Use Fiddler with Firefox
The FireBug console is a plug-in to the Firefox browser, and it is window based, which I guess each tab will have a different FireBug instances for monitoring the HTTP traffic. So there is no central place for monitoring HTTP traffic from all opened browser windows. If something goes wrong in the window, which is then closed, the record for the HTTP traffic before the error occurs will be missing. By letting the Fiddler monitor the HTTP traffic in your Firfox browser will avoid this issue.
Fidder works very well with IE browser and no effort will be required to let Fiddler monitors the HTTP traffic in the IE browser. For Firefox, you need to
* Open options from the Tool menu item and click Advanced tab
* Go to Network | Connection Settings
* Use the Manual proxy configuration option
* Set Http proxy to 127.0.0.1 and Port 8888

Adding Google Prettifier to Blogger
Goto dashboard, and click Editing HTML under the Layout tag, add the following two lines in the <head> tag
<link href="http://xxx.org/prettify.css" type="text/css" rel="stylesheet" />
<script type="text/javascript" src="http://xxx.org/prettify.js"></script>
The next thing is to find the <body> tag and change it to
<body onload='prettyPrint()'>
Ok, you are done and you can create a post testing this feature. For example, creating a post with the following code
<pre class='prettyprint'>
class Voila {
public:
// Voila
static const string VOILA = "Voila";
// will not interfere with embedded tags.
}
</pre>
and here is the result
class Voila {
public:
// Voila
static const string VOILA = "Voila";
// will not interfere with embedded tags.
}
PS: Made some improvement to the prettify style and add overflow: auto; for pre.prettyprint
pre.prettyprint { padding: 2px; border: 1px solid #888; overflow: auto;}

Create summaries for the blog posts
In blogger Dashboard, click layout and select 'Edit HTML' tab. The first thing you need to do is to download the full copy of the template in case you mess up something with the template. At least, you can recover it by uploading the full copy. The template should be a xml file. Please make a copy before any further action.
Now open the xml file in your favored editor, since I am using the layout template, I have to add the following style definition into <header>
<b:if cond="data:blog.pageType == "item"">
span.fullpost {display:inline;}
<b:else>
span.fullpost {display:none;}
</b:else>
In my template, there is a big section for <b:skin> tag in the header, so I placed the code above just after it and before the end of <head>. This actually defines the style for class fullpost of span tag. If all blogs are on the same page, any texts of class fullpost will be hidden; otherwise, they will be displayed.
The next thing is to enable the summaries ("Read More" link at the end of the blog) when your blog posts are listed on the page.
</b:skin></b:if><div class="post-body entry-content">
<p>
<data:post.body>
<!--add for blog summary-->
<b:if cond="data:blog.pageType != "item"">
<a href="data:post.url">Read more!</a>
</b:if>
<!--end-->
</data:post.body></p>
<div style="clear: both;"> <!-- clear for photos floats -->
</div>
Finally, you need to specify which part of the blog will be hidden. You can use <span> tag (<div> tag doesn't work). Please refer to the help for more information or check this post itself.

Oracle Text -- FILE_DATASTORAGE
There is a default FILE_DATASTORAGE preference by Oracle Text, but you have to specify the full path in the text table for the files that you want Oracle Text to index. However, you can create your own FILE_DATASTORAGE and set the path attribute for the preference and only specify the file name in the text table.
BEGIN
CTX_DDL.CREATE_PREFERENCE('my_datastorage', 'FILE_DATASTROAGE');
CTX_DDL.SET_ATTRIBUTE('my_datastorage','path', '/home/doc');
END
it is not allowed to give a partial path in the text table if you specify the path attribute for the FILE_DATASTORAGE preference. The location in the text table is either just file name or a full path for the file. If it is just file name, Oracle Text should looks up all paths in the path attribute of the preference and search for files with the specified name. So it may not be a good idea to use this if there are files with same names. If path is specified, it might be ignored if path is set for the preference. It will be helpful if Oracle Text doesn't accept partial path in the text table.
Here is the scenario that partial path might be helping. It is probably that the whole file set may be placed at different locations. If Oracle Text supports partial path in the text table, it is possible for Oracle to index two file sets with one table (and index) by creating another FILE_DATASTORAGE preference (this should be working if your file set is just plain files under the root directory).
BEGIN
CTX_DDL.CREATE_PREFERENCE('my_datastorage1', 'FILE_DATASTROAGE');
CTX_DDL.SET_ATTRIBUTE('my_datastorage','path', '/home/doc_copy');
END
and the text table specify the relative path for files under /home/doc_copy or /home/doc, so they can share the same text table and index, but just change the meta data for the index every time when you try to synchronize the index.
Note: This is just my thought and haven't try to test this and measure its performance if you change the FILE_DATASTORAGE every time you try to synchronize the index.
