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.

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...

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...

Select last row in MySQL
...he primary key is how data is ordered in the database files (for InnoDB at least), and the RDBMS knows where that data ends, and it can optimize order by id + limit 1 to be the same as reach the max(id)
Now the road less traveled is when you don't have an autoincremented primary key. Maybe the prim...
