the problem of buying and selling
I own a lot to the folks on r-help list, especially arun who answered every
of my question and was never wrong. I am disinclined to once again ask this
question, since it is more arithmatic than technical. But, having worked 2
days on it, I realized my brain is just not juicy enough....
Here is the problem.
Trust not for freedom to the Franks---
They have a king who buys and sells.

Binary optimization problem in R
Dear all,
I would like to solve a problem similar to a multiple knapsack problem and
am looking for a function in R that can help me.
Specifically, my situation is as follows: I have a list of n items which I
would like to allocate to m groups with fixed size. Each item has a certain
profit value and this profit depends on the type of group the item is in. My
problem is to allocate the items

txtStart creates a NULL file
Hello all:
I'm trying to use the following code to get commands, comments and results to a .txt file. It only appears to capture comments. When I comment those out with #, it creates a NULL file.
Someone seemed to have a similar problem with a mac GUI (https://stat.ethz.ch/pipermail/r-help/2010-September/253177.html) but the result seemed to be ambiguous. Is there a work-around?

Profit calculation
Dear guRus
Say I have a price vector, P which is P = c(20,50,40,50) for four
consecutive days.
My initial equity is say $100 and I re-invest the profits made in each
transaction so my equity curve increases.
If I go Long on day 1, short and short on day 2, long and long on day 3 and
finally short on day 4, how do I calculate the total profits using R?
Basically I stay invested at all times.

[RFC] Tablegen-erated GlobalISel Combine Rules
...e destination block can we still apply the pattern is we move
the result in the source block, etc.
The number of users may not be that relevant, but this gives use is a
notion of profitability (it is just how SDISel does this). This
actually ties back to the inter-basic-block case: is this pattern
profitable if it is between basic blocks with different frequencies.
In other words, I believe we should start to think in terms of how
profitable is a pattern. E.g., the source pattern as some cost and the
destination patterns as some other cost. Applying the pattern should
give us a profitability score, whi...

One more from me and I suppose a retort by you

help with unless
Hi,
I need a fresh set of eyes to look at this bit of controller code and tell
me why I might be getting an error message:
lookup = Profit.find(:all, :conditions => [ "user_id = ? AND
product_id = ?", uid, pid])
unless lookup.empty?
if (lookup.updated_on > 360.minutes.ago)

end
end
If lookup is empty, then I

Can xen pv drivers take profit from this ?
Hello,
some have maybe heard of the GPL dirvers for KVM.
See:
http://www.techworld.com.au/article/316219/red_hat_open_sources_windows_virtualisation_drivers
Is there any profit that Xen can get from this ?
Matthieu.

Simple one
Just a quickly beginner's question.
I wanna find the mean only from the values from a column related to specific
values from another one. Like, theres a 'region' column, i want the mean of
the value on 'profit' column only from "south" sells from 'region' column

Legal issues for non-profit radio stations.
Hi All,
Some time ago I emailed this list and mentioned (as well as a couple of
techinical queries) that I was trying to contact the PRS for information on
the copyright licencing requirements of a non-profit on-line radio station,
a few people expressed interest in this and asked I keep them updated. Well
I just sent my third email (transcript below) informing them that I will

[LLVMdev] Vectorization factor limitation in Loop Vectorizer
Hi Nadav/Devs
I am exploring Loop Vectorizer to vectorize i8 scalar operations into 8xi8 vector operation.
I was expecting the Loop Vectorizer to analyze the profitability for vectorization factor(VF) of 8,
However it is not doing so due to the widest type calculation done for the blocks inside the loop.
May be I am missing something, however, I am curious to know why Loop Vectorizer limits the

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
...?
It could, and does, from what I've seen (beware anecdata):
- reusing the adrp base prevents optimizing it (the various
Adrp*{ldr,str} LOHs).
- reusing the adrp+add MergedGlobal pointer, with indexed addressing,
doesn't prevent the AdrpAdd optimization.
All in all, whether GlobalMerge is profitable or not (by increasing
register pressure, or adding another indirection), whenever the LOH
optimizations fire, they reduce its usefulness.
AFAICT, the only case where LOHs help GlobalMerge is when the
MergedGlobal base is closer to the adrp sequence than the actual
global. Given that we only merge...

These checks are:

b) Alias result check (only if alias check is generated for first vector version)
Where the epilog vector trip count is large epilog vectorization with profitable width likely to give gain. Worst case probably after these additional checks executing the scalar loop.

Volunteer RoR help for a non-profit? (point2good.org)

money for charity by using Google Adwords for Search.
