Hello Rails lovers! I have a few general discussions that I have yet to find terribly active. Perhaps all of the people busy on this front are...uh...busy on this front. So! Ajax-only apps. No degration. Yes! Forget about degradation for a moment. Not willing to? Ok, well...this question is for those who are willing... Imagine developing an app that is one page - all actions render partials

I have begun to use the reference function feature of sexy migrations, and I have noticed that the fixtures are actually not playing nice with this new feature. If I create a model, whose table has this line: t.reference :user the fixure will look like one: user: when it should be user_id, now, it may be possible (I don''t know, to define an object in the fixtures now, but when I run

I sent this earlier under with the subject "artificial sugar causes cancer" and I think some spam filters ate it. Here it is again: ====================================== All, If you look at http://rubyforge.org/tracker/index.php?func=detail&aid=6760&group_id=797&atid=3149 you''ll see that Chad (the submitter) found the source of the bug.

I am wondering what the list's opinion is on the Apple to Intel switch. This is going to put a slick desktop that runs on top of BSD directly into the mainstream. What does this hold for Linux in general, Linux on the desktop..and microsoft. -- Computer House Calls, Networks, Security, Web Design: http://www.emmanuelcomputerconsulting.com What businesses are in Brunswick, Maryland?

Hey guys, Looking through my book and the web and I am not having any success returning data from a search. I need to have awk search for a string and print the first field which is no problem but now its returning two options as the input data has changed. The change is reliable, I only want the first field if it ends in a regex that I have, and I only want what that regex matches to be printed.

I have installed asterisk on numerous servers. Every install was done on Fedora and (White box Linux). I now have zap channels in one of the boxes (T-1). No matter what type of channel I call on (sip or zap) I get some really strange artifacts in the sound, almost like a skip in the playback. It seems to always be in about the same place in the recording. Usually in the beginning of playback. For

All, If you look at http://rubyforge.org/tracker/index.php?func=detail&aid=6760&group_id=797&atid=3149 you''ll see that Chad (the submitter) found the source of the bug. Unfortunately, the source of *this* bug is the *solution* to a *previous bug* in which Rails was replacing RSpec''s method missing with its own. When we settled on underscores, my one reservation was

I have been looking around for Outlook Integration for Asterisk. Saw the Asterisk TAPI wiki page and also ran across this: http://www.fonality.com/pop.cgi?page=pop_pbxtray.tt (PBXtray) It looks like Fonality has managed to make an app that does screen pops and allows click to dial. Has anyone else been able to get this all to work successfully? Looks pretty slick.

Just started using mock to rebuild some srpms. I have two I want to rebuild, problem is the first creates a dep that is required by the second. Is there an automated way to populate an additional repo/cache that mock would look at when building the second so I could queue both? Although I haven't tried, I presume I could drop the output from the first build into a dir, createrepo it and add

Hi, I have an ActiveRecord model Group and a YAML table stored in config/users.yaml just like: - {login: titi, password: 123456, group_id: 2} - {login: toto, password: 987654, group_id: 7} And I would like to link them by a sexy way. Can you help me? I would be happy if I can do this (as example): User.first.group.id # => 2 Many thanks for any help! -- Posted via

I see that a number of questions are being answered on the new web forum that is now part of the centos site. And the mailing lists So now there are two places to search, both the forum and the mailing list archives. This is just doubles the work required to follow along or find a solution. I know NNTP isn't sexy, it doesn't allow graphics in posts, it doesn't have person

Hi all, let me ask a question, please. Is it possible in dovecot to set up per user special-use folder names? Imagine situation with two users where first prefere another language that second. mailbox Sent { special_use = \Sent } for english speaking users and mailbox "Odeslan? po?ta" { special_use = \Sent } for czech speaking users. Thanks for your answers. Radek

Today, I was looking for an elegant (and efficient) way to get a named (atomic) vector by selecting one column of a data frame. Of course, the vector names must be the rownames of the data frame. Ok, here is the quiz, I know one quite "cute"/"slick" answer, but was wondering if there are obvious better ones, and also if this should not become more idiomatic (hence

This deals with the Rails book, but ActionWebService in general. I''m having trouble getting the Rails book''s example in the Web Service chapter working. Everything else works (all the ''depot'' site features up to that point have been built and work). I don''t think it''s an issue with the book code being wrong, because the ActionWebService API

I sometimes buy myself a default value for a hash using something like this: h = Hash.new{|h,k| h[k] = ""}. I can now pass ''h'' any key and if a value has not yet been associated with that key I receive an empty string. I would love to do something similar in my partials so that I wouldn''t have to worry about passing in every variable that is referenced.

I am working with a somewhat complicated structure in which I need to deal with a function that takes ``basic'' arguments and also depends on a number of parameters which change depending on circumstances. I thought that a sexy way of dealing with this would be to assign the parameters as objects in the environment of the function in question. The following toy example gives a bit of the

Friends- I am almost finished with a custom live cd called Rubuntu ;-) This is an ubuntu live cd variant that comes preloaded with ruby and rails developers in mind. I already have it working with all the basics but I was wondering what extras people would like to see on this distro. What editors with what configurations? What other tools do people really like for rails development on a

Hi, this is probably a very trivial question but I can't figure out the right terms to find the solution in the list archive. I have a matrix or a data.frame or the like: > m <- matrix(ncol=3,seq(1,9)) > m [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 and now I wonder if one can provide somehow two vectors, one containing row numbers, the other

I just finished posting an article on creating a lightweight but very functional web grid that does a slick job of live updating whatever content you put in. Much like Rails itself, I pulled the code from an active project effort, in the hopes that others would find it useful. http://unspace.ca/discover/datagrid Or, for the impatient, give the demo a shot: http://unspace.ca/datagrid Feedback

Suppose I have a square matrix P P <- matrix(c(.3,.7, .7, .3), ncol=2) I know that > P * P Returns the element by element product, whereas > P%*%P Returns the matrix product. Now, P^2 also returns the element by element product. But, is there a slick way to write P %*% P %*% P Obviously, P^3 does not return the result I expect. Thanks, Harold [[alternative HTML version
