New PGP Key!
So apparently Evil32 happened. Approximately 24,000 PGP keys were generated that had collisions with the 32-bit short IDs of existing keys. Then someone decided to use those conflicting keys to generate revocation certificates and upload them to the keyservers. Joy.

Though my old keys still work, they were affected by this mass revocation of collsions. I have created a new key which can be found at http://skinnymf.com/~mforde/mforde.asc.

On a related note, if anyone is interested in Key Signing Party, shoot me an email. I haven't been to one of those since college.

Normalcy
I realized that if and when I have children, they will grow up thinking it's normal to have a DeLorean.

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.

Merry Christmas
While the holidays are supposed to be a joyous time, I know and understand how hard they can be for some people. If you're having a rough time over the next week or so and need someone to talk to, feel free to message me. If you're reading this blog, you likely know my email address or phone number.

Aisling at 35
She's still looking good at 35....

Happy Birthday Aisling!!!!
My DeLorean, #5333, was built in October of 1981. This month, the car will be 35 years old and she looks and handles like the day she came off the assembly line.

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.

Fun Conversations
The DeLorean often leads to conversations one wouldn't normally expect. Case in point: today I had to call my auto insurance provider for an issue with my daily driver. After taking some info to pull up my account the conversation went something like this:

Agent: Which car is this?
Me: The Pontiac.
Agent: Am I reading this right?
Me: Reading what?
Agent: I'm sorry, do you have a DeLorean?
Me: Yes.
Agent: I never thought I'd see someone with a policy on a DeLorean.
Me: Well, you've insured both of mine...
Agent: You've had two DeLoreans?
Me: Yes.

At that point there were a few more questions and then we got back to the issue which my phone call had been about originally.

Trouble opening aterm in FreeBSD?
Here's a soltuion! https://forums.freebsd.org/threads/44941/

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.

Megapath sucks
Speakeasy was by far the best ISP I ever dealt with. Freindly, and above all, knowledgeable. Since they have been purchased by Megapath then merged into Global Capacity, their tech support has been, frankly a bunch of idiots. Furthermore, their website routinely has "Service failed" errors that prevent you from logging in, changing passwords, and viewing account information.

Today, after being unable to log in to the website due to "service failed" the tech support rep on the phoned didn't understand what a subnet mask or gateway address were. Eventually I just got her to read me "all three IP addresses" on the screen in front of her.

But at this point my only other option is Verizon. So I'm sticking with Megapath.

Remapping Keys in Vim
While I love the keyboard on my relatively new Dell M4800, I'm not particularly fond of the placement of the Page Up and Page Down keys to the left and right of the Up arrow, and above the Left and Right arrow keys. I find myself accidently hitting those keys too frequently while editing code and jumping all over the file.

So I remapped them. It was quite simple, because Vim is awesome. I added the following lines to my .vimrc file:

map <PageUp> <Up>
map <PageDown> <Down>

This turns Page Up into a second Up arrow, and Page Down into a second Down arrow. For now, I'll leave it like that. I may remap them to the Left and Right arrows in the future. Or not.

How to Make VMWare suck less Tip #273
Find the .vmx file for your VM and add a line

bios.bootDelay = "15000"

That gives you 15 seconds before the virtual machine launches the boot loader, giving you plenty of time to do things like change the boot order so you start from a recovery CD.

Prince
I'll never forget the day I started liking Prince's music. I was with my friend in his car headed somewhere. We were listening to K-Rock and they had a "listener playlist" where for about an hour, all the music had been selected by a listener and this listener was on the phone, talking with the DJ about his selections and introducing songs.

The guy announced that the next song was from Prince. The DJ questioned this selection and he said, "No, this dude can shred. Just listen."

And we laughed.

And we listened.

And Prince shredded.

It's been a while...
It's been a while since I've had a substantial update here. I've been busy living life leaving little time to be writing about it; at least writing about it here.

Work has been quite busy for a while now. Lots of projects, lots of deadlines, lots of extra hours. But there hasn't been any "mandatory seven day work weeks" like I had at that one job, and there isn't that expectation of "you can work from home so you are always expected to be working" I had at the last job. Plus, the work is a lot more interesting than anything I've done in years.

Bernstein was right: money doesn't motivate me, interesting problems and the ability to tinker do.

Yesterday the DeLorean rolled over to 16,000 miles. That's still about 1,000 miles a year I'm putting on it. I'd like to keep the mileage low, but she's just so much fun to drive. I've been asked by people at work to bring Aisling next week for Bring Your Child to Work Day. Apparently a lot of my co-workers have told their kids about the car and they want to see it.

I ran my 29th half-marathon this past weekend. I'd like to get up to 32 this year. I'm also signed up for my 13th marathon this Autumn. I'm considering running number 14 a few weeks later.

In addition to all of that taking up my time, I've also been volunteering with the Youth Ministry at a church in my diocese. That's been quite an amazing adventure. It's had a profound impact on my life and has certainly helped at least a few teens. It's been an honor to do the Lord's work. Maybe someday I'll publish some of the talks I've given. The In His Image talk seems to have resonated with a lot of people, certainly more so than some of the other talks.

I guess that sums things up for now.

Thoughts on National Computer Science Education Week
This week is apparently National Computer Science Education Week. Code.org is organizing the "hour of code" to promote teaching of Computer Science and Programming in schools. They're also organizing petitions to make CS courses count as credits in Mathematics or Science for High School graduation requirements.

In High School, my CS courses were by far my favorites, Programming in Pascal, AP Comp Sci in Pascal, Programming in C++, and AP Comp Sci in C++ ( the language for the exam switched my junior year). I learned a lot about structured code, elegant, efficient code. I learned enough about Data Structures and Algorithms that I didn't have to study for my college CS classes until Computational Structures (Discrete Math II with Scheme, essentially) in my third semester. I had an amazing Computer Science teacher who also taught me Calculus and the proper order of precedence in life: God, Family, Math. I wouldn't be where I am today without that educational opportunity I had in High School. I want others to have that opportunity too.

However, this is where I differ with the opinion of the Code.org folks. I do not believe that CS classes should count toward the Math or Science requirements. In this state, CS counts toward the "practical or performing art" requirements, I'm assuming under the "practical" label. I think this is a better place for it at the High School level.

Computer Science is not a hard Science. It's not Physics. It's not Biology. It's not Chemistry. There's a saying that if the subject has science in its name, it's not really a science. That is true with Computer Science. It's not studying the how and why of atoms, of molecules, of living systems, of anything really. It's not science.

Computer Science is really applied mathematics. I am very fortunate that the college program I went through was very strong in mathematics: Calc I and II, Linear (Matrix) Algebra, Discrete Math, Discrete Math II in the guise of Computational Structures, Probability and Statistics, Theory of Computation, Algorithmic Analysis... the list goes on. All of these mathematical foundations were then applied to a machine, to make the machine carry out a task in an efficient manner. It's those mathematical foundations that are the true core of Computer Science.

While mathematics is the core of Computer Science and Computer Science is essentially applied mathematics, I do not believe it should count toward the Math requirements. The CS classes would likely detract from other mathematics courses such as Geometry, Trigonometry, and Calculus. These courses are far too important to an education to be replaced by a Computer Science course. Many, maybe even most, High School Computer Science courses focus more on "programming" than the fundamental mathematical theories. They will pick the language du jour and teach you the syntax and semantics. They'll teach about basic data structures like arrays, and linked lists. The AP exam currently focuses not on implementing lists, trees, stacks, queues, and sorting and searching algorithms, but on arrays and lists using Java library calls. This is not math. This is learning Java syntax.

... On man pages, a mini-rant
I really despise the linux man pages. They're useless at best and wrong at worst.

From the man page for setsockopt: "The include file <sys/socket.h> contains definitions for socket level options, described below."

1) The options are not "described below."
2) No, that file actually doesn't contain those definitions.

On the other hand... The FreeBSD man page for setsockopt does actually describe the options and under FreeBSD the <sys/socket.h> file does indeed contain the definitions.

Problems with loader.conf

First the background. The story of how I got into this mess:

I'm trying to get ACPI working on my laptop under FreeBSD. Specifically, I'm trying to get Resume to work properly. Suspend works, and resume seems to partially work. The fans spin up, the keyboard's backlight comes back on, but no screen. And without video, it's a little hard to figure out what's going on.

ACPI works great on my server. It's running the same FreeBSD 9.1 x86-64 build that the laptop is, but the biggest difference is that it's an intel motherboard. The laptop is an Alienware, for our purposes, I might as well just call it a Dell.

I started comparing the ASL output from both machines and noticed some things. First, the Alienware's ACPI implementation looks for the OS to be various forms of Windows or "Linux." The intel ACPI implementation also looks for these Windows variants and "Linux" but it has an additional OS string. It has an entry for "FreeBSD."

I figured the easiest next step was to use iasl co compile the intel ASL source and load that DSDT onto the laptop.

I calculated the odds it would work vs the odds I was doing something incredibly stupid... and I went ahead and did it anyway...

I compiled the asl and I set /boot/loader.conf to override the DSDT with the intel one I had just compiled and I rebooted. At first everything was good. The machine went down, I got the boot loader, and the FreeBSD kernel started to load. Seconds into the kernel load, it rebooted itself. After the second time, I powered off and tried a cold boot. Same problem just as I had feared.

Now i was in a situation where I couldn't successfully boot because of an error in loader.conf I needed to find a way to edit it.

And here's the solution:

The FreeBSD bootloader, like many others, works in stages. At a certain point, it can be interrupted at which point it provides a set of simple yet powerful commands to control various aspects of the loading process. If you still have that default menu at load, I beleive the option to chose is 6. I disable that menu so during a brief countdown I hit escape before the boot loader turns control over to the kernel.

Once in the boot loader prompt, I entered the following commands:

unload
load kernel
boot

Pretty simple right? The unload command does what it says, it unloads the kernel and any modules loader.conf had pulled into memory. The load kernel command grabs the kernel and loads it into memory... but only the kernel thus ignoring the broken DSDT in loader.conf. And of course boot tells the boot loader to continue booting the system.

Once booted, I removed the bad DSDT from loader.conf.

chafing...
WARNING: possible TMI

Why do I run?
So, why do I run? Here's one reason:

[/running] [permanent link]

Windows 8.1 in Virtual Box
I was attempting to run the Windows 8.1 Preview in a VM using Sun's Oracle's Virtual Box on a Windows 7 host. I ran into a minor problem.

The OS wouldn't boot. I received an error stating:

Your computer needs to restart. Please hold down the power button. Error Code: 0x000000C4 Parameters: [redacted]

Looking for the error code online led me to this article describing the issue and a fix. The key to fixing this was running the command:

"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "" VBoxInternal/CPUM/CMPXCHG16B 1

The CMPXCHG16B is an instruction in 64-bit X86 processors that allows for atomic operations on octal words.

Excluding directories while using pax(1)
My primary disk is failing. There are large segments that are generating low level IO errors during read or write operations. Most of the files written to the bad area were under /usr/ports/ where the FreeBSD Ports collection is installed. A few files were under the web server's root.

Figuring I'd take care of things prior to the disk actually failing to the point of it being irrecoverable, I purchased a new disk early. I installed it, partitioned it, and formatted it.

To copy the data over, ignoring the areas that were causing the IO errors, I used mv to "move" the files from the web root under /usr/ports and used the following command as root:

pax -rwvpe -s':/usr/ports/.*::gp' -X / /mnt/newdisk/

The -X prevents pax from traversing into mount points that have a different device ID than the one on which it was started. This prevents an infinitely recursive loop from happening when the new disk's mount point would have been hit. It also prevents data on the non-failing disks from being copied as well.
the -s option allows for sed search and replace scripts to be run. In this example, the : is used as the delimiter and any path matching /usr/ports/* is replaced by a null string. With this replacement all directories under /usr/ports are excluded from the copy.

Christmas Eve
On Christmas Eve, I headed out around 7:00PM to take a look at the Christmas lights and decorations around town. There was a snow storm predicted for around 9:00PM, so I decided to take the DeLorean out for one last drive before the Wonderful Winter Weather(TM).

The snow started much earlier than expected. The snow was light and slow, and despite the car not handling well in slick conditions, I kept going for a while.

As I was driving I had the realization that I was having an experience no one else in the world has ever had. I was driving a DeLorean through my town on Christmas Eve, admiring Christmas lights and listening to Christmas music as snow fell.

I looked over at the empty passenger seat and wished there had been someone, anyone there to share this with. So for now, until circumstances like this arise again, I will continue to be the only person to have experienced this.

When I got home, I took this photograph.

Happy Birthday

I'm starting to get used to celebrating my birthday at TBM concerts. This year it was about a week prior to my birthday at a show on December 1 held at New York's Gramercy Theatre.

Along with the tickets, I had also purchased the "VIP package." This package included an autographed poster signed by all members of the band, a "VIP" laminate on a lanyard, and... the opportunity to meet the band prior to the show!

You may be thinking, "But they stick around after shows and mingle with their fans anyway," and "You've already met them a few times!" Both are true. And even with this "VIP" package meet-and-greet, they still make time for all their fans after the show. What this provided was a somewhat quieter meeting in a more intimate setting.

In fact the meeting was in a small lounge beneath the concert hall. Dim mood lighting, mirrors, and couches set the atmosphere. I spoke with Rainbow, Michael, and Nate first. Rainbow informed me his name was Michael also and made a joke about the "power of the three Mikes lighting the room." After a bit, they started moving me to Chibi who was sitting on a couch after injuring her knee during a show two nights prior. She tried to walk to me, but I told her not to. She said, "I'll meet you half way then."

I gave her a get well card, knowing she had had surgery on her vocal chords about 8 weeks prior and recently injured her knee. Someone decided we needed a photo of that and she gave me the card back so I could give it back to her. I believe it was Owen who said, "Act natural and hold it for 30 seconds!"

I asked Rainbow about writing "Unfamiliar" because both he and OE were given credit in the liner notes. He said it was mostly OE; OE started it and Rainbow had finished it. I said I wanted to thank them because it was a song that had taken on some greater meaning to me and I relayed a brief version of the story of the moment I recognized that. It turns out "Unfamiliar" is one of Chibi's favorite songs too.

Every one of the bands that night were amazing. All, remarkably, were performing as duos. Creature Feature was a real fun band to see. Their music is heavily influenced by old horror movies which gives them a dark yet fun sound.

Aesthetic Perfection put on a good performance. Their drummer is amazing and fun to watch. They heavily synth-based and while there was a dark tone to most of their songs, they still had fun and lightened things up with a Fine Young Cannibals cover.

William Control was the only other act I had heard before the show (Thanks Last.fm!). He was great live and I'd love to see him again. He reminded me a little of Dommin in that Dean Martin meets Glen Danzig sort of way.

The Birthday Massacre was great. They played a good mix including songs from every album. For most of the set Chibi was sitting on a speaker placed near center at the front of the stage, wearing a knee brace. She stood up and moved around occasionally, but not much. At one point Rainbow sat down on another speaker and stuck out one leg in a similar fashion to how Chibi was seated and laughed a little. It was easy to tell by their interaction here that Chibi and Rainbow are close.

If you care (or even if you don't), their set list follows:

• Night Shift
• Down
• Control
• Always
• Red Stars
• Video kid
• Lover's End
• Forever
• Pins and Needles
• Happy Birthday
• Alibis
• Calling
• In the Dark
• Sleep Walking
• Midnight
-- Encore --
• Leaving Tonight
• The Long Way Home
• Blue

The band did not leave the stage prior to the encore as they normally would. Chibi said, "This is the part of the show where we say thank you and leave and you clap and we come back out and play some more. But I'm not going to walk down those stairs anymore than I have to, so do you want to hear three more songs?"

Signs of the Apocalypse
A friend told me this was from Glee. I found it amusing; thought I'd share.

It's a fact that the book of Revelations predicted Twitter. It's one of the seven signs of the apocalypse; Along with porn, unexplainable weather anomalies, martian rovers, Barney Frank, the middle east and MSNBC. It's like Kirk Cameron said, "It's never too late, until it's too late."

I'm attempting to update my laptop from FreeBSD 9.1-Beta1 to 9.1-RC1. The freebsd-update(8) utilitly was reporting an error finding the public key. A quick search found this thread. As per tangram's suggestion, I used

env UNAME_r=9.0-RELEASE freebsd-update upgrade -r 9.1-RC1

and then the update began working.

unHide
After a friend's computer became infected with some malware that hides files in your home directory and tries to extort money from you in order to "recover" your data, I was inspired to write this little program.

All it does is search for hidden, non-system files and unhides them. It defaults to the user's home directory (My Documents), but other directories can be chosen.

If anyone wants to try it out, please do. If you do try it, let me know what parts I can do better. I primarily work on embedded systems and Unix daemons professionally; the user only knows my software exists when it isn't working. As such, I have very little experience with GUIs or human-computer interactions. Any feedback would be much appreciated.

The Windows executable can be found at: http://www.skinnymf.com/~mforde/unHide/. Source code is available upon request.

Fun little alias
I use a console based RSS reader written in Ruby. It crashes often and will delete my list of feeds in the process. It also has a tendency to not fully exit, leaving a ruby process sitting in the background soaking up close to 100% CPU time. For such occasions, I've added the following alias to my .cshrc file.

alias killraggle kill -9 '`ps ax|grep raggle|grep -v grep|awk '\''{print $1;}'\''`'

Just a Question
Given the following code fragment, I was asked to implement foo such that the program would output "America." How would you do it?

        int main()
        {
          char *p = "Hello";

          foo(         );
          printf("%s",p);

          return 0;
        }

My solution involved allocating new memory from the heap to store the new string, and changing p to point to that buffer. They didn't like that answer. They preferred the method of putting the new string in the data segment as well.

I personally would always avoid that, whenever possible. "Hello" is stored in a read-only area of memory as is "America" in their preferred solution. Any attempt to alter those strings will trigger a segfault. This is an accident waiting to happen.

Races, Races, Races
I've been busy the last few weeks or so; I've done a few races.

• On October 30, I ran the Marine Corps Marathon in Arlington, VA and Washington D.C.
• On November 5, I ran the Beavertown Fall Classic 5K in my hometown.
• On November 6, I ran the New York City Marathon for the second time.
• On November 19, I ran the Knickerbocker 60K Ultramarathon in Central Park.
• On December 3, I ran NJ Winter Trail Series Race #1 Half Marathon in Wayne.
• On December 10, I ran the NYRR Jingle Bell Jog in Prospect Park.
• On January 7, I ran the Walt Disney World Half Marathon, part one of Goofy's Race and a Half Challenge.
• On January 8, I ran the Walt Disney World Marathon, completing the Goofy Challenge.

In 10 weeks I ran a 5K, a 6K, two Half Marathons, three Marathons, and an Ultramarathon, plus a few training runs in there...

And last night Wii Fit called me a couch potato.

In defense of the game, I hadn't used it in 547 days, and I'm now 11 pounds heavier than when I had last used it. It has no way of knowing that the vast majority of that weight gain was lean mass. It also has no way of taking into account all that I've done outside the game.
Even with that in mind, it's still a little frustrating to be called a couch potato after running a marathon and a half last weekend.

Each of these races were pretty special. I ran MCM alongside some fairly awesome people; people who I consider to be among my closest friends. In the Beavertown 5K, I somehow managed to take 12th overall and 5th in my age group without really trying.

At NYC and then at the Knickerbocker, I ran with the friend who got me started running in the first place. I credit him with saving my life, and it was an honor and a pleasure to run with him.

The trail half was my first trail race (not counting my time on the high school cross country team) and I ran that with a friend I hadn't seen since our days on the high school track & field team (she was a runner, I was thrower). We have both run full marathons in less time than it took us to complete this half.

The Jingle Bell Jog was a fun race with bells and hot cocoa, and it was the first time I ran alongside my friend and former physics TA. And lastly, I ran the Goofy Challenge alongside another one of my close friends and training partners.

These races were a lot of fun. Some of the courses were quite amazing to see, and these races were opportunities to spend time with some pretty awesome people.

Disgusted
With the Goofy Challenge just 3 days away, I should be carb-loading. And I am. And with each bite of my lunch I hate myself more. Every time I eat, I feel fat. And every time I ingest anything that isn't ultra-lean protein or high-fiber, I disgust myself. But I sit here, shoving food down my gullet.

[/musings/self] [permanent link]

Demo
In the next few weeks we are going to attempt to record and roughly mix a demo of a short track which will serve as an introduction to the album.

Currently known as 11, it is a very short piece in 4/4 time at 80bpm. It is in the key of B minor and the spoken words are taken from a quote attributed to Nietzsche.

What upsets me is not that you lied to me, but that from now on I can no longer believe you.

This short demo will hopefully get me motivated enough to put more time into the album.

More information will be posted when it becomes available.

WPLJ's NYC Half Marathon Themed Phone Scam
Yesterday Scott and Todd aired a phone scam related to the NYC Half Marathon. It's available here for now if you haven't heard it.

I was a little disappointed in the way the guy from the running store responded. He struck me as the kind of guy that looks down on the back-of-the-pack plodders. They're out there doing their best just like the elites and everyone in between; they deserve respect too.

Other than that, it was a rather funny phone scam; one of the best I've heard in a while.

I wasn't born this way; I made myself.
I heard that Lady Gaga song on the radio the other day, you know the one that sounds like the Madonna song, and it got me thinking. On the surface it seems to contain a very positive message about accepting yourself because you were "Born This Way." You were born like this, you were made this way, there's nothing you can do about it so be happy with it.

I disagree. Sure, when we're born we're stuck with the genetic material passed on to us by our lineage. But we're more than that, what we are, what we become, is so much more than how we were born. And this made me think about the Incubus song, "Make Yourself." I find the message of that song to be much more positive. While the song has an overt "them vs. you" context, the general theme is one of taking responsibility for yourself and what you become.

Was I born the way I am today? Judging from the direction my life took in the first twenty-six years, and comparing it to the last three years, the answer is no. I was born heavy, weighing in over nine pounds. I grew into a heavy kid. I was always sad and lonely as a kid. I had few friends. I rarely went outside. I never played sports. I watched a lot of TV. I ate a lot. I got heavier. I got sadder. I got lonelier. But I was born this way, right? I should have just accepted it, right?

While I was born heavy, I didn't have to stay that way. It was my own choices that made me into the depressed, obese misanthrope I was. Despite my claims that I was born that way, genetically predisposed to those conditions, I really made myself that way.

And then I decided to change that. I took responsibility for my life. I started exercising. I ran. I ate healthier. I lost weight. I had better relationships with my friends. I started making new friends. I became happier.

Just as I had made myself into what I was, I made myself into what I am today. The key to this change was taking personal responsibility for myself. No longer did I use the excuse of being born that way. I knew I was like that because of my decisions and my actions. I knew through my decisions and my actions I could change. And I did. I made myself.

"If you really want to live, why not try and make yourself?"
