I have the same feeling after I tried git. Some guy told me Mercurial is worth a try and other guys told me bzr is cool. They are all DVCS.

It's pity to see XRuby is fading away ...

Most articles on the web give ppl an impression that habtm(has_and_belongs_to_many) is outdated and you should use has_many :through in many-to-many relationship between ActiveRecord models. I'd say that's wrong.

In fact habtm is more closer to has_many without :through than has_many :through, like it will add #{collection}_ids method but has_many :through won't. And habtm is NOT outdated, has_many :through is not a replacement of habtm. You should restrict yourself to use has_many :through only when you have to model the join table in the middle, in any other case, habtm is the better choice.

ActsAsOptions
=============

This plugin make model acts like select options

Installation
------------

In your rails directory:

script/plugin install http://janx.googlecode.com/svn/trunk/acts_as_options

How To Use
----------

After installed, add the 'acts_as_options' line to your model:

class Brand
  acts_as_options
end

By default ActsAsOptions suppose you have a 'name' column and a 'id' column in your table, you can change this of course(see below).

After the declaration whenever you need options for a select in form, simply:

f.select :brands, Brand.find_as_options
or
select_tag :brands, Brand.find_as_options

you can specify the name and value column when declaration or find:

acts_as_options :stub, :id # will generate <option value='<%= brand.id %>'><%= brand.stub %></option>
Brand.find_as_options :stub, :id

I'm glad to annouce the new boring/repetitititititititititititive tool: urlview.rb. It will help u to extract urls out from a paragraph and provides a very light curses based UI for u to open the url in your favorate browser. You can try it like this:

./urlview.rb urlview.rb
or
cat urlview.rb | urlview.rb

I hope it will be loved by the ppl who is both a rubist and mutt user :-)  When use with mutt like this u can use C-b to open links in mail:

macro pager \cb <pipe-entry>'<PATH TO URLVIEW.RB>'<enter> 'Follow links with urlview'

enjoy.

wmii is cool since it's configurable with *ANY* language. As a rubist I use ruby-wmii by Mauricio (who is well known as mfp).

One problem is you can't assign shortcuts to resize a window in the latest wmii release. I asked for this in wmii's mailing list and luckily Kris, the author of wmii, quickly replied and implemented this. It's great, but the new problem is I found that WMII_ADDRESS, a environment variable, which will be set when wmii start in latestest stable release, does no longer exist in development version. And ruby-wmii will ask for it when wmii starts, so in one sentence, wmii version 'hg2307+' won't work with ruby-wmii.

Have no time to dig more, just create a quick patch to fix this:

around line#96 In cmd/wmii/main.c

Original:

    if(address)
        setenv("WMII_ADDRESS", address, true);
    else
        address = smprint("unix!%s/wmii", ns_path);

To:

    if(!address)
        address = smprint("unix!%s/wmii", ns_path);

    setenv("WMII_ADDRESS", address, true);

May post a better solution later.

To make chinese songs shows correctly in mpd, add these two lines in your mpd.conf

filesystem_charset              "UTF8"
id3v1_encoding                  "UTF8"

Now you should be able to see familiar characters in Sonata. Further, if you want chinese work in ncmpc, try this:

sudo cp /usr/lib/libncursesw.so.5.6 /usr/lib/libncurses.so.5.6

* Your terminal should be configured correctly to display chinese characters
