What is the best way to identify unique devices for two-factor authentication?
Here's what I'm up to:
I'm collecting the username/password, and then I'm sending an authorization code to the user that they also need to enter before gaining access to the system (built in php). I don't want to bug...
Writing Stringbuilder to file asynchronously. This code takes control of a file, writes a stream to it and releases it. It deals with requests from asynchronous operations, which may come in at any time.
The FilePath is set per class instances (so the lock Object is per instance), but there is p...

My PHP contact form was recently being used to send spam. Some security measures have since been put in place (please refer to the comments below) and I'm seeking the collective wisdom of others to review the code and to check to make sure it is secure from injection attacks.

Imagine that I have int a = 123 and int b = 456.
How do I get a int c = 123456?

The Eclipse compiler is wrong.
Netbeans seems to have it right, what it is supposed to say, is:
'_' is used as an identifier
(use of '_' as identifier might not be supported in releases after Java SE 8)
So currently it is still okay to do so, but in future releases it might not be. This c...
I have a complex directory structure on my web server that includes .tar files for download; I'm trying to create a report on the size distribution of these files (e.g. 10 are less than 1MB, two are 1-2MB, three are 2-3MB...)
Is there a better way to organize this code? I started it as a consol...
This code is from a tutorial, I do understand most of it just not the array. I know array hold values in their indexes (array[1]=something, array[2]=something...)
But how does the array "keys" got the Keyboard.RIGHT value in the update function?

I have read several articles using google, but I somehow do not really get what they do, and when it is needed. Below I'll give 2 pieces of code, in one using get/set and in the other without, and they both work (atleast in this example). Could anyone give me an explanation of the difference, and...
After changing all variables (with the help from Magus (not sure how you link someone)) from public to private and adding get/set according to the need to get modified and/or read in another class, I'd like to know if this was done correctly.

This is the controller I created for my MVC framework, and I think I finally got it right.
Anything I can do to make the code more efficient?
Is this how a MVC controller is supposed to look like?

In order to build a domain model for my sales orders I have identified the following entities;

I will try not to give awful advice like I did last time. Here are a few remarks:
First of all, let's come back to std::forward. You should follow the link and read again a little bit more; std::forward is only useful for reference collapsing. In your operator(), you take the arguments by copy ...
We currently have three Meta tags that relate to topicality:
scope
on-topic
off-topic
A question about on-topicness or off-topicness (separately) are still about scope. A general question about topicality could still use all three and even site-policy. I've seen them used inconsistently som...
I have two IEnumerable objects called items and newItems. I need to update the Did and KeyDid property of each element in items with the matching Did and KeyDid from newItems. I can't just call items = newItems; since other things have a reference to items. Here's my code:
