Hi, I have several machines using xen-hypervisor-3.2-1-i386 from etch-backports and they recently got upgraded to 20 or 24G RAM. I have seen talk of a limit of a 16G RAM with 32bit PAE Xen and indeed this is what I am seeing. I am guessing there is still no way to get the 32bit hypervisor to see more than 16G RAM, and I must go to 64bit. Can I boot a 64bit hypervisor and still keep the same 32bit dom0? What're people's experiences running 32bit domUs on xen-hypervisor-3.2-1-amd64? Cheers, Andy --...

...Maybe it's people using Herald to subscribe to changes in particular parts of the codebase - so when someone starts a code review all the Herald subscribers end up cc'd on the initial mail? I wonder if the Herald subscribers should be bcc'd or handled in some other way? If that's what's happening, and it's the right way to do it, I'm not sure what the right limit is - as more people use Herald we could get larger and larger CC lists. What's the mailing list limit for? What're the tradeoffs of setting it higher, or removing it entirely? - David

Hey folks, If I've got some code that I can compile using clang, that depends on a certain endianness, can I generate bitcode that will have the code operate correctly, even if run on machines of the the opposite endianness? If not, what're we talking about in specific work that'd be needed? Thanks, - Lally

What exactly is different between the 32 and 64-bit version of CentOS 4.2? The kernel (drivers, file system, etc.) is probably compiled to support 64-bit and probably glibc. What're some important differences between the 32 and 64-bit version? I'm just trying to get a deeper understanding. T...

...by the way. If there are outstanding users cleaning the context under their seats might still pose a risk to them, and in that case deleting + newing a new LLVMContextImpl might actually not be very different.

Hi All, We've been working on enhancing LLVM's instrumentation based profiling by adding indirect call target profiling support. Our goal is to add instrumentation around indirect call sites, so that we may track the frequently taken target addresses and their call frequencies. The acquired data has uses in optimization of indirect function call heavy applications. Our initial findings

I've been seeing this in my log (test69) for a user who has Thunderbird as a client: Error: IMAP(andrew): Corrupted index file /home/a/andrew/Maildir/dovecot.index: header doesn't end with NUL Thoughts? -D -- <dr.pox> what're the units of the coefficient of agnosticity? I don't knows per hour?

I have a user who accidentially deleted a large number of emails prior to a certain date. He wants them back. I do have a tarfile backup of these messages. Is there a good way to restore them? Can I simply restore them to the appropriate Maildir directory and dovecot will just "figure it out"? Thanks, --Mark

I don't know where we are on that list or what features people still need. I’ve come around to the point of accepting the inevitability of moving to cmake, but I think there’s quite a bit of work to be done to get everything to work.

...directly the destructor of LLVMContextImpl on the pImpl object - Uses a placement new to reinitialize the object. - Recreates the fixed metadata kinds like the LLVMContext constructor does I'm attaching a patch that show this approach in this mail. I would like to know a general idea about what people think about this and see what people think would be the best approach would be.

Good morning, I am trying to recode the values of a column in a data frame and, instead of using a long series of if/else statements I would like to use a switch (as it is, for instance, in the C programming language). I have a column of this type: AT BB B1 B1 CC CC T6 B1 CC BB TT AT AT AT TT BB ... and I need to change this coding (if it's AT then it should be A1, if it's BB then
