Add code formatter to your blog

see: http://code.google.com/p/syntaxhighlighter/

You could format ruby like this.

describe RSpec do
  before(:each) do
    @rspec = RSpec.new
  end

  describe "at release 1.0.8" do
    before(:each) do
      @rspec.version = "1.0.8" 
    end

    it "should not support nested example groups" do
      @rspec.should_not support_nested_example_groups
    end
  end

  describe "at release 1.1.0" do
    before(:each) do
      @rspec.version = "1.1.0" 
    end

    it "should support nested example groups" do
      @rspec.should support_nested_example_groups
    end
  end
end

Integrate your website with joblet seamlessly

For most of website that integrated joblet like asoboo. right now just link to http://asoboo.joblet.jp

But you may not want your user go out of your own domain. If you want to do so, You need to create a subdomain for you website, because things like http://asoboo.com/jobs simple not very easy to work. (all inside url of joblet is begain with / )

So For Apache, create a virtual host

ServerName jobs.asoboo.com

<Directory proxy:http://asoboo.joblet.jp>
    Order Allow,Deny
    Allow from all
</Directory>

ProxyPass / http://asoboo.joblet.jp/
ProxyPassReverse  / http://asoboo.joblet.jp/

And Then you can point your browser to http://jobs.asoboo.com, :)

Merge a branch r123:569 to trunk subversion

svn log --stop-on-copy http://svnserver/code/some_project/branches/release_12

to find out when the branch created, you know that at 942 revision, you created the branch

svn merge http://svnserver/code/some_project/branches/release_12 -r942:HEAD .

Run single test passed, but run all tests as a whole will fail that test

In my situation

I didn't load required fixture on that failed test when run all tests as a whole
when I run that special single test, because you already run all tests before,
and in some tests It loaded the fixture that you special test needed, and didn't clear
test database when you only run that special test. So It pass.

Don't override to_json like this

I don't know why our project override this method
class String
def to_json
"'#{self}'"
end
end

Because of this , The RJS totally don't work
and You get "unterminated string literal" because of not escaped javascript.

Ways to run ruby tests

1. rake
2. rake -T test
3. ruby test/unit/product_test.rb
4. ruby test/unit/product_test.rb -v
5. ruby test/unit/product_test.rb -n /create/ -v
6. rake test:units TESTOPTS="-v -n/create/"

Possibility with scoped_proxy

class User < ActiveRecord::Base
scoped_proxy :admins, :find => { :conditions => ['role = ?', 'super_user'] }
scoped_proxy :has_login do |login|
{ :find => { :conditions => ['login = ?', login] } }
end
scoped_proxy :no_op do
nil
end
end

# This gives you the first administrator of the system
User.admins.find(:first)
# This counts the administrators
User.admins.count

# All users with a given login
User.has_login('foo').count
User.has_login('foo').find(:all, :order => 'created_at desc')

# And finally, I give you the no op
User.no_op.find(:all) # => User.find(:all)

psql: FATAL: IDENT authentication failed for user

Everytime I log in using normal user, I got this message:

$ psql -U gateadmin template1
psql: FATAL: IDENT authentication failed for user "gateadmin"

Why?

It looks like you would rather use password authentication than the
default IDENT-based auth (it's default in Debian distro of postgres
anyway). IDENT will only let you in when you do *not* use -U, ie,
your postgres user name is the same as your Unix user name. Change
this in pg_hba.conf, and don't forget to SIGHUP or restart the
postmaster afterwards.

regards, tom lane

Solution:

Just modify pg_hba.conf like this (change to trust)

local all trust
host all 127.0.0.1 255.255.255.255 trust

portupgrade moved from /usr/ports/sysutils/portupgrade to
/usr/ports/ports-mgmt/portupgrade, one way to fix this is:

cd /usr/ports/ports-mgmt/portupgrade
make clean all install

Or I think portupgrade -f portupgrade might do.

ssh login when Capistrano deployment failed with that message. Running
(on Mac OS):

$ ssh-agent bash
$ ssh-add
and then running cap tasks fixed the problem for now.
