[LLVMdev] select1st, select2nd
I've run into a use case where I'd like to use a mapped_iterator to iterator the 1st (or 2nd) items in a sequence of std::pairs. Does select1st/select2nd exist somewhere within LLVM or is there some equivalent? If not, I'll add it. -Dave

Asterisk + Cisco 7920 + chan_sccp or chan_skinny
Greetings, I have seen a few postings in the past regarding the interop of Asterisk and the Cisco 7920 WiFi phone. To date, I have not seen a definitive method to getting the phone working. Assuming someone has this actually working, can that person step up and answer these questions. 1) What Channel is it working with (chan_skinny or chan_sccp)? 2) If code was used that is not a part of a

Summary on random data with zero skew and some kurtosis
Thanks to all who response my problem. Here are my summary : 1. from Dirk Eddelbuettel <edd at debian.org> We could try a mixture of normals -- ie flip a coin (use a uniform with some cutoff c where 0 < c < 1 ) to choose between N(0, sigma_1) and N(0, sigma_2). 2. from Michaell Taylor <michaell.taylor at reis.com> We could use the gld library to specify the lambdas of

smooth non cumulative baseline hazard in Cox model
Hi everyone. There's been several threads on baseline hazard in Cox model but I think they were all on cumulative baseline hazard, for instance http://tolstoy.newcastle.edu.au/R/help/01a/0464.html http://tolstoy.newcastle.edu.au/R/help/01a/0436.html "basehaz" in package survival seems to do a cumulative hazard. extract from the basehaz function: sfit <- survfit(fit) H

RFC: Cleaning up the Itanium demangler
Hello all, The itanium demangler in libcxxabi (and also, llvm/lib/Demangle) is really slow. This is largely because the textual representation of the symbol that is being demangled is held in a std::string, and manipulations done during parsing are done on that string. The demangler is always concatenating strings and inserting into the middle of strings, which is terrible. The fact that the
