so I have some local users that I'd like to show up in my samba domain a

I've tried to create an idmap entry (probably wrong) and a structural
SID with a sam account pointing to the numeric UID and a proper name for
the unix account, but it still shows up as UNIX-USER/accountname. what

[LLVMdev] Is it possible to run llvm on mips machine?
Hi,
There are numerous emails flying around the list at the moment regarding the state of the JIT. In its current state it is infeasible to add support for another architecture (very difficult to say the least) - there are plans currently being formulated to deal with this and convert the JIT to the new MC architecture, which would allow much easier porting between platforms.
Have a look for the subject "[LLVMdev] MC-JIT Desig...

Sample size estimation for non-inferiority log-rank and Wilcoxon rank-sum tests
...f non-inferiority tests. The first would be a log-rank test and the second would be a Wilcoxon rank-sum test. I want to be able to determine the sample size that would be necessary to test for a 3 day difference in median recovery time between 2 groups of cancer patients.
Both of these tests are infeasible using SAS Proc Power and I haven't been able to find information about how to do them using either SAS or R.
Does anyone know how to perform either of these calculations? If so, I'd greatly appreciate it if you could share a couple of examples.
Thanks,

more structure than 'str'?
...9; -- to see
them.
I've found 'str' extremely valuable for understanding and
explaining to others the internal structure of an R object. In many
cases, it has helped me find fairly simple ways to do things with R
objects that might have been much more difficult and perhaps infeasible
without 'str' -- and without access to the right expert, who may not be
available in the time I have to solve a particular problem.
Thanks again to Martin Maechler, who wrote 'str', and to everyone
else who has replied to questions from me over the years.

[LLVMdev] Could LLVM or Clang go backward to modify c source code?
OK. Thank you.
What I want to do is: Fix source code in-place, then feed it to compiler
normally.
I assume I can fix source code in-place using clang::SourceManager, but I
cannot find the appropriate API.
Now I know that way is infeasible.
Thanks again.

Using C++14 code in LLVM
...ough: the
primary platform I care about is planning to be off of libstdc++4.9 (the
tall poll of the tent for us) by the end of 2018. So it seems like right
after the branch in January 2019 would be fine for us to bump things up.
Anything earlier than this will be somewhere between extremely hard to
infeasible for us.
At that point, we could probably go for C++17 as easily as C++14.
But maybe my group is unique in that timing so we should really ask others
for input as well.

Basic Coverage

My goal is that given a binary and the corresponding input. I want to know

I want to know whether there are some tools that can support this

do not know too much about this. Any

I'm having trouble interpreting this error message. It seems to me that
the problem is the initial point is infeasible, but I may be wrong here.
If I am right, I'm not sure why it is infeasible given that I have only
added a few simple conditions. Any thoughts?
Thanks a bunch,

Help: Sort components of a vector with indices tracked in R
.... Say, we have
c <- c(1,4,3,2)
csort <- sort(c,descreasing=FALSE)
With a few components of c, we can manually find out:
csort[1] = 1 = c[1], ie, the original index of csort[1] is 1,
csort[2] =2 =c[4], ie, the original index of csort[2] is 4.
When length(c) is very large, manual checking is infeasible.
We can set up a for loop to compare and extract the index. However, is there an easier way to do this, so that the output is the sorted vector and their corresponding original indices.
Thanks

Control number of assets in resulting portfolio with optimizations using package fPortfolio
...and the problematic part: the minimum weights level for each
asset is +0,01 OR zero (in order to control outcome portfolio size)
à Initially, considering that the minimum weight constraint is +0,01 for
each of the 1.500 assets and the sum of weights constraint (leverage) equals
1 would raise an infeasible problem for the optimizer. Given my additional
restriction that the minimum weight for any asset to get into the portfolio
should be at least 0,01 would solve the target conflict in between minimum
asset weights and the leverage of 1. The iteration path of the optimizer
should consider something li...

[LLVMdev] C as used/implemented in practice: analysis of responses
...different) executions
for the same source and inputs. Running with -fsanitize=undefined
will detect problems just on the executions that the current compiler
implementation happens to generate. Of course, checking against all
allowed executions of a very loose spec quickly becomes
combinatorially infeasible, so this isn't unreasonable, but at lease
we'd like to have that gold standard precisely defined, and to be able
to pseudorandomly check against it.

How sample without replacement on more than one variables?

three vectors such that the combination of the three elements in each
draw is not the same as any previous draws. I could use expand.grid to
generate a vector out of the three vectors. But when the number of
vectors are large and the number of elements in some vectors are
large, it will be infeasible to do so.
If you know there is a method on sampling on more than one variables,
would you please let me know? Thank you!
