probablly a newbie question: Rails does not support a table with multiple keys ??? it seems that the ActiveRecord set_primary_key method can only set the column name... (hope i''m wrong there) example: table A - P.K id, string name table B - P.K id, string name table C - P.K a_id and b_id, both are...

I realize thi may be more complex issue than can be asnwered in this post. But, what I need to do is create a simple query on my existing tables via a search form. I have half my app done (I can write all the info I want to my database), but pulling the data out dynamically is giving me trouble. I have both the "ruby for rails" book and the Agile Development book. They both give

rsync does not sync the timestamp on symlink (Solaris 8). It is probablly due to the limitation of Unix implementation of symlink, but I would like to know why rsync/Unix does not do this, and what we can do about it. Is the conclusion that "rsync syncs everything except the timestamp on symlink"? Why do I need timestamp on symlink? Supposed something stopped...

Hi all, I have an installation where each user on subnet 192.168.1.0/24 is connected via a multiplexer. The problem is that if any client uses more than about 48Kb/s, the multiplexer crashes. I need to limit each client to under this rate, say 32Kb/s. I have seen examples on creating a class per host but is there a simple way of saying "any host from 192.168.1.0/24" so I dont have

...by doing later inlining we could get the same situation and we would not know that we should strip invariant.group metadata. Other idea is following: We can replace the pointer by another pointer after barrier like: if (a == b) use(b) => if (a == b) use(barrier(a)) This would be probablly correct, but I am not sure if it is a good solution, because It might actually make it worse from optimization point of view. I am also not sure what should be the semantics of the barrier(constant) - should we constantfold it to constant? I am not sure if constant pointer can carry any invariant...

[My apologies if this question is deemed inappropriate for this list.] Using OpenSSH, is it possible for a program/script to copy files with known filenames from a remote server (running sshd), without allowing (interactive) ssh access to that server? I.e. ``ssh server ls'' or ``ssh server'' should not be possible (for security reasons), but ``scp server:file .'' should.

Hi there, I was just wondering how I would go about creating a bash script for Steam apps. I just started college in Pre-Biochem. and Pre-Comp. Sci. so I'm not far enough in yet (and midterms are coming up, how embarrassing) but the point is, I don't know how to create a bash script for steam apps. I know they start up steam first, then log in, and then get into the game. I'm not

All-- su cannot be run without trusting the shell. The shell cannot be trusted without trusting any instructions the shell uses, from library calls to rc scripts. Hell, the instructions the shell uses can't even be trusted, since they're all living in userspace memory. By contrast, SSHD is generally a root owned, highly secure environment with no unpriveledged userspace

Hey all, I''m thinking about moving my 2.0.7 install over to 3.0.0 for eventual use in a production environment. Two questions: 1) Do people think 3.0.0 is ready for production - or is it just a testing/unstable playpen? 2) What do I have to change - just the xen-2.0.7.gz for do I have to recompile the dom0/domU kernels too?

Dear all, I'm looking for primary help at aggregating table() results and at writing a loop (if useful) My dataset ( http://goo.gl/gEPKW ) is composed of 23k rows, each one representing a point in the space of which we know the land cover over 10 years (column y01 to y10). I need to analyse it with a temporal sliding window of 5 years (y01 to y05, y02 to y06 and so forth) For each period
