WFB, as quoted by Norman Podhoretz:
.. if there were nothing to complain about, there would be no post-Adamite mankind. But complaint is profanation in the absence of gratitude. There is much to complain about in America, but that awful keening noise one unhappily gets so used to makes no way for the bells, and these have rung for America, are still ringing for America, and for this we are obliged to be grateful. To be otherwise is wrong reason, and a poetical invitation to true national tribulation. I must remember to pray more often, because providence has given us the means to make the struggle, and in this respect we are singularly blessed in this country, and in this room.
And on what WFB considered above all:
I am programmed to love God and to seek, however vainly, to obey him, and to trust that the course he laid out for me in the grandest voyage, through time and space, and uncertainty, to infinity and transfiguration, and resolution, is as certainly charted as the toyland course that will lead me from Miami to the Rock of Gibraltar.
I shall follow the star of Bethlehem, waywardly; and if I fail to reach it, I shall be guilty of every delinquency save that I ever doubted it was there.

New methods for large dynamic range problems in planetary formation
D.S. McNeil and R.P. Nelson
Modern N-body techniques for planetary dynamics are generally based on symplectic algorithms specially adapted to the Kepler problem. These methods have proven very useful in studying planet formation, but typically require the timestep for all objects to be set to a small fraction of the orbital period of the innermost body. This computational expense can be prohibitive for even moderate particle number for many physically-interesting scenarios, such as recent models of the formation of hot exoplanets, in which the semimajor axis of possible progenitors can vary by orders of magnitude. We present new methods which retain most of the benefits of the standard symplectic integrators but allow for radial zones with distinct timesteps. These approaches should make simulations of planetary accretion with large dynamic range tractable. As proof-of-concept we present preliminary science results from an implementation of the algorithm as applied to an oligarchic migration scenario for forming hot Neptunes.

The Man tried to bring me down, and destroyed hundreds of gigabytes of my work, but he’ll have to do better than that.. if all goes well I’ll submit the above paper next week and the first science paper in April!
I named the new method Naoko, after the beautiful supermagician Yamada Naoko. But if anyone asks, I’m going to say it stands for New Adaptive Orthochronous Kepler Orbiter..
happy new year! 1 January 2008

Or, to put it another way: あけましておめでとうございます!
I suppose the time has come to own up to why things were so quiet here in the fall: time that I would have otherwise spent wallowing in enjoyable curmudgeonly gloom was spent studying Japanese. Long story short, I think my geek cred should be pretty well established by now, but I’m about to take it to a whole new level..
To understand the genesis of this we need to go back to the Saturday morning cartoons of my youth– and one in particular, which came on at 6:30 or 7:00 or some such hour: Robotech.
I was astonished. It was a far richer story than anything I’d seen before, and I was completely hooked. I had no defences up against that mixture of romantic angst and battles with giant robots. The background was complicated, the characters were believable, and people I liked _died_. Not temporary back-next-episode deaths, but forever-and-ever deaths. It was terrifying, and wonderful. I used to wake up early just for the chance to watch it, and even after they started playing scheduling games with it I kept getting up in the hopes it’d come back on.
And then I fell in love with the books, written by James Luceno and Brian Daley under the alias Jack McKinney. That’s a minority view, but in my opinion most of their changes were improvements.
I’d long set those memories aside. But then a few years ago, the famous net.writer Steven den Beste stopped writing on his blog USS Clueless and instead started full-time animeblogging at Chizumatic. I followed the transition — he brings a very engineering-oriented mindset to lots of things, and is always worth reading — and wound up deciding it was worth watching some to see if it was worth it. After all, Robotech had been pretty good, right?
So I took his strongest recommendation, and watched Haibane Renmei (灰羽連盟).
I’m not sure I’ve ever seen a better-told short story. The ending affected me more than anything I’d seen or read in a long time.. the only comparisons that come to mind are with the end of Chesterton’s “The Man Who Was Thursday” and Tolstoy’s “What Men Live By”. I felt like I’d discovered a whole new category of good things I hadn’t even imagined could exist before.
That was my re-entry into the anime world. Sturgeon’s second adage famously tells us that ninety percent of everything is crud, and in the case of anime I’d push that percentage closer to three figures. But there are stories you can tell there that you simply can’t tell in any other way. Always and everywhere good writing can triumph.
Which is how I first started casually studying Japanese, and earlier this year I decided to make a more serious go of it. After much individual practice over the summer, I realized I needed more experience with conversation, so I took a class in the fall and it’s been going pretty well (although reading kanji is always going to be a nightmare).
This isn’t just for entertainment purposes, by the way: I’m off to Japan for a few weeks in early summer to visit the planetary group at Tōkyō Tech, thanks to the exceedingly generous offer of Prof. Nagasawa Makiko. They have some of the world’s best N-body planetary astrophysicists there, so it should be enormous fun.
Anyway, there you go. Absence explained!

The best Back-to-the-Future story of the last few days unquestionably belongs to the one and only KenJen.
Come to think of it, he has a lot of great stories, for example:
So, like many of you, I’m sure, I have this huge styrofoam version of my head sitting in the garage. It was part of a parade float here in Salt Lake last July, and after the parade they very kindly called me up and asked me if I wanted the huge head. I said yes. What if I said no and then someday I needed a huge styrofoam version of my head? Then I’d feel pretty dumb.
It’s worth dropping by.
