Default constructor vs. inline field initialization
...n, then these may be overwritten in the constructors with arguments.
It is error-prone and besides with this way of valuing fields, the class decreases its reliability level. How could
rely on any default value assigned during the fields declaration while it has proven to be not reliable for two f...
Printing 1 to 1000 without loop or conditionals
...t: Added '&' so it will consider the address hence evading the pointer errors.
This version of the above in standard C, since it doesn't rely on arithmetic on function pointers:
#include <stdio.h>
#include <stdlib.h>
void f(int j)
{
static void (*const ft[2])(int) = { f, exit ...
Difference between shared objects (.so), static libraries (.a), and DLL's (.so)?
...r has to find the function bodies somewhere at link time or it'll raise an error. It ALSO does that at runtime, because as you rightly point out the library itself might have changed since the program was compiled. This is why ABI stability is so important in platform libraries, as the ABI changing ...
How can I access and process nested objects, arrays or JSON?
... using bracket notation:
const value = arr[5]; // arr.5 would be a syntax error
// property name / index as variable
const x = 5;
const value = arr[x];
Wait... what about JSON?
JSON is a textual representation of data, just like XML, YAML, CSV, and others. To work with such data, it first has t...
How do you sign a Certificate Signing Request with your Certification Authority?
...ivate key:
Sign the certificate? [y/n]:Y

TXT_DB error number 2
So unique_subject = no is perfect for testing.
If you want to ensure the Organizational Name is consistent between self-signed CAs, Subordinate CA and End-Entity certificates, then add the following to you...
@property retain, assign, copy, nonatomic in Objective-C
...elya - No. If you release while using ARC, I believe you'll get a compiler error.

Edit: to avoid the problem mentioned in the comments ('Error creating commit: Invalid request. For 'properties/name', nil is not a string.'), make sure you state a name in your profile on github.

Writing your own STL Container
... This is interesting. How does your tester work? There are several parse errors, which are trivial (missing ';') but not sure how that verify destructor works. Oh, you meant assert(tester::livecount == 0);. Mmmmm, still not sure how this tester framework works. Could you give an example?

Understanding typedefs for function pointers in C
...to 'signal()' set the handler to SIG_IGN and signal() returns the previous error handler, the value of old after the if statement must be SIG_IGN - hence the assertion. (Well, it could be SIG_ERR if something went dramatically wrong - but then I'd learn about that from the assert firing.)
