connections (to a database, another server, ...)
The idea is to properly control the lifetime of the object:
it should be alive as long as you need it
it should be killed when you're done with it
The problem of GC is that if it helps with the former and ultimately guarantee...
How can you encode a string to Base64 in JavaScript?
...ike 'with' and from what I have read, 'eval' gets a bashing. All misplaced ideas on abuse. Personally I do not see why JavaScript needs to go down the route its going, it was never meant to be a program tightly bound and made more complex than it is already. If you want to be bound then make a compi...
Ignoring time zones altogether in Rails and PostgreSQL
...when applied to timestamp
Daylight Saving Time is not among the brightest ideas humanity ever came up with.
② Row 9, marked as loaded footgun works for me, but only by coincidence. If you explicitly cast a literal to timestamp [without time zone], any time zone offset is ignored! Only the bare ti...
How to pass objects to functions in C++?
...);
cout<< obj.getValue(); //output: 15
}
But this is not good idea as you will be ending up writing lot of code involving with pointers, which are prone for memory leaks and do not forget to call destructors. And to avoid this c++ have copy constructors where you will create new memory ...
INNER JOIN vs LEFT JOIN performance in SQL Server
...point out that there is basically no database documentation to support the idea that inner joins and outer joins performance differently. Outer joins are slightly more expensive than inner joins, because of the volume of the data and the size of the result set. However, the underlying algorithms (...

C++ - passing references to std::shared_ptr or boost::shared_ptr
... work with really, really know what you are all doing.
First, you have no idea how the interface to your class might evolve and you want to prevent other programmers from doing bad things. Passing a shared_ptr by reference isn't something a programmer should expect to see, because it isn't idiomati...
Why do I need 'b' to encode a string with Base64?
...omes a string. A string is a sequence of Unicode characters. base64 has no idea what to do with Unicode data, it's not 8-bit. It's not really any bits, in fact. :-)
In your second example:
