Trouble Using AR Object based on a Piggyback Query?
Hi, I''m new to Rails and Ruby and can''t access methods/columns from an ActiveRecord object that is a "piggy-back" row as described by David here: http://www.loudthinking.com/arc/000235.html Via Console I can create the piggyback object but reading attributes gives "TypeError: cannot convert String into Integer" (this is in Console and the browser). Some commented Console output is below, and any help is very much appreciated! (I can also post my model object if needed.) # This is a regular old ActiveRecord...

piggybacking an action on an autocompleted field
Hi everybody, I''d like to add a custom action to be triggered after/when an autocompleted field has been/is beeing updated by the autocompletion process. I tried the obvious - a field observer -, but it doesn''t work (see code below). I know I could write the autocompletion code myself, but I wonder if there is a simpler/more elegant way? Any idea? TIA Alain The

Strange behavior when trying to piggyback off of "fitdistr"
Hello. I am not certain even how to search the archives for this particular question, so if there is an obvious answer, please smack me with a large halibut and send me to the URLs. I have been experimenting with fitting curves by using both maximum likelihood and maximum spacing estimation techniques. Originally, I have been writing distribution-specific functions in 'R' which work

[RFC] Placing profile name data, and coverage data, outside of object files
...eeds that information to do some post-processing step on the results of running the binary. That sounds a lot like the role of debug info. In fact, having a debugger open a core file is precisely equivalent to what llvm-profdata needs to do in this regard AFAICT. So it would be best if possible to piggyback on all the effort that has gone into plumbing that data to make debug info work. For example, I know that on Darwin there's a fair amount of system-level integration to make split dwarf "just work" while keeping debug info out of final binaries. If there is a not-too-hacky way to pig...

[LLVMdev] Timing the IRReader
...g took (perhaps expanding it later to break down materialization, etc). In addition to significantly minimizing un-accounted time, this can facilitate future attempts to optimize the IR reading code. Any objections/insights? If this is deemed useful, there's the question of implementation. 1. Piggybacking on time-passes (like DWARF dumping does) is probably not the "right thing to do", and hard to implement too since some tools like llvm-diff don't even link in the pass infrastructure (which defines the required globals). 2. Creating a separate flag is feasible, but IRReader is curr...

RFC: Synthetic function entry counts
...rocedural BFI computation is likely to be more expensive in terms of compile-time. - Many function passes invalidate the BFI. This will require selective invalidation of function BFIs. - Inliner correctly updates function counts of a callee after a callsite is inlined. We can piggyback on this mechanism by using synthetic counts. -------------- next part -------------- An HTML attachment was scrubbed...

New 'quiet' behavior - optional?
...e. However, since 3.74 this also means that PXELinux runs quietly, making it impossible to see if the image is properly loading, or if it is stalled, or slow. We appear to be left with no way to specify (that I can find) the quietness of the two independently. (In my view, it was undesirable to piggyback off of an already existing commonly used parameter - making it impossible to separate the two). This means we are left with two undesirable choices, to either run completely silent (making network or server or pxe firmware problems very difficult to detect), or run without quiet completely, which...

Where does LTO remove unused functions?
Hi! LLVM newbie here, I was mainly working on the frontend so far. We had a small hackathon project idea to piggyback on LTO to detect dead code (unused functions). The basic idea is to compile the code for every target and dump the removed functions. Intersect the function symbol names for each target and those functions should be safe to remove from the source code (unless there were some configuration that was...

RTP/RTCP payload?
...n this case, not adequate by the reasons in RFC-1889. but I don't think that's enough. rather than sending comments in the same RTP packet, we'd better send it in RTCP packet. to do that we should define an RTCP APP name field for needed situations, or an RTCP extension. (or, could we piggyback on RFC-2793 and rather define an XML format?...) of course, when the tarkin goes beta, we would need to define its own payload, AND the payload for multiplexed physical stream, which could be compared to RFC-2343. ps. personally, I was a little shocked to see that http://xiph.org/ogg/vorbis/faq....

FWIW, I also started working on a Fortran frontend (derived from Clang, but mostly just to piggyback on the Driver and CPP infrastructure). https://github.com/hfinkel/lfort If you're interested in contributing, that would be great. Nevertheless, I think that Anton is right. Creating a quality Fortran compiler is a community effort, and seems too big for a GSoC project. Perhaps we could identi...

Grub2 on Xen PV
Hi, Let me start a new thread for this. I contacted the Grub people, and they seem more interested in creating a native Xen port of Grub than piggybacking the Mini-OS environment usin kexec as I tried. But they need some documentation on the Xen "firmware" to assess the task at least. What could be given to them apart from hvc_xen.c and xen-blkfront.c in the Linux sources? blkif-drivers-explained.txt? For a start, Grub has a Coreboot...

Rails and MSDE
Has anyone worked with Rails on Microsoft''s MSDE database server? (Not SQL 2005 Express, but the older MSDE) I''m curious on the performance and stability of the SQL Driver for Rails. I have a client needing a new web app, but I have to pull and store the data from MSDE (I have no choice on changing this). -- Posted via http://www.ruby-forum.com/.
