Hello, What is the best way of solving this problem? answer <- ifelse(tf=TRUE, i * 5, previous answer) where as an initial condition tf[1] <- TRUE For example if, tf <- c(T,F,F,F,T,T,F) over i = 1 to 7 then the output of the function will be answer = 5 5 5 5 25 30 30 Thank you. Phil,

...if any 4.2 users out there have a favourite "dumb" PCI controller to add a couple of SATA ports to a motherboard that doesn't include SATA support. I'm not looking for anything fancy, just 2 SATA ports that a recent vintage kernel will recognize without a lot of configuration gymnastics. The intended use is for relatively light weight internet browser workstations for younger students. Suggestions would be very much appreciated. Cheers,

This may not be possible... I have an aggregation of clwholename defined in my model. the aggregation builds clwholename from :first_name, middle_initial, last_name and it generally works fine. I am trying to add a validation so while there may be many ''John'' first_names, and ''Doe'' last_names, I only want one ''John Doe'' so I tried...

...samba provide a hook or feature, similar to the preexec/postexec script, except for a file write? I am willing to deal with performance implications, of course. An alternative would be an unlink-and-create-before-write approach when updating a file, though that would require samba to do some gymnastics. I'm not aware of any such feature. If nothing can be done, I suppose I will have to suggest that we move to per-user working copies, but if anyone has any other suggestions I'd love to hear them. Thanks in advance, Matt Mitchell

Hey all I am working with a technology standard (specific to the commercial print industry) by which each element within the workflow has bi- directional HTTP messaging. As each side needs a http server, I thought I could either: a) use a gem plugin to modify the behavior of mongrel b) subclass Mongrel::HttpHandler In short, its xml messaging between two points; each with a HTTP client

This would lead to unnecessary gymnastics assuming it were usable at all. Ports do that today. The problem with doing that is that it is easy for the encode/decode to be mismatched. I already did that and burned time discovering that. Lanai does this for example, as do others. I'd love to see people migrate away from that method t...

I suspect this has been asked 400 times, but Google yields 2-3 rather complex gymnastics in blogs (and possibly dated), and searching list archives on ruby-forum proves kinda useless. Using standard forms, it''s fairly easy to use @object.errors[:field_name] in the form to embed an error message right next to the field that has the invalid entry. The controller uses a simple c...

...rontend, and on the SelectionDAG). This seems to be the case here, to support targets with a more complex va_list struct featuring separate save areas for GPRs and FPRs, splitting a va_arg in to multiple operations (one per element of an aggregate) doesn't seem like it could work without heroic gymnastics in the backend. Converting the va_arg instruction to a new GETVAARG SelectionDAG node plus a series of LOADs seems like it may provide a straight-forward path to supporting aggregates on targets that use a pointer for va_list. Of course this ends up exposing loads plus offset generation in the Sel...

Hi all, We had some internal discussions about flipping the default for O0 and we concluded that we wanted to postpone it. *** Why Is That? *** We don’t want to send the wrong message that GlobalISel’s design is set in stone and ready for broader adoption. In particular, 1. The APIs are still evolving and can still possibly change significantly 2. The TableGen backend to reuse the existing SD

Dear R-devel: The following code seems to allow one function to permanently modify a calling function. I did not expect this would be allowed (short of more creative gymnastics) and wonder if it is really intended. (I can see other ways to accomplish the intended task of this code [e.g. via match.call instead of substitute below] that do not trigger the problem, but I don't think that is the point.) do.nothing <- function(blah) {force(blah)} do.stuff.with.call &...

This whole debate seems kind of odd to me. I don't know that cases where it isn't clear what type to use come up that often. If a value can truly never be negative you should use an unsigned value. If a value can be negative, you should use a signed value. Anecdotal evidence in my case is that the vast majority of values are unsigned by this rule. Is there a reason to use a signed value

The plugin would have to do some complicated gymnastics. It would have to keep track of which areas of the disk have been written and ignore NBD_CMD_WRITE_ZEROES for other areas, except if block-based storage is being used. And so yes we'd also need the imageio API to publish that information to the plugin. So it's possible but not trivial....

...onable set of canonicalization rules at the IR level that don't block optimization. Tricks like saving instructions, using bit masks, etc., should all be reserved for the codegen layer / DAGCombine. There, hasOneUse makes perfect sense because you're trying to peephole through architectural gymnastics, not trying to get systematic scalar optimizations to fire. Let's see if we have any evidence that reserving this transform for the DAGCombiner hurts things, how it hurts things, and what we can do about it first? -------------- next part -------------- An HTML attachment was scrubbed...

...the remainder loop), we really want to know if the alias checks we're introducing are going to survive a not. It occurs to me that, if SCEV's known-predicate logic were smart enough, it would seem practical to not introduce redundant checks in the first place (although it would imply some gymnastics when examining the control flow around the loop and then restructuring things when we generate the code for the loop). The scalar remainder loop, when reached from the vectorized loop, is already known to be vectorizable to a VF larger than EpilogVF. No need to introduce again any potential aliasi...

At the very least, I accept clarifying the wording to make it clear where braces should/shouldn't be used. I personally would still prefer a general "always add braces in new code" rule, given that I literally just ran into another case where a code change I made locally caused test failures because I'd forgotten to add the braces on a previously single-line if, although in this
