similar to: Ticket 6000 (was: a year of rails magic)

After working professionally with Ruby on Rails for a year, I decided to write an article on my experiences with the framework. http://nathany.com/developer/rails-magic Since I detail a number of things that I found unintuitive or could be improved upon, I am posting a link here on the Rails Core in hopes to stimulate David Heinemeier Hansson and the core team towards an even better 3.0

Hi guys, I have a code in R and it was work well but when I decrease the epsilon value (indicated in the code) , then I am getting this error Error: evaluation nested too deeply: infinite recursion / options(expressions=)? any help please y = 6.8; w = 7.4; z = 5.7; muy = 7; muw = 7; muz = 6; sigmay = 0.8; sigmaz = 0.76; sigmaw = 0.3; betayx = 0.03; betayz = 0.3; betayw = 0.67 s =

Hi, I am fitting a weighted least square regression and trying to compute SSE,SST and SSReg but I am not getting SST = SSReg + SSE and I dont know what I am coding wrong. Can you help please? xnam <-colnames(X) # colnames Design Matrix fmla1 <- as.formula(paste("Y ~",paste(xnam, collapse=

[I originally sent this mail to Martin and Richard, but then realised it's of wider interest, so I'm resending it to the list with Martin's reply attached (with his consent)] I was talking to Richard about trying to use shortened dividing keys in the B-trees. Shorter keys are better because you can then fit more in each block, so you need fewer B-tree levels for the same data.

Dear list member, I struggle with the problem, why the probabilities of choosing one of three mutually exclusive alternatives don?t sum up to 1! Let?s assume we have three alternatives X, Y, and Z. Let?s further assume we know their respective utilities: uX, uY, uZ. I?m interested in calculating the probability of choosing X, Y, and Z. Since I assume that the alternatives are mutually

NAME rq v2.3.2 SYNOPSIS rq (queue | export RQ_Q=q) mode [mode_args]* [options]* URIS http://raa.ruby-lang.org/project/rq/ http://www.linuxjournal.com/article/7922 DESCRIPTION ruby queue (rq) is a zero-admin zero-configuration tool used to create instant linux clusters. rq requires only a central nfs filesystem in order to manage a simple sqlite database as a distributed

HISTORY --- 2.3.3: - fixed bug in updater related to io files (see tmp_stdin in jobqueue.rb) - [IMPORTANT] removed feature where stdin jobs could contain comments (''#''). input lines are now taken literally __except__ blank lines, which are still ignored. - added ability to dump stdin/stdout/stderr for any job rq q stdout 42

Hello, My question has to do with a form resubmit problem. Say for example a form is submitted and within that form, a picture is uploaded. If the user presses the Back buttom and gets back to the form submission sheet, and then clicks on resubmit, once again, the same data is populated into my tables wasting space (another picture upload for no reason in a separate row). Now, I know there are

Hi, due to some idiot not being able to configure his Exchange server correctly, this list has been swamped by loads of duplicate mails. There were still several hundreds of mails awaiting delivery to this list. I have removed all of those from the mail queue - so if you are missing a mail you have sent, please resubmit it, it probably was lost while I cleaned the queue as I had no way of

Hi, I run a small IMAP server for a dozen guys in the office, serving about 55GB of Maildir. I recently became aware of the Zlib plugin ( http://wiki2.dovecot.org/Plugins/Zlib ) and wondered 1. given that there is about zero CPU load on my IMAP server, is enabling the plugin a no-brainer or are there other things (except CPU load) to consider? 2. For enabling the plugin, I suppose you

I'm on a dell inspiron 6000 laptop with Ubuntu 7.10 and WINE .9.46 installed. I installed the Might and Magic Millennium Edition (Might and Magic 4-7), and am having problems playing the games. When I try to run the games, it asks for the CD, even though the cd is in the drive. When I go to the Wine Configuration and the drives tab, there is no D drive listed. So I hit 'Autodetect'

First, has anyone successfully installed the HPLIP driver from HP in CentOS4? Second, does that driver really provide the toolbox which includes handy stuff like ink level monitoring? I got the source RPM (hplip-0.9.4-1.1.src.rpm) from an FC4 testing mirror, which rebuilt fine on this machine: . . . + umask 022 + cd /home/rj/rpmbuild/BUILD + cd

Folks: Granted, this slipped past my review too, but do *not* submit patches that have not been tested. This bug was a no brainer; running the code only even once would have found it. The mainline of Vorbis is our face to the world. A simple mistake like this costs us credibility when we're already going to be fighting hard against some of the most powerful media organizations in the

Hi, I''ve done AJAX calls to Rails'' Controllers before yet never required to generate a response back to the view. In this respect, I have tried to keep it moronically simple and just add a node to see that it works, yet the response doesn''t come through / isn''t interpreted as it should. Long story short, code : // Have to use Mootools to integrate a

The ffmpeg2theora chapter[1] of the Theora Cookbook says that the only advantage of two-pass encoding is that you can hit a specific target size. But isn't it so that you can reserve bits for difficult parts of a video, which improves the perceived quality? It may be true that Theora does quite alright without two passes, but it seems like a no-brainer to me that two passes will always be

I asksed about this in November last year but got on response. Anyone have any ideas now? Does anyone here have any experience with using KVM/libvirt with RAID1 over IP/DRBD or other HA solution? I'm trying to figure out the hardware configuration I would need to be able to survive a failure or planned shutdown of any one unit in a virtualization cluster. KVM/libvirt makes moving

Hi, I'm using dovecot (version 2.2.13 on archlinux) in the simplest, no-brainer way possible. It sits between mbsync, which I use to fetch mail from servers, and Gnus, my MUA. Both mbsync and Gnus connect to dovecot with an invocation like this: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/ea/ I have three different mail accounts, all that changes is the final directory on the
