Merb plugins (gems): merbful_auth: works, but terrible, terrible code. Do not use.
paperclip: Doesn’t work.
If ssh agent forwarding doesn’t work in capistrano, update your net-ssh gem.

Given(“I am an activated, logged in user”) do
Given(“I am a user”)
Given(“I am activated”)
Given(“I am logged in”)
end
c[:session_store] = ‘memory’ if Merb.environment == “test”
Foo.class_eval do
def bar
puts “reopened class and replaced instance method”
end
end
Mocha can mock an instance method on all instances of a class. RSpec can’t.
You can take the boredom out of peepcode by running it at 1.5x speed using Quicktime.

RFC4366 (implemented in nginx, firefox 2, etc) makes it possible to run multiple SSL sites off a single ip/port
Forget sshfs; transmit is the best way to hack files on a live site.
rspec: integrate_views OR DIE!!

Yeah, Radiohead’s recent release was great, but they forced you to sign up to a spam list just to buy it. If you email them asking to take you off, they don’t. Magnatunes.com has been doing the drm-free thing for years, and doesn’t spam you (or even require a valid email address).

Yugma: Free, skype integration, full control, easy (java applet on a web page, so zero-install)… HILARIOUSLY slow.
glance.net : seems to be share-only (no control), still quite slow, fairly easy setup, costs money
yuuguu.com: Slightly harder to setup, free, still horribly slow.
Screen sharing: cross-platform, very easy, small install: copilot.com. Cons: expensive, very very very slow.
Eventmachine for simple socket ruby apps.
You can’t override initialize with ActiveRecord models. Instead, use the after_initialize callback.
Fast Resume: before I leave, I write down whatever I was working on. When I start in the morning I can find my context much faster.
I always forget how to easily update multiple models in a single rails form. Here it is:
tumblr_is_stupid fields_for ‘hubbub[]’,u do |user_fields| tumblr_is_stupid
tumblr_is_stupid user_fields.check_box :is_admin tumblr_is_stupid
tumblr_is_stupid end tumblr_is_stupid
Hubbub.update(params[:hubbub].keys.collect{|k| k.to_i},params[:hubbub].values)
I’ve had to replace...

On OSX, mysql log files are in the mysql data dir, probably /usr/local/mysql/data . Look for a file ending in .err. You can’t see them in /var/log, or the system log viewer (which is called Console.app, for some reason).

(with instructions that are so good, I can follow them at 8am)
Using InnoDB, extended inserts (1000 records per instruction) are around 26 times faster than single inserts.
If you tell iTerm “unlimited scrollback buffer”, then run a 1000000 line .sql file inside a mysql shell, iTerm will use 1.5gb of memory and then crash. I want “[ ] unlimited scrollback, but don’t be stupid about it”
cd /usr/local/mysql; ./bin/mysqld_safe &
After a leopard install, your /etc/httpd.conf file is preserved but ignored. The real file is in /etc/apache2/httpd.conf. Note that spotlight won’t find this for you.
Leopard’s Terminal app finally supports tabs, but the tab name isn’t displayed in the tab (the command name is, instead). It’s no replacement for iterm.
Code formatting: Syntaxi / Syntax gem

Quicklook from command line:
cat ~/bin/ql
#!/bin/bash
qlmanage -p “$1” >& /dev/null
AAAH, but if you do that, when the app restarts all the stickies go back on the same space. No solution yet..
You can’t name leopard spaces, and you can’t use different backdrops. To tell them apart, put sticky notes on them using http://www.jimmcgowan.net/Site/StickEmUp.html

I was really trying to do the right thing. No wonder people pirate music.
To make any ruby script run in your rails environment, use script/runner, or add these lines to the top:
require File.dirname(__FILE__) + ‘/../config/boot’
require RAILS_ROOT + ‘/config/environment’
(You might need to do it that way if you’re using Daemonize)
