building random matrices from vectors of random parameters
Thanks for both the mapply and array approaches! However, although intended to generate the same result, they don't: # mapply approach n = 3 sa <- rnorm(n,0.8,0.1) so <- rnorm(n,0.5,0.1) m <- rnorm(n,1.2,0.1) mats = mapply(function(sa1, so1, m1) matrix(c(0,sa1*m1,so1,sa1),2,2,byrow=T), sa, so, m, SIMPLIFY = FALSE) print(mats)...

[LLVMdev] Upstream PTX backend that uses target independent code generator if possible
...will refactor and add unimplemented features while upstreaming it. That said, the source code from above link * is not guarantee to be compilable on other machines, * is not stable or bug-free, and * should not be considered as the final version for upstream. I decided to take the code generator approach (referred to as codegen approach) rather than C backend appraoch (referred to as cbe approach) for the following reasons (in fact, I had my first prototype in cbe approach, but later I abandoned it and rewrote in codegen approach). This would partly answer previous questions about comparison betwee...

Canonical way to handle zero registers?
Thanks, that sounds like it would work. Was this based on what any other target did? Or do any other targets take this approach? I just want to make sure that we don't already have a hook suitable for this. Overriding runOnFunction to run what could be described as just a "late SelectionDAG pass" sounds pretty intrusive. Do you remember other approaches that didn't work? -- Sean Silva On Dec 22, 2017 2:...

MTE -- discussion on Exception unwinding ABI
Hi everyone, I believe the ABI for exception unwinding on a stack tagged with MTE needs to be clarified -- hopefully we can start the discussion here? (Please feel free to add people to the thread that you think would be interested). I'll outline some possible approaches that I think seem good below, I know Evgenii and Peter have done a lot of investigation in this area for HWASAN, so I'm hoping you can see any problems I've missed, or indeed propose something better if there's another approach ;-) --- Extra restriction on landing pads --- No matte...

building random matrices from vectors of random parameters

difference between nls and nlme approaches
.../Tree hierarchical grouping (Tree and Families are considered random factors) and estimate the within and among families variance of the parameters. I understand from the Pinheiro and Bates book that there is a degree of freedom issue, but what are the real advantages and disadvantages of the two approaches? This issues is prompted by the fact that it is easy for me to have results using the first approach but there is no way that the second approach reaches some kind of convergence: it takes hours and the it stops without reaching satisfactory results. I have tried several simplifications of the m...

Viable Approach to Parallel R?
All, We are researching approaches to parallel R with the end goal of running R in a distributed manner on a Linux cluster. We expect of course to do some work decomposing our problems to be task-parallel or data-parallel, but wouldn't mind getting an initial boost working with "embarrassingly parallel" code sections...

Relationship between clang, opt and llc
...erstand that this has been asked, e.g., http://stackoverflow.com/questions/40350990/relationship-between-clang-opt-llc-and-llvm-linker. Sorry for posting a similar question again, but I still have something that hasn't been resolved yet. More specifically I am wondering about the following two approaches compiling optimized executable: 1. clang -O3 -c source.c -o source.o ... clang a.o b.o c.o ... -o executable 2. clang -O0 -c -emit-llvm -o source.bc opt -O3 source.bc -o source.bc llc -O3 -filetype=obj source.bc -o source.o ... clang a.o b.o c.o ... -o executable I took...

...project that aims to clustering tweets based on the text similarity and user profile. I noticed that "Clustering of Search Results" have mentioned disappointing performance.I am puzzled that is this project just concerned improve the performance of the old code or also trying to find new approaches? Besides clustering speed, how to evaluate clustering effect? Look forward to exchanging ideas with you.

Multi-page forms
I''m curious to see how others are dealing with the construction of multi-page forms. I can see a couple of ways to do this, each with their own advantages/disadvantates. Approach 1: * define one table with columns for each form entry. * define a method/view for each page, which only displays a subset of the fields. * submitting a page saves the data and moves on to the next page. This one strikes me as a brute force solution, but may avoid many problems. It may also resul...

test unit approach?
I''m just getting back to looking at backgroundrb after a long hiatus since June. I''m looking at creating some workers but I''m a bit stuck as to how I should write tests for them. What''s the recommended approach for unit testing of workers? The project will ultimately be used by a Rails app but I''m comfortable developing the worker code as a standalone in the beginning. Any suggestions or examples? cr

dual disk netboot approach
Hello, My challenge is to run Linux on a computer where I don't dare to touch the Microsoft Windows harddisk. Fifthteen years ago would be trick to attach a second harddisk to the computer and boot from floppy disk. In 2011 is the idea to attach a second disk and netboot it. One approach is to TFTP the kernel and append 'root=/dev/sdb1' This E-mail is however to seek advice for another approach. In this approach is the kernel also on the second harddisk. I see two possible roads, both with dragons on it. The PXELINUX only road: Will PXELINUX load a kernel from disk? The...
