COPY is PostgreSQL's bulk-insert mechanism. It's a convenient way to transfer data between files and tables, but it's also far faster than INSERT when adding more than a few thousand rows at a time. Let's begin by creating sample data file. cat > samplet_data.csv 1,Yogesh 2,Raunak 3,Varun ...

Some Rust types implement the Copy trait. Types that are Copy can be moved without owning the value in question. This is because the contents of the value can simply be copied byte-for-byte in memory to produce a new, identical value. Most primitives in Rust (bool, usize, f64, etc.) are Copy. let x...

A shallow copy is a copy of a collection without performing a copy of its elements. >>> import copy >>> c = [[1,2]] >>> d = copy.copy(c) >>> c is d False >>> c[0] is d[0] True

If you have nested lists, it is desireable to clone the nested lists as well. This action is called deep copy. >>> import copy >>> c = [[1,2]] >>> d = copy.deepcopy(c) >>> c is d False >>> c[0] is d[0] False

You can create shallow copies of lists using slices. >>> l1 = [1,2,3] >>> l2 = l1[:] # Perform the shallow copy. >>> l2 [1,2,3] >>> l1 is l2 False

A dictionary object has the method copy. It performs a shallow copy of the dictionary. >>> d1 = {1:[]} >>> d2 = d1.copy() >>> d1 is d2 False >>> d1[1] is d2[1] True

Sets also have a copymethod. You can use this method to perform a shallow copy. >>> s1 = {()} >>> s2 = s1.copy() >>> s1 is s2 False >>> s2.add(3) >>> s1 {[]} >>> s2 {3,[]}

A lot of users find themselves in a situation where they just want to copy, move or delete a line quickly and return to where they were. Usually, if you'd want to move a line which contains the word lot below the current line you'd type something like: /lot<Esc>dd<C-o>p But to boost...

In Vim, these operations are handled differently from what you might be used to in almost any other modern editor or word processor (Ctrl-C, Ctrl-X, Ctrl-V). To understand, you need to know a little about registers and motions. Note: this section will not cover Visual Mode copying and cutting or ra...
