Efficiency of purely functional programming
...an be intuitively explained very easily by looking at an implementation of arrays in a pure language (it costs lg(n) per operation (and you get history)).

How Drupal works? [closed]
...lize Configuration
This phase populates Drupal’s internal configuration array and establishes the base URL
($base_url) of the site. The settings.php file is parsed via include_once(), and any variable or string overrides established there are applied. See the “Variable Overrides” and “Strin...
Is Python strongly typed?
...;
On a little-endian platform with 32-bit integers, this makes i into an array of the numbers 0x64636261 and 0x00676665. In fact, you can even cast pointers themselves to integers (of the appropriate size):
intptr_t i = (intptr_t)&sz;
And of course this means I can overwrite memory anywhere...
mongodb group values by multiple fields
...resolve, which would allow a "limit" to the number of items to $push to an array.
db.books.aggregate([

"book": "$book"
},
"bookCount": { "$sum": 1 }

Catching error codes in a shell pipe
...
You can also check the ${PIPESTATUS[]} array after the full execution, e.g. if you run:
./a | ./b | ./c
Then ${PIPESTATUS} will be an array of error codes from each command in the pipe, so if the middle command failed, echo ${PIPESTATUS[@]} would contain someth...

What is data oriented design?
...on you should do this is that if data used together are placed in separate arrays, there is a risk that they will compete for the same slots in the cache. Thus loading one will throw out the other.
So compared to Object Oriented programming, the classes you end up making are not related to the ent...
How much is the overhead of smart pointers compared to normal pointers in C++?
...? This depends on your implementation. Let's say you are iterating over an array of 3 phases, each phase has an array of 1024 elements. Creating a smart_ptr for this process might be overkill, since once the iteration is done you'll know you have to erase it. So you could gain extra memory from not ...
Pure JavaScript equivalent of jQuery's $.ready() - how to call a function when the page/DOM is ready
...we have, do nothing. If we haven't yet been called, then loop through the array of ready functions and call each one in the order they were added. Set a flag to indicate these have all been called so they are never executed more than once.
Clear the function array so any closures they might be usi...
