What are the Pros/Cons of the different D Compilers? How is the performance and the standard compliance/D2 support? How well are debuggers supported? How good are the Error messages and is the IDE integration? How good is the 64 bit support? My thought so far:

**DMD**

 - Mature and well maintained
 - Only one platform, 64 bit support is not good
 - Not FOSS


**GDC**

 - Supports various platforms
 - Has very mature optimizations, so it&#39;s fast?
 - Out of date runtime?
 - GCC so a good debugger support?


**LDC**

 - Supports various platforms
 - LLVM, so it supports JITing?
 - Has very mature optimizations, so it&#39;s fast?
 - Not very well maintained?
 - Out of date runtime?

**dead/not working**
 
 -  dang
 -  sdc
 -  MiniD - very, very nice, but not D (never claimed to be, though)

I&#39;m thinking about targeting ARM and i think GDC is the tool of choice, but I&#39;m not sure.

The 1st snippet wasn&#39;t working. However, it start working when replacing all **$**(dollar sign) with **jQuery**(See 2nd snippet). But i don&#39;t really understant why? Can anyone explain this to me? Many thanks!

**1st Snippet**
               

    jQuery.noConflict();
                   $(document).ready(function(){    
                        $(&quot;#insideTable &gt; tbody &gt; tr:odd&quot;).addClass(&quot;odd&quot;);
                        $(&quot;#insideTable &gt; tbody &gt; tr:not(.odd)&quot;).hide();
                        $(&quot;#insideTable &gt; tbody &gt; tr:odd&quot;).show();
                        $(&quot;#insideTable &gt; tbody &gt; tr.odd&quot;).click(function(){
                            $(this).next().toggle();
                            $(this).find(&quot;.arrow&quot;).toggleClass(&quot;up&quot;);
                        });
    
                    });

**2nd Snippet**

            jQuery.noConflict();
            jQuery(document).ready(function(){

                    jQuery(&quot;#insideTable &gt; tbody &gt; tr:odd&quot;).addClass(&quot;odd&quot;);
                    jQuery(&quot;#insideTable &gt; tbody &gt; tr:not(.odd)&quot;).hide();
                    jQuery(&quot;#insideTable &gt; tbody &gt; tr:odd&quot;).show();
                    jQuery(&quot;#insideTable &gt; tbody &gt; tr.odd&quot;).click(function(){
                        jQuery(this).next().toggle();
                        jQuery(this).find(&quot;.arrow&quot;).toggleClass(&quot;up&quot;);
                    });

                });

I am aware of how i18n/l10n is usually done in Rails3, and I chose to have a single ERB file that calls `t(...)` for localization. But for a particular part I need something special:

I need to display a string whose &lt;b&gt;localization is coming from an external database&lt;/b&gt;.

So how can I know the current language, to call the external database with an `en` or `ja` parameter?

Something like $LANG in UNIX. Preferably accessible from view or controller.

Is there an alternative to `update_attributes` that does not save the record?

So I could do something like:

    @car = Car.new(:make =&gt; &#39;GMC&#39;)
    #other processing
    @car.update_attributes(:model =&gt; &#39;Sierra&#39;, :year =&gt; &quot;2012&quot;, :looks =&gt; &quot;Super Sexy, wanna make love to it&quot;)
    #other processing
    @car.save

BTW, I know I can `@car.model = &#39;Sierra&#39;`, but I want to update them all on one line.

I recently upgraded to OSX 10.7, at which point my rails installation completely borked when trying to connect to the psql server.   When I do it from the command line using 

    psql -U postgres

it works totally fine, but when I try to run the rails server or console with the same username and password, I get this error 

    ...activerecord-3.0.9/lib/active_record/connection_adapters/postgresql_adapter.rb:950:in `initialize&#39;: could not connect to server: Permission denied (PGError)	
    Is the server running locally and accepting
    	connections on Unix domain socket &quot;/var/pgsql_socket/.s.PGSQL.5432&quot;?

Any ideas what might be going on would be super helpful!  Thanks!

I am using Ruby on Rails 3.0.9 and I would like to check if a number is included in a range. That is, if I have a variable `number = 5` I would like to check `1 &lt;= number &lt;= 10` and retrieve a boolean value if the `number` value is included in that range.

I can do that like this:

    number &gt;= 1 &amp;&amp; number &lt;= 10

but I would like to do that in one statement. How can I do that?

In Django templates, you can use either `{{ _(&quot;Hello World&quot;) }}` or `{% trans &quot;Hello World&quot; %}` to mark strings to be translated. In docs, the “official” approach seems to be the [`{% trans %}`](https://docs.djangoproject.com/en/1.8/topics/i18n/translation/#trans-template-tag) tag, but the `_()` syntax is mentioned too [once](https://docs.djangoproject.com/en/1.8/topics/i18n/translation/#string-literals-passed-to-tags-and-filters).

**How these approaches differ** (except syntax) and why should be one preferable rather than the other?

One difference is that you obviously can&#39;t use `{% trans %}` with tags and filters. But does that mean that I can just use `_()` everywhere, like `{{ _(&quot;String&quot;) }}`? It works and looks much cleaner and more consistent than using `{% trans &quot;String&quot; %}` with standalone strings and `_()` with tags and filters.

I want to know what the current day of the week is (Monday, Tuesday...) in the user&#39;s local language. For example, &quot;Lundi&quot; &quot;Mardi&quot; etc... if the user is French. 

I have read this post, it but it only returns an int, not a string with the day in the user&#39;s language: https://stackoverflow.com/questions/5574673/what-is-the-easiest-way-to-get-the-current-day-of-the-week-in-android

More generally, how do you get all the days of the week and all the months of the year written in the user&#39;s language ? 

I think that this is possible, as for example the Google agenda gives the days and months written in the user&#39;s local language.

I&#39;m currently using Handlebars.js (associated with Backbone and jQuery) to make a web app almost totally client side rendered, and I&#39;m having issues with the internationalisation of this app.

How can I make this work?

Are there any plugins?

            android:layout_weight=&quot;1&quot;/&gt;
      &lt;/LinearLayout&gt;
    
    &lt;/LinearLayout&gt;

And, I noticed :    
1) yellow line under **`android:text=&quot;Yellow&quot;`**    
2) yellow line under **`android:text=&quot;row four&quot;`**    
the Triangle warn says ` [I18N] Hardcoded string &quot;Yellow&quot;, should use @string resource &quot;`
and same for the rest of the warnings.Any suggestion?
