Assorted Experience

Well, the right click (alt fire) on the suppressed pistol activates some magic device that can temporarily knock out a light - for about 10s or so. Why did I have to search on the internet and track down vague clues until I hit this page and found out for sure? Shouldn't there  be a manual somewhere? UPDATE: I gotta read the notes on the equipment screen more carefully... UPDATE2: The manual is useful. Save trees/animal skins, don't print it out.

A good guide is available here File:  /Library/StartupItems/RRiki/StartupParameters.plist : {  Description = "RRiki server";  Provides    = ("RRiki");  Uses        = ("Ruby");  OrderPreference = "Last";  Messages =  {   start = "Starting RRiki server";   stop = "Stopping RRiki server";   restart = "Restarting RRiki server";  }; } File: /Library/StartupItems/RRiki/RRiki #!/bin/sh ## # RRiki service startup script ## . /etc/rc.common StartService () {     ConsoleMessage "Starting RRiki"     cd /Users/kghose/Source/Rriki2/     /usr/local/bin/thin start -eproduction -d } StopService () {     ConsoleMessage "Stopping RRiki"     cd /Users/kghose/Source/Rriki2/     /usr/local/bin/thin stop  } RestartService () {     ConsoleMessage "Restarti...

Now using thin rather than mongrel. Seems to be fast and responsive and most importantly installs without errors.

in partial (view) <%= select('history', 'sel', history_list, {:selected => selected}, {:class => 'historyselect'}) %> <%= link_to_remote 'x',       :url => {:controller => 'rriki',                :action => 'clear_history'},       :html => {:title => 'Clear history'},       :method => :get %> <%= observe_field 'history_sel',     :url => {:controller => 'rriki',              :action => 'select_item_in_history'},     :with => 'history_sel' %> changing the select will call the action select_item_in_history with params['history_sel'] set to the selected value.

Partials can take parameters (called locals), but can crash your app if a caller does not pass a local and you try and access it in the partial. You can use the following construct to initialize a variable if it does not exist var = nil unless defined?var where var is your variable

When parts of a webpage are updated using AJAX calls (e.g remote functions) these updated parts do not show up when you ask Firefox for the webpage html (using CTRL+U). A hack to see the generated html from a suspect rails call is to simply print out the html on the webpage instead of executing it by doing: <%=h ...rails command... %> Instead of <%= ...rails command... %>

I had a select tag that I wanted to mess with a little to apply some styles etc. to. The select tag has an html_options hash and I was trying to use that. My initial attempt was select('history', 'sel', history_list, html_options => {:class => 'historyselect'}) WRONG This is not python, and even though the rails docs setout the syntax as: select(object, method, choices, options = {}, html_options = {}) ruby can not accept keyword arguments. Only positional, so you have to do: select('history', 'sel', history_list, {}, {:class => 'historyselect'}) The empty braces signify the empty 'options' argument, and the next set of braces signify the html_options hash
