Is there any compare operator in c# like SQL's IN statement
This is not a specific question but a generic question which was in my mind from long time
I have to check one variable if it contains a value from a list of strings
for e.g.
status == "Open" && status =="Active" && status =="Reopen" && status = "InActive etc..
In SQL it is very easy to write this kind of statements e.g.
select * from ticket where status in ("Open","Active","Reopen","InActive)
I wonder we don't have such easy statement in C#?
Do anybody know any easy way like SQL to write this kind of statements without using generic types of if else ,foreach loop etc..

Compare Two arrays and merging in PHP
I have two arrays :
$array1 = array(1=>1,10=>1,12=>0,13=>13);
$array2 = array(1=>"Hello",10=>"Test",12=>"check",13=>"error");
Here $array1 have keys and values.Now i want to take first value from $array1(as 1) and want to check if this is repeated in this array .
Here 1 is repeated two times so i want to take the twp keys 1,10 and display the corresponding values of this keys from $array2.If the value in $array1 not repeated just display the value of this key from $array2.
That is i want to get the output as :
Hello Test
check
error
That means ,
In $array1 1,10 keys have same value so value of 1 and 10 from $array2 is merged.then displayed.
Like 12 ,have 0 this is not repeated so simply take value of 12 from $array2.
Like 13.
How can i do this?

Hi i am trying to write simple game where there is one player and some simple world like trees or some buildings, player can walk having muchine gun and shoot to world object like trees and finally destroy it, view is from the top so i don't need any gravity.

Also important is that player can't now walk on other object, like there is a monster and player and they can't exist in the same place (one shouldn't go on another). Can you recoment me some collision detection engine or better I should write it my self?

C/C++ MultiMap Library
I have store 111 million key-value pairs (one key can have multiple values - maximum 2/3) whose key are 50 bit Integers and values are 32 bit (maximum) Integers. Now, my requirements are:
- Fast Insertion of (Key, Value) pair [allowing duplicates]
- Fast retrieving of value/values based on key.
Is there any library for C/C++ which solves this issue ? I can provide 5/6 GB main memory for that. For more info: my previous post.

PHPUnit Fatal Error with Selenium/Ubuntu
I have gone through various tutorials/posts to install PHPUnit with Selenium on my Ubuntu system. I believe I have everything setup as required:
/usr/share/php$ phpunit --version
PHPUnit 3.6.10 by Sebastian Bergmann.
So using the IDE I create my test, and save it for running, which appears to be setup as required. So I run the test using:
phpunit /home/retrobadger/working_files/tutorials/phpunit/selenium1.php
But everytime I run it, I get the error below:
PHP Fatal error: Class 'PHPUnit_Extensions_SeleniumTestSuite' not found in /usr/share/php/PHPUnit/Extensions/SeleniumTestCase.php on line 394
PHP Stack trace:
PHP 1. {main}() /usr/bin/phpunit:0
PHP 2. PHPUnit_TextUI_Command::main() /usr/bin/phpunit:46
PHP 3. PHPUnit_TextUI_Command->run() /usr/share/php/PHPUnit/TextUI/Command.php:130
PHP 4. PHPUnit_Runner_BaseTestRunner->getTest() /usr/share/php/PHPUnit/TextUI/Command.php:150
PHP 5. ReflectionMethod->invoke() /usr/share/php/PHPUnit/Runner/BaseTestRunner.php:124
PHP 6. PHPUnit_Extensions_SeleniumTestCase::suite() /usr/share/php/PHPUnit/Extensions/SeleniumTestCase.php:0
The file in extensions exists, and I have set very open priviledges to it. The only things I can think of are that either my SeleniumTestCase.php is faulty, or that I need to require another file no other tutorials have suggested.
Any recommendations would be greatly appreciated. I have little experience with PHPUnit so expect my mistake is a basic one.
Thanks for any advice you can give,
Dan
xcode UIWebView loader code HTML
I've a question about load inside the web view:
I create a Json file to get Wordpress table and work well but inside the content table i can get only pure HTML code in one Line, so if i do a request from the web view to load the content like standard code i can't see the content, but only pure code with tags:
[MyWeview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:MyJsonClass.MyContentTeble ]]];
This normal code working, but not to encode HTML, how can encode the HTML directly inside the web view?
Thanks for help.
How to make expect command in expect program script to wait for exact string matching
I want to know how to make expect command in expect script to wait for exact string to be matched before proceeding to next line in the script.
The code is as shown below
#!/bin/sh
#!/usr/bin/expect
spawn ssh -Y localuser@lbblr-tirumala
expect -exact "localuser@lbblr-tirumala's password: "
# replace password with ur own passwd
send "geomax45\r"
# replace the prompt with ur own prompt
expect "localuser@lbblr-tirumala:~$ "
# run application
send "./sample\r"
expect "*Menu*\r
1. print hello world\r
2. print Bye world\r
3. quit\r
enter choice: "
# enter choice 1
send "1\r"
expect "Bye world\r
*Menu*\r
1. print hello world\r
2. print Bye world\r
3. quit\r
enter choice: $"
# enter choice 2
send "2\r"
In the above code after entering 1 the code should wait for "Bye world\r......" string to occur on the screen. But even though the screen prompts different string altogether, the code is executing the mext line and entering option 2, which should not occur as per definition of expect. It should wait untill the complete string in expect command matches.
I want to know whether there is any stricter command that can be used so that expect waits until exact string matching occurs. Please help me in this issue

Timeline Chart framework, Flotr vs AmChart
I have been comparing many chart framework, and these two are the final contenders. There is no point to compare frameworks if there are no specifications. So, I will lay down my specifications and hope to have some responses, would be valuable to people having questions on which framework they should choose.
Final Goal : Stock Chart just like Google Finance
Points of interest
1. No Flash, for mobile device compatibility
2. No Charge (HighCharts is cool if you have money)
3. Annotation on Chart, for marking events
4. Zoom in/ Zoom out
5. Multiple Y-axes
Where do you think?

Ruby: Cryptographically sign a string to ensure authenticity?
Lets say I have a origin server which through the act of a redirect with particular query string params needs to provide details to a target server. However, I need to ensure those details came from my origin server only.
Also I can't sure the integrity of the target server. Or specifically, the target server might be compromised so any encryption keys might have been read by a malicious party.
I'm thinking I could sign the query string using some form of public/private keypair. The origin server uses a private key to sign the string, and the target server uses a public key to verify it came from my origin server, and the message hasn't been tampered with.
I'm far from a cryptography expert or anything, so any assumption here I've made might be wrong, please correct me if so :)
I'm basically after a (hopefully) simple way to do this in Ruby.
Incrementing elements in SWI-Prolog
Well, since I'm practising "the Prolog logic" today and I found this unanswered problem in another thread here, I was wondering how it works.
increment every element of list by its depth, example
increment([0,0,[0]],[1,1,[2]]) -> true
And I almost thought that I like this language... :))
Is something like that possible? Thanks.

Why is a bad practice to distribute the Debug version of the application in .NET?
Reading this question, in the first comment, @Cody Gray says:
Erm, you know that you're not supposed
to redistribute the "Debug" version,
right?
I'm concerned about it. In Visual Studio, I usually develop my applications in Debug mode, and if I need to distribute the executable, all I do is zip the .exe and required .dll files (in bin\Debug folder).
Why is it a bad idea?
What is the difference between doing this and doing exactly the equivalent thing in Release mode?
Edit:
I asked this question time ago, but I just wanted to edit it to add a difference:
When using Debug.Assert in the code to test it, and compile in Release Mode, all those lines are gone, so that could be another difference.
