Has anyone extended Rails''s acts_as_tree to use the Modified Preorder Traversal algorithm? This is a really clever trick for optimizing access to trees stored in databases, as described lucidly in this article: http://www.sitepoint.com/article/hierarchical-data-database/2 It adds two integer fields, a "left counter" and "right counter", to each row. By

I am using JRI (Java R Interface) library in order to call R from within my Java application. But since the "rmu1" and "rmu2" ,see the following code, are objects of type S4 once i run the application the value of Null will be returned for both of them. On this regard, i would appreciate it if anyone can tell me how i am going to display and/ or convert these objects to Java

That looks like it does a preorder depth first traversal (I think). I'm looking for postorder. Is there a trivial transform between the two? (I don't know one.) Am I wrong about the preorder/postorder? If not, anything lurking for postorder traversal?

Too obvious!

Check out "llvm/ADT/DepthFirstIterator.h", it lets you iterate

Hi, I have preordered natural selection quite a while ago and it seems like it is getting to a playable state, so I wanted to know if anyone could help me (and many others :)), to get natural selection 2 to work with wine. I would gladly give you a console log, but i don't even know how i start steam-games from console :/. (when i try "wine Natural\ Selection\ 2.exe", it says that i

My apologies in advance if this is the wrong list to ask this in, but how well does pf work in 4.8-STABLE? And if so, what kernel options do I need to compile in? Can pf kernel options coexist w/ IPFW options, if I keep the IPFW modulus from loading? Can I still bridge in regular fashion w/ pf? I've already read up on http://pf4freebsd.love2party.net/install.html, but this seemd a bit

Thanks Andy, helpful as always! 1 is a possibility, but not ideal for us. Could you elaborate a little on 3? I don't really know what a jump stub is, but am guessing it's a kind of "alternative symbol" which would just act as a middle man to invoke the "real" symbol in the static library. If that's the case, I can think of a way to implement it for specific

For nefarious reasons I won't go into (this is for a quick hack that will be thrown away in a week or two), I'd like my Asm printer to get MBBs in a depth first order. Is there an existing pass or function that will let me do this easily? Thanks, Dan

hello, On page 49 of the beta version of Ruby on Rails: Up and Running, the book suggests to download a zip file containing everything that has been done up to that point, and a create_tables_with_data.sql file. The book doesn''t have the link, and I couldn''t find it in the book site. Does anyone know where to get the files? This is a very good book. Thanks. -- Posted via

Some time ago I posted here regarding a relocation overflow on Windows (among other things), but the issue disappeared and so the thread got left. I've started this new thread because a) I didn't want to necro the old one and b) it felt like its own. I've now encountered the issue again and am noting down all the information I can get about it whilst it's happening. The issues is

http://www.x100p.com/products_2.htm Anyone ever use this box? How's it compare with the Iaxy? I'd like to buy one or the other.. The Iaxy is appealing because to me, it seems less "no name", but this one says that it supports using hostnames, whereas apparently the iaxy only supports IP addresses?? That's appealing to the dynamic DNS guy in me! :-) Any

Hi everyone, My apologies if this isn?t the right place to submit this?I?m new to the R-devel community and still figuring out what is where. If people want to skip my writeup and just look at the code, I?ve made a repository for it here: https://github.com/ahl27/new_dendrapply/tree/master. I?m not quite sure how to integrate it into a fork of R-devel; the package structure is different from

First of all, thanks very much to Lang for fixing the BSS section bug; works like a charm! I’ve been unable to reproduce the 32 bit relocation on 64 bit code (I’ll let you know if I do). However, I’m still having issues with resolving the 64 bit symbol relocations. In case it’s relevant, the specific symbol my program is tripping up on is IID_IOleObject, where TargetAddress is dereferenced

Hi folks! How do I extract lags from a formula? An example: mod.eq<-formula(x~lag(x,-1)+lag(x,-2)) > mod.eq x ~ lag(x, -1) + lag(x, -2) > mod.eq[1] "~"() > mod.eq[2] x() > mod.eq[3] lag(x, -1) + lag(x, -2)() I'm trying to extract the lags into a vector that would be simply [1,2]. How do I do this? I'm using the dyn package to do dynamic
