I don't see why they shouldn't, since the program behaves exactly the same (as far as anyone external can tell) as if it had been left there. Ciao, Duncan.

Exception Handling Deep Dive at Dev Meeting
...l. The interest from my part is the Windows Exception Unwinding which from what I read is like Itaniums. It also looks like this is the one implemented in LLVM and most everyone cares about. I understand in the face of optimizations the correctness comes into question but I'm looking for more intricate details on real scenarios that the people who have worked with this have encountered.

Select varying LS digits in long numbers?
Hi Folks, I'm trying to find a neat solution to an apparently simple problem, but one which turns out to be a bit more intricate and tricky than one might expect. Suppose I have numbers given to a large number of digits. For example 1234567021 where (though I don't know this beforehand) only the last 3 digits will be varying (and all 3 will vary). What I want is, give a vector x of such numbers, to extract the m...

Re: Problem using virt-sysprep with RBD images
Hello Richard, Haha, ok, here's a good one: I commented that if statement out at line 300, applied your patch (I see you updated the github of this code, perhaps that's the best place to grab the code from), and when I run virt-sysprep, I get the following parameter for my disk drive: >> qemu-system-x86_64: -drive

question on function arguments
...ble? The second call is more related to indices: i would like my argument b $x to be either a vector (default), or a scalar. In the latter, the loop b$x[ii] breaks when i would like it to recycle the single value. I can check the length of b$x with a "if" statement, but it becomes intricate when several arguments have this option of being vector or scalar. Is there a way to use b$x that would work in both cases? Many thanks, baptiste _____________________________ Baptiste Augui?

Adding info from summary(lm(...)) to plot
...#39;ve been trying to work out how to so this simply, but without much success. I can see a complicated way, which involves binding the row and column names, and the values, of the above output, using paste() along with "\n" at suitable places, but I'd like to have something much less intricate than that! I'd also like to be able to integrate the solution nicely with the main title (or the X label) so that there's no overlap. Any suggestions? with thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding at manch...

IAX2 over OpenVPN connection.... working but
...host= parameter within Asterisk accordingly on each end to match the local IP's and discovered it did not work. The trunk remained in an UNKNOWN status on each end, even though we could ping each box locally, SSH, and even SIP worked. Here's where I am baffled and I am hoping someone with intricate knowledge of this implementation may be able to explain it to me. What we had to do to get this working was to set the host= parameter to the respective endpoint IP's of the VPN tunnel, 172.10.1.1 in my case, and 172.10.1.2 in his case. Calls flow normally now and we cannot understand how or...

CentOS 6 P2V alternatives?
...rtualizing systems like this is kinda' new to me, having it done on Windows only, and I'm not really sure how to proceed when it's a CentOS system in question. The physical CentOS-server runs a few license managers and nfs-shares that server molecular modeling software, that are rather intricately set up (I inherited this server some fifteen years ago). Are there any easier ways to do a P2V at all? -- BW, Sorin ----------------------------------------------------------- # Sorin Srbu, Sysadmin # Uppsala University # Dept of Medicinal Chemistry # Div of Org Pharm Chem # Box 574 # SE-7...

Unsigned int displaying as negative
Tim, yes, I am on a very unique architecture, just about every instruction has a signed and unsigned operation (ie, adds, addu, subs, subu, etc...) and we handle signed and unsigned somewhat differently. I'm not sure how we'll handle this yet, very worst case scenario is to propagate the info from clang but that's not ideal, obviously. Thanks for all the replies! On Wed, Feb 15,

Dynamically setting up/tearing down extensions
Hello, * newbie here, I'm designing a setup that is to eventually be used in a production virtual PBX/VoIP service. Customers need to be able to change their setups over the web - I want them to be able to do simple things like setting up call forwarding, as well as more intricate stuff that will require me to re-generate their dialplans. Administration of the service is to be web-based. I'm looking at DynExtenDB (and have played with it). I love that it reads the dialplans out of a MySQL database - that is a critical issue for me. But it has some issues. I hav...

[LLVMdev] Structure returns to-do or not-to-do?
...rgument which is the a pointer to the returned structure, and the allocation is made by the caller. > Even declared, but undefined functions are converted like this, presumably this doesn't cause a problem during linking? Right now, conformance with the platform ABI calling convention is an intricate dance between the frontend (i.e. that which emits the IR) and the backend. So if the ABI says that a particular structure return is implemented by passing a buffer pointer as an implicit first argument to the function, then the front-end is responsible for generating IR that follows that patter...

Package inclusion in R core implementation
I concur with Avraham that capabilities need to be ensured e.g., in recommended packages. I should have mentioned that. My concern is that the core should be focused on the programming language aspects. The computational math and some of the more intricate data management could better be handled by folk outside the core.
