3,815,532 | 3,815,533 | Custom Liking Function - Do I need User Login? | <p>I've recently implemented a working custom liking/disliking function for my comics site.</p>
<p>but I feel it’s pushing me towards implementing a login system for all users… which I really don’t want to have to do (for my sake and my fans' sake)</p>
<p>Currently, the function works by:</p>
<blockquote>
<p>1) Passing button value (id = 'like' or id = 'dislike') via Jquery to
php script</p>
<p>2) script will first check if an ip exists in the database against
that given comic id... if not it will insert user's IP and current
comic ID and increment total likes for a given comic id... if it
already exists, it will remove that user’s information and decrement
total likes.</p>
</blockquote>
<p>The issue is, what happens if multiple fans “like” or “dislike” a comic from the same IP (net café, etc), or the same user goes and likes a comic from another computer…
So I was thinking the way to solve that would be generate a unique value for the user’s session and store it against their IP. </p>
<p>But what if that user wanted to come back at a later point after their unique session ID has expired and change their like to a dislike… how would the computer know it’s them?
Or what happens if the same user expires their session ID somehow (logs off then logs back in, closes browser, etc) and now can vote multiple times?</p>
<p>In this case, do I have to create a login system?</p>
<p>Thanks</p>

<p>For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask.

<p>I am a science guy writing a cfd (ish) code. I have created a class for all solving functions, and one that handles operations on a grid.

1,194,034 | 1,194,035 | What is the best way to pass server side variables to JavaScript on the client side? | <p>Our application uses a lot of configuration options. Those options need to be reflected on the client side in the form of User preferences, site wide preferences, etc.</p>
<p>Currently, we pass server side settings down to the client side in the form of JSON that is stored in custom attributes in the markup for a specific element (and no, our application currently doesn't worry about W3C validation). We then retrieve the data from the custom attribute, and parse it into a JSON object for use in script using jQuery.</p>
<p>One drawback to this is referencing attributes on elements from within event handlers. I know this is frowned upon, as it can create circular references, and subsequently memory leaks. I would much prefer to use jQuery's data function, but you can't invoke this from the server side at page render time.</p>

Anywho, the files are on a network drive so I currently use FileStream and BufferedStream to read them in, which depending on the file takes about 15 seconds.</p>
<p>My first question is there a faster way to do this? ReadLine made parsing easier, but clocked in at about 25 seconds.</p>
<p>Secondly, if the user is just playing around with one file alot (using different combos of filters and searches, whats the best way to deal with it in the applications memory?

I tried storing the whole file in a global StringBuilder which seemed to work, but I couldnt pass it on to other functions (OutOfMemoryException).</p>

4,735,443 | 4,735,444 | Registering derived classes in central list | <p>I have a central list of implementations of an interface and would like for derived classes to be able to register themselves in that list without having to add them in some central place. For example:</p>
<pre><code>// interface.h
struct MyInterface;
std::vector<MyInterface*>& InterfaceList();
struct MyInterface {
MyInterface() {
InterfaceList().push_back(this);
}
virtual ~MyInterface() {}
// ...
};
// derived.cpp
#include "interface.h"
class MyImplementation: public MyInterface {
public:
MyImplementation() {
}
// ...
};
MyImplementation impl;
</code></pre>
<p>This doesn't seem to work. For reasons I don't understand, the constructor of MyInterface never gets called - I would have thought that the instance of the derived class would call it at startup. I know it's possible to do something along these lines since I've seen other libraries doing it - but haven't managed to figure out what it is that I'm doing wrong.</p>
<p>Thanks :)</p>
<p>Edit: Sorry, missed a pair of braces and a reference. InterfaceList() is a function that returns a reference to a vector.</p>
<p>Edit part 2: Have now got it working in a reduced example, but can't get it to work in the files for the derived implementations - but that technique is working in another project. There must be something slightly different in those files which is causing it to fail - but it appears the problem isn't in the code I posted. Don't really want to post big chunks of my employer's projects though so I guess I'll have to keep fiddling myself. Thanks for the suggestions so far though :)</p>

5,748,219 | 5,748,220 | How to Connect to rild Socket | <p>I'm trying to write an app to talk to the rild. And Yes, I know this is not politically correct, but it's an embedded industrial telemetry app so I'm not concerned about user experience, portability and all that stuff.</p>
<p>The problem is that when I try to connect, I get a java.io "Permission denied" exception. Can anybody help me?</p>

mSocket.connect( mSockAddr );

srw-rw---- 1 radio system 0 Feb 13 19:14 rild-debug

<p>Could it be that the Dialer app is already connected and hogging the socket?</p>
