Portfolio Optimization
Hi,
I'm an R newbie and I've been struggling with a optimization problem for
the past couple of days now.
Here's the problem - I have a matrix of expected payouts from different
stock option strategies. Each column in my matrix represents a different
stock and each row represents the return to the strategy given a certain
market move. So the rows are not a time series of percentage

Why does plot() ignore the data type for axis labels?
Hello,
I was wondering why the plot() command ignores the datatype when displaying
axis labels. More specifically, if the data points are integers then the
axis labels should intuitively also be integers, right?
> x <- as.integer(c(1,2,3))
> y <-x
> typeof(x)
[1] "integer"

The axis labels are 1.0, 1.5, 2.0, 2.5, 3.0 but if the integer type were

Isn''t it possible to stub / expect on :id ?
Hi all !
Running this:
@payout = stub_everything(:id => 141)
Payout.stubs(:find).with(@payout.id).returns(@payout)
Generates this warning:
./test/functional/payouts_controller_test.rb:22: warning: Object#id
will be deprecated; use Object#object_id
What am I missing ? :id is a fairly frequent method to override in
Rails-based applications.

Might be of help to someone
Hi there,
Last week I got load balancing working between our 2 lans and 2 adsl connections. This script here is how I set it up. A tad excessive stipulating the eth setup at the beginning, but I wanted it all in one script. The firewall config was more taxing, but it is perfectly possible to allow incoming services on either ISP connection and route it back over the correct one, just need to write

There might be something wrong with cv.lm(DAAG)
Hi, everyone
When I was using cv.lm(DAAG) , I found there might be something wrong with
it. The problem is that we can't use it to deal with a linear model with
more than one predictor variable. But the usage documentation
hasn't informed us about this.
You can find it by excuting the following code:
xx=matrix(rnorm(20*3),ncol=3)
bb=c(1,2,0)
yy=xx%*%bb+rnorm(20,0,10)

Any sense of when V1.1.3 might appear?
It's been a month since 1.1.2....I'm about to do some V1.0 to V1.1 move work and
I'd rather start on the curve instead of behind it..........

What might affect keyboard input in a game under Wine?
Hi everyone - and I apologize in advance for the vagueness on this one.
I recently installed Ubuntu 11.10 64-bit (fresh install).
One game that I normally submit test data for has suddenly lost the ability to type. I can no longer enter a userid or password on it's login screen. (I was able to do this in 11.04 64-bit with Wine 1.3.29.) The only keys that are responsive now are the return and

what might cause iSCSI connection 1:0 error ISCSI_ERR_CONN_FAILED
Hi,
I do have a centos 6.x server which accessed two different iscsistorages
for a long time without any trouble.
The storage-connection is done by a separate NIC and VLAN. The LAN
access is on an other NIC.
This weekend something broke and I don't have any clue what might be the
problem or what caused it.
The storages where mounted RO.
In /var/loge/messages there are lot of messages; so

Another thing it might be nice to fix in CELT
Hi,
Bjoern's solution of adding the line:
#pragma intrinsic(_BitScanReverse)
after the:
# include<intrin.h>
worked for me, so it solves my debug build problem. However, you still
might want to change the location of ec_ilog's prototype in entcode.h
for those platforms that don't have an intrinsic like that.
