    strstr(request, &quot;favicon&quot;) != NULL

The basic Google search [bigobj issue](https://www.google.com/search?q=bigobj+issue) shows that a lot of people are experiencing the [Fatal Error C1128](http://msdn.microsoft.com/en-us/library/8578y171.aspx): &quot;*number of sections exceeded object file format limit : compile with /bigobj*&quot;. The error has more chance to occur if one heavily uses a library of C++ templates, like [Boost libraries](http://www.boost.org) or [CGAL libraries](http://www.cgal.org/).

That error is strange, because it gives the solution to itself: set the [compiler flag `/bigobj`](http://msdn.microsoft.com/en-us/library/ms173499.aspx)!

So here is my question: why is not that flag set by default? There must be a penalty of using that flag, otherwise it would be set by default. That penalty is not documented in MSDN. Does anybody have a clue?

I ask the question because I wonder if the configuration system of [CGAL](http://www.cgal.org) should not set `/bigobj` by default.

I am beginner to spring, ESP Inversion of control. I was puzzled understanding the difference between the following 


     &lt;bean id=&quot;demo&quot; class=&quot;Demo&quot; lazy-init=&quot;false&quot;/&gt;
     &lt;bean id=&quot;demo&quot; class=&quot;Demo&quot; lazy-init=&quot;true&quot;/&gt;
     &lt;bean id=&quot;demo&quot; class=&quot;Demo&quot; lazy-init=&quot;default&quot;/&gt;

To my understanding : lazy-init=false creates the bean at the startup and lazy-init=true doesn&#39;t create a bean at the startup rather creates the bean upon request for a particular bean.
Correct me here, If my interpretation is wrong.

what exactly the default behavior of lazy-init is? How would it instantiate?

I&#39;m pretty new to the language. Let&#39;s say I have a string from an HTTP request, such as

    char * request = &quot;GET /favicon.ico HTTP/1.1&quot;;

And I specifically want to know if `favicon` is in that request, perhaps with a boolean value. What is a relatively simple way to go about this? I know how to do it in Java, but I&#39;m more lost with C.

Thanks!

I have a small question.  I know that the %x format specifier can be used to read values from the stack in a format string attack.

I found the following code:

    %08x%08x%08x%08x

What does the 08 mean?  What is it doing exactly?  Thanks :)

I was just going through some code on the Internet and found this:

    float * (*(*foo())[SIZE][SIZE])()

How do I read this declaration? Is there a specific set of rules for reading such complex declarations?

In a reputable source about C, the following information is given after discussing the `&amp;` operator:

&gt; ... It&#39;s a bit unfortunate that the terminology *[address of]* remains, because it confuses those who don&#39;t know what addresses are about, and misleads those who do: thinking about pointers as if they were addresses usually leads to grief...

Other materials I have read (from equally reputable sources, I would say) have always unabashedly referred to pointers and the `&amp;` operator as giving memory addresses. **I would love to keep searching for the actuality of the matter, but it is kind of difficult when reputable sources KIND OF disagree.**

Now I am slightly confused--what *exactly* is a pointer, then, if not a memory address? 

**P.S.**

The author later says: *...I will continue to use the term &#39;address of&#39; though, because to invent a different one* [term] *would be even worse.*

In Java for String class there is a method called matches, how to use this method to check if my string is having only digits using regular expression. I tried with below examples, but both of them returned me false as result.

    String regex = &quot;[0-9]&quot;;
    String data = &quot;23343453&quot;;
    System.out.println(data.matches(regex));

-------------------------

    String regex = &quot;^[0-9]&quot;;
    String data = &quot;23343453&quot;;
    System.out.println(data.matches(regex));

I want to check if a String contains the words &quot;stores&quot;, &quot;store&quot;, and &quot;product&quot; in that order, no matter what is in between them.

I tried using `someString.contains(stores%store%product);` and also `.contains(&quot;stores%store%product&quot;);`

Do I need to explicitly declare a regex and pass it on the method or can I not pass a regex at all?

From https://stackoverflow.com/questions/12118720/python-tf-idf-cosine-to-find-document-similarity , it is possible to calculate document similarity using tf-idf cosine. Without importing external libraries, are that any ways to calculate cosine similarity between 2 strings?


    s1 = &quot;This is a foo bar sentence .&quot;
    s2 = &quot;This sentence is similar to a foo bar sentence .&quot;
    s3 = &quot;What is this string ? Totally not related to the other two lines .&quot;
    
    cosine_sim(s1, s2) # Should give high cosine similarity
    cosine_sim(s1, s3) # Shouldn&#39;t give high cosine similarity value
    cosine_sim(s2, s3) # Shouldn&#39;t give high cosine similarity value

Assuming I have a String `string` like this:

    &quot;abcd=0; efgh=1&quot;

and I want to replace &quot;abcd&quot; by &quot;dddd&quot;. I have tried to do such thing:

    string.replaceAll(&quot;abcd&quot;,&quot;dddd&quot;);

It does not work. Any suggestions? 

EDIT:
To be more specific, I am working in Java and I am trying to parse the HTML document, concretely the content between `&lt;script&gt;` tags. I have already found a way how to parse this content into a string:

     if(tag instanceof ScriptTag){
    	    if(((ScriptTag) tag).getStringText().contains(&quot;DataVideo&quot;)){
    	    	String tagText = ((ScriptTag)tag).getStringText();
          }
    }

Now I have to find a way how to replace one substring by another one. 

How to replace a substring of a string

I want to format this date: `&lt;div id=&quot;date&quot;&gt;23/05/2013&lt;/div&gt;`.

First I want to split the string at the first `/` and have the rest in the next line. Next, I’d like to surround the first part in a `&lt;span&gt;` tag, as follows:

    &lt;div id=&quot;date&quot;&gt;
    &lt;span&gt;23&lt;/span&gt;
    05/2013&lt;/div&gt;

&lt;!-- language-all: none --&gt;

&gt;     23
&gt;     05/2013

What I did:


&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-html --&gt;

    &lt;script src=&quot;https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js&quot;&gt;&lt;/script&gt;

    &lt;div id=&quot;date&quot;&gt;23/05/2013&lt;/div&gt;
    &lt;script type=&quot;text/javascript&quot;&gt;
      $(document).ready(function() {
        $(&quot;#date&quot;).text().substring(0, 2) + &#39;&lt;br /&gt;&#39;;
      });
    &lt;/script&gt;

&lt;!-- end snippet --&gt;

See the [JSFiddle](http://jsfiddle.net/K3D6d/).

But this does not work. Can someone help me with jQuery?

I&#39;ve got dirty data in a column with variable alpha length. I just want to strip out anything that is not 0-9. 

I do not want to run a function or proc. I have a script that is similar that just grabs the numeric value after text, it looks like this:

    Update TableName
    set ColumntoUpdate=cast(replace(Columnofdirtydata,&#39;Alpha #&#39;,&#39;&#39;) as int)
    where Columnofdirtydata like &#39;Alpha #%&#39;
    And ColumntoUpdate is Null

I thought it would work pretty good until I found that some of the data fields I thought would just be in the format Alpha # 12345789 are not. 

Examples of data that needs to be stripped

    AB ABCDE # 123
    ABCDE# 123
    AB: ABC# 123

I just want the 123. It is true that all data fields do have the # prior to the number. 

I tried substring and PatIndex, but I&#39;m not quite getting the syntax correct or something. Anyone have any advice on the best way to address this?

Select query to remove non-numeric characters

We are given a string, say, `&quot;itiswhatitis&quot;` and a substring, say, `&quot;is&quot;`.
I need to find the index of `&#39;i&#39;` when the string `&quot;is&quot;` occurs a second time in the original string.

`String.indexOf(&quot;is&quot;)` will return 2 in this case. I want the output to be 10 in this case.

Finding second occurrence of a substring in a string in Java

The Pythonic way to check if a string `x` is a substring of `y` is:

    if x in y:

Finding if `x` is equivalent to `a`, `b`, `c`, `d`, `e`, `f` or `g` is also Pythonic:

    if x in [a,b,c,d,e,f,g]:

But checking if some string `x` contains either `a`, `b`, `c`, `d`, `e`, `f` or `g` seems clunky:

    if a in x or b in x or c in x or d in x or e in x or f in x or g in x

Is there a more **Pythonic** method of checking if a string `x` contains an element of a list?

I know it is trivial to write this myself using a loop or using a regex:

    re.search(&#39;(dog|cat|bird|mouse|elephant|pig|cow)&#39;, x)

but I was wondering if there was a cleaner way that does not involve regex.
