Hi there, I have a piece of Matlab code I use to optimise a trding strategy. If there are any Matlab/R specialists out there, I would appreciate your help in doing the exact same optimisation in R. I suspect I would use nlm() in R but am not sure where to define my constraints. I have attached my Matlab code below for reference. Many thanks. Constraints function [c,ceq]=TriskellConstraints(X)

Hi, I am hoping someone can help me with a sampling question. I am using the following function to sample 10 unique observations: x <- sample(1:100, 10, replace=F) Given the first 10 observations, I need to sample another 5 unique observations from the remainder. I essentially want to do a Monte Carlo type analysis on the results. I would appreciate any feedback. Thanks -- View this

I have a simple program that read all HTML files from a directory and returns parts of the content and the file names which are HREFs to those file. I build the HREF string dynamicaly as PATH_TO_DOC_ROOT + "file_name". My PATH_TO_DOC_ROOT = http://127.0.0.1:3000/docman/public/docs. So, the final link that I am interested in might look like this:

Hi gurus, I need a way to do SNAT based on source mac before routing. This is because hosts attached to my gateway can have duplicate IP addresses, and I have to distinguish over them. I tried to use the nat tool that comes with iproute2, but this force to make a mapping only address to address, and I wanted to do it by mark (I also use iptables to do that). For example, I tried to

Hello, unfortunately I got some trouble using ext3 - the system hangs when working in a certain directory. Not completely, I can switch between consoles and reboot with SysRQ, but cannot do anything which requires disk IO: not start any applications, not umount, nothing. I could send the strace output, but I don't think this would help anyone. Sorry, but I don't have a clue where to start

Hi all, trust all is well! I was wondering if LLVM would have a Bazel integrated build in the future? I can imagine the benefits this could bring, especially with regards to remote builds and caching. I'm thinking of dumping the LLVM source-tree into my code-base and experiment with building LLVM via Bazel. Will pull requests be accepted for this? I won't mind contributing my changes

Hello everybody, I have just released tinc 1.0pre4. Changes: - New authentication protocol (better security, and faster too). - TCPonly and IndirectData are back (but not fully tested). - Documentation revised, it's really up to date with the released package now. - tincd -K now stores public/private keys in PEM format, but keys of 1.0pre3 can still be used. - Faster and more secure

Hello, I packaged the old ext3 patch for Debian, and now I would like to create a patch-package of the current version for kernel 2.4.9. I consider to include Theodore's ext2 and ext3 readdir speedup patches and modify the 0.9.9 patch as needed to apply it on kernel 2.4.9. Does anyone (except of me) use all this parts together and report them to be stable enough? Gruss/Regards, Eduard. --

Hello, recently Theodory Tso posted a patch for the ext2fs driver, which improves speed of find and similar programs. Background: the application access all entries in the directory in the order they are stored on the disk. The current ext2 (and apparently Ext3) run a lookup function for each readdir call, starting with the first node! Theodore stores a refference to the node which was accessed
