Encrypting & Decrypting a String in C# [duplicate]
...ewhat abstracted away within your "wrapper" class.
The following class is one I wrote a while ago to perform exactly the kind of thing you're after, a simple single method call to allow some string-based plaintext to be encrypted with a string-based password, with the resulting encrypted string als...
Traits vs. interfaces
...interfaces make our code less brittle. If you doubt this statement, ask anyone who's been forced to maintain legacy code that wasn't written against interfaces.
The interface is a contract between the programmer and his/her code. The interface says, "As long as you play by my rules you can implemen...
Practical usage of setjmp and longjmp in C
Can anyone explain me where exactly setjmp() and longjmp() functions can be used practically in embedded programming? I know that these are for error handling. But I'd like to know some use cases.

Creating a daemon in Linux
...g properly: ps -xj | grep firstdaemon
The output should be similar to this one:

Convert JavaScript string in dot notation into an object reference
...that this answer has gotten many upvotes, I am also somewhat horrified. If one needs to convert dot-notation strings like "x.a.b.c" into references, it could (maybe) be a sign that there is something very wrong going on (unless maybe you're performing some strange deserialization).
That is to s...
Token Authentication vs. Cookies
... I still don't understand why a token is better/different than a cookie. One way or another you are sending something to the api server that identifies a valid session. Assuming you are running everything on a single domain (and even if ember and your api are on different servers all you have to d...
The new keyword “auto”; When should it be used to declare a variable type? [duplicate]
...as it reduces the use of keyboard, without reducing the readability, as anyone can know the type of objects being created, just by looking at the code.
1. Avoid using new and raw-pointers though.
Sometime, the type is so irrelevant that the knowledge of the type is not even needed, such as in e...
How do I use reflection to call a generic method?
...ng reflection) and choose the best method to call. Here there is only this one generic method, so it's invoked with a proper type parameter.
In this example, the output is the same as if you wrote:
foreach (var o in objects)
{
MethodInfo method = typeof(Service).GetMethod("Process");
Metho...
Should I use tag for icons instead of ? [closed]
...e when you consider that the line between "text" and "icon" can be almost nonexistent on websites. Text may look like more like an icon (as in the Japanese example) or an icon may look like text (as in a jpg button that says "Submit" or a cat photo with an overlaid caption) or text may be replaced o...
Determining complexity for recursive functions (Big O notation)
... o);
recursiveFun4(n-1, m, o+1);
}
}
Here, it's O(2^n), or exponential, since each function call calls itself twice unless it has been recursed n times.
int recursiveFun5(int n)
{
for (i = 0; i < n; i += 2) {
// do something
}
if (n <= 0)
return 1;
