Routing Loops

colin — Thu, 19 Jun 2008 20:42:18 +0000

For amusement value, this is what happens when you have a rogue network engineer who decides to appropriate and advertise an IP network already in use in your enterprise. IP addresses changed to protect confidentiality. AddressA is located in China, Routers A-C are located at WHQ in California, and Routers D-H are located in Europe.

My blog has been sad. I hope that by migrating to wordpress that ease of use will encourage me to do more writing.

I’m 28. It feels like more of the same than any birthday previous.

It’s been a very long time since I had a birthday worth remembering.

2007 Jujo Jiang Invitational

colin — Mon, 22 Jan 2007 06:42:12 +0000

I played in the tournament this weekend in San Francisco. I placed 4th in the 4k-8k division. I tied Karoline Burrall in points (we both had 3/5 wins), but she won the game that we played, so that was the tie-breaker. Prizes in this tournament went down to 4th place; I won $25, which was odd, since it cost me $35 to play. You’d think one would at least win enough to cover your entry fee. But no matter, it was $25 I didn’t have, and I enjoyed all my games except the third, which I lost because I played way too fast. The game against Karoline I lost because of a fighting error that was easily worth 70 points, I lost by 31. A simple extension instead of the clamp I played would have won me the game easily. Frustrated by the loss, I went on to destroy her younger sister, Julie, winning by 55.

In any case, I really enjoy tournament go, it’s great to play with a clock against new & different opponents who don’t play the way my usual opponents do. I’ve played in two tournaments now, and placed in both of them. I hope I can keep that up. ;]

While driving today, I saw a bumper sticker that said Eschew Obfuscation. I silently agreed, but wondered what the point of the bumper sticker was. Then I realized…

Irony.

Nam Ch’i-hyeong

colin — Wed, 20 Dec 2006 08:46:10 +0000

I went to the Sunnyvale Go Club tonight to see the visiting professional, Nam Ch’i-hyeong (another link), from Korea. She is actually a - professor - of Baduk in Korea (Baduk is the korean name for Go). She played a game against Lance Kemper (shygost) even, and won by resignation around move 100, best estimates are that she was already ahead by about thirty points. She played against another dan ranked amateur at 5 stones and won by 14 points. She had to leave, and those of us left sat down and played a few games. I played against someone ostensibly of my own level, and after making 4 or 5 grievous errors, I still won by 10 points. Go figure. (pun mercilessly intended)

I made an assertion not too long ago that what I needed at this stage was not more study, or problems, or books, but just to play many many games to get more experience under my belt. The inconsistency of my play tonight was easy proof of that. Back to KGS.

I’m looking forward to a 4 day workshop starting a week from Wednesday with Yilun Yang (link, link). This is going to be a solid 4 days of go training. I’m very excited.

Go Tournament

Played in the Dote Memorial Go Tournament in San Francisco over the weekend. Came in third in my division. w00t.

In other news, this site is no longer borken.

GRE

Took the GRE today. 610 verbal, 800 quantitative, both out of 800. This’ll make grad school applications a bit smoother. =]

dad

colin — Wed, 02 Aug 2006 07:46:52 +0000

My dad met the kids. Better late than never. I miss him… which is odd because I’m not really sure what I’m missing. How do you miss something you never had? If you’d never seen another human, would you be lonely?

(Am I writing this when I should be sleeping so I can go to work in the morning? I think so!)
