SomeModel.last(5) will execute the select statement without a limit, returning all records of SomeModel to Ruby as an array, after which Ruby will pick out the last (5) elements. Efficiency-wise, c...
What is the “FS”/“GS” register intended for?
...'re mostly dedicated to point to information about task control blocks, at least in the two major OSes now available for x86 chips. And, since they are no longer "general purpose" even for their original intent, you can't use them for much. Better to pretend on x86-64 systems that they simply do...
What is the best way to trigger onchange event in react js

Where and why do I have to put the “template” and “typename” keywords?
... exactly is a dependent name. On a simple read (you know, the principle of least surprise), all it defines as a dependent name is the special case for function names below. But since clearly T::x also needs to be looked up in the instantiation context, it also needs to be a dependent name (fortunate...
Remove everything after a certain character
...t works got the voting powers. Understanding the String methods is enough. Least understanding how things works and largest code rules the world :P So I added a step by step explanation to the split answer (to change the wolrd).

At least on SQL Server 2014, exec sp_databases did not work. The other two (master.dbo.sysdatabases and sys.databases) still work.

CSS media queries: max-width OR max-height
...wing evaluate as true:
The media type is 'screen' and
The viewport is at least 700px wide and
Screen orientation is currently landscape.
