This is an old video; I just found it. I uploaded it to YouTube since you can’t view it on the original DVIDS site. When I was in Iraq our unit commander’s (CPT Callaway) mother sent a bunch of toys over to us. We took these toys and handed them out to Iraqi kids.

I wonder what this decade (alright, I know it technically starts in 2011, but still) is going to be like. I hope there’s better music for one. At any rate, a whole set of new experiences and new memories; the last one wasn’t short on that! Here’s to another great decade!

Note: This post shows up on December 31^st because it isn’t New Year’s yet in Arizona (and this blog runs on MST)! I’m in India right now and it’s January 1^st, 2010 here.

She said, “Yes”. Although I guess it was never in doubt that she would say anything else (being a semi-arranged marriage and all), it still feels nice . The official engagement ceremony was today. It was a traditional Nair engagement ceremony (known as a nischayam – literally translated, “decision”) where both families express their consent to the alliance and inform everyone in attendance of the same. I don’t have pictures of the ceremony on me; I’m waiting on the CD of photos from the photographers. This picture is from when I first gave her the ring.

Looking back I think I can say that I’m satisfied with my career. I still remember coming in as a 19-year old Private… I knew that I at least wanted to make Sergeant before I got out, and I’m glad that I was able to achieve that. Being able to wear the uniform is something amazing. You are a part of something larger than yourself. It’s hard to put into words… I just know that it’s something that I will miss terribly.

I can’t say that I’ve looked forward to this day (although my family has). 9 years is a long time to serve and after doing something for so long, it becomes a very integral part of you and your identity. I guess I will always be a soldier and a veteran; I have earned that right. But I know I’ll always be looking back at my Army years fondly, half-wishing I was still wearing the uniform and still serving the nation.

Go Army! HOOAH!

Our Sun is a yellow dwarf star (more precisely known as a G-type main-sequence star), and doesn’t have enough mass to undergo a supernova explosion (type IIa). You need a star that’s at least nine times the Sun’s mass for a supernova explosion. If we’re simply looking at a nova (type Ia), then the Sun doesn’t have a companion to draw matter from when it turns into a white dwarf. So no matter which way you look at it, the Sun is not going to blow up. It’s just going to be really, big and red and will eat the Earth. Unless the Earth moves outward due to the Sun losing mass. Finally the Sun with eject its outer layers and turn into a white dwarf. See? No blowing up. I don’t know why some science fiction authors still talk about the Sun “going nova”. Maybe it’s because it sounds more dramatic.

If anyone has read a science fiction story (or seen a science fiction movie or TV show) that talked about the death of the Sun/Earth and did so realistically, then let me know.

HOOAH! Go Army!

Everything seemed fine. Furthermore, this problem seemed to be limited to both my FreeBSD servers. My Linux box seemed to be running fine. I tried a bunch of things. I restarted both machines, restarted the network interfaces, made sure firewalls weren’t running, reset my router… nothing seemed to work. Every time I tested the connection to the machines (using this awesome tool here), the connections would time out. What was even stranger was that a netstat showed connections to be in a SYN_RCVD state, which meant that the box had accepted the connection. It’s just that the response wasn’t getting out. Eventually I was so desperate that I decided to reinstall FreeBSD on one of the machines. I also posted to a BSD forum asking for help. I figured that next evening I could probably fix it after work.

Well, next morning I still felt terrible, but it wasn’t so bad. My throat wasn’t hurting as much and I didn’t have that much of a headache so I was able to work from home. Oh, and the installation had completed. I set everything up quickly and gave it a whirl. Nope. Same problem. Yeah, I was getting pretty frustrated and annoyed at this point. I went so far as to contemplate wiping my beloved FreeBSD off both machines and putting Linux on there. I updated my post at the forum and I checked on it periodically throughout the day as I kept working. Finally, a kind soul popped in to help me out. He helped me troubleshoot using tcpdump and I was able to confirm that the machine was responding to the incoming connection, but it wasn’t going out. Finally, he asked me to check the routing information. I’m not that well-versed with that so I didn’t see the problem until he pointed it out. The routing information was all wrong!

See, I have two network interfaces on the box. One for my internal network, and one pointing to the outside world. The one pointing to the outside world is statically configured, whereas the one for my internal network picks up its configuration from my AirPort Extreme router. What was happening was that dhclient was overwriting the route information. So when the machine tried to respond back, it saw its default route as the internal router, and not my modem! I had to update my dhclient.conf and force the router address to the correct one:

backoff-cutoff 2;
initial-interval 1;
retry 10;
select-timeout 0;
timeout 30;

interface "vr0" {
   supersede routers 209.x.y.54;
   supersede host-name "enterprise";
   supersede domain-name "xxxx.xxx";
   request subnet-mask,
           domain-name-servers;

   require subnet-mask,
           domain-name-servers;
}

The important line here is the one that says supersede routers 209.x.y.54; (I’ve hidden the actual numbers from teh hax0rs). This tells the dhclient to override the router information that it gets from the DHCP server. Once I did this, everything started working again. My thanks to jggimi at DaemonForums!

Five years ago, I made a similarly introspective post and I wondered where I would be five years from then. Well, so here I am. 27 years old… almost 28… I’m a veteran of a war and I’m finishing up my military service, I’m a citizen, I’m gainfully employed at a job that I absolutely love, I still own a house and a car, and finally, last but not the least, I have found that special someone I’ve been looking for my entire life (and let me tell you, she’s AMAZING). There were many times during the last ten years that were hard for me… but I somehow got through it all, and actually ended up on top when all was said and done.

Looking back at my early days in this country I laugh at myself when I think of how naïve I used to be. But I guess that’s a part of life and it’s probably something that everyone goes through. All in all, I think I’ve done pretty well for myself. So, here’s to another wonderful ten years.
