I know that there is a 'nls' function in R but I really do not have a clue about how to use it in this situation. Perhaps Box-Jenkins are confusing me with their last sentance with regard to the a_t's - is this really possible? If anyone could help me on this I would be most grateful. I know this is not exactly an R question, but to the best of my knowledge there is no transfer function estimation method in R at the moment and so this might be a nice additional fea...

...t place. If I'm reading you correctly, you are relying on exception propagation and handler (destructors for local objects) execution. You have chosen not to add extra exception logic to LLVM itself, but are relying on the correctness of exception propagation within the code. (The last two sentances are intended to be a restatement of what your message said. If I misunderstood, please correct me.) Does this mean that you're compiling your build of LLVM with exceptions enabled? By default, I believe LLVM is built without RTTI or exception support. For the particular cases you menti...

It was probably not completely correct to say that we did not extend the exception propagation in LLVM. In most of cases where malloc or other C allocation functions are called, we had to...

Hi Hal, > Does this mean that you're using C++ exception handling to manage the cleanup? No, not really. From the place where we're calling into llvm we are catching all exceptions that may occur during compilation, but normally we do not add any additional catch clauses into the llvm source itself. We mainly rely on correct stack unwinding by destructors in llvm when an exception is

...in a meetme conf from a SIP Phone -> OK, we have "Enter PIN Number" and then "You're the only person ..." and then MOH - now we call from outside through ISDN and want to enter the conf -> we hear few words from "Enter your PIN number" (sometimes all the sentance) and then *no more* audio in all Asterisk, for all devices. Sometimes break is created when ISDN party hangup, which means that all the conference went OK. It's now anymore possible to enter conferences or to call voicemails _from any device_: on CLI we see that everything is OK, but silen...

I suggest appending the following as a new paragraph to the Value section: As \code{sprintf} is simply a wrapper for the C function of the same name, it is the user's responsibility to ensure that the objects passed in \code{\dots} correspond to...

I'm not sure I understand the first sentance ("You have to use the Subprogram type only for the return type"). Here's what my code for creating function descriptors currently looks like (note that some parts are commented out for debugging purposes): DISubprogram CodeGenerator::genDISubprogram(const FunctionDefn * fn, Functio...

Hi, I''m starting to play with btrfs on my new computer. I''m running Gentoo and have compiled the 2.6.31 kernel, enabling btrfs. Now I have 2 partitions (on 2 different sata disks) that are free for me to play with, each about 375 gb in size. I wanted to create a "raid1" volume using these two partitions, so I did: # mkfs.btrfs -d raid1 /dev/sda5 /dev/sdb5 # mount

Hi all, I am attempting to build samba3 beta2 for AD support, and I've run into a brick wall. I am using Solaris 2.7 and 2.9, with gcc 2.95.2, with krb5-1.2.8 and (now) libiconv-1.9.1 Firstly, I am getting errors of the like: Error loading module '/usr/local/samba/lib/charset/CP850.so': ld.so.1: ./smbclient: fatal: /usr/local/samba/lib/charset/CP850.so: open failed: No such file or

I was discussing with Don about a private topic..and while skimming the code I noticed that during a 'ssh mouring at site ls' the /etc/environment is *ONLY* read if the remote machine is an AIX box. This is undocumented and I'm wondering if someone using AIX could explain WHY it exists in the session.c:do_child()? No other OS has this. I don't see why AIX should require it.

I hate to be a nag, but after several days of working on this I am still utterly stumped. Let me recap the situation as it currently stands: I'm trying to write code that generates DWARF debugging information for my compiler using DIFactory and friends. Unfortunately the information I am generating appears to be invalid, but I can't figure out the cause. Based on the advice in the

Hi all I'm guessing this is a little off topic but here goes... We use PXELINUX and kickstart to automate our RHEL deployments and updates. Recently we started using PXELINUX/memdisk and an MS-DOS image to update the workstation BIOS'es. After selecting <F12> (network boot) and picking the update BIOS option, the BIOS is flashed, BIOS configuration made standard and then the

I recently came across an enormous cluster of x86 clone machines running fedora core 1 (2.4.24) which have typically all intel or amd have VIA IDE chipsets. They frequently experience corrupted journals rendering the ext3 partition in read-only mode. More important than recovering the filesystem, I am interested in finding the root of the problem. The common hardware that all of these
