In a code example I saw, the author uses StringBuffer with append method instead of String with + operator. What is the point here? Does StringBuffer have an advantage?
I want to define the block as a string, then create the lambda.
The following example does not work.
Is something like this possible?
code_string = "|x|x*2"
l = lambda {eval(code_string)}
l.call(3) => 6
I'm somewhat new to objective-c and I'm not sure what the correct memory management for this code is.
const unsigned char * data =(const unsigned char *) [string UTF8String];
When I call free on data I get an error. Do I need to clean up after this call?
thanks!

According to CI's docs, CodeIgniter uses a segment-based approach, for example:
example.com/my/group
If I want to find a specific group (id=5), I can visit
example.com/my/group/5
And in the controller, define
function group($id='') {
...
}
Now I want to use the traditional approach, which CI calls "query string" URL. Example:
example.com/my/group?id=5
If I go to this URL directly, I get a 404 page not found. So how can I enable this?
std::string x(x);
This crashes very badly on my compiler. Does this mean I should test for this != &that in my own copy constructors, or can I assume that no client will ever be so stupid?
I have a long int variable that I need to convert to a signed 32bit hexadecimal string (8 characters) (char array) without the "0x" at the start?
How would I go about doing this?
Thanks.

My emacs hangs (Ubuntu 9 + emacs 23 + pyflakes) when I type """ quotes for string blocks.
anybody experience the same problem? I think, it may not be the emacs problem but some python mode or pyflakes which I use it for error checking.
Anybody hot around the issue? It really frustrating experience.

I'm building a application that needs to convert a ResultSet String(rs.getString(Names);) into a workable variable to populate a jTable, only one collumn, then the rest I think that I could try by doing a loop.
How could I do this?
Hey guys,
How do I go about setting a string as a literal variable in PHP? Basically I have an array like
$data['setting'] = "thevalue";
and I want to convert that 'setting' to $setting so that $setting becomes "thevalue".
Thanks for any help!
I need something similar to List<String, Int32, Int32>. List only supports one type at a time, and Dictionary only two at a time. Is there a clean way to do something like the above (a multidimensional generic list/collection)?
I have the following line of code.
<%= Html.Encode(string.Join(", ", item.company1.companies.Select(x => x.company_name).ToArray())) %>
Would it be possible to somehow replace the comma with a line break?
Is there a way in objective-c/Cocoa to alloc an object when the class name isn't know until run-time. I seem to remember something about this a while ago, but can't find anything on it now.
Something like:
[[@"MyClass" alloc] init];
I seem to recall a function that would return some kind of class id based on a string that can then be used to alloc the object.
I have a list that has some chapter numbers in string.
When I sort the keys using keys function, it gives me wrong results.
keys = ['1.1', '1.2', '2.1', '10.1']
keys.sort()
print keys
['1.1', '1.2', '10.1', '2.1']
How can I use the sort function to get
['1.1', '1.2', '2.1', '10.1']
What if the array has something like this?
['1.1.1', '1.2.1', '10.1', '2.1'] - ['1.1.1','1.2.1','2.1','10.1']
Assume:
Elf_Section_Header *sectionHeaderTable //points to the start of a ELF section header table
Elf_Section_Header *symtabHeader //points to the start of the symtab section header
Why doesn't the following point me to the associated string table section header?
Elf_Section_Header *strTabSectionHeader = (Elf_Section_Header *)((char *)sectionHeaderTable + (symtabHeader-strtab_index));
'strTabSectionHeader-type == SHT_STRTAB' is equal to false
How should I point ot the strTabSectionHeader?
Suppose I have a string that contains '¿'. How would I find all those unicode characters? Should I test for their code? How would I do that?
I want to detect it to avoid sax parser exception which I am getting it while parsing the xml
saved as a clob in oracle 10g database.
Exception
javax.servlet.ServletException: org.xml.sax.SAXParseException: Invalid byte 1 of 1-byte UTF-8 sequence.
I'm working with a database that has a bunch of serial numbers that are prefixed with leading 0's.
So a serial number can look like 00032432 or 56332432.
Problem is with PHP I don't understand how the conversion system with octals works.
A specific example is that I'm trying to convert and compare all of these integer based numbers with strings.
Is it possible to convert an octal, such as 00234 to a string like "00234" so that I can compare it?

How to validate a substring is true in PHP for example if user1 is in the string it should be true?

Hi,
I am not so good with regex. I am struggling to find a solution for a small functionality.
I have a ajax response which returns a string like "Your ticket has been successfully logged. Please follow the link to view details 123432."
All I have to do is replace that number 123432 with <a href="blablabla.com?ticket=123432"> using javascript.
