I am deserializing an object from a file that is 350KB in size, and its taking rather a long time. My computer science TA told me that there is a way to use a Buffered reader along with the ObjectInputStream to greatly increase performance. I however can not find anything about this on Google.

I have just finished the book "couchdb: a definitive guide" and started to play with design documents. there is however one thing, that I do not understand. All the examples I have seen so far are somewhat linear.

Example:

{
   "_id": "1",
   "_rev": ".....",
   "name": "first",
   "something": "blue",   
   "child": "2"   
}

{
   "_id": "2",
   "_rev": ".....",
   "name": "second",
   "something": "green",   
   "child": "3"   
   "parent" : "1"
   }

{
   "_id": "3",
   "_rev": ".....",
   "name": "second",
   "something": "red",   
   "parent" : "2";
}

I would like to ask if there's any Java package or library that have the standard URL normalization?

5 Components of URL Representation

http://www[dot]example[dot]com:8040/folder/exist?name=sky#head

1. scheme: http
2. authority: www.example.com:8040
3. path: /folder/exist
4. query: ?name=sky
5. fragment: #head

The 3 types of standard URL normalization

Syntax-Based Normalization

• Case normalization – convert all letter at scheme and authority components to lower case
• Percent-encoded normalization – decode any percent-encoded octet that corresponds to unreserved character, such as %2D for hyphen and %5 for underscore
• Path segment …

I'm stuck with a problem using jQuery Validate. The thing is I have a few textboxes with their maxlength attributes set. Although they are not required, they still fail to validate when either empty or whitespace.

Sample HTML:

<input type="textbox" id="tbx1" maxlength="100" value="" />

Then, $('#tbx1').valid() returns false. Shouldn't it return true instead? Are there any known workarounds for this?

Oh, and adding $('#myform').validate({ ignore: '#tbx1' }); doesn't quite work for me, because I'm using ASP.NET controls with their …

I am configuring Tomcat (5.5) server in Eclipse (3.3.2). Once I add Tomcat and start it, the output is printed in Eclipse Console. This output is printed in RED indicating its Standard Error. Although the server gets started without any error the normal INFO is also marked as error.

For example, if it's between 8 and 1 pm, it would say "good morning", if it's 1:01-6:00 pm, it would say "good afternoon" and if it's between 6:01-11:59, it would say "good evening"

How do I go about doing that using javascript/jquery?

I'm trying to develop a framework for several applications we are developing here and one of the framework classes I am trying to build is for creating a database. Ideally, I would have a method where I could pass it the following two methods: CreateDatabaseTables() and ResetDatabaseValues();

For instance, I might have three applications which I'll call Application1, Application2 and Application3; each one these applications would have a different database schema which I would incorporate into code (e.g. the CreateDatabaseTables …

In the following manifest, is it necessary to change the version attribute of the assemblyIdentity element if the assembly version is specified in the project (or, in my case, set as part of a MSBuild task)?

According to this Microsoft Connect page, it looks like the project's version number overrides the manifest's version number. Please correct me if I'm wrong...

<?xml version="1.0" encoding="utf-8"?>

比较多个数组并删除重复数据的最简单方法是什么？

所以(在这种情况下数组里面的数组)......

a = [[2, 1], [3, 3], [7, 2], [5, 6]]  
b = [[2, 1], [6, 7], [9, 9], [4, 3]]  
c = [[2, 1], [1, 1], [2, 2], [9, 9]]  
d = [[2, 1], [9, 9], [2, 2], [3, 1]]  

......会出来(优先考虑数组a,然后是b,然后是c,然后是d)

a = [[2, 1], [3, 3], [7, 2], [5, 6]]  
b = [[6, 7], [9, 9], [4, 3]]  
c = [[1, 1], [2, 2]]  
d = [[3, 1]]
