Database Concurrency Without a Web Server?
My Rails application requires a very busy worker process running in the
background at all times. I am launching this non-interactive process
using script/runner. This process is very busy and is communicating
with the MySQL server constantly. As I started putting some load on the
system to test, I started running into performance issues.
I have since discovered that Rails is only using 1

Using EventMachine to listen from non-network
I''ve actually found a way to make EventMachine listen to events from a
serial port, but only by using the pure Ruby version, using Guilliame
Pierronnet''s Ruby/SerialPort library. It turned out to be simpler
than I thought it would be:
require ''serialport''
$eventmachine_library = :pure_ruby
require ''eventmachine''

Remote Postgres is driving me crazy!
Hi guys,
I need your help. Here is my database.yml:

libevent
Francis,
I read in the list archives back that a future EventMachine release
will support epoll on Linux (i.e., it''s in the trunk).
Better still, is there a possibility that EM will rely on libevent so
that it will be architecture independent (i.e. epoll on Linux, kqueue
on FreeBSD/Mac OS X, /dev/poll on Solaris)? This is how memcached is
implemented, and it would be helpful to be able

Howto: Check_box with a variable (no model)
Hi,
I would like to put a checkbox on a form where the input field is a
variable rather than a field in a model.
The normal way (with a model) would be:
<%= check_box(''client'', ''accept'', {}, "1", "0") %>
But since accept is a variable @accept and model client will not be
there, how do I make a check box work?

Periodically Call Remote Condition
Hi guys,
I''ve been reading through the forums and came across a response for
adding :with condition to a periodically call remote.
I tried it out and couldn''t make it work. Would anyone have a sample of
how to use this conditional structure with periodically call remote?
If not, does anyone have any idea how to add a condition to a
periodically call remote?

[PATCH] Allow generic autocompleter (Ajax.Watcher)
Hey. Below is a patch to allow generic Ajax.Autocompleters. Basically
it''s for people who wanna be able to watch an input for changes, but
don''t want it to pop up an autocompleter box below. Useful for live
previews, that kind of thing.
Someone''s gonna have to fix the tabstops. I couldn''t be arse to work out
how to make vim do the softtabs properly. Spaces for

Problems with repeated calls to setTimeout?
Prototype.js and Thomas''s effects scripts use repeated setTimeout calls
for timed looping, for instance in time-based observers.
On Konqueror 3.4.1 (possibly other khtml-based browsers, too), these
observers reproducibly crash the browser. Just keeping open a browser
with such an observer is enough. After some time it invariably
segfaults. When I substitute setInterval for setTimeout

libevent
Hello,
I have been looking at the Ruby/EventMachine. First let me say it look very
good. Reactor model with no threads makes for fast reliable server, and I
have read about marvelous Twisted framework for Python and am glad to see
something similar for Ruby.
I am writing network app with Ruby threads now and it very slow, and I try
new Ruby 1.9 with native threads that make it much slower.

Scaffold a Plural table w/ No Pluralization in environment
Hi guys,
I have a situation here. I have my project set to no pluralization due
to legacy tables in environment.rb. Now, I have some new tables which
I''m starting to pluralize. When I do a generate a scaffold to this new
table:

Observing changes to a text field
I''ve noticed that using several TimedObservers (prototype.js) on a page
to watch for changes to text fields (haven''t tried forms) can have a
non-negligible effect on the CPU cycles used by the browser process.
Nothing dramatic, to be sure, but unnecessary.
Autocompleter.Base (controls.js) follows a smarter strategy to watch for
changes. Currently this functionality is tied

How do I overwrite/extend a scaffold module?
I have many pages to generate quickly. They are based off of the scaffold
generator, but I want to convert the rhtml files to Markaby, and change some
formatting. Without having to do a lot of repetitive hand editing. Is there
a simple way to overwrite/extend part of the scaffold generator? Do I need
to write my own from scratch?

Ajax fade effect
I have a list of categories, when I delete one of them, I want that item
to fade and then get removed. So I do the following:

@element_id = @category.name
Category.delete_all(["name = ?", @category.name])
end
2. delete.rjs:

Event loop responsiveness + client
Hello, on the application that I''m working on, we are using Thin.
The server implements long polling and commands that alter its internal state.
Connecting to the long poll is a very fast operation, while updating
the state of the server is a relatively slow operation.
The long poll connection is held open until there is a change to be

Lighttpd Conf Help - Multiple Domains Multiple Apps

I hope someone can help me out. I am trying to configure two
