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
...be applied if there is only one user? Is it
valid if there are more that one users, if we cannot move something
into the 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...

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi Ahmed,
Did you run these experiments on a platform with a linker that makes
use of the AArch64CollectLOH-pass-produced information?
I'm guessing that the AArch64CollectLOH-pass information and a linker
that makes use of that information could affect the profitability of
the GlobalMerge pass?
Thanks,
Kristof

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:

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
profitability check to widest type and not allowing for other narrower t...

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.

[Proposal][RFC] Epilog loop vectorization
...o VF*UF, and/or the vectorized remainder loop may too require a scalar epilogue.
o It should be interesting to see how a single masked iteration that uses the original VF, say for UF=1, works. LV should hopefully already support most of what’s needed.
o The original Trip Count clearly affects the profitability of vectorizing the remainder loop. Would be good to leverage any information that can be derived about TC either statically or based on profiling, when determining EpilogVF. Potential speedups and overheads/slowdowns could possibly be demonstrated using extreme cases; what would the best and worst...

Volunteer RoR help for a non-profit? (point2good.org)
Not sure if this is the right place to ask the question, but it''s a good
place to start.
I am running Point2Good, a non-profit website built on RoR. P2G raises
money for charity by using Google Adwords for Search.

are many things I have done wrong or could have done better/differently.
