Sum up the values of a function
...roblem is.
I have shorten the code a little bit, so that you only get the
necessary facts:
ws12 <- function (z, i) (1/(1+exp(z[1]*(z[3]-x1[i]- z[4]*(m1[i]/n1[i]-0.5)))))
ws37 <- function (z, i) (1/(1+exp(z[2]*(z[3]-x2[i]- z[5]*(m2[i]/n2[i]-0.5)))))
wsAttack12 <- function (z,i) (ws12(z,i)*dec1[i]+(1-ws12(z,i))*(1-dec1[i]))
wsAttack37 <- function (z,i) (ws37(z,i)*dec2[i]+(1-ws37(z,i))*(1-dec2[i]))
logwsAttack12 <- function (z,i) (log(wsAttack12(z,i)))
logwsAttack37 <- function (z,i) (log(wsAttack37(z,i)))
ws12sum <- function (z)
(logwsAttack12(z,i=1)+logwsAttack12(z,i=2)+logw...

[patch] linux-2.6 performance fix
...onfig more than quadrupled iperf throughput,
restoring the gigethernet network performance to wire speed at long last.
Applies to xen-2.0-testing.bk xen-2.0.bk and xeno-unstable.bk
The throughput on linux-2.4.29 seems fine. I hadn''t tried it since 2.4.27.

[Fwd: Re: [Fwd: failure delivery]]
...quick solution for a
forecasting task I'm doing.
I have been modelling some retail sales data, and the days just after
Thanksgiving (US version!) are important. So I created some dummy
variables by a factor called "events" and (really ugly!!) have TG, TG+1,
TG+2, etc. Now I also have DEC1, and the calendar and data are such
that in the period I'm forecasting I have TG+3 but this is
NOT in the estimation data. There are also weekday factors (wdf) and some
cross factors (Saturday + some special days is highly significant).
The model is Sales ~ daynumber + wdf*events + wdf*speci...

Demo in rails2.pdf of add_price migration, PostgreSQL 8.1.4
People,
I''m looking at the migrate example on p 74 of the rails2.pdf
It''s a simple example of using a migration to add a column to
the products table.
Here is a copy of the migration file named 002_add_price.rb
after I generated and then edited it:
class AddPrice < ActiveRecord::Migration
def self.up
add_column :products, :price, :decimal, :precision => 8, :scale
