How to recover the headset issue with the manner mode

HTC Touch Proでは、ヘッドセットが接続された状態ではマナーモードが設定できません。接続された状態で電源が切れ、OFFの状態でヘッドセットを抜くとWindows Mobile内での情報がちぐはぐになり、接続されていないにも関わらず、マナーモードに設定できない不具合があるようです。今日はこの状態から回復する方法を書いてみることにします。

ヘッドセットが手元にある場合は、再度抜き差しで元に戻すことができますが、手元にない場合回復する手段はレジストリをいじる以外にありません。以下のキーを1から0にすることで元に戻せます。

How to add a feature to spotlight a column search on ActiveScaffold

ActiveScaffold is really nice to build something with Ruby on Rails. that saves my time a lot. though it may requires extra internal knowledges to do something that it doesn't provide. even generally.

So this is just a tips to add a column-based search feature to the ActiveScaffold. you can just patch it out to lib/active_scaffold/actions/search.rb and/or live_search.rb, or add it to your controller where you want to enable this feature.

def do_search
  @query = params[:search].to_s.strip rescue ''

  unless @query.empty?
    tmpq = @query.split(' ')
    columns_query = {}
    tmpq.delete_if do |x|
      retval = false
      if x =~ /\A(.*):(.*)\Z/ then
        p = $1
        v = $2
        if !p.nil? && !p.empty? && !v.nil? && !v.empty? &&
       active_scaffold_config.columns.include?(p) then
          columns_query[p] = v
          retval = true
        end
      end
      retval
    end
   columns = active_scaffold_config.live_search.columns
   like_pattern = active_scaffold_config.live_search.full_text_search? ? '%?%' : '?%'
   search_conditions = self.class.create_conditions_for_columns(tmpq, columns, like_pattern)
    self.active_scaffold_conditions = merge_conditions(self.active_scaffold_conditions, search_conditions)
    columns_query.each do |p,v|
      active_scaffold_config.columns.each do |column|
        next if column.column.nil?
        if column.column.name == p then
          sql = column.column.text? ? "LOWER(#{column.search_sql}) LIKE ?" : "#{column.search_sql} = ?"
          token = column.column.text? ? like_pattern.sub('?', v.downcase) : column.column.type_cast(v)
          self.active_scaffold_conditions = merge_conditions(self.active_scaffold_conditions, [sql, token])
          break
        end
      end
    end
    @filtered = !search_conditions.blank?

   includes_for_search_columns = columns.collect{ |column| column.includes}.flatten.uniq.compact
    self.active_scaffold_joins.concat includes_for_search_columns

   active_scaffold_config.list.user.page = nil
  end
end

How to get rid of the line separators on Today

From Xda-developers:

Code:

REGEDIT4
[HKEY_LOCAL_MACHINE\Software\Microsoft\Today]
"HidePluginSeparators"=dword:1

It works fine on HT-01A too. though I may want to update my Today. it looks not so sweet unfortunately..

How to enable fingerprint reader on Fedora 11

Although you could do use the fingerprint reader with thinkfinger package if it supports your device, this is a new feature available since Fedora 11, which is well integrated to the desktop and more convenient.

It's available without taking any actions if you install Fedora 11 freshly. otherwise you just need to install some packages like:

• fprintd
• fprintd-pam
• gdm-plugin-fingerprint

After that, enable the feature with system-config-authentication. go to the Authentication tab and turn on the "Enable Fingerprint Reader Support".

To register your fingerprint, run gnome-about-me or "About Me" from System->Settings at the panel. and click a "Enable Fingerprint Login..." button. follow the wizard to complete the fingerprint registration. you need to place your finger on the reader 3 times to ensure if it reads correctly.

Once the registration is successfully finished, authentications for, such as login, sudo, screensaver and so on will be done through your fingerprint reader device then. pretty easy :)

Enjoy!
