3,019,734 | 3,019,735 | handling php eval syntax error for mathematic equations | <p>suppose I do this in php:</p>
<pre><code>
eval("\$answer=1--1;");
</code></pre>
<p>The expression 1--1 will lead to a syntax error in eval, my question is how do I detect the error and handle it gracefully? ie: catch error in eval and then print out a helpful message. Right now, it just spits out "Parse error: syntax error, unexpected T_DEC". Unfortunately, the php manual states that it is not possible to catch parse errors with the set_error_handler() function.</p>
<p>This is for a simple school assignment and they have suggested using "eval()".
As the assignment is trivial, perhaps there is no need to worry about these rare cases.</p>

<p>When the user clicks on any input in the form, it is focussed. When a user clicks out of the form from any input it is blurred, but, the blur does not get triggered between tabbing between inputs in the form itself.</p>
<p>For something like this, we're looking at this basic structure:</p>
<pre><code><form>
<input ... />
<input ... />
<input ... />
</form>
</code></pre>
<p>So again, lets say I click on any input in the form, we know the form is focused. Next, when the user clicks off of ANY input the blur is triggered ONLY if we clicked outside the form.</p>
<p>I've asked this question previously and kindly received input on how to achieve the blurring effect when the last input field in the form was blurred, but not from any element in the input list.</p>

4,410,800 | 4,410,801 | 100K curl requests | <p>I am using curl_multi_exec to process over 100K requests. I do 100 requests at a time because curl_multi_exec can only handle 100 requests at a time to eventually get to 100K requests. We have added multiple servers to this system to spread the load [we are using load balancing]. What is the best way to have curl handle 100K requests and make use of these additional servers? What is the downside (other than time) of handling that many requests on one server? How can I use the additional servers to help handle those requests?</p>
<p>I was thinking about having each server handle a batch of requests (like one server handles 500 requests, another 500, another 500, etc.. </p>
<p>To elaborate- basically, we are using curl to send out over 100K requests to third party servers. The problem with only using 1 server is that there is a memory limit in the number of requests 1 server can handle. So we decided to add additional servers, but we are not sure how to design this system to use curl to handle that many requests..</p>
<p>The third party server is an API like Facebook; they are aware that we will be making that many requests to their servers.</p>
<p>For load balancing, we use Rackspace cloud server, basically the load balancer directs incoming requests to separate servers. </p>

5,045,243 | 5,045,244 | Virtual templates members of class workaround | <p>Let's say that I want to implement some classes for containers. All of them should implement such functions like insert, remove etc. So I write some interface:</p>
<pre><code>template <class T>
class ContainerInterface {
public:
virtual void insert(T element) = 0;
template<class Predicate>
virtual void remove(Predicate p) = 0;
};
</code></pre>
<p>Now I can write something like:</p>
<pre><code>template <class T>
class MyVector : public ContainerInterface<T>{};
template <class T>
class MyList : public ContainerInterface<T>{};
</code></pre>
<p>And I am sure that MyVector and MyList must implement functions insert and remove. However, there is the error:</p>
<pre><code>error: templates may not be ‘virtual’
</code></pre>
<p>It comes from:</p>
<pre><code>template<class Predicate>
virtual void remove(Predicate p) = 0;
</code></pre>
<p>I don't know the Predicate when I define some container and I dont'see any sense to bind deleter object to container class, for example one time I can pass Predicate to delete integers less than 50 and other time I want delete even integers. What can be done in such case - to declare some templated thing in base class and simulate virtual behaviour of function?</p>

<p>In the Orchard CMS there are config files all over the shop. There's even a config file in a folder containing only .CSS files! I'm new to larger-scale ASP.NET apps so...</p>
<p>Can someone just tell me if I'm right in my assumptions.</p>
<ul>
<li><p>The config file can affect server settings, and hence how a server processes a request to a resource further down a site structure.</p></li>
<li><p>From a code point of view, if the same line of code in the same class queries the config file during a request for <code>http://level1.resource</code> then it could read a different value to when the same code executes during a request for <code>http://level1/level2.resource</code> (if there is a web.config at level2)</p>

<p>Now to solve my problem, instead of referencing the very specific event I was looking at, I just used EventArgs, which seems to catch any possible event.

<p>Thanks.</p>
<p>Hi thanks for all your comments! Ok, I got it. Yes, indeed initially I started using
static functions in my class because they were not related to the objects of my class-
were doing some other operations. Now I also realized they needn't be public.
So, I think I'll leave them like this.
I started to get some errors when I removed static keyword (apparently due to the way it was used throughout class, so I am lazy now to fix those, will just make it private and leave static :)).</p>

546,372 | 546,373 | Can't store too lengthy int type | <p>Consider the problem:</p>

2^9 = 512
2^89 = 618,970,019,642,690,137,449,562,112
</code></pre>
<p>The results end in a string consisting of 1s and 2s. In fact, it can be proven that for every integer R, there
exists a power of 2 such that 2K where K > 0 has a string of only 1s and 2s in its last R digits.</p>
<p>It can be shown clearly in the table below:</p>
<pre><code>R Smallest K 2^K
1 1 2
2 9 512
3 89 ...112
4 89 ...2112
</code></pre>
<p>Using this technique, what then is the sum of all the smallest K values for 1 <= R <= 10?
Proposed sol:
Now this problem ain't that difficult to solve. You can simply do
int temp = power(2, int)
and then if you can get the length of the temp then multiply it with</p>
<pre><code>(100^len)-i or (10^len)-i
</code></pre>
<p>// where i would determine how many last digits you want.</p>
<p>Now this <strong>temp = power(2,int) gets much higher with increasing int that you can't even store it in the int type or even in long int</strong>....
So what would be done. And is there any other solution based on bit strings. I guess that might make this problem easy.

<p>Hi guys!</p>
<p>Is there a way to get the value of <code>this</code> from the function which has called the current function?
Look at this:</p>
<pre><code>function TraceMySelf(){
console.log(this);
}
function A(){
TraceMySelf();
console.log(this);
}
var a = new A();
</code></pre>

How can I make the code display the <code>a</code> object twice, with only changing line 2? I know that I could apply the function inside <code>A</code> with <code>this</code>, but that isn't what I want.</p>
<p>Is this possible?</p>

The action checkAtStart is supposed to display an alert if there is no text in field1 and hide startView if there is text in field1. checkAtStart works fine if assigned to a button, but when I try to run it using (void)awakeFromNib, the alert will display no matter what and startView will never hide. Its probably something really simple that I'm forgetting. Any help is appreciated!</p>
<p>Here is my code:</p>
<pre><code>- (void)awakeFromNib {
[self checkAtStart:self];
}
- (IBAction)checkAtStart:(id)sender
{
if (field1.text == nil || [field1.text isEqualToString:@""]) {
NSString *msg = nil;
msg = nil;
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:@"Test Message"
message:@"Test Message"
delegate:self
cancelButtonTitle:@"Close"
otherButtonTitles: nil];
[alert show];
[alert release];
[msg release];
}
else
{
startView.hidden = YES;
}
}
</code></pre>

<p>The function add does not have a return. I read that changes are available to only mutable objects like list. But why did the person omits the return? Either with or without return is fine. Why? This is so different from C++.</p>
<p>Thanks</p>
