today. I have to thank the Giraffes for much of my life this last decade. I was heading for an early grave, and they changed that. Giraffes, I thank you from the bottom of my heart and I look forward to running the LTC and many other races with you in the next decade.

Take back your privacy
Recent surveys have found that 76% of [the most visited] websites in the world cotain trackers from google and 24% contain trackers from facebook. This has been reported by CNBC, PC World, The Verge, Fortune, and Breitbart.

Almost anywhere you go on the internet, they are following you, building a profile on you, and selling that information, your information, to the highest bidder. Even if you don't have a user account for google or facebook "services," they've built a profile of you using this surreptitiously collected data.

It turns out there are some steps one can take to prevent these companies from following you wherever you go. It's not perfect, but it helps a lot. First, don't use Chrome. Second, install ad-blocker plugins for your browser. Third, use your firewall.

It turns out Google and Facebook are large enough that they have their own Autonomous Systems (AS) composed of numerous subnets. Google owns AS 15169, while Facebook owns AS 32934. Using a little bit of shell, it's relatively easy to look up all the subnets owned by these companies.

whois -h whois.radb.net -- '-i origin AS32934' | grep "^route:" | awk '{print $2;}'
whois -h whois.radb.net -- '-i origin AS15169' | grep "^route:" | awk '{print $2;}'

That's a lot of subnets. Because I have different operating systems on different computers and still want to block traffic to and from all those IP addresses, I've written some simple scripts to add rules to various firewalls. I have scripts for IPFW on FreeBSD, IPTables on Linux, and the Windows Firewall that should work from XP SP3 through Windows 10. I've only tested it on Windows 7 and Windows 10, and it worked in those.

All of these scripts can be found in this directory. The IPFW and IPTables scripts are self-contained. For the Windows command shell batch files, the *ips.txt files are also needed.

I have to say, the internet looks very different with these firewall rules in place. There are noticeably fewer advertisements and pages load faster. Embedded YouTube videos and Instagram photos don't appear. Sometimes the frame disappears, sometimes you get a "failed to connect" page appearing in a frame in the middle of a page. (Yes, these rules block YouTube and Instagram; they are owned by google and facebook and reside in the subnets owned by those companies.) On a relatively rare occasion, I come across a site using some sort of javascript or css or something hosted by a machine in one of those ASs and that will be blocked. Sometimes the site handles that gracefully, sometimes it stops being functional. A small price to take back your life.

Update: Twitter has trackers on a decent amount of sites out there too, so I've added scripts to block Twitter's AS 13414 as well. Those scripts are in the same directories as the others.

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.

Highway driving
On the way to the mechanic yesterday, I had the DeLorean out on 287 South. Near one of the Boonton exits, a guy in old Stingray pulled up next to me on my right. I looked over, he looked at me, and we gave each other a nod. I sped up a bit to keep with the flow of traffic and he moved as if exiting soon thereafter.

This was my longest trip with the DeLorean thus far, and also the fastest I've ever driven it. And no, I still haven't gotten it to 88mph.

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.

Don't Call it a Comeback
On June fourth, I was running in the Tourne on a trail I first ran twenty years ago, a trail I've run hundreds if not thousands of times before. On that morning, my foot came down on a wet rock at just the wrong angle, slipped just enough and I rolled my ankle. Not only did I roll the joint, I came down on it with enough force to break it; a fact I would learn when I final saw a doctor about it on June ninth.

No surgery was required, but I was unable to run for three months. I was finally cleared to run. The plan was to start with short distances, about a quarter mile, on a rubberized track then build up from there, moving on to treadmills and eventually roads and trails. I was instructed to spend six months rebuilding my 60 mile per week base.

On the morning of September 11 (a day I will never forget and a morning that will always make me feel a bit uneasy), I took to the track for the first time. I started by walking a mile. As I finished the fourth lap, I said a prayer, asking God to give me the run I needed and the wisdom to know when to stop. I queued up my playlist: AC\DC's "Back in Black" and LL Cool J's "Mama Said Knock You Out." I took my first stride.

I've been progressing well in the last two weeks; pushing it on some days, resting when necessary. Though the short, slow distances have been frustrating, it feel good to be running again. Every stride I take I'm reminded of everything I love about the sport.

It's good to be back.

If my calculations are correct...
Over the course of the last two years and four months, I've changed considerably both mentally and physically. I lost 108lbs and then put on 6 while marathon training. This 6lbs was purely lean mass (muscle, bone density) and I'm now at about 6% body fat.

Running is known to increase bone density, and the various forms of exercise I use in my training increased my muscle mass as well throughout this transformation. I've been curious to know just how much fat I lost.

If my calculations are correct, throughout this process I lost 123.96 pounds of fat and gained 21.96 pounds of bone and muscle resulting in my current net loss of 102lbs.

Why is this filed under the Running section? Because running was what enabled this transformation to happen.

A couple of things....
First, am I the only one who gets freaked out when seeing a Toyota in my rear-view mirror?

Second, google calculator has failed me. I keep trying to do conversions using Joules and it keeps giving me search results for physics forums with no calculator results. WTF google? WTF?

Optical Illusion
I saw this today. I thought it was interesting.

WTF?
I'm used to guitarists mocking the bass and bassists. It doesn't bother me too much. But this... This irritated me. A lot.
Today at work there was a group of people talking about Rock Band and Guitar Hero 3. None of them actually know how to play intstruments but they claim to be great at these games. They seem to believe this entitles them mock bassists.

• "Oh man, bass is so easy. It's the guitar that's the hard part. Yeah, I'm on expert on the guitar."
• "Yeah, bass is so stupid."
• "So It's me, my brother, and my sister. I play guitar, he's on drums, and my sister sings."
  "what about bass?"
  "My friend just got Guitar Hero 3. I'll make him play bass."
  [Both laugh]
• After making statements indicating this person believes he actually is better than Tom Morello, "After you make Tom Morello or Slash your bitch, they play bass for you."

chdir(2)
So today at work another developer many years my senior, with many more years experience than I, came to me with a Unixy problem.
"When I have a program, how can I have it so the current working directory for all processes it starts isn't the one that it started in?"
"chdir."
"No, I want so that if this process starts something like ls, when ls stats 'dot' I want 'dot' to be the directory that process wants it to be, not the directory that process was started from."
After about 15 minutes of me suggesting chdir while he said that's not what he wanted but then describing chdir, I finally wrote something along the lines of the following

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

int
main (int argc, char *argv[])
{
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/tmp");
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/etc");
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/");
  system("/bin/pwd");
  system("/bin/ls");
  return 0;
}

I compiled that, ran it, showed him the output. He said, "Yeah, that's what I want to do."
I showed him the code.
"chdir does that?"

How long does it take to build a linux kernel?
It has been a number of years since I built a linux kernel. Slackware 9.1 was the last GNU/Linux distro I used before switching back to BSD. Tonight I put together a machine from some old parts (1.2GHz celeron with 256KB cache, 256MB RAM, 20GB hard drive) and installed Slackware 12. I customized a kernel configuration and attempted to build it. I don't remember the 2.4 kernel taking as long to build as this 2.6 kernel. It took nearly two hours. Granted, this machine is fairly old, but 2 hours? After I complete the tasks for which I needed this setup, I'm going to install an older Slackware with the 2.4 kernel and build that. I may also install FreeBSD and NetBSD and build their kernels. I'd like to get an idea how long it takes to compile other kernels on this rig.

Race Against Crime and Drugs
The Hoboken Race Against Crime and Drugs was last night. The Giraffes were split into three three-person teams. Unfortunately, two members were unable to run last night. However, two of the more recent additions to the Giraffes stepped up and joined the race.

My right calf was still sore at the start of the race, but felt better after about a mile. By that point it was too late and I knew I wouldn't PR, but I did fairly well keeping my time under 21 minutes and finishing number 79 of 609.

The team consisting of Brian, Liz, and me did fairly well and placed 7th in overall team competitions with a combined time of 1:13:46. Had our second team not been a runner short, they likely would have done well enough for 8th or 9th place.

Random Running Related Updates
I ran in another 10K in Central Park this past weekend. I took it a little easy but still managed to take a minute per mile off my time from the Homecoming Scotland 10K last month. It's funny how much better you can perform without food poisoning.

I have a 3 mile race in the Financial District tonight. It was supposed to be a 5K, but the course was changed due to construction. I'd like to finish in under 20 minutes, but we'll see how it goes. I'm feeling a little sluggish today.

The Brooklyn Half is coming up on the 30th. It starts in Prospect Park and ends at Coney Island. I'm just shooting for a better time than the Manhattan Half. The weather should be about 50 to 60 degrees warmer for Brooklyn so I shouldn't really have to worry about freezing sweat this time. My pace at shorter distances has improved quite a bit since January so I have that working in my favor as well.

The running team is expanding. We have a new member for the Giraffes. Hopefully we'll be able to get five men and five women for each NYRR race so we can be ranked in the club standings. I don't expect we'd do very well against teams like NYAC or TRD, they seem to be fairly large teams with a lot of good runners, but it would be nice to see the Giraffes in the rankings.

Two of The Giraffes (Liz and I) have finished our 9+1 qualification races and are guaranteed entry in the 2010 NYC Marathon. Two more will complete their 9+1 at the Brooklyn Half.

camaraderie
Over the past few weeks, I've been running longer loops than I used to. While out and about on these loops, I often come across other runners. There are a few who I see frequently, and others I see not quite as often. Some have obviously been running for quite a long time while others seem to be just starting out.

One thing I've noticed is that almost all of these people will wave to other runners as they pass each other. It's like when two motorcycles pass each other on the highway, or when a corvette driver sees another on the road.

There's a feeling on camaraderie; a feeling that, despite having never spoken to any of these people, we share a bond.
