Hello, i am new in programming under linux and trying to get working this code:
http://scaryreasoner.wordpress.com/2007/11/17/using-ld_preload-libraries-and-glibc-backtrace-function-for-debugging/
but getting error: "ERROR: ld.so: object 'libwrap_ioctl.so' from LD_PRELOAD cannot be preloaded: ignored."
what can cause it?
system - Archlinux, kernel 2.6.32
thank you for answers
upd1:
"Check with ldd libwrap_ioctl.so if some dependency of this library is missing."
checked. no, i have all needed libraries
My project is similar to:
Users search the name of a medicine from a table. Then touch the medicine he/she looked for . Then prospectus of that medicine will appear on the view... How should I keep prospectus of medicine?(prospectus of a medicine consists of several lines of text) SQLite or NSDictionary thing... I thought that NSDictionary will not go well with my need... Any answers ???
Its been mentioned in other answers about getting the same code running for both the def get(self) and the def post(self) for any given request. I was wondering what techniques people use, I was thinking of:
class ListSubs(webapp.RequestHandler):
def get(self):
self._run()
def post(self):
self._run()
def _run(self):
self.response.out.write("This works nicely!")
Hi ,I want to display the map in my application .First of all i want to know about map api key not creation .That means api key is system dependent or debugger like that please give me some answers for this .Thanks in advance
I'm working on a mock exam paper at the moment, however I have no set of correct answers and I'm not sure what the correct answer of this SQL query is.
Given a table:
foo, bar
a , 1
b , 3
a , 2
c , 1
and the query:
SELECT foo, sum(bar)
FROM table
GROUP BY foo
The two ways I can see this going are either:
a 3
a 3
b 3
c 1
or
a 3
b 3
c 1
Thanks.
I have this snippet
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|images|img|css|js|robots\.txt)
RewriteRule (.*) index.php?/$1 [L]
It won't allow me to access a file at website.com/js/main.php
but it will let me access index.php
According to my webhost, $1 is being called before it is set. Any solutions?
I'll accept answers when i get back tomorrow. Thank you!
These questions are a kind of game, and I did not find the solution for them.
It is possible to write ::: in C++ without using quotes or anything like this and the compiler will accept it (macros are prohibited too).
And the same is true for C# too, but in C#, you have to write ???.
I think C++ will use the :: scope operator and C# will use ? : , but I do not know the answers to them.
Any idea?
The issue I am having is:
How do I go from a variable pointing at an element to using CSS selectors?
I want to make this work:
function highlight(table)
{$(table " > :even").toggleClass('highlight');}
where table is a reference to a table element.
I don't want answers that tell me to use $('#table') because that defeats the point of the generality I am trying to make.
Thanks
I have been googling this question for some time but got no answers. What's the Apache process model?
By process model, I mean how Apache manage process or thread to handling HTTP request.
Does it fork one process for each HTTP request?
Does it have process/thread pool?
Can we config it?
Is there any online doc for such Apache details?
Hi,
I am aware that this is not a direct 'development' question but I need that info to test a development project, so I think someone could've hit similar problem.
I will test a software that runs a TCP server and according to sent commands replies some answers. I will test the software and do not want to write code if it doesn't work well. So I want to send those commands and test drive the server software.
How can I achieve this with a Linux box?
I have structure as shown in the fiddle http://jsfiddle.net/5LN7U/.

Basically its a table structure made using divs. The first column contains a long list of questions and the second column contains answers/multiple answers which can be quite big ( there has to be horizontal scrolling in the second column.)
The problem i am facing is when i scroll downwards the second column which has the horizontal scroll bar is also scrolling downward. I want horizontal scrollbar to be fixed there. as in it should be always fixed there no matter how much i scroll vertically.
Much Like Google Spreadsheets: where the first column stays fixed and there's horizontal scrolling on rest of the columns with over vertical scrolling for whole of the data.
I cannot used position fixed in the second column.
P.S : please no lectures on using div's for making a table structure. I have my own reasons.
and its kinda urgent. Thanks in advance.
Now that the MVC 2 framework has been out for a while, I'm finding it very difficult to find documentation & answers specific to MVC2.
What are some good sites specific to MVC2?
There´s any eclipse shortcut to stance a new object ?
For example. I would like to type:
Object zzz =
and it would complete for me this way:
Object zzz = new Object();
with void parameter of course.
I will wait answers.. thank you people.
I have this doubt, I've searched the web and the answers seem to be diversified. Is it better to use mysql_pconnect over mysql_connect when connecting to a database via PHP? I read that pconnect scales much better, but on the other hand, being a persistent connection... having 10 000 connections at the same time, all persistent, doesn't seem scalable to me.
Thanks in advance.
Some people are saying " stack variable store its value in HEAP ", and others saying " stack variable store store its value in DATA segment". I am totally confused with these conflict answers.
Where exactly static variable stores?. I am expecting an answer with standard reference ( text books, or good author tutorial).

What's means the sentence "In C, a structure member may be of any type except "function returning T" (for some type T)"
Thanks for all the answers!
Hi
I know the spec allows both ' and " as delimiters for attribute values, and I also know it's a good practice to always quote.
However I consider " being the cleaner way, maybe it's just me having grown up with C and C++' syntax.
What is the cleanest way of quoting attribute values and why? Please no subjective answers.
Seems easy but I just don't get any further:
Take this example:
local myTable = { 'a', 'b', 'c', 'd' }
print( myTable[ math.random( 0, #myTable - 1 ) ] )
Why doesn't it work?
Google seems to have no answers on this either
I know there have been tons of answers on this subject, but I still cannot get it to work at all. I've enabled AllowDrop on every control at every level of the application, and tried to catch DragEnter and Drop on every control to no avail. I can drag and drop items inside the application, but any time I try to bring something in from Windows Explorer or the desktop, etc. it gives me the No icon. Any ideas what I might be doing wrong?
I want to branch if a message-property-code does exist or not.
<g:if test="${message(code: 'default.code.foo')}">
true
</g:if><g:else>
false
</g:else>
should answer true if there a message property named default.code.foo and false if not.
It fails because it answers the code if there is no property for it.
I need to convert XML data to Java objects. What would be best practice to convert this XML data to object?
Idea is to fetch data via a web service (it doesn't use WSDL, just HTTP GET queries, so I cannot use any framework) and answers are in XML. What would be best practice to handle this situation?
I know it's a very vague question, but maybe the answers could act like a poll about what could possibly be the next big event in computer science. A new language ? A new technology ? A new architecture ? A new business model ?
Please provide details, what is it and why do you think it's going to rule the world.

I have a SQL table it has more than 1000000 rows, and I need to select with the query as you can see below:
SELECT DISTINCT TOP (200) COUNT(1) AS COUNT, KEYWORD
FROM QUERIES WITH(NOLOCK)
WHERE KEYWORD LIKE '%Something%'
GROUP BY KEYWORD ORDER BY 'COUNT' DESC
Could you please tell me how can I optimize it to speed up the execution process? Thank you for useful answers.
