Part of my application counts the number of times a link was clicked. The Link.click function should increment the @link.clicks attribute. I assumed def click @link = Link.find(params[:id]) if @link.increment(''clicks'') redirect_to @link.url else flash[:error] = ''Could not update clicks'' redirect_to :action =>

Hi all, I have a problem in that when I plot points that have a high degree of precision, some significant rounding seems to occur, resulting in uneccessary overlap of my points. Is there a way to specify the resolution or precision in plotting functions? Is there an underlying grid I have to modify somehow? Many Thanks, Jon -- Mares eat oats and does eat oats and little lambs eat ivy. A

Hi Folks, BackgrounDRb is a Ruby job server and scheduler. Its main intent is to be used with Ruby on Rails applications for offloading long-running tasks. Since a Rails application blocks while serving a request it is best to move long-running tasks off into a background process that is divorced from http request/response cycle. This new release of BackgrounDRb is also modular and can be used

I am building an invoicing system but cannot use the auto_increment field to determine the invoice number (because they are running 3 different companies off the one system. I need to find the last invoice number from any given company and then add 1 to it to get the next invoice number. BUT, there is a unique case on the very first invoice produced because there is no earlier invoice

Hi, I have the following code: Message, belongs_to :topic, :counter_cache => true topic = Topic.find_from_permalink(params[:id]) topic.messages.create(params[:message]) When the message gets created, then AR issues a supplemental SELECT to retrieve the message''s topic and then updates its messages_count. Why is that happening? If I do it manually: if

Folks, I have the following repetitive code which works correctly: A = read.table(file="junior.csv", sep=",", col.names=c("date", "l")); A$date = chron(as.character(A$date), format="m/d/y"); r.junior = levels2weeklyret(lastfriday, A$date, A$l); plot(A$date, A$l, type="l", col="red", main="Junior levels")

It looks like flex 2.6.1 changed [1] the return code for EOF in yyinput. Therefore, use the right value depending on the version of flex which generates the lexer.

I am new to llvm so I might be missing a critical step. My system is Fedora 12 but this also happens in Mac OS X 10.6.2. Here are the steps I used to compile llvm: export TARGETS=x86,x86_64,cpp export INSTALLDIR=/home/rovitotv/llvm ../llvm-2.6/configure --prefix=$INSTALLDIR --enable-bindings=none --enable-targets=$TARGETS --enable-optimized --with-llvmgccdir=$INSTALLDIR

First, you have to call llvm-g++ to use the llvm-gcc front end, but it doesn't matter here. I'd like to suggest that you use pastebin to put your code and the send us the link, so that we can download it. The problem is that TheExecutionEngine is set to NULL (maybe because of a previous error), but it will be really better if you use pastebin. On Wed, Feb 17, 2010 at 6:01 AM, Todd Rovito

Hi all -- I recently temporarily deployed an upgraded Clearcase server (7.1.2.3) on 64 bit RHEL 5.6. With it I was using Redhat's release of Samba for that version of the OS -- 3.0.33. The system has 32 GB of memory and within 12 hours, it would be down into swap. Maximum active licenses used is 36 but a more typical load is 18-25 users having a Clearcase license at once.

Hi Volker, I have same behaviour here without enumerating users or groups.

Hello all, I have been doing some searching for information about disabling services within a CentOS 5.5 install. I have found a few different opinions, and wanted to ask for some feedback. First off, the system is running a LAMP stack to serve a web application. It will only be doing email to send occasional messages out (sent via the application only). It will not be receiving email for any
