After rigorous battle w/ my oldest son at bedtime, I was ready to return
to do battle w/ the infamous BBands...then, like a wise father, S.
Wisdom stepped in to smooth
the waters. I felt reduced to a sniveling school yard child, having
realized the point moot, and
my religious zealousness silly.
But how can i lay, after a 'paul graham' shellacking?
First, I am not a hacker. I am a professional developer. The libraries
and tools i have
lovingly, and sometimes in obscure low level, ugly, but well commented
assembly, C, and C++,
written underly some of the largest historic time-series data
warehouses, perf attr, risk mgmt, and
modelling / back-testing systems in place today.
Keane has pitted me against several of the established leaders in both
the historic data and
relational model space, and each time i have come out on top. Top in
terse memory requirements,
top for scalability, top for runtime performance by orders of
magnitudes. And of course tops
for hardware requirements. If you want i can send pretty reports saying so.
DMG, JPMorgan, BoA, Goldman, American Century, Fidelity, Putnam, State
Street, Allianz, Dresdner,
the ECB, the Beaureau of Economic Analysis, Haver Analytic, the Bank of
International Settlements
and many others all rely on my unreadable code. And soon the FED will
be migrating their
historic dw's onto my platform as well. Why? Because, i have a clue
what i am doing in the
little space which is my world.
I don't need Graham's rhetoric. I can find plenty of opinions on both
sides of the fence.
So please don't lecture me on being a programmer. I'd rather learn from
your experience and
wisdom in the financial world. Everyone knows who you are. I am no one.
Can you please leave me the paltry dignity of knowing my own profession?
Or must you claim that as well?
R is a language i have only recently begun to use. I do however have
extensive experience with
similar proprietary languages, and understand the concept space /
knowledge domain just fine.
In fact, i have spoken and taught on several occasions at central banks,
i-banks, and the like.
I defer to Dirk for my R lessons. Clearly, he is the resident guru.
I defer to you for the applied finance CS lessons. And steve. And
others who i hope will excuse
my not mentioning each of their names.
So please, lets stop the insanity, and return to you guys teaching me
something...for my own
selfish needs!
thank you, my apologies if i have exceeded the flame limit, all due
respect, and it hurts
when you step on my toes,
-tom
ps - how could perl possibly still exist?

Code is not meant to be understood...that's what comments are for.
( you do comment your code, right ? )
I'll let Paul Graham reply for me:
"Source code, too, should explain itself. If I could get people to remember
just one quote about programming, it would be the one at the beginning of
Structure and Interpretation of Computer Programs.
Programs should be written for people to read, and only incidentally for
machines to execute.
You need to have empathy not just for your users, but for your readers. It's
in your interest, because you'll be one of them. Many a hacker has written a
program only to find on returning to it six months later that he has no idea
how it works. I know several people who've sworn off Perl after such
experiences."
